Title:
MANAGEMENT DEVICE AND POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/051574
Kind Code:
A1
Abstract:
In order for a management device to accurately detect cell voltage and also be simplified, the management device (30) manages an electricity storage module (10) having: a first cell module (12) and a second cell module (14) each including a plurality of cells connected in series; and a conductive connection member (16) for connecting the first cell module (12) and the second cell module (14) in series. A voltage detection circuit (32) is connected to the nodes of the respective cells (S1-S4) through voltage detection lines (L1-L6) to detect the voltage of each of the cells (S1-S4) and the voltage at both ends of the connection member (16). A control circuit (34) distinguishes between and recognizes the voltage of each of the cells (S1-S4) and the voltage at both ends of the connection member (16), which are detected by the voltage detection circuit (32).
