Description
Technical Field
The invention relates to a matching method of lead-acid storage batteries.
Background
Lead-acid batteries are currently widely used worldwide in view of their proven high performance, low cost, easy recycling and reliable safety. After the lead-acid storage battery is assembled, the battery needs to be acidified to form a matched set. During the grouping process, the discharge end voltage of a battery is higher or lower than the voltage of the whole battery, so that the battery cannot be grouped and cannot be delivered, and the batteries are mainly caused by the inconsistency of the capacity. The batteries are generally subjected to acidification and then matched, so that the matching rate of the batteries is not high, a large number of treated batteries wait for the next treatment, and the working efficiency is low. Repeated formation can affect the uniformity of the cells and thus the battery's cycle life.

Further, the formation treatment process comprises the following steps: charging for 6-15 hours at a current of 0.02-0.06C; discharging at 0.5C ampere current with the discharge voltage of 10V, and performing a discharge meter on 6 single-cell batteries, wherein the voltage of each battery is controlled to be 10.3-10.8V when the meter is used; classifying according to the fact that the voltage difference of the termination voltage is less than 0.1V-0.3V, placing the classification in the same path, and performing constant voltage current limiting charging for 8-15 hours, wherein the charging current is 3 amperes, and the charging voltage is 15V-15.5V; standing for 24-48 hours, measuring open-circuit voltage, and matching.
The matching method of the lead-acid storage battery greatly improves the matching efficiency.
Detailed Description
The present invention will be further described with reference to the following specific examples.
The method for improving the battery matching rate comprises the following steps: after the batteries are subjected to acidification formation and matching, the batteries which cannot be matched according to a matching process are firstly classified, the batteries with the discharge termination voltage of 7.5V-9V and the open-circuit voltage of 13.00V-13.30V are screened and classified, the batteries with the termination voltage higher than 7.5V-9V and the open-circuit voltage higher than 13.00V-13.30V are screened out, and the batteries with the closer termination voltage are placed on the same circuit for formation treatment. The formation process comprises the following steps: charging for 6-15 hours at a current of 0.02-0.06C; discharging at 0.5C ampere current with the discharge voltage of 10V, and performing a discharge meter on 6 single-cell batteries, wherein the voltage of each battery is controlled to be 10.3-10.8V when the meter is used; classifying according to the fact that the voltage difference of the termination voltage is less than 0.1V-0.3V, placing the classification in the same path, and performing constant voltage current limiting charging for 8-15 hours, wherein the charging current is 3 amperes, and the charging voltage is 15V-15.5V; standing for 24-48 hours, measuring open-circuit voltage, and matching.
After the batteries which cannot be matched and assembled are screened and classified, the batteries are secondarily formed through small current, and the formation of the pole plates in the batteries is guaranteed. The batteries are classified secondarily according to the termination voltage, so that each battery can be fully charged in the constant-voltage charging process and cannot be excessively dehydrated, and the consistency of the assembled batteries is ensured.
