When ready to conduct the secondary inspection, complete the following...
1. Thermal Checks:
• Use thermal imaging tools to identify any residual heat in the battery.
• Monitor for signs of thermal runaway or overheating.
2. High-Voltage System Shutdown:
• Follow EV-specific shutdown procedures:
a) Utilize appropriate personal protective equipment (PPE) and tools.
b) Depower the vehicle's high-voltage system.
c) Test to confirm complete shutdown.
d) Place updated signs on the vehicle indicating it is safe for processing.
3. Document Findings:
• Record all observations, diagnostic results, and safety measures taken.
• Include details in the vehicle's inventory or work order for future reference.
4. Monitoring and Isolation:
• Continue to isolate high-risk vehicles for at least 24–48 hours or
longer if thermal runaway risks remain.
• Perform regular temperature checks and inspections during this period.
