Hybrid vehicles

Definition

Hybrid vehicles utilize both an internal combustion engine and an electric motor for propulsion. They improve fuel efficiency and reduce emissions compared to traditional gasoline-powered cars.

5 Must Know Facts For Your Next Test

1. Hybrid vehicles rely on electromagnetic induction to charge their batteries through regenerative braking.
2. The electric motor in a hybrid vehicle can act as a generator, converting kinetic energy into electrical energy during braking.
3. Inductive charging systems can be used to wirelessly charge the batteries of hybrid vehicles.
4. Inverters in hybrid vehicles convert DC from the battery to AC for the electric motor, utilizing electromagnetic principles.
5. Hybrid vehicles often use permanent magnet motors, which are crucial components studied in electromagnetism.
