Title:
BATTERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/087128
Kind Code:
A1
Abstract:
In a battery system, a BMS calculates the maximum charge rate indicating the maximum value among present charge rates of a plurality of respective secondary batteries constituting an assembled battery and the minimum charge rate. A normal time waveform signal is generated that is a waveform signal displayed in a charge rate display range in which a full charge rate obtained when a secondary battery is fully charged is set as an upper limit and an empty charge rate obtained when a secondary battery is emptily charged is set as a lower limit. In the normal time waveform signal, the maximum charge rate is set as a maximum peak and the minimum charge rate is set as a minimum peak. The normal time waveform signal is displayed in the charge rate display range.
