FIELD: transport.
SUBSTANCE: invention relates to electric power supply for hybrid vehicles. Proposed device comprises first power supply, second power supply, electrical load, control device and diagnostics hardware. Note here that control device comprises first voltage conversion control device, diagnostics inhibit device to inhibit diagnostics in compliance with voltage check values equal to first voltage, device to control starting the engine at low temperature, second voltage conversion control device by setting check voltage equal to second voltage and device to permit starting of motion. Proposed method consists in that check voltage is set equal to first voltage. Diagnostics device operation is inhibited. Voltage converter is feed-back controlled. Motor excitation is controlled. Voltage converter is feed-back controlled by setting check voltage equal to second voltage. Diagnostics device operation inhibition is cancelled. Hybrid vehicle start is indicated.
EFFECT: reliable starting of hybrid vehicle engine.
