AI Customer ServiceAbstractŠCharge equalization is an important part of the charge process for series-connected battery cells. This paper reviews battery behavior and performance related to the equalization problem, in the context of vavle-regulated lead-acid batteries.
Figure 2 illustrates the impact of using an active equalization system for a pack of batteries. Indeed, with an active equalization system, a pack of batteries accomplishes at least 450 charging/discharging cycles, where the pack of batteries without active equalization reaches only 140 driving cycles.
In , active equalizers were tested with conventional flooded lead-acid batteries. Active equalization maintained cell-to-cell matching of better than 10 mV throughout an intensive one-week accelerated test Πeven though a low float limit of 2.30 V/cell was used.
For this reason, an equalization system is necessary, mainly for both VRLA and lithium-ion batteries [1-4]. In any battery charging process, a solution to ensure a voltage balance or equalization of the charge is needed to restore balance or at least prevent it from developing .
It shows that the performance of active systems is significantly better than passive systems. Experimental results show that even for maintenance free batteries, a periodic equalization process is needed in order to extend their lifespan. 1876-6102 © 2016 The Authors. Published by Elsevier Ltd.
In most conventional battery charging practice, equalization is addressed either by driving the charge to a sufficient potential to assure some degree of overcharge for all cells, or with a separate higher-voltage charging step intended to reach the weakest cells.
