Charging scheduling systems and methods thereof for charging devices

A charging scheduling system for charging devices for charging an electric vehicle, comprising:

• a charging device, comprising:
• a battery detection unit detecting a power status of a battery module of the electric vehicle;
• a network connection unit;
• and
• a processing unit coupled to the battery detection unit and the network connection unit, transmitting the power status of the electric vehicle through a network by the network connection unit;
• and
• a cloud management module, comprising:
• a storage unit recording electricity rate data of the charging device, wherein the electricity rate data comprises electricity prices with a TOU (Time Of Use) rate for a power company;
• a network connection unit receiving the power status of the electric vehicle via the network;
• and
• a processor coupled to the storage unit and the network connection unit, determining at least one charging period with a lower electricity price according to the electricity rate data of the charging device and the power status, and scheduling and controlling the charging of the electric vehicle by the charging device to be performed during the determined at least one charging period.
