How to fix the Porsche LFP battery？

[@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.

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

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

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.

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.
