Technician Handbook 601 Hybrid Systems for Collision Repair Hybrid System Components Hybrid vehicles share many similar basic components. (See Repair Manual for model-specific components.) Common hybrid system components include: Engine • Drives the vehicle at medium to high speeds • Can drive MG1 to generate electricity when required Hybrid Transaxle Houses two Motor/Generators and a compound gear unit.
• MG1 serves as the starter motor for the engine, and as a generator to convert energy from the engine into electricity • MG2 drives the vehicle at low speeds, and serves as a generator to convert energy from braking into electricity • The compound gear unit balances the output from the two Motor/Generators Inverter Assembly • Boosts high-voltage DC to an even higher-voltage AC to power MG1 & MG2 • Changes AC back to DC during power generation • Coverts high-voltage DC to 12 V DC 6 Collision Repair & Refinish Training
