电容型镍氢动力电池采用稀土材料制成,具有寿命长、安全稳定并能快速充电等特点,即使遭受挤压、针刺、短路、加热、振动等情况也不会燃烧或爆炸,充放电3000次容量仅衰减2%。装配该电池的纯电动公交车在我国北方冬季严寒天气下能长期保持正常行驶。这为我国大面积推广电容型镍氢动力电池纯电动车奠定了坚实的基础。 Capacitor NiMH battery made of rare earth materials, with long life, safe and stable and can be quickly charged and so on, even subject to extrusion, acupuncture, short circuit, heating, vibration, etc. will not burn or explode, charge and discharge 3000 Secondary capacity only decays 2%. The pure electric bus equipped with the battery can keep its normal running for a long time under the winter cold weather in northern China. This has laid a solid foundation for the large-scale popularization of pure Ni-MH battery electric vehicles in our country.
