摘要
矿用电机车磷酸铁锂蓄电池的工作状态参数主要包括单体电池的工作电压、电流和温度。分别采用独立的模块对这3个量进行在线检测。电压检测部分再采用整体分布、部分集中的思路:将串联电池分成若干组,每组由电压检测模块集中检测。电压、电流和温度检测的模块化提高了检测系统的灵活性。通过试验验证该方法检测的数据准确。
Operating status parameters of LiFePO4 batteries in a mining electric locomotive includes the operating voltage,current and temperature of each cell in a set of battery,which are online detected by independent modules.The voltage detection used centralized/distributed detecting method.The modularization improved the system flexibility.The experimental results indicated that the collected voltage,current and temperature by this method were reliable.
