Abstract
A method and a device are provided for the efficient charging of a vehicle battery of an electric vehicle by a charging station of a group charging station. The connected vehicle battery, starting from an initial charge state, is charged in accordance with a calculated charge priority value until the charge state of the vehicle battery reaches a selectable charge state. The calculated charge priority values of the vehicle batteries connected at the same time to the charging stations of the group charging station determine which batteries will be charged within a charging interval.
Claims17
A method for efficient charging of a vehicle battery of an electric vehicle by a charging station of a group charging station, which comprises the steps of:
- charging a connected vehicle battery, starting from an initial charge state, in accordance with a calculated charge priority value until a charge state of the connected vehicle battery reaches a selectable charge state;
- and
- using calculated charge priority values of vehicle batteries connected at a same time to charging stations of the group charging station to determine an order with which different vehicle batteries will be charged within a charging interval.
A group charging station for efficient charging of at least one vehicle battery of an electric vehicle, the group charging station comprising:
- charging stations for connecting to vehicle batteries, and starting from an initial charge state, a vehicle battery being charged in accordance with a calculated charge priority value until a charge state of the vehicle battery reaches a selectable end charge state, whereby calculated charge priority values of the vehicle batteries connected at a same time to said charging stations of the group charging station determine a choice of how different vehicle batteries will be charged within a charging time interval by the group charging station.
