Abstract: Subscription-based electric vehicle charging management methods and systems are provided. A server receives charging request with at least a user identification code from an electric vehicle charging station or a mobile device through a network. The server searches a database according to the user identification code to obtain contract situation corresponding to the user identification code and determines whether the contract situation is in a contract expiration status or an arrears unpaid status. When the contract situation is not in the contract expiration status or the arrears unpaid status, the server instructs the electric vehicle charging station to perform a charging operation. When the contract situation is in the contract expiration status or the arrears unpaid status, the server transmits a charging rejection instruction to the electric vehicle charging station. In response to the charging rejection instruction, the electric vehicle charging station rejects the charging request.

Abstract: Electric vehicle charging management methods and systems are provided. First, a server receives a candidate charging request respectively from each of candidate charging stations or candidate mobile devices via a network. According to the candidate charging requests, at least one first charging station is selected from the candidate charging stations, and the first charging station is instructed to perform a first charging operation with an upper power limit value. The server sets the candidate charging requests of the candidate charging stations other than that of the first charging station to a pending state. When the first charging status information corresponding to the first charging operation meets an energy management condition, the server selects at least one second charging station from the candidate charging stations according to the candidate charging requests, and instructs the second charging station to perform a second charging operation with the upper power limit value.

Abstract: Charging scheduling systems and methods for electric buses for use in at least one electric bus and a cloud management module are provided. First, a current location of the electric bus is obtained by a positioning unit of the electric bus and a current power state of a battery module of the electric bus is detected by a battery detection unit of the electric bus. A route corresponding to the electric bus is obtained by the cloud management module, wherein the route includes at least one charging point, and records a location of the charging point and a charging efficiency of at least one charging equipment installed at the charging point. Then, the cloud management module determines whether the electric bus needs to be charged with the charging equipment at the charging point according to the current location and the current power state of the electric bus.
