Apparatus & Method for Estimating the State of Health of a Battery via updating the OCV and SOC relationship
The problem: Within a few months from purchase, the fuel gauge in battery-powered devices, from cell phones to EVs, starts to become inaccurate. This is usually noticeable towards the end of discharge where the battery level may suddenly drop from 30% to 5%. This is not a battery problem but a monitoring problem and while this is an annoyance for c...
