BYD Unveils New Super-Charging EV Tech With Peak Speeds of 1,000 kW (yahoo.com) 25
fahrbot-bot shares a report from Reuters: BYD on Monday unveiled a new platform for electric vehicles (EVs) that it said could charge EVs as quickly as it takes to pump gas and announced for the first time that it would build a charging network across China. The so-called "super e-platform" will be capable of peak charging speeds of 1,000 kilowatts (kW), enabling cars that use it to travel 400 km (249 miles) on a 5-minute charge, founder Wang Chuanfu said at an event livestreamed from the company's Shenzhen headquarters.
Charging speeds of 1,000 kW would be twice as fast as Tesla's superchargers whose latest version offers up to 500 kw charging speeds. The new charging architecture will be initially available in two new EVs -- Han L sedan and Tang L SUV priced from 270,000 yuan ($37,328.91) and BYD said it would build over 4,000 ultra-fast charging piles, or units, across China to match the new platform. "In order to completely solve our user's charging anxiety, we have been pursuing a goal to make the charging time of electric vehicles as short as the refuelling time of petrol vehicles," Wang said.
"This is the first time in the industry that the unit of megawatt (charge) has been achieved on charging power," he said.

1,000 kW? That's a megawatt. Use the word. (that is rather impressive, actually)
It is, but you won't just be plunking those down without the participation of your local electric utility.

Sorry, but I'm an American. How many horse powers per hour/second/minutes is that?
It doesn't matter where you went to school. All of us will need to learn about electrical charging soon.
Using 1 megawatt to charge the battery for five minutes is just how fast the charging is happening. The question you're asking is about as relevant as asking how many gallons per minute is a gas pump filling your car. If the gas pump at the Chevron station can fill my gas tank twice as fast as the pump at Costco, does that make it better?
Actually, for EVs, sometimes the difference between a 5 minute ch

A thousand amps at a thousand volts? That's a serious conductor. Are they using solid bus bars instead of cables?

You are a few decades out of the loop.
The Chinese stealth fighters beat the F22 and F35 in every thinkable regard. Except for vertical take off an landing, of course.
And regarding the Russians: their jets are not bad. Just expensive and even more expensive in maintenance. Some of them have not even 100 flight hours until the whole engine needs to be replaced. That is basically a knock out criterium.
If you build the charger, battery tech will come? (Score:2)
My car is rates to 250kw of charging, but it quickly drops off as the batteries heat. I suppose they could put a lot more effort into heating the batteries before arriving at a charger and then a lot more effort into cooling the batteries while charging. That means extra cost, complication, and weight, lowering efficiency. Or they could just kill battery longevity. Or they could just be making ultra fast chargers that will be underutilized while waiting for battery tech to catch up.

Battery lifespan (Score:2)
You can only push so much current into a battery without destroying it and the higher the current, the faster they degrade.
Not to mention modern fast chargers are 1000v and at the limit of how much current you can push through their wires and connectors. To hit 1 megawatt you either need even higher voltages, or higher current- both of which require stouter cables and connectors. Not to mention the added safety risks that come with such systems.
Is it doable? Sure. Do I think current battery designs can hand
