Abstract
A liquid cooling circuit for a storage battery, with which a motor vehicle of the electric or hybrid type is equipped includes a main loop for the circulation of a heat transfer fluid, the main loop is connected to elements for cooling the storage battery, and a first bypass connects the main loop to an air cooling radiator, and a second bypass connecting the main loop to a heat exchanger intended to be connected to an air conditioning system with which the motor vehicle is equipped, so as to cool the heat transfer fluid by means of the radiator and/or the heat exchanger of the air conditioning system. The main loop is connected to the first bypass by way of a first progressive three-way valve, and the main loop is connected to the second bypass by way of a second progressive three-way valve.
