Design of Open Battery Pack Interface for Electric Vehicle Personalization

Abstract

Satisfaction of personalized customers’ requirements of battery packs determines the competitiveness of electric vehicles. To meet the personalized requirements of battery packs, this paper develops a method for the design of an open interface for the connections and disconnections of battery pack modules to the electric vehicles. First, location and initial design scheme of the open interface are proposed based on relation analysis between customer demands and the electric vehicle module. To better facilitate the functional interactions between battery pack modules and electric vehicles, adaptability of open interface is then enhanced through design evaluation and modification. Influence of uncertainties due to unknown battery pack modules to the performance of electric vehicle is minimized through structure optimization of the open battery pack interface. The design can support electric vehicle personalization, better lifecycle flexibility, open technology innovation, and open business model.
