let me also point out an apparent discrepancy here (not the only discrepancy I have seen), even though this is probably the wrong thread
from seconds 335 to 355 you are indicating an increase in speed from maybe 43 mph to 49 mph. At the same time you are indicating the ICE wattage going from a peak of ~13.5kw down to ~10kw. The battery isn't doing anything terribly interesting either at that time, so I have a strong suspicion that you are doing some "double booking" when calculating ICE power. at 355 you are taking something over 10hp from the driveline to generate about 10hp with mg2 to pump ~7hp (conditioning efficiency of 70% prior to mechanical conversion?) into mg1. Meanwhile speed increased and ICE decreased. It doesn't seem to add up.
