对接触网/电池混合电动车用车载锂离子电池的剩余电量(SOC)估算方法进行了论述。该方法能稳定估算SOC,并可自动调整电池容量和电池内阻等参数。采用运行试验的结果对这种估算方法进行了评定。
Remaining battery (SOC) estimation method of on-board lithium-ion battery for catenary / battery hybrid electric vehicle is discussed. The method can stably estimate the SOC, and can automatically adjust the battery capacity and battery resistance and other parameters. This method of estimation was assessed using the results of the run test.
