Multiple Operating Modes for Commercial Battery Storage

Self-Consumption

Store available energy and use it later to increase on-site energy utilization.

Peak Shifting

Charge during lower-demand periods and discharge when site demand increases.

Forced Charging

Schedule battery charging according to the project's operating strategy.

Forced Discharging

Discharge stored energy according to predefined site requirements.

Liquid Cooling for Consistent Battery Operation

For a liquid cooled BESS, effective thermal management is important during repeated daily charge and discharge cycles.

Polinovel uses liquid cooling at battery module level to help manage operating temperature. Combined with LFP battery technology and a standard 0.5C charge/discharge rate, the system is designed for regular commercial and industrial use.
