The invention discloses a cell phone APP based power supply management system for motor-pumped wells. The system includes a physical structure and a data structure. According to a data classification rule of State Grid Corporation of China, the data of the data structure is divided into two levels. The first level includes structured data and unstructured data. The second level includes codes, service data and flow data divided from the structured data, and file data, media data and buffer data divided from the unstructured data. The physical structure is composed of a production application server, a production database server, a query database server, a history database server, a testing application server, a testing database server, an interface server, a read-write card dynamic base, a power APP, a power intranet communication channel and other related service equipment. According to the invention, seamless connection and flexible selection of two methods including remote charge control and local charge control are realized, so that multiple power purchase channels and multiple payment methods are provided, and customized demands of users are met.
