About the High Voltage Battery
Model X has one of the most sophisticated
battery systems in the world. The most
important way to preserve the high voltage
Battery is to
LEAVE YOUR VEHICLE
PLUGGED IN
when you are not using it. This
is particularly important if you are not
planning to drive Model X for several weeks.
NOTE:
When left idle and unplugged, your
vehicle periodically uses energy from the
Battery for system tests and recharging the
low voltage battery when necessary.
There is no advantage to waiting until the
Battery’s level is low before charging. In fact,
the Battery performs best when charged
regularly.
NOTE:
If you allow the Battery to discharge to
0%, other components may become
damaged or require replacement (for
example, the low voltage battery). In these
cases, you are responsible for repair and/or
transporting expenses. Discharge-related
expenses are not covered by the warranty or
under the Roadside Assistance policy.
The peak charging rate of the Battery may
decrease slightly after a large number of DC
Fast Charging sessions, such as those at
Superchargers. To ensure maximum driving
range and Battery safety, the Battery charge
rate is decreased when the Battery is too
cold, when the Battery’s charge is nearly full,
and when the Battery conditions change with
usage and age. These changes in the
condition of the Battery are driven by battery
physics and may increase the total
Supercharging duration by a few minutes over
time. You can minimize the amount of charge
time by using Trip Planner to warm the
Battery while driving to a Supercharger. See
for more
information.
Battery Care
Never allow the Battery to fully discharge.
Even when Model X is not being driven, its
Battery discharges very slowly to power the
onboard electronics. The Battery can
discharge at a rate of approximately 1% per
day, though the discharge rate may vary
depending on environmental factors (such as
cold weather), vehicle configuration, and your
selected settings on the touchscreen.
Situations can arise in which you must leave
Model X unplugged for an extended period of
time (for example, at an airport when
traveling). In these situations, keep the 1% in
mind to ensure that you leave the Battery
with a sufficient charge level. For example,
over a two week period (14 days), the Battery
may discharge by approximately 14%.
Discharging the Battery to 0% may result in
damage to vehicle components. To protect
against a complete discharge, Model X enters
a low-power consumption mode when the
displayed charge level drops to approximately
0%. In this mode, the Battery stops
supporting the onboard electronics and
auxiliary low voltage battery. Once this low-
power consumption mode is active,
immediately plug in Model X to prevent a
jump-start and low voltage battery
replacement.
NOTE:
If Model X is unresponsive and does
not unlock, open, or charge, the low voltage
battery may be discharged. In this situation,
try jump starting the low voltage battery (see
Instructions for Transporters on page 247
for
instructions on how to jump start the
battery). If the vehicle is still unresponsive,
contact Tesla.
Temperature Limits
For better long-term performance, avoid
exposing Model X to ambient temperatures
above 140° F (60° C) or below -22° F (-30° C)
for more than 24 hours at a time.
Energy Saving Feature
Model X has an energy-saving feature that
reduces the amount of energy being
consumed by the displays when Model X is
not in use. On newer vehicles, this feature is
automated to provide an optimal level of
energy saving. However, on older vehicles,
you can control the amount of energy being
consumed by the displays by touching
