Analysis of the "Three Electrics" Technology of New Energy Vehicles

The "small three electrics" in new energy vehicles, namely the high-voltage power distribution unit (PDU), on-board charger (OBC) and DC/DC converter, are key components in addition to the "big three electrics" (power battery, motor, and electronic control). They play an important role in energy conversion and transmission in new energy vehicles. The PDU is responsible for the high-voltage electrical distribution of the entire vehicle, the OBC is responsible for converting external AC power into DC power to charge the battery, and the DC/DC converter is responsible for converting the high-voltage DC power of the battery pack into low-voltage DC power to power other electrical components in the vehicle.
