Abstract

The invention discloses a container formation method for a lead-acid storage battery for an electric road vehicle. 27 charging and discharging stages are divided. The period comprises eight times of discharging, one time of standing and one time of capacity checking and matching, the maximum charging current is 0.30 C3 to 0.35 C3, and the minimum charging current is 0.05 C3 to 0.1 C3. The lead-acid storage battery is charged and discharged for multiple times, and the electric quantity charged each time is greater than the electric quantity discharged subsequently. The method provided by the invention can effectively reduce the concentration polarization phenomenon and reduce the damage to the crystal structure of the active substance on the polar plate, thereby prolonging the cyclic service life of the lead-acid storage battery. Calculated according to GB / T32620.1-2016 regulations, the cycle life of the lead-acid storage battery prepared by the method is longer than 400 times, and theinitial capacity of the lead-acid storage battery is not lower than 100% (in terms of rated capacity).

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to an internal formation method of lead-acid batteries for electric road vehicles. Background technique [0002] There are many existing internalization charging methods, such as the Chinese patent document whose publication number is CN101853968A discloses a kind of standby lead-acid battery internalization charging method. The charging time is 95-105 hours, during which 2 times of discharge, 6 times of charging and 1 time of resting have been performed, and the maximum charging current is 0.15C 10 , minimum charge current 0.03C 10 . [0003] The Chinese patent literature with the publication number CN104577217A discloses a process for the internal formation of lead-acid batteries for energy storage; it includes the following steps: S1: add acid to the lead-acid battery and leave it for 1 to 2 hours; S2: add acid to the lead-acid battery with 0.15 ~0.30C constant cur...
