I worked with this company on an amazing series-hybrid system that uses a more conventional engine, but it's performance is amazing: https://www.obrist.at/powertrain/ https://youtu.be/cuxR5qy4yu4
Their demonstrator is using a Tesla Model 3. Probably the first Tesla to ever have a gas tank! I have to admit, when I first heard what they were trying to do, I was pretty pessimistic, but their system is a great stop-gap and will make it possible to get more EVs out there for lower cost, sooner. Even if we wanted to make the global fleet all-electric, there just isn't enough materials to make all the batteries for full-electric cars. But if each one uses only a small pack which covers > 75% of the driving, it means you can make a LOT more cars, and you also don't have the chicken-and-egg DCFC charging network issue.
