摘要：

In order to study the inconsistency and uneven behavior of temperature in lithium-ion batteries packing, based on the electrochemical-thermal coupling model, this paper takes eight pouch batteries as an example, establishes different circuit modules through different series and parallel connection modes, and analyzes the temperature characteristics and inconsistency of batteries at the discharge of 1C and 0.5C. The results show that the inconsistency and temperature difference of the battery module are related to the discharge rate. The increase of parallel branches or the decrease of the number of series units will not only reduce the average temperature rise and maximum temperature difference of battery module, but also affect the temperature rise rate and voltage at the end of discharge. When the number of parallel branches is the same, the consistency of the series-parallel modules is better than that of parallel-series modules. For the parallel-series modules, the more batteries are connected in series in the parallel branch, the worse the consistency of the batteries is. For the series-parallel modules, the more the number of parallel branches, the worse the battery consistency. © 2022, Editorial Board of JBUAA. All right reserved.
