LIBs as a complicated electrochemical energy storage system will produce a lot of heat during the operating process, especially on high rate charge/discharge processes [17, 18]. In Zhang’s study, the temperature of a NMC battery will exceed 75 °C at a 3 °C discharging rate without any treatment (ambient temperature is 25 °C) .
The optimal operating temperature range for these power batteries was found to be between 25–40 °C, and the ideal temperature distribution between batteries in the battery pack should be below 5 °C . Sato pointed out that when the battery temperature is higher than 50 °C, the charging speed, efficiency, and lifespan are reduced.
At a voltage of 3.4 V, the cPCM could heat up an eight-cell module at a rate of 13.4 °C/min, as shown in Fig. 16, with a maximum temperature difference of 3.3°C between cells. Moreover, during high- rate discharge (3 C), cPCM can also reduce the battery temperature from 77°C to 43°C.
Also, temperature uniformity is crucial for efficient and safe battery thermal management. Temperature variations can lead to performance issues, reduced lifespan, and even safety risks such as thermal runaway. Uniformity in temperatures within battery thermal management systems is crucial for several reasons: 1.
Battery temperatures were effectively controlled below 50 °C, and temperature differences were maintained below 5 °C, demonstrating that heat pipes were a reliable thermal management solution for power batteries in EVs under various operating conditions .
When integrated into the BTMS, the PCM successfully limited the battery’s surface peak temperature to 48.76 °C and the maximum temperature differential to 4.07 °C at a discharge rate of 6C.
