Abstract

The invention relates to a square wave voltammetry battery sorting method and device. The device comprises an intelligent controller (1), a constant potential rectifier (2), a measured battery (3), a current sensor (4) and a sampling / retaining appliance (5). The invention simultaneously provides the square wave voltammetry battery sorting method. The square wave voltammetry battery sorting method is characterized in that a measurement process is circularly composed of a series of small steps, a delta Ep forward direction electric potential with one pulse height is applied on the battery and can keep constant in each circulation, the current sampling is preformed after special time t, a delta Ep negative direction electric potential with one pulse height is applied on the battery and can keep constant, the current sampling is preformed after special time t, then the potential changes a small range delta Es, the next circulation begins, a changing curve of the current to the voltage in the whole circulating process is recorded, and same batteries are marked in the same kind according to the changing curve.

Description

technical field [0001] The invention relates to a square wave voltammetry battery sorting method and device, belonging to the field of battery detection. Background technique [0002] The currently commonly used battery classification methods generally need to measure the parameter changes in the battery charging and discharging process as the basis for battery sorting. However, these methods often take a long time and consume a lot of power during the sorting process. The present invention proposes a The square-wave voltammetry battery sorting method and device can realize rapid sorting of batteries, and hardly consume electric energy, and the sorting efficiency is obviously improved. Contents of the invention [0003] The present invention aims to provide a square wave voltammetry battery sorting method and device, which can quickly sort batteries without long-term charging and discharging operations. [0004] To achieve the above-mentioned purpose, the present inventi...
