Simply put, the working principle of the liquid-cooling unit for power batteries is as follows: First, the coolant— a 50% VV ethylene glycol aqueous solution—is circulated through pipes around the battery pack, absorbing heat. Then, after passing through a heat exchanger, the coolant transfers this heat to the external environment, effectively reducing the battery temperature. This design significantly enhances both the efficiency and safety of the battery system.
Power batteries generate heat during operation; excessively high temperatures can not only affect battery performance but may even pose safety risks. Battery Liquid Cooling Unit It emerged precisely within this context, utilizing circulating liquid to absorb and dissipate heat, thereby keeping the battery's operating temperature within safe limits.
Simply put, the working principle of the liquid-cooling unit for power batteries is as follows: First, the coolant—specifically a 50% VV ethylene glycol water solution—is circulated through pipes around the battery pack, absorbing heat. Then, after passing through a heat exchanger, the coolant transfers this absorbed heat to the external environment, effectively reducing the battery temperature. This design significantly enhances both the efficiency and safety of the battery system.
