Abstract: A current limiter arrangement limiting an electric current between a first and a second terminal includes a first current limiting device and a second current limiting device arranged between the first and the second terminal. The first and the second current limiting device each include a substrate having a substrate surface area and a substrate thickness, and include a superconducting section arranged on the substrate and thermally coupled to the substrate thereby covering a coupling surface area on the substrate. Each of the superconducting sections has a critical current value and the substrate surface areas, the substrate thicknesses and or the coupling surface areas are implemented as a function of the critical current values.

Abstract: Methods and apparatuses for accurately estimating an internal temperature of a secondary battery with a charging rate SOC and a charge/discharge state taken into account are provided. A method may include a method of estimating an internal temperature (T) of a secondary battery for a vehicle, which includes a change determination process to be repeatedly performed and an internal temperature estimation process to be repeatedly performed.
