摘要
阐述了动力电池剩余电量的含义及影响电池剩余电量的因素,分析了动力电池剩余电量的常用估算方法:开路电压法、容量积分法、电池内阻法、模糊逻辑推理和神经网络法、卡尔曼滤波法的原理、优缺点和实际使用中的适用情况。
The meaning of the state of charge of the power battery and the factors affecting the state of charge of the battery are explained.The principles,advantages and disadvantages of common estimation methods(open circuit voltage method,capacity integral method,battery internal resistance method,fuzzy logic inference and neural network method,Kalman filter method)of the state of charge of power battery are analyzed,and their application in practical use.
