It got gears but has infinite gear ratios like a cvt? It has 2 electric motors inside it, but one of them is the cars alternator? The whole thing sounds like magic.

ELI5:
– output (wheel) rpm needs to match your vehicle speed which can vary across a wide range
– but gas engines run best at 1 particular rpm.
– whereas an electric motors run fine across a wide range of rpm
E-cvt has a fixed set of gears connected such that:
Electric motor rpm + gas engine rpm = output rpm
This lets us run the gas engine at its particular rpm and still have a wide range of output rpm by having the electric motor rpm make up the difference.
Then, add on more details, such as how each input/output has its own gear ratio, which just adds a fixed multiplier on each rpm. And use 2 electric motors instead of 1, for even more flexibility. But the bottom line is that instead of changing gears, we just change the speed of the electric motor(s).
