Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment testing technology, and in particular to an energy storage battery charge and discharge testing device. Background Technology

[0002] With the rapid development of the energy storage industry, energy storage batteries, as core energy storage components, directly affect the stability and safety of the entire energy storage system through their charging and discharging performance. Therefore, accurate detection of the charging and discharging status of energy storage batteries is particularly important. Currently, there are energy storage battery charging and discharging detection devices on the market.

[0003] Two main problems often exist during the testing process: First, the battery is not securely fixed. Due to the size differences between different specifications of energy storage batteries, existing testing devices cannot securely clamp batteries of different specifications. During testing, the battery is prone to displacement or shaking, resulting in poor contact between the battery and the testing circuit, which in turn affects the accuracy of the test data. Second, the fixing and heat dissipation of the testing instrument are inadequate. Testing instruments are often placed directly or simply fixed. During the testing process, the instrument is prone to loosening, and the heat generated by the instrument cannot be dissipated in time. This not only shortens the service life of the instrument but may also affect the testing accuracy due to high temperature. Therefore, it is necessary to design an energy storage battery charge and discharge testing device to solve the above problems. Utility Model Content
