I think it has something to do with the hv battery being less then < 30%. Can you check or translate what they are trying to say. We can edit it later.
You are right. It says so in the graph. I did not see that first. But it doesn't change the way I look at it: in serial mode, engine RPM is independent of vehicle speed and so is (within limits) engine output in terms of power and torque.
The document is a bit confusing. First, there are two tables, which I have combined into a single picture:
If you take into account tire size and gear ratios you can translate speeds into e-motor RPMs and thus torques into kWs. What the first table tells you is that with SOC>30% the e-motors can deliver 120 kW max (as of 55 km/h).
The second table table tells you that with SOC<30% the amount of torque at 55 km/h is half of what it is at SOC>30%. This would translate into max 60 kW. This suggests that with SOC<30% no power is drawn from the battery, only from the generator.
But in the text it says that at SOC<20% support from the battery is reduced and you will have max 60 kW / 135 Nm at 65 km/h, all coming from the generator. From the text and my own experience, I think the captions for the tables are wrong. I think the first table is for SOC>20% and the second for SOC<20% (Turtle mode).
