| 摘要: |
| 由于电池内阻和极化现象的存在，锂电池在放电的瞬间会出现较大的电压跌落，高倍率脉冲放电锂电池更是如此。为了研究高倍率脉冲放电锂电池的功率输出特性，探讨温度、荷电状态和老化等因素对电池功率性能的影响规律，定义了锂电池的功率特性曲线，搭建了高倍率电池测试平台，并从温度、荷电状态和老化3个阻抗敏感因素开展实验研究。研究方法和结论对后期开展锂电池系统的峰值功率评估和功率曲线预测有一定的指导意义。 |

| Abstract: |
| Due to the existence of internal resistance and polarization, there will be a large voltage drop at the discharging moment of the lithium battery, especially the high-rate pulse-discharged lithium battery. The power characteristics of high-rate pulse-discharged lithium battery were studied, as well as the influence rules of temperature, state of charge and aging on battery power performance. The power characteristic curve of lithium battery was defined, a high-rate battery test plat-form was built, and experimental research was carried out from three impedance sensitive factors: temperature, state of charge and aging. The research methods and conclusions are of certain significance for the peak power evaluation and power curve prediction of lithium battery system. |
