Comment on World's largest sodium-ion battery goes into operation - Energy Storage
JoshuaFalken@lemmy.world 4 months agoA 300 Mi charge would mean if you can’t charge daily, you would be able to go a couple of days without having to do so.
Given most trips are less than 3 miles, if you had a 300 mile range vehicle, that’s about three months of average driving, not a couple of days. My point was that people don’t go on long drives the vast majority of time and don’t more than fifty or so miles of range.
I’ll use Tesla as the example here only because it’s the prominent electric car brand. Directly from them:
A 120 volt outlet will supply 2 to 3 miles of range per hour of charge. If you charge overnight and drive less than 30 to 40 miles per day, this option should meet your typical charging needs.
They go one to say you can get a 10x improvement on the miles per hour when charging from a 240v outlet. Even accounting for installation of a new outlet to the garage or side of the house, this would be far cheaper than buying a vehicle with hundreds of miles of range and using a supercharger every other week.

I live about 5 miles from work. I usually drive about 20 miles a day, so about 140 a week. I also rent an apt where there are no options for a charger. I considered a mini Cooper se and even a fiat 500e for a bit (it’s really cheap when you can find it), but once I looked my driving, I was only going to be comfortable with a 200 mile range for the occasional (once or twice a month) trips that are 100 miles one way. While chargers along the trip might be available, most times I’ve seen them they are clearly broken (provided it isn’t tesla, which seems to repair them). I do live in a city, but even then the 100 miles range would be tough to accommodate. Not saying impossible (I’ve seen electric mustangs and electric Chevrolets in my apartment), but a range of 100 miles is a lot less feasible for most than I think the data suggests, although that might also be fine if charging was faster.

Don’t get me wrong, obviously people like yourself make these long ish trips regularly and you’d benefit either from more range or better infrastructure. If, like gas stations, there were two hundred thousand charging stations sprinkled through the country, less range in the car would be less of a concern.
I know someone from my college days that hung a 100’ cord out her third story window to plug in her little EV. Nissan Leaf or something of that class. Worked like a charm for puttering around town.
I’m sure the data isn’t perfect, but as far as the averages go, it’s accurate for my driving patterns. Those trips you’re taking nearly double your yearly mileage, so that would certainly change your average. Without them though, you wouldn’t be too far off based on what you’ve described. I’m fortunate that I live near a train line for my regular trips out of town. Not an option for the vast majority unfortunately.
Another option a couple I know took was a hybrid. Most of the time they don’t use the engine, but when they go see family or what have you, they’ve got the range they need without having to find a charger. Pretty convenient if you ask me.
Eventually we’ll have charging stations all over, or maybe light rail, and going hundreds of miles in a day without a thought to battery depletion, but I doubt I’ll be around to see it.

Oh, I don’t doubt it’s possible, but getting the avg person there is the issue. At my milage, if I really absolutely wanted to go electric, an ebike would frankly be a better option (admittedly, much harder to haul stuff, much less safe, and annoying during the summer which is very hot in my area) for low range stuff. Phev Hybrids are a decent option, but again, if you don’t have a place to charge at night a lot of the benefits are neglected. Not gonna lie, I do actually suspect that that will change in the next 10 years, as tesla have finally hit critical mass I my area, and they are much cheaper to fuel, something that isn’t highlighted enough in my opinion. And I suspect that sodium batteries will more than likely cause it. Having something incredibly cheap to drive is more than likely what will turn the tide of evs, and it is why I am very annoyed that Chinese evs aren’t being imported into the US without insane tarriffs. Once cheap evs are common, the need for charging might actually get some real notice. That being said, I think my considerations aren’t very far off from the concerns of many buying cars right now, and at the current moment those without a range of at least 200 miles are a much harder sell (and why lower range vehicles don’t seem to sell on the used market).

The used market is different for EVs than a combustion vehicle. I looked for a BMW i3 a while back and was only finding them halfway across the continent. Maybe that’s because people keep them for longer? Not sure that market has developed enough to know one way or another.
I understand what you mean about the average person getting it, and while that is important, I think the primary issue is the limited selection of small EVs on the market. As you point out, if foreign vehicles could be acquired without the steep cost, more people would drive them. As it stands, domestic automakers don’t want to make anything but twenty foot long SUVs because of the huge profit margins on them.
As far as ebikes go, I am definitely on that boat. Don’t have one myself - call me a traditionalist - but I wish more people would consider them. I agree that in higher temperatures, or humidity which I find worse, it’s uncomfortable. Though the benefit of (maybe idealistically) not having a car payment and associated insurance go a long way to making that discomfort palatable.
Personally, I’ve got a trailer for my bike that I’ve been using to ride 10-15 minutes to the grocery stores and do errands. A time or two I have even gotten some lumber with it from the hardware store. I thought about a specific cargo bike a while back but decided not to have an entire bicycle for that sort of thing. The trailer is smaller anyway.
The safety factor of riding opposed to driving is the most important factor in my mind. It’s dangerous to ride along the side of a multi lane road. Paint doesn’t stop drivers from crossing into a ‘bike lane’. Even a curb or those plastic bollards are insufficient in my mind. I ride nearly primarily on trails or the type of streets that are small enough not to have any painted lines. For busier routes I use the sidewalk or even the boulevard if there is one.
The more people getting on the ebike wagon could cause better riding options to be developed in the area. That’s political though. Even if it doesn’t, it’s one more person taking a trip not in a car, making it a tiny bit safer.
