FIELD: transport.
SUBSTANCE: invention relates to vehicles with self-contained power sources and aims at producing electric power supply systems built around multiple power-controlled storage batteries. Proposed system comprises supply bus and voltage conversion units arranged between storage batteries and said bus. Voltage conversion units performs control in compliance with discharge current value and total value of tolerable charge power. Then system control unit drives defines higher tolerable and actual power values. Is actual power is smaller than total tolerable power, then said control unit drive controls conversion unit to make input/output voltage reach preset voltage magnitude. Note here that storage battery current reached also preset designed magnitude.
EFFECT: increased accuracy of control over storage battery power at their temperature lower than tolerable one.
