Keep in mind that a superconducting energy storage device is kind of the opposite of a battery. An idle battery at full charge has some voltage and zero current, and it’s perfectly happy to stay like that.
An idle superconducting energy storage at full “charge” is not carrying a charge at all — it’s carrying a current. If you cut the wire (or blow a fuse), V = L dI/dt will generate an arbitrarily high voltage to keep that current flowing.
I imagine one would need some spark gaps and/or capacitors to limit the voltage.

This is how Kamerlingh Onnes injected current into his superconducting media during the original experiments and that is a two-way street. https://www.lorentz.leidenuniv.nl/history/cold/DelftKes_HKO_PT.pdf https://www.lorentz.leidenuniv.nl/history/cold/DelftKes_HKO_...
