SnowStorm Posted March 7, 2015 Report Share Posted March 7, 2015 (edited) The OBDII data lets us read current out of the DC-DC convertor so power used by various things can be determined by switching then ON and OFF. Consider these as "ballpark" values as current out of converter constantly jumps around by up to +/- 4 amps. Will add various items to this post as they get collected. ReadyTo-Run: About 200 watts - nothing else turned on.Outside Lights: Parking/Low Beam/High Beam = 75 / 220 / 363 wattsInside Roof Lights: Insignificant, can't measure, certainly less than 10 wattsHeater Fan: Speeds 1 / 3 / 5 / 7 = 25 / 50 / 130 / 220 wattsSeat Heaters: Both set to '1' = 145 wattsPower Steering: 45 to 110 watts from HVB (not DC-DC). Measured sitting on concrete while turning wheel +/- 1/4 turn at about one cycle per 2 seconds, then 1 cycle per second (the higher reading). Surprised it was so low but expect it could be a lot higher on the road (?) since its powered from the HVB.

SnowStorm Posted March 8, 2015 Author Report Share Posted March 8, 2015 Just added more data and comments to post #1. The power steering showed no average change out of the DC-DC convertor - then I realized it must be powered direct from the HVB. Sure enough, HVB current showed the increase while turning the wheel.

SPL Tech Posted March 8, 2015 Report Share Posted March 8, 2015 What software did you use to gather this data? Quote Link to comment Share on other sites More sharing options...
SnowStorm Posted March 9, 2015 Author Report Share Posted March 9, 2015 What software did you use to gather this data?Please see link in this post. Its quite a lot for free but it has some rough edges. My .csv files come out with semicolons for seperators instead of commas. ;) Quote Link to comment Share on other sites More sharing options...

My .csv files come out with semicolons for seperators instead of commas. ;) I've been playing around with the iPhone version, sending them back debug log files and crash log file to help them find some bugs. Here's some data from the BECM on my Energi Quote Link to comment Share on other sites More sharing options...
Automate Posted March 9, 2015 Report Share Posted March 9, 2015 I'm curious about the A/C power usage. Guess we'll have to wait for the summer for that. Quote Link to comment Share on other sites More sharing options...
SnowStorm Posted March 9, 2015 Author Report Share Posted March 9, 2015 You can see A/C power on the MyView screen if you select Climate/Accesories (or whatever its called). I want to check sometime when its warmer to see if the MyView gauge agrees with OBDII data. Power on MyView can vary from 3kW (after first turn on) down to 300 watts once cooled down with recirc and a relatively high temp setting.

Automate Posted March 9, 2015 Report Share Posted March 9, 2015 (edited) Thanks, I don't actually have a C-Max but rather a 2010 Fusion Hybrid which only shows a bar chart with no scaling for total accessory power. Found this topic interesting. Is the A/C driven by HVB or 12V battery? Edit: I see its on the HVB. Does the AC 300 Watts include the cabin air circulation fan?

Kelleytoons Posted March 9, 2015 Report Share Posted March 9, 2015 AFAIK (others here will tell you right, though), the 12 volt ONLY supplies power to actually turn the car on (all other power being supplied by the HVB). Quote Link to comment Share on other sites More sharing options...
Automate Posted March 10, 2015 Report Share Posted March 10, 2015 (edited) Consider these as "ballpark" values as current out of converter constantly jumps around by up to +/- 4 amps. You also have battery cooling fans in the back and a radiator cooling fan that may be coming on at random times.
