cr2032 button battery manufacturer explains the balanced charging method of series lithium batteries
cr2032 button battery manufacturer explains the balanced charging method of series lithium batteries. When cr2032 button battery packs are balanced and charged in series, the impact of the difference in capacity of single cells is ignored. Generally, the battery with smaller internal resistance is fully charged first. The design of the protection circuit can meet the protection needs of series-connected cr2032 button battery packs. It has complete protection functions and can reliably protect overcharge and over-discharge, while achieving a balanced charging function.
cr2032 button battery manufacturer explains the balanced charging method of series lithium batteries
Series lithium batteries are a common phenomenon during the battery PACK assembly process.
1. The number of PWM required for series-connected lithium batteries is 2×(n-1), where n is the number of batteries. There are relatively many. And energy transfer can only be transferred from one battery to its adjacent battery. If the number of batteries is large, the control algorithm is still quite complex, so the key issue is just cost.
2. If you use bq78PL114+BQ76PL102 for series-connected lithium batteries, you can manage up to 8 batteries. If an electric vehicle requires 80 cells, then 10 such battery packs need to be managed separately. In this case, the cost increases again. Therefore, this IC should be more suitable for handheld device cr2032 button battery packs, 12.8V cr2032 button battery packs, notebook batteries, or electric bicycle batteries.
3. For series-connected lithium batteries, the selection of PWM frequency, duty cycle, and inductor capacity are interrelated. The recommended frequency of Ti's IC is 200kHz, which can reduce the inductance and thereby reduce costs.
cr2032 button battery series connection knowledge As the battery is produced, it goes through many processes from coating to finished product. Even after strict testing procedures to make the voltage, resistance, and capacity of each power supply consistent, differences in one way or another will occur after being used for a period of time.
Just like twins born to a mother, they may look exactly the same when they are born, and it is difficult for the mother to tell them apart. However, as the two children continue to grow, there will be differences in one way or another. The same is true for lithium-powered batteries. After using for a period of time, the overall voltage control method is difficult to apply to lithium power batteries.
When charging a group of lithium batteries in series, each battery should be charged evenly, otherwise the performance and life of the entire battery group will be affected during use. Commonly used balancing charging technologies include constant shunt resistor balancing charging, on-off shunt resistor balancing charging, average battery voltage balancing charging, switched capacitor balancing charging, buck converter balancing charging, inductor balancing charging, etc.
