Title:
BATTERY MANAGEMENT DEVICE, POWER STORAGE DEVICE, BATTERY MANAGEMENT METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/196438
Kind Code:
A1
Abstract:
A battery management device that manages a power storage element that has a shunt resistor connected thereto. The battery management device comprises: a current measurement unit that uses a pair of signal lines that are connected to either end of the shunt resistor to measure the current flowing in the shunt resistor; a connection line that connects the signal lines to a reference potential source via an opening/closing switch; and a determination unit that, on the basis of the change in the current measured by the current measurement unit when the opening/closing switch has opened/closed, determines whether there is trouble that could lead to failure of the connection between the pair of signal lines as mediated by the shunt resistor.
