Method for regulating three-phase generator voltage in motor vehicle, involves providing reference voltage such that voltage value of open-circuit voltage corresponds to preset reference-load condition of energy storage

摘要

The method involves regulating a voltage (Ug) of a generator (20) to a voltage reference value during a driving condition is detected as a recuperation operation and to another voltage reference value when a driving condition is detected as a normal operation. The latter reference voltage is detected as a voltage value of an open-circuit voltage corresponding to a charge state level of an energy storage (30) i.e. battery. The latter reference voltage is provided such that the voltage value of the open-circuit voltage corresponds to a preset reference-load condition of the storage. An independent claim is also included for an arrangement for regulating a generator voltage in a motor vehicle.
