Many friends have encountered the situation of the battery drum when playing the drone, in general, we may directly replace the battery, and actually drum-capped drone lithium-ion batteries can also save. Why does the unmanned polymer lithium ion battery drums? How do we repair a lithium-ion battery for drum bag? Airplane drone high-magnification polymer battery Why drum 1) Process problem Lithium-ion battery in the upstream cell factory quality problem, or liquid level is not standard, positive and negative material material is not closed, motor coating The problem of material related to material such as uneven or shell deformation, and the phenomenon of failure of dust caused by dust or assembly. 2) If the storage or operation is improperly charged, or excessive discharge can cause gas pressure in the battery to cause drum bag, basically, the drum bag of the aeriality lithium ion battery is because of the pre-release.
Due to the unfamiliarity of battery performance, it will continue to fly at a low power. This can not only cause damage to the lithium-ion battery, but also have a large crash risk. In addition, the packet caused by charging is also a lot.
When charging is set, excessive charging current can also cause drum pack of lithium-ion batteries. Or use the battery equilibrium charger with unqualified quality. Finally, some battery drums are due to improper storage.
The high-magnification of the aerial model is not filled with electric storage. When it is placed in the dry and cool place, it is the correct place to store the amount of electricity from 30% to 50%. When it is fully charged, the battery will be drums in 15 days.
3) The environment or the use temperature affects the temperature of the charge and discharge performance of the battery, if the temperature is lowered, the reaction rate of the electrode also decreases, assuming that the battery voltage is kept constant, the discharge current is lowered, the power output of the battery will also decrease. The ambient temperature range should be between 5 and 30, and general charging efficiency increases with temperature, but when the temperature rises to 45, it will damage the chemical balance in the battery, resulting in side reactions, high temperature charging lithium-ion batteries The performance of the material will degrade, speed up the risk of the battery, and the lithium-ion battery will also be greatly shortened. Is it possible to use a navigator drone polymer lithium ion battery? Tell some other points of view when using it, then now I will publish a pertinent saying, can be used, but security, and battery performance will decline.
However, once a piece of battery in a set of batteries occurs, the routine balance charger may not be competent to charge it. At this time, it is best to have a lithium-ion battery equilibrium charger that can actively balanced. Why? Because when the polymer lithium ion battery appears in the phenomenon.
The cell has been damaged. The lithium-ion battery after injury will have a significant decrease in capacity, which also leads to an unevenly equalization of the entire battery pack. The conventional passive equalization charger is unable to have a battery with excessive capacity deviation.
Performing balance charging. Why is the unbalanced model lithium ion battery to use the normal battery in the normal battery? Big part: a battery pack of normal state, a battery capacity of 1000mAh, B battery capacity 1000mAh, this battery is in charge and discharge, their remaining capacity is almost almost, basically achieving simultaneous, and simultaneous Low power alarm, a single-chip battery is unbalanced battery pack: unpolished A battery capacity of 1000mAh, the bulk B battery capacity may only be 800mAh, low capacity low battery cells Faster full of overcharge. Circulating several times, there will be relatively large differences in the two batches, and the balance will relieve this process, but there will be differences.
Only active balanced chargers can be filled with two batches at the same time. In addition, when used, the difference between the different capacities of the two-piece battery is different, so return to the replacement battery earlier, and cannot complete the aircraft low-power alarm again, because a piece of battery is already in an empty state, instantaneous Pressure degradation can cause the drone to stop in the air. This is especially paying attention to.
Can the drone polymer lithium-ion battery drum bag repair? The answer is that there must be a certain probability that the probability of repair will be relatively large when the quality of the battery is better. Probably explain the repair step now. Be sure to ask DIY to do strong skills.
Do not attempt to prepare a multimeter, you need to measure the voltage state of the single-chip battery in advance, theoretically, there is only 0.5V voltage to complete the repair. If the voltage is 0 and there is no change, do not try to repair this battery, and this type of battery is shorted.
It is unpackable, and during the repair process, it is not trying to repair the battery. Nickel-hydrogen battery charger, the cheapest type (non-smart, without battery state detection), this charger is usually output to output a voltage and current constant flow, slowly filled with electricity. Preparing this material is important to take into account some battery drums, due to the long time, the voltage has been low, and some even only 0 points V.
This charger can be re-activated with a small current to 1.5V. Dedicated lithium-ion battery charger, (without battery condition monitoring, if you don't recognize the type of charger, you can prepare a normal lithium-ion battery.
When the lithium ion battery lower than 1V is activated, when the voltage is reached, the electrical negative electrode is connected to a lithium ion battery charger. If the lithium ion battery charger begins indicates that the charger is measured. The positive and negative online voltage has exceeded 2V.
If it exceeds it, waiting for a few minutes in place, pay attention to the heat of the battery in the charging state, it will be disconnected when heating is abnormal. If normal, wait for the charger full of instructions. Note: If the lithium ion battery charger does not recognize the low 2V lithium-ion battery, the normal lithium ion battery can be loaded to activate the charging state of the charger, and then immediately disconnect it.
Active balanced lithium-ion battery charger, when the lithium battery of the monolithic drum is suggested, the drum phenomenon will be slightly improved. After several charge and discharge, the drum phenomenon will completely disappear, and the lithium-ion battery will be repaired. Discover some changes in shape, this is normal.
Note: Lithium-ion batteries after drum bag repair must be charged using an active equalization charger. Terminate it in advance when using. .
