The invention provides an intelligent power distribution control method of a charger power supply module. According to a loading condition of a module in a system, a new module is intelligently started up or is dormant and the method is circularly executed until the module runs in an optimal state; meanwhile, a module with the shortest accumulated running time is firstly started up at each time of starting up; when power is increased, modules are started up in sequence according to the accumulated running time of the modules from short to long; when the power is decreased, the modules stop running in sequence according to the accumulated running time from long to short; the module with the shortest accumulated running time is dormant finally, so that balanced control on the running time is realized.
