Title:
VOLTAGE DETECTOR
Document Type and Number:
Japanese Patent JP2016017942
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a voltage detector capable of eliminating the influence of filters provided to correspond to adjacent unit cells in a configuration of diagnosing the voltage output function of each of unit cells of a battery pack by comparing a voltage of the unit cell output from a normal passage with a voltage output from a diagnostic passage.SOLUTION: In a case of diagnosing a voltage output function of a second unit cell V2, a diagnosis is carried out in a state of connecting a capacitor C21 between normal passages P21 and P22 and, at the same time, connecting a capacitor C22 between diagnostic passages P12 and P31, and disconnecting capacitors provided between the normal passages and the diagnostic passages adjacent to one another. By doing so, it is possible to ensure the diagnosis of voltage output functions of respective unit cells V1 to V8 without the influence of filters provided in the normal passages and the diagnostic passages adjacent to one another.SELECTED DRAWING: Figure 2
