SERIES FORMATION SYSTEM

The present application relates to the technical field of secondary battery manufacturing, and in particular to a series formation system. The series formation system comprises a power source module and at least two formation modules, wherein the power source module is connected to the at least two formation modules in series, the at least two formation modules are connected in series, the power source module is used for supplying power to the at least two formation modules, and each formation module comprises a formation control circuit and a battery cell; and the formation control circuit is electrically connected to the battery cell, and the formation control circuit is used for controlling the magnitude of a voltage applied to the battery cell by means of the power source module and/or the magnitude of a current flowing through the battery cell, such that the battery cell switches between a constant-current charging mode and a constant-voltage charging mode. The problems in the prior art of low formation efficiency, excessively high cost and low formation quality are solved, such that the formation efficiency is greatly improved, the cost is reduced, and the product quality is improved.
