Developing new energy vehicles (NEVs) is essential for China’s automotive industry to achieve carbon peak and carbon neutrality goals. The development of a NEV platform is an effective means for automotive companies to balance the development cost, development time, and product performance of NEVs. However, there is no clear solution to choosing new energy vehicle platform development strategies and models for automotive companies. This paper mainly studies the significance of NEV platform development, the classification and characteristics of NEV platforms, and the development strategies and trends of NEV platforms for automotive companies. The study results found that choosing a new dedicated electric platform (NDEP) is inevitable for the latest automotive companies, such as TESLA Motors. An adapted electric platform (AEP) is a temporary solution that meets the dual credits policy. It lacks competitiveness and has been gradually eliminated for the traditional automotive companies. The new dedicated electric platform is a long-term development solution when comprehensively considering the market, technology, and policy. The compatible platform (CP) is a transitional solution when considering the development trend of automotive powertrain, the market size of NEVs, and the platform technology of NEVs. Besides, joint development and shared use is the primary development model for the automotive enterprise in the future. Finally, companies should increase their research and development efforts on NEV architecture platforms to maximize platform-based development’s scale effect and application value. The research can provide strategic guidance for automotive companies to develop NEV platforms.
