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?

Unfortunately for me that journey can take between 8 to 10 hours. I have never yet done it without hold ups. M6, M1, M25. You really are lucky if you only get 1 hold up.

I feel your pain on the motorway issues. Ironically, for an EV, traffic helps range. Unlike with an ICE, where travelling in lower than top gear and outside the optimum rev  range hits performance and economy, running at a lower speed has 0 impact on efficiency of the drive train, and so the improvements in total efficiency resulting from reduced drag become far more apparent. I.e. slower is better, and traffic extends your range… 

But it’s still _no fun_ sitting in crappy traffic! 

And it’s still true that EVs are not yet for everyone, especially towing with an EV. I must be in a tiny minority of folk who tow at all with an EV, let alone a full sized caravan. Early adopter fun!

500 miles solo is becoming real on very high end EVs today, that would equate to over 200 miles towing. It will be here a loooong time before hydrogen for personal vehicles (if that ever happens - my bet is it won’t, it’s just too costly).

How much over 200. We will just have to hope the high end become affordable before we get rid of our ice vehicles. Incidentally would it be rude of me to ask how much your vehicle cost. Because from what I read the EV’s with a good range are very expensive. Every credit to you though for being so organised.

Just as with an ICE, towing efficiency with a large caravan (and hence range) on an EV is a bit better than 1/2 of solo. So if you can get 500 miles on a charge sole, that translates to between 250 and 280 towing (at a rough guess).  

Mine is not cheap, but its targeted at the premium performance saloon market, (400hp, 600NM torque), so at 58K list its an expensive car, but targeted at Volvo V60 T8, Audi S5, BMW 340i Msport Xdrive type market - so on a par price wise with the ICE competition. 

But as a company car (arround £650 a month) its 1/20th of the cost of most of those in tax. 

I am very lucky to be able to drive it, but its also a great way to tow a caravan.

Yesterday I received an invite to test drive the new Audi Q4.  
The issues for me, regarding the thread title, are-The cost of purchasing, ability and cost of installing a charger at home where car is not “alongside” the house, the range.

I will be taking the test drive out of interest but , as things are currently, can’t see me going the EV route for some time.

How people who do not have the ability park “at home” will manage I don’t know, but then maybe the promised investment will remedy this and the other known and inevitable future problems.

As time moves on I think we’ll see the popularity in EV’s grow & ICE drop thus prompting the ‘fuel’ stations to switch more & more to EV charging points. I don’t have a diesel pump at my home yet I get by👍🏻. In around 10yrs time we’ll be taking minutes to supply a full charge of that there is no doubt. At the mo it’s supply & demand.

When EVs as our ICE can get me about 250 miles with a caravan on the hook without the need to refuel then it may be with looking at one, but certainly not at the prices now being charged,  even to lease one ,I would expect  a replacement new batt before buying o a used one ;company car at £650 per monthsurprised

At this time the UK Gov is encouraging.? .the use of EVs if I remember they did the same for Diesel enginesundecided

By then I doubt many on here will be bothered   it will be Down to those now working who will be bemoaning the cost of everythingcool

With that in mind the best advice I can give is whatever the goverrnment of the day advise, do the opposite.

I doubt it JV kids these days will be happy to see the back of planet destroying fossil fuel vehicles. You forget the children of today are more thoughtful than previous generations & a darn sight smarter too👍🏻
