Advances in EKF SOC Estimation for LiPB HEV Battery Packs
This paper describes advances in models and methods used to estimate hybrid-electric-vehicle (HEV) battery-pack state-of-charge (SOC) using extended Kalman filtering (EKF). The electrochemical cells in the battery pack are Lithium Ion Polymer based, have a nominal capacity of about 7.5 Ah, and are optimized for power-needy applications. The discharge curve of these cells is very flat, which is ...
متن کاملExtended Kalman filtering for battery management systems of LiPB-based HEV battery packs Part 1. Background
Battery management systems (BMS) in hybrid-electric-vehicle (HEV) battery packs must estimate values descriptive of the pack’s present operating condition. These include: battery state of charge, power fade, capacity fade, and instantaneous available power. The estimation mechanism must adapt to changing cell characteristics as cells age and therefore provide accurate estimates over the lifetim...
متن کاملStudying lithium-ion battery packs cooling system using water-nanofluids composition
In this study, the Li-ion batteries temperature increase during the discharge process was measured empirically and evaluated using numerical simulation. Moreover, the battery packs cooling using the water, air and water-nano composition fluids such as water-alumina, water-copper oxide, and water-gold was studied through numerical simulation. Accordingly, the battery cooling was simulated by CFD...
