Embodiment Construction

[0024] Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary, and embodiments of the present invention are described in detail below.

[0025] For the current decommissioned battery sorting method, it needs to be carried out under the condition of well-equipped equipment, and there are situations where the site and equipment are limited. Finally, it is impossible to sort the decommissioned batteries, which improves the efficiency of decommissioned battery sorting.

[0026] figure 1 It is a flow chart of a step-by-step utilization sorting method for decommissioned batteries according to an embodiment of the present invention, such as figure 1 As shown, the step-by-step utilization and sorting method for decommissioned batteries in the embodiment of the present invention includes at least step S1, step S2 and step S3, specifically as follows.

[0027] Step S1, detecting the thickness and A...

Abstract

The invention provides a retired battery echelon utilization sorting method and system, and the method comprises the steps: detecting the thickness and AC resistance of a retired battery; calculatingthe capacity value of the retired battery through a battery capacity fitting formula according to the thickness of the retired battery and the alternating current resistance; and determining a qualified retired battery according to the capacity value. According to the retired battery echelon utilization sorting method, the retired battery thickness and the alternating current resistance are detected, the capacity value of the retired battery is calculated by utilizing the battery capacity fitting formula, the retired battery with the qualified capacity value is obtained, and the limitation ofa site and equipment on retired battery sorting is reduced, so that the sorting popularization rate of the retired battery is improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a sorting method and system for step-by-step utilization of decommissioned batteries. Background technique [0002] As the core component of an electric vehicle, the battery needs to be replaced when its capacity drops to the point that it cannot meet the form requirements of the electric vehicle. Sorting the replaced batteries is a problem that needs to be solved at present. [0003] At present, when sorting batteries, it is necessary to assume that the site is sufficient and it is carried out in a well-equipped situation, so the implementation will be limited by the site and equipment. If battery recycling is carried out outdoors, the battery sorting plan will be limited due to insufficient site conditions, resulting in that battery sorting cannot be greatly promoted. Contents of the invention [0004] The present invention aims to solve at least one of the technical prob...
