The increase in temperature causes a decrease in the internal resistance of the battery, and the battery efficiency increases. However, the temperature is increased, and the rate of harmful chemical reaction inside the battery is increased, thereby destroying the internal structure of the battery and affecting the life of the battery. Power cells are classified into cycle life and calendar life. Cycle life refers to the number of cycles a battery can perform before reaching the end of battery life condition, and in a specific experiment, each charge-discharge cycle has a certain charge and discharge regime and a certain charge and discharge end criterion. Calendar life is the length of time a battery can continue to perform some deterministic operation until it reaches an end-of-life condition. The influence of temperature on calendar life is great, and the calendar life is more seriously declined as the temperature is higher. Thus, after long-time accumulation, partial battery overcharge and discharge can be caused, the service life and the performance of the whole battery are further influenced, and potential safety hazards are caused.
