Suggestions for Energy Conservation and How to Use PHV, Tailored to Each Household's Lifestyle

The Energy Data Management System (EDMS), designed to enable the region to minimize its carbon footprint and equalize the use of electric power, has begun operating as part of the Toyota City low-carbon society system verification project "Smart Melit (Smart Mobility & Energy Life in Toyota City)." A service began in November 2014 that offers recommendations to covered households. Based on the amount of electric power each household uses and on its plug-in hybrid vehicle (PHV) usage status, it suggests ways to save electricity and the best times to charge their PHVs, among other information.

Initiative Picks up Pace to Build EV Car Sharing Business

Toyota Motor's Ha:mo RIDE is a super-compact EV sharing service that is part of Toyota City's low-carbon society system verification project "Smart Melit (Smart Mobility & Energy Life in Toyota City)." The service is now expanding its fleet of vehicles as well as parking space and stations with recharging equipment. With about 3,300 individual members and a growing number of corporate members, Toyota Motor is stepping up its initiatives for building the Ha:mo RIDE business.

Environmentally Progressive City Conference Held with UN as Co-Host

Toyota City held Toyota World Environment Week 2015 in mid-January. National and local governments from around the world as well as international organizations came together for nine days of events and meetings. The central event was the High-Level Symposium on Sustainable Cities, co-hosted by the United Nations and Toyota City. Besides that, citizens took part in the Toyota Business Fair, the Forum on Environmentally Progressive Cities and Disaster Prevention, and the Hospitality Tea Service and Lecture. Visitors could also take a test drive in a fuel cell vehicle (FCV). Announcements were made for audiences in Japan and abroad of initiatives for the environment in Toyota City and the findings of the Toyota City low-carbon society system verification project "Smart Melit (Smart Mobility & Energy Life in Toyota City)."

About the city

A regional urban center in the north of Aichi Prefecture, Toyota City is the prefecture's largest city in terms of area and boasts its second-largest population. Toyota City is an in-land industrial city situated on the middle stretches of the Yahagi River, and is known for being a "company castle town," the location of the headquarters of Toyota Motor Corporation. As a model city for the EV&PHV Town Concept and ITS operational experiments, Toyota City has commenced the introduction of next-generation vehicles and transport systems, and is working towards the realization of a low-carbon society.

Overview of the project

This project seeks to envision the home environment in ten years' time, when there will be introduction of renewable energy and more extensive use of various energy-saving and energy storage devices. The power transfer patterns of a variety of devices, including next-generation vehicles, will be integrated and controlled by HEMS, enabling users to enjoy a pleasant and convenient low-carbon lifestyle without waste and without effort. Advancing the introduction of next-generation mobility modalities, the building of public transport infrastructure, and the presentation of new forms of transport use in tandem, we are aiming to become the city with the world's highest level of harmony between cars and people. We will use a range of energy sources including city gas and biomass, and make full use of heat and electricity. We will offer a variety of incentives to encourage citizens to engage in their own carbon-reduction activities, at the same time as making energy use visible, providing support for action, and enabling control of energy use through familiar terminal devices, making it possible to select from an optimal menu of low-carbon activities for the entire living environment with a minimum of effort.

Project orientation

Focusing on the household sector (residences and transport), the project seeks to identify medium-term technological issues based on an image of the household in ten years' time, when, for example, photovoltaic (PV) generation will be widespread and grid parity will have been established. Without rushing to raising the social cost, we will develop low-carbon systems that present the overall optimum at the level of the community as a whole. In concrete terms, we will offer highly convenient and satisfying incentives (such as "eco points") for activities conducted by citizens that contribute to reducing carbon (saving energy, reducing the load on the power system, making effective use of green power, etc.) in order to study the change in citizens' behavior and the magnitude of its impact. In terms of effective incentive design, in addition to introducing various devices and systems to the city, we will establish a system in which citizens obtain data on personal energy consumption and behavior to enable us to reduce carbon at the same time as ensuring the satisfaction of our citizens.
