上海“双电”公交车再度探班

Second Field Research on a Line of New NewEnergy Public Bus in Shanghai

经过这一年的使用，各辆电动公交车的行驶里程均达到了5万km，可蓄电池的储电量也随之下降了20％左右，原来充一次电能跑3圈，现在只能勉强跑2圈了。

In 2013, reporter of <Commercial Vehicle> magazine once conducted a field research of Line 787—a new energy vehicle in Shanghai. This model of new energy bus has two electronicpower drive systems—one is super-capacitor, another battery, which was expected to be a promising market. One year later, reporter came to the Line 787 again, and learned that this two-E-drive systems are still working well, but truly there was minor issues to be solved.
