FIELD: electricity.
SUBSTANCE: invention is related to charge of accumulator batteries of hybrid automobiles. Accumulator batteries charging system for hybrid electrical transportation vehicle comprises high-voltage battery; generator; voltage converter; low-voltage battery and charging generator with drive from power unit. The system includes a control unit, which measures charge state of high-voltage battery; energy flow from generator to high-voltage battery or from high-voltage battery to traction engine. Control unit regulates low voltage of voltage converter so that it is higher than voltage provided by charging generator at high charging level of high-voltage battery or when energy is supplied to high-voltage battery. Control unit also regulates low voltage of voltage converter so that it is lower than voltage provided by charging generator at low charging level of high-voltage battery or when energy is transmitted from high-voltage battery.
EFFECT: increased operational life of high-voltage battery.
