Tesla MODEL Y 2012 Owner's Manual page 167

NOTE: If Model Y is charging and detects unexpected
fluctuations in input power, the charging current is
automatically reduced by 25%. For example, a
40 amp current is reduced to 30 amps. This
automatic current reduction increases robustness and
safety in situations when an external problem exists
(for example, a home wiring system, receptacle,
adapter or cord is unable to meet its rated current
capacity). As a precaution, when Model Y
automatically reduces current, it saves the reduced
current at the charging location. Although you can
manually increase it, Tesla recommends charging at
the lower current until the underlying problem is
resolved and the charging location can provide
consistent power.
• Schedule: Depending on the setting you select by
touching Switch to Scheduled Departure/Scheduled
Charging, this displays either a departure time for
when the vehicle should be preconditioned and/or
charged by or a time to start charging (see
Scheduled Charging and Scheduled Departure on
page 165).
• Supercharging: Displays supercharger usage fees, the
location, the time that charging started, and a cost
estimate for the session (see
Fees and Idle Fees on page
NOTE: To reduce congestion at high-usage
supercharger sites, you may be limited to a maximum
charge of 80% when not using Trip Planner (if
available in your market region). See
page 133).
Scheduled Charging and Scheduled
Departure
Toggle between Scheduled Departure and Scheduled
Charging by touching Controls > Charging > Switch to
Scheduled Charging/Scheduled Departure when Model
Y is in Park.
NOTE: Scheduled Charging/Scheduled Departure
settings are also available on the Climate Controls
screen and in the Tesla mobile app.
Think of Scheduled Charging as "When do I want
charging to start?" compared to Scheduled Departure
Off-Peak Charging which is "When do I want charging to
be complete?"
Scheduled Charging can be used together with
Scheduled Departure Preconditioning but not with
Scheduled Departure Off-Peak Charging.
Scheduled Charging/Scheduled Departure settings are
automatically saved for each location.
NOTE: If you plug in Model Y with both Off-Peak
Charging and Scheduled Charging deselected, your
vehicle charges immediately.

Using Scheduled Charging
Use Scheduled Charging to specify a daily time in which
you want Model Y to start charging.
With Scheduled Charging selected, enable the feature
then set a daily time to start charging.
NOTE: Scheduled Charging starts charging immediately
if Model Y is plugged in up to 6 hours after the
scheduled start time. However, if Model Y is plugged in
after six hours of the scheduled charging time, charging
may not start until the scheduled time on the next day.
Using Scheduled Departure
Use Scheduled Departure to set a daily time when you
want Model Y to be ready to drive. Your vehicle
automatically calculates when it needs to start
preconditioning and/or charging. This ensures that
charging is complete and/or the cabin climate and
Battery are preconditioned by your departure time.
When Scheduled Departure is displayed, touch
Schedule to set a daily time when you want Model Y to
be ready to drive. Specify a time, then touch Settings to
enable one or both of the following departure features.
When plugging in with Off-Peak Charging enabled, the
vehicle briefly draws power (you may hear clicking) to
calculate the necessary charging start time.
After you've specified your desired settings, touch Set.
The touchscreen displays your scheduled departure
time.
• Preconditioning warms the Battery for improved
performance and ensures a comfortable cabin
climate at your set departure time.
NOTE: When Model Y is not plugged in,
preconditioning operates but only when the Battery's
charge level is above 20%.
• Off-Peak Charging delays charging and automatically
starts charging in order to finish before your
scheduled departure time while also ensuring to
charge the Battery during off-peak hours to reduce
energy costs. Touch Change Off-Peak Hours to
customize the time when off-peak utility rates end.
NOTE: Choosing Off-Peak Charging can reduce
energy costs even in market regions where off-peak
utility rates are not applicable. For example, if
charging starts as soon as you plug in, charging may
complete much sooner. This causes the Battery to
cool down to ambient temperatures and requires
energy to warm it back up by your departure time.
Therefore, even if off-peak utility rates are not
applicable to you, it is recommended that you set
Off-Peak Hours to the same time as your departure
time in order to reduce energy consumption.
