Study and Practice on the Architecture Design of Electrified Vehicle Platforms

The fundamental significance of the Architecture of a vehicle platform was studied and practiced in this paper. Using Architecture to determine different kinds of modular platforms was an effective means, and also put forward new proposals for their optimization. Based on benchmarking and development experiences of passenger vehicle modular platforms, the concept and characteristics of a vehicle platform architecture was proposed in this paper. By analyzing the evolution process and development strategy of modular platforms for fuel engines, hybrid powertrains and battery electric vehicle platforms, the internal motivations for the construction of the platform was refined. The elements and methods of platform architecture design were summarized, such as primary parameters, modules, interfaces, principles etc. It has reference significance for the architecture development of brand-new platforms and vehicle models in the future.
