How to fix the Porsche LFP battery？

[@KTuser12]

Thanks for video. Can you do it remotly?

[@mysupercarexpert]

Hi, we can provide file, however you need to get to the PCB and read the file then we can fix it. Alternatively, on Cayenne there is the AGM conversion kit: mysupercarexpert.com/products/porsche-cayenne-9y-12v-battery-swap-kit-lithium-to-agm?_pos=1&_psq=agm&_ss=e&_v=1.0

I took bms off can you programme it remotly?

[@CATA20034]

I have a few of them around, you need only the copied files? I don't have the sicker from the battery, or let's say I have but they are mixed, don't know what cover is correlated to the BMS, as I have them dissembled.

[@mysupercarexpert]

File is enough, there will be part number written inside. Just send both flash and eeprom and we can take care of it!

@@mysupercarexpert Do you know if it can be read by SEGGER J Link ?

[@mysupercarexpert]

@@CATA20034 Did not try, however if CPUs are supported I don't see why not. They don't have protections. Depending on battery model it's either a 9S12 or SPC5644B

My battery completly dead and I tried to charge it no results. Do you think software update will resolve the issue?

I don't want to ever own a car where the battery has a cpu inside it big enough to run Windows 11 🤣

Hi what do I need to connect BMS to my computrr?

[@mysupercarexpert]

A programmer like VVDI Prog would be perfect. Any programmer able to support MPC5644B or 9S12 processors will be fine for current 12V Porsche batteries.

Hello, I have a problem with the same battery. In the dashboard it says battery low, but when i charge it is good. How can i fix it?

[@mysupercarexpert]

Hi, when lithium batteries get older, their efficiency is lower, meaning they get from full charge to no charge very quickly. In this case the normal solution is to replace the battery or attempt a repair with a proper 12V lithium charger in repair mode.
