Tesla truck ‘will require power of 4,000 homes to recharge’

Maybe they could put some solar panels on its roof and only recharge in daylight and/or when it’s windy.

Tesla’s recently unveiled electric truck will require the equivalent power used by up to 4,000 homes to recharge, says Energy Live News.

That’s according to new analysis by an energy consultancy, which calculated it based on the range and charge time for the megacharger.

Aurora Energy Research said the power needed for the megacharger to fill a battery in 30 minutes would be 1,600kW.

The average house in the UK uses around 4,000kWh of electricity a year, which means around 0.5kW on average.

That’s 1/3,200th of the megacharger capacity per house on average.

Head of Research Richard Howard told ELN: “The ability to charge a Tesla Semi in half an hour suggests the megacharger would need a capacity of around 1.6MW. That is equivalent to the average amount of power used by 3,000 to 4,000 houses.

“Rolling out large numbers of megachargers could create challenges for local grid infrastructure, although ‘smart’ charging solutions may be able to mitigate this impact to a degree.”

Tesla Chief Executive Elon Musk previously said the megachargers would be powered by solar.

    LOL. Back to the drawing board then……

  2. MrGrimNasty says:

    So if my quick maths is right, the entire Rampion industrial sea windmill complex could power 100 trucks. There were 300,000 registered in the UK (2014). Yer, that’s OBVIOUSLY going to be practical and cost effective!

  3. Rick says:

    Ok…obvious solution here, not sure why nobody has proposed this…
    Ever stick your hand out the window of a car when driving? Or pass a semi and almost get thrown off the road by the wind shear from the front of the semi?
    Many small but powerful windmills on the top/front of the semi. That kind of wind could push a fairly large generator from a small prop. Then the truck can be recharging the WHOLE TIME IT’S driving. !!

    Ok ok. but seriously…it takes 1.6KW to fill. 1/4 of a home’s use. How long would 4 semitruck’s tanks worth of diesel run a generator to provide a home’s electricity ?

    4000 homes sounds high, but then again is that unreasonable for a 1/2 hour at night, and what is the diesel equivelent? I haven’t run numbers, but are we comparing apples to apples here?

    If they recharge at night, that would solve some electricity capacity storage issues.

    [reply] But Musk says the chargers should run on *solar* power

  4. Craig Austin says:

    Now imagine the generation setup for a hundred trucks at a time, at every truckstop.

  5. Roger,

    It looks like the plan is for the taxpayers and electricity rate payers to pay for this and Tesla and truckers will get a well paid ride, because “it is the right thing to do to save the planet”, no matter that it won’t make a difference. It will promote their windmills and solar panels, that will make a difference, we will pay more. Their story will be, already is, there will be a lot of upfront cost but the payoff will come later, much later, and then they will say, we need a lot more money, and the guarantied payoff will just be later, much latter, then will be bankruptcy, but that was not their fault, we let them do it.

    You can bet that the bankruptcy will not affect Tesla or many of the others who made the most money.

    Pass this to someone who can turn this into something that can be spread.

  6. Curious George says:

    This strikes me as a little disingenuous. An average household power consumption compared to a peak charging power. On the other hand it helps to highlight how much energy is used for transportation.

    [reply] maybe, but if it charged at household power consumption rate it would never go anywhere 🙂

  7. Elon Musk suggests these trucks can be charged by solar energy.Considering a solar panel can produce around 150w at full sunlight to produce 1.6mW will take around 11000 panels on a bright day. 11000 panels would take up about 16000sqM of panels.These electric vehicles are just kicking the can down the road and creating more problems.

  8. PeterMG says:

    Sensible comment from Cummins on the Same days of Tesla launch.


  9. oldbrew says:

    PeterMG – link says ‘it would take about 19,000 pounds of battery to go 600 miles on a single charge’.

    That’s another headache for electric trucks. US bridge limit is 80,000 pounds so bigger battery = smaller max. payload (compared to fuel-powered trucks) = more expensive to operate and/or more trucks needed.

  10. Kip Hansen says:

    The same sort of infrastructure problem exists for all EVs — the need to upgrade home electrical drops and main circuit breaker boxes to supply the additional power needed to “quick charge” EVs and in many cases even to simply overnight-charge them.

    The idea of using the EV’s batteries as energy storage for the grid would require even more infrastructure build-out.

    In every case, massive changes to the infrastructure of any developed nation take lots of time and lots of motivation.

    E-Long-Haul trucks are very unlikely to become mainstream anywhere.

    Local delivery light trucks and vans — maybe — if they use the same plan as used for Compressed Natural Gas/Propane powered fleets — it requires a central depot for the fleet with lots of fueling capacity and short distances.

  11. Richard111 says:

    I’m baffled. Won’t the fan on the truck increase air resistance thus increasing load on the battery?

    You are proposing a PMM or Perpetual Motion Machine. They never work. Just like you can’t grasp your shoelaces and lift yourself off the ground with them.

  13. oldbrew says:

    There’s the hybrid truck…

  14. ivan says:

    That looks nice oldbrew but they have forgotten history again. Anything that causes the driver to make a sharp turn will drop the pantograph from the power line just as it did with the trams of the 60s.

    This sort of thing works with railways because their route is fixed – roads are a totally different matter with other drivers being very unpredictable.

    Sorry Mercedes, good try but you don’t get a prize.

  15. John Silver says:

    Hybrid trucks are old garbage

  17. While on the Tesla battery scam. Prof Ian Plimer mentioned in his GWPF talk last Wednesday that South West Australia has foolishly bought a Tesla super storage battery for when the wind failed or whatever (like dynamiting another coal power station). When tested it ran the grid for…. just four minutes!
    I mentioned earlier the guy at the Energy Institue evening I attended who told us that we’d all be flying around in electric aeroplanes in 20 years time. Ho hum. To get a Boeing Dreamliner airborn would require a battery that weighs around 20,000 tons (weight of kerosene on take off is around 200 tons. Ratio of battery mass/energy:kerosene is about 100:1). That’s the weight of the steel in the Severn suspension bridge. Oh, and of course to get 20,000 tons airborn requires a battery weighing… unless of course they keep it on the ground and simply fly the aeroplane on a long electrical tether wire: “Simples!”

    ‘When tested it ran the grid for…. just four minutes!’

    Just enough time to run around looking for the torches and candles – if you get a warning message 😉

    What is that in ‘Hiroshima bombs?’

  20. Larry says:

    The picture above is NOT a Tesla.
    It’s a picture of the Nikola One. Which generates its own power without being plugged in.
    Nikola trumps Tesla with their technology.

    160,000 homes worth of recharges there 😐

  22. p.g.sharrow says:

    Real Ecoloon stuff here. It will take 2 engines equivalent of generation to replace 1 engine on the road and at only double the cost for the truck. Must be a LARGE pay back in there somewhere to make the ROE pencil out…pg

  23. p.g.sharrow says:

    Oh heck I forgot! A lose of 10% of the payload weight because of the added vehicle weight…pg

  24. oldbrew says:

    No need for the weight of engine, gearbox, transmission and fuel though.

  25. Zeke says:

    “You could increase the size of the battery, but it would take about 19,000 pounds of battery to go 600 miles on a single charge. That would take a pretty big chunk out of your payload.”

    So it will just go if you haul ping pong balls out 300 miles and dead head back.
