It is the space for having survival.
The electronic automobile-used lead-acid battery developing direction that can be peeped at present is mainly lead charcoal, and high-ratio surface is added in cathode
Product modified activated carbon, can effectively solve the problems, such as the irreversible sulfation of cathode, so that battery life is extended, while making lead
Sour battery has the double grading of capacitor and battery, the high capacity density of existing battery, and has the high charge ability to accept of capacitor
With the long life etc., and cryogenic property also obtains biggish improvement；But the factor for restricting battery life still has, and passes through
The discovery of common electric vehicle battery is dissected, cathode sulfation problem is implicitly present in, but the dominant failure mode of battery is still anode
Active material softening, therefore the improvement of anode is similarly important, prevents the mode of positive material(PAM) softening relative efficiency from having two
Kind, one, improve mixing paste and cured temperature in production process, improve the ratio of four basic lead sulphates in positive active material, two,
Four basic lead sulphates are directly added in mixing paste, so optimum method is, two ways is used together.
To embody the characteristic of lead carbon battery quickly-chargeable and exploring lead carbon battery quick charge in the reality of electric automobiles
Border application, needs to test the performance of battery, the period mistake of original battery testing mode (100%DOD detection) detection
It is long, it can only accomplish within general 24 hours 1.8-2.0 circulation, efficiency is relatively low, is not able to satisfy needs of production, and be unable to body
The characteristic of existing quickly-chargeable battery.
Summary of the invention
Technical problem to be solved by the present invention lies in providing, a kind of method is simple, at low cost, high-efficient, and can embody electricity
The quickly charging battery cycle life detection method of pond quick charge capability.
The technical problems to be solved by the invention are realized using following technical scheme:
A kind of quickly charging battery cycle life detection method, steps are as follows for specific method:
