Title:
STORAGE BATTERY SYSTEM, RAILWAY VEHICLE, DATA SERVER, AND STORAGE BATTERY SYSTEM CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/034252
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a technology for minimizing an influence on operation, such as power consumption degradation or power deficiency caused by charge/discharge current limitation. Accordingly, this storage battery system is provided with: a battery temperature and charge rate prediction unit that predicts a battery temperature and a charge rate from operation information, storage battery information, and weather information; an overtemperature determination unit that determines whether the battery temperature predicted by the battery temperature and charge rate prediction unit is within a battery usable temperature range; a power deficiency determination unit that determines whether the charge rate predicted by the battery temperature and charge rate prediction unit is a charge rate at which travel is possible; and an upper limit charge current value decision unit that outputs an upper limit charge current value at which the battery temperature is determined to be within the battery usable temperature range by the overtemperature determination unit and at which the charge rate is determined to be the charge rate at which travel is possible by the power deficiency determination unit.
