The invention discloses a DCDC boost charging system and method based on a new energy automobile motor controller. The problems that in the prior art, a high-voltage platform architecture vehicle and a medium-voltage direct-current charging pile are difficult to match, and cost is high, weight is heavy and space is occupied due to the fact that a booster circuit is added are solved. The system comprises a fast charging interface, a driving charging controller and a battery manager, the fast charging interface is connected with the driving charging controller, the driving charging controller is in communication connection with the battery manager, and the battery manager is in communication connection with the fast charging interface. The driving charging controller comprises a third change-over switch, a battery and a permanent magnet motor, when the driving charging controller works in a boost charging mode, the third change-over switch is controlled to be switched on, the three-phase full-bridge inverter upper bridge is controlled to be switched off, and an upper bridge fly-wheel diode, a lower bridge and a permanent magnet motor three-phase inductor jointly form an equivalent direct current boost circuit; and the DCDC boosting and quick charging function of the high-voltage platform architecture vehicle is realized.
