FIELD: transportation; electricity.
SUBSTANCE: group of inventions relates to electrical traction systems of vehicles. Electric accumulator comprises an energy accumulator, a converter and an intermediate circuit of the power supply source. Energy accumulator is configured to be connected through an inverter to an intermediate circuit. Besides, the converter contains a support container and several connected in parallel support tank of controlled circuits. Besides, converter phase tap is connected to each converter circuit. Besides, the energy accumulator is connected to one first phase of the converter, and the intermediate circuit is connected to the second phase of the converter, which differs from the first phase of the converter. Also disclosed is a method of operating a power accumulator.
EFFECT: technical result consists in possibility of flexible operation of energy accumulating device with networks of any or varying voltages.
