System comprising a power tool and an energy supply device

Abstract

A system including a machine tool and a power supply device, the power supply device being provided for supplying the machine tool with electrical power. The power supply device can be detachably connected to the machine tool by means of an interface, the interface coincluding at least one female contact partner and one male contact partner. The interface has at least one elastic means for reducing a relative movement between the male contact partner and the female contact partner, the at least one elastic device for reducing the relative movement between the contact partners being designed to engage with the at least one male contact partner and/or the at least one female contact partner. The power supply device includes at least one energy storage cell, the at least one energy storage cell having an internal resistance DCR_I of less than 10 milliohm. Methods for connecting a power supply device to a machine tool via an interface, and to an interface itself are also provided. A power supply device for use in the system.
