NOTE: Your vehicle may not be equipped with the Battery
Health Test feature.
The high voltage Battery in Model Y is designed to perform
well over the entire lifetime of the vehicle. Like any
rechargeable battery, however, it becomes less effective over
time due to aging and usage. The energy retention of the
Battery depends on a number of factors such as age, Battery
pack size and chemistry, and how you drive and charge your
vehicle.
For an evaluation of the Battery's energy retention, touch
Controls > Service > Battery Health.
The touchscreen displays an evaluation of your vehicle's
Battery health, calculated using data from the Battery
management system and comparing it to expected energy
retention for the given battery type, age, and usage.
Optionally, you can run the Battery Health Test, which
requires Model Y to be connected to an AC charger for up to
24 hours. After you run the test, Model Y provides a
percentage that reflects the energy retention of your
vehicle's Battery compared to when it was new.
NOTE: This feature requires that Model Y be connected to
Wi-Fi or a cellular network.
NOTE: Tesla recommends using the Battery Health Test only
if there is a concern about the energy retention of the high
voltage Battery.
Running the Battery Health Test
To start the test, Model Y needs to be plugged in to an AC
charger that provides at least 5 kW of power.
In addition, make sure that all of the following requirements
are met before you begin the test.
•
There are no active alerts related to the Battery or thermal
system.
• Model Y is in Park.
• There are no pending software updates.
• There is less than 20% Battery level remaining.
When you are ready to begin the test:
1.
Plug in your vehicle to an AC charger.
2.
Touch Controls > Service > Battery Health Test. Read the
popup, then touch Start Test.
The test takes up to 24 hours to run. While the test is
running, the touchscreen displays a progress bar and the
estimated time remaining. The touchscreen will be off for
certain portions of the test, the Battery will be discharged
below 10% (and may be discharged as low as 0%), and
vehicle features (such as Sentry Mode and climate controls)
are disabled.
WARNING:
Climate control systems are disabled while
the Battery Health Test is running. Do not leave
occupants unattended in the vehicle while the test is
running.
CAUTION:
Avoid interacting with Model Y or the Tesla
mobile app during the test. You can cancel the test on
the vehicle's touchscreen or mobile app at any time. In
the event that the test fails or you cancel the test, your
vehicle will attempt to begin charging to the set charge
limit.
CAUTION:
Do not unplug Model Y while the test is
running. If you need to unplug Model Y, first cancel the
test on the touchscreen. You can cancel the test at any
time.
NOTE: While the test is running, Model Y may produce heat
and loud noises (such as the fan running at high speed). This
is normal and is not a cause for concern.
Understanding Results
Once the Battery Health Test is complete, the touchscreen
displays a percentage that represents a comparison of your
Battery's energy retention to when it was new, and the range
estimate shown on the
touchscreen may be recalibrated.
When a data connection is available, Model Y can determine
whether the energy retention is as expected based on the
vehicle's delivery date and mileage. If the energy retention of
the Battery is affecting the usability of your vehicle, schedule
a service appointment.
After the test has been completed, the Battery Health Test
will be unavailable until the Battery management system
detects that there has been a change in your vehicle's Battery
sufficient enough to be measured by a new test.
