example 1

[0066] Example 1: For a 12V 100AH ​​battery, the discharge detection capacity is now required, and an appropriate discharge current value is selected, as well as the corresponding theoretical value of the theoretical end-of-discharge voltage. Check the attached table, the first row is the discharge capacity of the 100AH ​​battery, according to the table shows:

[0067] Under normal circumstances, a 100AH ​​battery with a capacity of 2 volts can be discharged at a current of 10A for 10 hours, and the discharge termination voltage is 1.8 volts. In this example, the battery is 12 volts, that is, six 2-volt batteries are connected in series, so after continuous discharge for 10 hours, the end-of-discharge voltage is 1.8×6=10.8 volts.

[0068] In order to save time, we use a large current discharge, generally using a current several times the battery capacity for discharge. Check the attached table, the 100AH ​​battery is discharged with a current of 50A. Under normal conditions, ...

example 2

[0070] Example 2: The discharge current value and termination voltage value of a battery with a rated capacity of 5 hours is 12V 100AH, that is, a battery with a capacity of 100AH ​​and a capacity of 2 volts under normal conditions can be discharged at a current of 20A for 5 hours, and the discharge termination voltage is 1.8 volts. In this example, the battery is 12 volts, that is, six 2-volt batteries are connected in series, that is, after the battery is continuously discharged for 5 hours, the end-of-discharge voltage is 1.8×6=10.8 volts.

Abstract

The exploited renovating technology for irreversible sulfuration of lead-acid accumulator applies nano synthesis technology and leading theory, and comprises steps as following: detecting cell state, determining ingredient and proportion for recovery liquid, knocking the lead sulfate crystal by a match-cell renovation device, opening ion channel to full discharge and activate original active material.

Description

Technical field: [0001] The invention relates to the technical field of electrochemistry, in particular to the repair technology of a secondary battery, that is, a lead-acid storage battery. Background technique [0002] At present, there are two methods of repairing and maintaining lead-acid batteries in the world. One is American products (the product patent numbers are: 4871959, 5276393, 5491399), called pulse battery protectors, which rely on solar energy or the battery itself. The generated electricity produces a DC pulse whose frequency is the same as the natural frequency of the sulfuric acid compound molecule of the battery, so resonance is generated, and the sulfuric acid compound, namely sulfate, is decomposed and separated from the battery plate, but the repair is only about 80% . The second is the activator of the lead-acid battery developed by Japan Haotek Co., Ltd., which mainly uses the added activator to decompose the sulfate and separate it from the battery...
