Battery Modeling: A Versatile Tool to Design Advanced Battery Management Systems

“…Reported simulation results are in good agreement with experiments [4,[7][8][9][10]. Figure 6 represents the electronic network model for a NiMH battery, in which the two electrodes and, in between, the electrolyte can be recognized (see Figure 3).…”

“…Because the overpotential for the recombination reaction at the MH electrode is relatively high it has been argued that its rate is most probably transport-controlled by the oxygen supply through the electrolyte [4]. The oxygen recombination mechanism ensures that the partial oxygen pressure inside the NiMH battery will be kept low.…”

“…Equivalent electronic network models have been developed for various types of rechargeable batteries [4,[7][8][9][10].…”

Physical upgrading of scrap from Ni-Cd batteries. A first step toward an integrated metal-recycling process

“…It should be noticed that, in a sealed battery, neither electrode is completely "pure". While Ni forms could reportedly be found in the anodic plate, most battery manufacturers add a significant amount of Cd(OHJ2 to the Ni electrode as a depolariser (13). The hydroxide is then likely to be reduced to metallic Cd during overdischarging, which is pretty much the case here (spent cells).…”

Improving the EGSE of power subsystem by design and development of a battery emulator for space applications

“…A variety of electric/electronic networks and several one/two-dimension electrochemical models are investigated, in order to improve the knowledge about battery modeling [2,3,4].…”
