Embodiment 1

[0069] like figure 1 Shown, in the low-concentration acid tank 12, packing density is 1.04g / cm 3 ~1.05g / cm 3 The low-concentration sulfuric acid, packing density in high-concentration acid tank 13 is 1.28g / cm 3 of high concentration sulfuric acid.

[0070] Continuous injection density of 1.04g / cm in multiple battery cases 3 ~1.05g / cm 3 A plurality of raw plate storage batteries are obtained after sulfuric acid, and then the raw plate storage batteries are connected to figure 1 In the chemical conversion device shown, close the second valve 13a, open the first valve 12a at the same time, open the pneumatic diaphragm pump 16 and the first circulation pump 12b, and the continuous circulation density in the raw plate battery is 1.04g / cm 3 ~1.05g / cm 3 sulfuric acid for 1 to 2 hours. Since the rising plate absorbs sulfuric acid, the specific gravity of the sulfuric acid in the battery will decrease, so after circulating the low-concentration sulfuric acid in the battery for 1...

Abstract

The invention discloses a charging and discharging method on storage battery formation, which comprises the following steps: a) the storage battery is charged for the first time at a first time, the electric quantity charged into a pole plate is 1.9 times to 2.1 times of the rated electric quantity of the storage battery and the first time is 6.5h to 7.5h; b) the storage battery is discharged for the first time; c) the storage battery is charged for the second time at a second time, the electric quantity charged into the pole plate is 1.4 times to 1.5 times of the rated electric quantity of the storage battery and the second time is 4.5h to 5.5h; d) the storage battery is discharged for the second time; and e) the storage battery is charged for the third time at a third time, the electric quantity charged into the pole plate is 4.0 times to 4.5 times of the rated electric quantity of the storage battery and the third time is 2.5h to 3h. Compared with the prior art, the result of the charging and discharging method shows that the charging and discharging time can be effectively shortened and the content of PbO2 of a positive plate can be caused to reach above 88 percent by choosing appropriate time to discharge for at least two times in the charging process, thus shortening the formation time of the storage battery effectively.

Description

technical field [0001] The invention relates to storage batteries, in particular to a storage battery formation charging and discharging method, formation method and formation device. Background technique [0002] Lead-acid batteries are an important power source for battery electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. In the preparation process of the storage battery, the formation process is an important step. The formation refers to electrolysis of the raw plate in dilute sulfuric acid solution, and through oxidation and reduction reactions, the lead monoxide on the positive plate is converted into The process of changing lead dioxide and changing the lead monoxide of the negative plate into sponge-like metallic lead. [0003] Under the traditional technology, when the battery is formed, the acid solution with a higher specific gravity is injected into the battery first, and the specific gravity of the acid solution is adjusted to 1.04-1.0...
