Toyota releases storage battery system for residential use

Japanese company Toyota Motor Corporation has unveiled the O-Uchi Kyuden System, a storage battery system for residential use based on their electrified vehicle battery technology. The battery system is claimed to be safe, has a long service life, is high-quality, has good value for the price, and has high performance.

The O-Uchi Kyuden System provides a rated capacity of 8.7 kWh and a rated output of 5.5 kWh. This ensures safety and provides a supply of electricity to the entire home, not just in normal situations but even during power outages caused by natural disasters.

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. Installed on the outside of the home, the system also supports supplying power from electric 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.

The O-Uchi Kyuden battery system itself measures 1,142 x 341 x 432 mm and weighs 142 kg, while the hybrid power conditioner and vehicle power supply adapter together add 42 kg extra. It has an operational ambient temperature of -20 to 45-degree Celsius (-4 to 113-degree Fahrenheit).

The home storage battery system is now available for pre-orders, and sales in Japan will begin in August through home builders and general construction companies.
