Problems solved by technology

In the internal formation charging, the temperature is not easy to control, and the charging efficiency is low. Most manufacturers solve this problem by prolonging the charging time and increasing the charging capacity, but this leads to a long production cycle and increased production costs. Problem; some manufacturers try to increase the charging current per unit time, but the battery will seriously affect its cycle life due to high temperature
At the current level of technology, it is difficult to charge for a short time without affecting battery performance.

Description

technical field [0001] The invention relates to a storage battery charging technology, in particular to a fast-charging acid circulation system for a lead-acid storage battery. Background technique [0002] The internal formation charging technology of the battery is a technology in which the plates are formed and charged in the battery shell, with low cost, low pollution, and less harm to workers than external formation. In the internal formation charging, the temperature is not easy to control, and the charging efficiency is low. Most manufacturers solve this problem by prolonging the charging time and increasing the charging capacity, but this leads to a long production cycle and increased production costs. Problem: Some manufacturers try to increase the charging current per unit time, but the battery will seriously affect its cycle life due to high temperature. At the current level of technology, it is difficult to charge for a short time without affecting battery perf...
