Title:
CURRENT MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/012408
Kind Code:
A1
Abstract:
Provided is a current measuring device, which has a variable measuring current range, and is capable of suppressing deterioration of measurement accuracy of a current value. The current measuring device is provided with: a current detection amplifier (151) that detects a current on the basis of a bus bar interterminal potential of a secondary battery (14); and a control unit (152) that controls the gain and the reference voltage of the current detection amplifier (151). The control unit (152) changes the gain and the reference voltage, and also changes the discharge-side measuring current range of the secondary battery (14).
