    Electric vehicle battery fires - what to know and how to react
    It's very rare, but lithium-ion batteries in electric vehicles can catch fire.

    Good to know how to react when you electric car is on fire...

    So sales of fire extinguishers will plummet as there is no point in
    carrying one.

    I do not even have one, but to get out of the upstairs bedroom here I have a rope ready...
    Downstairs a 250 Ah lipo battery pack, those are supposed to not ignite
    I have no 'lectric' car (yet?)
    My bike will be OK...
    Lots of Lipo batteries around the house, drone, radios, all sorts of stuff.

    Storms here, maybe I should get a wind powered generator
    may need a building permit ....
    Solar panels I have, some flexible ones too for on a boat.
    I have never had a phone on fire....

    ALL modern cell phones use LiPo pocket cells. If your cell phone has
    a shoulder strap and is quite heavy, it might be Lithium-Ion. However,
    if your cell phone battery is small, flat, and cannot be removed, it's
    a LiPo pocket cell. Same with a variety of battery powered
    rechargeable devices (Bluetooth speakers, recent rechargeable TV
    remote controls, drones, RC toys, walkie-talkies, COB-LED flashlights,
    etc).

    Good advice.

    Storms here, maybe I should get a wind powered generator
    may need a building permit ....

    Wind turbine generators usually have a means of "feathering" the
    turbine blades to prevent spinning to fast. The last thing you want a
    turbine to do is free-wheel above its maximum RPM rating and launch a
    blade through your roof.

    Solar panels I have, some flexible ones too for on a boat.
    I have never had a phone on fire....

    No phone fires, but we had a dumpster fire at my former office that
    was started by a cell phone "battery bank". This was an early model
    that used Li-Ion cylindrical cells (not LiPo). There have also been
    three(?) eBike fires, which also use Li-Ion cylindrical cells with the
    added bonus of a home made battery packs and chargers. I'm not
    including the local idiot who decided that only save way to dispose of
    a cordless tool battery pack was by first drilling holes in it.

    For your amusement, this is a clone Ryobi OP4060 cordless tool battery purchased on eBay(?):
    <https://photos.app.goo.gl/S35ScvADzdoM22gFA>
    Notice that it use two different (mismatched) Li-Ion cell types, the
    thermistor is not glued to a cell, one of the FETs melted, and the
    "fuse" didn't blow. I inherited three of these from a customer after
    he replaced them with OEM batteries. There was no fire. I could
    repair the packs, but instead, I'll probably scavenge the cells and
    use them something else such as flashlights.

    According to what I've read, the danger comes from the vapors produced
    by overheated electrolyte. The most common type is a Lithium salt and
    an organic solvent mixture. I would expect that some of this vapor
    might be detectable by a hydrocarbon gas detector such as a VoC
    (volatile organic compound) gas detector. <https://www.google.com/search?q=voc+gas+detector&udm=2>
    I haven't done anything with this idea yet, but it's on my "yet
    another project" list.

    Yes, much can go wrong, good thing it did not catch fire.

    Sensors is interesting,
    https://www.tinytronics.nl/en/sensors
    I have some of those MQ gas sensors, some are sensitive to many different gasses
    https://www.tinytronics.nl/index.php?route=product/search&search=MQ%20sensor

    The MQ4 I have on POE ethernet does detect combustable gasses:
    https://www.tinytronics.nl/en/sensors/air/gas/mq-4-gas-sensor-module

    The MQ7 I have on an other POE ethernet module detects carbon monoxide:
    https://www.tinytronics.nl/en/sensors/air/gas/mq-7-gas-sensor-module

    I also have a nice CO2 sensor from ebay:

    https://panteltje.nl/pub/MH-Z19_CO2_sensor_optical_chamber_IMG_6075.JPG

    So much to play with, you may get false alarm on the MQ7 if you use any alcohol ..

    Well I am close to the coast.,,
    there is always some wind, mostly from the west.
    Last week I had to cut away at the roses that grow next to the frontdoor
    as those were continuously slammed against the door and mailbox by the wind. Roses have nasty dorns...

    Last few days was weather alarm in much of the country, trees on cars,
    Heavy lightning too, buckets full of rain.
    I disconnect some stuff to protect it from lightning
    Satellite disk primary target?
    Now some warm days are coming .. it says.. more garden work planned..

    When things get hotter I may need to plant some cactus plants...

    Recently I saw a video of a dog chewing on a battery pack.
    He was very startled when it caught fire and set the rug on
    fire.

    So don't let your devices lie around when your pets can
    reach them.

    There is a video online with a guy who enters a shop, puts a battery in his pocket, and his pockest catches fire.
    He probably had a pocket knife or something metal in his pocket too, short...

    Only if you want to annoy your neighbours with a loud whirring noise
    when the wind is blowing. Of course, it depends on who you believe, and
    who is providing full information. See <https://tesup.com/uk/blogs/post/how-loud-are-household-wind-turbines>
    From the information these wind turbine sellers provide it looks looks
    really good - only 35 dB!

    See the same graph at <https://windexchange.energy.gov/projects/sound>,
    and you'll see that states the sound level is the same. BUT it also
    notes in the caption under the graph "At 300 meters away, which is the
    nearest distance a wind turbine typically is to a building, the sounds
    produced by a large wind energy project range from 35–45 decibels..."

    So as long as you're 300 metres (1000ft) from the domestic turbine the
    sound level shouldn't bother you. How many urban or even suburban areas
    do you know where the 300m distance is likely?

    and you'll see that states the sound level is the same. BUT it also
    notes in the caption under the graph "At 300 meters away, which is the >nearest distance a wind turbine typically is to a building, the sounds >produced by a large wind energy project range from 35–45 decibels..."

    So as long as you're 300 metres (1000ft) from the domestic turbine the
    sound level shouldn't bother you. How many urban or even suburban areas
    do you know where the 300m distance is likely?

    If they hadn't specified that, they could have got away with almost any
    noise level. In some cases, dB(C) is more useful if the noise contains
    a lot of low frequencies. For non-electronic music, the dB(C) reading
    is generally about 10dB higher than the dB(A) reading.

    Good to know how to react when you electric car is on fire...


    I used to work with a fire alarm company in New Jersey. I designed
    next-gen fire systems for high-rise buildings in Manhattan.

    They had a sign on the wall that anticipated Lithium batteries:


    IN CASE OF FIRE

    RUN, YELL "FIRE"

    Good to know how to react when you electric car is on fire...

    So sales of fire extinguishers will plummet as there is no point in
    carrying one.

    I do not even have one, but to get out of the upstairs bedroom here I have a rope ready...
    Downstairs a 250 Ah lipo battery pack, those are supposed to not ignite
    I have no 'lectric' car (yet?)
    My bike will be OK...
    Lots of Lipo batteries around the house, drone, radios, all sorts of stuff. >>>
    Storms here, maybe I should get a wind powered generator
    may need a building permit ....
    Solar panels I have, some flexible ones too for on a boat.
    I have never had a phone on fire....

    Recently I saw a video of a dog chewing on a battery pack.
    He was very startled when it caught fire and set the rug on
    fire.

    So don't let your devices lie around when your pets can
    reach them.

    There is a video online with a guy who enters a shop, puts a battery in his pocket, and his pockest catches fire.
    He probably had a pocket knife or something metal in his pocket too, short...

    One day I felt a burning sensation on my leg. It was a regular 9-volt
    battery shorted by some coins.

    When I was in high school chemistry class, we had some little
    coin-sized radioactive samples, and I'd carry them home in my jeans
    pocket. So far so good. The kids seem OK.

    Seems a good advice.
    For small batteries on fire I would use big plyers and carry it outside
    or toss out of te window if upstairs, also using the plyers of course.
