Abstract
The disclosure provides 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 within a preset range is controlled. The characteristic value reflects the difference between polarization internal resistances of different battery units, thereby reflecting the consistency difference between different battery units. The solution can dynamically monitor the consistency of each battery unit in the battery device, which can reflect the consistency of the battery unit during the usage process to implement the online monitoring of the battery unit, thereby providing guidance for the subsequent use of the battery device.
