Living in southern California, I have to drive over a lot of hills. I asked this in existing threads, but I have not gotten any answers to it.
Is there any good trick anyone has found to keep the C-Max from trying to charge the battery when climbing a long hill?
On many trip I have to go over 2 mountain passes with close to 1,000 feet of climb and then descend.I have tried getting to the hill with both high and low charge in the HV battery, but once on the climb, it seems to ALWAYS work the IC engine very hard and charge the battery when it should be using electric to help climb the hill and deplete the battery. I want to get to the top of the hill with the lowest possible battery, because I know I will be on the down hill for a while and every time now it tops up the battery at only half way down and I have to start using engine or friction braking to maintain legal speed. When I do not have traffic around me, I have been able to use a sort of pulse and glide to make it use ICE + EV to give me acceleration up the hill, but it still goes into charge, slowing the car during the uphill glide. I want free wheel glide and battery assist to climb the hill. It would be nice to have a button like the Chevy Volt to make it use battery power. Having it only use the throttle seems to work very well on ost flatter roads, but it really does not understand steeper hills very well at all.
I am still on my 6th tank since I bought the car. I get well over 400 miles and the gauge is still between 1/8 and 1/4 when I fill up. Early in the tank the distance to empty added to my trip since fill adds up to just over 600 miles, but it falls to about 550 or so when I get to 1/4 tank remaining. The fuel consumed is low by 7%, meaning I am actually burning 7% more than the screen says, assuming the 2 gas stations I use are accurate, and since they both agreed, I tend to trust that more then the dash readout. My current trip is just over 46 mpg, factor in the 7% more fuel actually burned and I am at a real 43 mpg for over 250 miles of mixed highway / city driving. Not too bad, but I think I could do even better with a good hill technique.
