Bosch Chery 48V Vehicle Architecture China High Power Lightweight Platform

On April 24, Bosch (China) Investment Co., Ltd. and Chery Automobile Co., Ltd. formalized a framework agreement to jointly develop and mass-produce an advanced 48V vehicle architecture in China. This collaboration focuses on delivering a next-generation electrical architecture that balances power efficiency, system integration, and scalability. The solution is designed to address evolving demands for electrified vehicle platforms while maintaining reliability across multiple operating scenarios.

Enhanced Performance and Lightweight System Design

The newly developed 48V architecture delivers a significant increase in power supply capacity, reaching up to 15kW. This improvement supports higher electrical loads required by modern vehicle systems, particularly in electrified and intelligent vehicles. At the same time, system weight has been reduced by more than 10 kg, contributing to improved vehicle efficiency and overall performance. The lightweight approach also supports better energy utilization, aligning with industry trends toward optimized vehicle architectures.

Improved Responsiveness and System Integration

A key advancement within this architecture is the enhancement of the drive-by-wire chassis system. The steering motor response speed has been improved by more than 20%, enabling faster and more precise vehicle control. This upgrade enhances driving dynamics and supports advanced driver assistance functionalities. Additionally, the system’s high level of integration reduces complexity, making it more suitable for scalable deployment across different vehicle models and configurations.

Redundant Power Supply for Critical Safety Systems

The architecture incorporates an independent redundant power supply design, ensuring uninterrupted operation of critical vehicle systems. This includes intelligent driving modules, braking systems, and steering functions, which remain stable even under extreme conditions. Such redundancy is essential for safety-critical applications, especially as vehicles increasingly rely on electronic control systems for core functionalities.

Application in Premium Vehicle Segment

The jointly developed 48V architecture is planned for initial deployment in the flagship model of Chery’s premium brand, Exeed. This move highlights the strategic importance of advanced electrical architectures in enhancing vehicle performance, safety, and user experience. The collaboration between Bosch and Chery reflects a broader industry shift toward scalable, high-efficiency electrical systems tailored for next-generation mobility solutions.
