What is a liquid cooling system?

The integrated frequency conversion liquid cooling system helps limit the temperature difference among cells within 3 ℃, which also contributes to its long service life. It has a nominal capacity of 372.7 kWh with a floor space of just 1.69 square meters. The system is suitable for inverters with operating voltages ranging from 600 to 1500 volts.

How many temperature detectors does a battery module have?

Each battery module has 8 temperature detectors. There are 2 racks that fit in a single battery cabinet, 9 slots in each battery rack to accommodate 8 battery modules and total 1 BSPU (Battery Switch & Protective Unit). Racks are connected in parallel and paired with a system BMS to meet the power and energy requirements of the application at hand.

How does a battery cooling pump work?

Working principle of Liquid Cooling Battery Cooling: Cooling liquid powered by the pump will circulate inside battery modules and take the heat from batteries. When the liquid gets out of the battery modules, it became hot liquid with the heat from batteries. The hot liquid will circle back to a heat exchanging tank.

How many battery cells are in a battery rack?

All wire connections are placed on the front side of the rack to allow easy installation and maintenance. Since each battery rack hosts 8 battery modules and each battery module has 52 battery cells, each battery Rack has a total of 416 battery cells connected in series.

What is a battery module made of?

The external casing is made of metal covered by insulating materials. For example, the top cover is made of PP, the bottom base is made of aluminum. The copper bars and screws are connected internally to prevent short circuit to ensure the electrical safety of the battery module. Each battery module has 8 temperature detectors.
