Abstract
System for regulating a charging temperature (T) of a vehicle battery (2) of a vehicle, wherein the vehicle battery (2) is cooled by means of a fluid (F) which circulates in a cooling circuit (21) of the vehicle, which is controlled by a controller (18) such that, upon reaching a charging station, the temperature of the vehicle battery (2) is pre-controlled to a desired charging start temperature (T0) which is suitable for an electrical charging procedure for speedily charging the vehicle battery (2) by means of the charging station.
Claims14
A system for regulating a charging temperature of a vehicle battery of a vehicle at a charging station, comprising:
- a cooling circuit in the vehicle configured to cool the vehicle battery only by means of a fluid which circulates in the cooling circuit of the vehicle which is controlled by;
- and
- a controller configured and operable to control said cooling circuit such that, upon reaching the charging station, the temperature of the vehicle battery is pre-controlled to a desired charging start temperature which is suitable for an electrical charging procedure for speedily charging the vehicle battery by means of the charging station, wherein a quantity of the fluid circulating within the cooling circuit is dimensioned such that, without external cooling a maximum permissible temperature of the vehicle battery is not reached during an electrical charging of the vehicle battery from 10% of its battery charging capacity at the beginning of the electrical charging procedure to 80% of its battery charging capacity at the end of the electrical charging procedure.
