Problems solved by technology
[0004] At present, there are two main discharge technologies commonly used in the battery production process: one is the discharge technology based on silicon controlled rectifiers, and the discharged electric energy of this kind of equipment is returned to the public power grid, and the discharge recovery efficiency is low; the other is the use of resistance discharge. During the discharge process, the electric energy is all consumed in the form of resistance discharge, which is a big waste

Description
technical field [0001] The invention relates to the technical field of battery detection, in particular to a grid-feed type battery discharge detection device. Background technique [0002] The battery is an important part of the electric DC power supply system and the basic communication power supply system. As the backup power supply of the DC system, it is responsible for continuing to provide safe, stable and reliable power guarantee in the event of a sudden interruption of the mains power supply. Therefore, the actual capacity that the battery can provide to the load during the discharge process is of great significance to ensure the operation of the equipment. [0003] In order to accurately know the actual discharge capacity of the battery pack and solve the internal resistance increase and capacity drop caused by the solidification of the internal components of the battery pack under the long-term floating charge state, it is necessary to conduct a discharge test on ...
