Learning Outcomes and Application | This unit describes the performance outcomes required to diagnose and repair faults in high voltage (HV) direct current (DC) to low voltage (LV) DC converters in battery electric vehicles (BEVs). It involves preparing for the task, selecting the correct diagnostic procedure, carrying out the diagnosis and the repair, performing post-repair testing, and completing workplace processes and documentation. Importance is placed in the unit on applying electrical safety procedures when working on HV rechargeable energy storage systems (RESS).It applies to those working in the automotive service and repair industry. HV DC to LV DC converters include circuits in BEVs.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication. | ||
Duration and Setting | X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting. 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 BEV DC to DC converters that they have worked on, 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 HV insulating mat with Australian standards rating manufacturer specifications for BEV DC to DC converters AS 5732 Electric vehicle operations: Maintenance and repair two different BEVs with DC to DC converters accessible for diagnostic and repair or replacement activities electrical diagnostic equipment appropriate to the BEV being diagnosed and repaired, including: digital multimeter with Cat III 1000 volt rating insulation tester scan tool oscilloscope residual voltage tester, if specified in original equipment manufacturer (OEM) test requirements tools, equipment and materials appropriate for repairing DC to DC converters in BEVs. |
