Changing Charge Settings

The charge settings screen displays on the
touchscreen whenever the charge port door is
open.
To display charge settings at any time, touch
the Battery icon on the top of the
touchscreen, or touch Controls > Charging
(located in the upper right portion of the
Controls screen).
The following illustration is provided for
demonstration purposes only and may vary
slightly depending on the firmware version
and market region of your Model S.
1. Charge status messages (such as
Charging Scheduled, Charging In
Progress) display here.
2. Adjust the charge limit based on your
anticipated driving needs. Touch Set
Charge Limit, then drag the slider bar to
the desired charge level. You can charge
to any level from 50% to 100%. For daily
driving, charge between 50% and 90% to
improve battery longevity. Charge above
90% for trips requiring maximum range.
The setting you choose applies to both
immediate and scheduled charging
sessions.
3. Location-specific schedule
With Model S in Park, set a specific time
when you want Model S to begin charging
at the current location. If, at the scheduled
time, Model S is not plugged in at the
location, it will start charging as soon as
you plug it in as long as you are plugging
it in within six hours of the scheduled
time. If you plug in after six hours, Model S
does not start charging until the
92
scheduled time on the next day. To
override this setting, touch Start Charging
or Stop Charging (see item 4). When you
set a scheduled charging time, Model S
displays the set time on the instrument
panel and the touchscreen.
4. Touch to open the charge port door or to
start (or stop) charging.
5. The current automatically sets to the
maximum current available from the
attached charge cable, unless it was
previously reduced to a lower level.
For 3-phase charging, the available
current represents the current per phase
(up to 32 amps). During charging, the
right status flag displays the 3-phase
symbol in front of the displayed current.
If needed, touch the up/down arrows to
change the current (for example, you may
want to reduce the current if you are
concerned about overloading a domestic
wiring circuit shared by other equipment).
It is not possible to set the charging
current to a level that exceeds the
maximum available from the attached
charge cable.
When you change the current, Model S
remembers the location. So if you
subsequently charge at the same location,
you do not need to change it again.
Note: If Model S automatically reduced a
charging location's current because of
fluctuations in input power (see the note
in Charging Status
recommends charging at the lower
current until the underlying problem is
resolved and the charging location can
provide consistent power.
