Diffusion-limited adaptive battery charging

摘要

A method for adaptively charging a battery, comprising: applying a charging current to the battery; entering a zero current state in which the charging current is set to zero; during the zero current state, measuring an open circuit voltage for the battery at two times while the open circuit voltage relaxes toward a steady state; calculating an updated charging current or charging voltage for the battery based on the measured open circuit voltages; and applying the updated charging current or charging voltage to the battery.
