Unable to charge with Mobile
Connector
Voltage too low / Try a
different wall outlet
The vehicle cannot charge, or charging is
interrupted, because either the Mobile
Connector:
• Does not detect enough supply voltage
from the wall outlet.
OR
• Detects an unexpected drop in supply
voltage from the wall outlet.
Try charging the vehicle with a different wall
outlet.
If the vehicle starts to charge, the issue was
likely with the original wall outlet. It is
recommended that you contact an electrician
to inspect the building wiring connection to
that outlet.
If the vehicle still does not charge when you
try a different wall outlet, try charging at a
different location.
As explained above, this alert is usually
specific to external charging equipment and
power sources, and it does not typically
indicate an issue with your vehicle that can be
resolved by scheduling service. It is
recommended that you instead make sure:
• You have tried charging with different
wall outlets.
• You have tried charging with different
charging equipment.
• The vehicle does not charge or
unexpectedly stops charging during every
charging attempt.

Charging stopped
High temperature detected by
Mobile Connector
High temperature detected by Mobile
Connector alerts indicate the outlet used to
charge is becoming too warm, so charging
has stopped to protect the outlet.
This is not typically an issue with your vehicle
or your Mobile Connector, but rather an issue
with the outlet. A warm outlet may be caused
by a plug that is not fully inserted, a loose
building wiring connection to the outlet, or an
outlet that is beginning to wear out.
To regain normal charge operation, make sure
your adapter is fully plugged into the outlet. If
charging speed does not return to normal,
contact an electrician to inspect the outlet
and building wiring connections to the outlet
and complete any repairs needed.
If the outlet is worn, it should be replaced
with a high-quality outlet. Consider upgrading
to a Tesla Wall Connector for greater
convenience and highest charging speed.
