好奇＆回歸主題一下...
有辦法求證這則新聞嗎？
若這是真的... 絕對是電動車的超級重大的突破！  |
原網頁就有人寫了,不過這還是很樂觀的估計,以鵝看來充電站充一台車須要的電力至少是1500KW起跳的(1.5MW----恐怕得拉161KV的饋線才推得動吧  )....

From what I've been able to dig up, the battery pack holds about 115 kWh.
In any case, your typical EV these days goes about 4 kWh/mile, which matches up nicely with their 375 mile trip.
So if you want to fill the car with 100 kWh in 6 minutes, you'd need about 1000 kW (ignoring charging losses).
Your typical house in the USA has 240V service with a main panel size ranging between 100A-200A - or 24-48 kW. There is no way you're charging this battery in a short amount of time at home unless you use some sort of buffer.
Your typical EV today uses a Level 2 J1772 EVSE - of which the J1772 specification will handle up to 240V AC at 80A or 19 kW. But the first mass produced EVs on the market (the Leaf/Volt) will only be able to charge at 3.3 kW or so using that standard.
The Tesla Roadster can charge at up to 19 kW, but still uses a slightly different plug (Tesla came before the J1772 standard, but existing Roadsters are expected to be converted over).
"Gas" stations to sustain Level 3 charging (meaning anything that spits out high current DC) are currently being deployed with chargers that will push out a max of 50 kW or so. The Leaf will be the first car to use those chargers and can charge it's 24 kW pack to 80% in 20-30 minutes.
I suspect that some sort of local battery buffer will be needed in most locations to support 1000 kW chargers - or you'll need to be very close to electrical substations and transmission lines.
