Session 2: Creating an Electrically Safe Work Condition
Thursday, May 1, 2025, 4PM PST
This live session covers the process of creating an Electrically Safe Work Condition to prevent electrical injuries in high voltage environments. Topics include the procedures for disconnecting low and high voltage circuits, conducting Zero Voltage Verification (ZVV), and following safe work practices in compliance with OSHA regulations. Key steps include lockout/tagout (LOTO) procedures, proper disconnection of high voltage battery systems, and methods for verifying the absence of voltage. The webinar will also address the importance of temperature monitoring, use of appropriate tools and PPE, and maintaining safety during electrical work.

Session 3: EV Maintenance Flow: Vehicle Initialization
This live session guides participants through the essential safety and diagnostic procedures required to return an electric vehicle to service after high-voltage repairs. Learners will explore the EV Initialization Maintenance Flow with a focus on demonstrations using a milliohm meter and a megohmmeter to perform safety checks, including bonding tests, Hioki measurements, and insulation resistance tests. Through hands-on comparisons between multimeters and milliohm meters, participants will evaluate conductor resistance and its impact on heat generation, diagnose joint integrity in high-voltage contactor boxes, and interpret stator winding resistance data to assess motor health. The session also covers grounding and electrical isolation checks aligned with FMVSS 305 and ECE-R-100 standards, ensuring vehicles are safely initialized and ready for operation.

Session 4: Level 2 High Voltage Safety Skills Assessment
This final session provides an opportunity for participants to demonstrate their proficiency in creating an electrically safe work condition when shutting down a high voltage system. Attendees will demonstrate their ability to disconnect low and high-voltage circuits, perform zero voltage verification (ZVV), and apply safe work practices in compliance with OSHA regulations. Key skills to be demonstrated include appropriate PPE and tool selection, proper disconnection of high voltage battery systems, and methods for verifying the absence of voltage. Proficiency in these skills is required to earn certification.
