How does the battery cooling system work

How does the battery cooling system work?

1、The main components of the battery liquid cooling system

Electronic water pump—Driving the coolant in the system to circulate in the pipeline and continuously cool down.

Liquid piping—Providing a flow path for the coolant to contact and cool the power battery module.

Condenser—Radiating the heat absorbed by the coolant to the atmosphere.

Heat Exchanger—Transferring the heat generated by the battery to the coolant.

Compressor: Further enhance the cooling capacity.

2、Battery liquid cooling system working principle

When the power battery warms up and needs to be cooled, the power battery will exchange heat with the coolant through the cooling plate.

The coolant is sent into the heat exchanger by the electronic water pump. Inside the heat exchanger, one side flows into the refrigerant, and the other side flows into the hot coolant, and exchange heat in the heat exchanger.

The heat is taken away by the refrigerant and the cooler coolant flows out and back to the battery, creating a cycle.

The hotter refrigerant then dissipates the heat through a customized compressor and condenser, creating a cycle.

In some cold countries, the power battery need to be heated. By using PTC liquid heater which works by first closing the cooling circuit and turning on the PTC liquid heater. The coolant is heated by the PTC and flows to the battery, where it is heated by the cooling plates.

3、Battery liquid cooling system advantages

Good cooling effect: Compared with air cooling, liquid cooling effect is better and more stable. It can completely solve the problem of power battery overheating.

Strong applicability: compared with refrigerant direct cooling and immersion cooling, it is more applicable. The requirements for the environment are not so harsh.

Strong controllability and high precision: the system collects temperature data in real-time and intelligently adjusts parameters such as coolant flow and condensing fan speed. This can achieve a balance between precise control of power battery temperature and energy saving.

Cling BTMS works under the command of BMS, battery management system to output capacity to cool or heat the coolant carrier avoide battery performance declines and battery cells either become volatile or too dull.
