This paper introduces a new perspective on cell balancing (equalization) in lithium-ion battery pack by proposing the thermal concept of cells. Thermal can be achieved relative temperature control based either conventional active circuits or module-integrated systems. Compared to voltage/state-of-charge (SoC) balancing, used as target with several advantages. First, absolute directly affects lifetime and usable capacity cell. Second, between cells degrades uniformity increase imbalance...
