Application of Liquid Cold Plates in Battery Energy Storage Systems (BESS)

Application of Cold Plates in BESS

 

Cold plates are a mainstream thermal management solution for high-density, large-scale Battery Energy Storage Systems (BESS), featuring high heat exchange efficiency, precise temperature control, and excellent spatial adaptability.

1. Core Working Mode

Mounted closely to battery modules (embedded or bonded), cold plates transfer heat from battery cells via coolant circulating through their internal flow channels.

2. Typical Application in Containerized BESS

  • Custom Design: Tailor flow channel structures (parallel/serpentine) based on cell layout to maximize contact area.
  • System Integration: Combine cold plates with modules, circulation pumps, heat exchangers, and valves to build a closed-loop liquid cooling system.
  • Smart Regulation: Link with BMS to dynamically adjust coolant flow rate according to real-time cell temperature for optimal energy efficiency.

3. Application Value & Trend

Cold plates improve BESS safety, extend battery life, and optimize space utilization. They are evolving toward integration, lightweight design, and intelligence to support large-scale BESS commercialization.
