摘　　要：提出了基于析气影响和参数修正的修正型Gassing模型,并用Matlab/Simulink对该模型进行了仿真验证。验证结果表明,修正型Gassing模型也适用于电池充电临界情况,可以描述电池重要变量如SOC、温度和内阻等的动态特性,而且较之于原Gassing模型[1]进一步提高了模型的精度,使模型中SOC、内阻Ri等状态变量的计算更为合理和有效。Based on analysis of the influential factors on lithium battery system, a modified Gassing model is presented that considers the effect of Gassing and parameter modification and is verified by Matlab/Simulink. The simulation results show that the modified Gassing model can not only be well applied to battery charging critical conditions and reflect dynamic characteristics of internal resist- ance of cell and working temperature, but also improve the accuracy of the model, making SOC and other state variables＂ calculation more rational and valid than the Gassing model mentioned in refer- ence^3 .
