    A week or so ago, Tesla unveiled their 18 wheeler. According to reports, it has a 500 mile range hauling about 80,000 lbs at 65 MPH. The recharge time was not revealed, or at least I did not see it. However Tesla did indicate it could be recharged with a "V4" charger, apparently with an even higher charge rate than their "supercharger" system.

    The capacity of the battery in kwhs was not revealed. But it was powered by a tri-motor system, so the total power available for grades and acceleration will be more than today's diesels. I am guessing two or three times as much available power.

    I will have to see one hang with a 600 HP Cummins in real world conditions.

    If the Wikipedia story is right, and the Big Rig consumes 1.7 KWh/mile, then to have a range of 500 miles, it would use about 850 Kwhs. So the apparent capacity of the battery will come close to 1000 KWh.

    The "V4" battery charge system may be called the "Megacharger" because its fluid cooled connector can handle such high voltage and current, it could charge at the rate of one Megawatt/hour. Thus the full 500 mile range could be restored in about one hour. Amazing if true.

    If a car/SUV charger could charge at that rate, then a vehicle with a 145 KWh battery could be recharged to full range (say 500 miles) in less than 10 minutes.

    That just means it will be a two to three times bigger fire when the stupid battery melts down.

    peace to you

    It seems you have bought into the disinformation campaign against BEV's. Basically there are more vehicle fires in fossil fuelers.
    Not just in absolute numbers, but in the rate per type of vehicle.

    But yes, the lowest rate for battery fires is for LFP battery cell chemistry. According to Musk, that battery will dominate the future.

    So, the man selling electric cars says electric batteries will dominate the future?

    Ok, believe what you want

    Not what I said at all. Are you really trying to address what I said, or score points. The LFP battery chemistry will dominate over the other chemistries because (1) Cheaper, (2) less fire prone, (3) longer lasting and (4) can be recharged to 100% capacity.

    You said….
    I said…
    You replied….
    Impossible to have a conversation with someone who doesn’t even know what they just posted.

    Bottom line, electric batteries are too cost intensive to produce, they use an enormous amount of scarce natural resources to produce, they are not recyclable, they are a hazard to dispose of because of the concentrations of heavy metals and they only last about 5 years and worst of all, the stinking communist Chinese have cornered the market on production.

    Now, just recently I read a story about scientists making progress with cold fusion. That is the future, not EV.

    peace to you

    When the EV does catch on fire, it is hard and expensive to put out.

    I see you did not address my post, but again posted disinformation.
    1) What are the heavy metals in LFP batteries?
    2) There are lots of Toyota Hybrids on the road with batteries over 10 years old.
    3) Yes, China is ahead because the Leftists in Washington dithered.

    I think the Firefighting organizations will develop a best practices plan to handle battery fires.

    We aren’t talking about “hybrids”, we are talking about full EV.

    The batteries last about 5 years

    So those 2012 Tesla Model S vehicles all have new batteries?

    Quick google search. Electric car batteries usually last 10 years or so if you live in cold climates. Hot climates (California) will greatly reduce life span

    This post is doublespeak for BEV batteries can last longer than 5 years. Decoded at no charge.

    I said they can last longer than 5 years as long as the air temperature doesn’t get above 85 degrees in the summer where you live.

    Keep pushing the EV. In 20 years we will have hundreds of thousands, if not millions, of toxic, poisonous batteries that cannot be recycled or disposed of because of the concentrations of heavy metals.

    They will store them, like the toxic waste they are, in underground bunkers where they will, eventually, spontaneously explode producing a cloud of toxic poison gas that drifts across the country killing everything in its path. The toxic burn will last for decades, millions of people will die, many more millions will suffer debilitating illnesses.

    Then, all the radical marxists that pushed the EV will blames conservatives and capitalism.

    peace to you

    Sir, you are the one posted anti BEV nonsense nonstop. There are plenty of Teslas in California that are older than 5 years and still going strong. Your claim is fictitious.

    I already asked for the "heavy metals" in LFP batteries and you ignored the question, but now repeat the fictitious claim that LFP batteries cannot be recycled. It is true the market will not now support recycling but it is a cost rather than a chemistry problem.

    Yes, it is a chemistry problem. The batteries cannot be recycled, they will eventually explode (just like every other battery ever built ie your flashlight batteries and all others, and they will release toxic gas and heavy metals into the environment.

    peace to you

    Right now best practices is foam. Foam is bad on the environment and causes health risk to those using it.
