Title:
バッテリの制御装置、バッテリの制御方法、及び、バッテリ
Document Type and Number:
Japanese Patent JP4816705
Kind Code:
B2
Abstract:
A battery controller includes: a temperature detecting section including at least one temperature detecting element whose resistance changes with changes in the temperature of a battery cell and/or a charge/discharge control switch connecting the cell with an external apparatus; first and second voltage divider circuits respectively including first and second resistive elements connected with the temperature detecting element; and a control section applying a reference voltage to the first or second voltage divider circuit while switching it such that the value of a voltage applied to the temperature detecting element according to a voltage dividing ratio between the resistive element and the voltage divider circuit changes proportionally to the temperature of the cell and/or the switch, and controlling the switch such that the external apparatus is connected to the cell when the temperature of the cell and/or the switch detected based on a voltage division output of the voltage divider circuit is between first and second temperatures.
