Will hotel guests have enough charge by checkout?

A guest asks whether the hotel has EV charging. “Yes” can mean a working wall unit beside an available parking bay. It can also mean an ordinary socket, a connector that does not fit the car or equipment staff cannot start.

For a hotel in Pokhara, Chitwan or a hill town, those differences affect the next morning's departure. The sensible investment begins with the guests' parking time and energy needs. A charger bought mainly for its impressive rating may be the wrong equipment for an overnight stay.

An overnight guest buys time as well as electricity

Assume a guest needs 20 kWh added to the battery and charging efficiency is 90%. The supply must deliver about 22.2 kWh. At a steady 3.3 kW that takes roughly 6.7 hours, while at 7 kW it takes about 3.2 hours. The car's AC limit, installation and charging conditions can change the time.

If the car is parked from 7 pm to 7 am, either example may fit. If the hotel expects day visitors to stop for lunch, the same equipment offers a very different service. Decide whether the main job is overnight charging or a short public stop before selecting hardware.

Confirm which cars your guests use and which inlets they have. Nepal directories list different connector standards; the CG Motors network page illustrates why “EV charger” alone is insufficient information. Do not promise universal compatibility through an adapter unless the vehicle and equipment manufacturers approve the arrangement.

Check the spare electrical capacity

A qualified electrical designer should assess the existing supply and concurrent hotel loads. Cooking, hot water, pumps and air conditioning may already use much of the available capacity. The installation needs suitable protection, earthing, cable routing and weather exposure provisions.

Two nominally 7 kW units can create about 14 kW of charging demand if both run at full power. Managed equipment may share an agreed limit, but that capability needs specification and commissioning. It should not depend on a receptionist remembering to unplug one guest's car.

NEA's annual report includes transport electricity tariffs with distinctions by supply and time. Obtain the applicable connection and billing arrangement from the local NEA office. A domestic tariff copied from an owner's blog is not a hotel business quotation.

Ask separately about connection upgrades, demand charges where applicable and metering. These fixed costs can matter when the equipment is used only occasionally.

Make the reservation specific

The booking page should give the connector, maximum available power, access conditions, price basis and whether a bay can be reserved. Explain if power is shared. Say whether charging is for staying guests, restaurant customers or the public.

A guest should be able to describe the car before arrival and receive a useful answer. Staff need photographs of the connector and a simple operating procedure. They should know where the isolation control is, how to contact support and when damaged equipment must stay out of service.

Plan for occupied bays. Does a guest have permission to remain parked after charging ends? Can staff contact the driver to move? Is there a waiting list or a booking slot? Those decisions should appear in the terms rather than becoming an argument at midnight.

Revenue is not the same as profit

Suppose the hotel sells 20 kWh in a session at an assumed Rs 25 per kWh. Gross charging revenue is Rs 500. If purchased energy and losses cost Rs 250 for that session, the difference is Rs 250 before maintenance, payment costs, taxes, staff time and equipment recovery.

One such session on 15 nights generates only Rs 3,750 of that simplified monthly contribution. Three sessions on each of those nights would generate Rs 11,250, if the same assumptions and capacity hold. These are illustrations, not a proposed tariff or a prediction of occupancy.

If charging is included in a room rate, its value may appear in bookings or guest retention rather than charging revenue. Measure that separately. A claim that every charger pays for itself in one year needs actual installation costs and utilisation evidence.

AEPC's grid-connected solar planning resources can help where the hotel is also considering solar. Solar output, guest charging time and any storage need a separate design; “solar charger” does not guarantee electricity after sunset.

Reliability needs an owner

Assign responsibility for checking the equipment, updating guest information and handling faults. Keep a record of failed sessions. Distinguish a compatible car that could not start from a car with the wrong inlet.

After flooding or damage to the parking area, have the equipment assessed before restarting it. Clean-looking connectors do not prove the installation is safe. Give guests a verified alternative when service is unavailable, and update the booking page promptly.

Keep a departure record for booked charging sessions: energy requested, energy delivered and any problem reported. If guests repeatedly leave short of the agreed charge, investigate the equipment, bay access or booking schedule before advertising more charging capacity.
