USA: DENSO Unveils Home Energy Management System

Kariya, Japan, Dec 06, 2011 (JCN via COMTEX) — DENSO Corp. has jointly developed a home energy management system (HEMS) with TOYOTA Housing Corp. and Misawa Homes Co. Ltd. The HEMS, DENSO’s first such product of its kind, has optional functions that work with plug-in hybrid or electric vehicles. It will be available in the Japanese market in or after February 2012.

DENSO’s HEMS consists of a control unit and a 7-inch touch panel monitor, installed inside the house. The monitor shows real-time power consumption, helping to remind users to turn off appliances when they are not in use, which also helps them better manage electricity. The monitor can also show electricity consumption in terms of cost and the amount of CO2 emissions that are emitted, as well as historical data, which helps encourage users to be more aware of saving energy. Additionally, the system prevents the circuit breaker from tripping when there is a high electric load.

When the HEMS is connected to an external information center it allows the user to remotely check and switch on and off some home appliances from their smartphone. For example, users could switch on climate control systems, check whether the electrically controlled front door is properly locked, and fill the bathtub with hot water using their smartphone.

Consumers also can use HEMS to schedule a time to charge a plug-in hybrid or electric vehicle battery by coordinating with vehicle battery chargers. That means consumers can schedule battery charging for nighttime, when electricity rates are lower. After signing a contract with a car maker and connecting with the information center, users can remotely turn on the vehicle’s climate control system using the HEMS monitor or smartphone.

DENSO has also jointly developed a household storage battery system with TOYOTA Housing, Misawa Homes and Shin-Kobe Electric Machinery Co. Ltd. When used with the HEMS, the battery, with a capacity of 8.4 kWh, can better control power consumption at home during peak demand hours. The battery system can power a minimum number of appliances, such as room lighting, for a certain period of time*6 in case of a power outrage.

These products utilize the results from the Japan’s Ministry of Economy, Trade and Industry’s “Next-Generation Energy and Social Systems Demonstration
