为了获得MH-Ni电池等效电路模型中各主要参数的变化特性,在不同温度环境,针对MH-Ni电池的开路电压、迟滞电压、内阻等主要特性进行了试验测试研究。根据试验结果,建立了温度、电荷状态与电池各特性之间的变化关系。此外,还建立了MH-Ni电池的迟滞电压模型,通过试验获得了其主要参数的变化特性。最后,将试验结果与模型的计算结果进行了比较,验证了其准确性。

The Ni -MH battery characteristics including open -circuit voltage、hyteresis voltage and resistance were tested under different temperature conditions, which could be applied for the adjustment of the Ni-MH battery equivalent circuit model parameters. Besides, according to the test, the hyteresis voltage model and the major parameter characteristics were established. Finally, the model was verified by comparing the test with the model calculation result.
