ENERGY SUPPLY DEVICE COMPRISING AT LEAST ONE CURRENT-DISCONNECTING ELEMENT

An energy supply device, in particular for a power tool, wherein the energy supply device includes at least one current-disconnecting element having a rated current-carrying capacity I_N, the rated current-carrying capacity I_N of the at least one current-disconnecting element being greater than a value of the following expression: 1000·(DCR_I){circumflex over (d)}−0.6, where DCR_I is the internal resistance of the energy supply device and is measured in accordance with standard IEC61960. A peak current-carrying capacity I_P of the at least one current-disconnecting element for a loading duration of at least 100 milliseconds can be greater than 3000·(DCR_I){circumflex over ( )}−0.6.
