Nissan and 4R Energy Develop new Solar EV Charging System


Nissan and 4R Energy Corporation today announced that the two companies have developed a charging system for electric vehicles that combines a solar power generation system with high-capacity lithium-ion batteries. Testing of this new charging system began today at Nissan's Global Headquarters in Yokohama.

With the new charging system, electricity is generated through solar cells installed at Nissan's Global Headquarters, and is stored in lithium-ion batteries which are equivalent to four units of Nissan LEAFs. With seven charging stations (three quick charge, four normal charge) located in the headquarter grounds, the total electricity that can be generated and stored is the equivalent to fully charging approximately 1,800 Nissan LEAFs annually.

This new system will enable electric vehicles, which do not emit any CO2 when driven, to be charged through a completely renewable energy source. This is one solution to create a cycle where CO2 emissions resulting from driving is zero. By using the same lithium-ion batteries in electric vehicles as stationary storage batteries, electricity can also be supplied to EVs regardless of the time of day or weather, enabling efficient use of renewable energy sources.

4R Energy Corporation, a joint venture established by Nissan and Sumitomo Corporation in September 2010, has already started tests on a compact electricity storage system installed with second-life lithium ion batteries previously used in Nissan LEAFs. Based on the outcome of this larger system, 4R Energy plans to enter the market of mid-sized electricity storage systems for commercial and public facilities.

Nissan and 4R Energy Corporation will continue various efforts to help move toward a sustainable, zero-emission society.

Toyota City smart homes to use EVs for standby power




The Toyota City Low-Carbon Society Verification Promotion Council, an organization of 26 entities, including Toyota City and private companies, has completed model smart houses*1 in the Higashiyama and Takahashi districts of Toyota City for testing energy-management systems and has started trial operations under the Verification Project for the Establishment of a Household and Community-based Low-Carbon City in Toyota City, Aichi Prefecture.

1. Project Description

The Verification Project is being conducted as a Next-Generation Energy and Social System Demonstration project (a five-year project running from 2010 to 2014) of the Japanese Ministry of Economy, Trade and Industry (METI). Toyota City was selected as a demonstration area for the Verification Project in April 2010 to support development of testing equipment and information systems. The key feature of the project is the pursuit of optimal energy use in living spaces at the community level.

1) Optimization of Household Energy Use
Household energy consumption is increasing. The Verification Project seeks to coordinate supply and demand within communities in conjunction with the use of both grid and renewable natural energy to achieve local production of energy for local consumption. Verification of distributed power supply from storage batteries and reduced carbon emissions from homes will be carried out, with the overall aim to reduce household carbon dioxide emissions by 20% (70% or more for smart houses).

2) Achieving Compatibility between Environmental Preservation and Resident Satisfaction
The Verification Project will predict and control energy consumption and support activities using an original energy data management system (EDMS) and home energy management system (HEMS). The aim is to maximize the use of renewable energy while achieving energy savings and conservation that maintains community quality-of-life levels and comfort.

3) Creation of Low-Carbon Traffic Systems
In addition to reducing the carbon dioxide emissions from road traffic through the introduction of plug-in hybrid vehicles (PHVs), electric vehicles (EVs), and fuel cell vehicles (FCVs), the Verification Project will use IT and ITS technologies to efficiently integrate motor vehicles and public transportation for commuting and other travel with the aim of reducing carbon dioxide emissions in the transport sector by 40%.

2. Verification of the Household and Regional Energy Sectors

This year, the Verification Project’s second year, marks the start of the testing phase for energy management at the household and community levels. Sales of the smart houses, where trial operation of the system will be conducted, began on June 3. The first phase of verification testing will begin in September at 14 of the smart houses.

In each house, a HEMS will link energy-generating devices (solar cells, fuel cells, etc.) and energy storage devices (household storage batteries, EcoCute heat-pump water heaters, etc.) in the home with next-generation vehicles (PHVs and EVs) and intelligent household appliances to optimize and make possible visualization of electric-power supply and demand and control of individual household devices. Storage batteries connected to and controlled by the HEMS will support low-cost and low-carbon energy consumption in the home and can serve as an emergency power source.

On the community level, the EDMS will coordinate the balance of the electric power supply and demand within the region by linking homes, convenience stores, schools, and the like with the aim of achieving local production of energy for local consumption by the community. For example, if a shortage of power generated by solar panels in the community is predicted, residents will be advised to limit their energy consumption, and eco-points will be awarded for conduct in accordance with those recommendations. Also, information concerning electricity usage and accumulated eco-points can be sent to specialized terminals, PCs and smart phones to encourage ongoing environmentally-friendly behavior that can be reasonably carried out.

In addition to charging PHVs and EVs from household electricity, V2H*2 (vehicle to home) supply of electric power from motor vehicle batteries to the home will also be tested. During normal times, vehicle batteries can store excess power from the home and from the community, contributing to efficient energy usage. And during emergencies, the batteries support regional energy autonomy by acting as mobile power sources.

Mitsubishi Debut Solar-Powered Vehicle Charging Station


Mitsubishi Electric & Electronics USA, Inc. (Mitsubishi Electric) and Mitsubishi Motors North America, Inc. (MMNA) today debuted a solar-powered charging station for electric vehicles at the MMNA headquarters in Cypress, California. This charging facility, the first of its kind in Cypress, symbolizes MMNA's commitment to electric vehicle readiness, and will help kick off the preparations as certified Mitsubishi dealers become EV-ready in anticipation of the scheduled launch date of Mitsubishi i for each state. The charging station is powered by 96, 175W photovoltaic modules from Mitsubishi Electric.

This charging station will help support CHAdeMO compatible electric vehicles such as the Mitsubishi i, which will arrive in showrooms in November of this year. Mitsubishi i vehicles are now being reserved by prospective owners through a pre-order process available at i.mitsubishicars.com.

Able to charge up to four vehicles at once, the station features three types of chargers with different voltages: standard level 1 voltage (110v) will deliver a 100 percent charge in 22 hours on the new Mitsubishi i; level 2 (220v) which can charge the vehicle in six hours; and level 3 CHAdeMO Quick Charger, which can charge to 80 percent battery capacity in 25 minutes.

The DC Quick Charger used for the Cypress charging station is manufactured by the Eaton Corporation, and is the first-of-its-kind CHAdeMO Quick Charger certified for U.S. sale and public utility. The actual installation of the charging equipment and the supporting electrical infrastructure was handled by Rogers Electric. The twin-arch structure for the charging station was designed by California Green Designs.

The charging station is the first such collaboration between the two similarly named companies, whose headquarters are just a few blocks apart in northern Orange County. Situated near the junction of the 405 and 605 freeways, the hope is that the Cypress charging station, with its Quick Charge capability, can serve as a gateway charging pad for Mitsubishi i users commuting between Los Angeles and Orange counties.

"This project will build awareness of solar power's versatility and efficiency," said Katsuya Takamiya, president and chief executive officer, Mitsubishi Electric & Electronics USA. "As electric vehicles' popularity grows, we expect to see more charging stations at large employers, automobile dealerships, shopping centers and schools, where cars can charge while people work, shop or study."

Mitsubishi Motors North America President Yoichi Yokozawa said "We hope that our dealers, learning institutions, and municipalities will look to this technology with a keen eye towards the future, and bear in mind that the gradual acceptance of the pure-EV transportation will be aided by increasing the number of facilities like this one."

Mitsubishi Electric's solar panels are made with 100 percent lead-free solder, and have one of the higher sunlight-to-energy conversion ratios in the industry, adding to the project's efficiency and sustainability.

Zero Emission Hypersonic Plane Could Fly London-Sydney in 3.5 Hours [video]



European aerospace giant EADS has unveiled its "Zero Emission Hypersonic Transportation" (Zehst) rocket plane it hopes will be able to fly from Melbourne to London in under 3.5 hours by around 2050.

The trip between Paris and Tokyo could be completed in under 2.5 hours.

"I imagine the plane of the future to look like Zehst," EADS' chief technical officer Jean Botti said as the project was announced at Le Bourget airport the day before the start of the Paris International Air Show.

The low-pollution plane to carry between 50 and 100 passengers will take off using normal engines powered by biofuel made from seaweed before switching on its rocket engines at altitude.

The rocket engines, powered by hydrogen and oxygen whose only exhaust is water vapour, propel the plane to a cruising altitude of 32 kilometres (20 miles), compared to today's passenger jets which fly at around 10,000 metres.

"You don't pollute, you're in the stratosphere," Botti said.

To land, the pilot cuts the engines and glides down to Earth before reigniting the regular engines before landing. EADS hopes to have a prototype built by 2020 and for the plane to eventually enter service around 2050. The project is being developed in collaboration with Japan and uses technology that is already available.

A four-metre model of the plane, which looks similar to the now defunct Concorde supersonic jet, will be on show at Bourget for the biannual aerospace showcase which begins on Monday and opens to the general public on Friday.

Hyundai Heavy moving into tidal power business



Hyundai Heavy Industries (HHI), the world’s biggest shipbuilder, completed the site trial of a prototype 500 kW tidal current power system at Uldolmok Passage in Jeollanam-do, southwest Korea.

Tidal current power is a form of hydropower that converts the kinetic energy of the tidal currents into electricity using turbines. Hyundai Heavy’s prototype tidal current power system directly connects a tidal turbine, a gearbox, and a generator for power transmission. The system can operate regardless of current direction using a specially designed turbine system.

After completing factory and basin tests last year, HHI successfully produced target power generation from site trials this May. Based on the data collected from the trials, Hyundai Heavy plans to pursue tidal current power farm projects by scaling up power generators. The Ulsan-based company is also part of the government-backed National Project for Developing MW-class Tidal Current Power Farm with other Korean companies. The project is due to be completed in 2014.
