The intelligent revolution experienced by China's automotive power system industry in the past 10 years lies in the transition from 'mechanical drive' to 'AI driven intelligent energy units'. BYD has launched the world's first twelve in one intelligent electric drive system, which integrates motor, electronic control, DC-DC, OBC, PDU, VCU and BMS. It supports ultra-high speed of 23000rpm and 1200V silicon carbide platform, with a system efficiency of 97.5%, achieving the energy efficiency benchmark of '12 kilometers per kilowatt hour'; The Huawei DriveONE six in one/ten in one platform is empowered by ICT technology and equipped with AI intelligent torque control and thermal runaway warning. It has obtained ISO 26262 ASIL D functional safety certification and has been used in over 2 million vehicles. The battery management is achieved by Ningde Times' 'Tianxing II' BMS, which realizes intelligent temperature control and overcurrent self-protection in all scenarios, combined with cloud data closed-loop, extending the lifespan by more than 15%; The thermal management system is built by NIO as a 'vehicle station cloud' collaborative closed-loop system, with intelligent preheating and constant temperature of the battery swapping station to ensure low-temperature endurance without discount, reducing energy consumption by 20%. L3 level autonomous driving has forced the three electric systems to achieve full link redundancy and millisecond level collaboration. The Dongfeng DF30 automotive MCU chip has been mass-produced, with a localization rate exceeding 67%. The industry is transforming from a 'component supplier' to an 'intelligent power system architecture provider', with a penetration rate of over 80% for intelligent power systems by 2025.
