A method of charging an electric vehicle includes receiving data indicative of the power source system voltage during charging, determining a maximum voltage limit of the power source, and setting the maximum voltage limit as the limiting voltage of the power source. The maximum voltage limit may be the maximum permissible value of the system voltage during the charging.

Limiting voltage spikes during electric vehicle charging

Vehicle depots or yards adapted to charge multiple electric vehicles include multiple charging electrodes to simultaneously direct power to multiple electric vehicles. The charging electrodes may direct power to the electric vehicles from an utility grid or from a secondary power source.

Depot charging of an electric vehicle fleet

A method of charging an electric vehicle at a charging station includes electrically connecting the charging station to the vehicle. The charging station may be configured to charge the vehicle using a charging station charge protocol and the vehicle may be configured to receive the charge using a vehicle charge protocol. The vehicle receives a signal indicative of the charging station charge protocol and selects the vehicle charge protocol based on this signal. The vehicle is then charged using the selected vehicle charge protocol. While selecting, the vehicle may select one charge protocol from multiple charge protocols supported by the vehicle to match the charging station charge protocol.
