Title:
BATTERY DEVICE
Document Type and Number:
Japanese Patent JP3934522
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a battery device usable even if a part of batteries abnormally generates heat, and facilitating improvement of safety measures.
SOLUTION: This battery device is composed by serially connecting a plurality of the batteries 1. Each battery 1 is equipped with a thermally-actuated switch 2 for cutting off the current carried to the battery 1 to change a preliminary path to a conductive path; a conductor plate 11 connected to a first terminal 7b of the switch 2; a conductor plate 12 connected to a common terminal 6b of the switch 6b; and a conductor plate 13 connected to a second terminal 8b of the switch 2 and usable as the preliminary path. The switch 2 normally brings a moving contact member 10 into contact with a first fixed contact 7a to electrically connect the conductor plates 12 and 11 to each other, and electrically connects the conductor plates 12 and 13 to each other because a bimetal piece 9 is inverted to bring the contact member 10 into contact with a second fixed contact 8a when the battery 1 abnormally generates heat.
