With BYD’s soaring market volume, repair shops frequently encounter tough troubleshooting scenarios. Reference materials for newly-released models are scarce. There are major configuration differences among DM-i, EV, Champion Edition and Honor Edition variants. Online high-voltage circuit diagrams for new energy vehicles are messy and error-prone, which can easily lead to mistakes during maintenance.

From the early Yuan EV and Tang DM to the latest Yuan UP, Tang L and BYD Xia, repair priorities vary greatly between different model years and configurations. Especially for core three-electric components including BMS battery management systems, VCU vehicle control units, motor controllers and high-voltage battery packs, the lack of standardized reference documents not only reduces maintenance efficiency, but also brings potential safety hazards during high-voltage operations.
