facthunter Posted July 20 Posted July 20 Seems to presume it is a common occurrence. Lots of water, is the Key to dissipate the heat. You'd need fire Hydrants everywhere.. Nev
onetrack Posted July 20 Posted July 20 You'd only need the setup in cities. Out in rural or remote regions, the EV could burn itself out without much need to put it out immediately. Once a car starts to burn, even a small wiring fire, it's a write-off, anyway. 1
facthunter Posted July 20 Posted July 20 In a carpark Tunnel or Boat is where the problem is acute. Fuel tankers are a risk also and service stations particularly with LPG and the ignorance people have of it. Its probably more dangerous filling a normal car than charging a battery car and you can't leave it and there's static electricity and flame issues as well. with Hydrocarbon liquids. Nev 1 1
old man emu Posted July 20 Posted July 20 5 hours ago, facthunter said: Seems to presume it is a common occurrence Is a vehicle fire possible? Yes Are they frequent? Depends on the number of vehicles of any power supply sort p[resent in an area. Obviously there are more vehicles in cities than in country towns. However how many tools do you have that you only use on rare ocasions? That spray bar could sit in a truck for years withiout being uses, but it would be invaluable on the one day it was needed. 1

red750 Posted July 20 Posted July 20 But e-bike fires keep causing problems. A couple of houses burnt down as a result of an e-bike fire. And many people getting killed in accidents featuring e-bikes.
facthunter Posted July 20 Posted July 20 Unrelated. E bikes catch fire when the charger is replaced by an unsuitable one also as I pointed out without a fire Hydrant the gadget is useless and it's specifically FOR ELECTRIC Vehicles that USE water to COOL the fire. Fuel fires are a different matter entirely. Nev

kgwilson Posted July 20 Posted July 20 EVs are 20 to 80 times less likely to catch fire than ICE vehicles. There are numerous studies and facts around this and a lot of false claims from the anti EV lobby. The real issue is how to deal with thermal runaway when it happens. An Australian organisation https://www.evfiresafe.com/ has very comprehensive information. The problem is present in every lithium battery & these are everywhere especially in phones and battery powered gadgets. People keep throwing them in the rubbish & then fires start when they short circuit. E-bikes and scooters are a far bigger problem as idiots use the wrong charger and buy cheap poorly manufactured ones on line. 1 1

I had to include ICEs and Hybrids so that the comment would not be diverted to a discussion of the number of fires in those typres of engines. I simply think that it is a useful tool for dealing with a vehicle fire where there is access to a reticulated water supply which can provide water at high pressure. 1
octave Posted July 21 Posted July 21 Here is another innovation. I guess in the early days of passenger aviation, fire was a problem; however, this spurred on innovation and specialised firefighting techniques. Firefighting generally has to keep up with new technology. Many years ago, fires were simpler; now we have oil refineries, chemical plants, and more. I do believe that we need to take Lithium fires seriously, although rarer than other fires, the consequences can be more dire. Certainly, as battery chemistry changes, EV fires will be almost non-existent . 2
spacesailor Posted July 21 Posted July 21 I had a thermal runaway on a 'new Aldi solar rechargeable torch ' , my daughter had it plugged into her car, and also in the the windscreen. so, getting triple heating . Smart thinking , " throw it into the freezer " . It worked , cool enough to return it for replacement. Daughter won't use it , so I now have two great power-bank flashliights.. spacesailor

Just in case anyone misunderstood, when I marked Jerry's vid as 'informative' - that was for it's insights into the delinquent social life cycle of Escooters & Ebikes. Not for the video's misinformed BS about battery fire risks. 1
Jerry_Atrick Posted July 21 Posted July 21 Yes.. it was a little bit of a sarcastic post, I have to admit.

red750 Posted July 22 Posted July 22 Slightly off topic, but I saw a video today of a humanoid robot which could change it's own battery. It backed up to a battery cabinet, reached behind itself, slid out the flat battery and placed it in the storage cabinet, took a charged battery from the unit and inserted in the battery slot in its back, thus enabling it to work 24 hours a day. 2
old man emu Posted July 22 Posted July 22 Robots were supposed to be able to work 24/7 without break. Now they are required to take a break to recharge. Definitely a backward step. 2
facthunter Posted July 22 Posted July 22 Most Robotics are firmly attached to a structure.. Ones that move around get all the attention. Nev 1

Does it chuck a wobbly when it finds the replacement battery hasn't been charged, because the power went off, when the battery was supposed to be getting charged? 1

onetrack Posted July 23 Posted July 23 Why aren't the women doing something to stop the robot! They're the most powerful weapon the blokes have on board!! 😄
red750 Posted July 23 Posted July 23 Here is the video of the robot changing its battery pack. https://youtu.be/mHP1WGlw5Wk?si=bfrX2ootI5cz6HbG
octave Posted Monday at 08:21 AM Posted Monday at 08:21 AM (edited) Here is a video of my son's business partner and his EV mini track vehicle. He designed and built this EV. Most of these parts were 3D printed on a printer that they built themselves. My son owns a huge house (2 houses in one) with his business partner and best mate. When we visit (NZ) we roam the whole house, and we're quite likely to sit on a sofa and find we are sitting on a circuit board or other device. etank.mp4 etank.mp4 Edited Monday at 08:21 AM by octave 1
