The battery technology innovations have been created for some applications, including electric vehicle and energy storage in Indonesia. Unfortunately, the study about technopreneurship for commercializing the innovations is a relatively unexplored field and studies the relationship between the innovation system and technopreneurship seen from commercialization’s point of view are virtually nonexistent. This paper provided a study of a technopreneurship model that is suitable for a technological, based on comparative research, some innovation of battery technology products. The article highlights common challenges and barriers faced by inventors and R& D centers in developing technological entrepreneurship along with its benefits for them. This is a comparative study based on case studies. The cases are diligently selected to examine a framework of technopreneurship and innovation system approach. The analysis was conducted by referring to the technopreneurship and innovation system approach to understanding the process of innovation management at the relevant technology transfer offices (TTO) and how the technopreneurship model is applied. The paper provides an insight into how technology transfer offices (TTO) organize and manage innovation activities with the technopreneurship model and how the constraints of technology commercialization on battery technology innovations.
