Assuming a standard "fast charge" of 22KW peak (18KW average), if it was discharged to 10%, it would take over nine hours to recharge.Charging bays are already being used by motorhomes.
A diesel generator that fitted in a locker will probably only be 2 to 3 KW, so it'd be running 24 hours a day to catch up.You can extend the range by fitting a large diesel generator in one of the lockers.
But...... it would still extend the range. Maybe only by about half a mile but I am not wrong, am I?A diesel generator that fitted in a locker will probably only be 2 to 3 KW, so it'd be running 24 hours a day to catch up.
Just in case you missed it, I was not being serious.I'm not sure how much the range would be reduced by the extra load of a generator. Might end up with less range as well as less payload.
Yes a Range extender is a very sensible idea, it’s effectively what the BMW i3 and Ford Transit have.Better perhaps:-

As a matter of interest, how much diesel did it use running for 7 hours?As for generators the iveco in my Avatar came with a 10kw Cummins Oman Diesel generator
I have a standard 7kw EVSE and a spare 3kw one with a 16A commando plug so yep I had to give it a go!
Full tank of Red Diesel, ran it for 7 hours and a fully charged car
0 mpg out of the van though
The motorhome originally under discussion claims 1.57 miles to the KWh, so even at the full 10KW (which is fairly unlikely to be sustained for hours) it would take over 17 hours to put 270 miles of range in. That's a fair bit longer than overnight.As for generators the iveco in my Avatar came with a 10kw Cummins Oman Diesel generator

At a guess it probably used around 2l an hour.As a matter of interest, how much diesel did it use running for 7 hours?
That sounds about right. Assume 10KWh per litre in the diesel and maybe 35% efficiency, two litres would give 7KWh, which is what you'd expect to charge batteries at a nominal 10KW.At a guess it probably used around 2l an hour.
I used to have a car with an LPG conversion.as an aside i see steve ( roaming radfords) has just driven his Buzz e van down to gibraltar caught the ferry to morocco got from calais to cadiz in 4 days 1350 mls serious drive with any veh let alone having to charge up in between
. . . . and don't forget the additional drag of the diesel generator you will have to tow behind you.270 miles? Then take off the 20% top of charge (should only charge to 80%!) Then take off the 20% bottom of charge and you have already lost a lot of miles. Then, doing more than 50mph will take off a few more and then you have to find a charger for it! I recon not much more than 150 miles if driven very carefully!
Edit: Just a thought.. Something that size is going to be over 4.25 tonnes, the proposed new weight for non C1 with electric vehicles.
There's a brilliant Youtube on how JCB have converted their standard diesel engine to run on hydrogen. Sir Barling (? is that right) points out why it is good for their vehicles. They go to one place of work, move around the place, then they want refuelling. So the fuelling method is that a big lorry carrying pallets loaded with hydrogen tanks takes them to the building site, or farm, which is the refuelling point for the JCBs. The digger, when it gets low on hydrogen goes to the location where the tanks are, refills, and goes back to ploughing the farm, or digging the trenches or whatever they were doing. That overcomes the issue of lack of refilling stations at the roadside. It doesn't address the issue of the cost of electricity needed to produce the hydrogen though . . .......
It could be the motor caravan manufacturers become the last to switch or jump directly to hydrogen if it ever becomes a thing.
