摘要
为解决动力电池欧姆内阻在线测量问题,实现动力电池健康状态监测及寿命预测,建立了氢镍动力电池二阶RC等效电路模型,提出了一种基于最小二乘法的混合动力车用氢镍动力电池欧姆内阻在线估算方法;通过台架试验及路试试验验证得出该在线估算方法的可行性,相对于现有的离线估算方法具有实用性与优越性。
To solve the problem of battery ohm resistance online measurement and monitor the state of health and lifetime prediction of nickel-metal hydride batteries,a second-order RC circuit model was built,and a ohm resistance online estimation method based on the least squares method was proposed.The bench test and the road test validated the feasibility of this ohm resistance online estimation method;compared with the existing off-line estimation method,the proposed method has Practicality and superiority.
