INSPECTION DEVICE AND INSPECTION METHOD OF BATTERY MONITORING DEVICE

To provide an inspection device and an inspection method with which it is possible to inspect the accuracy of a cell voltage measured by a battery monitoring device accurately in a short time.SOLUTION: In an inspection device 1, an input voltage calculation unit 24 calculates an input voltage value V3 that is inputted from a power supply 12 to a battery monitoring device 3 via a detection line 2, on the basis of a measured value V2 of an output voltage of the power supply 12 measured by a voltmeter 13, a measured value I of a current flowing in the detection line 2 measured by an ammeter 14, and a resistance value R of the detection line 2. An inspection determination unit 25 compares the calculated input voltage value V3 calculated by the input voltage calculation unit 24 with an input voltage measured value V4 measured via the detection line 2 by the battery monitoring device 3, and inspects the voltage measurement characteristic of the battery monitoring device 3 on the basis of the comparison results.SELECTED DRAWING: Figure 1 【課題】電池監視装置によるセル電圧の測定精度を短時間で正確に検査可能な検査装置および検査方法を提供する。【解決手段】検査装置１において、入力電圧算出部２４は、電圧計１３により測定された電源１２の出力電圧の測定値V2と、電流計１４により測定された検出線２に流れる電流の測定値Iと、検出線２の抵抗値Rとに基づいて、電源１２から検出線２を介して電池監視装置３に入力される入力電圧値V3を算出する。検査判定部２５は、入力電圧算出部２４により算出された入力電圧算出値V3と、電池監視装置３が検出線２を介して測定した入力電圧測定値V4とを比較し、これらの比較結果に基づいて電池監視装置３の電圧測定特性の検査を行う。【選択図】図１
