Method and device for providing electric energy for an engine control unit

A device for providing electric energy for an engine control unit before start of an internal combustion engine that is to be started by a rope starter, the device comprising:

• a voltage source;
• an energy storage device electrically conductingly connected to the voltage source;
• wherein the energy storage device has an output that is electrically conductingly connected to the engine control unit to supply electric energy to the engine control unit;
• wherein the voltage source is coupled to a mechanical drive action adapted to be driven by an operator and the mechanical drive action is driven by the operator to generate electric energy by the voltage source prior to a first rope starter pull being carried out.

A method for providing in a hand-held power tool electric energy for an engine control unit before start of an internal combustion engine of the power tool that is to be started mechanically by a rope starter, the method comprising the steps of

• providing a voltage source as a voltage supply for the engine control unit, wherein the voltage source provides electric energy for operating the internal combustion engine and wherein the voltage source is driven by a mechanical drive action;
• an operator driving the mechanical drive action by a translatory movement to generate electric energy by the voltage source before start of the internal combustion engine;
• storing the electric energy generated by the voltage source in a rechargeable energy storage device arranged within the power tool;
• and
• supplying the electric energy stored in the energy storage device to the engine control unit upon carrying out the first rope starter pull for starting the internal combustion engine.
