Abstract

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.
