Experimental data

Re: Experimental data
Yes but only because the control computers are using the engine power to generate a charge for the battery. My first measurement shows the ICE is producing about 15,000 watts, ~20 hp. It feeds about 12,000 watts, 16 hp, of electrical energy to the battery. So the remaining 3,000 watts is 'heat' primarily heating MG2 although MG1 is probably taking 600 watts and the inverters another 600 watts.
The accelerator has two control computers before reaching the throttle. When I hold the accelerator pedal to the floor, it adjusts potentiometers that connect to the hybrid vehicle control computer. The hybrid vehicle control computer knows the settings of the gear shifter and operates the motor generators and sends a command for "x" RPM to the engine control computer. The engine control computer manages the throttle to achieve that rpm.
I have not done this yet but others report that with the brake on and the accelerator floored, the battery will charge to 80% and the ICE will slow down and stop. This is called 'forced charging.' However, I need to do this to measure the current into MG2 and how long it takes to fully charge the battery.
