Title:
A variable disconnection device and the variable disconnection control method of a battery system
Document Type and Number:
Japanese Patent JP6198778
Kind Code:
B2
Abstract:
Disclosed are an apparatus and method for variably controlling the disconnection or connection of switch connections between battery units in a large battery system based on the degree of a sensed dangerous external situation to convert the battery system into a small capacity and low voltage state. The apparatus includes: switches provided to interconnection lines between battery assembly units to electrically connect or disconnect the interconnection lines; a switch control module adapted to apply on/off signals to the switches; and a disconnection control module adapted to control the switch control module based on a sensed dangerous level to vary the position and number of the target switches to be opened or closed and the disconnection intervals. According to the apparatus and method, dangerous external situations of a large battery system can be sensed and the disconnection of physical connections between the battery units can be variably controlled. Therefore, the battery system can be stabilized into a small capacity and low voltage state.
