Three cooling methods for power battery of new energy vehicles

The power battery is the core component of new energy vehicles, and the battery separator plays an important role in the power battery. It is mainly used to separate the positive and negative plates of the battery in a narrow space to prevent short circuit caused by the contact between the two electrodes, but it can ensure that ions in the electrolyte pass freely between the positive and negative plates. Therefore, the diaphragm has become the core material to ensure the safe and stable operation of lithium ion batteries.

The electrolyte will isolate the combustion source, the diaphragm will increase the heat resistance temperature, and the sufficient heat dissipation will reduce the battery temperature to avoid excessive heat accumulation, which will lead to the thermal runaway of the battery. If the battery temperature rises sharply to 300 ℃, even if the diaphragm does not melt and contract, the electrolyte itself, the electrolyte and the positive and negative electrodes will also undergo a strong chemical reaction, releasing gas, forming internal high pressure and explosion. Therefore, it is very important to adopt appropriate heat dissipation methods.
1.Air cooling structure of power battery pack
2.Power battery pack with liquid cooling structure
3.Natural convection heat dissipation mode of power battery pack

Trumony Aluminum Limitied, the battery thermal management expert , is committed to the design and development of liquid cooling, so we recommended you choose the power battery pack with liquid cooling structure
1. The heat of the battery is transferred to the liquid cooling pipe of the liquid cooling plate through the thermal conductive silicone pad, and the heat is taken away through the free circulating flow of coolant expansion and contraction, so that the temperature of the entire battery pack is uniform. The powerful specific heat capacity of the coolant absorbs the heat generated during the operation of the battery, so the entire battery pack can work at a safe temperature.
2. Thermal conductive silicone gasket has good insulation performance and high resilience, which can effectively avoid vibration, friction, damage and short circuit between batteries. It is the best auxiliary material for water cooling scheme.
