SPL Tech Posted January 1, 2015 Report Share Posted January 1, 2015 So theoretically the blue EV meter on the Engage would show the output power of the electric motor. But at times I have noticed that the EV meter will climb 1 - 5 bars (so about 1 - 3% max output) without the vehicle moving and without my foot on the gas peddle. Sometimes it happens when I turn the AC at first. Other times it happens randomly.This leads me to believe that the EV gauge is not actually displaying the output of MG1, but rather the current draw on the HV battery which the gauge just extrapolates to output power on the display. Any ideas? Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted January 1, 2015 Report Share Posted January 1, 2015 (edited) I believe the 2014 manual to be correct. The 2013 manual is likely in error. This would mean the metering is at the crankshaft for ICE and HVB for EV. From the Owner's Manual: 2014 ManualEnlightenEnlighten displays power demand in addition to the typical information and options from Inform. The Instantaneous Fuel Economy gauge will be displayed by default. When the vehicle is operating on battery power only with the engine off, EV is displayed EngageEngage replaces the power demand gauge from Enlighten with separate gauges for engine power and high voltage battery power. The engine power gauge fill is white and the high voltage battery power gauge fill is blue. When the vehicle is operating on battery power only with the engine off, EV is displayed. 2013 ManualEnlighten — Enlighten displays power demand in addition to the typical information and options from Inform.

drdiesel1 Posted January 1, 2015 Report Share Posted January 1, 2015 Use of the AC compressor will cause the gauge to read. Same as running the defroster.On the Energi, it reads when the coolant heater element is in use also. Quote Link to comment Share on other sites More sharing options...
SPL Tech Posted January 2, 2015 Author Report Share Posted January 2, 2015 (edited) So then it is measuring current consumption and not output then. That implies that the gauge may be of limited accuracy as I assume the gauge assumes the power consumption of the motor is linear, or at least logarithmic, with the load. But in reality, that is never true. For example, as electric motors get hot, their power consumption changes relative to when they are cold. A motor might need 7kW to produce 5hp when hot and maybe 6.2kW when cold (rough example). I suspect the gauge does not account for things like this.

drdiesel1 Posted January 2, 2015 Report Share Posted January 2, 2015 (edited) I was actually referring] to the Energy Use gauge that my NRG has......Sorry! Edited January 2, 2015 by drdiesel1 Quote Link to comment Share on other sites More sharing options...
SPL Tech Posted January 2, 2015 Author Report Share Posted January 2, 2015 hmm, I dont have that gauge. My energy use gauge is fixed with the climate control use gauge, and it looks different. Did you buy your C-Max outside of the USA? Cat Max 1 Quote Link to comment Share on other sites More sharing options...

mtb9153 Posted January 4, 2015 Report Share Posted January 4, 2015 that explains why I've never seen that screen. Energi only drdiesel1 1 Quote Link to comment Share on other sites More sharing options...
