4 Reasons Your Tesla Is Not Charging With An Extension Cord

4 Reasons Your Tesla Is Not Charging With An Extension Cord

Having a Tesla is a great mix between going green and saving gas money. You park your car at home, plug it in that charger, and wake up to a full battery. Simple as that.

However, what if you discover that your Tesla isn’t charging with extension cord? What could the problem be there?

This article will show you the four main reasons for that.

1. Wrong Type of The Extension Cord

Tesla extension cords are made from heavy-duty materials to withstand the strong electric current needed to charge the battery.

If you’re charging your Tesla with an extension cord that lacks the specifications for doing this job, it may overheat, malfunction, or get permanently damaged. 

So, buying kits and adapters from Tesla’s collection is always better. They have all the types of equipment that go with any standard outlet. 

2. No Steady Power Supply

If your Tesla is charging and it senses sudden changes in the input power, it will immediately reduce the charging current by 25% to prevent damage to the battery.

For instance, a 40-ampere current is decreased to a 30-ampere current. This automated current reduction promotes stability and safety when an external hazard is present. 

Tesla advises charging at the lower current until the underlying issue is fixed and the charging station can supply steady power.

3. Charging Port Issue

If the green light doesn’t flash when you plug an extension cord, you have a charging port issue. 

To fix this, Press the RESET button after unplugging the mobile connector from your Tesla, then reconnect the Mobile Connector to it.

If the issue persists, unhook the Mobile Connector from both the power source and the outlet, then replug it into the outlet first, followed by the power source.

If the issue persists, you can try to repair the cord at the Tesla service center. It’ll be free of charge if it’s still under warranty. 

4. Software Glitches With Charging

If you updated your Tesla software and now can’t charge your car, the reason might be a recent software update. 

Your best practice to solve this is to reboot the car so your Tesla gets to refresh its software. You have the choice of doing a soft or a hard reboot. We recommend beginning with the soft one since it’s faster and easier. 

To do a soft reboot, press and hold the scroll wheel until all the screens go off. Then after 10–20 seconds, the touchscreen and control gadgets will start again, and the reboot ends.

If this doesn’t work, go for the hard reboot

Final Thoughts 

Tesla not charging with extension cord? You are maybe using the wrong type of extension cord or simply a damaged one.

Additionally, Tesla cars can sense unsteady power, and that may lower the charging speed considerably and occasionally stop it.

Software glitches may also be the culprit behind this, so don’t hesitate to contact Tesla’s customer support for help.
