Serious Question: Why can’t we just have towable generators so EVs can go from an electric car to a Plugin Hybrid for road trips?

Lets work through some back-of-the-napkin math here.

Lets say the average speed you’re looking to take on your road trip is 50MPH. For that discharge rate you’d need to be able to charge at 50MPH to keep up. That would put you at a charging requirement of 50kw.

Here is a picture of a 50kw towable generator:

This isn’t even any of the additional gear needed for DC rectification and power management needed to interface with NACS or CCS.

and seems like a very easy solution to range anxiety.

You can see why this idea doesn’t really work then.
