How does a Liquid-cooled Energy Storage System Work?

With the popularity of electric vehicles, liquid-cooled energy storage systems have also become an indispensable part of electric vehicles. A liquid-cooled energy storage system is a system that cools batteries through liquid circulation, and a system that controls the temperature of semiconductor devices within an appropriate range. It usually consists of a cooler, heat exchanger, controller and sensors. It works as follows.

1. Radiator

The radiator in the liquid-cooled energy storage system is the core component of the whole system. The heat sink absorbs the heat generated in the battery by circulating fluid and dissipates it to the external environment. Heat sinks are usually made of aluminum and have good heat dissipation properties.

2. Liquid circulation

Liquid circulation in liquid-cooled energy storage systems is achieved by pumps. The liquid flows out of the battery, passes through the heat sink to dissipate heat, and then flows back into the battery. The speed and flow of liquid circulation can be adjusted by controlling the speed of the pump to achieve the effect of heat dissipation.

3. Temperature sensor

The temperature sensor in the liquid-cooled energy storage system is used to monitor the temperature of the battery. When the temperature of the battery is too high, the temperature sensor will send a signal to the control system, and the control system will automatically adjust the speed and flow of the liquid circulation to achieve the cooling effect.

4. Control system

The control system in the liquid-cooled energy storage system is the brain of the whole system. The control system controls the speed and flow of the liquid circulation by monitoring the signal of the temperature sensor to achieve the cooling effect. The control system also monitors the charge and status of the battery and charges or discharges it as needed.

The liquid-cooled energy storage system is a system that cools the battery through liquid circulation. Its core component is the radiator. The liquid circulation is realized by the pump. The temperature sensor is used to monitor the temperature of the battery. The control system monitors the temperature of the temperature sensor Signal to control the speed and flow of liquid circulation to achieve cooling effect. The emergence of liquid-cooled energy storage systems provides strong support for the development of electric vehicles and brings more convenience to our lives.
