Description
This unit describes the performance outcomes required to service and maintain battery electric vehicles (BEVs). It involves working with automotive electrical components, maintaining rechargeable energy storage systems (RESS), and performing basic tests on electric drive motors. Importance is placed in the unit on applying high voltage (HV) RESS and separated extra low voltage (SELV) electrical safety procedures.It applies to those working in the automotive service and repair industry.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare to service and maintain BEV

  • 1.3 Hazards associated with the work are identified and risks are managed according to safety requirements and AS 5732 Electric vehicle operations - Maintenance and repair
  • 1.4 Tools and equipment are selected and checked for serviceability
2. Test RESS and drive motor system operation
  • 2.1 Diagnostic equipment is used to retrieve system parameters and information
  • 2.2 RESS and vehicle drive motor system are tested for correct operation according to manufacturer specifications
  • 2.3 Problems associated with performance of RESS or drive motor system are identified and reported according to workplace procedures
3. Deactivate vehicle RESS
  • 3.1 Vehicle is depowered according to manufacturer specifications and workplace procedures
  • 3.2 Vehicle is identified with warning tag or sign to indicate potential hazards
  • 3.3 SELV supply is located and disconnected according to manufacturer specifications
  • 3.4 RESS service plug or manual service disconnect is located and removed to depower vehicle HV RESS according to manufacturer specifications
  • 3.5 Vehicle is stabilised and checked for zero residual voltage according to manufacturer procedures
  • 3.6 RESS service plug or manual service disconnect is secured and retained to prevent refitting by third party
4. Check drive motor and associated components

  • 5.2 Problems associated with performance of electrical subsystems and components are identified
  • 5.3 Required corrective action is reported according to workplace procedures
6. Reinitialise vehicle RESS
  • 6.1 SELV and RESS service plug or manual service disconnect are reconnected in correct order, and vehicle is reactivated
  • 6.2 Diagnostic test equipment is used to check and recalibrate subsystems affected by depower process as required
  • 6.3 RESS and vehicle subsystems are checked for correct operation
  • 6.4 Post-service testing is carried out to ensure correct and safe operation of BEV, any reported problems are resolved, and no other problems are present
7. Complete work processes
  • 7.1 Final inspection is made to ensure work is to workplace expectations and vehicle is presented ready for use
  • 7.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected
