Release 2 

Replaces AURETH4010 Test high voltage batteries in hybrid 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 test high voltage (HV) batteries in hybrid electric vehicles (HEVs). It includes identifying and confirming safety requirements, preparing for work, testing HV batteries, and completing work processes, including clean-up and documentation. Work requires individuals to demonstrate some judgement and problem-solving skills in managing own work activities.

Importance is placed on the application of HV 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 testing HV batteries in HEVs, such as cars, trucks, motorcycles, marine applications and wheeled plant or equipment.

Licensing/Regulatory Information

Refer to Unit Descriptor.

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:

  • observe safety procedures and requirements
  • communicate effectively with others involved in or affected by the work
  • select methods and techniques appropriate to the circumstances
  • complete preparatory activity in a systematic manner
  • test HV batteries in HEVs according to requirements
  • complete relevant documentation for recording HEV battery test results.

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 an HEV that uses HV and LV AC/DC electrical systems. Where simulation is used, an operational HEV must be included in the simulation.

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

  • appropriate PPE
  • an HEV
  • manufacturer specifications for the HEV
  • 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.
