Tesla Model S: Poor electric grid power quality detected
Try different charging station or location
Charging speed has been reduced or charging has been interrupted due to a
condition that affects your vehicle's
ability to charge with AC power. DC fast charging / Supercharging should still
function as expected.
The onboard charger in your vehicle has detected power supply disturbances in
the electrical power grid. These
disturbances interfere with your vehicle's charging process.
Typical causes of these power supply disturbances include:
- Issues with the building wiring and/or the wall outlet.
- Issues with the external charging equipment.
- Other large electric devices, such as washing machines or air
conditioning units, that temporarily draw a lot of
power or otherwise disturb the electrical power grid.
- External conditions affecting the electrical power grid.
As 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:
- Try charging with different wall outlets.
- Try charging again (disconnect and reconnect to retry) when other large
electric devices are not drawing power.
- Try charging with multiple, different types of charging equipment at
different locations.
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 131 for more
details. Additional third-party charging stations may also be available in your
area to help you to pinpoint the issue.
For more information on troubleshooting Mobile Connector or Wall Connector
status lights, refer to the product's
Owner's Manual at Charging & Adapter Product Guides. If using other external
charging equipment, refer to the
manufacturer's provided documentation for troubleshooting tips.
