The purpose of this paper is to clarify the real state of affairs that companies without automakers, like auto-body manufacturer and auto-parts supplier, which have been entering EV market. In addition, we analyze whether the automobile proceeds toward product-modularization. The important fact we found through the case study of three companies, Toyota Auto Body, NTN and SIM-Drive is that EV, at least developed in Japanese manufacturers, has still maintained integral-architecture condition basically. Therefore, there are not any module clusters for EV parts for now.
