电动工业车辆的最早驱动控制类型。通过分别连接电阻和断开电阻来逐步控制电源。缺点是，电阻吸收的部分功率会转化为热量，因此会损失能量。使用分体式电池可以降低能耗。对于这种方法，两半电池并联连接以降低能量需求，而串联连接则满足高能量需求。因此，为了降低能量需求而降低了电池电压，降低了能量输出，并且也降低了热转化的必要性。

        Oldest type of drive control of electrically driven industrial trucks. Power is controlled in steps by connection respectively disconnecting resistors. The disadvantage is the fact that the part of the power that is absorbed by the resistors is transformed into heat and thus this energy is lost. Energy consumption can be reduced by using a split battery. For this method the battery halves are connected in parallel for lowenergy demand and in series for high energy demand. Thus the battery voltage is reduced for low energy demand, the energy output is reduced, and the necessity for heat transformation is also reduced.
