AURETH001 Depower and reinitialise battery electric vehicles

Modification History

Release	Comment
Release 1	New unit of competency.

Application

This unit describes the performance outcomes required to depower and reinitialise battery electric vehicles (BEVs). It involves ensuring 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.

Elements and Performance Criteria

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
3. Reinitialise vehicle RESS	3.1 SELV and RESS service plug or manual service disconnect are reconnected in the correct order and vehicle is reactivated 3.2 Diagnostic test equipment is used to check and recalibrate subsystems affected by depower process as required 3.3 RESS and vehicle subsystems are checked for correct operation 3.4 Post-reactivation faults are reported according to workplace procedures
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

Foundation Skills

This section describes those language, literacy, numeracy and employment skills that are essential to performance and are not explicit in the performance criteria.

Skills	Description
Learning skills to:	locate appropriate sources of information efficiently.
Reading skills to:	interpret text, symbols and diagrams in depowering and reinitialising information in manufacturer specifications, and workplace instructions and procedures.
Writing skills to:	legibly and accurately fill out workplace documentation when reporting diagnostic findings, making repair recommendations, and recording parts and material used.
Oral communication skills to:	listen to workplace instructions and ask questions to clarify job requirements participate in verbal exchanges when depowering and reinitialising BEVs.
Numeracy skills to:	match electrical components and part identification numbers to workplace instructions, vehicle and component part lists, and manufacturer specifications interpret vehicle electrical measurements and readings on digital and analogue gauges interpret measurements of residual voltage and high voltages relating to BEVs.
Planning and organising skills to:	plan own work requirements and prioritise actions to achieve required outcomes and ensure tasks are completed within workplace timeframes.
Problem solving skills to:	identify faults in reinitialising process that need to be reported.
Technology skills to:	use specialised tools.

Range of Conditions

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.
