Battery management systems: accurate state-of-charge indication for battery-powered applications

Battery Management Systems: Accurate State-of-Charge Indication for Battery-Powered Applications describes the field of State-of-Charge (SoC) indication for rechargeable batteries. With the emergence of battery-powered devices accurately estimating the battery SoC, and even more important the remaining time ofuse, becomes more and more important. An overview of the state-of-the-art of SoC indication methods including available market solutions from leading semiconductor companies, e.g. Texas Instruments, Microchip, Maxim, is given in the first part of this book. Furthermore, a universal SoC indication system that enables 1% or better accuracy under all realistic user conditions is developed.A possible integration with a newly developed ultra-fast recharging algorithmis also described. State-of-the-art overview of battery chemistry and changing models. General and thorough overview of the State-of-Charge methods for rechargable batteries, describes high remaining run-time indication accuracy through simple and on-line adaptive models. Covers all disciplines from electrical, chemical, mathematical and measurement engineering to understand battery behavior. INDICE: 1: Introduction. 2: State-of-the-Art of battery State-of-Charge determination. 3: A State-of-Charge indication algorithm. 4: Methods for measuring and modelling the battery's Electro-Motive Force. 5: Methods for measuring and modelling the battery's overpotential. 6: Battery aging process. 7: Measurement results obtained with new SoC algorithms using fresh batteries. 8: Universal State-of Charge indication for battery-powered applications. 9: General Conclusions.
