The invention relates to a device for supplying electrical energy to an electro-pen (2) with an electric drive unit for driving a tool. The device comprises a console with an energy supply unit (1) which supplies the electric drive unit of the electro pen (2) with electrical energy. Said console with the energy supply unit (1) is equipped with an accumulator (4). The electrical energy supply from the console with the energy supply unit (1) to the electro-pen (2) takes place either via a sterilisable cable or inductively without an electrical connection. The console with the energy supply unit (1) is configured in such a way that it can be steam-sterilised. The device is mobile since it is not physically connected to a mains supply or a console. Sterility is also guaranteed.
