IMI EV L3 Repair Practice Questions - IMI Level 3 Award Technical Specialist in Electric Hybrid Vehicle System Repair and Replacement Exam - IMI EV L3 Repair Practice Questions - IMI Level 3 Award Technical Specialist in Electric Hybrid Vehicle System Repair and Replacement Exam

Question 1

What is the primary role of the traction battery pack on an electric or plug-in hybrid vehicle?

Store high-voltage DC energy that supplies the inverter and traction motor under BMS control Generate three-phase AC directly for cabin HVAC blowers only Eliminate the need for any low-voltage electrical system on all designs Serve only as a mechanical inertia device with no electrical energy storage

Correct Answer:

Store high-voltage DC energy that supplies the inverter and traction motor under BMS control

Question 2

What does a battery management system (BMS) primarily monitor and control?

Only 12 V battery open-circuit voltage with no cell-level data Cell/module voltages, temperatures, state of charge/health limits, and contactor enable logic for pack protection Only ABS wheel-speed sensor outputs for stability control Only HVAC cabin blower PWM duty cycle

Correct Answer:

Cell/module voltages, temperatures, state of charge/health limits, and contactor enable logic for pack protection

Question 3

What is the main function of the HV contactors in a traction battery system?

Convert 12 V AC into grid-frequency three-phase power Measure tyre temperature during charging Galvanically connect or isolate the pack from the vehicle HV bus under BMS/ECU control Replace the need for orange cable identification

Correct Answer:

Galvanically connect or isolate the pack from the vehicle HV bus under BMS/ECU control

Question 4

What does the traction inverter primarily do?

Step 230 V AC workshop mains down to charge only the 12 V battery Provide the sole mechanical differential gearing for the axle Store kinetic energy as compressed air Convert pack DC into controlled motor excitation (typically three-phase) and manage regenerative energy return toward the pack

Correct Answer:

Convert pack DC into controlled motor excitation (typically three-phase) and manage regenerative energy return toward the pack

Question 5

What is a typical function of the DC-DC converter on an EV/HEV?

Step high-voltage DC down to support and charge the low-voltage (usually 12 V) system Increase tyre grip by modulating ABS only Replace the need for a BMS on every vehicle Isolate the vehicle from all OEM diagnostic tools

Correct Answer:

Step high-voltage DC down to support and charge the low-voltage (usually 12 V) system
