Can CR1632 battery be charged quickly? Will fast charging be harmful to CR1632 battery?

　　Can CR1632 battery be charged quickly? Will fast charging harm CR1632 battery? Whether fast charging harms CR1632 battery depends on the battery. It is difficult to generalize. Does fast charging harm CR1632 battery? This depends on the battery density, battery material, charging temperature, and the capabilities of the battery pack management system. You don’t have to be too cautious. Concerning whether fast charging will damage CR1632 battery.

　　Fast-charging CR1632 battery refer to batteries that are charged in a short time. Generally, the battery is fully charged within 6 minutes, and the battery capacity reaches more than 95% of the rated capacity. Lithium battery fast charging is a relatively general concept. Currently, there are actually two real fast charging technologies: one is flash charging technology, and the other is Qualcomm's QuickCharge2.0 technology. It has three different implementation forms:

　　(1) Keep the voltage unchanged and increase the current;

　　(2) The current remains unchanged and the voltage is increased;

　　(3) Both voltage and current increase.

　　Can CR1632 battery be charged quickly?

　　Whether CR1632 battery can be charged quickly depends on the experimental data of lithium battery manufacturers. Not all CR1632 battery can be charged quickly. Otherwise, the life of the lithium battery will be greatly reduced, and there will be dangers such as fire and explosion. Therefore, each manufacturer will configure slow charging ports and fast charging ports according to the characteristics of CR1632 battery, and the BMS system will uniformly manage the charging process. As long as charging is carried out in accordance with the manufacturer's requirements, it is safe.

　　Some people say that charging CR1632 battery is like pouring beer. It is fast and the beer is filled quickly, but there is a lot of foam. The pouring is slow and slow, but there is a lot of beer and it is very solid. While fast charging saves charging time, it also causes greater damage to the battery itself.

　　Take lithium iron phosphate batteries and ternary CR1632 battery as examples. The advantage of lithium iron phosphate batteries is that they are resistant to high temperatures, so the temperature increase caused by fast charging has almost no impact on them.

　　Will fast charging harm CR1632 battery?

　　The essence of rapid charging and discharging of CR1632 battery is that lithium ions can quickly deintercalate between the positive and negative electrode materials. Battery material properties, process design, and charging and discharging systems will all affect high-current charging performance. Fast charging will input a large current into the battery in an instant. Frequent use of fast charging mode will reduce the battery's recovery ability and reduce the number of battery charge and discharge cycles.

　　Practical theory proves that fast charging is the most destructive to CR1632 battery. The working principle of fast charging is: first increase the voltage, and second, increase the current current. Just like this, fast charging also uses this principle, so a large amount of current will cause the battery plate to react at an excessive speed. This reaction can generate a large amount of heat due to internal resistance and exceed the limiting temperature value, thereby damaging or prematurely aging the lithium battery.

　　Fast charging only increases the input current within the allowable range. From this point of view, there should be no damage. However, the lithium battery generates more heat than slow charging. Serious battery heating may accelerate aging. From the editor's practical experience, slow charging The usage time is longer than quick charging.

　　Slow charging is plugged into a 220V AC socket at home for charging. Since the battery cannot accept AC charging, slow charging converts 220V AC into DC and then boosts it to the battery charging voltage such as 500V DC. Then use this 500V DC charges the battery. Simply put, fast charging has very high requirements for the quality of CR1632 battery, and the reaction conditions of batteries under high current are too harsh and violent, deviating far from the equilibrium state, which will cause a great loss in the life of the battery and the safety factor will be significantly reduced. So try to do as little as possible when it is not necessary.
