More FUD. Usually you post real information. What bee is up your bonnet about BEV trucks?
Biggest problem is to maintain the current truck/driver model, where they are driving 8 to 10 hours of the same truck. In that case, we might need upward of 10,000 pounds of batteries. However, there are always shorter hauls where they can decouple the drivers with trucks/trailers, or go with hybrid diesel/EV.
Drivers can only be on duty for 8 hours before being required to take a 30-minute break. They can only drive for 11 hours total before having to take a much longer time off.
EU rules are more restrictive, a minimum of 45 minutes rest every 4.5 hours and a maximum of 9 hours driving per day

A 45 minute break will get you a 90% charge if the supply can provide adequate current. That\'s a slam dunk! The EU also gives a 2 tonne weight extension for BEVs. In the US it\'s only 1 ton.

Drivers can only be on duty for 8 hours before being required to take a 30-minute break. They can only drive for 11 hours total before having to take a much longer time off. In a 30 minute break, charging can restore some 70-80% of the initial range. Call it 75%, so 11 hours of driving can extend to 175% of the initial range. 11 hr x 65 mph = 715 miles requires a vehicle range of over 400 miles. That\'s not a stretch in any way. Tesla is planning 300 and 500 mile versions. I can\'t tell you the weight of those batteries, but Tesla is saying they will not have to give up significantly on the payload capacity, \"less than 1 ton\", according to Musk.

We can only guess. Current Tesla battery is around 1/2 ton for vehicle weight of 3 to 4 tons. A fully loaded semi could weight 20 to 25 tons. I think it would be several tons of batteries.

Read the link I sent. Standard prime movers are being retrofitted (in
under a week!) with electric drive motors and quick-swap batteries. The
trucks aren\'t limited by the geometry or aesthetics of a passenger car,
so standardised interchangable batteries are easily achievable.

The batteries are rented, so the owner just pays for the
power+depreciation. Battery exchange/charging stations are being
installed every few 100km along major highways.

Rechargable. Currently Lithium, but the module form factor is designed
to adapt to likely new chemistries. The important point is the drive
motor and battery fits into the existing motor cavity and fuel tank
locations, so there is no structural modification required.

The conversion cost is equivalent to rebuilding or replacing the diesel,
and the operating cost per kilometre a little over half, and service
costs also significantly reduced.

My tiny Leaf can do around 3 miles per kWh. I don\'t think a fully loaded huge truck can do the same.

I suppose a battery swap might be more useful for a truck than for cars. But there are issues with scheduling. When a truck has a delivery, that delivery has a schedule. You arrive by the time of your dock appointment or you lose it. I would expect battery swaps to be the same way. So an appointment is made in advance and what do we do to make sure we arrive in time for appointments? We arrive early. The whole point of the battery swap is to reduce wasted time charging. So how does it help to have to arrive 15 to 30 minutes early to make sure of meeting the appointment, vs. simply spending 45 minutes to charge?

It\'s hard to imagine a battery swap for trucks that is so rapid that no appointment is needed. But maybe that\'s just the limit of my imagination.

Comparing to fueling up or charging, the battery swap is going to require trained personnel and something that may be a bit on the fancy side to swap out the battery. I don\'t know if that will be a significant factor in the cost of the service or not.

The main issue will likely be the company itself. You are limited to working with one outfit, serving how large an area? They can even fold.

Biggest problem is to maintain the current truck/driver model, where they are driving 8 to 10 hours of the same truck. In that case, we might need upward of 10,000 pounds of batteries. However, there are always shorter hauls where they can decouple the drivers with trucks/trailers, or go with hybrid diesel/EV.

That liter of diesel will get you 2.5 to 3 miles. 10 kWh will get you 5 miles according to Tesla. 100 kWh, 500 miles.

To Ed, It is silly to think they are providing fuel consumption data for anything other than a fully loaded truck. The people they are providing data to aren\'t stupid.

Rechargable. Currently Lithium, but the module form factor is designed
to adapt to likely new chemistries. The important point is the drive
motor and battery fits into the existing motor cavity and fuel tank
locations, so there is no structural modification required.

The conversion cost is equivalent to rebuilding or replacing the diesel,
and the operating cost per kilometre a little over half, and service
costs also significantly reduced.

I suppose a battery swap might be more useful for a truck than for cars. But there are issues with scheduling. When a truck has a delivery, that delivery has a schedule. You arrive by the time of your dock appointment or you lose it. I would expect battery swaps to be the same way. So an appointment is made in advance and what do we do to make sure we arrive in time for appointments? We arrive early. The whole point of the battery swap is to reduce wasted time charging.

The answer is 3 minutes (which took me about 3 seconds to find):

Comparing to fueling up or charging, the battery swap is going to require trained personnel and something that may be a bit on the fancy side to swap out the battery. I don\'t know if that will be a significant factor in the cost of the service or not.

For us imperialist: 4 * 3.78 * 0.62 = 9.37 miles per gal. That\'s pretty good. We used to deal with 5 to 6 mpg for big trucks. 30% of 37.8kWhr (1 gal) for moving is 9.37 miles for 12 kWhr or around 0.8 mile per kWhr.

And electric motors can usually handle quite a lot of extra power short term
Yep, I put a 2hp 28V motor on a go Kart. 2HP = 1492 watts/28V = 53 amps.
But I ran it on 48v and the 250 amp meter pegged on acceleration.
48v x 250 = 12,000 watts. 12,000 / 746 = 16 HP. We could run it a full speed
40mph without any heat problems, but by the time you got to full speed
the current
had dropped way down.
Many years ago some guys from a car magazine tried making a dragster out of a mail jeep and an electric motor, DC commutator I believe. They had a little trouble with the commutator I believe, but the ultimate problem was they used a cog belt drive, and kept shredding the belts! I guess no one tried doing any math to see what the forces would be.

 At one time I took it to a local marina where there were several guys.
One heavy guy got on, he nailed it and took every tooth of my motor
sprocket!
Easy fix, I had on at home. So, ya, torque up the wazoo!

Was it obvious to the designers, from day one,
that this would be the case? Is it simply a power/weight
calculation?

I\'m congenitally leery of simple explanations -
For one thing, it\'s easier to install and control multiple motors.
For maximum performance, you can put one (or more) motor per
wheel, which is hard to do with ICE.


For one thing you are being presumptuous... again. Not very
bright.

Seems all show and no go. 6 years on Youtube and not a single comment,
you can be the first!

When did ICE start meaning Internal Combustion Engine and not In Car Entertainment? Classified ads always said ICE if it had a good stereo.
