Abstract:
Electrification of always more powerful systems is usually correlated to higher needs in reliability, service continuity and energy exchanges between sources. In the field of energy storage systems, these needs are often addressed by parallelization of batteries, which are automatically disconnected in case of fault. The service continuity is thus simply ensured. If the disconnection of two batteries in parallel is an instantaneous process well controlled, the connection is a longer process more complicated, which requires adapted power electronics solutions. Based on an existing case of application and thanks to simulations, we propose in this paper to compare different solutions to exchange energy between two lithium ion battery systems.
