Tesla MODEL Y 2022 - Cannot charge - Poor grid power quality possible; Poor electric grid power quality detected; External charging equipment not providing power

(PCS_a032)
Poor electric grid power quality detected
Try dierent charging station or location
Charging speed has been reduced or charging has been interrupted due to a condition that
aects 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 aecting 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 dierent wall outlets.
•
Try charging again (disconnect and reconnect to retry) when other large electric devices are
not drawing power.
•
Try charging with multiple, dierent types of charging equipment at dierent 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 on page 146 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.
(PCS_a052)
External charging equipment not providing power
Check power source or try dierent equipment
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 has requested AC power from the external charging equipment, but the onboard
charger does not detect any supply voltage coming from the equipment.
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
aecting the external charging
equipment, the power source it is connected to, or your vehicle itself.
