Textbook Problem

While discussing controllers in BEVs: Technician A says the controller may reverse the current flow to the motor when reverse gear is selected. Technician B says modern controllers adjust motor speed through pulse width modulation. Who is correct?

a. Technician A only

b. Technician B only

c. Both A and B

d. Neither A nor B

To determine

Technician with correct approach.

Explanation

Given information:

While discussing controllers in BEVs:

Technician A says the controller may reverse the current flow to the motor when reverse gear is selected.

Technician B says modern controllers adjust motor speed through pulse width modulation.

Battery electric vehicle (BEVs) has successfully achieved energy by using an electric machine from propulsion electric source. In the automobile industry, electric vehicle has proved to be environment-friendly as it does not burn fuel to run an engine. Hydrogen is used as a source of energy in fuel cells. It is used as fuel for running electric vehicles. It is present in the form of a compound, for example, hydrogen and oxygen combine to form water. Fuel cells used in electric vehicles use hydrogen for source of energy. Fuel injector is used to inject hydrogen into fuel cells for generation of electricity. Regenerative braking helps in recovering the lost kinetic energy. This energy is used to recharge the battery of hybrid vehicles. A 12-volt auxiliary system is necessary because it helps in providing a suitable voltage to run the engine...
