- 29 CFR 1910.147
- 29 CFR 1910.269
- 29 CFR 1910.303 (Correct answer)
- 29 CFR 1926.50
Correct answer: 29 CFR 1910.303
29 CFR 1910.303 covers general electrical safety requirements for wiring design and protection in general industry, applicable to EV service environments.
Question 2: What does the acronym 'FMVSS' stand for in the context of EV safety regulations?
- Federal Motor Vehicle Safety Standards (Correct answer)
- Federal Manufacturing and Vehicle Safety Specifications
- Fleet Management and Vehicle Safety Systems
- Federal Minimum Vehicle Safety Statute
Correct answer: Federal Motor Vehicle Safety Standards
FMVSS stands for Federal Motor Vehicle Safety Standards, the mandatory safety standards that all vehicles sold in the US must meet.
Question 3: Under SAE J1772, what is the maximum voltage permitted for Level 2 AC EV charging?
- 120V AC
- 208-240V AC (Correct answer)
- 480V AC
- 600V AC
Correct answer: 208-240V AC
SAE J1772 defines Level 2 charging as 208-240V AC, which is the standard for residential and commercial AC charging stations.
Question 4: Which regulation requires EV manufacturers to disclose battery chemistry, thermal management, and safety data to emergency responders?
- NFPA 70E
- NHTSA FMVSS 305 (Correct answer)
- SAE J2344
- EPA 40 CFR Part 86
Correct answer: NHTSA FMVSS 305
NHTSA FMVSS 305 establishes requirements for electric energy storage systems and mandates safety information disclosure for emergency responders.
Question 5: When servicing an EV high-voltage system, what minimum PPE insulation class should gloves be rated to handle voltages above 500V?
- Class 0 (1,000V rated)
- Class 1 (7,500V rated) (Correct answer)
- Class 2 (17,000V rated)
- Class 3 (26,500V rated)
Correct answer: Class 1 (7,500V rated)
Class 1 gloves rated to 7,500V are the minimum requirement for working on systems above 500V, providing adequate protection for most EV HV systems.
Question 6: According to IEC 61851, what does 'Mode 3' charging refer to?
- Slow AC charging using a standard household outlet
- Fast AC charging using a dedicated EV supply equipment connection (Correct answer)
- DC fast charging via CCS or CHAdeMO
- Wireless inductive charging
Correct answer: Fast AC charging using a dedicated EV supply equipment connection
IEC 61851 Mode 3 refers to AC charging using a dedicated EV supply equipment (EVSE) with a direct permanent connection to the AC network, including communication between the vehicle and EVSE.
Question 7: Which US agency is primarily responsible for regulating EV battery transportation safety in commercial shipping?
- EPA
- NHTSA
- PHMSA (Correct answer)
- OSHA
Correct answer: PHMSA
PHMSA (Pipeline and Hazardous Materials Safety Administration) regulates the transportation of hazardous materials including lithium batteries under 49 CFR.
