In addition, the paper simulate a parameter identification method which doesn't need no-load test to resolve the limitations of the method used by system. The result show that the method is feasible.

另外，针对于本文所采用辨识方法需要进行空载试验的局限性，还对一种不需要空载试验的参数离线辨识方法进行仿真试验，试验结果表明该方法可行。

Power-off memory function: All test data can't be lost when power cut. It can charge continuous re power-on and no need to set parameter and estate.

掉电记忆功能：掉电后所有测试数据不丢失，重新加电后无须设定参数和状态，可继续充电。
