Toyota Home Announces New Home Energy Management System

Toyota Home, Denso Corporation, Misawa Homes and Shin-KobeElectric Machinery have jointly developed a 7-inch touch-screen controlled HomeEnergy Management System (HEMS) that enables central monitoring and control of home energy supply and consumption. The system can be linked to solar power sources, EcoCute CO2-based heat pump water heaters, rechargeable batteries for home power storage, and electric and plug-in hybrid vehicles. It is the first such commercially viable system in Japan that enables residents to recharge electric vehicles and also to draw energy from such vehicles to power home devices during power outages.

The system also enables users to monitor energy use in individual rooms, displays previous month and year-on-year comparisons of energy use, and provides readings on water and natural gas consumption.
