Its not about flogging the batteries. If they let me accelerate 11-12 times I will save MORE GAS than I will using them to ease up on the throttle at 55mph.
Your just not understanding the efficiencies of these cars. They are MOST efficient while cruising. its the acceleration that is the worst possible time to use the ICE not the cruise.
for acceleration I only need to use the batteries at full power for maybe 15 minutes TOTAL for the whole trip.
they MIGHT last 30 minutes at "cruise" if I was really lucky (probably more like 25 minutes)
in that 15 minutes of acceleration I will save MANY TIMES more gasoline than in the 30 minutes of cruise.
On top of that its even WORSE since now I have to use EVEN MORE fuel in the ICE at the worst possible points in time to ACCELERATE this larger mass of batteries and motor to speed.
with the 0-35 mode the batteries are moving themselves. once AT speed mass is a minor penalty.
its all about the inertia. thats the part your missing.
when your at a stop your fighting inertia. when your cruising inertia is HELPING you.
PLUS by using the ice for acceleration this means I can NOT turn it off at every light I have to leave it running. eating up even MORE fuel.
while the motor will only be used 11-12 minutes for acceleration BECAUSE I CAN DO THIS I actually get to keep the motor off for close to 18 minutes (I will have to time it to nail down more accurate numbers)
each light is 3 minutes of ZERO gas usage plus the coast down time. since I would have the electric motor to get me back to 30 or so I would not have to worry about light timing or anything like that. Light goes red TURN off the ice and coast. Stop wait start up the EV motor to 30mph and then and only then restart the ICE.
there really is no point in using an ev motor to "enhance" cruise especially on a car this small which is already silly efficient at cruise. The gains would be SO SMALL that I am not sure if it would be reliably measurable. Unless I was able to SHUT DOWN the ice at cruise which the setup you describe would NOT permit me to do.
"If it's contribution is minimal when it has been so optimized to maximize motor efficiency and battery energy extraction during cruise,"
thats the part your missing. what you describe is the OPPOSITE of maximizing motor efficiency. your saying use the EV at its LEAST efficient point in the process and use it at the ICE's MOST efficiency point in the process both of which are the OPPOSITE of what you want to do.
you want to use the EV when "IT" is most efficiency IE acceleration and you want to NOT use the ICE when it is LEAST efficient ie Acceleration.
