Charging management method and system for improving utilization of electric resources

The invention provides a charging management method and system for improving utilization of electric resources, and the method comprises the steps: judging whether to transmit intention information to a first object or not according to the information of the number of waiting buses in a waiting region when the first object receives the charging of a corresponding charging pile; if the first object receives the cooperation option in the intention information, after the friendly object completes the first charging strategy, adding a friendly mark associated with the identity information of the friendly object into a database of the electric vehicle charging station, and if it is judged that the friendly mark exists in the multiple second objects, sending the second object to the second object; if not, the charging priority of the second object is higher than that of the other second objects without the friendly marks. The technical problem that due to the fact that the charging mode of the public charging stati
