Charging while driving is the electric vehicle’s future
According to the British “Financial Times” reported on the 29th, the US chip maker Qualcomm recently announced the electric car wireless charging technology, can help the car in the process of driving to complete the charge.
Recently in Paris, the US chip maker Qualcomm announced a traditional core business – smart phone processors and computers – far from the technology: electric car wireless charger.
On the 100-meter test road, the company showed that two Renault Kangoo trucks were able to get electricity directly from the ground under the ground. The show marks a breakthrough in a technology that could change the economics of electric vehicles.
Electric car sales are on the rise as carmakers have introduced new models that can rely on a range of batteries for more mileage. But the lack of charging infrastructure (coupled with price and battery mileage factors) is still an important obstacle to the popularity of electric vehicles obstacles.
Analysts predict that once the price is flat with the traditional internal combustion engine car (which may take 5 to 10 years), the sales of the battery-driven car will take off.
As a result, the industry is turning its attention to the problem: one day on the road driving electric vehicles will be more than the traditional charging equipment carrying capacity, then how to do?
“We will have to think about new things,” said Edouard Fischer, director of Sanef, a freeway operator in France. “We have to be 10 to 10 years old,” said Edouard Fischer, director of the French freeway operator Saref. 15 years after the things that will happen to be prepared.
How will autopilot change our lives?
Automated driving will improve traffic congestion and reduce traffic accidents, but they will also have a mixed impact on public transport, the real estate market and health.
Sanef sets a charging pile every 80 kilometers in its 2000 km road network. Fisher said in the UK’s Financial Times, Future of the Car Summit that the number of electric vehicles traveling on the company’s roads has increased by 250 percent over the past year.
But at some point in the future, fixed pile will no longer be able to cope with a large number of electric vehicles on the road. With the following charging equipment, in the high-speed road laying under the cable system can give the car into the amount of electricity, so that the car in the way of running power shortage.
The car will travel hundreds of kilometers on this freeway, and the remaining electricity will be the same as when it enters the freeway. This may change the mileage of electric vehicles, because they must now stop before the battery is used to charge, which extends the long journey driving time.
Reynolds electric vehicle director Gilles Norman (Gilles Normand) said that the development of the field “very, very fast.” Daimler, owner of BMW and Mercedes, has developed a sensor board for plug-in hybrids that allows them to be wirelessly charged. Nissan (Nissan) in 2010 demonstrated its first prototype system. The car stops at the top of the sensor board, and the electricity is transmitted wirelessly to the car.
Norman pointed out that three years ago, Renault’s sensor board needs only half a mile from the ground to connect. Today, the distance is 4 cm, the required weight of the equipment is also much lighter than 3 years ago.
Although this technology may run smoothly in the garage, it would be more difficult to make the system perfect and safe to run on highways.The induction device on the ground must be able to recognize and charge the car before the vehicle is driven, which requires a nanosecond reaction time. Qualcomm said its new system can charge high-speed cars, two cars can be in the same paragraph on the road charge.
There are other logical barriers before the device is transferred from the test road to the road. A lane must be reserved for use by cars with road charging equipment, otherwise the sensor must also be able to identify whether it is not a non-rechargeable vehicle.
The car will also be charged during the journey to charge the cost, which requires the car to install the instant payment system.
Installation of cables and sensors need to destroy the highway, the cost will be huge, even if the system is only implemented in Europe, also need to cost tens of billions of euros.
