In order to make the batteries working in the allowable ambient temperature range, efficient battery thermal management systems should be put forward. In the current studies, three common heat management systems are used to control the thermal dissipation of batteries which are based on air cooling, water cooling and PCMs cooling.
The thermal dissipation mechanism of power batteries is analyzed in depth by studying the performance parameters of composite thermally conductive silicone materials, and BTM solutions and controllers for new energy vehicles are innovatively designed.
In recent years, with the rapid development of new energy vehicle technology, the performance of the battery thermal management system (BTMS) is crucial to ensure battery safety, life, and performance. In this context, researchers continue to explore new heat dissipation methods to improve the heat dissipation efficiency of battery modules.
The battery liquid cooling heat dissipation structure uses liquid, which carries away the heat generated by the battery through circulating flow, thereby achieving heat dissipation effect (Yi et al., 2022).
Discussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.
First, compared with traditional heat dissipation methods, CSGP has excellent thermal conductivity, which can quickly transfer the heat generated by the battery from the battery body to the heat dissipation area, effectively reducing the battery temperature.
