The high temperature effects will also lead to the performance degradation of the batteries, including the loss of capacity and power , , , .
For example, the heat generation inside the LIBs is correlated with the internal resistance. The increase of the internal temperature can lead to the drop of the battery resistance, and in turn affect the heat generation. The change of resistance will also affect the battery power.
It can be seen that as the abnormal heat generation rate increases, the range of thermal spread expands, and the influence on the maximum temperature of other normal batteries increases. When the abnormal heat generation rate is 500 W, the highest temperature of three batteries exceeds 70 °C. Figure 7.
The effect of abnormal heat generation location and abnormal heat generation rate on the maximum temperature difference of the battery at the end of discharge (ambient temperature = 25 °C). Generally, the performance and lifespan of the battery will be affected if the temperature difference inside the battery exceeds 5 °C.
Heat generation within the batteries is another considerable factor at high temperatures. With the stimulation of elevated temperature, the exothermic reactions are triggered and generate more heat, leading to the further increase of temperature. Such uncontrolled heat generation will result in thermal runaway.
Abnormal heat generation in the battery can lead to TR, so it is necessary to analyze the thermal behavior of the battery during abnormal heat generation. The main purpose of this paper is to control the maximum temperature of the battery module at less than 70 °C and the maximum temperature difference of the battery at less than 5 °C.

When the battery temperature exceeds 50°C (122°F), the charging process can be slowed down or stopped to prevent overheating, which can lead to a reduction in battery life. Lead acid batteries, on the other hand, are more tolerant of temperature extremes, but they still require special care when charging at high or low temperatures.
