Electric Vehicles Final Study Guide
Questions and Answers Latest Version
Graded A+
How does regenerative braking work in an electric vehicle?
✔✔Regenerative braking recovers kinetic energy during braking and converts it into electrical
energy, which is stored in the battery for later use.
What is the difference between an all-electric vehicle and a plug-in hybrid electric vehicle
(PHEV)?
✔✔An all-electric vehicle runs solely on electricity, while a plug-in hybrid electric vehicle has
both an electric motor and a gasoline engine, allowing it to run on electricity or fuel.
What is the typical range of most electric vehicles on a single charge?
✔✔The typical range of most electric vehicles is between 150 and 370 miles, depending on the
model and battery size.
How does an electric motor in an EV differ from an internal combustion engine (ICE)?
1
, ✔✔An electric motor uses electricity to generate rotational force, whereas an internal
combustion engine uses the combustion of fuel to create mechanical power.
What is the purpose of a DC fast charger for electric vehicles?
✔✔A DC fast charger provides high-speed charging to EVs, allowing them to recharge their
battery much faster than a standard home charger.
What type of power source is commonly used to charge an electric vehicle at home?
✔✔Electric vehicles are typically charged using a Level 2 AC charger, which requires a 240-volt
power supply.
What is an inverter's role in an electric vehicle?
✔✔An inverter converts the direct current (DC) from the battery into alternating current (AC) to
power the electric motor.
How does an electric vehicle (EV) reduce maintenance costs compared to traditional gasoline
vehicles?
✔✔Electric vehicles have fewer moving parts, no oil changes, and less wear on components like
the brakes due to regenerative braking, reducing overall maintenance costs.
