Development of an intelligent lithium-ion battery-charging management system for electric vehicle

摘要

In this research, an intelligent lithium-ion battery-charging management system is proposed. The system integrates the battery monitoring and balance platform (BMBP) and charging station. According to the battery information of BMBP and the user needs, a proposed dual charging method (DCM) is used to control the charging voltage or current of charging station. The DCM contains the rapid and the smart multi-stage charging methods. In addition, the smart multi-stage charging methods depress the temperature rising during charging to protect the batteries. On the other hand, the system also provides a friendly graphic user interface on PC or smart devices for user to select the charging method and monitoring the state of batteries. The system proposes a convenient solution for both quickly or safely charging needs.
