Lithium battery packs are generally composed of one or several lithium-ion battery packs in series, and each lithium battery pack is composed of three to four batteries in series. The composition of working voltage, switching power supply and medical equipment can take into account the regulations for industrial processing applications. The lithium battery group bMS balanced intelligent management system can reasonably carry out testing, maintenance, energy balance and common fault alarms for the lithium battery group, thereby improving the working efficiency and service life of all driving force lithium-ion battery packs.
The lithium battery balance technology can solve the problem of SOC and C/E mismatch, thereby improving the characteristics of the series connected lithium battery group. The problem of correcting the mismatch of rechargeable batteries can be solved according to the balance of the rechargeable cells in the whole process of the original adjustment, and then it has to be balanced in the whole process of battery charging, while the CE mismatch must be balanced in the whole process of battery charging. Although the failure rate of lithium battery processors is likely to be extremely low, further quality assurance must be provided to guard against the problem of excessively 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, resulting in common failures, fire accidents, explosions, etc., which will destroy all lithium battery functional groups and cause invalidation.
At this stage, the common technical key of lithium battery balance includes passive balance, battery charging balance and active migration balance. From the perspective of development and design difficulty, cost, high balance efficiency and output power usage, microwave sensor balance is the most 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, and the output power usage rate is zero;
The amount of balance current reaches the ampere level, with high balance efficiency and high energy utilization rate;
The migration positive balance has higher complexity and higher cost, the larger the balance current is above the ampere, the balance is high efficiency and the output power utilization rate is maximized.
