    FFE at 2014 Refuel Track Day

    7/20/14 was the 2014 Refuel event that has electric cars go around the famous Laguna Seca race track with no experience or required instructor. This year it turned out a ton of Model S and Roadsters with a couple of Fits, Leafs, RAV4s, and Fiats but I was the only FFE. Once I got out on the...

    TMS (Termal Management System) on low amp 240v?

    So I have been charging in a secondary garage with 120v for convenience though I do have a 240v charger in the main part of the house. The last two weeks have been quite hot and I noticed that TMS system doesn't run when using 120v. In fact the car just cooks it self in that one car garage...

    Replacing the 12v battery?

    Can I just change the 12v battery as I would any other car battery, I know it keeps some sub systems alive. I am going to replace the battery with a lighter lithium pack. After about 15 minute the car drops to about 70-80ma continuously draw from the 12v battery.

    Long Trip, 120mi

    Focus as home generator

    I have heard of the Leaf guys using their car as a backup generator for the home. Essentially put a 1000w inverter on the 12v system which can support up to 100a from the dc-dc converter. You can then use that power to run a fridge and some lights while just leaving the car in ready to drive...

    Tow charging = DC fast charging

    The FFE has some pretty awesome regen capability. I have read where folks had decent of 2000-3000ft into a valley and can put some substantial power back into the car. So the idea is put a 20k lbs tow strap between a truck and the FEE front tow hook and get pulled around while applying...

    Max Current input

    Does anyone know what the max current is for the FFE input? Can I use a juice box on a 120v 30a circuit and get 3kw? Can I charge on a 208v circuit and get to 6.6kw if it was a 40 amp pilot signal?
