Title:
STORAGE BATTERY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/136908
Kind Code:
A1
Abstract:
A storage battery device according to the embodiments of the present application is installed in a vehicle and supplies power to in-vehicle equipment. The storage battery device comprises: a plurality of battery units that are connected in parallel, each having a plurality of battery cells connected in series between a pair of first input/output voltage charging/discharging terminals, and each supplying low voltage power via the pair of charging/discharging terminals; and a DC voltage converter that is capable of supplying power by subjecting the supplied power from the plurality of battery units to DC voltage conversion and outputting the converted power to the vehicle side via the charging/discharging terminals, and is capable of subjecting supplied power input from the vehicle side via the charging/discharging terminals to DC voltage conversion and supplying the converted power to the plurality of battery units. Thus, it is possible to simultaneously supply low voltage power and high voltage power while also ensuring reliability.
