| 摘要 |
A secondary battery device 1 including multiple protective circuits U<SUB>1</SUB>-U<SUB>3 </SUB>connected in parallel and each having two fuses f<SUB>a</SUB>, f<SUB>b </SUB>connected in series, wherein a terminal t<SUB>c </SUB>of each heater h is connected to a switch element 4 via rectifier element D<SUB>1</SUB>-D<SUB>3</SUB>. Even if a potential difference is generated between terminals t<SUB>c</SUB>, no residual current flows because any one of the rectifier elements D<SUB>1</SUB>-D<SUB>3 </SUB>is reverse-biased.
