This Japanese metropolis is piloting EV wi-fi charging at site visitors lights


A metropolis close to Tokyo is the primary in Japan to check wi-fi charging for EVs – and the chargers are in entrance of site visitors lights.

Wi-fi charging for EVs at site visitors lights

The pilot is being run in Kashiwa-no-ha Sensible Metropolis by the Universities of Tokyo and Chiba, together with 9 corporations, together with tire maker Bridgestone and auto elements makers NSK and Denso. (Kashiwa Sensible Metropolis is known as that as a result of it’s a mannequin metropolis for clever transport system experiments.)

The College of Tokyo created the in-motion energy provide system, and now the researchers need to check its sturdiness and skill to persistently cost for EVs and plug-in hybrids driving over it.

Precast charging coils are embedded into the street’s floor in entrance of site visitors lights. A present solely passes by way of the wi-fi chargers when a car is detected. EVs and PHEVs which have particular units put in close to the tires to obtain the electrical energy get a cost after they decelerate – 10 seconds of rolling over the coils gives about 1 km (0.6 miles) of vary.

The College of Tokyo says the demonstration experiment will probably be performed from October to March 10 underneath the path of the Ministry of Transport.

Electrek’s Take

Will this pilot flip sluggish site visitors and stopping at a pink mild into one thing EV drivers are comfortable about?

A minute = 6 km of vary. Now, that’s not precisely going to do a lot for somebody on a street journey, but when wi-fi chargers have been put in at each site visitors mild, this could possibly be useful for EV drivers who drive domestically rather a lot.

Whereas dwelling EV chargers are, IMHO, the easiest way to cost up, not everybody has that possibility, and condominium dwelling is the norm within the Tokyo metropolitan space. So if somebody who lived in Kashiwa often zipped across the metropolis in a small, mild EV, then I might see how being wirelessly charged at stoplights could possibly be useful. At any price, isn’t the purpose of pilots to see whether or not an concept will work IRL? I’m intrigued to see their findings.

What do you concentrate on the Kashiwa wi-fi charging experiment? Tell us within the feedback beneath.
