基于析气现象和热力学原理对锂电池系统在临界和非临界情况下的动力学特性进行了较为细致的研究,建立了以荷电状态(SOC,State of Charge)、温度、开路电压和内阻为状态变量的系统动力学模型并应用Matlab/Simulink软件实现了相应的动态仿真.仿真结果表明,该模型不仅能反映锂电池在非临界情况下的动力学特性,而且在一定程度上还能较为准确地描述临界情况的非线性动力学特性.

Based on gassing phenomenon and thermodynamics, the dynamic characteristics of a Li-ion battery system under critical and non-critical situations were investigated. A dynamical model of battery system was established with SOC (State of Charge), temperature, intemal resistance and open circuit voltage as the state variables and the corresponding dynamic simulations were carded out by Matlab/Simulink. The simulated results show that the model is suitable for both non-critical and critical situations of Li-ion battery.
