  1. What is the correct procedure for neutralizing a small lithium-ion electrolyte spill at a recycling facility?

    Answer: Absorb with dry sand or approved absorbent; do NOT use water

    Lithium hexafluorophosphate electrolyte reacts with water to produce hydrofluoric acid, so dry absorbents are used instead of water.

  2. A recycler wants to resell a used EV battery pack for second-life energy storage. Which test is most critical before resale?

    Answer: State of health (SOH) capacity test

    SOH testing measures remaining usable capacity and determines whether the pack meets the minimum threshold for second-life applications.

  3. During EV dismantling, which tool should NEVER be used to cut through suspected high-voltage wiring?

    Answer: Standard wire cutters without insulation rating

    Standard wire cutters are not insulated to HV ratings and create a shock and arc flash hazard when cutting energized HV cables.

  4. What does a 'brick' condition mean in the context of a deeply discharged EV lithium-ion battery?

    Answer: The battery is permanently unusable due to over-discharge

    A bricked battery has been discharged below the minimum cell voltage threshold, causing irreversible chemical damage that prevents recharging.

  5. Which regulation governs the shipping of damaged or defective lithium batteries by ground transport in the U.S.?

    Answer: DOT 49 CFR Part 173.185

    DOT 49 CFR 173.185 sets packaging, marking, and documentation requirements for lithium battery shipments including damaged cells.

  6. An EV arrives at the yard with a battery management system (BMS) fault code indicating cell imbalance. What recycling implication does this have?

    Answer: Individual modules may have degraded cells requiring closer inspection before resale

    Cell imbalance indicates uneven degradation; modules must be individually capacity-tested before any second-life or resale application.

  7. What is the purpose of the high-voltage interlock loop (HVIL) in an EV battery system?

    Answer: To cut HV power automatically when a connector is opened or a cover is removed

    The HVIL is a low-current safety loop that triggers the contactors to open the HV circuit whenever a high-voltage connector is disconnected.
