Abstract
In this paper, I consider the automotive battery business for EV / PHV, which has come to attention in the automotive market. I pick up the Korean battery maker Samsung SDI and LG Cham’s efforts in this field. The two companies of EV / PHV automotive battery business for has been done in the relationship between different companies and business-to-business relationship in the conventional automotive market. I point out that. In the electric car market, such as EV / PHV, battery manufacturers in business-tobusiness relationships with automobile manufacturers, has built unprecedented inter-company relationship, you are affecting the future of the automotive battery manufacturer's efforts. These different companies’ relations is due to the specificity of the method of mounting a battery to be used in the EV / PHV. For this reason, in the EV / PHV, no division of labor in conventional has been built in battery procurement.
