This paper shows how the integration of antifuse devices in battery cells can be used to bypass and turn-off lithium-ion battery cells thus improving the safety and availability of battery systems used in transport applications like aircraft, railways, ship and road vehicles.

The activation time corresponding to the delay between the reception of the electrical trigger signal and the full conduction of the antifuse is less than 10 ms even at environment temperatures below -40☌. After having been activated, the same antifuse device becomes a bidirectional bypass element offering less than 20 micro-ohms of resistance to the electric current.

A pristine antifuse device provides an electric resistance of more than 100 mega-ohms between the terminals.

The antifuse is a scalable power electronic device of 1 cm² of active area.

The process is different for other ECUs I'd imagine.Ģ.13V Ktag Master V6.070 Plus V2.15 Kess V2 Unlimited Token V4.036 with Free ECM TITANIUM V1.61 Software:Ĭar Key Programmer Auto Diagnostic Tool Categories I now write my custom tunes with Kess to the ECU, and KSuite corrects the checksums for the partial writes. I did this with a FGTECH V54 but the process is the same for Kess.

So the secret is to do the write directly after the read. Whenever I tried to write the tune file, the ECU would be bricked and come back with a checksum error after the write. I did a full read a month ago, and only did a full write a week ago. The reason for the full read and full write is that it takes off the tuning protection on the ECU. After you've done that, the ECU is open for you to load your tunes based on partial reads and writes. Then why Ktag / Kess checksums error and how to prevent it happens?Īt first, I also have this error, but finally I find out the reason, and I hope I share here to help others.Īccording to this ECU, you must do a full read and then straight after that you must do a full write. And this error happens on both Chinese clone Ktag/Kess and EU clone ones. the units will not calculate checksums when loading files. Some users feedback they have a same problem with Ktag and/or Kess v2 Masterchecksums error eg.
