BATTERY MONITORING DEVICE AND BATTERY SYSTEM USING SAME |
摘要 |
Provided are a battery monitoring device capable of suppressing a current flowing to individual battery cells and enhancing the safety thereof, even when there is a short circuit, for example, in a connection line connecting substrates having integrated circuits mounted thereon and a substrate having a microcomputer mounted thereon or a connection line connecting the substrates having the integrated circuits mounted thereon, and a battery system using the same. Resistors are provided in a positive electrode input line 13a connecting a positive electrode side of a battery pack group 200 and a total voltage detecting unit 13 and/or a negative electrode input line 13b connecting a negative electrode side of the battery pack group 200 and the total voltage detecting unit 13 and the resistors of the positive electrode input line 13a and/or negative electrode input line 13b are arranged on individual cell monitoring circuit boards 31 and 32. |
