Title:
バッテリ装置
Document Type and Number:
Japanese Patent JP6769241
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce variation of a state of each battery module.SOLUTION: The device comprises a battery module 11 connected with a battery sensor 13, and a battery module 12 not connected with a battery sensor. In the battery sensor 13, when an ignition switch 14 is turned on, a supplied current becomes large. A Zener diode 17 and a resistance 16 are arranged between electrodes of the battery module 12. A breakdown voltage value of the Zener diode 17 and a resistance value of the resistance 16 are set to values such that a difference between a value of a first current flowing through the battery sensor 13 and a value of a second current flowing through the resistance 16 becomes lower than the value of the first current when generating power. When the ignition switch 14 is turned off, the breakdown voltage value and the resistance value are set to values such that a difference between a value of a third current flowing through the battery sensor 13 and a value of a fourth current flowing through the resistance 16 becomes lower than the value of the third current.SELECTED DRAWING: Figure 1
