Week-6 Challenge: EV Drivetrain

Q1

• DC-DC Converters (Chopper): These converters are used to regulate the voltage level between the traction battery and the various vehicle systems, such as the 12V battery or other accessories.
• AC-DC Converters(Rectifier): These converters are used to charge the traction battery from an external AC power source, such as a home charging station or public charging station.
• DC-AC Inverters (Inverter): These converters are used to transform the DC power from the traction battery into AC power for driving the electric motor.

Q4

The author, Wally Rippel, provides a thorough analysis of two key technologies used in electric vehicle drives, specifically focusing on DC brushless drives and induction drives. He discusses their respective construction, working principles, and the differences in their performances. Overall, the author presents an unbiased perspective, outlining the advantages and limitations of both technologies. He also suggests that both types of machines are likely to coexist in the future, with each having its niche in the market.
