One of the world's major EV charging standards has released its 3.0 specification, harmonizing with China's GB/T plug and using liquid-cooling to deliver monster charging rates more than double what Tesla's V3 Supercharger is currently doing.

CHAdeMO chargers currently serve as many as 44% of global fast-charge-capable EVs, although this includes Tesla vehicles, which can connect to them with an adapter, and the figures are from 2018. Either way, at least three quarters of a million cars globally have CHAdeMO fast charge sockets and more are compatible with the standard.

Under the new 3.0 standard just published, which uses the working name ChaoJi, charging rates of over half a megawatt are supported, with current up to 600 A. The liquid-cooled plugs and cables will be significantly chunkier than the current versions, but will be backwards-compatible with existing CHAdeMO, GB/T and possibly even CCS standards.

This does not mean CHAdeMO chargers will all be capable of 500-kW blast-charging. Over 50 companies worldwide manufacture according to this standard and, while following the standards, they'll each build chargers according to their own use cases. The CHAdeMO 2.0 standard allows charging up to 400 kW, for example, but there are still plenty of sad little 50-kW chargers around, and in some places you're lucky if you can find a 100-kW plug.

Indeed, it'd be a mighty vehicle that could take that much energy at once, something like the barely believable Piech Mark Zero perhaps?

Even with a two or three charger set up these would need to rewired direct to the grid - even commercial premises seldom provide this sort of power capability. Pete

200 amps at 220/240AC is pretty much the biggest residential service. So this would more than max that out. But this seems designed only for gas-station-equivalent experience. 100-kwh battery pack would be completely charged (ignoring ramping issues) in 12 minutes.

Thes will go well with super-capacitor home charging ports.

There is no limit to the charging ability of a residence or station if a storage capacitance unit were installed. It would be turned on some time before the charging to store up sufficient energy to charge at whatever required high rate was necessary. In other words, it would act as a power unit in place of the power line to enable the conventional power system to be used without any necessary adaptation to the present power line system.

Why the rush? Many sources say lithium batteries will last longer if they're charged slowly. I'd prefer intelligent charging, where a vehicle learns your habits (i.e. 40 mile commute to work in the a.m., 52 miles with errands on the p.m. commute home) with the driver uploading planned side trips, then the car figures out just how fast it needs to charge and pulls no more than necessary to finish with a margin of an hour or so to spare. Better for the battery pack and less stress on the grid.

Very cool! 500kW of juicy charging goodness. Yum, yum! I wonder if these will be limited to charge centers directly next to electrical Substations... Now to get a battery set which will handle it. (No, these aren't for home charging. )

Enough storage capacitance would be a lot. You're talking the equivalent of 7-8 tesla power wall units, each with 10-15x the discharge rate of an actual powerwall. And supercapacitors are typically on the order of 10x or more mass/volume for the same energy storage, so that would be pretty much your whole basement or a good-sized outbuilding for a commercial installation. (I'm assuming for the moment that cost drops.)

Half a megawatt.. ok.. it would need it's own sub station connected to 11 or of multiple chargers a 33 kv feeder substation.. where not talking about tapping into the local 415 3 phase this would require digging up a lot of road to install a cable the diameter of a beer can.

AND WOT, IN THE NAME OF E-FFICIENCY (etc), DOTH HAPPEN TO YE 'WASTE' HEAT ? ? ?

It's good to know there will be more sophisticated EV owners/users than me: I rarely use the charge rate over 6A (AC, single phase) overnight. The math says I lose about 0.3% of juice in the wires. What about this beauty?
