this is just simplification of the working for layman. the actual working of course will be more complicated. but in general, the hybrid system will try to maintain optimum engine rpm as much as possible, i.e this during slow speed, excess rpm it use to charge the battery. during high speed if battery is sufficient, it may just use to electric motor as supplement so the engine rpm maintains at the efficient range. only during rare case where the battery almost depletes and at very high load that it will fully use the engine 100% to drive the wheel.

can. electric motor can run at variable speed and rotation that matches the wheel rpm, early ev dun have reducer gb, and there are 2 motor driving the front (or back) wheel on each side. but motor running at that speed (low speed) is not efficient, that why the reduce gb is introduce so that the motor can around the range of rpm it most efficient at.
