Haven't posted for a while but I got my $550 check in the mail today.

I got my best mileage on the leg to work today: 53.7 mpg for a distance of about 25.4 miles! I have 2100+ miles on the C-Max now. My tires are inflated to 41 psi and the temperature this morning was around 49-51 deg F. I just inflated the tire pressure to 41 psi last Friday so I'm not sure if that plays a part in the improve mileage or not. Previous tire pressure was in the range 30-36 psi. This leg of the commute consisted of about 55% city, and 50% hwy and contains small rolling terrain (both in city and hwy). Max speed in city/back-roads was about 50mph and max speed on hwy was 65mph. I would estimate 50% of the speed on the hwy was around 55-62 mph with. I don't cruise at 65mph however. I will drop it back down to 62mph to get into the EV zone when I'm at a flat or down-sloping portion of the hwy. When the engine kicks in, I bring the speed back up to 65mph to recharge the battery. However, I think my home is at a higher elevation than my work, so that maybe one reason why the leg home is normally less fuel efficient than the leg to work. I normally get about 44 mpg on the leg to home.

PT, I think they look very nice. I like how you cut it to precisely mate with the grill. One suggestion I have is to enhance it with a sliding plate mechanism to control the amount of airflow to pass thru.

I'm still here! The world is still here! My C-Max is still here!!! :happy feet:

Yeah I can't link to the photos either. It was working prior to the site attack the other day.

Thanks for the link. Seems like a sophisticated BMS is required to carefullly charge the Li-ion batteries as well as the way the battery cells are laid out and whatever electronics/connectors that are part of that battery system so that it can properly charge each cells.

I remember reading in this forum as well as in the User's Manual that the C-Max will occassionally do some sort of resetting (not sure if that's the right word) of the Li-Ion battery system. I was doing some research on Li-Ion batteries and ran across this site... http://batteryuniversity.com/learn/article/equalizing_charge I wonder if that's what's going on during that phase.

I googled on this topic and there are actually companies out there (since 2007) that have been converting Prii to plug-in (even before there were a plug-in Prius) as well as Ford Escape hybrids. I'm sure there are some pretty bright people who knows what they're doing.

Yeah, heard this on the radio today on way to work. No mention of C-Max however. Wonder how the C-Max did.

I noticed that sometimes when I get home, my C-Max battery is pretty low on charge (maybe 1/5 or 1/4 charged). I was thinking it would be nice to charge that battery up over night. But I'm not interested in a bigger battery like the Energi. I simply want the Hybrid's battery to get charged. What would it take to accomplish this? Would it be possible to do it w/ a portable solar cell so I can set it up at work? What I am thinking of is some sort of portable unit with a power cord where on one end has a quick-disconnect and on the other end, connects to the Hybrid's battery so that this cord can stay inside the car and remains connected to the battery for easy connect/disconnect. Then, portable unit that can be connected to the wall or to a portable solar cell panel. Sort of like those battery tender devices but capable of delivering enough amperage or wattage (?) to charge the high-voltage battery in the Hybrid. Thoughts? Referrals? Links? Thanks!

But if I reset Trip 1 as soon as the car is started and prior to driving, shouldn't Trip 1 and the "Trip Summary" be the same? And why would Regen miles be a factor in determining avg. MPG? And if they are factor, then how do they affect MPG calculations? EDIT: Looking more closely at the data provided from the pictures, Trip 1 shows: 26.8 mi using 0.50 gallon. Trip Summary shows: 26.5 mi using 0.4 gallon. And now I remember. You are correct, RedLdr1. I forgot that I had dropped off my daughter at school in the morning on the way to work. So that explains the discreprancy. So my Trip Summary actually shows only the trip from my daughter's school to my work. Where as Trip 1 shows the data from my house to my work. Thanks for clearing that up!!!

Then what is the avg MPG that is shown as "Trip Summary" at the end of the trip when you shut down the car? Because that is different from all four numbers you listed. For me, Trip 1 says A, Trip 2 says B, Lifetime says C, and 4th average says D. And then there is this "Trip Summary" that is displayed when the car shut down. And this "Trip Summary" is different from all those. I upload some pictures but for some reason I can link them here. But if you look at my porfolio under my user id you will see pictures labled "Trip1 Summary" and "Trip Summary". Before I left the house, I reset Trip 1. By the time I get to work, the picture "Trip1 Summary" shows my mileage info for Trip 1. Then I shut down the car, the picture "Trip Summary" shows that information.
