Talk about the daily maintenance of lithium batteries

Lithium battery maintenance All lithium batteries have a self-maintenance circuit. A simple maintenance circuit requires at least the following elements: Protection IC: It has two-way charging and discharging maintenance, in the overcharge or overdischarge disconnection circuit to ensure safety. Fuse: Fusing the current is the last resort in an emergency. Conclusion The use of lithium batteries at low temperatures is not good in terms of charging and discharging performance, and may affect the service life of the battery, which should be prevented. The following are some popular theories about the use of lithium batteries: The first time you use it, you should fill it up three times to activate the lithium battery. In the event of a failure, the lithium battery has no recall effect and should not be activated. It is best to charge after dark. In the event of a failure, the cycle life is not a normal charging time, but an overall cycle process. Recharge the battery after it runs out, instead of plugging it in the charger and unplugging it again. Can be used as required. If the light is used to recharge, it will be too long or it will cause too much discharge, which will affect the battery life. Don't always charge, flush, and then unplug. It's a bit right, but wrong. Generally, mobile phone charging is not a simple regulated charging, but to extend battery life, there are optimized charging algorithms, including CC, CV and MC. Due to the lack of charging management equipment for some counterfeit and low-cost devices, good charging is advocated. Charge your idle mobile phone in time. correct. When the lithium battery is not placed, the power will disappear quietly, and it will be placed after it is lower than 2.0V, which will seriously affect the battery life. It is best to charge regularly. The other last but not least is how to understand how Apple slows down the door? How much?) The last question: Why does Apple raise this question, but other mobile phone manufacturers do not? Age without batteries? Here are some of my thoughts (almost no answers, the answers are in our minds). The first one is reality: as the number of cycles increases, the peak open circuit voltage that the lithium battery can supply drops slowly, that is, the voltage drops after full load. The peak current that can be supplied also drops. When the peak current drops to a certain level, the power required for the peak power consumption of the mobile phone cannot be supplied. Low temperatures can cause more serious problems. Including initial voltage drop, steep discharge curve, etc. So this is a common problem in this industry. So, why is Apple the only company that is forced to slow down? I think the iPhone is relatively stable and it is difficult to crash; the user base is very large, and every generation of mobile phones is in use. My wife also has an iPhone4. Can be used to play games; Apple must support the long tail theory. For example, Samsung already has a flash door (in fact, many Android phones have similar problems, so I won't mention it). After a year, mobile phones often crash, no one knows why it crashes (as far as I know, a certain phone also has battery aging problems, but I choose to ignore them). In fact, there are many interesting problems and algorithms for battery charging, such as CC, CV, MC, etc., as well as the latest fast charging standards. I'm not sure if we all like it, if you like it, please leave a message in the comment area, thank you!
