Subscription-based electric vehicle charging management methods and systems

A subscription-based electric vehicle charging management system for use in a charging field, comprising:

• at least one electric vehicle charging station;
• and
• a server coupled to the electric vehicle charging station through a network, receiving a charging request from the electric vehicle charging station or a mobile device through the network, wherein the charging request includes at least a user identification code, searching a database to obtain a contract situation corresponding to the user identification code according to the user identification code, and determining whether the contract situation corresponding to the user identification code is in a contract expiration status or an arrears unpaid status, wherein the server instructs the electric vehicle charging station to perform a charging operation through the network when the contract situation is not in the contract expiration status or the arrears unpaid status and the server transmits a charging rejection instruction to the electric vehicle charging station through the network when the contract situation is in the contract expiration status or the contract situation is in the arrears unpaid status,
• wherein the electric vehicle charging station rejects the charging request in response to the charging rejection instruction, and wherein the server further transmits the contract situation to the electric vehicle charging station through the network when a network connection between the server and the electric vehicle charging station is connected, and the electric vehicle charging station is configured to determine whether the network is disconnected so that the electric vehicle charging station cannot connect to the server and whether a charging request is received from the electric vehicle charging station or the mobile device, and perform an offline management operation to determine whether the contract situation corresponding to the user identification code is in the contract expiration status or the arrears unpaid status in response to the charging request when the network is disconnected and the electric vehicle charging station cannot be connected to the server, and the electric vehicle charging station performs the charging operation to output power when the contract situation is not in the contract expiration status or the arrears unpaid status and rejects the charging request when the contract situation is in the contract expiration status or the contract situation is in the arrears unpaid status.

A machine-readable storage medium comprising a computer program, which, when executed, causes a device to perform a subscription-based electric vehicle charging management method for use in a charging field with at least one electric vehicle charging station and the electric vehicle charging station is connected to a server through a network, wherein the method comprises:

• receiving a charging request from the electric vehicle charging station or a mobile device through a network by the server, wherein the charging request includes at least a user identification code;
• searching a database to obtain a contract situation corresponding to the user identification code according to the user identification code by the server;
• determining whether the contract situation corresponding to the user identification code is in a contract expiration status or an arrears unpaid status by the server;
• instructing the electric vehicle charging station to perform a charging operation through the network by the server when the contract situation is not in the contract expiration status or the arrears unpaid status;
• transmitting a charging rejection instruction to the electric vehicle charging station through the network by the server when the contract situation is in the contract expiration status or the contract situation is in the arrears unpaid status;
• and
• in response to the charging rejection instruction, rejecting the charging request by the electric vehicle charging station,
• wherein the method further comprises the steps of:
• transmitting, by the server, the contract situation to the electric vehicle charging station through the network when a network connection between the server and the electric vehicle charging station is connected;
• determining, by the electric vehicle charging station, whether the network is disconnected so that the electric vehicle charging station cannot connect to the server and whether a charging request is received from the electric vehicle charging station or the mobile device;
• performing, by the electric vehicle charging station, an offline management operation to determine whether the contract situation corresponding to the user identification code is in the contract expiration status or the arrears unpaid status in response to the charging request when the network is disconnected and the electric vehicle charging station cannot be connected to the server:
• performing, by the electric vehicle charging station, the charging operation to output power when the contract situation is not in the contract expiration status or the arrears unpaid status;
• and
• rejecting, by the electric vehicle charging station, the charging request when the contract situation is in the contract expiration status or the contract situation is in the arrears unpaid status.
