Learning Outcomes and Application | This unit describes the performance outcomes required to diagnose and repair faults in the traction motor speed control systems in battery electric vehicles (BEVs). These systems may be referred to as digital motor controllers (DMCs) or motor control units (MCUs). The unit 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 high voltage (HV) rechargeable energy storage systems (RESS).It applies to those working in the automotive service and repair industry. Motor speed control systems 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 traction motor speed control systems 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 traction motor speed control systems AS 5732 Electric vehicle operations: Maintenance and repair two different BEVs with traction motor speed control systems accessible for diagnosis 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 high voltage traction motors in BEVs. |
