Title:
COMBINED ELECTRICITY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/093048
Kind Code:
A1
Abstract:
This combined electricity storage system is configured by connecting a capacity battery pack and a power battery pack in parallel via a capacity battery pack switch and a power battery pack switch, wherein: when charging the combined electricity storage system, charging is started after turning on the capacity battery pack switch and the power battery pack switch; and when the current flowing through either the capacity battery pack or the power battery pack has become the discharge side, the switch of a battery pack, the current flowing through which has become the discharge side, is turned off. This can provide such a control that increases charging power as much as possible in a short time with a configuration in which the capacity battery pack and the power battery pack are in parallel.
