EV Transit Bus Safety Awareness and Familiarization SC-BEV-5000-I

EV Transit Bus Safety Awareness and Familiarization

Prerequisites: DVOM Course (preferred) or thorough understanding of meters or equivalent experience.

Course Description: This course will provide a general understanding of safety do’s and don'ts when working around all-electric high voltage (HV) transit vehicles. This course is not intended as a replacement for manufacture specific training and does not qualify the student to diagnose, repair, and work on HV vehicles.

Course Benefits: Students will become familiar with all-electric high voltage (HV) transit vehicles to include high voltage electrical systems and their safe operation. Students will learn essential aspects of the high-voltage drive system including safety protection and safe operation.

Who Should Attend: Transit agency technicians/mechanics who need to familiarize themselves with all-electric high voltage (HV) transit vehicles.

What you will learn:

  • Identify the vehicles high-voltage components
  • Explain the required Personal Protective Equipment (PPE)
  • Describe the preparations prior to working on or near any high-voltage systems
  • Explain the vehicle safety systems
  • Identify HV Components and cables in an EV transit bus
  • Understand the definitions, terminology, and units of measure, of electrical energy storage and consumption
