Read the first 7 Safety Standards & Regulatory flashcards as text

  1. What is the significance of the 'orange color coding' standard for high-voltage cables in electric vehicles?

    Answer: It is required by SAE J1673 and ISO 6469 to identify HV cables for safety

    SAE J1673 and ISO 6469 standardize orange color coding for HV cables above 60V DC or 30V AC to warn technicians and emergency responders of electrocution risk.

  2. Which NFPA standard specifically addresses the fire safety of lithium-ion battery energy storage systems in commercial facilities?

    Answer: NFPA 855

    NFPA 855 is the Standard for the Installation of Stationary Energy Storage Systems, addressing fire safety for lithium-ion battery installations in commercial and industrial settings.

  3. When performing a pre-work risk assessment on an EV HV system, which hazard energy source is often overlooked but must be controlled per OSHA LOTO?

    Answer: Capacitors in the inverter retaining stored charge

    Inverter capacitors can retain dangerous voltage levels even after HV battery isolation, making capacitor discharge a critical step in LOTO procedures.

  4. The EPA's SmartWay program relates to EV technology in what regulatory context?

    Answer: It measures and certifies fuel efficiency and environmental performance of vehicles

    EPA's SmartWay program measures and certifies the environmental performance and fuel efficiency of vehicles, including EVs, helping consumers compare environmental impact.

  5. What does the 'control pilot signal' in SAE J1772 primarily communicate during the charging process?

    Answer: EVSE availability, current capacity, and vehicle readiness to charge

    The J1772 control pilot uses a PWM signal to communicate between EVSE and vehicle, indicating EVSE availability, available current capacity, and vehicle readiness states.

  6. Under which condition does ISO 6469-3 require the automatic disconnection of an EV's high-voltage system?

    Answer: When a crash or rollover is detected via the vehicle's safety systems

    ISO 6469-3 requires automatic HV disconnection when a crash or severe impact is detected, reducing electrocution and fire risk for occupants and rescuers.

  7. A shop receives a flood-damaged EV with a submerged battery pack. According to safety best practices and regulatory guidance, what is the first priority?

    Answer: Quarantine the vehicle outdoors away from structures due to thermal runaway risk

    Flood-damaged lithium-ion batteries are at high risk of delayed thermal runaway; the vehicle must be quarantined outdoors, away from buildings, pending manufacturer guidance.
