Abstract
The present invention relates to a vehicle battery module comprising a power conversion device and a three-phase vehicle battery system formed from a plurality of vehicle battery modules. The vehicle battery module comprises a battery, a DC / DC converter, and a three-phase AC unit for outputting a three-phase AC module voltage. The three-phase vehicle battery system comprises: a DC system output terminal, which includes a plurality of vehicle battery modules and is formed by connecting the DC module output terminals contained in each of the plurality of vehicle battery modules in parallel; and a three-phase AC system output terminal, which is formed by connecting the three-phase AC module outputs contained in the plurality of vehicle battery modules in series, phase by phase.
