Electric(EV)/ Hybrid Vehicle Certification Program

Explore the introduction to the electric and hybrid vehicle certification program, outlining goals, scope, and core topics in EV and HEV technology.

Explore electric and hybrid vehicle concepts, from fundamentals to Toyota THS, including components, motor vs generator, regenerative braking, and battery management, through real-world operating scenarios.

Hybrid vehicles use two power sources—engine and motor—and regenerative braking to improve torque and fuel economy, without external charging.

Compare electric vehicles with petrol cars, highlighting electric motors' direct drive, efficiency, and regenerative braking. Rely on an IC engine using pistons and gears, yielding lower efficiency.

Compare electric, hybrid, and plug-in hybrid vehicles, explaining how electric motors, IC engines, regenerative braking, and external charging affect range, maintenance, fuel use, and emissions.

Explore the core components of hybrid and electric vehicles, including HV battery assembly, MG1 and MG2, inverter with boost and DC-DC converters, and the hybrid transaxle.

Compare the three hybrid system types: series, parallel, and series-parallel (THS) and see how engine, generator, motor, inverter, and high-voltage battery coordinate to drive wheels and charge the battery.

The lecture compares series, parallel, and Toyota hybrid system, then explains THS functions: idling time reduction, EV drive, motor assist, and regenerative braking to boost efficiency and fuel economy.

Explore how the high-voltage battery, inverter, generator, and MG1/MG2 power the engine and front wheels across ready on condition, start from rest, acceleration, deceleration, and reverse.

Explain how motor and generator operate in hv vehicles, with MG1 acting as motor or generator; motor drives wheels, generator charges the hv battery through regenerative braking.

Regenerative braking converts the vehicle’s kinetic energy into electrical energy to charge the HV battery, as the motor becomes a generator during braking.

Learn how the battery management system monitors the pack’s charge and temperature, enables charge balancing across cells, distributes coolant to prevent overheating, and prolong lithium-ion EV battery life.

Address common hybrid and electric vehicle FAQs. Explore ev mode, dead hv battery, battery location and cooling, life, jump-start risks, high-voltage safety, regenerative braking, and the battery management system.

Explore ac and dc motors in electric vehicles, noting dc motors use direct battery current, ac motors rely on an inverter, and the differences between brushless and conventional dc motors.

Discover skateboard chassis, 5000 lithium ion cells, and glycol-water coolant powering EVs and hybrids with a battery management system balancing cells across hybrid, plug-in hybrid, EV, and fuel cell types.

Learn how fuel cells generate electricity inside the car by hydrogen and oxygen reactions across a proton exchange membrane, with water as the only exhaust and no electricity storage.
