AI Technical Summary
Existing charging systems for electric vehicles with 800 V high-voltage power batteries are unable to directly utilize 500 V fast direct current charging piles, leading to charging difficulties and suboptimal user experience.
A charging system incorporating a motor control unit (MCU) with N bridge arms and an inductor that performs boost or buck conversion on the power supply voltage or battery voltage to adapt it to the power battery's charging voltage range, using a voltage conversion circuit to ensure effective charging.
The system enables charging of high-voltage power batteries by adjusting voltage levels to match the power battery's requirements, reducing system size and cost by utilizing a common MCU, and enhancing charging convenience.
