Cooling system for cooling batteries of e.g. electric car, has heat conveying system adapted to transfer calorific energy released by batteries toward evaporator of heat pump for controlling temperature of passenger compartment of vehicle

摘要

The system (1) has a heat conveying system e.g. gravitating heat pipe (2), adapted to transfer calorific energy released by batteries (3) toward an evaporator (5) of a heat pump (6) for controlling temperature of an passenger compartment of an vehicle. The heat pipe is located below the evaporator of the heat pump. A direct cooling system (22) of the batteries is activated under operation at an external threshold temperature, which is higher than zero degrees Celsius and lower than 5 degrees Celsius, where batteries are cooled by the cooling system beyond the temperature. An independent claim is also included for a method for cooling batteries of an electric car or hybrid car.
