Charging device for charging rechargeable batteries with temperature-dependent termination of the charging process

摘要

A charging device for charging a rechargeable battery including a current supplier for supplying charging current to a battery having an initial temperature at the beginning of the supply of charging current, a selector for selecting an end temperature based on a temperature range the initial temperature is in and a current terminator for terminating the supply of charging current when a battery reaches the end temperature. A rechargeable battery including a strain gauge having a temperature coefficient differing from a temperature coefficient of the battery housing is also provided.
