This is not what we need. We need more chargers in convenient locations. There are multiple popular highway rest stops in my region that do not have DCFC. In an ideal world, apps like ABRP would be unnecessary for road trips. If I make a bathroom stop, I should also be able to charge. Don’t stop to charge, charge when you stop.
We need both.
In ideal conditions, a 300 kW charger can deliver 50 kWh in 10 minutes. That’s mostly fine, but on a road trip still involves 10 minutes of charging every 2 hours, much more frequently than the typical restroom break or snack break.
And if people are going to be leaving their cars to do other stuff while charging, there need to be a lot of stalls so that there are open spots at popular rest stops. Delivering high power to each stall is helpful to speed them to idle/trickle, so that the overall circuit for the whole set of multiple chargers can efficiently direct the power to where it’s needed most.
The current status quo is about 20 minutes every 3 hours (in a model 3), which is a perfect travel pace IMO. People consistently underestimate how long they spend stopped on road trips. The EV adds about 4 minutes per hour for each hour past 3. It’s really not a big deal.
What is a bigger deal is when charger locations are poorly located, requiring inefficient stopping schedules.
a perfect travel pace IMO
You’re obviously free to do road trips the way you want to do them, and 20 minutes every 3 hours is the kind of thing I can do with my kids, but on trips I’m doing without the kids I’d prefer the option of stopping for less than 10 minutes every 3 hours. I have a 500 mile trip planned this summer and I’m basically gonna throw in an overnight hotel stay in part to make it easier to top off at a charger while we sleep, but if I still had a gasoline vehicle I probably would just be driving straight through by leaving early in the morning, rather than doing an evening drive starting the night before.
And I’m with you on the charger locations being a bigger inconvenience. It takes a lot more planning/flexibility (ABRP and a few backup plans in case certain chargers are occupied or out of service or slower than advertised when I get there). But still, I’d like to see improvement in the driver experience for all of it.
I say we need both.
People who go long distances need to stop to charge.
Kempower unveiled its new charger […] that can dispense 1.2 mW
At 1.2 mW, my electric car would need roughly 8.5 millenia to charge. At its average consumption, every kilometer driven would require 35 years of recharging. Like, I don’t want to sound too picky, but I guess I’d rather walk tbh.
Almost no one can keep kW and kWh straight, why would you think they could understand MW?
We should have stuck with MJ and MJ/s. No need to get W or h involved.
kW and kWh helps understanding charging speed/capacity better than MJ and MJ/s.
Btw. 1 MJ/s = 1 MW, but you surely know that.
Are they trying to make viable EV pit stops for racing?
I guess this would make ridiculously sized batteries for semis viable. Though I’d rather pivot back to freight trains than put that much weight on our roads.
Semis are responsible for most of the road repair budget in the US. There’s a cheaper way. (If the government didn’t pick up the tab for all this semi road damage.)

No, I think you’re jumping to an invalid conclusion here.
Yes, heavy vehicles cause much more wear and tear on roads than light vehicles do. But a lot of road damage is caused by stuff other than vehicles driving normally on top.
Most road surface repair is necessitated by weather: freezing and thawing creating cracks, physical scraping from snow plows. Plus there are issues caused by soil erosion, tree roots pushing on stuff, other wear and tear caused by stuff falling or blowing on the road.
You can see it in places that have dedicated bike lanes, narrow residential streets where heavy vehicles simply can’t drive, etc. When the pavement gets old, potholes and other cracks still form, even with no heavy vehicle ever driving over it.
Those chargers are useful for the next generation consumer EVs.

Alas, the BYD ones will be hard to get by in the USA. Unless some American EV manufacturers can keep up with the Chinese EV manufacturers, ICE cars will be “recharged” faster than EVs - mission accomplished, I guess.
Most cars and drivers don’t need this. And most chargers won’t be upgraded anyway.
I beg to differ.
Charging time is still a strong deterrent for a lot of people considering EV instead of ICE vehicles.
I’d be happy to have such capabilities available, because I often charge my EV away from home and it’d be nice to have it done even faster, although I’m quite ok with 10-80% (equalling close to 300 km/190 miles) in around 20 minutes.Most people don’t drive 500 miles regularly. Most people can wait 15 minutes to charge and then go on their way. Most existing chargers are good enough and won’t be upgraded any time soon.
