No, the SE will only heat/cool the cabin air. It does not precondition the battery.
If you set the departure time (either for 'comfort climate' or 'plan charging'), the SE will begin heating/cooling the cabin automatically so it will be "comfortable" in time your programmed departure time. If you activate it manually via the app, I'd say ~15 minutes will usually do the trick.
