Definition of Market:

The Automotive Hybrid Starter Generator (HSG) market comprises the production and sale of electric motors specifically designed to perform multiple functions within a hybrid vehicle powertrain. These functions primarily include starting the internal combustion engine (ICE), generating electricity to charge the vehicles battery (through regenerative braking), and acting as a motor to assist the ICE during acceleration or to power the vehicle at low speeds. Unlike traditional starters and alternators which operate separately, the HSG integrates these capabilities into a single unit, improving efficiency and reducing complexity.

Key components of an HSG system include the electric motor itself (often a permanent magnet synchronous motor or PMSM), a power inverter to control the motors operation, and associated sensors and control electronics. The motors design is crucial for its performance and efficiency, with factors like rotor and stator construction, magnet type, and winding configuration playing significant roles. The power electronics must handle high currents and voltages, enabling seamless transitions between starting, generating, and motoring modes. Control algorithms are equally important, optimizing the HSGs operation based on various parameters, such as battery state of charge, vehicle speed, and driver demand. Key terms related to the HSG market include: Belt-Integrated Starter Generator (BISG), which uses a belt drive; P2 HSG, which is integrated with the engines transmission; P3 HSG (integrated in transmission); Regenerative braking, the process of recovering energy during deceleration; and Mild Hybrid Vehicle (MHEV), where the HSG plays a pivotal role in improving fuel economy. Understanding these components and terminology is essential to navigating the complexities of this rapidly evolving market.
