Sangari's automotive equipment brings a complete, functional vehicle drivetrain into the classroom, built from the components the manufacturer fits to production cars. The AM771 apparatus carries a petrol-electric hybrid drivetrain on a mobile frame: petrol engine, two motor-generators, power-split automatic transmission, high-voltage traction battery and power electronics, the cooling and climate circuits and the exhaust line with catalytic converter. All components are original parts of the Toyota Hybrid System II and are wired as in the vehicle. The drivetrain runs in electric, engine, combined and regeneration mode, and the energy flow between battery, motor-generators and engine changes with the load. All sensor and actuator circuits are brought out to a test panel with 4mm quick-connect measuring points; each measuring point is at the same time a break point, so that 62 faults are set without tools for fault-finding exercises. The drivetrain remains visible behind removable protective panels.
