US Patent 11498446 Plug-in charge current management for battery model-based online learning

A vehicle includes a battery that is rechargeable using an external power source coupled to the vehicle. The vehicle includes a controller that is programmed to estimate parameters of the battery using a parameter estimation algorithm. The controller is programmed to change a charging current when connected to the external power source to provide an input to the parameter estimation algorithm that is sufficiently dynamic such that the parameter estimation algorithm converges to an accurate solution.
