    Electric buses have a battery from a probably reputable supplier, with a decent BMS.

    Escooters often come from AliExpress.

    There is a difference.

      Also it’s not even a choice. Busses are not mass produced vehicles they’re regulated individually made commercial vehicles, and when the bus manufacturers say ‘were not building manual transmissions as of X date’, that’s it. It’s not happening anymore. Same with ABS, and now electric, unless you want to start manufacturing busses yourself, it’s not gonna be a choice by then.

        It’s not just that; it’s that a regulator signed off on the bus, the city has liability insurance on the bus, and the bus manufacturer will themselves be accredited and insured.

      It’s insane to ban e-bikes though since most of those come from reputable sources who are internationally recognized bike manufacturers. The people who made my electric bike also make professional bicycles for Olympians. Pretty sure the battery is reliable and isn’t going to explode.

      My bike has fallen into a swimming pool while switched on (don’t ask) and nothing happened. Literally it didn’t even register anything had happened it just carried it on.

      I think it’s worth considering banning that type of battery, but a whole category of vehicles? There could be good reasons to ban the whole category as well but then state that, instead of making up some shit about batteries.

            Cabin crew on aircraft have fireproof bags and rather effective fire extinguishers. Dealing with a battery in the cargo hold isn’t possible.

            If you want to carry a battery on an aircraft it generally has to be less than 100 (sometimes 160) watt-hours, whereas e-bike and other batteries are often 10x that.

        Aircraft typically have a limit of 100 or 160 watt-hours and require that the battery be separate or the whole device be small (think laptop sized) so that you can dump it in a fireproof bag.

        An e-bike has a ~1kWh battery that is probably strapped or zip-tied in place and there’s probably no serious firefighting equipment.

    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”.

          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

    My city bans bikes from buses because of the space they take up. Scooters and folding bikes are ok only if they’re folded up small enough not to be obstructive.

    The really shitty thing is that bikes are allowed on trains. But if the trains are unavailable and get replaced by a rail replacement bus…because it’s a bus, you can’t take your bike.

      A few years ago the same thing happened to me. There was someone who wasn’t doing to good, on top of the station building on the next stop along throwing tiles and other things off. The operator got some replacement busses, that I couldn’t get as I had my bike. So I just sat there with someone else who could get on as they had their dog. For about 4-5 hours. Sucked allot as I was tired, the dog was cute though.

    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.

    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

        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.

            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

        Quality control exists to ensure li-ion batteries don’t spontaneously combust, or at least not as often. Same reason why old timey film reels were kept under very carefully controlled environments, those things can also spontaneously combust. Any place that allows QC to be skirted will result in accidents and deaths like that elevator guy.
