acdii Report post Posted January 17, 2014 The biggest difference I see between the two is Gen1 can cruise neutral, no charge/discharge on the HVB, but the Gen2 is Very Very difficult to get into that stage, I have achieved it on occasion and saw 50+ on the instant, but any little bump, anything that could get you to move a fraction on the pedal and it was gone. The other note on this is you just can't maintain a steady speed doing this, you will slow down. (unless going downhill, and then you speed up like crazy). What this tells me is the ICE is putting out a lot more torque to the MG1 so it is always putting out power for either the traction motor or to the HVB or both. If you notice on the Gen1, the battery levels remain constant at anything over 45 MPH, which on mine was at 50% SOC on the dash. The only time this was not true was when it was in a conditioning mode, then it fully charged the HVB and the ICE ran 100% of the time. This new one doesn't do that, it charges similar to the Toyota HSD where it almost always went to full when above 42 MPH. When I go down certain roads that are horrible for any EV, I usually wind up with a full SOC, instant hovers around 40(higher in summer), and there is always a charge symbol on the battery. According to the PDF linked above, at this point the ICE should be spinning MG1, with MG2 providing the power to the wheels. Looking at the gauges provided, it does appear to be doing just that. SOC does not change, yet the ICE is always charging. When accelerating, or higher demand like climbing a grade, then ICE and MG2 are combined to propel the car. That is how I see it working. 1 hybridbear reacted to this Quote Share this post Link to post Share on other sites
