Title:
MANAGEMENT DEVICE, AND POWER STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/051885
Kind Code:
A1
Abstract:
In this management device which manages a power storage module, a voltage measuring unit (11) measures n voltages of n power storage blocks. A ranking part (143) ranks the n power storage blocks in the descending order/ascending order of magnitude of the measured voltage values. A frequency distribution information generating unit (144), for each of the n power storage blocks, sums up ranks of the measured voltages given within a set period, and generates frequency distribution information of the voltage ranks. An abnormality determining unit (148) detects an abnormality when a normal rank state becomes a different rank state.
