That’s like being mad at not being able to ride your handmade car on the interstate
i dont think that an electric fleet is feasable by 2030. for one simple reason: wintertime. the way to go for commercial vehicles is for the time being dieselelectric. that means diesel generator, battery, and electric drive.
We already have a fully electric bus fleet in my city (Oslo, Norway).
Granted, when we had a period of extreme cold and snow last winter there was a bit of chaos. The electric buses did struggle a bit with range (though we’re talking -20 C), but the main problem was the combination of rear wheel drive and lots of snow.
do they have heating? maybe i am out of the loop, but last thing i read about electric busses was that they end up scrapped quite fast. i will read up on oslo, thanks.
Yes, they’re modern city buses with heating and air conditioning. Most of the buses are from the Solaris Urbino Electric line, but we also have quite a few from Mercedes, BYD and MAN.
chances are that i was talking out of my behind, i will look into it, thanks for giving me doubts. what i last read was people freezing in busses, and busses being in depots for charging all the time.
you sure those bussus are fully elctric? my impression was hybrid.
Yep, fully battery electric. The silence is glorious!
i will crawl in this rabbithole, thanks!
No? San Francisco has had electric busses for decades. They go up and down hills all the time. Their only problem is they have no batteries, so once they are disconnected they stop. It happens every day.
I think something combination of a small battery and a direct connection will work great. The battery only needs to work for an hour and the bus will be able to get around just fine.
well, obviously i didnt mean those kind of busses.
Tbf the manufacturing standards for plenty of e-scooters and -bikes can be pretty iffy sometimes, and people abuse them in ways that can increase the likelihood of issues. I concede that the vast majority of electric personal transportation devices that go up in flames usually happens during charging. A public transportation bus has to meet higher standards than a mono wheel scooter off of AliExpress.
(Imo they should be allowed on, but I can see the point in not doing so)
Honestly, they should only allow devices with removable batteries, and they could have a bucket of sand outside the bus that holds those batteries. Kind of like how bicycles are attached to the front, you’d drop the battery in and then board the bus.
But what if the battery starts burning while the bus is moving, on the road… Like in the middle of a desert (…wait… but still…)?
That’s what the external bucket of sand is for. It’ll smoke and the driver will notice in time to safely get everyone off the bus. They could then likely just detach the bucket and reboard if everything looks fine.
mmmm sandy battery, i love when my batteries have sand in them, surely this wouldnt cause problems.

there it is
I’m not gonna say bike batteries explode all the time but I will say I worked at an ebike company and they had an entire department dedicated to handling exploding battery lawsuits.
Now that’s a great green text
How about this: allow devices with removable batteries on board, and have a bucket outside the bus to put the batteries.
Boom, problem quarantined.
Assumably the bus company would be buying the bus from a company with better quality control then the Chinese ones. There were some knockoffs “hover boards” that catch on fire and that Chinese bus fire.
Battery Management Systems aren’t some new, developing technology. We know how to safely manage Lithium battery, it’s just the certain manufactures are cheaping out on the battery packs and BMS. People didn’t all stop using their phones because of the Note7 fires. People didn’t stop driving cars because of the Ford Pinto. They need to get over their EV fears and be more discerning
Hilariously most of the electric buses are Chinese. https://en.m.wikipedia.org/wiki/Yutong https://en.m.wikipedia.org/wiki/BYD_Auto
It’s the quality control and the fact that the buyer is a continent or ocean away. If a western company has hired a Chinese manufacture, they can get a good product if they stay on top of plant inspections. If not, the Chinese manufacture will start cutting corners. If you’re a western buyer, buy from a western company even if a majority of parts were made in China. If you manage to import a whole car from Alibaba and something goes wrong, you’re SOL.
Me with an e-scooter charging at home:
If it’s a cheap one, only charge it while home or somehow isolate it from flammables. Keep a fire extinguisher nearby always.
An extinguisher that can actually handle Lithium fires though. A regular CO2 extinguisher wont do anything against burning Lithium
Honestly, don’t bother with an extinguisher. The best solution is to put it in a bucket of sand on a concrete floor or something. It’s probably safer to just let it burn out than to try to fight the fire.
Also cellphones, laptops, power tools and just about everything.
Gasoline? Don’t let it inside in the house. Ever.
Who is bringing gas inside? I’m struggling to come up with even one legitimate reason to bring gasoline inside.
Eh, I keep it in my garage. If it catches on fire, the fire will spread to the rest of the house pretty quickly.
gasoline powered heaters?
You don’t often hear about laptops burning. And many of those spend their whole lives plugged in
Yes. These are extremely rare. Some models, like iirc a galaxy note and MacBook Pro have been singled out. The surface and airflow also matter. A laptop kept on a desk spends very little time charging at a time and any heat is dissipated efficiently. All devices are designed with the best thermal performance they can have.
There was actually a house fire a while ago not too far from where I live that forensics said was started by a device in a charger at night. For some units and some uses, they still fail.
Anyway. I think the better safe than sorry is warranted.
My favorite thing about my current phone is that I can set an alarm a couple of hours after I should wake, and the phone (trying not to fully charge until the alarm time) never charges overnight above 80% minimizing the chance of a thermal runaway if it happened to be like the note 7, as well as making the battery have a longer life
I was looking up e-scooters and a bunch of 1-star reviews pointed out how their battery caught fire.
Could have been fake reviews by competitors but either way, it freaked me out.
A lot of them will be fine but some of them are cheap knockoffs and they have unsafe wiring. It’s not actually the batteries themselves as they’ll probably be the same batteries it’s the way the batteries are connected up that makes them more likely to explode.
Unless you are Samsung in which case it 100% was the batteries at fault not the wiring.
Lithium batteries have a very high energy density. When that’s released all at once with a short circuit or very high current draw resulting in thermal runaway, that’s when these fires start. The great news is, they’re self fuelling fires too!
But, most reputable manufacturers, create charging/protection circuits that protect the batteries against such situations. Making them far less likely (but still possible) to happen.
The problem you’re going to get is when there’s disreputable companies, operating in countries with less stringent safety laws that are operating the production, processing and shipping entirely outside of the sight of countries with safety rules. Well, then you get a product with a fake FCC/CE sticker on it, that is very dangerous indeed.
I will not buy electronics from those sites for this very reason. Batteries, chargers and power supplies are usually very shoddy from these companies.
It’s not to say don’t buy stuff made by country X. Because there’s plenty of stuff I have bought made in, these countries but sold by companies that DO make sure there’s some testing done, and they’re not fake stickering everything. But, we all know the companies I’m talking about I think. Also, ebay (because private sellers buy in bulk from these places and then resell them) is something to be careful of too.
It can also be due to unsafe charging (over-voltage) or unsafe discharging (over-current, generating too much heat). The actual fire doesn’t necessarily happen immediately during charging/discharging.
It’s certainly an issue with some of them. I wouldn’t buy a random no name one from alibaba. It might be safe. Or not.
A home here burned down. Stay safe kids.
I keep my scooter at the farthest point from the apartment exit just to be on the safe side. I also haven’t heard many bad things about this particular model (Ninebot G30 Max).
rEAsOn bEinG Is 🥴
Meanwhile, TSA: no water bottle for you. Bring a cell phone, laptop battery, and a spare 20,000 mAh backup battery (of dodgy provenance no less)? Sure no problem.
Loved this when I was vaping and would travel for work.
Give me a ton of shit over my variety of juices, in 30mL bottles in my 3-1-1 bag…but the half dozen loose 18650s? Not a problem.
(They weren’t totally loose, I had silicone sleeves on them and would rewrap them if they showed a little wear on the wrapper. I used mechs and RDAs, I wrote the newbie guide to rebuilding on reddit…I was pretty safe about it).
Hey just wanted to let you know, I’ve read every single post in this community and will continue to do so for the foreseeable future every night before bed when I use lemmy to claw some precious time back from the eternal grind.
Thanks for posting.
I second this, it’s nice to come here every few days and read through all the new posts. :)
I’m glad you’re enjoying these. I’ll keep logging in to post greentexts until I forget.
Where do you find these? I go on 4chan and it’s mostly porn…
I’ve just been saving random greentexts for years that get posted elsewhere. It’s much better than trying to sift through the porn and other garbage yourself.
Please don’t use retarded in this manner
This is 4chan, not something the poster said, 4chan is a cesspit, and this is to be expected.
Who are you talking to? The 4chan user that posted this last month on 4chan?
People used to say the same about cellphones.
I remember one episode where a girl in the bus was texting and some old lady got up to tell her that “it will go into the engine”. The old lady was terrified.
That reminds me of something.
Also on a bus. There was a group of girls on the bus and they were having a big loud argument about whether or not one of the group would receive a text from her partner or friend or whatever because “how would the text know where they were, as the bus is moving”.
A valid question. Luckily a lot of work has been done to address it.
Pretty much the first thing that needed to be solved when moving from 1-way pagers to 2-way phones. Pagers could just get a broadcast analog signal and determine themselves if they were the intended recipient. 2-way needed more bandwidth and a dedicated communication channel to a specific device, so broadcast wasn’t feasible. Thus, phones would send a registration signal that a tower would pick up, and that specific tower would handle all communication to that phone. If another tower got the registration signal, communication would switch to that tower.
Interestingly enough, there was a period (for a fairly long time) that if you were travelling too fast, you could either a) not be able to register on a network, or b) overwhelm the network with registrations - part of the reason why phones had to be turned off on airplanes
More likely that’s the insurance company’s call
