What is the significance of the balance management of lithium-ion battery packs

What is the significance of the balance management of lithium-ion battery packs. Lithium-ion battery packs are generally composed of one or more battery cells in series and parallel. The BMS balance intelligent management system can reasonably carry out detection, maintenance, energy balance and common fault alarms for lithium battery groups, and then Improve the working efficiency and service life of all driving force lithium-ion battery packs. Lithium battery balancing technology can handle the problem of SOC and C/E mismatch, thereby improving the characteristics of series connected lithium battery groups. The problem of correcting the mismatch of the rechargeable battery can be handled according to the balance of the rechargeable battery in the whole process of the original adjustment, and then only the balance must be carried out during the whole process of battery charging, and the CE mismatch must be balanced during the whole process of battery charging. Although the failure rate of lithium battery manufacturers is likely to be extremely low, they must still show further quality assurance to prevent the problem of too short battery cycles. The use of lithium-ion battery packs is beneficial to the safety of lithium batteries. Otherwise, some single lithium batteries are found to be abnormal or cannot be operated immediately, causing common failures, fire accidents, explosions, etc., which will destroy all lithium battery functional groups and render them invalid. At this stage, the key to common lithium battery balance technology includes passive balance of energy consumption, active balance of battery charge balance and migration. From the perspective of development and design difficulty, cost, balanced high efficiency and output power utilization rate, the microwave sensor is the most balanced. It is very easy to develop and design, the cost is the least, the balance current is not large, generally within 100mA, the balance is high and the efficiency is low, the output power utilization rate is zero; the balance current reaches the ampere level, the balance is high efficiency, and the energy utilization rate is high; Active balance has higher complexity and higher cost, and the larger balance current is above ampere, the balance is high efficiency and the output power usage rate is the largest.
