Why Every Major Hotel and Hospital in India Needs 22kW Fast-AC Chargers

Overview

The EV switchover in India is now transitioning from early adoption to mainstream, and hospitality and healthcare campuses are turning out to be essential charging infrastructure points. For hotels and hospitals, setting up 22 kW fast-AC (three-phase) charging points is no longer a ‘green add-on’ but a fundamental infrastructure choice that impacts the bottom line, brand, and resilience.

However, solutions such as Savekar EV, which provide a WhatsApp + UPI-based charging management solution without the need for a dedicated app. They are making it easier to manage EV charging infrastructure at Indian hotels and hospitals. This article will discuss why 22 kW AC charging points are just right for Indian hotels and hospitals, how Savekar EV can help set up and monetize these charging points, and what one needs to know before embarking on this journey.

EV Adoption and Charging Demand in India

India's electric vehicle journey is gaining momentum – and speed. In fact, as per NITI Aayog estimates, the sales of electric vehicles in India have crossed the mark of 2.08 million units in the year 2024. This has resulted in a total of 5.45 million electric vehicles in the country. This equates to a market share of 7.66%, making it a significant achievement for the country. However, this is still a long way off from the country's ambitious goal of a 30% market share in the coming years.

The bigger picture looks even more promising. According to NITI Aayog and RMI estimates, electric vehicles could account for a staggering 70% of commercial car sales, 30% of private car sales, 40% of bus sales, and an astonishing 80% of two and three-wheeler sales in the country in the year 2030. These are not mere projections. This is a paradigm shift in the way India will be moving in the coming years.

The problem lies in the fact that the charging infrastructure has not caught up as well. The country has added a staggering number of charging points in the last year alone. The country experienced a major increase in public charging stations, which grew from 5,151 stations in 2022 to 26,367 stations by the start of FY25. The increase represents a major advancement. This number still remains low when compared to the number of electric vehicles in the country. The number of electric vehicles in the country remains alarmingly low when compared to the number of charging points.

It is for this reason that destination charging at hotels, hospitals, malls, and other similar places assumes so much significance in the current scenario. These places have vehicles parked for a minimum of a few hours. This is an ideal time for charging an electric vehicle without any additional effort.

The simple trend is clear: EVs are scaling faster than public chargers. This demand pressure will increasingly spill over into hotel and hospital parking.

Why 22 kW AC is a strategic "sweet spot."

Normal power yet fast enough

According to NITI Aayog’s EV charging handbook, “normal power” charging refers to charging up to 22 kW, as three-phase AC chargers up to 22 kW would be enough for e-cars with larger on-board chargers that would operate off the standard distribution network. This “normal power” charging would be enough for most Indian passenger EVs with battery capacities of 30 to 80 kWh.

A 7 kW AC charger would provide a range of 30 to 40 km/h, while a 22 kW AC charger would provide a range of 90 to 100 km/h, which is three times faster under ideal conditions. Commercial 22 kW AC chargers available for purchase in India indicate that it would take 2 to 4 hours to fully charge a four-wheeler or 45 to 90 minutes to provide substantial top-up charging, which would be suitable for hotel stays, restaurant visits, or hospital appointments.

7 kW vs 22 kW AC charging

Recognized in Indian standards and guidelines

The consolidated guidelines and standards for EV charging infra development issued by the Ministry of Power in 2022 explicitly mention the inclusion of Type-2 AC charging equipment with a minimum capacity of 22 kW as part of the standard fast-charging equipment for public charging infra, along with a capacity of 50 kW for DC charging equipment. The guidelines have referenced Indian standards such as IS 17017 and IS 15118 for Type-2 AC charging equipment.

Urban development and EV charging infra development guidelines issued by the central government ministries indicate the provision of charging infra for commercial buildings and public places such as hospitals, along with a minimum of one public charging station in each of the defined grids and a minimum number of charging bays based on the capacity of the parking lots. The above policy environment indicates that the installation of 22 kW AC charging equipment is not only commercially viable but also in line with government policies.

Why hotels specifically need 22 kW fast-AC chargers

Guest expectations and booking behaviour

As the number of EV owners increases, travellers are increasingly using filters for “EV charging” on online travel agencies and mapping sites. Booking.com and Google Maps already enable travellers to search for hotels offering EV charging facilities. This gives EV-ready hotels a significant competitive advantage over those that do not. Industry commentary suggests that those hotels offering EV charging facilities “instantly stand out” in a crowded marketplace because many competing properties do not have this facility.

The Indian EV charging companies demonstrate that hotels that provide electric vehicle charging facilities can attract business travellers who value sustainability and leisure tourists who desire environmentally friendly transportation options. Articles focused on hotels in India show that hotels should establish AC charging stations that provide 7.4-22 kW charging power throughout their parking facilities. These benefits include increased occupancy and dwell time for the hotel.

Why 22 kW (not just 7 kW) for hotels

Urban and luxury hotels face a problem of late arrival and early departure, and some guests stay for less than a day. Thus, guests using 22 kW AC charging will be able to drive for 100-200 km in 1-2 hours, while those using 7 kW AC charging will be able to drive for 30-80 km during the same period. Such a difference can mean that an EV guest is either “fully confident for tomorrow’s trip” or worried about range.

Exicom and EVRE, two suppliers, recommend smart AC charging points with 7.4-22 kW power ratings for hotel guest parking spaces, while DC Fast Charging points are recommended for highway or very short stay locations. The majority of luxury hotels in India already provide 22 kW AC charging stations through third-party operators, according to data from multiple hotels in the country. The online hotel directories contain information about Radisson Blu Hotel Ahmedabad, which provides two 22 kW AC charging points that are installed and maintained by specialist CPOs.

Revenue, upsell and brand advantages for hotels

Industry analysis indicates that hotels offering EV charging facilities reap additional benefits outside of room sales. These benefits include increased occupancy rates as customers remain in the hotel while their cars are charging, additional F&B and spa sales as customers remain in-house during charging sessions, and positive brand ratings as customers support environmental causes. The early implementation of 22 kW charging technology will help hotels establish themselves as advanced premium properties instead of backward facilities that must attempt to reach current standards.

The installation of EV charging stations serves as a brand component and ESG initiative, which combines with other sustainability programs to support industry development in both renewable energy and green building certification programs. The situation becomes especially important because hotels use their room and F&B services to attract guests who have similar choices between different hotels.

How Savekar positions hotels for EV-first guests

Savekar’s WhatsApp + UPI-based charging CMS is tailored for Indian property owners and already serves over 100 premium hotels and resorts for their EV charging infra. This helps the properties generate passive income without any software investment. The absence of an app download requirement and the need for customers to only scan a QR code and interact via WhatsApp removes any friction for customers during check-in and charging.

For property owners, Savekar provides real-time analytics and dynamic pricing along with UPI-based payments. The company also allows properties to retain 100% of charging revenue for a low annual fee for its CMS per charger. This, combined with 22 kW AC charging solutions, enables properties to be EV-friendly and easy to use for EV owners.

Why do hospitals specifically need 22 kW fast-AC chargers?

Serving staff, doctors, patients, and visitors

Hospitals operate continuously throughout the week because their staff members and patients require their services at all times. The research studies that have recently emerged demonstrate that hospitals in India, including AIIMS New Delhi and Apollo Hospitals, have started to establish EV charging stations at their parking areas to meet the charging requirements of their workers and visitors who consider charging to be an essential service.

Healthcare specialized EV charging service providers for the EV industry currently need to build EV charging systems because hospitals require those systems to develop their parking areas. The growing number of EVs and sustainability efforts in India will lead to more hospitals adopting EV charging systems, according to industry experts who predict that hospitals will start installing EV charging points in their facilities. The installation of 22 kW AC charging points in hospitals provides advantages for hospitals that require charging stations to support their electric ambulance operations while also serving public parking requirements.

Policy signals and category-specific guidelines

Indeed, the draft and final guidelines on EV charging infrastructure issued by the MoP identify hospitals as a category of institutions that should have charging stations that enable visitors to charge their vehicles and should be installed near the entrance, exit, or well-lit elevator core. These guidelines exist alongside overall guidelines that require at least one public charging station to be available in a commercial building that offers commercial EV charging services, effectively moving the hospital from an ‘optional’ to an ‘expected’ category.

For hospital administrators, installing 22 kW AC charging stations will not only enable their institution to meet emerging norms but will also enhance their role in ensuring that air remains clean while at the same time conveying an important message to environmentally conscious patients and partners that their institution cares about the environment.

Operational resilience and patient-centricity

Unlike driving along highways, hospital visits are usually unplanned and require a lot of stress. Having a reliable supply of 22 kW AC charging facilities in hospitals minimizes the chance of having to visit public charging points when they could be better focused on their visit. Having the opportunity for staff to charge their batteries for a long period of time during a 3-6 hour parking slot at a 22 kW charging point will be considerably more useful than a trickle charge from a low-power AC charger.

As electric ambulances and support vehicles come onto the scene, 22 kW AC charging points will be able to deal with many of the charging requirements for nighttime and between-shift charging without the expense and electrical wear and tear of a high-power DC charger.

How Savekar fits into hospital parking operations

Savekar’s platform is designed for multiple stakeholders on the campus, enabling hospital administrators to control access, pricing, and user groups such as staff, fleet, and visitors, through a cloud-based CMS. Since the charging is done through WhatsApp, the patient and the patient’s relatives don’t need to install an additional application in an already stressful visit, and the staff can easily access the application from their mobile phones.

The analytics and dashboarding provided in the application help the facilities team understand the utilization, energy consumption, and revenue, enabling them to plan for additional 22 kW slots, solar, and backup power, which is in alignment with the need for hospitals to ensure high availability, transparency, and governance in the infrastructure they provide to the public.

22 kW AC vs DC fast charging for hotels and hospitals

Cost and grid impact

On the other hand, DC charging solutions that operate in the range of 50 to 250 kW require higher capacity electrical infrastructure, separate transformers, as well as more sophisticated systems for cooling and safety, which greatly escalate capex as well as grid connection complexity. In contrast, a 22 kW three-phase AC charger would typically operate at a current of 32 A per phase at 400 V, which would easily integrate with existing infrastructure in a large number of commercial establishments that already have a three-phase grid.

Guidelines and handbooks for charging infrastructure development specifically focus on how AC charging solutions that operate at a higher power of 22 kW typically require no major upgrades to the grid infrastructure as compared to high-power DC charging solutions. Dynamic Load Management (DLM), which is typically built into AC charging solutions, would also enable hotels as well as hospitals to set a maximum limit for charger current draw to ensure that sanctioned demand is not exceeded.

Use-case fit and user experience

Rest stops and highway corridors can make use of 50-250 kW DC charging, where the need is to add hundreds of kilometres in 20-40 minutes. On the other hand, the dwell times at hotels, where the stay is overnight or longer, and hospitals, where the stay can be for multiple hours for OPD, day care, and admissions, can easily be handled by 22 kW AC charging, which is more than sufficient for most EVs.

For instance, a 60 kWh EV, with an SOC of 20% when it reaches the destination, can reach high SOC levels in the course of a hotel stay of multiple hours or a hospital stay of multiple hours for OPD, day care, and admissions, where the charging rate is an effective 11-22 kW AC, depending upon the onboard charger used in the EV, in accordance with the recommendations of EV charging service providers in India, where it is recommended that AC charging, with a range of 7.4-22 kW, should be the backbone for destination charging, with DC charging being used in a limited number of locations where the stay is extremely short.

Scalability and redundancy

As the cost of a single high-power DC fast charger can be several times that of a smart 22 kW AC charger, hotels and hospitals can afford more AC charging points with the same budget. Technical literature on charging infrastructure indicates that level 2 AC charging points with power ratings between 3.7 kW and 22 kW can be easily scaled up with multiple parking slots sharing a single transformer and smart charging controllers.

This is especially important for India as EVs are expected to gain traction with commercial fleets, taxis, and app-based mobility services that frequently interact with hotels and hospitals. Several 22 kW AC charging points ensure that several vehicles can charge at any given time at a decent rate, as opposed to one or two vehicles monopolizing a single high-power DC fast charger.

Business and revenue models for 22 kW chargers

Direct monetization models

Hotels and hospital premises can monetize 22 kW AC charging stations through several methods, including charging by kWh, charging by the number of sessions, or charging by bundling, i.e., “complimentary charging up to X kWh/night and then charging.” The guidelines issued by the Ministry of Power provide a single-part tariff system that should not exceed the average cost of supply for public charging stations up to March 2025. This has been advantageous in making the business of charging electric vehicles commercially viable.

As discussed in blogs by consultants and service providers on the economics of electric vehicle charging in India, 22 kW AC charging stations have an added advantage due to low hardware and installation costs compared to DC fast charging stations, which will enhance their payback periods due to low utilization levels, as experienced in the case of destination charging.

Zero-capex and partnership models

Partnership models are also developing in India, whereby charge point operators/energy service companies invest in chargers and operate them on hospital/hotel premises in exchange for revenue-sharing agreements and long-term rights. For instance, an MoU was signed by Energy Efficiency Services Limited, or EESL, with Apollo Hospitals for a 10-year agreement to install public charging stations at hospital premises.

Similar business models have been employed by private CPOs at hotel and mall premises, using ‘use and pay’ business models whereby users pay per use, and the premises owner does not incur any capital expenditures. For many hotel and hospital groups that may not want to commit capital expenditures, 22 kW AC charging becomes an operational decision rather than a capital-intensive one.

How does Savekar strengthen unit economics?

Savekar’s CMS costs around ₹1,999 per year per charger, which is relatively low when compared to the O&M costs of charging stations installed in commercial establishments. Even Savekar’s earnings calculator indicates that a 10-charger system with CMS and service costs ranging from around ₹69,990 per year will result in an estimated net profit of around ₹5.6 lakh per year at moderate utilisation levels, thus indicating a payback period of around 9 months.

Since the property gets 100% of the charging revenue, sets its own rate per kWh, and there’s no lock-in period, Savekar’s system appears to be particularly suited to hotels and hospital premises that require flexibility while waiting to see how the pattern of EV charging develops at their premises. This will enable easier justification of installing multiple 22 kW AC charging points rather than experimenting with one or two sockets.

Indirect revenue and strategic value

In addition to direct charging income, the knowledge that high-quality 22 kW AC charging is available makes a hotel or hospital more appealing to customers, users, or corporate partners, thus driving occupancy, length of stay, or satisfaction scores.

In hospitals, this also opens opportunities for corporate health programs or insurer/employer partnerships that focus on sustainability in their provider selection criteria.

In the medium term, having EV infrastructure in place opens opportunities for new business models such as managed charging for fleets of taxis, ambulances, or staff transport, or for solar PV/battery systems that offer cheaper, cleaner energy.

Hotels that act early will not just be destinations, but also hubs for mobility in their area.

Implementation roadmap for facility managers (with Savekar)

1. Assess demand and use cases

The facility teams should also estimate the near-term and medium-term EV demand, such as the percentage of the current guests/staff that they anticipate will be driving an EV, the projected EV demand in the surrounding area, and the potential electrification of their fleet. This will involve analyzing factors such as room nights by business or pleasure use, length of stay, and highway access for hoteliers, and staff and emergency response needs for hospitaliers.

Using these data inputs, facility teams will be able to determine the number of charging stations to install initially, such as 2 to 6 charging stations with 22 kW AC charging capability for a mid-size property, and reserve space and cabling for future expansion based on projected demand. National and urban government guidelines that provide minimum public charging station targets, such as one public charging station per defined grid, may be used as a starting point.

2. Conduct electrical and civil feasibility

The electrical audit involves a detailed analysis of the sanctioned load, transformer capacity, existing feeder plan, and diversity of other loads to determine the number of 22 kW AC chargers that can be initially supported. The technical standards together with the planning guides establish that standard circuits can support regular power AC charging up to 22 kW when the system components undergo proper design for wiring and protection, and earthing needs.

Civil planners need to choose parking bays that provide good illumination and visibility to drivers who need to access building entrances and elevators and drop-off zones. It is also crucial for hospitals to ensure that the electric vehicle bays do not interfere with the emergency routes while at the same time ensuring ease of use for patients and hospital staff.

3. Selection of hardware and software platform (Savekar + 22 kW AC)

For the case of hotels and hospitals, it is important to select OCPP-compliant smart 22 kW AC chargers that can perform remote monitoring, RFID/app-based (or QR code-based) authentications, and load management dynamically. Generally, the 22 kW AC chargers in India have Wi-Fi, GSM, and LAN connectivity options, power protection, surge protection, and IP-rated enclosures for outdoor use, making it possible to install these charging stations in the parking lot, both in the basement and the open parking lot.

The CMS layer of Savekar is then used for the user interface and revenue collection, where the customer can scan the QR code attached to the charging station, start the session, and make the payment directly through WhatsApp without the need to install any new application or wallet.

4. Decide on Operating Model and Tariffs

The management has to decide if EV charging has to be purely an amenity, a profit centre, or a mix of both. Some hotels in India offer free AC charging for in-house guests and charge non-guests by the session or unit of energy. Others charge for all sessions but at low margins to induce more customers. Some hospitals might choose convenience over profitability for their staff and patients, but charge for the electricity used.

The subscription-based model of Savekar’s CMS and direct UPI transfer make it easy to test various tariff models without having to change hardware or commit to a specific CPO. There is no lock-in period, so hotels can change models as charging demand increases, seasonal patterns become more evident, and new segments such as cabs, ambulances, and staff cars start using the charging points.

5. Plan for future growth and integration

The national targets for EV adoption are very ambitious, as are the growth rates for public charging station deployment. As a result, it is important to consider how the 22 kW AC charging deployment will be easily extended in the future. This will include oversizing ducts, additional bays, and modular switchgear. It is likely that hotels and hospitals will be able to easily add more chargers, solar power, or even limited DC fast charging as required.

The technical handbooks highlight that developing a strong normal power AC charging infrastructure up to 22 kW per charger is the cost-effective approach to developing an EV-ready site, providing flexibility for future upgrades. With Savekar’s dynamic load management and remote management capabilities included as part of the CMS, expanding from a pilot number of chargers to campus-wide deployment is operationally feasible.

Conclusion

India’s EV revolution is changing perceptions of what basic infrastructure means for large hotels and hospitals, and 22 kW three-phase AC charging is proving to be the de facto solution for destination charging at these locations. It is fast enough to make a difference during the stay, it is supported by existing Indian standards and guidelines, and it is far more economical and scalable than high-power DC for hospitality and healthcare infrastructure.

With Savekar’s WhatsApp + UPI-based CMS, hotels and hospitals can now implement guest-friendly, staff-friendly, and easy-to-operate fast AC charging that is easy to monetize and quick to pay back. For large hotels and hospitals in India, it is no longer a question of whether or not they should implement 22 kW fast AC charging, but when and with whom they should do it.

Postscript: Technical Notes on 22 kW Fast-AC Charging

1. The electrical characteristics of 22 kW three-phase AC define the performance of all 22 kW three-phase AC chargers. The charger will operate at 400 V while drawing 32 A current from the three-phase supply. The three-phase AC system will operate at a power level given by P = \sqrt{3} * V * I, resulting in an apparent power rating of 22 kW at 400 V and 32 A.

The Indian standards (IS 17017 series) define Parkbay AC charge points to operate at normal power levels of 11 kW or 22 kW, which match the international Type‑2 AC charging standards. The technical documents explain that chargers that exceed 3 kW need higher-amperage branch circuits plus two-phase or three-phase electrical connections that commercial buildings typically use.

2. Charging times for typical EV battery sizes

The handbook published by NITI Aayog for EV infrastructure development suggests that typical e-car batteries are of capacities ranging between 30 and 80 kWh for second-generation passenger EVs. A theoretical calculation suggests that a 44 kWh capacity pack could be charged in about 2 hours, and a 66 kWh capacity pack could be charged in about 3 hours.

However, charging providers’ practical advice suggests that a 22 kW AC charger adds about 37-50 miles of range per hour of charging time, as compared to about 30-40 km of range per hour of charging time for a 7 kW charger. This explains why commercial-grade 22 kW AC charging stations in India are claimed to be able to substantially charge four-wheelers in about 45-90 minutes and charge them completely in about 2-4 hours.

3. Onboard charger limitations and compatibility

The actual charging capacity of an AC charger is limited in practice by the lower capacity of either the EVSE equipment itself or the vehicle’s onboard charger. The onboard charging capacity for global mass-market electric vehicles currently ranges from 7 to 11 kilowatts but does not exceed 22 kilowatts. An electric vehicle will charge at its highest onboard charger capacity when connected to a 22-kilowatt AC charger instead of using the charger's maximum charging capacity. The system enables users to access both the strong and adaptive features that the charger provides.

It has been emphasized in technical guides that three-phase AC charging equipment up to 22 kW is particularly useful for vehicles that have larger onboard charger capacities. This means that as manufacturers start increasing the capacities of onboard AC chargers in their vehicles, sites that have already adopted the 22 kW AC charger will be able to support newer vehicle generations.

4. Communications, Control, and Smart Technologies

In India, newly installed charging stations with 22 kW AC capacity can operate using OCPP 1.6 or OCPP 2.0.1. OCPP 1.6 and OCPP 2.0.1 enable charging stations to connect with various back-end systems. The feature operates as a crucial requirement for multi-stakeholder operational environments that include hotels and hospitals.

Dynamic Load Management will enable multiple 22 kW charging stations to share a common power budget. This feature will enable the charging stations to operate within the allowed limits of the transformer or feeder. This feature would also be useful in a retrofit scenario, as it might not be feasible or might take too long to increase the sanctioned load, but the property owner would like to provide several charging points.

5. Safety, Protection, and Environmental Compliance

The technical briefs and data sheets related to 22 kW AC charging stations used in India emphasize the compliance of the charging stations with IEC and BIS standards. These standards may require compliance with insulation monitoring, overcurrent/short circuit protection, and residual current devices. Some charging stations deployed in commercial environments may have an IP54 or better rating and may be designed to operate in outdoor or semi-outdoor environments.

Guidelines given by ministries and departments of safety have indicated that adapters should not be used to connect vehicle connectors with vehicle inlets. It is necessary to adhere to the safety rules and standards of the grid as outlined by the Central Electricity Authority. In the case of hospitals and hotels, it is necessary to use and install 22 kW fast AC charging stations.
