<p>PROBLEM TO BE SOLVED: To provide a battery monitor device that is able to restrict the effect of common noise on a monitor circuit without configuring a ground type filter.SOLUTION: Between a battery pack 1 and a monitor circuit 5, as means for removing common mode noise difficult to remove in a first filter circuit 4, a second filter circuit 3 is added, which is composed of a second resistor 31 provided in each connection line L between the battery pack 1 and monitor circuit 5, and second capacitors 32 connected between connection lines L and connected with each other in series without resistance elements, such as the second resistor 31 and first resistors 41 and 42.</p> |
