Li-ion battery life
Posted 31 October 2012 - 06:22 AM
So what does this have to do with the C-MAX Energi? The C-Max has a separate cooling system for the batteries to try and keep them at optimal temp. This is true for the all electric Focus too. Whether or not it works remains to be seen, but it is clear Ford is making every attempt to create a quality product. See the whole presentation at the link below.

Why did Ford not go with liquid cooling for the C-Max as well as the Focus? I would guess the additional space, weight, and cost. Possibly also the demands in a plug-in hybrid are not as likely to result in thermal extremes as in a true BEV one.
My personal analysis (planning on owning this vehicle a long time) include an assumption of replacing the battery once somewhere around nine years/100K out, outside of warranty period. I also assume that battery costs have dropped to $250/kWh by then (which is what most experts seem to predict but who knows?). Liquid cooled might extend that a year or so but not out the 17 plus years the car should last so there would still be one replacement per vehicle lifetime.
Active cooling though seems essential.

Meanwhile I hope that Don is right. I won't replace until I have to but I hope by then the technology has improved, hopefully with greater energy density and power for less cost, taking up less room yet going a bit farther with more kick ... but we have no way to know. These unknowns regarding the battery lifetime and replacement cost are part of why I have preferred the C-Max approach for myself, over a full BEV and even the Volt. This battery is big enough to handle my typical daily needs on all electric (if just) and small enough that replacement if when it happens is less likely to be to big a hit.
