Modification History



Release 2 

Replaces AURETH3001 Depower battery electric vehicles (Release 1)

Reference to OHS legislation replaced with new WHS legislation

Unit Descriptor

Unit descriptor 

This unit describes the performance outcomes required to depower battery electric vehicles (BEVs). It involves ensuring the vehicle high voltage (HV) supply system is isolated prior to commencing service and repair work.

Importance is placed on the application of HV and low voltage (LV) electrical safety procedures.

Licensing, legislative, regulatory or certification requirements may apply to this unit in some jurisdictions. Users are advised to check with the relevant regulatory authority.

Application of the Unit

Application of the unit 

Work applies to the service and repair of HV BEVs in the automotive industry.

Licensing/Regulatory Information

Refer to Unit Descriptor.

Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria


Performance Criteria 

1. Prepare for work

1.1. Procedures and information  are sourced and work requirements are confirmed

1.2. Service method appropriate for the specific circumstances is selected and prepared for

2. Deactivate power control

2.1. Workplace health and safety (WHS) requirements  and other relevant information for deactivation are identified

2.2. Procedure to deactivate vehicle at main control is followed to commence depowering process

3. Isolate vehicle power supply

3.1. HV power supply connection is located and isolated according to manufacturer instructions, taking appropriate precautions  to prevent electric shock to self and others

3.2. LV power supply is located and disconnected according to manufacturer instructions and vehicle and workplace safety procedures

3.3. Vehicle is stabilised and checked for residual voltage in system

3.4. HV power supply connection is secured and retained to prevent re-fit by third party

3.5. HV power supply is identified with warning tag or sign to indicate potential hazards

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • technical skills to use workplace technology and tools to:
  • deactivate BEVs
  • locate and disconnect LV power supply in BEVs
  • locate, isolate and stabilise HV power supply in BEVs
  • communication skills to:
  • communicate effectively regarding work requirements with supervisor, other workers and customers
  • confirm work requirements and specifications
  • literacy skills to interpret technical information and specifications
  • self-management skills to:
  • manage risks and hazards associated with HV, BEV electrical systems
  • manage workflow and productivity

Required knowledge 

  • WHS requirements, including:
  • safe work practices
  • electrical safety relevant to BEVs
  • general principles of operation of HV and LV electrical systems relevant to BEVs
  • applicable commonwealth, state or territory legislation, regulations, standards and codes of practice relevant to working on BEVs
  • workplace policies procedures including quality, reporting and recording procedures relevant to working on BEVs

Evidence Guide

Evidence Guide 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

The evidence required to demonstrate competency in this unit must be relevant to workplace operations and satisfy all of the requirements of the performance criteria and required skills and knowledge.

A person who demonstrates competency in this unit must be able to:

  • comply with WHS requirements and safe work practices
  • safely deactivate the vehicle and isolate HV and LV power supply
  • ensure the vehicle is depowered, stabilised and no residual HV power exists.

Context of, and specific resources for assessment 

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

Assessment is to occur:

  • using standard workplace practices and procedures
  • following safety requirements
  • applying environmental constraints

Assessment is to comply with relevant:

  • regulatory requirements
  • Australian standards
  • industry codes of practice

Competency is to be assessed using a BEV that uses HV and LV alternating and direct current (AC/DC) electrical systems. Where simulation is used, an operational BEV must be included in the simulation.

The following resources must be made available for the assessment of this unit:

  • appropriate PPE
  • a BEV
  • manufacturer specifications for the BEV
  • testing equipment
  • full range of essential tools and equipment
  • workplace documentation.

Method of assessment 

Assessment must satisfy the endorsed Assessment Guidelines of this Training Package.

Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with the application of required skills and knowledge.

Assessment methods must be by direct observation of tasks and include questioning on required skills and knowledge to ensure correct interpretation and application.

Competence in this unit may be assessed in conjunction with other units which together form part of a holistic work role.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate the needs of diverse clients.

Assessment processes and techniques must be culturally sensitive and appropriate to the language, literacy and numeracy capacity of the candidate and the work being performed.
