A few large EV charging tales simply popped up throughout the globe from the US. From Japan, we’ve bought information of a wi-fi EV charging challenge within the “good metropolis” Kashiwa-no-ha that would carry wi-fi charging to the following degree. Then, from China, we’ve bought information of Li Auto’s subsequent big automobile, the Li Mega, and its ridiculously excessive charging charges.
Helpful Wi-fi EV Charging in Japan
Wi-fi EV charging was little greater than a science challenge or futurist fantasy a decade in the past. Debates about the way forward for the know-how usually included the idea that wi-fi charging would all the time be fairly an inefficient, low-power charging choice — and the query was whether or not wi-fi charging would have any function within the EV future or not. In any case, how helpful is 6 kW wi-fi charging?
My, how the tech has modified! Wi-fi EV charging has, reasonably quietly, gotten sooner and sooner and sooner, and an increasing number of environment friendly. We’re now on the level the place the “good metropolis” Kashiwa-no-ha (close to Tokyo) is putting in wi-fi EV charging infrastructure underneath roads at fashionable intersections in order that EV drivers will be capable of cost up routinely when they’re out and about sitting at pink lights. And these are actually quick EV chargers.
Effectively, we’re not at widespread deployment but, because it’s nonetheless early days for this probably aggressive model of the tech. Researchers on the College of Tokyo and College of Chiba in addition to employees from 9 supporting companies (together with tire big Bridgestone) are engaged on this take a look at challenge collectively. The Japanese Ministry of Transportation can be concerned. Presumably, it will result in large-scale business deployment in Tokyo and past.
The massive stat now we have is: “10 seconds of passing over the coils gives roughly 1 km of autonomy.” Doing the short math, 6 km per minute means 60 km can be added in simply 10 minutes sitting above certainly one of these superfast EV wi-fi chargers. Reportedly, the max charging charge is round 150 kW, which is as excessive as the unique Tesla Superchargers!
Comfort is a large issue for a lot of drivers, and whereas residence charging is tremendous handy when you could have that choice, even that’s not as handy as getting charged up automagically when you are out and about doing all of your regular errands. Keep tuned for the following episode of “Will EV wi-fi charging play a giant function in the way forward for automobiles?” Increasingly so, it seems to be like the reply is sure.
Tremendous-Duper-Quick Charging in China
When you’re not going wi-fi, the following neatest thing so far as comfort goes is what one single electrical vehicle can now do — super-duper-fast EV charging. I’m speaking in regards to the coming Li Mega, a protracted, massive, glitzy electrical automobile from Li Auto that may cost as much as 552 kW. It’s not simply the max cost charge that’s bonkers, although. In keeping with the corporate, even when the battery is charged as much as 80%, it might probably pull in 315 kW of energy! That’s loopy.
In simply 11 minutes (and two seconds), the Li Mega can go from 6% state of cost to 80% state of cost (SOC).
The Li Mega’s phenomenal 5C cost charge is because of the CATL Qilin battery it makes use of. “If we oversimplify, the 5C cost charge says what number of occasions the battery may be charged in a single hour. On this case, 5 occasions, so in concept, you cost the complete battery in 12 minutes. In different phrases, 5C means ‘5 occasions the capability,’ so if in case you have, for instance, a 1000 mAh battery, you’ll be able to cost it with a 5000 mA present,” CarNewsChina summarizes. “When you’ve got a 4C battery, it may be charged 4 occasions in a single hour, so having a full battery would take quarter-hour.”
Right here’s a screenshot of the assorted charging specs and speeds of the Li Mega:
Wild, isn’t it? We’re in fuel tank refueling territory with this. The important thing distinction is that gasoline is pungent, very dangerous to human well being, and preparing for retirement.
The Li Mega, total, is kind of … particular, as Jo Borras and I mentioned on the latest EV Obsession present. It is vitally massive (like all Li Auto automobiles), very lengthy (wanting a bit warped even), and appears like a mixture of a Tesla Mannequin X and a Tesla Cybertruck. We dubbed it the Tesla Cybervan in consequence, or principally simply mentioned it seems to be like what a “Tesla Cybervan” could possibly be. What do you suppose — does this MPV from the premier electrical land yacht firm in China look Tesla worthy?
I believe we are able to safely say it prices a lot sooner than any Tesla for the foreseeable future.

Right here at CleanTechnica, we applied a restricted paywall for some time, but it surely all the time felt mistaken — and it was all the time powerful to determine what we must always put behind there.
