Industry
Energy Storage
Battery cells are sensitive to temperature and temperature spread. Liquid-cooling units use a circulation pump to drive coolant through cold plates under the battery modules, keeping cell temperature and spread in range and extending cycle life.
Overview
Overview
The safety and life of an energy storage system depend heavily on cell temperature. Compared with air cooling, liquid cooling exchanges heat more efficiently and evenly, and has become the mainstream solution for large storage systems.
The circulation pump in the cooling unit runs continuously outdoors over a wide temperature range while adjusting flow to the battery’s charge and discharge load.
Key challenges
- 01 Temperature uniformity Cell temperature spread affects consistency and life, so loop flow must be even and steady.
- 02 Outdoor conditions Container systems face heat, frost and condensation; pumps need wide temperature range and high protection.
- 03 Long, maintenance-free life Storage systems run for many years and the pump's reliability must match.
- 04 Cost and size Limited space calls for a highly integrated pump, motor and controller.
Scenarios
Applications
-
Container BESS cooling units
24 / 48 V DC canned pumps with PWM or CAN control, adjusting flow with cell temperature.
Recommended: CP-D DC canned pump -
C&I storage cabinets
Small to medium flow and low noise for installation close to users.
Recommended: CP-D DC canned pump -
PCS and power electronics
Liquid cooling of inverter IGBT modules with reliable continuous duty.
System solution
Battery cabinet cooling loop
The chiller cools the coolant, the pump sends it through distribution lines into each battery module's cold plate, and the warm coolant returns to the chiller.

Case study
Cooling unit pump for container energy storage (sample case)
- Challenge
- Outdoor operation from -30 to +50 °C, CAN speed control and fault reporting, very compact installation space.
- Solution
- CP-D48 series with integrated pump, motor and controller, on CAN 2.0B to the unit controller and regulated by cell temperature.
- Result
- Stable loop flow and reduced speed at low load, cutting noise and energy use. (Sample content; real case to follow.)
