Description

Technical Field

[0001] The utility model relates to the technical field of storage batteries, in particular to a storage battery charging and discharging test device. Background Art

[0002] Battery refers to a general term for all chemical energy batteries that can be recharged and used repeatedly after the power is used to a certain extent. It is also called rechargeable battery. In practical applications, in order to understand the specific situation of the battery, it is necessary to use a battery charge and discharge test device to test the battery. The battery charge and discharge tester is specially designed for battery pack verification discharge experiments, capacity testing, daily maintenance of battery packs, project acceptance and other DC power supply load capacity tests.

[0003] A multi-mode battery charge and discharge test device with a Chinese authorized announcement number of CN217639448U is provided with an overheat protection structure. When the temperature inside the detector body is too high or a short circuit occurs and a fire occurs, the thermal switch will disconnect the first circuit. At this time, since the first circuit is disconnected, the power switch will automatically switch to the second circuit, so the electric telescopic rod starts, driving the closing plate to block the air intake grid and close the air intake. While the internal components of the detector are powered off, the fan group is still working, continuously extracting the air in the detector body to reduce the oxygen content in the detector body. As the air is extracted, the air pressure in the detector body decreases, and the flame will follow the airflow to the outer room. However, due to the setting of the protective groove and the reflux groove on the protective plate, the flame that can be emitted each time is very small and can be successfully extinguished. The flame retardant net is flame retardant, and the two work together, the fire will soon be extinguished due to insufficient oxygen content. However, this patent still has certain shortcomings when used. The photovoltaic room or photovoltaic base station uses a switching power supply to power the equipment, and also charges the battery pack; after the battery pack is fully charged, it is switched to floating charge. The floating charge is to compensate for the loss of battery self-discharge, so that the battery remains fully charged to ensure that the battery can supply power at full load during a power outage; the battery is running in a floating charge state for a long time. The battery is in a floating charge state for a long time, which will damage the battery's service life. Therefore, the battery needs to be maintained regularly, but since the communication base stations are located in the wild, manual maintenance is extremely inefficient. Therefore, we propose a battery charge and discharge test device to improve the above problems. Utility Model Content
