废旧汽车三元锂电池安全放电影响因素探究
|
摘要
随着电动汽车市场的推广,废旧动力电池回收处理问题引起了广泛关注。动力电池有较大的电容量,因此其体积较一般电池的体积大上数倍。由于废旧动力电池仍存有剩余电量,使其不能立即安全处理。因此,释放废旧动力电池中的剩余电量对其后续处理十分重要,如进行拆解、破碎等操作。探究了汽车三元动力锂电池的负载放电以及影响放电时长的因素,为更好地释放电能提供有效的数据支持。结果表明,大电流高电压放电能有效缩短放电时间。
Driven by the electric vehicle markets, many power batteries will be wasted. The problem of recycling waste power battery attracts people's attention. For the large capacity, the volume of a power battery is larger than normal cell by several times. There is still remaining power which makes the spent power battery unsafe for the immediate treatment. So it is very important to release the remaining power of spent power battery for its subsequent processing, such as dismantling, crushing and so on. The vehicles ternary lithium battery discharge load was explored by testing how different current and voltage effected on the discharge time of the power battery. The results showed that the heavy current and high voltage discharge could effectively reduce discharge time.
