Comment on Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging

Imo the way things stand things are already good enough as they are.
we don’t need to double battery capacity/distance or even charging speeds, it’s a massive waste of resources that won’t benefit the vast majority of people.
from quick google
Every day, there are some 70 Million (M) worldwide driving trips. The average trip duration globally is 15 minutes long. The average trip distance globally is 15 Kilometers / 9.3 miles. The average speed globally is 30 km/h (or) 18.6 mph
so even if you have a 200km worst case scenario range on your EV, unless you are one of those people that are on the road a lot, it literally covers like 99% of your car usage.
Hyundai EVs charge with 350Kw, to 80% in like 15m which is perfectly fine for a longer roadtrip imo. I used to travel 200kms every two weeks and in most cases I took a rest half way through the 2 hour trip anyway to stretch.
if you are one of those guys that will come on and say you drive 500+kms every day and BEV is just unacceptable for you, well guess what, just get a fucking Hydrogen EV, pretty sure those can get up to 1000km ranges already which is more than my Diesel Hyundai.
Average trip duration is not a great metric because they measure a trip as going from point A to point B. That’s great, but then I do six trips a day in errands.
Total miles per day is the metric to use. On average, in America, it’s 37 miles.
That is to say, EV cars would work for many people. But to reach the majority we need these advancements.
why? you literally say 37 miles, that means it’s already good enough for the majority.
Because we’re talking averages. People don’t buy a car to go an average number of miles. People buy a car to cover the maximum number of miles that they would go.
Maybe I average 37 miles a day. But four of those trips are 8-hour drives to see my in-laws. I’m not doing that in my Nissan leaf.
I’m lucky enough to have two cars. My Nissan leaf which I use for everyday driving, and an ICE for the in-law trips and my spouse’s driving. If there were a vehicle with extended range, like 300 mi, and a very quick charge, I would get rid of the ICE. Until then, 50% of my cars are not EV.
people go cars to go places 90%+ of those trips is below 200km
Averages are useless. It does not matter if my car is fine most of the time, I’m not going to have a second car for when it is difficult or impossible.
Hydrogen is the other tech which makes quick refuelling possible, but there are not yet enough hydrogen refuelling stations to make them feasible for most drivers. And we don’t yet know if leaks can be controlled enough to make hydrogen a net positive for consumer applications.
Averages are useless. It does not matter if my car is fine most of the time
so what, you would want to triple your battery capacity because once a year you might need it?
Where did once a year come from? I can’t reach any of my family without stopping to charge most (currently affordable) EVs. We only bought a car because it was getting more expensive to rent them when needed, we’re not going to pay twice over.
so that’s what 150+ 200+ km?
is it unfathomable for you to take a 15 minute break during a trip like that?
Have you rented a car for a week? It’s prohibitedly expensive for most people, especially if it needs to be big enough for the family and a week vacation. I’m considering getting an EV, but it’s only because we’ll have my wife’s gas powered SUV to use for our longer trips, which are 1-4 times a year. That not an unusual need, and one that make exclusive EVs a no-go for a lot of people. Hybrids are an option of course.
it’s not more expensive than owning a second car that’s for fucking sure. I can rent an RV for less than just the typical maintaince cost of a second car
I still don’t understand why people need ultra distance in EVs. If I drove as much as often as the “I need a million mile range” crew I’d take a good, long look at my life and what was wrong with it.
I mean, it could be part of the job they do, whatever, but people vastly overestimate what they actually need from a vehicle.
If my commute distance was as long as some of these people claim, I’d do any number of things to change that.
there is stuff other than commute, for example a friend of mine works as a mechanic for agricultural machinery.
so there are days where he goes 400km one way to go do repairs on a piece of equipment.
Of course he is an exception to the rule just wanted to point out that there are jobs where you actually have to drive more than a BEVs range in a day.

Faster charging means a lower chance of all the chargers are in use at the service stations en-route. Currently if you’re in need of a charge you’ll have to wait for the others cars to get charged and then you still have the 20+ minute wait for your own car. That’s going to put a lot of folks off owning an EV. Coupled with the fact the EV uptake is growing a lot faster than the charging infrastructure to support it. Faster charging has a lot of benefits.

except, the vast majority of your trips are from your home to some place and back, you charge at home and the range is more than enough to cover 90+% of your trips.
rather than focusing on super chargers (which we also need along high ways) we need to focus on smaller lvl 2 chargers at places where they make sense, apartment complexes, offices, to enable BEV use for people who don’t own a home with their own garage.

This assumes everyone can have a charger at home. A large portion of people can’t. Apartments, associated spaces, on-road parking… a lot of people need public chargers.

we can build out charging infrastructure for apartments and offices
