Military forces did not move, forage first. For the electric vehicle is, in order to "popular", the first charge on the need to address this crucial aspect, so that cars have become like a fuel
charge that simple.
And the traditional car "drink oil" is different from electric vehicles (including hybrid cars) need to charge the battery. Currently, however, the charging of electric vehicles face many "roadblocks", above all, the battery itself. For example, the battery costs are high, over a few years in need of replacement, is a no small expense. Battery charging time is too long, but charge a limited number of travel miles, charger ,full power can only be run after a maximum of 100 miles (about 160 km). Let Xi Luota French energy expert, pointed out that the batteries used in electric vehicles are still not resolved the effectiveness and life questions.
Secondly, the charging station is not enough. For example the United States, even in the push for new energy vehicles in California, is also equipped with electric vehicles only a handful of gas stations charging device, which will inevitably lead people to worry about no place to recharge not dare to purchase electric vehicles.
But in the current energy crisis and environmental protection, the dual constraints, the new energy vehicles is to break out a sword. The United States, Germany, France and other countries have begun efforts to explore, trying to remove "roadblocks" to allow electric cars really "run up".
According to the U.S. Ford's research manager Tettey Muller said, Ford is working hard to resolve how to make electric vehicles, access to the road the power network problems. Ford and energy partners, has developed a "car - power grid" digital camera batterycommunications positioning system. The use of this system, drivers can choose how in the most convenient and affordable to the vehicle when charging.
Ford's vision is as long as the owner of a launch vehicle, in-car communications system will locate the road network through a wireless network and connected to the smart meters. Car owners can use the touch screen to choose when and where to recharge the car. Price on the touch screen will be changed at any time to show different time, real-time pricing. Under ideal circumstances, the owner can choose to non-peak hours (usually after midnight and before 6:00) charge, when electricity prices generally the cheapest and is headquartered in Silicon Valley, "a beautiful space," the company proposed a rather innovative electric vehicle charging infrastructure ideas. Julie Mullins company spokesman told Xinhua said that according to this line of thought established network of charging stations, and existing wireless communications network, there are many similarities. For example, the wirelessIBM laptop battery operators to use a network composed of a large number of base stations, to ensure that users within a certain range are available to mobile phone calls. Through distributed in residential areas, commercial buildings, parking lots and government buildings, etc. of hundreds of thousands of charging stations network, the network can give consumers anytime, anywhere within the coverage area for their own electric vehicles charge.
This network will also include a number of battery-replacement stations, they can be Paozhang Tu electric vehicle owners to provide automated service, with fully charged battery to replace the battery under the power is exhausted. The whole process can be less than 2 minutes to complete, consumers do not even need to get off the speed and convenience are superior to existing petrol filling station.
In France, government and enterprises in addition to public places, supermarkets and residential areas are a substantial increase in the number of charging stations, want out of the other solutions. For example in June of this year, Renault - Nissan Group has signed an agreement with French power company, ready to develop a set of car and charging station communication system. The system will be based on the amount of battery power remaining location to the nearest chargingIBM ThinkPad T40 battery station, while the charging stations can also identify the car.
Germany's current idea is that electric vehicles operating in the big cities first, then extended to the inter-city expressway. Berlin, Germany's first city to go in front. Berlin city government in April this year, with the two energy companies, RWE and Vatn Afar, as well as Daimler, BMW, the two major car manufacturers signed an agreement in Berlin to establish at least 550 urban charging stations. Berlin city governmentIBM ThinkPad Z61m battery to provide land, four companies responsible for establishing and charging stations to provide at least more than 1000 test vehicle.
German electrical equipment manufacturer Rittal company's proposed another option is that, in the national popularity of cars in parking lot charging system, the system can automatically monitor the remaining battery power and the required charging time.
German Federal Institute for Energy and the hydropower industry enterprises this year, the joint establishment of the "electric vehicle smart networking" project, aims to develop a charging station system unattended. Charging station automatically identify vehicles and vehicle owners, monthly or IBM ThinkPad T60p batteryquarterly payments accumulated and to help owners of intelligent recognition recently, the fastest charging stations. This will greatly reduce the cost of charging station system to facilitate the owner.
At the same time, Germany have combined the world's vehicle manufacturers to develop harmonized standards for the charging plug. This year's Hanover Industrial Fair, Volkswagen, General Motors, Mitsubishi and other major global automotive manufacturers and power companies have been charging plug on the electric car GM reached a preliminary consensus standards and the development of a sample. At present the company is undergoing final negotiations, such a unified 400-volt plug is likely to become the industry standard, so that the car manufacturers of electric vehicles do not need charging adapter, charging time is also expected to be significantly reduced.
