Anyone use OpenXC?

Has anyone used Ford's OpenXC with the FFE? I was wondering if it gave any really worthwhile information...

Re: What acceleration curve is most efficient?

Faster acceleration means higher motor current. Electrical power increases with the square of the current P=I^2 * R. So you will have more power turning into heat with higher acceleration. Motor resistances are generally small but it's not negligible.

Re: Towed Home after Batt Drained

It's unfortunate but estimating remaining range is a horribly tricky thing to do since Wh/mi varies greatly with even slight changes in grade, speed, temperature and driving style. For all the flak that the "Guess-o-meter" gets I find it relatively accurate considering the difficult nature of the pr...

Re: Max Current input

Most 30A rated units are really 30A peak and continuously draw something less than that (27A sounds reasonable). At home you probably have a 240V circuit so 240x27=6480W. Public charge stations with 208 will have 208x27=5616W. What is your continuous current for home charging? Your numbers are not s...

Re: How-to Evaluate Battery Health at Dealer

If they took care of the battery then I wouldn't worry too much about capacity loss in a year. I'd ask lots of questions about how they treated the vehicle on the lot (did they keep the battery topped up, etc.) and when and how the recalls were applied. The biggest concern would be if the battery ev...

Re: $6,000 Cash Back on 2014 Focus Electric

$10750 incentive is the current lease deal. I'm in 15101 and just leased a FFE from Shults Ford in Wexford. They worked what I thought was a very fair deal. The dealer basically gets a flat fee for these so they are flexible in the price. There was zero stock available so I had mine factory ordered....

Thanks,

Where are you at in PA? I just leased near Pittsburgh and had a good dealer experience. I'd be happy to refer my salesperson. I went with the 10,750 off lease and they worked me a nice deal.

Re: What are you using for a charging station?

Anybody know the insides of these thing? Modifying an existing EVSE is probably not a good idea. But the key thing to check is the relay (or contactor) rating. Then I'd also check any fuses/breakers and wire gauges. If it was designed for 16A then it's unlikely that any of the critical internal com...
