Abstract
A current measurement devicefor measuring the current of a power storage element comprises a measurement resistor unitthat is positioned on a current path and comprises a resistor, a pair of detection points Pa, Pb that are positioned on the current path on both sides of the resistor, a current detection unitthat comprises a pair of voltage input unitsA,B that are connected to the pair of detection points Pa, Pb and detects the current of the power storage element from the voltage difference between the pair of detection points, and a ground connection point Pg that is connected to a common ground GND with the current detection unit. The resistance Rga along the current path X to the ground connection point Pg from the detection point Pa from among the pair of detection points Pa, Pb that is closest to the ground connection point Pg is smaller than the value obtained by dividing the input voltage tolerance Vm of the current detection unitby a prescribed current of the power storage element.
