Why is my Tesla not charging? 9 reasons why a Tesla might not charge

It can be worrying when your Tesla suddenly stops charging properly. You might have somewhere that you urgently need to be or you may worry about potentially expensive repairs. But don’t panic! In most cases, there’s a simple reason why a Tesla failed to charge and an easy fix for the problem.

If your Tesla is not charging properly then there must be something wrong with the electricity supply, the car itself, or the charger. Below, we list 9 problems that can slow or stop the charging process.

1. A blown fuse or power cut

Before assuming that there is a problem with your Tesla or its charger, you should first make sure that you actually have an electricity supply.

Check that other electrical appliances are working and that there is not a general power cut in the area.

Next, if your Tesla is charging from a standard wall outlet, plug in another electrical item to confirm that the outlet is working correctly.

If everything seems to be fine, try removing the charging connector from your Tesla and reinserting it to restart the charging process.

2. Have you paid?

Another reason why electricity may not be flowing through the charging connector is that you have not paid or there is a problem with the payment method in your Tesla account.

If you are using a Tesla Supercharger or public charging station, you will need to pay for the electricity. In the case of Superchargers, the cost will be charged to your saved payment method.

Check the instructions near the charger and make sure you have followed all the steps correctly.

3. Connector not inserted correctly

There should be an obvious ‘click’ when you plug the charging connector into your Tesla. 

When charging commences, the light around the charging port will blink green, turning to a solid green once charging is complete.

If the connector is not inserted correctly, the blinking green light will not appear and you may see an amber light instead.

If you see the amber light or suspect that the connector may not be inserted properly, simply remove the connector and try inserting it again.

In cases where the charging system detects a fault, the charging port light will turn red.

4. Plug not inserted correctly

There are two ends to a charging cable, so even if the connector is properly plugged into your Tesla, you need to be sure that it’s properly plugged in at the other end too.

If your Tesla is not charging even though the connector is correctly inserted into the vehicle, try checking the wall outlet to confirm the plug has not come loose.

If you’re in any doubt at all, unplug the cable and connect it again, just to be sure.

5. Scheduled charge set incorrectly

This is an easy problem to miss, so it’s well worth checking if your Tesla is charging but not as much as you would expect.

It’s possible to set a scheduled start time for your Tesla to charge. For example, you could plug your Tesla in when you arrive home from work in the evening, but use the settings in your charging menu to tell the system not to commence charging until 11pm.

If your Tesla is plugged in and charging on your driveway or in your garage all night, but not charging as much as you would expect, then go to your charging menu and tap ‘Schedule Charging’. It would be that you have accidentally scheduled a start time and your Tesla is charging for less time than you think.

6. Supercharger network bans

Tesla has the ability to ban certain vehicles from using its network of superchargers. 

The company has been known to do this with salvaged Teslas, claiming that the ban was implemented for safety reasons.

If you know your Tesla is a salvaged vehicle, and it’s only when using superchargers that your battery fails to charge, then this could be the cause of the problem.

If you suspect your vehicle may have been wrongly excluded from the supercharger network then the best course of action is to contact Tesla customer service.

7. Damage to public chargers

Public charging stations are used a lot and, as with many public amenities, they’re not always kept in top working order.

If your Tesla is not charging at a public charging station, it could be that the charger is to blame.

To confirm whether this is the problem, the simplest solution is to move to another charger and try again.

8. Charging port damage

This is rare, but it is possible for the charging port of your Tesla to become damaged, or even corroded, over time.

If you see anything that looks unusual around the charging port, you should contact a Tesla Service Center immediately.

9. Battery damage

Physical damage to your Tesla battery is rare, as the battery is well protected inside the vehicle. However, if your Tesla is not charging properly then the battery is an obvious potential cause of the problem.

It’s also normal for battery performance to steadily decline over time. Older batteries that have gone through many charging cycles will start to hold less charge and you may notice that the same amount of charging delivers less range than it used to.

If you suspect there is a problem with your battery then you will need to contact a Tesla Service Center.

You can extend the lifespan of your battery by only charging to approximately 90% of capacity. Following advice from Tesla, you should only charge your car battery to 100% when you need to make a long journey.
