A "refresh" would have some significant design changes to the interior and/or exterior.
Changing out components like the battery or charging hardware wouldn't be viewed as a "refresh", just new features - something Tesla is doing continuously.
The next major change will likely be support for V3 supercharging. If this can be done with the current battery packs, then some changes may be needed in the charging port/hardware to accommodate the higher charging rate. This could require changing the battery pack, possible shifting to the batteries being used in the Model 3.
S & X sales seem to be holding well - and with Tesla emphasis on increasing manufacturing of the Model 3, completing the designs of the Model Y, Roadster 2.0 and Semi, along with the likelihood they'll establish new factories in China - seems less likely we'll see major changes in the S or X anytime soon.
With Tesla's focus on Full Self Driving - I wouldn't be surprised to see them hold off on a refresh until they are getting closer to rolling out FSD - and then redesign the interior for use when a driver will be optional.
