1.Three Major Components (core power system)
Power battery: Stores high-voltage electricity, accounts for 30%-40% of vehicle cost.
Traction motor: Converts electric energy into mechanical power to drive wheels.
Motor Control Unit (MCU): Realizes AC-DC conversion and regulates motor torque and speed.
2.Three Minor Components (auxiliary high-voltage system)
On-Board Charger (OBC): Converts household AC power to DC for battery charging.
DC-DC Converter: Steps down high battery voltage to 12V low voltage for infotainment, lights and meters.
Power Distribution Unit (PDU): Distributes high-voltage power to heat pumps, air conditioners and chargers
