Battery Liquid Cooling System for EV and Energy Storage

A battery liquid cooling system is an essential thermal management solution for electric vehicles (EVs) and battery energy storage systems (BESS). It uses circulating coolant, typically a water-glycol mixture, to remove heat generated during battery charging and discharging, helping maintain stable operating temperatures and improve battery reliability.

How Does Battery Liquid Cooling Work?

The system circulates coolant through aluminum cold plates installed in close contact with battery modules. The coolant absorbs heat and transfers it to a heat exchanger for dissipation.

A typical liquid cooling system consists of:

Aluminum cold plates

Coolant distribution manifolds

Circulation pumps

Heat exchangers

Temperature sensors and control units

Compared with air cooling, liquid cooling offers more efficient heat transfer and better temperature uniformity, making it suitable for high-density battery applications.

Key Benefits of Liquid Cooling

Efficient Heat Dissipation: Removes heat effectively during high-power charging and discharging.

Temperature Uniformity: Reduces temperature variations between battery cells and helps maintain consistent performance.

Compact Integration: Customized aluminum cold plates support different battery pack structures and installation requirements.

Operational Reliability: Proper coolant distribution and temperature control support long-term battery operation.

Applications in EV and ESS

Battery liquid cooling is widely used in passenger EVs, commercial electric vehicles, and large-scale energy storage systems.

For EV battery packs, it helps manage heat during fast charging and high-power operation. For BESS applications, it supports stable thermal management during continuous charge and discharge cycles.
