Really though, if you're reaching the end of your battery capacity with a lot of EVs out there today, you've probably been driving for about 3-4 hours or so, if not longer, the general recommendations I've seen are you should really stop and get a 15 minute break about every 2 hours to stretch your legs, prevent fatigue, increase alertness, etc.so that's pretty much in line with the recommendations. I know that's pretty much the rhythm I and most other people I've ridden with tend to fall into on road trips without even trying. And very often despite my best efforts, rest stops tend to end up lasting around a half hour anyway because of checkout or bathroom lines, or one of my travel companions taking their time ordering food or getting distracted somewhere.
I get that some people can just power through much longer drives, and I've occasionally done it, but honestly it's probably for the best if people are made to stop every couple hours and hit the reset button on their brains, a lot of people are shitty enough drivers when they're fresh and well-rested, let alone after theyve been screaming down the interstate at 70mph for hours, and their brain is getting fatigued.
It's double the recommendation in a best case scenario. It's 4x as long a wait if you have to get in a queue.
I've never had a rest stop that takes more than 10 minutes and that's if I have my toddler and wife.
If you want to stay forcing some drive time limits on people go ahead and try. But saying YOU get tired so everyone else must only be able to handle 2 hours at a time is insane. I'd be far far more tired showing up to my destination after an extra hour or two off driving and probably getting dark at that time.
I call BS. I have given diaper changes to my kids on the road that take more than 10 minutes. I won’t even mention lunch breaks, dinner breaks mid morning snack breaks, pooping breaks etc.
Diaper changes are a 45 second affair, 3 minutes if its a mess, and we're past that personally. We're in and out for toilets and have our own food packed. I commonly don't need to use the rest room and the wife will take care of everything while I hang out at the pump and pick her up. 5 minutes.
Not everyone lolygags around
true. resting each 2-4 hours is nonsense. a solid 8 hour drive and u get to sleep at ur own regular bed time beats them all. Evs need double the mileage (thus double the battery capacity and charging speed) so they could achieve this. other than that, it is just a car for vegans.
how about you recognize that your use case is very much in the minority and covered by alternative solutions like Hydrogenation powered cars?
sure you might want a car with 1000 km range and you can get that along with semi-trucks you can hop on the Hydrogen platform , but statistics show that the vast majority of driving people do is well within the ranges of current BEVs, so why make all cars carry around all that extra weight, the expensive batteries when the vast majority of it won't ever be used?
hydrogen is costly: it requires 44kwh of electricity to produce 1kg of H2, and that translates to 80km of mileage. while a 100kwh electric battery give u 300km mileage. also how much does a battery cost: 100$/kwh, ie 10k$ for 100kwh pack. i would gladly pay an extra 10k$ to have double the battery size, if just companies stopped being greedy and implementing stupid features like fast 0-60 acceleration, that eats up on mileage, and snake oil regenerative braking, and aero trunk spoiler for extra 10km mileage, for the price tag of 1k$ or god knows how much..i would gladly ride my pack at 110kmh with no brutal accelerations, and it would get me to almost everywhere i go. i shouldnt be needing a separate car to access remote areas, or always have to be anxious about range. minority ? hmm, well not everyone lives in the G7 countries, so we dont have a supercharger in each 100km radius. probably there are 5 or 6 V1 tesla chargers in 150k km² surface area where i am now
da fuck.
How often do you go to these remote areas? how many of these areas are out of reach from you on a full charge?
except there is more cost to a double battery size than just money, look up how the metals are mined for these batteries.
Doesn't matter, it's gonna be used for semi-trucks anyway, it can be manufactured anywhere and solar energy is abundant so is water, much more abundant than what we use for the batteries we have at the moment.
you also have to start to factor in road wear if you start doubling battery capacity.
not a concrete answer
not much but, but people who really do would appreciate an electric 4WD, not a cybertruck gimmick. i meant by remote that there no supercharger in 400km radius in sight
They use carbon and LiFePo4: Lithium,metal, and phosphorus, which are abundant. no more child mined Cobalt with NMC cells, according to Musk at least..
sure bro. solar generation capacity is at 200w per m². u would need to cover whole Russias worth of land to produce sizeable amounts of hydrogen. also installing panels in the desert isn't effecient, their efficieny drops alot when they are at temps way beyond 26°c
always has been. doubled the capacity or not. road wear affects tires and brakes more most of the time. battery wears at 100k miles or so, i am not sure, so not frequently swapped afterall
by road wear I mean that if you start adding more and more weight it will significantly increase infrastructure costs of keeping the roads maintained
it's a fitting response to your non-conrete statement about regen braking.
Oh so it's not even you are arguing for, it's these mystical other people.
okay, what the fuck does a non-product like cybertruck has to do with anything?
Are there people like that? I am from Slovakia which doesn't have a great infrastructure and I don't believe there are even people like that here.
what the fuck does desert has to do with anything?
no you dont...
