Low temperature-induced cell efficiency has drastically reduced Frost challenges facing new energy vehicles

United States many State Governments are hoping that through the development of new energy vehicles to improve air quality, but because the battery efficiency will be greatly reduced in a low temperature environment, give them an unexpected challenge.

At present, the United States in addition to California, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Rhode Island and Vermont in 9 States reference to the emission standards of the California electric car and hybrid car sales target. But the problem is that other than Oregon, other State lacks the warm climates of California. As the temperature drops, green power generation relies on a chemical reaction efficiencies will also be reduced. In United States Automobile Association tests, an electric car to 75 degrees Fahrenheit (about 24 degrees Celsius) when the range is 105 miles (about 169 km), 20 degrees Fahrenheit (about 7 degrees c) when it will decrease to 43 miles (about 69 km)-fell by as much as 60%.

That raised concerns in places like Maine, Maine is the United States one of the States with the highest degree of agricultural, where residents often need to drive long distances to get to work, shopping and entertainment venues. "Someone said, don't worry. "The Maine Automobile Dealers Association President Tom Brown (Tom Brown) referring to battery life problems, said. But he said, "California is not Maine, 5 cities they block more people than our State as a whole. ”

These 9 States the same reduction targets as California, they chose the California emissions standards, and did not comply with looser federal standards. Representatives United States 8 North-Eastern State of the nonprofit Northeast States coordinated air use management organization (the Northeast States for Coordinated Air Use Management) Transport Department mate·suoluomeng (Matt Solomon) said: "electrification is part of the programme. ”

California's zero emission vehicle sales in the United States totals. In the area of electric cars and hybrids sales target from the current less than 1%, 15% of up to 2025. These goals came from a legislation adopted in 2003 by means of greenhouse gas emissions by 2050 compared with 1990 and 80%.

Auto manufacturers are in accordance with the established plan to achieve compulsory sales targets, if you can't finish the target, each sold fewer cars was about to face a fine of $ 5000. Now in 3 types of cars on roads are in line with the zero-emission standard: Nissan Leaf and Tesla zero-emission car, the Chevrolet Volt and other electric hybrids that switch between engines and fuel and hydrogen-fueled cars such as Toyota Mirai. (Because the Tesla to sell electric cars only, so the company has also developed a sideline, to the introduction of zero-emission vehicles automakers sold. )

While 9 States adopted the same targets, but progress has lagged behind the warm climates of California. "The introduction of mandatory technical challenges is picking winners and losers. "The global automotive manufacturers Association President and CEO yuehan·bozela (John Bozzella) says," North-East face unique challenges. "Bozela and United States Automobile Manufacturers Association in 2014, successfully resisted the New Hampshire drieularochelle along with the other New England States plan to adopt the California standard.



Officials hope that tackling climate change through improved batteries. "Mileage longer, more advanced batteries, the problem is less. "Solomon said that Tesla has launched a range of 200 miles of cars, and promised as early as 2016 introduction of lower-priced models. GM says Volt planned for the next year, similar to the company's endurance. "Hundreds of miles of range would be a huge revolution. "The United States Director of the natural resources Defense Council energy and transport program luolande·Huang (Roland Hwang) said.

Follow the California commitments of those States set up charging stations and other infrastructure, electric car drivers to help. But the environmental lobby in New York bide·yiwannuoweici (Peter Iwanowicz) that does not seem to be a State willing to reduce sales target. He said: "If you have these goals, but science tells you to do, it should act now. ”
