Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Elements Elements describe the essential outcomes. | Performance Criteria Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold and italicised text is used, further information is detailed in the range of conditions section. |
1. Prepare to depower and reinitialise BEV | 1.1 Job requirements are determined from workplace instructions 1.2 Workplace procedures and manufacturer specifications are accessed and interpreted 1.3 Hazards associated with the work are identified and risks are managed according to safety requirements and AS 5732 Electric vehicle operations - Maintenance and repair 1.4 Tools and equipment are selected and checked for serviceability 1.5 Vehicle is identified with warning tag or sign to indicate potential hazards |
2. Deactivate vehicle RESS | 2.1 SELV supply is located and disconnected according to manufacturer specifications 2.2 RESS service plug or manual service disconnect is located and removed to depower vehicle HV RESS according to manufacturer specifications 2.3 Vehicle is stabilised and checked for zero residual voltage according to manufacturer procedures 2.4 RESS service plug or manual service disconnect is secured and retained to prevent refitting by third party |

4. Complete work processes | 4.1 Final inspection is made to ensure work is to workplace expectations and vehicle is presented ready for use 4.2 Work area is cleaned, waste and non-recyclable materials are disposed of, and recyclable material is collected 4.3 Tools and equipment are checked and stored and any faulty electrical equipment is identified, tagged and isolated according to workplace procedures 4.4 Workplace documentation is processed according to workplace procedures |
This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.
Safety requirements must include: | work health and safety (WHS) and occupational health and safety (OHS) requirements, including procedures for: identifying hazards and controlling risks associated with: working with high voltages on BEV electrical systems wearing jewellery while working around high electrical currents determining appropriate procedures for minimising risk associated with hazards, including applying electrical safety precautions when: using personal protective equipment (PPE), including electrical safety gloves with 1000 volt rating and Australian standards rated HV insulating mat identifying and using firefighting equipment as appropriate using the ‘one hand’ rule following live system warning tags and signs depowering vehicle isolating HV RESS electrical supply stabilising vehicle electrical system. |
Tools and equipment must include: | those specified in the specific vehicle service maintenance procedures, 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. |
Before competency can be determined, individuals must demonstrate they can perform the following according to the standard defined in the unit’s elements, performance criteria, range of conditions and foundation skills:
safely depower the rechargeable energy storage system (RESS) and separated extra low voltage (SELV) system of two different battery electric vehicles (BEVs), and stabilise the vehicles ensuring that no residual high voltage (HV) is measured
safely reinitialise each BEV’s RESS and SELV system and confirm correct vehicle operation.
Individuals must be able to demonstrate knowledge of:
work health and safety (WHS) and occupational health and safety (OHS) requirements relating to depowering and reinitialising BEVs, including procedures for:
identifying hazards and controlling risks associated with:
working with high voltages on BEV electrical systems
wearing jewellery while working around high electrical currents
determining appropriate procedures for minimising risk associated with hazards, including applying electrical safety precautions when:
using personal protective equipment (PPE), including electrical safety gloves with 1000 volt rating and Australian standards rated HV insulating mat
identifying and using firefighting equipment as appropriate
using the ‘one hand’ rule
following live system warning tags and signs
depowering vehicle
isolating HV RESS electrical supply
stabilising vehicle electrical system.
requirements of AS 5732 Electric vehicle operations - Maintenance and repair
operating principles of RESS and SELV electrical systems relevant to a range of BEVs
application, purpose and operation of a range of vehicle RESS depowering and reinitialising methods.
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 BEVs 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 and safety equipment, including electrical safety gloves with 1000 volt rating and Australian standards rated HV insulating mat
manufacturer specifications and service procedures for the BEVs being depowered and reinitialised
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 depowering and reinitialising BEVs.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
