What materials are used for batteries cooling?

  It is best to use thermal conductive phase change materials for battery thermal cooling, phase change of thermal conductivity is a kind of material that can absorb and release latent heat of phase change, which has important applications in energy storage. Phase change materials used in heat pipe power system of power battery have been paid more and more attention.

  The thermal management technology of automotive batteries using phase change materials with thermal conductivity has been widely studied. Using latent heat of phase change materials to control the temperature of batteries can effectively reduce the temperature rise of batteries under high operating conditions and improve the temperature uniformity.

  The enthalpy of phase transition is used to absorb heat without significant change in its own temperature. Thermal conductive phase change materials are used in aerospace, building energy saving, solar energy utilization, cold chain transportation and other fields. In the application case of battery thermal management, the advantages and disadvantages of air cooling, liquid cooling and phase change temperature control methods are compared. Thermal conductive phase change materials (PCM) have attracted much attention due to their excellent performance, high reliability and low cost.

  In general, the thermal solution of batteries requires that the maximum temperature not exceed the operating temperature and the temperature be uniform. To ensure that batteries perform well and prolong their service life, you need to optimize the structure of batteries, add heat dissipation facilities, and control the temperature environment in which batteries operating.
