Re: Quick charge project

Thanks for the kind words, I've been thinking of doing this since the month 2 with the FFE :lol:

1. On the battery temperature, you're correct, it's too cold here right now to have the battery at that temp with a single charge. I would have to charge, discharge, and then on the second charge it would be at that temp; but that's kind of an all day affair. I'm definitely looking into the temperature response, because I need to incorporate that for Chademo charge rate controls.

2. Cell balancing is still permitted to take place. I terminated last night after about 85% SOC. After that, it was business as usual. Since the actual pack stops at 90% actual SOC, I'm not very concerned that it would make a single cell go crazy, but the BECM will fault and shut down if a cell would fault. I'll integrate this into the charging controls as well.

Any new update? I really want to make my car Chademo compatible or ccs combo! I will follow your thread for sure! And I've done some research the brusa charger not supposed to work on the 50hz? where i living we all are on the 60hz.

I'm still working on it. I've just been a bit busy with work. I've been working on getting the can codes from the car to control the chademo charging session with the Arduino. The brusa is 50/60 hz. That will be getting mounted under the hood soon as well.

Wow! Very exciting! I have been dreaming about putting in a 10kw charger to the car to allow me to put a 10kw generator on a hitch. This would essentially work as funky range extender. Still not sure how the car would react as it accelerates and see 10kw less than it expects.

As you start to really look toward the DC fast charge capabilities keep in mind there are now two standards. I just saw a station the other day that upgraded to the new j1772 combo port, thought that was pretty exciting.

Keep up the good work! I will be watching this thread for sure!

Bump.
+1

very interested.

if Chademo could be made to work, I'd not only pay for the parts, I'd pay someone to install it. ;)

WE HAVE CAN COMMUNICATION!!!! WOOT :D :D :D :D :D

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

Are you charging from the oem port.?

Do you need to consider wire size while dual charging.?

Eager to see how this bubbles up.

This is very exciting news. Congratulations!

Could you provide us with some details? How did you connect to the CAN bus? How do you log? Are you using a Raspberry Pi?

Questions, questions, questions :)

For Europe it would be interesting to get the Brusa NLG6 fast charger connected to the FFE:

That would be a great advantage. Charging a Focus with 22kW at home ... A dream come true ...

Tom, I did consider swapping out the OEM port for an upgraded port, but as there are very few J1772 high ampacity stations, I decided to go with a second J1772. It will go under the hood. My intention is to use it on road trips where I can pull from two J1772 stations at once.

I connected to the CAN bus through the DTC port (this is the one behind the door under the headlight switch. The other OBD2 style port below all of the knee bolsters is the same, it's just at the CAN gateway. The DTC port (it is white and behind the knee bolster door) is the one recommended by Ford to use to interface with the car.

I am using the Can Due from EVTV. It is an arduino based CAN interface device. If you want to get started, I recommend it, with the condition that you know some C programming.

It would be pretty easy to integrate the BRUSA 22kw into the vehicle. However, I don't have 50Hz or three phase at home, so it isn't very useful to me. However, I have done pretty much the same thing with the 3.3kW BRUSA unit.

I am having a replacement high voltage junction box lid machined so I can add cable glands to hook up to a new junction box. This will hold the contactors for Chademo and the battery voltage access for the BRUSA.
