摘要： The invention discloses a battery device, a detection method thereof, and a screening method and device of a battery unit. A difference between characteristic values of any two battery units in the target charge state within a first preset range is controlled. Through the difference in overpotential of different battery units, the polarization difference between different battery units is reflected, thus reflecting the consistency difference between different battery units. The solution may dynamically monitor the consistency of various battery units, which may reflect the consistency of the battery unit during use, realize the online monitoring of the battery unit, and provide guidance for use of the battery device in subsequent process.
