Zusammenfassung:	The invention relates to a BOOST power supply conversion method and system based on an electric drive system, and the method comprises the steps: a charging pile releases a charging current, and the current enters a motor system through a PDU system; the current flows out of the motor system and enters the motor controller system, and the motor controller system carries out BOOST boosting on the current; the boosted current enters the battery for charging; the current in the battery flows back to the charging pile to realize a closed loop. The system comprises a charging pile, a PDU system, a motor system, a motor controller system and a battery, and the motor system is used for realizing BOOST. According to the invention, the three-phase staggered BOOST circuit is successfully applied to the 400V charging pile and the 800V battery, an existing motor controller platform is shared, BOOST loop control and function protection are completed, the charging efficiency is relatively high, and the actually measured fu
