For prime-movers doing local delivery type operations then heavy hybridisation, exhaust heat recovery, or full Electrification makes a lot of sense (low average speed, lots of stop starting), but for longer distance inter-city operations then alternate solutions are starting to be developed:

What they should do is fit that with metal wheels. The wheels could fit onto metal "rails". Then put lots of other trailers behind it in some sort of train.

That's crazy talk. It'd need special places to stop. "Stations", or some such nonsense

The trucks could roll onto a flatbed train and then off the other end for long distance work.
Simultaneously charging the truck's batteries. The train could run at 80mph, not 60mph. The hybrid truck would then run onto normal urban roads with kinetic energy reclaim. The driver can drive more as while on the train his hours are not being run up.

some are. But if this takes off it would need a new line from say London to Birmingham and then to the north west and Yorks ina Y configuration. Oh isn't that HS2? They could use HS2 and put the passenger trains back on the WCML and ECML with bottlenecks removed to give similar HS2 journey times as HS2. Then the trucks can run at 150mph on the trains.

Good idea - a couple of problems.
Does the driver stay with the truck?
Does he get paid whilst the truck is on the train?

Of course the driver will get paid. but while on the train it does not clock up against his hours. He can stay in the cab, all they need do is chain down the truck to the rail flatbed. Easy to do, just have hitching points made to the trucks from new.

Inductive Charging is the way forwards. No need for ugly overhead wires.

Is solar panels on the roof of the truck/trailer a stupid idea?

Absolute maximum size - 2.5m x 16.5m = 41.25m2. Let's call it 40m2.
Solar panels give about 1kW per m2 theoretical max, and optimistically about 20% efficiency. So that's 40kw x .2 = 8kW.

Do we think a fully charged Tesla Model S 90kWh battery would power a 38t truck for 11 hours...? It powers a Tesla for a bit over 300 miles, so I think we can guess that's going to be a big fat "no", can't we?

And what would happen at night...? We're also ignoring the fact that the panels would never be pointing the optimum direction.

It might add a bit to the range, on a good day, but not much more than that.

But these could power the ancillaries of the truck leave the main drive batteries for true range.

some trailers spend most of the time sat around, some companies are week day/day drives only, if the coverage and fleet were big enough they could be hooked up together to form some sort of storage grid. or even power the refrigeration unit!

Model 3 Tesla's may be built with Panasonic 180w sollar roof which will give it a staggering 2.2 mile extra range smile

This is all about driving forward technology to gain that extra free resource instead of relying on fossil fuels for future of modern transport.

My company are running a fully electric 7.5t for deliveries in Bristol City Centre, also looking into Solar mats for arctics, not to drive them as such but for powering ancillaries and chill trailers which are generally ran from diesel.

OK, great. What's battery capacity, what's the payload hit, and what's the real-world range?

And, for that, it makes sense - not least because you have most charge at the same time as you have most demand for refrigeration. But, even so, there's still going to have to be battery-backing. How much diesel does a typical refrigerated trailer get through?

I will find out!! I'm not on the technical side, I just sell the dream :-)

At work on campus we have a fleet of Nissan NV200 EV's and golf karts.

I noticed in a motor museum last weekn there was a 7.5 Ton DAF Hybrid that they say is on the roads already - looks like any other DAF truck so you probably wouldnt notice, unless it ran over you when crossing the road and not looking...

Just asked the gents in the know

Its a 7.5t so normal payload of about 3 to 3.5, range is 140kms

So the unladen weight is similar to a Diesel engine 7.5 t ?

It's very easy to overload a 7.5.

Hybrid buses are no problem. Some truck applications like refuse collection as mentioned are ok. General HGV trucks are a bit of a problem as there is not enough regeneration opportunities so you end up lugging a big flat battery around using more fuel .
Wouldn't the range extender model be the optimal solution in that case? No emissions when at a standstill, use the electric motors to pull away and drive then use the fossil fuel engine as a generator once the vehicle is under way?

That's basically how the hybrid London buses work.
