The industrial truck has two voltage sources with respective serially-connected batteries (10,12) and serially-connected capacitors (C1-C4). The balancing units of voltage sources, balance unequal active voltages of batteries and capacitors, during each operating state of the truck, respectively. The balancing units include inductive transmitters (30,130) to which battery and capacitor circuits (20,22,120-123) are inductively coupled. |
