Abstract

The invention provides an internal formation charging process for lead storage batteries, which is divided into 22 charging and discharging stages, including 8 charging and 7 discharging times. The internal forming charging process shortens the charging and discharging time, improves the production efficiency, and improves the current efficiency. Utilization rate, the actual charged electricity is 8 to 9 times the battery capacity, which reduces energy consumption and greatly saves costs, and the process uses less current for water decomposition, high effective utilization rate of current, and higher temperature in the formation process. Low, reducing the use of circulating water for cooling.

Description

technical field [0001] The invention relates to the technical field of lead storage batteries, in particular to an internalization charging process for lead storage batteries. Background technique [0002] Compared with external formation (tank formation), the internal formation of lead-acid batteries has many advantages. Its technological process simplifies the processes of plate washing, drying, battery replenishment, and tank formation, such as loading, welding, and sheet removal. It saves a lot of energy (pure water, acid, electricity and other energy), man-hours, occupies a small area, and does not need to purchase chemical formation tank equipment and acid mist prevention equipment, and the battery cost can be reduced to a certain extent. The plate is not easily polluted by impurities, which can reduce battery self-discharge, improve battery consistency, and prolong battery life. Moreover, the internalization of the battery reduces the discharge of waste water and was...
