Couldn't we design a zero resistance unit for the shunt and switch
There could be an external power supply which pushes the current
through the shunt and the rest of the outer circuit, and
electronically adjusts that voltage to compensate the losses in the
external part of the circuit, so the battery sees no outer resistance
at all, or just the contact resistance?
It might compensate for the contact resistance too, if that would be
of any practical use.
The voltage over the shunt could steer the outer voltage so it helps
the battery without changing the current which the battery can push
through the outer resistance, which now can be adjusted to be zero or
whatever we want to set it to.
When the current from the battery increases the outer circuit would
sense that and automatically adjust the outer voltage to minimize the
influence of the outer circuit.
The power supply would compensate for both the shunt and the rest of
the outer circuit.
