SUBSTANCE: invention is related to power supply units of vehicles. The device and method are suggested for compensation of electric load power in a vehicle by means of a capacitor with high capacitance. The capacitor with high capacitance discharges current rapidly in order to compensate power when voltage at the generator and accumulator output drops temporarily during motion of the vehicle, and the capacitor is charged by permanent power pulse in order to prevent instability of the accumulator voltage in result of the generator overload taking place when the capacitor is charged. Charge of the capacitor is stopped temporarily and it discharges current to compensate power of the electrical load if voltage drops at the accumulator battery terminals in result of electrical load at the charged capacitor thus leading to compensation of power supply instability, e.g. voltage drop, in real time mode.

EFFECT: increase in the vehicle power and prevention of temporary deceleration thus improving control characteristics for the vehicle, improving efficiency factor significantly, operational performance in regard to fuel and longer operational life of different electrical parts.
