Title:
MANAGEMENT DEVICE AND POWER SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/159218
Kind Code:
A1
Abstract:
In order to provide a technology capable of more reliably detecting disconnection, a management device (30) comprises a voltage detection circuit (32) and a plurality of capacitor circuits (CA1-CA4). The voltage detection circuit (32) is connected, by voltage detection lines (L1-L5), to each node in a plurality of cells (S1-S4) connected in series and detects the voltage of each of the plurality of cells (S1-S4). The plurality of capacitor circuits (CA1-CA4) are each connected between two voltage detection lines connected to each cell (S1-S4). Two capacitor circuits corresponding to two adjacent cells have mutually different capacitance values.
