Porsche Taycan Won’t Charge – Top 3 Reasons!

The Porsche Taycan is one of the most potent EVs on the market. But no matter how powerful it is, it’s useless if you can’t charge it. Sit tight, and we’ll have you charging shortly.

Top reasons your Porsche Taycan is not charging include:

  1. Charge point fault
  2. Scheduled charging set
  3. Charge limit set

In this article, we’ll look at the reasons why it’s not charging and how to fix the problem.


Charge Point Fault

The most common reason your Porsche Taycan won’t charge is a problem with the charge point, either at the wall or at the car.

Wall Charge Fault

Every Taycan comes with a standard plug-in charger. However, most dealerships upsell and include the 9.6kW Wi-Fi charger. It’s a pretty neat bit of kit. It has your cable, which has your mobile connector, but at the wall end, you can either put a 120V or a 240V adaptor on it.

However, you must install a Level 2 – 240V connection at your house. This is the equivalent of a stove connection or an electric shower. A qualified electrician must install it. The 240V uses a Nema 14-50 plug that connects to a Nema 14-50 socket. This allows up to 40A of charge.

If your Taycan doesn’t charge using the 14-50 adaptor, I suggest you swap it for Level 1 – 120V to confirm that the 14-50 might be the problem. If so, you must contact an electrician to test your connection.

If Level 1 doesn’t work either, it could be that the circuit has tripped. There has more than likely been an overload of your circuit. The 240V is required for heavier electric items in your home, and if there is a fault, your circuit board will automatically shut them down to prevent a fire.

Check your circuit board and ensure all zones are on. If everything seems in order, the cable could have a fault. The cable that Porsche supplies with the Taycan is only 8ft long.

It’s unusual in that the charging unit is below the plug and requires the housing for the wall bracket to be installed much lower than normal (if you are utilizing a socket that is already there).

With that said, the cable could have been jarred somehow and is no longer making a complete seal. If a full seal is not in place, then charging can’t occur. Again this is a job for a qualified electrician to have a look at.

Fault in the Car

Every Taycan comes with two charge ports on either side of the car. They are located just between the wheel arches and the driver and passenger doors. The only difference between them is that one has an additional port to allow fast charging. They both have the level 1/2 port. When one is in use, the other port becomes deactivated.

When charging begins or when you plug in the cable, there is a selection of lights that will indicate what is going on:

Light ColorMeaning
White – BlinkingEstablishing connection
Green – BlinkingCharging occurring
Green – OnCharging complete
Blue – BlinkingCharging paused
RedCharging error
Porsche Charging Lights

Let’s look at the possible charging problems through the meaning of the lights. White light blinking. This light means the initial plug-in has happened.

The onboard computers in your Taycan check that both the charge port in your car and the plug at the wall are safe and secure. During this time, the light blinks white and will either turn green blinking or blue blinking or red.

Green blinking represents charging is normally occurring. If you cannot charge, your light will either be blue or red.

Blue light means that a scheduled charge setup is in place. You can override this by hitting the Direct Charging button on the lower internal screen. Scheduled charging is set to avail of cheaper electricity rates and convenient overnight charging. We’ll look at this further a little later in the article.

The red light on your charge port denotes that there is an error in your cable / mobile charger or the supply to your car. Red lights mean no charging is possible. You can adjust or test a few things to try and get it going.

Red light can occur if the power plug in the car or the wall is overheating. This can be because the incorrect adaptor is being used on your cable. Charging will restart or start when the plug cools down to normal. If the control unit has a yellow light, it is overheating. This will need a qualified electrician to look over.

If your circuit has insufficient power, the light could also be red. This may be grid limiting from the city or insufficient voltage is going to your circuit.

The system has encountered a fault if the light is red at the car’s end. Disconnect the charger from the car and then from the wall. Leave disconnected for at least 60 seconds and plug everything back in again. Hopefully, the problem has fixed itself. If not, you must contact your Porsche dealership and schedule a service check.

Scheduled Charging Set

Your Taycan has a sophisticated charging setup. It can be programmed to charge when you want and where you want. Even though you may have just purchased your Taycan, a scheduled charge setup might already be in place.

This is because the dealership where it was previously living had to keep it alive, so to speak, in case someone wanted to do a test drive.

When you plug your car in, and the lights are blue, you can override this with the Direct Charging button, but you also need to go into the system to see what exactly is set up in ways of charging and change it to suit your needs.

  • On the Home Screen, select Charging
  • Select Overview

Here you can see any information relating to your current charging setup.

You need to add a profile to set your Taycan to charge when you have cheaper electricity or to have it charged when you’re ready to leave the house.

  • Select +Add Profile
    • Add Name – Home / Work
    • Use current location

When you reach within a certain radius of the set location, your car will automatically know because of the GPS. Your onboard computer will check the status of your battery, and if the % is below 25%, it will automatically charge this amount regardless of the scheduled charge setup.

This is possibly why you haven’t realized a scheduled charge was in place, as each time you have pulled in, the battery is below 25%. To set up the specific charging times, you need to do the following:

  • Set preferred charging times (usually through the night)
  • Select Depart time
  • Select Date
  • Select Repeat for any days that are the same
  • Click Back
  • Click Home
    • Your charge light will now be blue
    • Your information screen will display the current battery level, the range, and the time it will be charged.

Porsche recommends that you keep your charge at 85% or below. This is to save the Lithium Ion batteries. The higher the charge, the hotter the cells get, which leads to the battery’s degradation.

To enable the scheduled timer, it needs to be selected on the home screen. Although it is saved as a preset, unless it is actually checked, it won’t activate. When you activate it, the blue screen information will update.

Charge Limit Set

The charge limit is important as we want to get the best from our battery. As I said, 85% is the magic number. Porsche (and most EV brands) believe that if you charge your car to 85%, you will have longevity in your battery. Of course, this isn’t always practical or possible, and sometimes charging calls for it to be all the way to 100%.

Be it a road trip or you’re going somewhere you know there isn’t a huge amount of chargers. And of course, this is perfectly fine, but you should keep within 85% on a day-to-day basis.

You can set this target amount on your home screen.

  • Select Overview
  • Select Target
  • Set this target to 85%.

There are definitely going to be times when you need the full 100%; if you do have to override the 85%, don’t forget to revert it. Your batteries will thank you for it.
