Another electric vehicle (EV) startup is touting “holy grail” charging technology.
The news from UK-based Nyobolt might just rise to the billing, as it promises 155 miles on a six-minute charge, with production slated to start in 2024.
Most EVs take much longer, sometimes even hours, to fully charge.
“With our unique technology we have … developed smaller battery packs that can deliver more power and charge in less time,” Nyobolt CEO Sai Shivareddy told BBC Top Gear.
The Nyobolt website doesn’t go into great detail about the tech inside the battery. The makers promise high power, a long life cycle, and improved safety to go along with the extremely fast charge time.
Lithium-ion batteries, common in EVs and a lot of other technology, have, in some cases, caught fire. Battery-makers are working on better alternatives, in part to reduce the explosion risk. Nyobolt experts claim that its battery has a “wider temperature performance.”
What’s more, it plans to put the tech to the test in fast fashion. Nyobolt has teamed with the UK’s Callum Design to create a sports car. The Nyobolt EV has the curves of a vintage roadster, but there’s no doubt it’s from the 21st century. Everything on the car is as high-tech as it gets.
After watching a video showcasing the car on Callum’s website, it wouldn’t be a surprise to learn the EV comes with a warp drive (maybe in the next generation).
Motor Authority reported that Nyobolt hasn’t released a production date for the sports car. But the battery tech is ready for “rapid scale-up” next year. The power pack has been tested with more than 2,000 fast-charge cycles with good performance, according to the Motor Authority report.
It’s more good news for the EV industry as it tries to match range and performance with gasoline-powered vehicles.
Nyobolt is considering plugging into the truck, bus, and luxury categories, as well, according to Motor Authority.
The sports car could be the first big test for the startup.
“Nyobolt’s technology allows this car to tick all the boxes,” Callum creative lead Aleck Jones told Top Gear.

“Now, had this breakthrough been announced by the MIT Department of Engineering, I’d feel a lot more confident.”
Left out the biggest step of all: engage connected Democrat donors.
“Perpetual motion, cold fusion, 100 mpg carburetors, the pill that turns water in your fuel tank to gas, magic batteries, climate change etc. all fraudulent crap that credulous fools not only believe, but harden their minds against reality to protect their false belief.”
All you have to do is claim the big oil companies stole the formula and you’re in like Flynn. The gullible fools will lap it up and repeat it.
A truth brought home to me nearly every day when I go out and see people with paper mask on their faces.
Sounds like recipe for an explosive fire. Fed
Thanks for doing the math.
Like I saiid elsewhere on the thread you most likely would have to upgrade everyone to three phase electric service to power charging.
Capacitors can charge that fast; batteries cannot.
Cheap at twice the price says Joe Biden.
I have long thought that Super Capacitors were a more promising tech for electric cars.
But they also have a nasty habit of catching fire.
Next up - batteries that give you 6 miles and only take 11 seconds to recharge - whatta deal!
What they’re announcing is not about the battery, but it is about “we’re ready to receive grants, guaranteed loans, government contracts, and any other sources of funds that don’t require much in the way of performance, and no responsibility to account for or pay back any of the funds”.
My sister has a Honda hybrid that she loves. She tells me she only has to fill it up once a month.
But for me they still have the weakness of battery longevity.
When the battery dies the car is essentially worthless.
There is also the added complexity of having an added electric engine-generator and the charging system.
The added weight is not much of a problem because it is a compact car but for larger vehicles the added weight becomes a problem.
155 miles on a (six-minute charge), with production slated to start in 2024.
Now if only the can fix the kboom and flames issue by 2024.
Fools bling another gold Lexus key.
Flames on a car? Why is that a problem?
Hotrods always had them painted on them a few years ago.
“ Hotrods always had them painted on them a few years ago.”
These flames are a lot more realistic.
If they really do have this great tech, there is NO WAY they did not apply for a series of patents.
Patent applications are published 18 months after the earliest filing date. Judging by how close they claim they are to production, it's a safe assumption those applications were filed more than 18 months ago. They will be accessible to anyone on the planet through any of the free patent databases. A name search for the company and/or the CEO/inventor should do it.
155 miles in a Tesla takes 53 kWh according to google. If the car is using the 800 volt standard, wattage equals EI or 53,000/800=I or 66 amps at 800 vokts for one hour. To cut this down to 6 minutes you would have to multiply the current by 10 to get 660 amps at 800 volts to get the same power. That’s one heck of a current draw. Engineers feel free to correct my math if I’m wrong.
Capacitors can’t store that level of charge for any reasonable length of time. They have the same energy density issues as batteries with the added attraction that they dump their maximum current in the beginning of their discharge. Think exploding wire. Having worked with high voltage capacitors in the past I can tell you that they are much more capable of instantly frying you than a battery.

Yes but not real ones EV’s are a rolling tome bomb.
“I wonder how much heat they have to remove for this. Even if it’s 99% efficient, it’s still generating nearly 50 kW of heat in the battery.”
50kw is not a large amount of heat spread over a ten plus square-foot area which would be the surface area of the cells themselves. Liquid cooling is more than capable of cooling that sized load even ten times larger. To put it into perspective a typical 4 cylinders turbo charged car has a net output of 350hp that is 260 kilowatts of output. At most a spark ignited direct injection engine is 40% efficient and only at 75% load at 100% kpad it’s well under 30%. So to produce 260kw in net output you have three times as much heat energy in play. With 70% of that as waste heat about half leaves as gases the other half is dumped into the cylinder walls. So 250+kw of heat is being transmitted to 4 cylinder walls that are 4 inches high and about the same diameter. The heat flux is in the tens of kw per square centimeter range. Liquid cooling takes the heat with ease keeping the walls at under 200F while 1800F+ gases are millimetres away. Tesla has semi packs that are liquid cooled that will.be charged at 3 megawatts or more with the megacharger which uses liquid cooled cables and plugs.
Anyone who has ever seen a ship come to port and go on shore power has already seen a megacharger port they took that design and scaled it down from 30 mw shore power to one tenth the size. Gen 4 supercharges already have a protocol for 1000&1200 VDC the connectors are already rated at 900 amps per the specs that is a megawatt when at 1200V. Batteries are the issue the charge standards have been worked out by competent engineers.
What people don’t realize is that a very small subset of gasoline users use a disproportionate amount of fuel they are called super users where 10% of drivers burn 30% of the fuel three times the average. The average driver drivers less than 40 miles round trip per day with 95% of all trips anywhere under 30 miles total.
The argument about the power grid falls apart when you remove that 10% hogging the fuel. At 40 miles per day a model S Tesla would use 10 kWh or equal to running a cloths dryer for a single hour or the AC unit for an hour extra hardly grid crashing. That is what 95% of all people drive per day or less.
Four commercial solar panels on the garage would make 10kWh on an average Texas day any day of the year including in Jan the shortest day of the year at 33N which is still ten plus hours of daylight. When not if electrics solve the charge time/ cycle life issue for commuter cars there is no equal economically.
A model 3 used would be 26 cents per mile with 25,000 miles on it till the end of its 120,000 mile warranty trash it at 120K it’s still half the price of a comparable sized car in the same luxury class. Compare a S60 Volvo which is within one inch in size in every dimension and within 200lbs in curb weight.
Look at the used prices for a 2021 with 25,000 or less miles. That Volvo will be 35,000+ vs 25,000 for the model 3. The Volvo in fuel cost alone at 30mpg and $2.50 fuel is triple the model three with 8 cents per kWh Texas retail power on a cents per mile basis.
A model three needs 180wh in the city a.c.on blast and 260wh per mile at 75 also a.c.on blast. Those are real world numbers from a model 3 rented in Houston from hertz. 180kWh per mile at 8 cents per kWh is like getting gas for under 70 cents per gallon. The capital cost of the vehicle is from day one ten thousand less.
Electrics win in the long run its not if it’s when for commuters the math makes sense even at 100 miles per day round trips even better if your employer has free charges for you to use mine does it would save me $3000+ per year in fuel costs even trashing the car the second the warranty life is over it’s still ten grand cheaper in sunk capex than the equal sized comparable luxury vehicle. With full self drive its a no brainer as a commuter car.
Your math is right. Generation four Tesla supercharger standards are 1000/1200 VDC at 900 amps with air cooled cables and plugs. The Tesla mega charger based off shore to ship power plugs is 3000 amps at 1200VDC using liquid cooled plugs and cables. For comparison when a cruise ship docks it has connectors for 30 megawatts also liquid cooled the Tesla Mega is a scaled down version of those plugs. In the EU they have 800V as standard with 900 amps as the max current using the CCS or the Tesla standard plugs. It’s type to think you can’t push a thousand amps through a 15mm wide cable your typical starter in a full sized truck is pushing 1200 amps in a thumb sized cable all be it for few seconds for continuous use air cooling is sufficient for 900 amps in a braided half dollar sized cable pair.
It’s all for nought for most driver’s. The fedgov keeps track of trips,commutes and drove length. The vast majority of trips are under 30 miles total per day. Why because most people live in high density city and suburban areas a disproportionate amount of fuel is used by ten percent of all drivers fully one third take those out and short range 200 mile vehicles make sense. The average commute is under 40 miles total per day with the two sigma past the average under 100 miles at the top end. Even at 100 miles per day that is only 25kWh per day. A dryer sized plug at 240 and 40 amps would add 25kWh in 2.6 hours. 25kWh per day is equal to running the avg home a.c.for 2.5 hours or a cloths dryer for the same time hardly grid crashing.
The difference in my home’s energy use from summer to winter is 3500kWh per month to 500. Peak use in August is 115kWh per day adding 10 more to that for the average 40 mile commute is a rounding error. Those numbers are for a full sized Model S the midsized model 3 would cover 40 miles with 8kWh or less even blasting the a.c.. I have seen in stop and go Houston traffic with Houston summer heat a.c.loads 90wh a mile due to regen and crawling speeds which is very little movement energy it was almost all a.c. Load at that point. Once you take out the small percentage of high gas users the rest of the population could easily be converted to electrics.
For road trips once or twice a year which is again what most people do especially city/suburban dwellers who make up 83% of the total population a rental car makes the most economic sense. If you fly for vacation you are already renting a car at the destination. There is a reason for the large number of daily low mileage trips we are a urban population dominated nation. For my own use a model 3 charged at my work for free is going to save me $3000+ per year in fuel, cost ten cents per mile less in sunk capital expense than the car it replaces even scraped at the warranty end point of 120,000 miles. Every mile past that point is more money in my pocket. I take road trips three or four times a year for that I’ll end up renting a Prius hybrid or a camery hybrid both will return 60mpg at 75mph and run 500+ to the tank. With an LLC you can rent either for $24 per day unlimited miles from enterprise,hertz or budget they all price match Corp rates. It’s not worth the sunk capex to own either of those long distance cars when I need 100+ miles of range less than four times per year. Given than the model 3 will save me $3000+ in fuel it’s a net gain to rent the road trip vehicle even at 7 day rentals four times per year still over two grand in the black. My daily commute is 105 miles round trip two sigma past the average commute with 325 miles of range on a M3 when charged at the job location will never need to charge at my house leave at 100% drive 53 miles home, come the 52 back with 55% in the pack the L2 charger will have to back to 100% in 2 hours well before lunch time. It’s like getting a free gas card from work for personal use weekend local trips of another 100 miles would still leave me enough to come back Monday morning and charge back up on the company dime. 53+100+52 leaves over 100 left of comfort range even after weekending around.
