Method and System for Rapid Charging of Rechargeable Cells

摘要

A method (300) and system (600) of adjusting a charging current to one or more cells (601) is provided. The method includes obtaining (301) a plurality of charging time periods, where each charging time period defined as a time period required to charge the one or more cells with a predefined current at one of a plurality of different temperatures. A temperature of the one or more cells is determined (302). A predetermined current is scaled (306) by a quotient of a first charging time period defined by a first one of the plurality of different temperatures divided by a second charging time period defined by a second one of the plurality of different temperatures to obtain a magnitude of the charging current. The cells are charged (307) with the charging current at the magnitude to more rapidly charge the one or more cells at temperatures above room temperature.

1. A method of adjusting a charging current to one or more cells, comprising:
obtaining a plurality of charging time periods, each charging time period defined as a time period required to charge the one or more cells with a predefined current at one of a plurality of different temperatures; determining, with a temperature sensor, a temperature of the one or more cells; scaling, with one or more processors, the predefined current by a quotient of a first charging time period defined by a first one of the plurality of different temperatures divided by a second charging time period defined by a second one of the plurality of different temperatures, the second one of the plurality of different temperatures closer to the temperature than the first one of the plurality of different temperatures, to obtain a magnitude of the charging current; and causing, with the one or more processors, a current regulator to charge the one or more cells with the charging current at the magnitude.
