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

摘要

In 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 by a rope starter, a voltage source is provided that generates electric energy electro-dynamically or photovoltaically before starting the internal combustion engine. The thus generated electric energy is stored in a rechargeable energy storage device arranged within the power tool. The electric energy stored in the energy storage device is supplied to the engine control unit upon first rope starter pull for start of the internal combustion engine. The device for performing the method has an electro-dynamic or photovoltaic voltage source and 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.

主权项

1. 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, prior to a first rope starter pull being carried out, 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.
