电动汽车中能量再生的主要原理是在降低速度时将驱动马达的功能改变为发电机。升降机使用相同的原理-放下升降机时，允许电动机作为发电机运行以产生电能并为电池充电。
该电气系统具有许多优点：

• •一次充电可进行更长的换档或多次换档操作

• •减少机械制动部件的磨损-再生电动机制动

• •降低能耗和相关的充电成本

The principal behind energy regeneration used in electric vehicles is to change the function of the drive motor to a generator when the velocity is reduced. The same principal is applied to the lift - when lowering the lift motor is allowed to operate as a generator creating electricity and charging the battery.
This electrical system shows a number of advantages:

• • longer shift or multiple shift operation on a single charge

• • wear reduction on mechanical brake components - regeneration motor braking

• • lower energy consumption and associated charging costs
