Description
Employability Skills
Learning Outcomes and Application This unit describes the performance outcomes required to depower and reinitialise hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs). It involves ensuring that the vehicle high voltage (HV) rechargeable energy storage system (RESS) is isolated before commencing any service or repair work. It also involves calibrating vehicle systems that may need resetting once the energy storage system is reinitialised. Importance is placed in the unit on applying 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.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessors must satisfy NVR/AQTF assessor requirements.

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 HEVs or PHEVs that they have depowered and reinitialised, 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 and service procedures for the HEVs or PHEVs being depowered and reinitialised

AS 5732 Electric vehicle operations - Maintenance and repair

two different operational HEVs or PHEVs 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) specifications

scan tool

tools, equipment and materials appropriate for depowering and reinitialising RESS in HEVs and PHEVs.
