Electric vehicle battery question

Electric car battery replacement does not extend to insurance, coordinated "quick Paige" to renewal

Purchase of electric vehicle batteries replaced under warranty due to a fault, but the piece of replacement with a new battery has a fault only a few months, consumers find the aftermarket for replacement again but was denied. Yesterday, Nanchang Xiong public complaints to the press.

According to Xiong introduced in March 2007 he was in the way of the electric car Nanchang Hongseong a street value of 1,900 yuan to buy a car "quick Paige" brand electric vehicles. Car is here when the businesses on the promise of electric vehicle battery pack repair for 1 year. This year in January, Xiong suddenly found themselves unable to charge batteries for electric cars, so he sent the car, "Paige speed electric car sale center in Nanchang," replaced a new battery. "The new battery only used a few months time it fails, even if the electric charge of a night no electricity running only 2 km of" So, Mr. Xiong electric cars once again sent to after-sales center. After repair, maintenance personnel found four batteries in a group has been damaged, replace all batteries must be charged. "Only for the battery has problems, why should he be charged?" Obviously, Xiong difficult to accept aftermarket replacement battery charging requirements, and he called for help.

Yesterday morning, the reporter went to the No. 50, Nanchang forward "speed electric vehicles Nanchang Paige sale center." Person in charge of the center, surnamed Wang, told reporters in a years electric cars to replace the battery warranty period is free, but to replace the battery warranty is not extended warranty period, and this is guild regulations of electric vehicles. However, the reporter but never learned the business sector, Xihu District of Nanchang, the batteries also are part of the product, under the "three guarantees" the relevant provisions of law, the product should be re-calculated replacement parts warranty.

Finally, under the coordination of the press, "Paige speed electric car sale center in Nanchang," the manager Wang agreed to Mr. Xiong replaced free of charge a new battery.

California Fuel Cell

California Department of Food and Agriculture Organization to join the California Fuel Cell Partnership

California Department of Food and Agriculture (CaliforniaDepartmentofFoodandAgriculture) joined the California Fuel Cell Partnership (CaliforniaFuelCellPartnership).

California Fuel Cell Partnership has 31 members, including auto manufacturers, energy providers, government agencies and fuel cell technology companies. California Fuel Cell Partnership hydrogen is mainly to promote the commercialization of fuel cell vehicles, energy efficiency, reduce air pollution and greenhouse gas emissions to a sustainable energy future.

California Food and Agriculture Department will use its technology to help California establish appropriate design standards, the establishment of hydrogen fuel sampling and testing procedures.

Now, California has more than 200 cars hydrogen fuel cell vehicles in operation; total of 25 hydrogen stations.

New high efficiency solar cells 40.8%

Two years ago, Boeing - Spectroscopy Laboratory scientists will improve the efficiency of solar cells to 40.7%, which panels using different semiconductor materials, various materials for the formation of a special thin interface. Such a structure makes solar panels, "tolerance" in a larger spectral range. Compared with ordinary solar cells can "seize" the sun more wavelengths of photons. Recently from the U.S. Department of Energy Renewable Energy Laboratory (NREL) scientists to increase that figure by 0.1% to 40.8%.

This figure is equivalent to 326 in the strength of a typical sunny weather sunshine obtained under a simulated environment, though only in comparison with the previous record increase of 0.1%, but claimed the new solar panel is completely different structure, using gallium indium phosphide and gallium indium arsenide material strength of the spectrum is divided into three equal parts, solar panels for each of the three parts of the semiconductor junction concentrated absorption. Alleged new extremely thin solar panels, other than before the cost also reduced. NREL hope that the solar cell can be quickly applied to the satellite and terrestrial solar power plants in the past.
