What is the primary function of the inverter in an electric vehicle?
The inverter converts DC power from the battery into AC power to drive the electric motor.
Which component regulates the flow of electricity in an EV powertrain?
The controller manages power delivery from the battery to the motor, ensuring optimal efficiency and performance.
What does regenerative braking do in electric vehicles?
It captures kinetic energy during braking and converts it back into electrical energy stored in the battery.
Which type of motor is commonly used in EVs for high efficiency?
Permanent Magnet Synchronous Motors (PMSMs) are widely used in EVs for their efficiency and performance.
Why is thermal management critical in EV powertrains?
It prevents overheating of components like the motor, inverter, and battery, ensuring safe and efficient operation.
What is the function of a DC-DC converter in EVs?
It steps down high-voltage DC from the battery to lower voltage for auxiliary systems.
