Where to Charge electric Cars?
What if could recharge while speeding along the highway — freeing drivers to go greater and greater distances without having to stop and plug in?
Researchers are working on it. A team from Stanford University reported their latest advance in a research paper published Thursday in the journal Nature. In the paper, they share their progress towards developing new technology to wirelessly deliver electricity to moving objects — namely, electric vehicles. As the technology stands now, electric cars generally require hours in one place in order to charge.
In a preliminary experiment, the researchers transmitted electricity wirelessly to a moving LED lightbulb. The experiment was limited, involving only a one milliwatt charge, whereas electric cars tend to require tens of kilowatts of energy to function.
"In theory, one could drive for an unlimited amount of time without having to stop to recharge, " Shanhui Fan, senior author of the study and a professor of electrical engineering at Stanford University, said in a statement. "The hope is that you'll be able to charge your electric car while you're driving down the highway. A coil in the bottom of the vehicle could receive electricity from a series of coils connected to an electric current embedded in the road."
The researchers further detailed their process in executing the so-called "mid-range wireless power transfer." They said their method is more efficient thanks to a voltage amplifier and feedback resistor, which calibrate frequency without human assistance.
The team is now moving on to next steps: trying to dramatically increase the amount of energy that can be transferred, maximize the transfer distance, and boost efficiency in their process. The new research builds on a foundation already established by MIT researchers in 2007.
Bruce Belzowski, managing director of the Automotive Futures group at the University of Michigan Transportation Research Institute, called the paper "exciting" but said this particular vision would require a huge financial .
Embedding electric currents in roads is easier said than done, Belzowski said.
"You'd have to thousands of vehicles like this to make this worth it, " Belzowski said. "The cost is extraordinary. Tearing up roads and putting this type of technology in roads would be extremely expensive."
Still, Belzowski applauded the researchers' effort in this area and encouraged further exploration beyond the research and development phase.
"I'd never put anything past an engineer or group of engineers or researchers to maybe find something, " he said.
The electric car market is rapidly evolving. Tesla Motors has said its upcoming Model 3 will go more than 200 miles on a single charge. The Chevy Bolt has an advertised range of 238 miles before charging is required.
In Norway, a slew of has brought the sticker price for electric cars lower than, at times, that of their gas or diesel equivalents. Perks of owning one include no highway tolls, free ferry rides and waived sales taxes. Under the Obama administration. In April, as the most valuable car maker in the U.S.
But new federal policies could dramatically undercut the momentum of electric cars, Belzowski said.
By backing away from regulations and incentives established under Mr. Obama, President Trump could, industry analysts have warned.
"I have a feeling there's not going to be much of an incentive to move in that direction by the government, " Belzowski said. "Compared to China, which is giving out significant incentive to companies and buyers to try electric vehicles."who product mix what startup companies to invest in where startup folder windows 10 when management wants you out whose forest solution how much manager make when entrepreneurship is successful when engineering and administrative controls who to hire first startup what project launched the internet how far machine learning when project is not ready how much equipment for ice cream how much technology is used in schools how many technology be described as an element of ob why science communication is important how tech savvy are you interview answer where to buy clothes from manufacturer how much factory unlock iphone how much london trip cost from india where's device manager who design nursing care protocols where is gretchen from project runway what engineering has the least math which startup is best in india teachers day roadmap when can we travel which workers does rmt represent where to business listing where to find science articles how many science credits are required to graduate what development happens in the third trimester where product key windows 8 how design a logo why products fail in the market where to launch kayak near me what development did you find how much science diet to feed my dog whose project is manila international airport where is working solutions located how many entrepreneurs fail where to buy road map why solution is called homogeneous mixture where do production engineers work where is working solutions located whose product is 12 and sum is 7 how many design slots acnh why solutions must be standardized how entrepreneur works where to startup programs how many london bridges are there why design is important how equipment jackson michigan where boxing equipment why roadmaps are a waste of time when startup india launched how much technology changed over the time which solution is hypotonic why technology is bad products who test on animals what science is taught in 12th grade how company 401k match works why device drivers are important how much company worth whose products does ocado sell what engineering degree should i get who's are whose how teaching styles affect learning why business matters to god how farm equipment where to find entrepreneurs teaching where i'm from poem what product is dr pepper where human came from science where technology started when london was founded why product marketing who is the greatest entrepreneur which product roadmap who owns defi solutions how much technology should be used in the classroom how much startup capital for small business who system dynamics how many science bear quests are there where to solve word problems where's the science weapon on groundbreaker when london bridge is falling down where to find solutions which business development increases cash what solution is used for covid test where business administration can work where to products online where to business name registration where is temple from design star how many science bear quests are there when technology gets ahead of society which london airport to fly into how much engineering cost in india where technology came from how development affects environment who teaching resources where management system where entrepreneurial ideas come from how many technology are there in the world which entrepreneur is not intended in innovative where product key windows 8 when workers are aligned they tend to how much company stock should i own how many solutions are there to the system of equations where to watch science fell in love which solutions are isotonic whom would how many project management processes are there how long startup repair takes where is mgmt how to roadmap in jira why science is my favorite subject what start up expenses are deductible
