YOKOHAMA, Japan-Japanese automaker Nissan is testing a super green way to recharge your sheet of electric vehicles, solar energy, part of a wider drive to improve energy storage systems.
Nissan leaf in sales late last year, but the automaker is looking to the future about five years time when aging leaves the vehicle may offer an alternative business opportunities for using their lithium-ion batteries for electricity as a storage area.
Nissan Motor Corp. takes note that, when the leaves, the flood of batteries could lead to battery life is longer than the electric vehicles.
Production of electric power and storage are launched in Japan after the 11. March of the earthquake and tsunami caused widespread blackouts in the northeast of the country. She went into meltdown, Fukushima Dai-ichi, after backup generators were destroyed in the tsunami, nuclear power is also the renewal of emergency powers.
In the new system of charging, demonstrated that the journalists Monday, the electricity is created through 488 solar installed on the roof of the building in Yokohama, southwest of Tokyo Nissan headquarters.
Four batteries of the leaves have been placed in a box in the basement as part of the building and saving electricity from solar cells, and that is sufficient to fully charge the 1800 sheets of vehicles per year, in accordance with the Nissan.
While interest is growing in the area of renewable energy such as solar and wind energy, the challenge is to save electricity, which remains costly without a breakthrough in battery technology.
Such interest is likely to grow in Japan due to concerns about the safety of nuclear power plants. Hamaoka nuclear power plant is being shut down due to such concerns, and more may appear.
Other Japanese automakers such as Toyota Motor Corp. and Honda Motor Co., are working on similar projects, such as link hybrids with houses equipped with solar energy as part of a Community called "Smart grids".
Electric cars no pollution or gases, global warming, but they need electricity, whose production mostly relies on polluting oil or natural gas.
Even if the list is ready for disposal, her battery is probably 80 percent of its capacity. On the plus side sheets with its high capacity battery can store the equivalent of two days of the use of household electricity, said Nissan.
"What is important for the Nissan is a solution available through the EDS, step by step," said company Vice President Hideaki Watanabe.
A joint venture with Sumitomo Corp. called 4R Energy Corp. plans to offer electricity storage systems such as the Nissan Directorate-General for enterprise and public facilities as a commercial product by the year 2016.
Nissan also hopes to start selling such storage systems for the regular fiscal year starts in houses April 2012. It will carry out field tests in December, 4R energy President Takashi Sakagami said.
