An exciting new innovation from Alko is an electric 48-volt drive integrated in the chassis of trailers and caravans
The range of electric towing vehicles is greatly reduced when combined with a traditional caravan or trailer in some cases by up to 70%. This would mean a reduction in range from an average of 500 km to only about 100-150 km. Alko's exciting solution is an electric 48-volt drive integrated in the trailer chassis. This means a higher range can be supported, and there are more advantages

Less Emissions, More Range
The 48-volt drive integrated in the trailer chassis actively supports the towing vehicle and thereby increases the range regardless of whether it is a classic combustion or electric vehicle.
X-TRA Charge Mode Active Loading
When braking, the brake/overrun energy can be recovered by a recuperation function in X-TRA Charge Mode, which actively charges the batteries installed in the trailer chassis. This energy can be used to support the towing vehicle, thereby reducing fuel consumption.
The recuperation charging system also serves as a braking function, downhill braking when driving over mountain passes is more comfortable and more wear-resistant.
Anti-Snaking System Torque Vectoring
An automated and sensor-supported electronic control system transmits safety data to the electric drive, which powers or decelerates the wheels individually. Sensors guarantee the shortest, situation-specific reaction times. This means that the caravan/trailer can be stabilised in dangerous situations without any action on the part of the driver. In addition, other factors such as the loading condition and environmental influences are taken into account in the analysis.
Trailer Park View Assist
Camera systems and intelligent sensors enable easy parking of the trailer or caravan.
A manoeuvring aid is integrated into the smart electric drive negating the need for separate motormovers.
A refrigerator, stove, air conditioning system, entertainment system and much more can be operated self-sufficiently by the energy storage unit.
The system can be charged by plugging into mains power sources, in addition to the recuperation function whilst driving,
Smart additional functions Connectivity
In addition, the trailer features anti-theft protection by activating an electric immobiliser, GPS tracking for location, and a readout of the trailer / chassis mileage
Actually weight is where electric cars score heavily. The car's batteries make them heavier than the petrol or diesel versions.
It is an interesting development though and I can see it working for a trailer which is frequently used. For a caravan, used say 4 or 5 times a year, would be very expensive putting them beyond the reach of most caravanners.
Of course, you could add a steering wheel and not bother with the car.
I predicted this would happen 2 years ago when i saw it on a HGV trailer at the commercial vehicle show, To be fair i think its a american idea and i havent heard of it being fitted to any uk trailers, we have a fleet size of 16000 trailers and it's not on any of ours
legislation minefield !!!! The trailer, being powered , would fall into the category of being a mechanically powered vehicle , but yet is not intended or adapted to carry people.....so s not a conveyance ......
I wouldn't like to sort out the legislation for it to be able to be used on UK roads ..

The battery weight would impact upon the already pathetic user payload allowance on most caravans.
I would suspect this is not intended to be built on existing chassis, but purpose built. Legislation could be changed to accept modern technology.
I foresee the wiring between car and caravan will put the car in control of power to the caravan wheels. Yes this would create an entirely different class of vehicle necessitating driver training. But that is progress, perhaps as revolutionary as abandoning the sedan chair?
I would have thought a better idea than a powered caravan would be to carry an additional battery pack in a conventional caravan designed to carry the extra weight which could then be plugged into the car to supplement the car battery capacity.
Battery Suv the size of a Range Rover. Twin axle caravan just within the max legal size. Enough battery pack to take it 700miles. Should get all that under the 8.25tonne combined MAM limit. By this time pitches will include charging point. The future for well heeled caravanners. Whats not to like?
I would think that a sophisticated control system using the linear movement (displacement, rate of displacement and force) of the hitch on the caravan (currently used to apply the brakes on the caravan) could be easily designed and matched to the specific outfit (car+caravan). The caravan brakes could be electrically applied by the same control system. Reversing is already signalled to the caravan from the car.
Electric brakes are not currently permitted in Europe but are used extensively in North America.
my wifes Range Rover is due to be replaced this year and we are enquiring as to the possibility of borrowing a TESLA X fitted with a tow bar to try out towing our Caravan once we can all get out properly...We had plans to purchase a new motorhome this summer and tour Europe but I dont think that will happen for a couple of years now so we will keep our caravan for the time being. I have seen videos on you tube of a TESLA X towing a large boat for several hundred miles on a charge. We dont tend to use our car once on site and rely on cycles we take with us so it would be ideal if we could use and extrications cr to tow to site then just leave it plugged in for use on those rainy days or journeys further afield ...
