Description

Technical Field

[0001] The invention relates to the technical field of battery detection, and in particular to an online discharge detection device for a battery. Background Art

[0002] The battery plays a vital role in the quality and reliability of the DC power supply system of the access network. As it is a consumable item with a limited service life, on the one hand, it is required to strengthen the maintenance and management of the battery to extend its service life, and on the other hand, it is required to replace the battery in time before the end of its service life to ensure the normal operation of the system. The common battery problems in actual use are mainly manifested as insufficient capacity, poor consistency of battery pack charging and discharging process, premature battery life attenuation, acid leakage, etc.

[0003] At present, most of the battery discharge detection devices on the market increase the labor consumption when carrying the battery to the device when discharging the battery. When detecting the battery, only the same type of battery can be detected and it cannot be fixed. It is too single and generates too much heat during the operation, which affects the detection data. Based on these problems, Chinese patent CN214703907U discloses an energy-saving battery discharge detection device. By setting a heat dissipation fan blade and an adjustment blade, the device body can be adjusted to dissipate heat. The heat dissipation efficiency can be adjusted according to different needs to reduce the power consumption of the battery. By setting an electric push rod and a pulley, the support plate can be moved, which is convenient for placing the battery inside and improving safety. By setting an adjustment block and an adjustment slot, the copper head terminal can be adjusted to adapt to batteries of different sizes, directly contact the battery, and save energy and safety. By setting a moving block and a fixing plate, the battery is fixed to avoid the movement of the battery, which affects the detection and improves the accuracy of the detection.
