The present invention belongs to the charging control technology field, and provides a charging system. In the invention, the charging system comprises a control module, N charging modules, N switch modules and N temperature detection modules, wherein N is larger than 1 and a positive integer; when the control module determines that a charging device is in a state to be charged, the control modulecontrols an mth switch module to be closed to enable an mth charging module to charge the charging device, when the working time of the mth charging module is larger than a preset time or the temperature of the mth charging module is larger than a preset temperature, the control module controls the mth charging module to stop work and controls an (m+1)th charging module to charge the charging device, wherein 1<=m
