An automotive hybrid starter generator (HSG) is a component used in hybrid and mild hybrid vehicles to improve engine start/stop functionality and enhance overall vehicle efficiency. It plays a crucial role in modern hybrid vehicles by combining starter and generator functions, supporting start-stop systems, enabling regenerative braking, and boosting vehicle efficiency and performance.

The main types of automotive hybrid starter generators include 12-volt, 48-volt, and other configurations. A 12-volt hybrid starter generator is a compact system that integrates the roles of both starter and generator to enhance fuel efficiency and reduce emissions in hybrid vehicles. It comprises components such as an electric motor or generator, a power electronic controller, and a battery, and it can offer varying power levels, low (up to 15 kW), medium (15-30 kW), and high (above 30 kW). These systems are used in passenger cars, light commercial vehicles, and heavy commercial vehicles.
