Description

Technical Field

[0001] The utility model relates to the field of lithium battery detection equipment, in particular to a lithium battery charge and discharge detection device. Background Technique

[0002] During the production process of lithium batteries, it is necessary to detect the charge and discharge of lithium batteries to ensure the quality of lithium batteries. At present, when the equipment for detecting the charge and discharge of lithium batteries detects lithium batteries, a set of detection equipment needs to be set up separately for each lithium battery, including a device for detecting voltage and current and a display screen for displaying the voltage and current during its charge and discharge process. This results in a low detection efficiency for the charge and discharge of lithium batteries, and requires operators to judge whether the voltage and current values during the charge and discharge process are normal. This not only has high requirements for operators, but also is prone to misdetection or missed detection. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lithium battery charge and discharge detection device, specifically to provide a detection device that can simultaneously detect the charge and discharge of multiple lithium batteries and is convenient for screening lithium batteries with abnormal voltage and current values during the charge and discharge process.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: a lithium battery charge and discharge detection device, including a detection base and a detection parameter display screen. A number of detection positions are arranged on the detection base, and a voltage and current detection module and a detection electrode sheet are arranged on each detection position. The detection parameter display screen is connected to the voltage and current detection modules of a number of detection positions through a charge and discharge detection controller.

[0005] Specifically, a heat dissipation cavity is arranged below the detection base. The upper end of the heat dissipation cavity is communicated with the bottoms of a number of detection positions, and a heat dissipation fan is arranged at the bottom of the heat dissipation cavity.

[0006] Specifically, a temperature sensor is arranged in each of a number of detection positions, and the temperature sensor is connected to the charge and discharge detection controller.

[0007] Specifically, a detection indicator light is arranged on each of a number of detection positions.

[0008] The beneficial effect of the utility model is that by fixing multiple detection positions on the base, the data of the detection process of lithium batteries at multiple detection positions can be displayed through one screen, so as to facilitate operators to judge whether the charge and discharge processes of multiple lithium batteries are normal at the same time. With the inspection indicator lights arranged on the detection positions, it can be displayed when the voltage and current values are abnormal during the charge and discharge process, further improving the detection efficiency. At the same time, a heat dissipation cavity is also arranged below the detection position and a temperature sensor is arranged on the detection position to avoid the situation that the detection result is affected by too high temperature during the charge and discharge process of lithium batteries. Description of the Drawings

[0009] Attached Figure 1 is a schematic diagram of the overall structure of the lithium battery charge and discharge detection device in the embodiment;

[0010] Attached Figure 2 is a structural diagram of the split state of the lithium battery charge and discharge detection device in the embodiment. Specific embodiments

[0011] Embodiment 1, referring to Figure 1-2 , a lithium battery charge and discharge detection device, including a detection base 1 and a detection parameter display screen 2. A plurality of detection positions 3 are provided on the detection base 1, and a voltage and current detection module 31 and a detection electrode piece 32 are provided on each detection position 3. The detection parameter display screen 2 is connected to the voltage and current detection modules 31 of a plurality of detection positions 3 through a charge and discharge detection controller (not shown in the drawings).

[0012] In this embodiment, the detection positions 3 fixedly provided on the detection base 1 are used to place lithium batteries and perform charge and discharge detection on the lithium batteries. During detection, the electrodes of the lithium battery are placed downward into the detection positions 3, so that the positive and negative electrodes of the lithium battery are in contact with the detection electrode pieces inside the detection positions. The charge and discharge detection controller controls the charge and discharge of the lithium battery through the detection electrode piece 32, and detects the voltage and current during the charge and discharge process of the lithium battery through the voltage and current detection module 31 and displays them on the detection parameter display screen 2. By dividing the detection parameter display screen 2 according to the arrangement of the detection positions on the detection base 1, the detection data of the corresponding detection positions 3 can be displayed on the detection parameter display screen 2, so as to facilitate the operator to quickly judge the relevant parameters of the charge and discharge process of the lithium batteries at different detection positions 3. In addition, detection indicator lights 33 can be provided on the detection positions 3, and the inspection indicator lights 33 among them are connected to the charge and discharge detection controller. When the voltage value or current value is abnormal during the charge and discharge process of the lithium battery, it can be displayed on the detection indicator lights 33, which is convenient for the operator to quickly judge and screen the lithium batteries with faults and improve the detection efficiency.

[0013] In addition, a heat dissipation cavity 4 is provided below the detection base 1. The upper end of the heat dissipation cavity 4 is communicated with the bottoms of a plurality of detection positions 3, and a heat dissipation fan 41 is provided at the bottom of the heat dissipation cavity 4. Since a large amount of heat is dissipated during the charge and discharge process of the lithium battery, when multiple lithium batteries are gathered together, the temperature in the vicinity will rise. By using the heat dissipation cavity 4 and the heat dissipation fan 41 at the bottom of the heat dissipation cavity 4, the lithium batteries undergoing charge and discharge detection in the detection positions 3 can be uniformly cooled, avoiding overheating of the lithium batteries and affecting the detection results.

[0014] Meanwhile, a temperature sensor (not shown in the attached drawings) can be set within the detection position, and the temperature sensor is connected to the charge and discharge detection controller. The temperature sensor can be used to detect the temperature within the detection position 3, and the temperature can be displayed on the detection parameter display screen 2 through the charge and discharge detection controller. When the temperature is abnormal, it can be discovered in time and corresponding measures can be taken to avoid problems such as damage to the lithium battery due to excessive temperature or potential safety hazards.

[0015] Certainly, the above is only the preferred embodiment of the present utility model, and it does not limit the scope of use of the present utility model. Therefore, all equivalent changes made on the principle of the present utility model should be included within the protection scope of the present utility model.
