An active pantograph on top of each truck stays in contact with the overhead line, continually charging an onboard hybrid system as long as the semi runs under the wires.
When the trucks aren't running on electricity, their hybrid powertrain reverts to its combustion engine, using either conventional diesel fuel or compressed natural gas.
The engine switches on automatically when the trucks disconnect from the catenary system to pass another vehicle or change lanes, or simply when the system doesn't need further charging.
It also allows the trucks to leave the lane equipped with the overhead wires.
The difference between the two articles on electrified lorries is that the first one being trialled in the UK relies on a small battery to complete the start and finish of the journey, whereas the Siemens example use a traditional ICE, which offers considerably more flexibility - that seems more realistic!!
Not sure where this belongs so I'll slide it in here.
20% of California electric vehicles owners have switched back to gasoline vehicles, complaining that it takes to long to charge and they get to little mileage from a charge.
I saw an absolutely beautiful Porsche parked out front of Market Village. As I walked by the owner was getting out. I said "rot suay" with thumbs up. She actually stopped me to tell me it was her new electric car.
I didn't ask the cost
Never underestimate the power of stupid people in large groups.

Porsche Taycan Beats Electric Cross-Country Cannonball Record
"Last week, Conner crossed the US in a Porsche Taycan 4S in just 44 hours and 25 minutes."
That's for about 4500km including charging, it's possible because cars like that can charge from 20% to 80% in about 20 minutes on a fast charger, so with a 20 minute break every couple of hundred km, you can drive for ever.

Interesting must have been close to the speed limit in some states or even over. Mosts test like that are specially set for the test. Lets see him do it in an average road car sold to the general public. Also he drove for 44 hours and 25 minutes. I find that hard to believe as well.
Woke up this morning breathing that's a good start to the day.

The previous record was 45 hours 16 minutes in a Tesla 3.

As it says in the article:
we don't recommend attempting your own Cannonball Run record as there are many potential safety concerns involved, not to mention you'd be breaking the law.

I did not bother to read the article, it was obviously a test set up, maybe some revelance in development, but when in can be done in a ordinary car using charging points available that would be a test that proves they are a feasible buy if the price comes down and a longer battery life. I run a mobility scooter and the mileage it can do is variable, dependant on road conditions, hills draw more energy, the load it is carrying. I will have a bet that all the mileages claimed by electric cars does not account for any of that.

....the mileage it can do is variable, dependant on road conditions, hills draw more energy, the load it is carrying.....
That's the same for internal combustion vehicles which has a relevance because new emission laws being planned for introduction in 2025 in many markets require vehicles to meet stringent requirements in all driving conditions including heavy acceleration.
That will make it very difficult to make a high performance pure internal combustion engine car and that's why many automotive companies are coming out with these announcements that they're going fully electric from that point on.

It will be interesting to see how this develops.
The one thing that puzzles me is the lithium mining and processing and the disposal of old batteries will have a big effect on the global warming.
Hydrogen is a common product easier to gather, why is there not a big push to develop this, there are a few cars that do have this and I have never heard of problems.

They all talk "Zero Emissions", but it's a crock - what are the emissions or effects on the environment through production (and disposal of batteries), Lithium mining as Lindosfan states? How is the electricity to be produced? In the UK, we're looking at a massive overhaul of infrastructure - what impact does that have?
Why are we not looking more towards fueling the existing combustion engine with "environmentally friendly" biofuels or the likes of HVO (http://www.jrf.org.uk/publications/browse)? Minimal impact to existing engines or infrastructure.... They don't just fuel 50cc's either!!: -
There are so many issues here it’s difficult to know where to start, but top of most people’s agenda is the realization that global warming is accepted by the majority as the number one risk that’s needs to be tackled now - if not then the world is heading towards disaster. Everything else seems secondary, so whilst there are undeniable consequences from changing over to electric vehicles, lithium and other minerals required for batteries are of secondary importance - this may prove to be short-sighted in the longer term. Over time, hydrogen may become a bigger player, but at the moment it’s very much second fiddle to electric vehicles.
I think the only real problem with Hydrogen is that the infrastructure hasn't been developed. If a network of production and distribution facilities had been put into place starting from about ten years ago, it might now look more viable.
Electricity for battery cars is already manufactured and delivered worldwide and the facilities already exist.

"There is definitely enough energy and the grid can cope easily,” he explains. “The growth in renewable energy means this is not static and smart metering will make this more efficient. For example, the growth in wind power from the extra offshore wind farms being developed will adequately meet the future demand for electrifying transport – an extra 100 terrawatt hours from our current 300 terrawatt hours consumed.
Depending on how solar technology develops in the future, the problem of charging will be overcome. Ideally, solar power will constantly charge the battery 'on the move'. Some inroads have been made with solar powered cars but there's still a long way to go.
