It it is the space having survival.
The electric motor car lead-acid battery developing direction can peeped at present is mainly lead charcoal, adds high-ratio surface in negative pole
Long-pending modified activated carbon, can effectively solve negative pole irreversible sulfation problem, make battery life be extended, make lead simultaneously
Acid battery has the double grading of electric capacity and battery, the high capacity density of existing battery, has again the high charge ability to accept of electric capacity
With the long life etc., and cryogenic property also obtains bigger improvement；But the factor of restriction battery life yet suffers from, and passes through
Dissecting common electric car battery to find, negative pole sulfation problem is implicitly present in, but the dominant failure mode of battery is still positive pole
Active substance softens, and therefore the improvement of positive pole is the most important, prevents the mode of positive material(PAM) softening relative efficiency from having two
Kind, one, improve in production process and the temperature of cream and solidification, improve the ratio of four basic lead sulphates in positive active material, two,
Directly adding four basic lead sulphates when with cream, so optimum method is, two ways uses together.
For embodying the characteristic of lead carbon battery quickly-chargeable and exploring the lead carbon battery quick charge reality in electric automobiles
Border is applied, and needs to test the performance of battery, the cycle mistake that original battery testing mode (100%DOD detection) detects
Long, within general 24 hours, 1.8-2.0 circulation can only be accomplished, efficiency comparison is low, it is impossible to meet needs of production, and can not body
The characteristic of existing quickly-chargeable battery.
Summary of the invention
The technical problem to be solved is to provide a kind of method simple, and low cost, efficiency is high, and can embody electricity
The quickly charging battery cycle life detection method of pond quick charge capability.
The technical problem to be solved realizes by the following technical solutions:
A kind of quickly charging battery cycle life detection method, concrete grammar step is as follows:

10-15 minute, then hold inspection electric discharge；
(3) to carrying out the small area analysis constant voltage normal charge of a long period after step (2) charge and discharge cycles 49 times, then
Proceed to hold inspection electric discharge, to detect the 2hr capacity of battery under normal charging condition, be so far one group of 50 circulation, when one group
Circulation proceeds by next loop test organized followed by from step (2) after finishing, until battery end of life.
After the big electric current constant-voltage charge of step (2) about 1 hour, or turn the relatively low constant voltage charging of small area analysis 1 hour again.
Before step (1) first carries out normal charge to lead-acid battery, lead-acid battery is carried out constant current pre-arcing and has processed,
Constant current is 1.0I2A, voltage≤1.80V/ monomer, this step is not involved in circulation.
In step (1), the electric current of normal charge is 0.2-0.4I2A, voltage is 2.4-2.6V/ monomer, and the charging interval is 10
Hour, electric current≤0.05-0.06A during termination.
