摘要
研制了新型的电动汽车蓄电池组管理系统,该系统在提高采集监测电流、电压、温度等信号精度的基础上,采用了放电率、温度、自放电及容量老化等补偿的安时积分模型的估计,并考虑了自调整,从而可以以较高的精度预测电动汽车的电池荷电状态(SOC).
This paper introduces a new type of battery management system (BMS) for Ni-MH batteries in hybrid electric vehicles. On the basis of improving the measurement of parameters such as current, voltage and temperature, the system can estimate the state of charge (SOC) of the batteries with high precision by adopting the ampere-hour model with compensation in charge-discharge rate, temperature, self-discharge, aging and the consideration of self-adjustment.
