The ideal temperature range for a battery depends on its size, type, and electrochemistry characteristics. Manufacturers typically provide an optimal working range and a range of operating temperatures. For example, Lithium-ion batteries can operate between 20 °C to 40 °C, with their best performance at around 30 °C .
The target temperature (T tgt) of heating is often different, such as 60 °C , 29.1 °C , 10 °C , and 5.6 °C , which is determined by the performance of the battery , .
The temperature of the battery thermal management system changes in real time and can vary between −20 °C and 60 °C. The DP algorithm requires discrete state variables, and a relatively large range of temperature changes increases the number of grids, leading to an increase in computation time.
However, as the range of battery application scenarios continues to broaden, increasing attention has been drawn to their applicability and safety in a wide range of operating temperatures. Commercial LIBs typically operate optimally within a narrow temperature range of ∼15–35 °C .
When the battery temperature is above the desired temperature range, the radiator circuit is activated to cool the system (i.e., cooling mode). When the battery system temperature is in the desired temperature range, the pump remains on to equalize the temperature between the battery cells (i.e., temperature equalization mode).
Temperature variations can significantly influence the ionic transport in the electrolyte, thereby impacting the capacity, rate performance, and cycle stability of the battery.
