AARC - Accredited Automotive Recycler EV & Hybrid Vehicle Processing Questions and Answers

Question 1

A technician is preparing to depower a hybrid vehicle's high-voltage system. In addition to standard PPE, which piece of equipment is essential for protection against electrical shock?

Accepted Answer

Class 0 insulated gloves

Answer

Class 0 insulated gloves are rated for up to 1,000 volts and are the industry standard for protecting technicians from the high-voltage systems in hybrid and electric vehicles. The other items are standard PPE but do not offer specific protection from high-voltage shock.

Question 2

An auto recycling facility receives a wrecked EV with visible damage to the high-voltage lithium-ion battery casing. What is the appropriate initial action for storing the vehicle?

Accepted Answer

Move the vehicle to a designated quarantine area at least 50 feet away from other vehicles and structures.

Answer

Damaged lithium-ion batteries pose a significant fire risk due to potential thermal runaway, which can be delayed. Best practices require isolating the vehicle in a designated quarantine area, maintaining a safe distance (often cited as 50 feet) from other flammable materials, vehicles, and buildings.

Question 3

When inspecting an end-of-life hybrid vehicle, which of the following is the standard visual indicator used by manufacturers to identify high-voltage cables and components?

Accepted Answer

Bright orange sheathing or conduit

Answer

Industry safety standards, such as ISO 6469-3, mandate that high-voltage cables, connectors, and component housings in electric and hybrid vehicles are colored bright orange to serve as a clear visual warning to technicians and emergency responders.

Question 4

After disabling the high-voltage system in an EV by removing the service disconnect, what is the critical next step a technician must perform before starting any dismantling work on the high-voltage components?

Accepted Answer

Wait for a minimum of 10-15 minutes for the system's capacitors to discharge.

Answer

High-voltage systems contain capacitors that can store a lethal electrical charge even after the battery is disconnected. Technicians must wait for a manufacturer-specified period, typically 5 to 15 minutes, to allow these capacitors to discharge safely before proceeding.

Question 5

A recycler needs to ship a damaged lithium-ion battery removed from an EV to a specialized facility. According to U.S. Department of Transportation (DOT) regulations, how must this battery be transported?

Accepted Answer

By a carrier with a hazardous materials permit, using specially approved packaging designed for damaged lithium batteries.

Answer

The U.S. DOT's Pipeline and Hazardous Materials Safety Administration (PHMSA) classifies damaged, defective, or recalled (DDR) lithium-ion batteries as a high-risk hazardous material. They require very specific, approved packaging and must be transported by a carrier certified to handle such materials, following strict protocols found in 49 CFR 173.185(f).
