電子機器および電子機器システム
Document Type and Number:
Japanese Patent JP5519853
Kind Code:
B1
Abstract:
PROBLEM TO BE SOLVED: To provide electronic equipment and an electronic equipment system for achieving both quick charging and safety by calculating a resistance value in a charging terminal and a battery pack, and calculating an appropriate current value suitable for the resistance value.SOLUTION: An electronic equipment system includes: electronic equipment 10 and a charger 50. The electronic equipment 10 includes: a battery pack 20; and a terminal main body part 30. The battery pack 20 includes: a casing 21; a battery cell 22; a charging terminal 27; and a data terminal 28. The terminal main body part 30 includes: a current voltage control part 31; a current measurement part 33; a voltage difference calculation part 34; a resistance value calculation part 35; a current value calculation part 36; a charging terminal 37; and a data terminal 38. A resistance value R is calculated by the resistance value calculation part 35 on the basis of an inter-terminal/cell voltage difference ΔV between the charging terminal 37 and the battery cell 22 and a current Iof currents, and a proper current value I to be supplied to the battery pack 20 is calculated on the basis of the current value R by the current value calculation part 36.
