This series of products is specifically designed for the DC fast charging system of the BYD Qin PLUS (including DM-i super hybrid and EV pure electric versions), covering the complete high-voltage distribution and control system components from the charging port to the traction battery—the fast charging system parts assembly. As a core functional module of new energy vehicles, the DC fast charging system enables rapid replenishment at public charging stations, serving as a key system for ensuring charging convenience and user experience.

The BYD Qin PLUS fast charging system is centered around the high-voltage distribution unit (PDU) , integrating pre-charge circuits, current sensors, fuses, and other critical components. When a DC fast charger is connected, current flows through the PDU directly to charge the traction battery pack, with the entire process coordinated by the battery management system (BMS) and the charger via real-time CAN bus communication to ensure precise charging parameter matching [11†L3-L4]. In terms of safety control, the BMS monitors the charging gun connection status via the CC2 hardwire while controlling the DC charging contactor within the PDU to switch the current on and off, allowing the system to respond to abnormal conditions within 0.1 seconds and effectively prevent overcharging, short circuits, and other risks [11†L4-L5].

As a professional manufacturer of automotive high-voltage electrical parts, we develop and produce strictly according to BYD OEM technical standards, offering a full range of fast charging system components including the high-voltage distribution unit, DC charging contactors, DC charging interface, high-voltage wiring harnesses, and battery distribution unit. All products pass rigorous airtightness tests, withstand voltage tests, and salt spray tests, with OE numbers precisely matching the original vehicle for direct replacement of faulty or damaged original fast charging system components.
