May 12th, 2026 8am-4pm CST Off-Highway Machine Electrification 101
Course Overview
This course provides a foundational understanding of high-voltage (HV) electrical architectures and components for electrified off-highway machines such as construction, agricultural, and mining equipment. Participants will explore system-level design principles, component interactions, safety and reliability considerations, routed harness manufacturing, and emerging standards. The curriculum emphasizes practical integration challenges—thermal management, energy optimization, and mechanical-electrical interface design—under demanding duty cycles and harsh environments.
Students will learn to interpret power performance charts, apply standards (IEC, ISO, SAE), and implement quality assurance and diagnostic practices for HV systems. Hands-on exercises reinforce theoretical concepts through real-world scenarios, preparing engineers to design and validate electrified off-highway platforms.
