Description
Technical field
The present invention relates to lithium battery pairing fields more particularly to a kind of more battery core internal resistances to match aging comprehensive detector.
Background technique
Just go out lithium battery when quality 1 year can also with, nowadays lithium battery, battery core industry simply five can spend eight
Door, it is A product, B product which is hard to tell at all, and also disorderly, highly competitive, quality problem is impossible to guard against, has both made completely new electricity for price
Pond take hand and problem the more, be most difficult to is exactly internal resistance, how many with charging because lithium battery internal resistance and capacity have relationship
Have a relationship, however new internal resistance of cell difference it is also larger, so to assemble new battery also difficult, worry more problems after sale because
Survey at present internal resistance can only a test, several hundred batteries are arrived in face of all ten, why with can internal resistance is unified consistent.
It is found by many years Maintenance Cases: repairing ten batteries, nine are all said that effect pays no attention to phase, due to no relevant device, are made
It can not be continued to use at a large amount of subscription rate battery packs, predict the year two thousand twenty Chinese automobile electric power according to China Automotive Technology & Research Center
The problem of accumulative scale for reporting measurement to be up to 120,000-17 ten thousand tons of battery, battery recycling etc., also will be more and more prominent, once
Million even ten million scale is formed, then old and useless battery bring rear end pollutes again how this is handled.
Since used batteries single battery can continue to use several years, but so extensive old and useless battery, how can be by
Single battery equipment is used up, so unique channel is exactly to repair recombination, then problem is that recombinating battery pack is how difficult
Difficulty is unable to complete at all at present, is completed in time, and completely new new battery price is reached in expense, so a large amount of at present waste and old
Where battery disappears without a trace.
Electric car, electric bicycle, battery run not far, off-capacity, power-off and using 1 years or more
Battery pack, the battery of the above phenomenon substantially belongs to scrap from the point of view of current Maintenance Cases
To even ten tens of thousands of yuan of tens of thousands of members, how thousands of battery cores handle, how to repair, mesh the minimum several hundred members of one group of battery
Before can only be repaired by more renewing battery, for industry personage, new used batteries mismatch internal resistance is inconsistent, capacity not yet
One, basic to play less than best, how generated pressure difference can be completed by pressure balance, balance at all if pressure difference is big
Not, it is completed when and balancing by electric discharge, causes energy waste, and effect is bad.
Fixed completely to battery, unique approach is exactly to recombinate battery, recombination as new battery partial volume, survey internal resistance,
Pairing can thoroughly solve all the problems above, and old and useless battery partial volume, pairing, survey internal resistance know about industry personage, grasp
It is too difficult to make to get up, and can only produce battery producer with regard to current equipment and complete.
Therefore, it is necessary to provide a kind of more battery core internal resistance pairing aging comprehensive detector solution above-mentioned technical problems, single-unit
Battery production manufacturer all controls in 1-5 milliohm range, and the few battery pack of battery core is out of question, but 50 battery cores in whole group battery core
It is just different, such battery pack internal resistance difference is with regard to big, and the problem after sale in later period will be relatively more, due to internal resistance and voltage
Capacitor has relationship change, can take same resistance value changeable internal damp bvattery be it is impossible, producer cannot also do, thus producer most but
Battery has given large enterprises, and interior group of big flows to market, so just there is later period many problems after sale.
Why battery can explode, since the energy-intensive that ternary reason battery composition determines is big, when temperature overruns
It will explode, disorderly fly as bullet, and catch fire at once, risk is higher, so battery management system is extremely important, control
No more than range, battery is performed to it is best, then why battery pack to will appear certain group voltage high, explode, it is really fierce
Hand is exactly just to be controlled not when power-supply management system is problematic after because certain single group internal resistance of cell is with caused by battery pack is higher one by one
, it will explode, be exactly certainly charger there are also one of defence line, can also stop charging when charger reaches total voltage, but from
From the point of view of case is fallen, battery in this way not in time repair , Cuttings obtain the time it is longer cause explosion a possibility that it is higher, ternary lithium battery capacity is low
It is also possible to adhere to using, the mileage only run is few, and speed is slow, thus can also charge after using, but
It is that inside battery problem user can not learn at all, there have been hidden close, both certain 1-3 group or so the internal resistances of safety in the inside in fact
Higher voltage is higher, once when protection board controls failure, that is, explosion and fire, however ferric phosphate lithium cell is with regard to different
Sample, once the internal resistance of cell is high, voltage height etc. can stand and both decline, to can not charge or use, disadvantage advantage is all for he,
At least hard acid iron lithium, which does not explode, surpasses the low power-off of unexpected voltage, as long as circut breaking would not occur electricity is sufficient, so
To be recommended to use ferric phosphate lithium cell more, besides the service life is also 4-5 times of ternary lithium battery, so ferric phosphate lithium cell is only safety
Battery is worthy to be popularized.
The previous internal resistance instrument generally the least expensive 200 or so of mesh, but a battery core can only be surveyed, it is unable to complete tens, up to a hundred
Battery tests internal resistance simultaneously, however the link of most critical is exactly total internal resistance, but solves currently without equipment.
