Zusammenfassung:	The invention provides a charging system and a charging control method and device.The charging system comprises M power modules, N charging interfaces, a first switch unit, a second switch unit, a third switch unit and a control unit.The input ends of the M power modules are used for being connected with a preset power source; a first switch unit is connected between the positive and negative output ends of two adjacent power modules, a second switch unit is connected between the positive output ends of two adjacent power modules to form a first positive power line of the M power modules, and the negative output ends of two adjacent power modules are connected to form a negative power line of the M power modules. The first positive power line is connected with the positive power ends of the N charging interfaces, the negative power line is connected with the negative power ends of the N charging interfaces, and the negative output ends of the first power module to the (M-1) th power module are connected with
