Issues when moving to all electric towcars

Already there are going to be many issues relating to using EV's. Range anxiety, charging point availability etc. This will all be increased when towing a caravan. For example how many charging stations will provide space for the caravan during the charging process? So is it time for Caravan designers to think out of the box?

My suggestion would be to add, the same type battery being used for the car, to the chassis of the caravan connected as at present to the car. This could be charged overnight when on a hook up on site. Also using similar technology, used by motor racing, it should be possible to get a charge, from the rotation of the wheels, much like the dynamo that powered the lights on an old bike. Finally, the roof of the caravan could have a custom made solar panel covering all available solid surfaces ie. around windows etc to add to the charge, There should be minimal changes to the caravan wiring as it virtually already exists.

What do you think?

 Interesting test. Looks like the range of both cars is around 120-130 miles albeit on a flat road. Which kind of confirms that the batteries need 3x nominal capacity to match ICE range on realistic terrains.

Battery capacity has tripled in the last 12 years or so, same again and no need for electrically assisted caravans.

Hoping for further advancements in technology to help us 'heavy caravan' users before too much longer....

Do the tests with a caravan on the hook give at what speed they were testing MPC when towing? as was in my company magazine most high miles per charge were at 30kph solo,when it got to motor way speeds it was a very different story , for every hour of M/way driving it would need 70mins chargeundecided

Government has just announced it is cutting the electric car subsidy to £2500 and limiting the grant to cars under £35000 https://www.bbc.co.uk/news/business-56441639 That won't help the change over to electric cars, especially tow cars!!!

No it won't help, I wonder about the reasoning? Unfortunately we had none of these benefits as we bought a pre-reg. Looks like the car industry is bemused by this move and maybe the prices need to come down?

It seems that it was the Government intention to gradually reduce the subsidy. The lower figure of £35000 and no subsidy above that is interesting as most of the smaller cars I have looked at seem to cost around that figure anyway. Maybe, just maybe, it will encourage manufacturers to revisit their price list? That might not happen because the demand for new electric cars is quite strong coupled with waiting lists for some models. I will have to wait a bit longer before I change!

I am all for cutting the subsidy. If the virtue signallers who drive EV’s are so allegedly concerned with climate change why do they need subsidising? Someone who can afford a £40/50/70k plus car doesn't need subsidising. Most if not all are bought as company purchases with huge tax offset. Or, is it simply driving them for the tax breaks.....

I don't like being called a virtue signaller! wink (That's a new one, I've grown used to derogative comments about owning an EV..)

However, our car is paying for itself now in the savings on fuel costs. I would expect others to find this out for themselves in the future.

I think that should read "derogatory...laughing"

I see the subsidies are for cars under the 35k mark.

So do you drive an EV because of climate concerns or because it runs on relatively cheap untaxed fuel? Straight forward question and You cannot answer ‘both’! Subsidies come out of all of our pockets including the very many who earn below average wages but still pay tax and still pay climate subsidies through their electricity bills. Please explain How is it equitable that poorer people subsidise wealthier people? I am no anti capitalist but i am not in favour of returning to a system such only the wealthy can afford a car. It will end in tears.

I wonder if as you can get quite large discounts when hagling on some higher priced  (or not so high)vehicles it probably means they were making to much profit,to start with ,
