Embodiment Construction

[0014] The present invention is further illustrated below by way of examples.

[0015] Taking the most commonly used 12V10Ah lead-acid battery in the market as an example, the recycling method of unqualified batteries is as follows:

[0016] 1. Preliminary inspection: Eliminate abnormal appearance and feedback batteries with a production date of more than six months, and reuse batteries with a 5A discharge capacity of more than 90 minutes;

[0017] 2. Dismantling: Use a dismantling machine or other tools to cut the battery case according to the position of the separator in the battery barrel, remove the connecting strips, carefully take out the six pole groups, and place them in a plastic tank to prevent acid spillage. body for special recycling;

[0018] 3. Inspection: First, visual inspection, if the plate and diaphragm are not damaged, and the color is normal, then use a multimeter to detect the open circuit voltage of the pole group, and check the pole group (usually no m...

Abstract

The invention discloses a recycling method of an unqualified battery for an electric bicycle, comprising the following steps of: disassembling 12 V series unqualified batteries with production time less than 6 months and returned to factories through market feedback; selecting qualified polar groups from six polar groups disassembled from each battery according to a certain standard; then detecting and sorting the qualified polar groups; and then reassembling the polar groups in same sorts into new batteries used for the service replacement of the market feedback batteries by referring to the requirements of a normal battery assembly process. The recycling method has the advantages of resource saving, environmental protection, high application value, outstanding economic and social benefit, easy operation, normative process and suitability of popularization and use.

Description

technical field [0001] The invention relates to a method for reusing unqualified batteries for electric bicycles, which is applied in the fields of electric bicycle battery production and after-sales service. Background technique [0002] Lead-acid batteries are widely used, especially in recent years, with the rapid development of electric bicycles, the scale of lead-acid batteries used in electric bicycles has exploded. [0003] The nominal voltage of an electric bicycle battery is usually 12V, which consists of 6 individual pole groups with a voltage of 2V (the so-called pole group is a combination of positive and negative plates stacked cross-stacked and separated by a diaphragm in the middle) through an internal series combination. become. The 6 pole groups are installed in the battery barrel with 6 separate cavities, and each pole group actually forms a battery with a nominal voltage of 2V. During the use of the battery, the electrode groups are only connected in ser...
