On April 8, the audience watched a “green electric vehicle†wrapped in “turf†at the industrial fair in Hanover, Germany.
According to Xinhua News Agency, the 2013 Hannover Industrial Fair was officially launched on the 8th. Different from previous years, this year's Industry Fair has set up an independent exhibition hall called "Metropolitan Solution" to show the audience the future of urban environmental protection and intelligence.
Zebra crossings, traffic lights, park benches, shuttle cars... These rarely seen in traditional exhibition scenes appear in the “Metropolis Solutions†showroom. In the 6,000-square-meter exhibition hall, more than 130 exhibitors showcased their products, technologies and solutions designed for the future of the city.
Recharging vehicles with electromagnetic induction
Electric vehicles are considered to be the direction of future automobile development, but charging is one of the obstacles to its development. German SEW Transmission Equipment Co., Ltd. has demonstrated a non-contact charging device that is expected to solve this problem. Different from the existing charging piles, the charging device buries the coils underground and charges the vehicles parked on the ground by electromagnetic induction.
Such devices can be buried in parking lots, taxi stands, bus stops, traffic lights, etc. When the electric car is parked on the charging device, it can be automatically charged. If a dense enough charging device is installed in the city, it will help reduce the demand for onboard battery capacity.
Torsten Gertzmann, project manager of SEW's Urban Logistics and Electric Vehicles, said that this technology has been applied in industrial production areas, such as the factory's automated navigation trucks. The non-contact charging technology is also being tested in parts of the Frankfurt Airport in Germany.
"Building blocks" to build skyscrapers
The Yuanda Group from Hunan, China also has its own views on the future development of urban architecture. The striking position of its booth houses a skyscraper model. This building, known as the “Sky City,†is 838 meters high. The special feature of this tall building is its “building block†style. The main components and internal pipelines that make up the building are first produced and installed at the factory, and then workers are set up on the construction site. The construction process is expected to take about 100 days.
Yuanda staff at the show pointed out that high-rise buildings can solve the problem of scarcity of urban land resources in the future, and modular construction methods also help improve efficiency.
The Siemens exhibit in Germany focuses on the intelligent management of energy in houses. The power of smart houses comes from autonomous power generation systems that use wind energy and solar energy. When the electricity is obtained from the external grid, the computer system in the house can automatically monitor changes in electricity prices and purchase electricity when electricity prices are low. The energy storage device can store new energy and electricity, and can be used for electricity in houses as well as for charging electric vehicles.
Schneider Electric Investment Company brings smart city solutions such as smart grids and smart water management. Exhibitors such as the German Railway Company and the Fraunhofer Company in Germany have also demonstrated their abilities. Although some of their technologies and solutions are still in the conceptual stage, there are also many technical solutions that have been applied in large and small towns.
