Quizplus · Accepted Answer

Technician A is correct because MG1 is used as a generator during regenerative braking and deceleration to convert kinetic energy into electrical energy and charge the battery. Technician B is also correct because MG2 is used as an electric motor to drive the wheels and provide propulsion, as well as working as a generator during regenerative braking to convert some of the kinetic energy back into electrical energy.
