Lithium battery repair methods, lithium battery repair technology encyclopedia
Lithium battery repair methods, lithium battery repair technology encyclopedia. Generally speaking, lithium batteries have a life span of 300 to 500 charging cycles. After a certain number of uses, the capacity will be significantly reduced and repairs will be required. Lithium batteries are now widely used. How can we save costs and resurrect "dead" lithium batteries? Let me share my experience with you.
Everyone may have doubts about the technology of repairing and repairing lithium batteries, because everyone thinks that the performance of lithium batteries has weakened, the range has decreased, the battery cannot be charged, etc. As long as problems arise, the battery can no longer be used. To be replaced. Today, the editor tells you that this idea is completely wrong, because not only can the lithium battery of electric vehicles be repaired, but its performance after repair can be restored to more than 90%.
①Repair method of lithium battery of electric vehicle
1. Many electric vehicle lithium batteries seem to be no longer usable. In fact, we do not really understand them. First of all, we must use Shineng and lithium battery balance repair instruments to detect the battery voltage, discharge and voltage difference to identify which part or Which battery is damaged and causes the entire battery pack to malfunction.
2. After detecting the root cause of the fault, use a balance repair instrument for technical treatment. Generally, for lithium batteries, the problem is mostly due to damage to the lithium battery protection plate or damage to the lithium battery cell. If the protection plate is damaged, , you only need to replace the protective board. If the battery core function is damaged, you need to use Shineng and lithium battery balance repair instrument to repair the lithium battery voltage difference so that each string of the battery pack can be fully charged. At the same time, Discharging can also maximize the use of stored power.
3. The common balancing charge on the market is to directly charge the voltage difference of each string of the battery pack to 4.2v, which is a high-voltage repair. After a discharge cycle based on this repair principle, the battery pack voltage difference will still exist, and it needs to be charged every time. After discharging, it must be repaired again.
②How to repair mobile phone lithium battery
1. Use a clean eraser or other cleaning tools to gently wipe the metal contacts on the lithium battery and the metal contacts on the mobile phone, which will help the charging status and the durability of the power.
2. Wrap the old mobile phone lithium battery that automatically shuts down with plastic wrap firmly, and try to wrap it as snugly as possible, with a total of three layers inside and outside to ensure that the battery is in a vacuum state. Then, wrap three layers of newspaper outside the plastic wrap to completely seal the lithium battery. Place it in the freezer layer of the refrigerator. After 48 hours, take out the battery and remove the six layers of paper wrapping one by one. The lithium battery has no surface expansion or deformation due to freezing. After cooling for a period of time, then charge.
3. Completely discharge the nearly scrapped lithium battery, and then recharge it to activate the battery. The specific method is: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal power, which requires some unconventional methods. A special device is used to connect the mobile phone to a small low-voltage light bulb, and the power inside the battery is transferred to the small light bulb until all the light is emitted.
I believe that through the above introduction, we can repair the battery to a certain extent. In addition, we should also pay attention to the use of mobile phone lithium batteries in our daily lives. Only by developing good habits can we make the battery life of our mobile phones longer. long.
③How to repair 18650 lithium battery
1. Take out your 18650 lithium battery after all use, and use temperature treatment. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no electricity and a considerable part of the lithium ions already have memory cells. In this way, part of the memory power can be released. When winter comes, put it outside for a while and then put it inside the house.
2. There is another way to remove the battery and leave it for about a week to slowly consume the power. You need to use a machine to completely consume the power first. Then charge it fully. I guess your current charging time must be very short. After charging it completely, disconnect it and charge it again. Repeat it several times. It will definitely be effective.
④Lithium battery pack repair method
◆Discharge
The lithium battery pack can be discharged by turning on the battery or connected to a resistor. The power-on discharge should be at the level where the mobile phone stops immediately when it is turned on; the discharge after connecting a resistor can be done by connecting a small electric bead of corresponding voltage to discharge for a long time until the small electric bead is extinguished instantly after being connected. The discharge current is preferably large.
◆Activate
12V AC power is connected in series, and a small bead or resistor is connected in series between the lithium battery packs for current limiting. First, use a small current to activate, so that the control loop AC current is tens of milliamperes, maintain it for 30 to 60 minutes, and then increase the current to 1 to 2 times the nominal value of the battery.
◆Replace batteries
A lithium battery pack that is about to reach the end of its life is actually because its internal lithium cells are close to their life limit, so as long as we replace the internal lithium cells, the lithium battery pack can be given a new lease of life.
