Abstract: A battery system includes a battery that couples to an electrical system. The battery system also includes a battery control module that electrically couples to the battery. The battery control module performs a parallel current integration process on an initial state of charge using an actual capacity and a candidate capacity of the battery. Additionally, the battery control module performs a directional comparison between an estimated state of charge of the battery and results of the parallel current integration process. Further, the battery control module determines validity of the estimated state of charge based at least in part on the directional comparison between the estimated state of charge of the battery and the results of the parallel current integration process

Abstract: A battery system includes a battery that couples to an electrical system. The battery system also includes a battery control module that electrically couples to the battery. The battery control module monitors at least one monitored parameter of the battery, and the battery control module recursively calculates at least one calculated parameter of the battery based on at least an equivalent circuit model, the at least one monitored parameter, and a Kalman filter.

Abstract: A battery system may include a battery that in operation couples to an electrical system, and a battery control module that in operation electrically couples to the battery. The battery control module may read battery data, estimate a state of charge of the battery based at least in part on the battery data, and estimate a state of charge error of the battery based on magnitudes of state of charge error sources. Additionally, the battery control module may update a state of health estimation of the battery when the state of charge error of the battery exceeds a predetermined threshold.

Abstract: A battery system includes a battery that couples to an electrical system. The battery system also includes a battery control module that electrically couples to the battery. The battery control module monitors at least one monitored parameter of the battery, and the battery control module recursively calculates a first capacity estimation of the battery using two linear regression models based on at least an equivalent circuit model, the at least one monitored parameter, and a Kalman filter.
