ELECTRICAL POWER SOURCE SYSTEM FOR VEHICLE Russian patent published in 2020 - IPC B60R16/33 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electric power source system for vehicle, which contains high-voltage battery, as well as first, second and third designs of electric power sources configured to be supplied with electric power from high-voltage accumulator. First design of the electric power source is connected to the first load, which includes an automatic driving system, the first DCDC-converter and the first battery. Second design of electric power source is connected to second load, including electronic control unit of steering control, electronic brake control unit, second DCDC-converter, second battery and information exchange unit made with possibility to exchange control information with automatic driving system. Third design of electric power source is connected to third load, including electronic control unit of steering control, electronic brake control unit, information exchange unit, connection controller and third battery. Connection controller is configured to control the connection state between the second DCDC converter and the third load, wherein the third battery is supplied with electrical power from the second DCDC converter.

EFFECT: creation of electric power source system, in which automatic driving system is protected against influence of voltage fluctuations generated in design of electric power source for onboard infrastructure.
