Fundamentals of High Voltage xEV, Safety, and PPE C2001



Do you know what personal protective equipment (PPE), tools, and instruments are needed to keep you safe around high voltage (HV) vehicles? Are you aware of how to protect yourself or your employees when working around high voltage systems and platforms?

Safety is paramount when working around any type of high voltage. As electric vehicles (EV) and EV fleets become more prevalent, the critical need for OEMs, suppliers, companies, and organizations to provide comprehensive safety training for teams working with or around xEV systems and platforms increases. Engineers, technologists, and technicians involved in the design, development, testing, and/or servicing of high voltage EV systems must learn to protect themselves using safe procedures and practices.

This one-day course explains EV safety fundamentals, including personal protective equipment (PPE) and how to develop and establish common safety procedures for working around high voltage vehicles. You’ll learn how to safely connect and disable a high voltage system for testing and diagnostic purposes - and during disaster and crash events. You’ll be introduced to various types of EV, their characteristics, architecture, and components, including how to determine critical connection and disconnection procedures. The course explains the tools, PPE, safety procedures, and practices that should be in place, as well as methods to establish new procedures and test PPE. It also discusses how to develop and comply with FMVSS 305 requirements and OSHA PPE guidelines.

Learning Objectives

By participating in this course, you'll be able to:

  • Describe the various xEV’s subsystems and components
  • Identify, select, test, care for high voltage (HV) electrical gloves per ASTM requirements
  • Recite the steps to disable a HV EV
  • Utilize appropriate processes and PPE tools when disabling/connecting EV
  • Safely measure HV vehicle platforms
  • Explain the EV grounding mechanism
  • Explain OSHA PPE & FMVSS 305 requirements
  • Describe interlock system types, operational mechanism, strategic location, testing, schematic circuits, failure modes, diagnostics, and standardization
  • Determine how to deal with HV vehicle subsystems during vehicle crash
  • Examine the EV HV system for faults, failures, and discharge circuits

Who Should Attend

This course would benefit OEM, Tier I, II and III suppliers, and aftermarket companies’ vehicle electrification engineers, engineering technologists, and related professionals involved in the design, development, testing, support, and service of high voltage EV components and systems. Technicians involved in testing, diagnosing, disabling, and servicing high voltage EV may also benefit from this course.

Prerequisites

An engineering degree or prior knowledge of high voltage EV systems is not required in order to benefit from and successfully complete this course. However, prior experience in the automotive field as an engineer, technologist, or technician would be beneficial.
