EP2147475: SYSTEM FOR COOLING A BATTERY
Invention relates to a system for cooling an energy storage system of a hybrid electric vehicle. The energy storage system includes at least one energy storage device, including a maximum temperature storage device with a maximum temperature and a minimum temperature storage device with a minimum temperature. The system includes a cooling fluid duct in flow communication with an inlet and the at least one energy storage device, and a blower positioned within the cooling fluid duct to draw cooling fluid into the inlet and through the cooling fluid duct. The system further includes a controller coupled with the at least one energy storage device to increase the temperature of the at least one energy storage device having a temperature below the maximum temperature reduced by at least a predetermined threshold. The cooling fluid duct and blower are coupled to form a common cooling system for the at least one energy storage system.
