Another,
I think this is interesting because it shows our Phevs starting the petrol motor and charging the hv battery and then stopping petrol motor and going into ev mode, and then repeating, as we drive along in parallel mode speed. This is the sawtooth line showing on previous graph.
This test was done with a MUT-III at 1900kgs weight of the Phev.
