Method for operating a lithium accumulator on an on-board network designed for lead accumulators in a submarine

摘要

The present invention relates to a method for operating a DC voltage converter 30, 32 on board a submarine, the DC voltage converter 30, 32 being arranged between at least one first lithium battery 20 and a first on-board network 60 of the submarine, the method having the following steps: a) measuring the voltage applied to the vehicle electrical system 60, b) measuring the current flowing into the vehicle electrical system 60, c) detecting a potential short circuit in the vehicle electrical system 60 due to low voltage and high current, d) temporarily increasing the maximum current for the applied voltage.
