Great work, lots of Kona examples available from students to compare with. I'd also recommend working on this exercise with other types of e-vehicles like trucks, buses or even skateboards to get a sense of how things change with scale.

9) Any other interesting observations you'd like to share?
   The Hyundai Kona Electric uses the CCS charging standard, which consists of a combined AC and DC input port. The upper part of the inlet is for the Type 2 connector. This connector is used when charging at home or at fast AC points and fast points. The lower section below the Type 2 input carries high power during fast DC charging from a CCS connector.

The vehicle I have selected for the assignment is Hyundai KONA Electric
1.   Does your selected EV have on-board charging?
        Yes. The interface connector to On-board charger is having two options – J1772 connector and CCS combo. One is for AC charging and the other is
         for DC Fast Charging
2.   What is the rated AC input voltage of the on-board charger?
         Level 1 Charging 120 V AC, Level 2 Charging 240V AC
3.   What is the DC output voltage of the on-board charger?
        Around 355.2 V. I have considered that the DC output voltage of the On-board charger is same as the Battery pack nominal voltage
4.   What is the Battery pack nominal voltage?
        Around 355.2 V – Considering 96s3p type battery pack configuration with a nominal voltage of each cell is around 3.7 V
5.   What type of motor is connected?
         Permanent Magnet Synchronous motor (PMSM) with Max. Power of 136 PS and Max. Torque of 40.27 kg-m
6.   Is there an inverter needed in the drive unit? Yes
7.   Is there a high voltage DC-DC converter on-board the vehicle?
        No. Instead there is a Low Voltage DC-DC converter which is used for powering the 12 V system of the vehicle and it converts the battery pack
        voltage to 12 V
8.   What type of cooling methodology is used? - Passive air, active air, active liquid?
        Active Liquid Type Cooling
9.   Any other interesting observations you'd like to share?
        The vehicle can cover a range of about 406 km with a single charge
