Analysis of the inconsistency problem of Li-ion battery packs | Part 2

in News

The reasons for inconsistency in battery formation are mainly the initial differences between single cells and the differences in structure, usage conditions, and environment after battery formation. To alleviate the problems of performance degradation and life reduction brought by battery formation, we can optimize the manufacturing process of batteries to reduce the initial differences of batteries; screen the batteries before battery formation, and group the batteries with less inconsistency; fully consider the influence of connection methods and structures on inconsistency when combining battery group systems; and carry out reasonable battery management, effective equalization as well as thermal management in the process of use to Reduce the inconsistency caused by different usage conditions. Among the technologies to improve battery pack consistency, BMS and thermal management technologies are relatively mature, while SOC estimation accuracy and equalization effect need to be further improved.

5G base station applications lithium iron phosphate battery advantage "crush" lead-acid battery

in News

With the conversion of communication base stations from lead batteries to ladder lithium iron phosphate batteries, it is difficult for lead-acid storage demand to ride on the east wind of 5G. Lead battery compared with ladder lithium iron phosphate battery, there are short life, low performance, containing a large amount of heavy metal lead disadvantages. The ladder lithium battery will completely replace lead batteries in base stations, backup power, and other areas with lower requirements for battery performance.
