18650 lithium battery 2600mah

　　Why must 18650 lithium battery 2600mah be balanced?

　　Lithium battery group is the product of lithium batteries connected in series or parallel to meet certain requirements, which is very common in our daily life. The so-called balance is to maintain the entire lithium battery pack within normal range to ensure overall safety. Why must 18650 lithium battery 2600mah be balanced?

　　18650 lithium battery 2600mah are generally composed of one or several 18650 lithium battery 2600mah connected in series, and each lithium battery pack is composed of three to four batteries connected in series. The composition of working voltage, power supply and medical equipment can meet the requirements of industrial application. The lithium battery group BMS balance intelligent management system can effectively detect, maintain, energy balance and fault alarms for the lithium battery group, thereby improving the performance and service life of the entire power lithium battery pack.

　　Lithium battery balancing technology can solve the problem of SOC and C/E mismatch, thereby improving the performance of series-connected lithium battery groups. Correcting the battery mismatch problem can be solved by balancing the battery during the original adjustment process, which then only needs to be balanced during the battery charging process, while the CE mismatch must be balanced during the battery charging process. Although the failure rate of lithium battery manufacturers is likely to be very low, further quality assurance is still needed to avoid the problem of too short battery cycles.

　　The use of 18650 lithium battery 2600mah is beneficial to the safety of lithium batteries. Otherwise, if some individual lithium batteries are abnormal or cannot be operated in time, causing malfunctions, fires, explosions, etc., all lithium battery functional groups will be destroyed and cause failure.

　　At present, common lithium battery group balancing technology mainly includes passive balancing of energy consumption, charging balancing and active migration balancing. From the perspective of development difficulty, cost, balanced efficiency and power utilization, microwave sensor balancing is the most suitable. It is very easy to develop and design, with the lowest cost, the balance current is not large, generally within 100mA, the balance is high but the efficiency is low, and the power usage is zero;

　　The balance current reaches the ampere level, the balance is high efficiency, and the energy utilization rate is high;

　　Migrating positive balancing has higher complexity and higher cost, the maximum balancing current reaches more than ampere, and the balancing efficiency and power utilization are maximized.
