Description
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.
Notes
Elements and Performance Criteria
1. Prepare to depower and reinitialise HEV and PHEV
- 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 tags 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 and testing 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
