What is the common fault problem of lithium-ion batteries? Although the lithium-ion battery compared to the lead-acid battery, there is a lot of safety performance, but it will still have faults. The reason for the failure of lithium-ion batteries has been understood, in order to have a short-on-in-in-wocket to make a quick maintenance when there is a problem. Problems in the production of lithium ion batteries ● The positive and negative poles of the battery internal resistance battery are not welded during welding, or the internal resistance of the rivet and the pressure plate will affect the internal resistance of the lithium-ion battery.
The diaphragm is too small to affect the internal resistance of the battery. ● Battery voltage is mixed into impurities in the production of lithium-ion batteries, and the negative electrode will reduce the voltage of the lithium ion battery. In the process of chemical formation, the SEI film formation is incomplete and the lithium ion battery voltage is too low.
Problems in the process of lithium-ion batteries ◆ Cannot charge and discharge the lithium ion battery when charging is charged, it is not possible to discharge normally, there may be several reasons. The protective plate protection is not recovered or the protective board fault and the cause of the lithium-ion battery and the external shortage of the electrical appliance may result in a lithium-ion battery that cannot be effectively charged. Lithium-ion battery voltage low protective plate protection or controller protection, the same protective plate or controller is damaged to the lithium-ion battery inactive.
The same result will occur if the line is disconnected. ◆ Temperature abnormality If the lithium ion battery is charged or discharged, the temperature is abnormal, such as the temperature is too high. The reason for this happens may be that there is a slight short circuit inside the lithium ion battery.
◆ Suddenly stopping the working lithium-ion battery suddenly stops working during the use, a large possibility is that the electrical layout in the lithium ion battery is complete, and the minimum lower limit voltage of the protective plate or the controller, the self-protection function of the lithium-ion battery results in Electric power. Too much working current is more than the design of the protective plate, which will continue to operate the protective plate or controller, causing the lithium ion battery to suddenly stop working. The above is a common fault problem and some causes of lithium-ion batteries.
About the cause of the lithium ion battery can be more payable, not only when it occurs, it can be checked quickly, but also before the failure does not appear. Prevention, try not to specifically cause the error of lithium-ion battery failure. .
