Yes, possible and in the prototype stage, so very expensive.
This also does not address the different legalities of different countries, provinces, states, etc.
Here in the US, some states get really picky about what is powered and how it is taxed. A trailer is considered unpowered, so might have to be plated as a vehicle if able to move on its own.
Trailers with sensors to help prevent jackknifes, regenerative braking, and battery storage could make a lot of sense in the right use cases.
But the utility has to outweigh the loss in cargo capacity (for commercial cargo vehicles), added complexity, costs, and weight.
If the towing vehicle, say a Tesla Semi, has a very heavy and large battery, why add another to the trailer to take from cargo capacity? It also drives up the cost of the trailer... and there are more trailers than trucks, so you would need to have even more electronics (chips, in short supply), more electric motors, and more batteries (don't have enough of those either), which means less EV trucks, cars, etc, because those things are going into trailers.
Now, once the majority of the fleet has been updated to EV, then there might be extra manufacturing capacity and components that this becomes more feasible... and probably more likely, as all of these companies that have ramped up to produce the chips, motors, batteries for EVs see their demand go from a volume of replacing the fleet to a maintenance volume of just keeping up with incremental growth and replacing worn out vehicles. This is when I see things like powered trailers becoming practical and affordable.
And maybe even the laws/regulation for such would have caught up.
