Release 1

This version first released with the Automotive Retail, Service and Repair Training Package Version 7.0.

Supersedes and is equivalent to AURETH002 Service and maintain battery electric vehicles.

Application

This unit describes the skills and knowledge required to inspect 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 both high voltage (HV) rechargeable energy storage systems RESS and separated extra low voltage (SELV) electrical safety procedures.

It applies to individuals working in the automotive service and repair industry.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Pre-requisite Unit

AURETH101 Depower and reinitialise battery electric vehicles

Competency Field

Electrical

Unit Sector

Technical – Hybrid Vehicle and Battery Electric Vehicle

Release 1

This version first released with the Automotive Retail, Service and Repair Training Package Version 7.0.

Supersedes and is equivalent to AURETH002 Service and maintain battery electric vehicles.

Performance Evidence

The candidate must demonstrate the ability to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including evidence of the ability to:

  • inspect and maintain at least two different battery electric vehicles (BEVs).

Knowledge Evidence

The candidate must be able to demonstrate knowledge to complete the tasks outlined in the elements, performance criteria and foundation skills of this unit, including knowledge of:

  • methods to locate and interpret information required to inspect and maintain battery electric vehicles, including:
  • Australian Standards (AS) 5732 Electric vehicle operations - Maintenance and repair

Assessment Conditions

Competency is to be assessed in the workplace or a simulated environment that accurately reflects performance in a real workplace setting.

Assessment must include direct observation of tasks.

Where assessment of competency includes third-party evidence, individuals must provide evidence that links them to the BEVs that they have inspected and maintained e.g. repair orders.

Assessors must verify performance evidence through questioning on skills and knowledge to ensure correct interpretation and application.

The following resources must be made available:

  • automotive repair workplace or simulated workplace
  • PPE and safety equipment, including electrical safety gloves with 1000 volt rating and Australian standards rated HV insulating mat
  • manufacturer specifications and inspection procedures for the BEVs being inspected and maintained
  • AS 5732 Electric vehicle operations - Maintenance and repair
  • two different BEVs as specified in the performance evidence
  • electrical test equipment, including:
  • digital multimeter with Cat III 1000 volt rating
  • insulation tester
  • residual voltage tester, if specified in original equipment manufacturer (OEM) test requirements
  • scan tool
  • tools, equipment and materials appropriate for servicing and maintaining BEVs.
