I used a supercharger for a car, it took 45 minutes to go from 40% to 90%. That was charging at 440 volts and 96 amps. I would think a truck battery would have a larger battery and hence take longer to charge.

Lol, why are you putting hydrogen in houses??

To use hydrogen in passenger vehicles it would probably need to be stored chemically. Then there is a whole new set of problems to solve.
Baw hydrogen is the most energy dense liquid fuel (thats not an opinion thats a fact).
And the real kicker is that hydrogen fuel cells extract about twice as much energy from hydrogen as hydrogen ICE. So if we ever do use hydrogen to power passenger vehicles, it will be used as a battery to power electric motors. Combustion is just not efficient.

Maybe big ships and perhaps trucks and trains can take advantage of hydrogen as well, but you severely underestimate just how much infrastructure would have to be built to support hydrogen powered passenger vehicles. We already have the infrastructure for EVs.
But the fact of the matter is that pertinent plants, vehicles, and existing infrastructure can and will be modified and it's just a matter of time.

Find a mix of 10 single people, male and women, and I guarantee you that every one of them has put something in the truck bed more than once a year.
Is this excluding people who regularly keep something back there at all times? Tools? Spare tire? Etc.

You’re suggesting a ten person survey to refute data produced by actual market research companies that’s backed up by manufacturers.

And now you’re going down the let’s manipulate it so that if you keep a spare tire back there it counts.
I’m just asking what they factored into the survey.
Like I said. There’s absolutely no way 35% of people that own a truck have put something in the end one time a year.

Does it?
What about the ease of loading and unloading.
You could probably fit 10 items in a truck bed and those same 10 in a trunk. But you could go into the truck and grab anyone you want. You’d have to unload some from a trunk to get to others.

The best reason to not own a truck is you don’t get hit up regularly to haul shite by folks who don’t own a truck
For me owning a pickup is like owning a boat, it is better to know someone with one than own one yourself. I own a boat so I am a special kinda stupid too.
I think the 35% is overblown without some caveats since it is similar to saying only 35% of people use the trunk or cargo portion of their car/SUV once a year. I will say it might be pretty accurate for people using their cargo bed of a truck for things that wouldn't fit or they wouldn't want in a trunk or cargo area. There are a lot of P/Us in my neighborhood but most people just commute in them and most of them don't do any work around the house or in the yard to need a P/U. I personally don't like driving a P/U so I use a trailer behind an SUV it is a bit of a PITA but it is so infrequent I still prefer it because I would still prefer an SUV even as a third vehicle.
While I don't get the love of pickups and think they are poor value most of the time I understand it is no more silly than having a daily driver that can top 200mph. As for EVs I think for over 80% of people (who currently have a place to locate a charger at their residence) and 98% of their driving an EV is a better choice. The US has a deep-seated car culture that dislikes change and also people that won't do something even if it is better for them if they feel forced to do it.

I'm just the opposite. I had a car once for a year and I hated it.
I really never had the need for a SUV. We just never needed the seating capacity and I'd much rather have an open air bed at my disposal than extra seats and a cargo area.
My wife would probably do fine in an EV. She parks in a garage and mostly just drives around town. I don't see much reason to run out and get one though. She just bought another car actually and decided she wanted another Honda.

Man what the frick are you talking about?
If the stuff can go in a trunk then it's dumb to say people "use" their truck beds. They only use the bed because they don't have a trunk. If you count those use cases then your data is worthless. Such data would serve no purpose in a discussion about whether people use or need the capabilities of a truck. Using such data has only one purpose, and that is to purposely skew results to tell you what you want to hear.
And fwiw I drive a truck and I haul shite in the bed and in a trailer regularly.

I’m not using any data. I’m saying that writer is doing this:

The article specifically said:
35% of people only “putt something in the bed” once or less a year. I’m saying that’s bullshite.

I completely get why a lot of people like trucks as a DD. For me, they are too large, too slow, and don't handle/brake very well. It is just a personal preference. Our primary need for an SUV outside of hauling larger things is hauling our dogs which would be less than ideal in a truck and basically impossible in our cars.
I actually thought my wife might be interested in an EV next time around because the vast majority of her driving is commuting, any road trips and we take the SUV. When I broached the subject a month or so ago she just responded sure when one sounds better than mine. It became a non-discussion at that point since there are not a whole lot of ICE engines that sound better than her car. It seems we are going down swinging with ICE vehicles despite me having a bit of an itch for one.

The step after that will be a bolt a lightning that can charge it instantaneously and take you back to the future.
quote:I think it would be negligible, at least through a certain range of SoC (like 10-80%). DC fast charge curves start slow, speed up, then slow down again at the top to manage heat and cell degradation. As I understand, the cells can handle faster charge rates in the middle of the range, but the main limitation is the charge cabling. I guess 500 amps is about the max we want to go due to cable size, so the only way to increase wattage is to step up the voltage. At the same 500 amps, 400v charging is 200kW and 800v is 400kW.
But at such high voltages and cycling won’t that shorten battery life.
So yeah while the same amps are going into the car, each individual cell will be taking in twice the current assuming the same size pack (same number of cells). If it takes 100 cells in series to get to 400v and 200 in series to get 800v, then the 400v system would have 2 parallel stacks of 100. So if 10 amps are coming in from the charger, that would get divided in the 400v system with 5 amps going through each cell, while in the 800v system the full 10 amps would go through every cell. But again, I think these higher charge rates have a negligible impact on battery degradation through a certain range of SoC and temps.

That wasn't what he was talking about; but the garage, where you park your vehicle of any kind is where you would park your hydrogen vehicle. It would be filled up at essentially a gas station, but with hydrogen. But I do agree that a lot of the currently developed (and not released) hydrogen vehicles will/are being used for commercial use, at least initially.

Some truth in that, but it would be ultimately cheaper than gas eventually and cheaper to produce and result in totally carbon free emissions (which is the ultimate goal with all of this, particularly when it comes to airplanes and long haul trucks), and the application for hydrogen combustion powertrains are more being researched for long haul trucks and airplanes (and yes personal vehicles as well).

Combustion has never super been efficient, you can only get -50% efficiency in the best gas ICE.

I wouldn't say DOA, you can take my word or not, but domestic and international O&G and Energy companies as well as National Departments of Energy globally, are all researching this now (many past R&D at this point), and have been doing so for the last decade and honestly more. Fuel cell drop ins for batteries definitely have an extremely large already existing market for fuel cells to replace electric batteries in existing vehicles.
The infrastructure for EV's is there but it was not there even 10-15 years ago, not to mention It is still currently very small, using existing roadways and slow chargers for home use or, if you are lucky, in a larger city parking lot. They are just now looking into road taxes for EV use. I am not anti EV, I just don't think the lay person understands the phenomenal implications of hydrogen being used in EV as well as hydrogen on it's own.
If the goal is to have a totally clean emission free system in place, EV's are still powered by a predominantly coal grid, and until we change out laws on nuclear power plants which is not changing any time soon, we are where we are. A LOT of work is being done for hydrogen to become a cheap viable fuel source, and is at this time it is the cleanest "legal" source available with a lot of aforementioned R&D being put in to effectuating this goal.

Don’t get me wrong. I don’t dislike Hydrogen and it has a ton of specific uses that I think will get some traction in the highly centralized areas, but distribution will always be its problem.
The PE, VC bros I work for are all looking at it but there’s no decent market case for real growth right now. A ton more money going into storage tech right now.

quote:That is approaching the theoretical maximum I believe. If it is possible to align an engine's peak torque/power and efficiency curves, paired with a CVT that can keep it at that rpm through typical driving patterns, then an ICE might come close to competing with a fuel cell. But I don't know why you would do that when there is already a more efficient option. Again for ships, trains, maybe planes, hydrogen combustion might make sense. Passenger vehicles nah.
