Charging has been interrupted because the onboard charger in your vehicle has detected an unusually large voltage
drop.
Likely causes of this issue include:
• Problems with the building wiring and/or the wall outlet.
•
An extension cord or other wiring that cannot support the requested charge current.
This issue can also result from turning on electric devices that draw a lot of power from the same branch circuit
while the vehicle is charging.
What to do:
If this issue has occurred multiple times at your normal charging location, contact an electrician to inspect the
electrical installation. They should check the following:
•
Any installed charging equipment and its connection to the building wiring.
• The building wiring, including any wall outlet used with a Mobile Connector.
• The electrical connection to the power utility line where it enters the building.
Discuss with the electrician whether the charge current on the vehicle should be lowered, or if the installation should
be upgraded to support a higher charge current.
This alert is usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
be located through the map on your vehicle's touchscreen display. See Maps and Navigation on page 164 for more
details.

External charging equipment error detected
Try dierent charging equipment
What this alert means:
AC charging cannot begin due to a condition that prevents your vehicle from charging with AC power. DC fast
charging / Supercharging should still function as expected.
Your vehicle's onboard charger is detecting input voltage at the charge port when no power has been requested
from the external charging equipment, which indicates the external charging equipment is not functioning as
expected.
This can sometimes be caused by a hardware issue specific to the external charging equipment, which prevents the
charging equipment from switching power to the vehicle on or
o when requested. It could also occur due to
another condition aecting the external charging equipment, or a condition aecting your vehicle itself.
What to do:
This alert is usually specific to external charging equipment and power sources and does not typically indicate an
issue with your vehicle that can be resolved by scheduling service.
Try charging with multiple, dierent types of charging equipment.
You can also try charging your vehicle using a Tesla Supercharger or Destination Charging location, all of which can
