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.
The performance of liquid cooling methods is constrained by the low thermal conductivity of the coolants, especially under high charging and discharging conditions. To enhance the effectiveness of battery thermal management systems (BTMSs), it is crucial to utilize fluids with improved thermal conductivity.
Thermal management of lead-acid batteries includes heat dissipation at high-temperature conditions (similar to other batteries) and thermal insulation at low-temperature conditions due to significant performance deterioration.
The research outcomes indicated that the heat dissipation efficiency, reliability, and optimization speed of the liquid cooled heat dissipation structure optimization method for vehicle mounted energy storage batteries based on NSGA-II were 0.78, 0.76, 0.82, 0.86, and 0.79, respectively, which were higher than those of other methods.
