Abstract
A system including a power tool and an energy supply device, wherein the energy supply device is provided for supplying the power tool with electrical energy. The energy supply device can be releasably connected to the power tool via an interface, wherein the interface includes at least a female contact partner and a male contact partner. The female contact partner and the male contact partner are in contact with each other in at least a first contact region and in a second contact region. The first contact region may be defined by a first contact normal force, while the second contact region may be defined by a second contact normal force, wherein the first contact normal force and the second contact normal force have different orientations. In addition, the interface can include an elastic means for reducing the relative movement between the male contact partner and the female contact partner. An interface for transmitting electrical energy, and to an energy supply device is also provided.
