However, the SOC has a higher influence on the internal resistance under low temperatures, because SOC affects the resistance value of the battery by influencing the disassembly and embedding speed of lithium ions in anode and cathode as well as the viscosity of electrolyte (Ahmed et al., 2015).
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.
Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.
The lower the temperature, the smaller the synergistic angle of the fluid field and the more consistent the synergistic effect at different flow rates and coolant temperatures. With an increase in cooling flow rate and a decrease in temperature, the heat exchange between the lithium-ion battery pack and the coolant gradually tends to balance.
In summary, the optimization of the battery liquid cooling system based on NSGA-Ⅱ algorithm solves the heat dissipation inside the battery pack and improves the performance and life of the battery.
