Title:
ABNORMALITY DETECTION DEVICE FOR BATTERY PACK
Document Type and Number:
Japanese Patent JP2014183671
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an abnormality detection device for a battery pack capable of appropriately detecting open abnormality of an inter-stack wire 60.SOLUTION: A positive electrode terminal of a first cell group CG1 and a negative electrode terminal of a second cell group CG2 are connected by the inter-stack wire 60. A third electric path L3 closer to a first monitor IC 30a than a third resistor R3 and a fourth electric path L4 closer to a second monitor IC 30b than a fourth resistor R4 are connected by a bypass path 62. The bypass path 62 then includes a serial connection body of a first Zener diode 70a and a second Zener diode 70b of which the anodes are connected with each other.
