HIGH VOLTAGE VEHICLE SAFETY SYSTEMS AND PPE
High voltage vehicle safety is a primary concern for every technician or engineer involved in developing, diagnosing or repairing hybrid or electric vehicles. Engineers/technicians working in this field should complete safety training before they interface with hybrid, plug-in or electric vehicles. This course provides you with fundamental technical and safety information on high voltage personal protective equipment (PPE) such as how to test high voltage gloves, when and where to send high voltage gloves for periodic testing, and how to safely use test equipment for measuring high voltage components in live and disabled high voltage systems. circuits, and DC and AC isolation detection systems that are monitored by high voltage controllers to maintain the required resistance barrier between the vehicle technician/engineer and the vehicle body/chassis to mitigate the possibility of an electrical shock event. LEARNING OBJECTIVES By attending this seminar, you will be able to: • Properly care for high voltage electrical gloves • Field test high voltage electrical gloves • Identify providers that test high voltage gloves required by ASTM requirements • Disable a vehicle high voltage system • Safely acquire measurements on a high voltage system • Describe the operation of automotive AC and DC isolation fault detection systems • Apply FMVSS 305 requirements and SAE J1766 Recommended Practice to testing high voltage vehicle safety systems • Describe the operation of high voltage interlock circuits and passive and active bus discharge circuits • Test the high voltage system for isolation faults, interlock circuit failures and passive and/or active discharge circuits • Describe how and when to use high voltage gloves, serial data (Scan Tool), insulation meter, and DVOM to test the high voltage system and components The vehicle safety systems contain interlock circuits, passive and active bus (capacitor) discharge
Much of the high voltage vehicle safety systems information covered in this course is based on the FMVSS requirements and SAE Recommended Practices.
