Abstract
A computer-implemented method for increasing safety during charging of a vehicle battery of a vehicle by a charging station, the method comprising the steps of calculating a forecast value for a maximum safe charging current by the controller of the vehicle based on sensor data generated by sensors of the vehicle and adjusting the charging current provided by the charging station in response to the forecast value of a maximum safe charging current.
Claims14
A computer-implemented method for increasing safety during charging of a vehicle battery of a vehicle by a charging station, the method comprising the steps of:
- calculating a forecast value for a maximum safe charging current by a controller of the vehicle based on sensor data generated by sensors of the vehicle, wherein the sensor data includes temperature sensor data by temperature sensors provided at measurement points of the vehicle, and wherein a temperature forecast for each measurement point is calculated by the controller of the vehicle by extrapolation on the basis of the rate of change of the temperature at the respective measurement point, and
- adjusting the charging current provided by the charging station in response to the forecast value of a maximum safe charging current.
A charging station comprising a control unit adapted to:
- continuously receive forecast values for a maximum safe charging current via a communication link from a controller of a vehicle connected to the charging station via a power cable for charging the vehicle battery in a charging process, wherein a forecast maximum safe charging current is determined by the controller of the vehicle iteratively based on calculated temperature forecasts for different temperature measurement points of the vehicle and communicated to the control unit of the charging station via the established wired or wireless communication link;
- and
- adjust automatically a charging current provided by the charging station via the power cable to the vehicle battery during the charging process in response to the received forecast values.
