The automotive powertrain system is the entire mechanical process of transmitting power generated by the engine through a series of power transmissions to the wheels. Modern automotive powertrain systems are mainly divided into fuel-powered, pure electric, hybrid, and hydrogen fuel cell powertrains. Their development has evolved from steam engines and internal combustion engines to electrification.
Future automotive powertrain technology is evolving towards diversification, efficiency, cleanliness, and intelligence, forming a diversified pattern of "pure electric dominance and hybrid transition." Supercharging technology, silicon carbide (SiC) power devices, 800V/900V high-voltage architecture, and the deep integration of powertrain systems with intelligent technology are becoming important trends.
