Title:
バッテリーパック電流測定部の異常診断方法及び装置
Document Type and Number:
Japanese Patent JP5373120
Kind Code:
B2
Abstract:
Disclosed are a method and an apparatus for detecting abnormality of a current sensor operative to measure a charge or discharge current of a battery pack. The method comprises measuring current and voltage of the battery pack; and detecting abnormality of the current sensor by comparing variations in current and voltage over a predetermined time with a current reference value and a voltage reference value, respectively. According to the present invention, it is capable of improving reliability of the battery pack, and in case that the current sensor is out of order, of protecting the battery pack from dangerous accidents such as explosion.
