At present, the multiple-in-one system is evolving from a mechanical structure integration to a deep integration of power electronics. Based on the existing VCU, users can integrate the other powertrain control modules (OBC DC/DC, BMS, traction inverter, and others) into a single controller—forming a power domain control platform. As one of the smaller subsystems, the charging inlet control system is flexibly integrate with others. In the future, trends toward this architecture are expected to increase due to increased demands for power density and volume in powertrains. To support this increased integration, the performance and capabilities of the main control MCU must increase, especially in memory, cores, and real-time processing.
