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 RESS in BEVs that they have repaired, 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, including electrical safety gloves with 1000 volt rating and Australian standards rated HV insulating mat

manufacturer specifications for BEV and RESS

AS 5732 Electric vehicle operations - Maintenance and repair

two different BEVs with RESS and associated components accessible for diagnosis and repair or replacement activities

electrical diagnostic equipment appropriate to the BEV being diagnosed and repaired, including:

digital multimeter with Cat III 1000 volt rating

insulation tester

residual voltage tester, if specified in original equipment manufacturer (OEM) specifications

scan tool

oscilloscope

tools, equipment and materials appropriate for repairing BEV RESS and their components.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
