All the hardware is in and mounted. The high voltage cables are all connected except for the BRUSA battery leads (just waiting on some ring terminals). All that remains is finishing the controls. CAN bus work is about 50% done. Getting closer...

Did you use the same contactors for the Brusa and CHAdeMO positive and negative wires? Or, do you have a total of 4 contactors?

Anything out of the ordinary with your car now that you've had the increased charging capability for a couple months now?


Thanks for sharing.

I only used one pair of contactors for Chademo. The Brusa is wired on the always hot side of the contactors. Nothing out of the ordinary has really happened. I used the Chademo fairly often in the winter. When it was cold out, I would routinely come home from work, use my home Chademo, and be full and ready to go in about a half hour. It really made a difference in being able to use heat as much as I wanted. Now that it is summer, I'm not using it as much. A bunch of Chademo chargers just came on line in my area, so I think I'll be using it even more next winter. The only time I use the Brusa is at home combined with my home Chademo. With the ability to use public Chademo chargers, I don't use public level 2 as much.

I am interested in implementing fast charging on my 2013 FFE. I have read through all the posts, but I do not see where you have provided any details(schematics, code, etc). Are you planning on making this information available either as public domain or paid?

I have picked out the necessary messages from the vehicle to control the charging session, and with some software I wrote for the Arduino, the Arduino controls the charging session. I wish Ford would have provided this from the beginning, as it is a really easy process (for an OEM), but alas, I don't think there is very much interest from them.
Does your custom software just monitor the car "passively"? (and control your custom hardware in response)

Or, does it actually "actively" control aspects of the car?
The car's EV-CAN bus is only monitored. I don't send any messages to the car. I use the car's data to control the charging session.

Do you know if the BMS will prevent overcharging of the HVB???

The BECM does do some failure mode checking to ensure excessively highly voltage doesn't occur, but the system is more tailored to regen control than quick charging control. My Arduino ensures cell voltage doesn't exceed 4.15V.

However, when you have the car's onboard charger engaged, the car does monitor for excessive charging power and will shut down over ~10 kW. There is just enough headroom for me to run the car's onboard charger and the Brusa at the same time. But I can't chademo charge and run the onboard charger at the same time, even with keeping cell voltage below 4.15V.

Okay, I just started to log messages, but this is a HUGE step. I admit, I did a dance. :lol:


sefs,

Can you provide some pointers about how you got the CanDue to communicate with the FFE? I just picked a CanDue up, and trying to figure out how to pull down the can messages from the FFE...although there is limited support on the web.

Do you know the exact pin layout for the FFE ODB-II port? Whenever I plug the CanDue into the ODB-II (under the light switch), the car gives me many error messages. Here is what I've been using for a ODB-II pin diagram, but only have the +12v, GNC, CAN0LO, and CAN0HI wires attached to the CanDue.

Sefs,

I got myself a lockpick but cannot get it to work with my 2013 FFE. Called the technical support line for the lockpick, spoke with Carlos and was informed they haven't heard of anyone being able to use the lockpick on the FFE.

Do you remember or have any information on how you got the lockpick to work with your FFE?

I think I had to follow the "Cmax" instructions instead of the "Focus" instructions that came with it.

I'm planning on adding a generator for extended range since I'm in rural Kansas with no public charging access. I have everything I need including a TSM2500 lithium charger. From what I gather, max voltage is 351 correct? Here's the link. What settings do you suggest? http://www.thunderstruck-ev.com/tsm2500 ... oller.html

Well guys, it has been a fun 3 years with the mod installed. I'm trading in my FFE on Friday and picking up my Tesla Model 3, so I'll be pulling out all my mods. I really haven't had any issues with quick charging or anything over the time I've had it installed. I learned a lot, spent more than I care to add up, and had fun proving those who said this car couldn't quick charge wrong. :D
