What are the precautions for battery open circuit?
A battery is a device that directly converts chemical energy into electrical energy. It is a battery designed for rechargeability. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery. It is a type of battery and belongs to the secondary battery. Lead-acid batteries can be charged and discharged repeatedly. Its cell voltage is 2V. The battery is a battery pack composed of one or more cells, referred to as storage battery. The common one is 6V, and there are 2V, 4V, 8V, 24V batteries. . For example, the battery (commonly known as the battery) used in a car is a 12V battery pack with 6 lead batteries connected in series.
Batteries are now being used more and more widely due to various advantages and some reasons. However, many people do not know the batteries very well. Excluding the quality reasons of the batteries, generally the open circuit of the battery is a long-term process, but some batteries are not open. It is easy to be discovered in time under the existing detection mechanism. What are the precautions for battery open circuit? How much do you know about this? Today, the editor of Zhengzhou Kanglida Electronic Power Supply Co., Ltd. will give you some knowledge on this issue, and hope it will be helpful to you.
1) Periodically discharge the battery with a large current for a short time, and perform online recording of the voltage of each battery cell. On the one hand, the internal resistance of the battery can be calculated through the discharge data, and the performance of the battery can be judged; on the other hand, the load capacity of the battery can be determined. Features are checked. To screen for hidden open-circuit batteries, it is recommended that the online discharge current is not less than the maximum value of the local load current.

2) Abandon the traditional "sealed" and "maintenance-free" concepts of valve-regulated lead-acid batteries. When the capacity of the battery decreases during the operation of the battery, consider using methods such as adding repair fluid for charging and discharging activation and repair to increase the battery capacity The internal resistance of the battery is restored to the factory level, and the corrosion of the positive grid inside the battery, the drying up of the electrolyte, and the corrosion of the negative busbar are alleviated.
3) Strictly implement regular check-up annual capacity tests of battery packs, and monitor the voltage data of the battery pack and the charging and discharging process of each battery cell throughout the process, and file storage through the database. Further testing of abnormal batteries in the battery pack is screened by horizontally comparing the voltage curve of each battery cell of the entire battery pack, and the voltage change trend on the time axis of a single battery is compared longitudinally to predict the change trend of battery performance.
