The utility model discloses a fill electric pile based on air -cooled system of module of charging control, including charging module, controller, collection board, relay and fan, wherein, the temperature data collection chip of the module of charging is connected to the controller, receives the temperature value of the module self of charging, and the controller is sent a signal for the collection board, gathering the board and sending a signal for the relay, the auxiliary contact of relay controls the start -up of fan or stops. Can realize that the accurate control fan opens the purpose of stopping, compare the temperature controller scheme temperature controller only in prior art, as long as the temperature controller has broken, perhaps the temperature inaccurate will cause can't the accurate control fan to open stop, and one filled that electric pile is inside to have multiple modules, even a module is damaged, does not also influence and send the temperature in other modules.
