Hybrid and even all-electric sports cars have become the rage as of late, but how many of them can recharge their lithium-ion battery in as little time as a pit stop at the gas station? Meet Finland's electric RaceAbout, an all-electric sports car that has its sights set on the $10 million Progressive Automotive X-Prize, according to Inhabitat.
The four-wheel drive RaceAbout features a 124-mile (200-km) range and can fully charge in just 10 minutes. Its chassis also weighs half as much as similar-sized cars, in part because the direct-drive electric motor eliminates heavy gearboxes. The vehicle also incorporated other lightweight materials and technologies.
RaceAbout came out of the Helsinki Metropolia University of Applied Sciences, but also received help from many Finnish companies. It's just one of 44 teams scheduled to compete in a "shakedown stage" of the X-Prize at the Michigan International Speedway this April.
A final winner will emerge in September for having developed the best production-capable electric vehicle that exceeds 100 MPG. But anyone tired of just being a spectator can already place orders for electric sports cars that get to 60 MPH in five seconds.
More FACTS please gentlemen.
Apaprently reading further (if you believe some of this stuff) ....
" And although battery technology is constantly improving, the team still needs to hook the vehicle to a power source capable of generating 350kW in order to facilitate a 10 minute recharge – that’s enough electricity to power roughly 20 houses at once. "
So are these fine gentlemen doing exactly that to acheive this now ? Very VAGUE.
I have a electric car that can be charged in .0001 sec, but it needs 1.21 GigaWatts of power; ohh you want to charge it using 1.5kW AC outlet, that will take 33.33333 hours.
PopSci you are publishing usless stuff here and are getting on my last nerves. The Title suggest 10min charge time, but all you write about is the X-prize and the range of the vehicle. No mention how the 10min charge time is achived; or maybe how much the vehicle will cost if it ever goes into production.
Failed to mention is how long will the battery last with such high intensity charge rate. It will be a toy for the rich only if the cycle of battery is miserable 200x vs normal cycle of 2,000x.
O Please, everyone is missing the point, obviously first generation electric components will be improved over time like anything in life, the motors is already super reliable,
and the un-sophisticated drivesystem is outstanding, so what if you get 200 cycle time. Hands down it will improve period. Goes without saying!
It's an excellent start!
so what if you need a big power supply, the point is that it can be done, and it will be improved!
And that when E-vehicles take over the world, and they will, the infrastructure should think and plan ahead for it's arrival.
No more no less.
Service stations have underground tanks, to refuel cars in a few minutes.
Why not battery banks, to recharge cars in a few minutes?
RAT and Tygrys' comments are akin to service stations depending on a thin pipe from the refinery to supply gasoline ...
Unfortunately no, it requires something with a little more kick - plutonium......... This sucker's electrical. But I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need.....Marty, I'm sorry. But the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning Unfortunately, you never know when or where it's ever gonna strike. haha
Electrix, correct EV technology will improve but how much time do we give them: 3yrs, 5, 10 so that you can charge the car with 110V AC in 10 minutes? And don't forget that in time everything will improve, including gasoline engines. I'm an EE and I'm up for clean & revolutionary technology, but EV tech needs to improve much faster than gasoline tech or other energy tech.
And when can we buy an mid-size EV sedan at $15000 WITHOUT federal & state tax credits?
350 kW for 10 minutes. Let's say the batts are 600 volts.
350000/600=583 amps! What size of cables do you need for 583 amps? What kind of connector? Sounds like a recipe for major fireworks if a connector gets dirty or worn a bit. Even the magnetic fields from the wiring will be significant. How do you keep the battery from getting too hot? They must be doing a battery swap, not a recharge.
If you are an EE then you must know ohms law. You are suggesting a 10 minute charge on 110 volts.
Ok the battery needs to store at least 30 kWh. After all you need a certain amount of horsepower and a certain amount of time/distance. If you want to deliver 30 kWh in one hour, you need a 30 kW supply. If you want to do it in 10 minutes multiply by 6. 180 kW supply. Now divide that by volts (110) and you have 1,636 amps. Your home outlet might deliver 16 amps at 110 volts. Are you going to plug into 100 outlets? Are you going to make a receptacle that can deliver 100 times the current of our home receptacle? How about the transformer that powers your house, are you going to ask the power company to take down your 15 kva unit and replace it with one more than 10 times larger.
Come on EE, show us the math behind your assertion.
It's progress not perfection...........and I think it is great! Now if someone can produce an affordable daily driver that's a different story.
I was asking, not confirming, how much time in research we will give the engineers to provide technology to charge the batteries with 110V AC in 10min. As you have done the calculations, it seems that it will be almost impossible to charge in 10min using 110V AC.
Now perhaps a charging station can have thick enough cables to deliver 1636 Amps; that way you just pull in, charge for 10min, and pull out. Or perhaps you can have 2 banks of batteries. Then you charge each bank independently with 818Amps for 10min, using 2 independent cables. Or perhaps you break apart into 10 Banks, and have connector with 10 cables and now you are down to 163.6Amps per cable. Once you are done charging, you connect a some sort of shorting plug where it connects all the 10 banks into a Single 30kWh bank. If 163.6Amps is still too much, then you can divide into more banks, or increase time to 20min (which is still reasonable).
In the .0001sec charge with 1.21 GigaWatts (& 1.5kW, 33.33333hrs) comments I was being sarcastic; in case you didn't notice.
