ELECTRICAL/ELECTRONICS AND ELECTRONIC SYSTEMS
• Follow guidelines in how to properly maintain High Voltage Electrical Safety gloves • Field test High Voltage Safety gloves before each use • Properly interface a Differential Oscilloscope probe when measuring voltage in High Voltage systems • Apply correct Category (CAT) ratings when using or purchasing tools or equipment • Use an Insulation Resistance tester to test and identify components for any insulation failures Who Should Attend High Voltage Safety is a primary concern when any engineer is developing, verifying, or validating a vehicle electrification system. This course will provide essential information, and the associated electrical requirements of high voltage in electrical systems and tools associated with measuring high voltage system voltage and current. The associated Personal Protection Equipment (PPE) necessary for any engineer interfacing with high voltage systems is also an integral segment of this course. Topical Outline Part 1: Electrical Circuits and Personal Protection Equipment (PPE) • General Electrical Safety Precautions −− Ground Paths and the Technician • High Voltage Circuits and Scope Safety • Additional High Voltage Testing Considerations −− Partial Discharge and Electric Machine Winding Failure
At the conclusion of this series, you will be equipped to describe the operation of vehicle high voltage safety systems, how to test them, why they can cause a no-start condition, and how to test the system with special tools and scan tools to identify isolation fault areas for practical application. Ford, GM, Honda, Lexus, Toyota and other popular products are featured. While the duration of the course is four hours, the estimated time to completion, including knowledge checks and the final learning assessment, is four and one half hours. Learning Objectives By participating in this On Demand Course, you will be able to: • Identify High Voltage systems by color code • Recognize the construction and operation of Manual Disconnect systems • Know the location of the Manual Disconnect • Describe the operation of High Voltage Manual Disconnect systems • Identify Interlock Safety systems used on High Voltage systems by using circuit diagrams • Describe the operation of High Voltage Interlock systems Who Should Attend The design and implementation of high voltage vehicle safety systems is a requirement for Engineers that develop vehicle electrification products. Engineers with limited or some knowledge of high voltage vehicle electrification systems, or those that need to update their current knowledge or just need a good refresher, will benefit.

High Voltage Vehicle Safety Systems 4 Hours | On Demand Course I.D.# PD291808 This four-part course from SAE training partner FutureTech* is most beneficial if completed before servicing hybrid, plug-in and electric vehicles. These vehicles contain high voltage DC and AC safety systems that are monitored by vehicle systems controllers that will maintain a safety barrier between the vehicle operator and the vehicle body/chassis to mitigate the possibility of electrical shock. This presentation will provide the technical information and background to know how these systems operate and affect vehicle operation and driveability.
