电池和电源网络可用作电动工业车辆的能源。电池概念定义了如何执行所需的电池均衡电荷。电池概念的选择取决于电池系统，使用时间，自动化程度和操作条件。电池概念包括可更换电池的操作和充电操作。这两个主要的电池概念通常称为充电类型。

        Battery and mains network are available as energy sources for electrically driven industrial trucks. The battery concept defines how the required equalising charges of the batteries are to be executed. The selection of the battery concept depends on battery system, usage time, degree of automation, and operating conditions. Battery concepts comprise the operation with exchangeable batteries and the charging operation. These two principal battery concepts are frequently called charge type.
