Toyota has developed batteries based on the concept of "safe, long service life, high-quality, good value for the price, and high performance" so that customers can use them with peace of mind. This technology utilizing many years of electrified vehicle development as well as on-board parts and units has been used to create the O-Uchi Kyuden System, a home storage battery system.

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. This ensures safety and provsuppliessupply of electricity to the entire home not just in normal situations, but even during power outages caused by natural disasters.

In addition, by linking with a photovoltaic system, it can supply the appropriate amount of electricity based on customer needs throughout the day and night. Toyota believes that using this system will encourage the use of solar power which is renewable energy.

Unique to Toyota, the system supports supplying power from electrified vehicles (HEV, PHEV, BEV, FCEV) at 100 V AC, and can use electricity stored in electrified vehicles as a backup power source during power outages, allowing users to live in peace of mind.

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.
