From the below graph we can see that at 45mph the NHW11 requires ~10 hp. If the running draw is 1 hp including all losses, that's 10% just like a regular ICE car.

The graham scanner reports the HV battey is supplying 1.5 to 2.5 amps of ~270 Volts to the DC-DC converter to run the basic requirements. that's .54 to .9 horsepower before calculating in the generator and battery losses, which means that the engine has to come up with a bit more than that accumulated power somewhere in the driving cycle. Since that draw is constant during ready mode, that's quite a few of watts all told.
