How much power does a depot need?

Start from the routes: energy per vehicle and night, divided by the hours available. With load management, the connection can be far below the sum of all chargers.

Fleet charging · Stop 03How is a depot planned?Routes, energy per night, the time window and the grid connection: how a depot's charging is sized, and how much spreading the load over the night saves.

Planning starts with the routes, not the chargers. In the example, each van drives about 120 km a day; at an assumed 0.25 kWh per km including charging losses, it needs 30 kWh a night. Thirty vans need 900 kWh. Between 4 PM and 6 AM there are 14 hours, so on average the depot needs about 65 kW, far below the peak of all chargers at once.
