The invention relates to an automatic split charging method used for a concentrator narrow-band carrier wave module. According to the automatic split charging method, automated logistics and automaticstorage are achieved, the blank of state grid carrier wave module metering automatic bagging is avoided, the manual destacking and stacking time can be saved, and a person is liberated from heavy destacking and stacking; and meanwhile, the bagging speed is increased, the accuracy is improved, the bagging cost is saved, the space using rate is improved, people participation is reduced, and the product bagging efficiency can be greatly improved.
