Battery cell precision calibration tool for formation and capacity grading equipment

Abstract

The invention discloses a battery cell precision calibration tool for formation and capacity grading equipment in the technical field of formation and capacity grading calibration, and the tool comprises a tool box body which is a fully-closed ventilated hollow box body, wherein two calibration graduated scales and two electrode plates are respectively arranged at the top of the tool box body; the two calibration graduated scales are arranged on the two opposite side edges of the top of the tool box body in parallel, quick insertion and quick connection can be achieved when the square battery cell formation and capacity grading equipment is detected, electricity taking and data connection of devices of the equipment can be completed only by aligning the device with an electricity taking port of the formation and capacity grading equipment and pushing the device in, so the installation is very convenient. And the wireless router and the universal meter are integrated in the device, so the device can more conveniently detect the data of the formation and capacity grading equipment, and all detection devices are cooperatively connected and mounted in an integral protection box body, so that the circuit is more regular.

Description

technical field [0001] The invention relates to the technical field of chemical composition capacity calibration, in particular to a cell precision calibration tool for chemical composition capacity equipment. Background technique [0002] When the square lithium battery is hot-pressed and divided, it is necessary to pass a large current between the positive and negative electrodes of each battery for charging and discharging. By charging and discharging the cells, the data of the capacity and internal resistance of these cells can be analyzed. , to determine the quality level of the battery cells, and group them to select batteries with the same electrical parameters for series and parallel applications. When the forming capacity equipment is in the process of charging and discharging, the current will encounter resistance in each small section in the process of flowing in the circuit, and a certain voltage drop will be generated. Therefore, when the battery is formed and d...

Problems solved by technology

[0004] The defects of the existing technology are mainly manifested in: 1. The operation is cumbersome and the wiring is messy. The tooling currently used in the market needs to be manually connected to the 220V interface to supply power to the tooling instrument outside the device, and then through the cable, the network port and the tooling panel. 2. The exposed cables are messy and unsightly, and a tooling trolley is required to place instruments and meters. The instruments and meters are separated from the tooling panel, which is inconvenient to operate; 3. Poor compatibility. Most of the tooling used in the market is in the form of a panel. Although it is compatible with the distance between the poles of the battery core, the number of channels, and the distance between the front and rear probes, the size of the panel is a fixed structure, and the compatibility is poor. It is very inconvenient to equip a fixed panel separately, and when the spacing between the poles of the batteries is slightly different, the structure of this type of panel is not compatible, that is, not only the size of the panel needs to be equipped separately, but also the spacing between the poles of the batteries. It is also necessary to re-match a panel, and data transmission also requires a separate data cable to be used by an external monitoring computer, which is very inconvenient to use
