Parts of the research leading to these results have received funding from the Energie Campus Nürnberg (“EnCN”) financed by the State of Bavaria (Germany) as part of the program “Bavaria on the Move”, and the SEEDs project funded by the Bavarian State Ministry of Economic Affairs, Infrastructure, Transport and Technology. Further funding was received from the European Union Seventh Framework Program (FP7/2007-2013) under grant agreement no 285739 (“ESTRELIA”); and from the ECSEL Joint Undertaking under grant agreement no 662192 (3Ccar) and grant agreement no 737469 (AutoDrive). This Joint Undertaking receives support from the European Union's Horizon 2020 research and innovation program and the ECSEL member states (i.e., BMBF for Germany). Some further funding was received from the Federal Ministry of Education and Research of Germany under grant agreement no 03XP0027F (“MiBZ”).

Abstract

This paper presents a new power electronic device, named power antifuse, providing an irreversible bypassing function for the current after having been ignited by an external electrical signal. The antifuse is a scalable power electronic device of 1 cm2 of active area. A pristine antifuse device provides an electric resistance of more than 100 mega-ohms between the terminals. 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. 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°C. 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 characteristics of the proposed antifuse device make it also an ideal power electronic device for bypassing faulty series connected sub-systems used in high-availability applications or fail-operational redundant systems.
