Method for contactlessly transmitting electrical energy to a load () using a transmission system (), having the steps of: converting alternating current from an alternating current source () into direct current using a primary rectifier (), converting the direct current generated by the primary rectifier () into alternating current using a primary inverter (), changing a primary parameter (di) at a component () of a primary part () of the transmission system, such that the electrical power consumed by a load () is changed as a result, contactlessly transmitting the electrical energy of the alternating current generated by the primary inverter () from a primary coil () to a secondary coil (), converting the alternating current generated in the secondary coil () into direct current using a secondary rectifier (), changing a secondary parameter at a component () of a secondary part () of the transmission system (), such that the electrical power consumed by the load () is changed as a result, supplying electrical energy as direct current to the load (), wherein an A-efficiency of the contactless transmission of energy with respect to a secondary A-parameter is determined, the secondary parameter is then changed from the secondary A-parameter to at least one secondary B-parameter and a B-efficiency is determined for the at least one secondary B-parameter, and that efficiency with the maximum efficiency is selected from the A-efficiency and from the at least one B-efficiency and this selected maximum efficiency is referred to as C-efficiency, and energy is then contactlessly transmitted with a secondary C-parameter assigned to the C-efficiency as an iteration step for determining the secondary C-parameter.

A starter for an internal combustion engine comprises a starter motor and a starter pinion which can be displaced transversely to the longitudinal axis of the motor. The starter pinion is rotatably mounted in an eccentric component which is connected in a rotationally fixed manner to a rotatable transmission component of a transmission that is disposed between the starter motor and the starter pinion.

A circuit arrangement for a data processing system is configured to process data in multiple modules. The circuit arrangement is configured to provide a clock as well as a time base and/or a base of at least one further physical quantity for each of the multiple modules. The circuit arrangement also comprises a central routing unit, which is connected to several of the multiple modules. Via the central routing unit, the modules can periodically exchange data based on the time base and/or on the base of the at least one further physical quantity. The several modules are configured to process data independently of and in parallel to other modules of the several modules.

The invention relates to a multi-stage charging device for a battery of a battery operated electrical motor. The multistage charging device comprises a buck converter, an intermediate circuit and a boost converter in order to generate a suitable direct charging current from a (one or three-phase) alternating current provided by a power connection. According to the invention, components of the electrical drive are used for the boost converter and the intermediate circuit: the electrical motor functions as an intermediate circuit and the drive converter functions as a boost converter. According to the invention, the coupling of the electrical motor to the network-side buck converter occurs so that at least half the charging current flows through at least one of the at least three coils of the electrical drive. The invention further relates to a corresponding method and to a corresponding use of the drive components.
