The technical challenges and difficulties of the lithium-ion battery management are primarily in three aspects. Firstly, the electro-thermal behavior of lithium-ion batteries is complex, and the behavior of the system is highly non-linear, which makes it difficult to model the system.
Differential charging of cells with age has turned balancing management systems into an important research subject. This paper proposes a new battery management system (BMS) to improve the capacity usage and lifespan of large Li-ion battery packs and a new charging algorithm based on the traditional multistage method.
The battery management system is key to the safe operation of the battery system and is often equipped to track operating conditions and monitor the battery system for potential faults . Without real-time, effective fault diagnosis and prognosis methods, a small failure can lead to even serious damage to the battery system .
To ensure safety and prolong the service life of Li-ion battery packs, a battery management system (BMS) plays a vital role. In this study, a combined state of charge (SOC) estimation method and passive equi- librium control are mainly studied for lithium cobalt oxide batteries.
Decentralized BMS provides management circuitry to each cell or number of cells to give gain more control over the battery system in terms of efficient energy management, fault handling, and special balancing techniques . As each type of system has several advantages, it also comes up with many disadvantages . ... ...
