Re: HV battery replacement

So here is my battery label - clearly states 33.5kWh https://i.ibb.co/xmTqdr1/IMG-20190711-193249437.jpg But I don't see any HM5 BECM firmware availabe (there is H1F) and car works like this battery was 23kWh. Any idea where to look for solution? Ford support is out of question as this car was impor...

Re: Quick charge project

I've been trying to sniff what Forscan does and it's sending some requests as it shows cell min voltage.

One more question - during the AC charging is the charging power given somewhere in CAN frame or I would have to calculate like amps times pack voltage?

Re: Quick charge project

Sefs,

Can you ask for voltage of any cell or you just can get min-max?

Re: Quick charge project

Here is fully charged car: https://i.ibb.co/tHbm8Tm/full.png So car screen shows 100% charge - but: B3 and B4 says hex 0384 = dec 900 so SOC is 90% B6 on the other hand says hex C8 = dec 200 so div by 2 gives 100%. This must be the info car displays as no other values change that much during chargin...

Re: Quick charge project

Nice work! Glad to see someone working at figuring out how things work on the FFE. I'm using this great tool called SavvyCan - will find out soon what bytes change during charging session as now I know what ID to look at. So it looks like only bytes 3 and 4 are changing during charging session. Tho...

Re: Add original CCS Combo in car 2012-2015

I suspect you need different firmware in the car to see this. I installed the GFM2 block in accordance with the original diagrams and added the port of the charging line. Errors in the diagnosis, he does not write. But charging does not start ( Are there people on the forum who do fast charging in g...

Re: Quick charge project

sefs , Can you sell your work, or show the scheme / sketch / firmware and controller? How to add two 6.6kW inverters to the car to be charged from a 3-phase outlet? I think it was mentioned before that you can't charge faster than 11kW via AC as car will get into faulty state. All you can add is 3....

Re: Quick charge project

OK so I have found some time to play with CAN as it gets warmer. My method is kinda brute force. I'm replaying messages previously recorded at different car state (like SOC, weather). I don't see people are willing to share the knowledge so I will do - as there is so little known about FFE CAN and e...

Re: HV battery replacement

That would be great - the only problem is that I have imported this car from Canada and I live in Europe :) - I'm almost 100% sure no Ford dealership here is able to do that :(
