Toyota Motor Corporation has developed the “O-Uchi Kyuden System,” a home storage battery system, now open for preorders in Japan.
The O-Uchi Kyuden System uses electrified vehicle battery technology such as Toyota’s battery control to provide a rated capacity of 8.7 kWh and a rated output of 5.5 kWh. By linking with a photovoltaic system, the company says it can supply the appropriate amount of electricity based on customer needs throughout the day and night. Toyota says it believes that using this system will encourage the use of solar power.

The system supports supplying power from electrified vehicles at 100V AC, and can use electricity stored in electrified vehicles as a backup power source during power outages.
In addition, future moves to IoT using a wireless LAN router connected to a hybrid power conditioner allow for storage capacity, operation mode, and other settings to be viewed and set in real-time from a dedicated app on a smartphone or tablet (as of now, only available in Japanese), Toyota says.
