CAE EV Technology & Future Trends 1

Question 1

What is the primary difference between a BEV and a PHEV?

Accepted Answer

BEVs run entirely on battery power; PHEVs have both a battery and an internal combustion engine

Answer

BEVs are faster than PHEVs

Answer

PHEVs have larger batteries than BEVs

Answer

BEVs use hydrogen fuel cells

Question 2

What does kWh measure in electric vehicle batteries?

Accepted Answer

Kilowatt-hours, the total energy storage capacity of the battery

Answer

The maximum speed of the vehicle

Answer

The charging voltage required

Answer

The battery's physical weight

Question 3

What is DC fast charging and how does it differ from Level 2 charging?

Accepted Answer

DC fast charging bypasses the vehicle's onboard charger to deliver high-power direct current, charging much faster than Level 2 AC charging

Answer

DC is slower but safer than Level 2

Answer

They charge at the same speed but use different plugs

Answer

DC fast charging only works at home
