Semi-hybrids, which are not charged using a power cable, use the electric motor to assist the combustion engine.
In hybrids, the electric motor and battery are larger than in semi-hybrids. Hybrids can power the vehicle using the electric motor for short distances and recharge its battery using the motor or through regenerative braking.
A plug-in hybrid can be recharged by literally plugging it into a charging point at home, or in a public one. It offers greater pure electric autonomy thanks to the larger battery and electric motor. The plug-in hybrid allows many people to make their normal commute to and from work using the emission-free, electric powered engine.
