Length 60.0 hours

Course outline View

This course explores high-voltage battery systems used in modern electric vehicles and renewable energy storage. Students are provided with hands-on experience in handling, diagnosing, and repairing high-voltage battery packs. Key areas of study include battery architecture, the disassembly and reassembly of battery packs, safe procedures for discharging and recharging, and the techniques required for battery balancing. Learners will diagnose common issues and perform repairs on high-voltage batteries, gaining insight into both theoretical concepts and practical applications. A critical component of the course is the development of skills necessary for rebuilding battery packs, ensuring they meet performance and safety standards. Testing procedures and module-level diagnostics are also introduced. This course emphasizes safety and best practices, preparing students to work confidently with high-voltage systems in real-world scenarios.

Prerequisites

ELRT 1003, ELRT 1004.
