“…Multiple authors have proposed classification of given methods based on operation principles, charge exchange directions, used components [1]- [5]. A variety of technologies rely on safe operation of batteries [6] [7][8] [9], for example, [10] proposes a modular concept of battery charger for personal mobility vehicles for its safe operation and, in the same time, providing its expandability, but [9] reveals peculiarities if this charger. Despite the vast amount of developed methods both simulations and experimental validation shows that there is no clear winner method which would prevail in all fields: cost, simplicity, size, reliability, efficiency or efficacy, easy implementation and modularity.…”

Passive balancing is a traditional choice for lithium-ion battery packs although it is regarded as highly inefficient. One opportunity to improve traditional balancing in sub-medium size battery packs is to combine two balancing methods: passive and active. Statistical analysis have been performed to rationalize battery pack division in smaller packs and use of higher level selective charging method to decrease losses of passive balancing. An experimental balancing prototype have been designed and tested for efficiency. Results indicate energy performance degradation if cells of the pack are with low capacity variation. Proposed balancing approach could improve performance under high cell mismatch conditions.

“…The integration interval is from the beginning of balancing operation to the end when last cell reaches its full voltage. As the Ploss(t) is a discreet function then Eloss can be expressed as a sum of individual Ploss levels (6).…”
