As Tesla has announced their new semi truck which runs on an 850kwh battery, simple physics and engineering principles reveal the following: 850kwh contains approximately the same usable evergy as about 70 gallons of standard diesel fuel This would show a range on an average semi of 450-500 miles

After which, the battery must be recharged. To do this in one hour(and IDoubt you will see this) would require a generator of 1000000 watts, or one megawatt(approximately) At 480 volts, three phase, the most common industrial grid voltage in the US, this requires about 12 wires ,each about the size of a large mans thumb, to carry this much electricity Or, about the average use of more than 400 houses. This is per truck. Cannot see this happening.

Is there supposed to be a link or something?

How about a gasoline tanker truck? Drivers staying overnight at a motel should take the room back, way back, from the lot.

Governments want electric vehicles because they can be tracked and controlled. They can be turned off. A nice 65 Mustang has to be spotted on the road. You can fill it up anywhere. And the driver is the only one who can turn it off.

A Tesla loses energy all the time. A battery stores energy for a while but it also loses energy as it sits. Or as the temperature cools. Or as the batteries degrade.

Moving to electric is less about the environment and more about government control.

A rough calculation shows 1.2 million pounds of water needed to douse a battery fire. (scaling vs. current ev car fires).

You obviously did not watch the reveal.
It operates at 1000 volts, not 480v. DC not AC nor Three phase. You sound like a guy with electrical knowledge of AC. DC is a different world.
The charge cable is about the same size/thickness as the cars, do to higher DC volts and active (liquid) cooling.

You are also confusing MW rating of a charger with usage over time. At your house you are are charged at KWh, 1 kw for 1 hour. It is the same AMOUNT of electricity if I take 10kw for 6 minutes. DUH.

It’s possible, it’s happening. Now what we should do about the power grid is another topic. I happen to work in IT. IT consumes WAY more power than all the electric cars on the road today. Nobody says beans about it.

This may come as a shock to you, but we have lots more power infrastructure today than we did in 1940. We build these things called power plants. They can run on nuclear. They can run on natural gas. They can run on coal. I prefer nuclear and natural gas, but hey, let the best/cheapest win. Get the government red tape reduced and start building SAFE nuclear plants....See the cost of energy drop to 1-2 cents/KWH.

Why wouldn’t it be a hybrid? Makes no sense otherwise.

The bad news is the trailer they haul behind is completely full of the batteries. No room left for cargo.

You should watch the video. One of the features of the Semi is regenerative braking. When a Semi comes down a mountain, it doesn’t use the brakes. The change in PE is put back into the battery. This makes trucks on hills much safer for everyone. There are three motors. One for cruise and two for torque. Shifting is automatic responding to operator demand.

Also, there is a megawatt charging station that goes with the system. The charging cable is liquid cooled to reduce size to about that of a standard Tesla supercharging station.

“To do this in one hour(and IDoubt you will see this) would require a generator of 1000000 watts, or one megawatt(approximately)”

Tesla has stated 30 minutes for a 70% charge using their 1000 kw charger.

Musk needs to dump this idiotic idea and focus on more important things like Twitter and SpaceX.

Electric vehicles are fine for small cars running around in an urban area (if you live in a single-family home and can install a charger to recharge it every night) or for playing golf.

IMHO, the current state of EV batteries is indicative of an industry that’s ahead of it’s time. Check back in 10 years or so.

Three questions re EV trucks:

1. What is the average range? Anything less than 500 miles isn’t worth it.

2. What is a charging time? Any time more than 1/2 hour is not worth it.

3. How does an EV truck compare with a standard diesel truck? Truck cost? Truck lifetime? Operating costs? Insurance cost? Etc.

Supposedly this truck has a 500 mile range…..but I am guessing that’s with an empty truck.

How much for a heavy load? Far less. In the cold? 3/4 to half of that.

I own an EV and this makes no sense to me.

Recharging an EV is but one of the myriad of problems associated with this lunacy.

The battery pack in the New Hummer H3 weighs over 3,000 pounds to move a 9,000 pound vehicle. The gross vehicle weight of a typical tractor-trailer combination is 20-40 tons or so. How much cargo weight will have to be forfeited in order to allow for the added weight of the battery pack, which will surely be several tons. To say nothing of the increased costs due to the lower cargo capacity per trip.

The new Tesla tractor trailer has an announced all up Gross Vehicle Weight Rating of 82,000 pounds. How much of this weight will be for the battery pack?

An EV typically weighs 40% more than a comparable ICE vehicle, due to the weight of the battery pack. Don’t forget to factor in the increased wear on tires, infrastructure and roads, bridges, etc., along with the concomitant maintenance needs and further damage to Mother Earth Gaia as a result...

Much of our governing elites are beyond belief stupid and reckless. But then again, I have yet to factor in corrupt, mendacious and tyrannically obsessed with control.

The first commercial deployment of electric semis is definitely going to be short range hauls. Reduce battery pack weight, increase benefit of regenerative braking, ease of maintenance and charging back at base every night, more points to environmental impact of eliminating emissions where short-haul carriage is concentrated.

Long range needs a few more years of increasing battery energy density, decreased charging times, and expanding charging infrastructure and EV truck maintenance networks.
