METHOD FOR COOLING BATTERY SYSTEM

摘要

PROBLEM TO BE SOLVED: To maintain a battery cell within a desired temperature region, in a battery pack.SOLUTION: A cooling system for a battery system and a method for cooling the battery system are provided. The cooling system includes a housing having first and second enclosed portions, and a first evaporator and a first evaporator fan disposed in the first enclosed portion. The first evaporator fan recirculates air in a first closed flow path loop within the first enclosed portion. The first evaporator extracts heat energy from the air in the first closed flow path loop to reduce a temperature level of a first battery module in the first enclosed portion. The cooling system further includes a condenser disposed in the second enclosed portion and fluidly coupled to the first evaporator. The condenser receives heat energy in a refrigerant from the first evaporator and dissipates the heat energy. The cooling system further includes a compressor disposed in the second enclosed portion and recirculating the refrigerant through the first evaporator and the condenser.
