• ### Sensors-models trade-offs in battery state estimation

Publication Year: 2014, Page(s):1 - 7
| | PDF (1119 KB)

In this paper, we explore the trade-offs between sensors' and models' accuracy for state estimation in battery management systems. If, in a battery pack, high quality sensors were used, then state estimation (or monitoring) would be improved at the expenses of hardware costs. On the other hand, if accurate models were used within the estimation algorithms, better estimates could be produced at the... View full abstract»
