Bidirectional charging · Stop 02V2L, V2H and V2G: what is the difference?Vehicle to load, to home and to grid: three ways a car can give energy back, and how far each reaches beyond the car.

V2H powers the house. In island mode the house is separated from the grid; in parallel with the grid, the energy stays in the house installation, and car and inverter must meet the rules for generation units and storage, in Germany VDE-AR-N 4105.

  1. InverterPower electronics that turn the battery's direct current into alternating current for the motor, and back when the car regenerates.
  2. V2GVehicle to grid: the car feeds energy into the public grid; because one car's effect is small, many cars are usually pooled by an aggregator.
  3. V2LVehicle to load: the car powers a device through a socket, without the grid.
