On-board electrical system for motor vehicle with several operating voltages has generator that charges one or more sub-batteries in series depending on revolution rate range

摘要

The system has two or more operating voltages and consists of two or more sub-batteries in series and a generator that charges one or more of these sub-batteries in series depending on the revolution rate range. The generator is switched to the maximum possible voltage depending on the charging voltage using a contact or switch and the stimulation is set to this voltage.
