【摘要】 动力电池是电动汽车的动力来源。随着电动汽车的推广,动力电池也进入蓬勃发展阶段。随后的几年内将会出现大量难以满足电动汽车要求的动力电池。因此,对动力电池进行梯次利用具有重要意义。首先介绍了国内外发展现状,详细分析了梯次利用关键技术与意义,最后对动力电池梯次利用进行总结并提出展望。更多还原

【Abstract】 Power battery is the source of electric vehicle. With the promotion of electric vehicle, power battery has also entered a vigorous development stage. In the next few years, there will be a large number of power batteries that are difficult to meet the requirements. Therefore, the echelon use of power battery is of great significance. Firstly, the development status of battery echelon use were introduced, then the key technologies and significance of echelon use were analyzed in detail. Finally, the echelon use of power battery was summarized, and the prospects were put forward.更多还原
