Abstract

Official abstract text for this publication.

A battery is charged by first charging the battery at a constant current during a first time interval, and then charging the battery at a varying current during a second time interval. The battery can be a lithium-ion battery, and the charging uses a kinetic model. The kinetic model models the battery having an indiffused well having a capacity c, and a diffused well having a capacity 1−c, and the indiffused well is filled directly by the current, and the diffused well is filled only from the indiffused well via a valve with constant inductance.

First claim

Opening claim text (preview).

We claim: 1. A method system for charging a battery, comprising: charging the battery at a constant: current during a first time interval; and charging the battery at a varying current during a second time interval, wherein the charging uses a kinetic model, wherein the kinetic model models the battery as having an indiffused well and a diffused well, and wherein a charging current to the indiffused well is regulated to exactly compensate for a current flow from the indiffused w…
