- Toyota launches a residential use battery energy storage system.
- The battery has a capacity of 8.7kWh and an output of 5.5kW.
Toyota has introduced a battery energy storage system for residential use. This design is based on the concept of “safe, long service life, high-quality, good value for the price, and high performance,” the company announced in a press release.
According to the manufacturer, the O-Uchi Kyuden System utilises many years of electrified vehicle development and onboard parts. It is intended for normal usage (off-peak electricity, support of home photovoltaic system and EV charging) and as an emergency electricity source (during power outages caused by natural disasters).
The battery capacity is 8.7kWh, while the power output is 5.5kW.
According to the developers, an interesting element of the Toyota O-Uchi Kyuden System is the bi-directional vehicle-to-home capability (up to 1.1 kW output) using an AC charging inlet and a special adapter.
“Unique to Toyota, the system supports supplying twice the power from electrified vehicles (HEV, PHEV, BEV, FCEV) at 100V AC and can use electricity stored in electrified vehicles as a backup power source during power outages, allowing users to live with peace of mind.”
At present, the Toyota O-Uchi Kyuden System is available only in Japan. However, the company recently began to take orders, while sales will start in August through home builders and general construction companies.
