It doesn't matter whether it is a big vehicle or a small one, for every technology there is a limit on range and performances. For EV's you can increase battery capacity, and you then increase the weight of the vehicle, until nearly all the total weight is the battery. For current lithium technologies, that means a range of about 1600 km, but of course such a vehicle is useless. That's why the best EV range in EV's you can buy is about 800 km, and the battery weighs about half the total.
People talk about EV in freight haulage, but that is never going to work for other than inner city courier service.
If you built a diesel vehicle, a 2-person sedan or a heavy haulage truck with fuel capacity half the total weight, the range would exceed something like 20,000 km, taking into account it would get lighter as it goes along.

Careful, MGUY. Non-EV buses can burn just as violently. Just ask Transperth WA, who had at least 14 non-EV buses in their fleet of 474 Mercedes buses destroyed by spontaneous fire. They had a marked habit of burning out completely within minutes, usually totally destroyed long before the fire brigade could get there.
London's experience of 3 buses out of 380 catching fire is pretty bad and not acceptable, but actually looks pretty good compared to Transperth's non-EV fleet.
And, yes, non-EV buses DO burn just as spectacularly as EV buses, because, unlike cars, bus bodies are made of aluminium. Once started, aluminium burns really good. See for example https://www.youtube.com/watch?v=LZhWCjGDFNM

@EnjoyFirefighting If, as you say, a fire station is not staffed (or not staffed 24x7), then it definitely needs a fire alarm. Most of the smaller fire stations in Australia are run by volunteers too. They have a system whereby their home or nominated phones are called, and they proceed first to the station to get their vehicles and equipment.
A smoke alarm is what a building fire alarm actually is. Depending on the building's size, worth, and purpose, it may be domestic-style ceiling smoke detectors with internal beepers, or sophisticated systems incorporating VESDA (air sucking particle chamber detector) with remote monitoring.
Here is Australia, small town police stations are not staffed 24x7 - they may have only one or two policemen, who must have time off to sleep and eat etc, and spend time out and about chasing crime.
But it matters not, really, what the staffing levels are. Fire stations and police stations are infrastructure owned by the State, and must be secure.
I found several German media reports about their fire-station - they all had the same wording.

For the draw limitation claimed in this video, EV chargers located near each other would have to communicate with each other, or this is some current monitoring device that sends "throttle back" instructions to the chargers. I've not heard of such a thing, and that is not how electricity generation works.
When appliances are installed, there has to be installation of sufficient feed capacity. If you are naughty and exceed the capability of the electricity authority's local substation, a simple thing happens - you trip the overload circuit breaker in that substation and everybody gets nothing. That is essential to protect the substation equipment and for safety.
It is no different to installing extra outlets in your house. You can hire an electrician to do that, but he has to calculate the total demand. If the demand exceeds what your switchboard can handle, he has to upgrade that.
If somehow you manage to get planning approval and construct high drain commercial premises in a residential street, and the electricity authority's distribution won't handle it, they just say you get nothing until they have time to upgrade.
In my street, an old area of single level houses, the council has began approving construction of high rise apartments, thus increasing electrical drain by 2000%. The land developer was required to pay the electricity company to construct new substations to meet that demand on time. Existing home owners don't get their electricity rationed. Why should EV chargers be treated any different?
I am not a fan of EV's, but the problem described in this video is a non-problem.
Electricity companies have been coping with locallised large increases in demand since electricity distribution began 120 years ago.

@vincenzodigrande2070 : Teslas are not sold by dealers here. You order one on their website and,, eventually,, a car turns up.
Dealers buying cars themselves and registering them doesn't seem a thing that a dealer would want to do, as it straightaway incurs around 30% depreciation. And there is a precedent. Years ago in Australia, a local manufacturer bought out a car called the Leyland P76. Designed by an incompetent marketing team, It was a big ugly thing powered by a motor nobody wanted, and assembled with poor quality and without any care. So the public refused to buy it. The factory kept churning them out and shipping them to dealers who parked them in nearby vacant lots. Dealers did not buy or register them - they just dumped them in vacant lots. this kept going for months, until a Leyland senior executive flew out from the parent company, shut the whole factory down and sold all the parked unregistered cars as scrap. I remember driving past a dealer and there were hundred and hundreds of unplated P76's quietly rusting away in a nearby lot - and then a few weeks later they were all gone.
There is a lot of conflicting information on EV's. The RAC group, which is one of the biggest car insurers, is actively promoting EV's. Either they don't think fires are much of a problem, or they are secretly planning to raise premiums enormously and make a big profit. Their magazine arrived in my mailbox yesterday. It has statistics on car sales and ownership. It says EV's still only account for 0.4% of cars owned and registered. Looks like, even after several years of sales, EV's are only being bought by early adopters - the famous marketing term for people who will buy anything as long it is new and different.
