Samsung patents method to estimate battery parameters from electrode material

Patent drawing
Patent drawing from the official filing.

Samsung has been granted a patent for a method that estimates battery parameters by checking if the diffusion length of an intercalation material in an electrode is below a certain threshold. The processor then calculates the material's concentration and uses that to estimate battery details like charging or discharging states.

Why it mattersThis could help electronic devices manage their batteries more precisely by tracking internal material concentrations to control charging and detect issues like short circuits.

In the filing’s own words

Methods and an electronic devices for estimating battery parameters, where the method of estimating battery parameters performed by a processor includes determining whether a diffusion length of an intercalation material in an electrode of a battery is lesser than a threshold, calculating a concentration of the intercalation material in the electrode based on a result of the determination, and estimating at least one battery parameter of the battery parameters based on the concentration of the intercalation material.

What exactly they claim (claim 1)

1. A method of estimating battery parameters performed by a processor, the method comprising: determining whether a diffusion length of an intercalation material in an electrode of a battery is lesser than a threshold; calculating a concentration of the intercalation material in the electrode based on a result of the determination; estimating at least one battery parameter of the battery parameters based on the concentration of the intercalation material; and controlling at least one of charging of the battery, discharging of the battery, or detection of short circuits of the battery based on the estimated at least one battery parameter.
