VEHICLE ON-BOARD NETWORK VOLTAGE SUPPLY METHOD Russian patent published in 2020 - IPC B60R16/03 B60R16/33 H02J7/14 

FIELD: machine building.

SUBSTANCE: invention relates to automotive electrical equipment. In the vehicle on-board network voltage supply method, in the motion mode the first partial network is supplied with voltage from the second partial network through the first constant voltage converter. First energy accumulator is used to cover load peaks. In motionless mode, the first partial network is supplied with voltage by means of the first accumulator. Recharging first battery with energy from second accumulator in motionless mode. Recharging of the first accumulator is carried out periodically and/or when the controlled parameter, which is a measure for state of charge of the first energy accumulator, indicates fall below the specified minimum state of charge of the first accumulator. In order to recharge the first accumulator in motionless mode, the first constant voltage converter and the second partial network are activated for the recharging process.

EFFECT: network supply is improved.
