Poen means POsitive ENERGY. Poen is a startup with a business model that seeks to create positive new values by reusing wasted energy resources. Poen is focusing on energy upcycle technology that transforms batteries from discarded electric vehicles into usable energy. In order to use the battery safely again, a battery diagnostic solution that accurately diagnoses the battery condition, BMS (battery protection circuit) has been developed for various applications, such as developing it according to the battery, and developing it as a different energy source. It is predicted that Poen will become a company that evaluates the remaining value of electric vehicles’ batteries by predicting the battery life of electric vehicles, not just battery upcycling companies.
