通过电池电流为工业车辆驱动器提供能量。区别在于纯电池操作和允许切换到其他驱动器类型的开关操作。开关操作的构造类型为混合驱动以及主电源和电池电流的组合使用。例如，在机架过道中操作时，可从高架式叉车向市电供电，而在过渡（末端过道）区域中，在过道中操作时，可从电池向蓄电池供电。

         Energy supply for industrial truck drives via battery current. To be distinguished are the pure battery operation and the switch operation which allows the switchover to another drive type. Construction types of switch operation are the hybrid drive as well as the combined use of mains and battery current. For example, a high rack lift truck can be supplied with current from mains while operating in the rack aisle and from the battery while operating outside the aisle in the staging (end-aisle) area.
