摘要： PROBLEM TO BE SOLVED: To maintain a continuously available state, while ensuring the life of a battery pack.SOLUTION: As shown on Fig. 3(b), an effective current is reduced in a low temperature region thus reducing the voltage drop in a low temperature region. When the temperature rise subsequently to bring about a normal temperature region, the effective current is increased so that a motor 101 can be rotated more strongly. In the normal temperature region, overdischarge is never recognized because internal resistance decreases and thereby the voltage drop decreases. Consequently, the temperature further rises to TP, and a high temperature region is reached. As shown on Fig. 3(b), the effective current decreases again in this region.
摘要翻译：要解决的问题：为了保持连续可用状态，同时确保电池组的寿命。解决方案：如图1所示。如图3（b）所示，在低温区域有效电流降低，降低了低温区域的电压降。当随后温度升高达到正常温度区域时，有效电流增加，使得马达101能够更强烈地旋转。在正常温度区域，由于内部电阻降低，电压降降低，因此不会识别过放电。因此，温度进一步上升到TP，达到高温区域。如图所示。如图3（b）所示，该区域的有效电流再次下降。
