By pre-burying the wireless charging coil at the bus stop, it is possible to automatically charge when the docking is stopped, and the required cruising range can be supplemented in 30 seconds. Yesterday, the reporter learned from the West Coast New District that Sino-German Ecological Park and Germany's Bombardier PRIMOVE Co., Ltd. recently signed a cooperation framework agreement, the two sides will jointly build the first Bombardier wireless charging experimental line project in China, which is currently the first in Asia and the highest in the world. 200 kW wireless fast charge bus bus line.

West Coast built wireless charging experiment line
The Bombardier Wireless Charging Experiment Line project will each build a medium-distance and short-distance test line. It is expected to be available for 20 wireless charging buses, and the 200 kW wireless charging system developed by Bombardier will be used along the way. The system includes a vehicle identification system disposed under the road surface of the charging station, a wireless charging infrastructure, and an energy receiver, energy storage battery, electric drive system, and the like located on the bus. The “buried†nature of all power and electronic facilities at the charging site makes it possible to zero the footprint of the charging infrastructure in the urban core area. The advantage lies in contactless inductive power transmission, all from invisible power supply equipment hidden under the vehicle and buried under the track, which is immune to any weather and ground conditions.
 Buried coil "life" is guaranteed
The technology lays a power line along the bus and builds a battery sensing system underground in the bus station. The battery is sensed by the magnetic field to transfer power to the vehicle's power receiving system to charge the bus. The unique coil design directional transmission of electromagnetic fields, almost no electromagnetic field is detected in the bus, and the electromagnetic field strength outside the vehicle is only one quarter of the international standard ICNIRP2010, which ensures the green operation of the vehicle. In order to industrialize and bring this technology to market, the patented buried primary coil prefabricated module has undergone a one-year, 1 million-ton, 13-ton axle load rolling test to ensure that the module is at least 20 years old. Service life. All power electronic equipment achieves the highest degree of protection IP68 and adopts the German professional drainage box design, which guarantees safe operation even under heavy rain conditions, which is the advantage of this wireless charging system.
  Charging is completed within 30 seconds of parking
The biggest advantage of the fast wireless charging system is that it can reduce the vehicle charging pressure of the bus hub and distribute the charging facilities to the stations along the line. The system's charging and parking error has reached a revolutionary ±0.6 m (direction of travel) and can be quickly charged at 90% efficiency anywhere within the error range. The passengers in the station can replenish the required cruising range within 30 seconds. The city electric bus will be equipped with a small-capacity fast-charge battery of 60 kWh, eliminating the need to carry two or three tons of power batteries, greatly reducing the weight of the vehicle and saving energy. It consumes 15% and saves space by carrying 12 passengers, thus realizing the original intention of energy saving and environmental protection for new energy vehicles.
Greatly improve operational efficiency
Increasing the charging power and shortening the charging time are very important for electric vehicles. Cobo, vice president of global market strategy of Bombardier, said in a wireless charging technology salon in Beijing in April that wireless charging can greatly improve the efficiency of electric vehicles. In addition, wireless charging is more convenient for future application of automatic parking and automatic driving technology. Take the commercial operation of Bombardier's pure electric wireless charging bus in Germany as an example. It takes 2.7 minutes to 4 minutes to stop at the terminal station, and 200 kW of output power for wireless charging, you can supplement the energy consumed. This is a fully automatic charging method. The bus is used for parking for a very short time. The more convenient the charging, the more you can use these short hours.
 Promote wireless charging car research and development
Bombardier Inc. is the global leader in public transportation technology. Its high-power wireless charging system charges far faster than the 80-kilowatt wired charging system widely used in domestic pure electric buses, making wireless charging not only available in urban micro-circulation lines. It is also suitable for rail transit such as mainline bus lines (such as BRT) and trams. The bus currently using this high-power wireless charging system has opened commercial lines in Berlin, Mannheim and other places, with a cumulative operation of more than 255,000 kilometers.
The National Energy Administration recently issued the "Energy Technology Revolution Innovation Action Plan (2016-2030)". Among the 15 key tasks, the application of wireless charging technology in the automotive field has been mentioned many times. The plan calls for breaking through the wireless charging technology of electric vehicles by 2020, taking wireless charging of electric vehicles as a breakthrough point and application object, developing a high-efficiency, low-cost wireless energy transmission system, and building a demonstration project for wireless charging stations of electric vehicles. This time, the Sino-German Ecological Park in the West Coast New Area will introduce the Bombardier Wireless Charging Experiment Line Project, which will become a demonstration project for the construction of wireless charging stations in China's electric vehicles, and promote the R&D and production of the domestic wireless charging new energy vehicle industry.
