METHOD OF CONTROLLING POWER SUPPLY OF VEHICLE AND VEHICLE POWER SUPPLY CONTROL DEVICE Russian patent published in 2019 - IPC B60R16/33 H02J7/14 H02J7/34 B60L58/12 

FIELD: machine building.

SUBSTANCE: group of inventions relates to electric circuits for vehicles. Method of vehicle power supply control consists in the following. When constant voltage of the power supply circuit is required, determining whether the required non-varying voltage can be achieved when the secondary storage battery is connected to the power supply circuit, depending on required invariable voltage, current output to power circuit by means of power generator, and charge state of secondary storage battery. Secondary accumulator battery is connected to the power supply circuit when it is determined that the required non-varying voltage can be achieved. Secondary accumulator battery is disconnected from the power supply circuit when it is determined that the required non-varying voltage can not be achieved. Secondary storage battery has a lower internal resistance than the primary storage battery. Also disclosed is vehicle power supply control device.

EFFECT: possibility of stably supplying the required non-varying voltage.
