    摘要： A method and system for managing a battery system. The method including receiving at least one measured characteristic of the battery over a pre-defined time horizon from the at least one sensor, receiving at least one estimated characteristic of the battery from a electrochemical-based battery model based on differential algebraic equations, determining a cost function of a Moving Horizon Estimation based on the at least one measured characteristic and the at least one estimated characteristic, updating the electrochemical-based battery model based on the cost function, estimating at least one state of the at least one battery cell by applying the electrochemical-based battery model, and regulating at least one of charging or discharging of the battery based on the estimation of the at least one state of the at least one battery cell.

    摘要： A battery management system comprising a processor and a memory storing instructions that, when executed by the processor, cause the battery management system to estimate one or more states of the battery by applying a battery model to account for physical parameters of a chemical composition of the battery based on one or more measured characteristics of the battery and the one or more estimated characteristics of the battery and regulate a first charging mode of the battery based on the estimation of the one or more states of the one or more battery cells and switch between the first charging mode and a second charging mode based on the estimation of the one or more states of the battery to allow for rapid charging of the battery.

    摘要： A method for charging a battery comprises: measuring a battery voltage with a voltage sensor and a battery current with a current sensor; applying, with a charging circuit, a first charging current to the battery until the measured battery voltage exceeds a predetermined voltage threshold, a magnitude of the first charging current being held at a first constant value; applying, with the charging circuit, in response to the measured battery voltage exceeding the predetermined voltage threshold, a second charging current to the battery until a cutoff criterion is satisfied, a magnitude of the second charging current being such that the battery voltage exceeds a steady state voltage limit for the battery; after the cutoff criterion is satisfied, determining a rest voltage of the battery; and updating the cutoff criterion based on a difference between the determined rest voltage and a target rest voltage.
