Elements

Learning Outcomes

This unit describes the skills and knowledge required to diagnose and repair faults in the high voltage (HV) direct current (DC) to low voltage (LV) DC of battery electric vehicles (BEVs). The unit involves preparing for the task, sourcing a diagnostic testing strategy, diagnosing the cause of the fault, carrying out 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). The unit applies to those who work 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.
