Time to invest in coal mines to power up to batteries with.
LOL, but my doc is blonde with a Scandinavian name.
A fuel cell is not a battery. It generates electricity from hydrogen. It does not recharge from a power cord. You put hydrogen into the fuel tank instead of gasoline.
Heat dissipation during charge and discharge will always be an impediment to severe miniturization of batteries. You’d need a chemistry with almost zero internal resistance.
Di-Lithium crystals encased in clear Aluminum??
Coinkydink.....I’ve been seen recently by a gyno-obstet female. Very attractive, and she’s helping me. She has male patients, too. It’s a long story. Nothing kinky. I’m 80 years old..but I still have 20-20 vision.
Good for you. I’m 68. In fair shape.
Bttt
Having done a career in engineering I’d say its pretty much hit or miss.
When time is money- how does this translate to good trucking sense if they have to have hours of downtime waiting for it to charge?
15 minutes to recharge. Time enough to pee, and grab a coffee and a sandwich.
naughty naughty- you didn’t read my posts did you? I explained why i thought what i did- it seemed incredible to me that a ‘battery’ could charge in 15 minutes- I looked online for more info and found, at first, that folks were saying around 12 hours- but turns out that was for another type- then I found the one article about Tesla truck that it takes about 40 minutes to bring enough charge to go about 400 miles- The problem was i was confusing this thread article with the last one i found which also was about a different technology- but i didn’t catch the difference right away-
But thanks for commenting-
Yes i got that now- I was tired and wasn’t making hte distinction between battery vehicles and hydrogen- it was a mix up on my part- that’s all-
Makes me think Nikola is near bankruptcy and is looking for a merger. Hydrogen is a dead end.
Over the road truckers are limited in the number of hours per 24hr period they can drive by federal law. 800 miles exceeds that time limit for a single driver. Yes I know about driver teams that exist to get around this limitation.
The current level 3 DC fast charger standard tops ouy at 500 kw, the next level is going to be 1000kw. None of these trucks will have a megawatt hour pack so charge time will be under an hour even a huge 500kWh pack is a half hour charge. Think lunch stop or dinner.
The trade off is electricity is one fourth the cost of diesel, there is virtually zero maintenance on a electric motor and the MTBF of a electric drive train is millions of miles. Every train has electric traction motors some get the electricity from diesels some don’t but almost none are directly driven by the diesel. Humans have mastered electric drive in trains, ships, heavy mining dltrucks, light rail the list is endless.
The hold back for semitrucks has been battery energy density and charge acceptance rates. This new battery solves the energy density problem and charge rates have already been solved Tesla will have 1000kw charger deployed in a year or less 1000A @ 1000v sounds scary till you realise 12 feet above ground almost anywhere in America you can find 6000-15000v AC on your humble neighborhood power pole. The volts and amps is irrelevant to the user the chargers are cold terminals until they get a complex digital handshake over the shielded and completely connected cables,one simpley cannot be shocked by a modern super charger they are safer than your always hot wall plug ever could be. EVs are the future once batteries cross $100 kwh in cost, Tesla has already got cells near that cost and will cross that line this year. Why $100kWh? That’s where the math works out that over a 100,000 mile life the cost per mile is lower than any ICE of equivalent vehicle size and quality point. Factor in the fact that most EVs will have a half million mile pack life as already proved by Teslas in commercial service, and the new Model 3 have a million mile drive train life by design and the cost of owning an EV is now an order of magnitude less than an equivalent ICE. Tesla gen 2 model 3 will have a million mile pack and is designed from the start for commercial taxi use ...autonomous robot taxis that is via the Tesla Network.
I personally have bought my last ICE vehicle 100% of my 38000+ mile a year drive cycle can be handled by a Model 3 LR 320mi and I travel 800+ mile round trip to Midland, Houston and New Orleans from Dallas on a twice monthtly basis. The M3 is 250kw level 3 with 500kw a over the air upgrade away and the 1000 is coming next year probably by the time my current ICE ends its life at 200k miles. Even with 250kw that’s 1000 miles per hour of charging rate or 15 minutes to go from 20 percent to 90 percent which is the ideal charge window for a tesla. I stop at least twice on the way to New Orleans that’s 570 miles one way to eat and piss so it’s little extra to stop at a place with a colocated supercharger they are all along the interstates already.
Thank you for that info JD- That certainly sounds like a pretty quick charge and turn around time- The info i got at first, regarding full battery run trucks, was it would take about 12 hours to charge- but that was either wrong, or for a different technology or something obviously-
[[or 15 minutes to go from 20 percent to 90 percent]]
That’s what i was wondering- how long from near fully discharged to approx full charge- 15 minutes is wicked fast- pretty cool
[[supercharger they are all along the interstates already.]]
Looks like we’re heading toward mostly electric- when it comes to trucking, in the not too distant future-
L8r
Right after Algea replaces the need for oil.
its good that electricity is free and grows on trees....
The ‘perfect’ battery is only TEN YEARS AWAY!...........
