18650 battery 3.7v 6000mah protection circuit design, 18650 battery 3.7v 6000mah protection board principle
18650 battery 3.7v 6000mah protection circuit design, 18650 battery 3.7v 6000mah protection board principle. During the charging process of lithium batteries, each 18650 battery 3.7v 6000mah is equipped with a balancing circuit. During charging, the voltage of each battery is controlled through the balancing circuit of the 18650 battery 3.7v 6000mah protection board, so that each string of batteries remains in the same state, ensuring the safety of the 18650 battery 3.7v 6000mah. Performance and longevity. The protection circuit of lithium-ion batteries ensures safety in such overcharge and discharge states and prevents deterioration of characteristics.
Things to note when designing 18650 battery 3.7v 6000mah protection circuits
●Overcharge and overdischarge of lithium batteries will affect the life of the battery.
●Pay attention to the charging voltage and charging current of the 18650 battery 3.7v 6000mah. Then choose the appropriate charging chip.
●Be careful to prevent overcharging, over-discharging, short-circuit protection and other problems of lithium batteries.
●The 18650 battery 3.7v 6000mah protection circuit must undergo a large number of tests after being designed.
When we design products that require the use of lithium batteries, we need to design a protection circuit for the 18650 battery 3.7v 6000mah. Only on this basis can we design the charging circuit. Lithium batteries require overvoltage charging protection, overvoltage discharge protection, overcurrent discharge protection, short circuit protection, etc. Therefore, when we design a 18650 battery 3.7v 6000mah protection circuit, we must at least achieve the above protection functions.
The 18650 battery 3.7v 6000mah protection board also has the function of protecting the battery and preventing the battery from overcharging. When the external power supply continues to charge the battery rapidly, the 18650 battery 3.7v 6000mah protection board will have a protective effect. When the internal power of the 18650 battery 3.7v 6000mah reaches saturation, the internal circuit of the 18650 battery 3.7v 6000mah protection board will automatically cut off the external fast charging power supply. This prevents external power from entering the battery. This is also the principle of the 18650 battery 3.7v 6000mah protection board to protect the battery from overcharging. The ultra-small package and few external device requirements of 18650 battery 3.7v 6000mah protection IC make it widely used in the design of single-cell 18650 battery 3.7v 6000mah protection circuits.
18650 battery 3.7v 6000mah protection board principle
The reason why 18650 battery 3.7v 6000mah (rechargeable type) needs protection is determined by its own characteristics. Since the material of the 18650 battery 3.7v 6000mah itself determines that it cannot be overcharged, overdischarged, overcurrent, short-circuited, or charged and discharged at ultra-high temperatures, the 18650 battery 3.7v 6000mah components will always appear with a delicate protective board and a current fuse.
The protection function of lithium batteries is usually completed by a protection circuit board and current devices such as PTC. The protection board is composed of electronic circuits and can accurately monitor the voltage and charge return circuit of the battery core at all times in an environment of -40°C to +85°C. Current, timely control the on and off of the current loop; PTC prevents severe damage to the battery in high temperature environments.
The 18650 battery 3.7v 6000mah protection board is mainly composed of a protection IC and a MOS tube. It is a device used to protect the safety of 18650 battery 3.7v 6000mah cells. Lithium batteries are widely used due to their large discharge current, low internal resistance, long life, and no memory effect. Lithium-ion batteries are prohibited from overcharging, over-discharging, and short circuiting during use, otherwise they may cause fatal defects such as fire or explosion. , Therefore, when using rechargeable lithium batteries, there will be a protective board to protect the safety of the battery cells.
