Description
Summary:碩士 === 國防大學理工學院 === 電子工程碩士班 === 105 === Traditionally chargers of high-capacity Li-ion batteries for electrical buses only provide fixed charging method, such as constant voltage or constant current, and lack of parameters monitoring mechanism while batteries are charging. Hence, a high temperature rising during charging process may occur and reduce the life of batteries. In order to solve this problem, this paper develops an integrated battery-charging management system and proposes an intelligent charging algorithm to diminish the temperature rising situation. In addition, we design a subsystem integrated various communication protocols between batteries and chargers to make the system easily sends charging command to the batteries and acquires the parameters from the battery management system. The system can automatic adjust the charging parameters according to the feedback data from batteries to eliminate the temperature rising for the sake of extending the life of battery. Finally, we design an APP for users to monitoring and control the conditions of batteries remotely
