What is the basis for the correct charging of lithium-ion battery packs?

Regarding the question of how to charge the lithium-ion battery pack, we know that the lithium-ion battery pack needs to be charged with a matching charger. The domestic production supporting market. Since each product is also packaged separately and is not compatible with each other, it should be selected according to the lithium-ion battery pack used. The corresponding charger is charged strictly according to the requirements. Regardless of whether it is the home product or the civilian market, since the basic principles of how lithium-ion batteries are charged are the same, the pace and scale of charging lithium-ion batteries can be typed. Under normal circumstances, the nominal voltage of lithium-ion batteries is 3.7V. , The charging voltage is 4.2V. Beware of charging at excessively high temperatures. If you use a lithium iron phosphate battery pack at a temperature higher than the specified operating temperature, that is, 35C or higher, the battery's power will be eliminated continuously, that is, the battery's power supply time will not be as usual. That's long. If you have to charge the device at such a temperature, the damage to the battery will be even greater. Even if the battery is stored in a relatively hot condition, the quality of the battery will be damaged unpreparedly. Therefore, just keeping at a suitable operating temperature is a good way to delay the life of the lithium battery. Beware of charging at too low temperature. If you use lithium batteries in low temperature conditions, that is, below 4C, the use time of lithium ion battery packs will also be eliminated. The original lithium batteries of some mobile phones cannot even be charged in low temperature conditions. But don't worry too much, this is only a temporary situation, which is different from the use under high temperature conditions. Once the temperature rises, the molecules in the battery will be heated, and it will immediately restore to the previous power.
