The adjusting circuit is connected with the plurality of battery cells which are connected in parallel and is connected with the charging and discharging circuit, the adjusting circuit comprises a plurality of switch modules, each switch module corresponds to one battery cell, and the switch modules are connected with the battery cells and the charging and discharging circuit; the control module is connected with the plurality of switch modules, preset equalization parameters are stored in the control module, and the equalization parameters comprise the corresponding relation between the voltage values of the battery cells and equalization currents; and the sampling module is connected with the control module and is used for acquiring the voltage value of each battery cell, and the control module adjusts the current value of the current flowing through the switch module according to the voltage value of each battery cell and the equalization parameter, so that the current values among the plurality of battery cells reach the equalization current.

Description

technical field [0001] The application relates to the field of circuit technology, in particular to an adjusting circuit, a device, a method, an electronic device and a nonvolatile computer-readable storage medium. Background technology [0002] At present, some electronic devices are powered by parallel cells. The primary problem faced by parallel cells is how to deal with the relationship between path impedance and shunt between multiple cells and charging management and regulation circuit. Due to the inconsistency between cells, the voltage of each cell path is inconsistent in the process of charge and discharge, which makes it difficult to achieve the optimal performance of parallel cells. For example, some cells are fully charged, but the power of some cells is much worse than that of others. summary of the invention [0003] The embodiment of the application provides an adjusting circuit, a device, a method, an electronic device and a nonvolatile computer-readable storage ...
