Not to sharp on mechanics huh?
Back in the old days of early automobiles manufacturers where making starters (motors) and generators (power sources) all in one unit. These were mounted on the front of the engine and powered by the engine crankshaft during operation.
The same principle can be applied to an electric motor (engine). You expend a portion of engine output to generate electricity to charge the batteries. It would be impossible to achieve a full charge this way but could supplement electrical charge enough to increase range.
like I said though, the problem is heat. Heat already is a big problem with EV and adding in extra heat from the charging process is likely a deal breaker for this concept. I just wonder if these so called engineers pushing the EV narrative have ever even considered this possibility? I have little faith in that at this juncture as I view the whole initiative suspect.
WHAT? None of this makes any sense.
