Causes and solutions for dynamic lithium-ion battery pack heat loss. The dynamic lithium-ion battery pack generated thermal out-of control means that the battery pack has problems, it is necessary to process in time, otherwise it is likely to cause dangerous and loss to users. Since the dynamic lithium-ion battery pack is thermal out of control, it is a very dangerous thing to understand the causes of thermal out of control and the method of solving the way.
It is best to get a warning from the cause of what happens. When the lithium ion battery pack is to pay attention to prevent the occurrence of heat loss. Under the use of a dynamic lithium ion battery, the lithium-ion battery pack is affected by the use of the lithium-ion battery pack, and the relative displacement of the different parts of themselves.
The lithium ion battery pack cell is external to the external force causes the internal collision, squeezing And puncture, etc. also belong to mechanical abuse. In mechanical abuse, the most dangerous is a puncture, the conductor is inserted into the battery body, resulting in direct short circuit, compared to collision, squeezing, etc.
The probability of out-of control is higher. Electrical abuse of electrical abuse of lithium-ion battery packs, generally include foreign short circuits, overtakes, over several forms, which is most likely to develop heat-out of control. The outer short circuit, when there is two conductors that exist in the outside of the battery, the external short circuit has happened.
From external short circuit to thermal out of control, the important part of the middle is too high. When the heat in the external short circuit cannot be dispersed well, the battery temperature will rise, and the high temperature trigger heat is out of control. Overcharge, due to its energy, it is the highest harmful in electrical abuse.
The emergence of heat and gas is two common features during the charging process. Heat heat comes from ohm hot and side reactions. The abuse mechanism of over-discharge is different from other forms of abuse mechanism, and potential dangers are much higher than people think.
Copper delegthmia having a lower potential is formed by the film by the copper ions caused by over-discharge caused by the discharge. As the growth continues to increase, the copper delegated crystal may penetrate the membrane, resulting in serious thermal loss of control. Power or abuse local overheating may be a typical heat abuse of the battery pack.
Thermal abuse is rarely existed, often from mechanical abuse and electrical abuse, and is the one ring that end directly touches. The thermal out-of-control solution of thermal out-of-control is to replace this problem-free lithium-ion battery pack, abandoned, damaged batteries that have occurred on physical components. When the heat in the external short circuit cannot be dispersed well, the battery temperature will rise, and the high temperature trigger heat is out of control.
Therefore, cutting off the short circuit current or dissipating excess heat is a method of suppressing further thermal out of control of electrical abuse of the outer short circuit. Local overheating may be due to loose contact, and the heat abuse of loose problems. The solution can be checked by the battery pack, check the loose place, and then connect it well.
When the dynamic lithium-ion battery pack heat loss is serious, the best solution is to replace it, no longer use, after all, safety is more important. When this problem is discovered when the out-of control situation is not serious, the problem is eliminated as soon as possible, solve it, the lithium-ion battery pack does not have a big problem, can continue to use. .
