Mild Hybrid

There are two types of mild hybrid – parallel and series. A parallel mild hybrid uses the same ‘Stop-Start’ system as a micro hybrid plus it uses the electric motor to supplement the engine during acceleration. It cannot usually power the car by the electric motor alone. It is powered by a battery which is charged either by capturing energy usually lost through braking or by the engine slightly over-performing at cruising speed. A series mild hybrid propels the car by an electric motor which is charged by a petrol engine or during deceleration.
