With the rapid development of electric vehicle technology in China, it has already captured a large portion of the global electric vehicle market. The current mainstream hybrid family sedans are the extended-range electric vehicle (REEV) and plug-in hybrid (PHEV). The extended-range electric vehicle (REEV), such as the Lixiang L series, uses a series-connected structure, with the engine acting solely as a generator, while propulsion relies entirely on the electric motor. This "electric vehicle + power bank" model allows for urban electricity costs as low as 0.07 yuan per 100 kilometers. PHEVs, such as the BYD DM-i, utilize a series-parallel architecture, with the engine capable of both generating electricity and directly driving the wheels. While this technology is more complex, they offer significant fuel efficiency advantages at high speeds. For example, the Zeekr 900 triple-motor version can achieve 0-100 km/h in 4.3 seconds while maintaining a fuel consumption of 6.2 L/100 km.
