HV ELECTRICAL SYSTEM 16 COMPONENT DETAILS A. High Voltage Battery (lithium - ion) - 40.5 kWh Lithium Ion Battery Pack An on board high voltage electrical energy storage device. B. 3in1 Unit Assy i. DC – DC Converter A device that converts HV DC power from the HV battery to LV DC power which is required to maintain LV battery charge, which in turn powers the LV systems like lights, wipers, infotainment, etc. in the vehicle. ii. Power Distribution Unit Distributes power from the high voltage battery to the HV components like inverter, DC-DC converter, Ecompressor etc. iii. On-Board Charger (OBC) - 6.6 kW A device that charges the high voltage battery by converting AC power from a domestic supply into DC power and supplying it to the battery. C. Motor Control Unit A device to control traction motor. D. High Voltage Cable Use for high voltage electrical energy. E. Charging Port Provided for charging purpose. F. Cable HV AC Charging Gun Provided for charging purpose. G. Traction Motor - 105 kW (136PS) A device that converts electrical energy into rotational mechanical energy, which is then transfer as rotational torque to the wheels through the gearbox. NOTE: 3in1 Unit Assy includes OBC, DCDC converter and PDU in a single unit and the functionality of each unit is same as mentioned above.
