The Powertrain in EV Vehicles are responsible for delivering and managing electrical power to move a Vehicle.

The EV Power train consists of  below components and systems,

  1. Batter Packs (Lithium Ion Battery);
  2. Inverters or MCU(Motor Control Unit);
  3. E-drive (PMSM Motor);
  4. VCU(Vehicle Control Unit;
  5. i-PDU(Integrated Power Distribution Unit or All in one combo PDU);
  6. Mechanical Transmission (drive shafts, differential gears & EV axles );
  7. Thermal management systems ( Liquid Coolant Unit,Refrigerent Unit,Cabin air HVAC Unit).
