What is the purpose of equalizing the Li-ion battery?
Li-ion battery pack is made up of multiple cells, as the cells are independent individuals, there will be some small differences, after the combination of welding, and because of the direction and length of the connection piece, and the impact of the welding process will increase the differences, each charge and discharge will aggravate the value of individual differences, when the value reaches a certain height, will eventually lead to the local overcharge and over discharge of the cells, this situation will This situation will cause damage to the battery cell, which eventually leads to the entire group of lithium battery effectiveness can not work. Lithium-ion battery equalization can solve this problem, when the single string lithium-ion battery has a large value difference, the BMS control of the battery equalization voltage, can maximize the service life of lithium batteries.
What are the effects of an unbalanced Li-ion battery pack.
On top of some lithium-ion battery packs with less string and less parallel can not use the equalization circuit, but to ensure that the group of single cells have high quality and consistency, and charge and discharge flow is small is no problem, if the battery belongs to the larger current discharge, it is very necessary to support equalization, usually, the life of lithium battery packs without equalization are lower than lithium battery packs with equalization function.
What is the importance of balanced charging for Li-ion battery packs?
high-current lithium-ion batteries used in some models or plant protection drones, due to the high current, usually can not use the protection plate when discharging, but need to use a professional balance charger to charge it, balance charging will have a great impact on the safety and life of the battery;.
