It can be very frustrating if you find your vehicle is not charging as expected, and the cause may not be obvious immediately.
This troubleshooting guide should help you determine the cause of the issue.
First, please make sure the cable is plugged in firmly and securely, and not damaged or dirty. Check the plug for any debris or obstructions. If you have an untethered charger, check both ends of the cable.
This troubleshooting guide is split into three sections and we would advise reading the whole guide as there is some overlap between these sections.
Several factors on the vehicle side can interrupt the charging process.
Firstly, ensure you have followed the process specified by your vehicle manufacturer for charging the vehicle, for many vehicles this normally involves locking the doors, for example. That may be different for your vehicle, if you aren't sure, consult your vehicle handbook or contact the manufacturer.
Ensure the cable is fully slotted in place in the vehicle, and the charger if you have an untethered model. Check for any debris or corrosion in the plug.
Some vehicles allow you to set a limit on the battery, if your charging stops at 80% regularly, check your vehicle settings for any battery limits.
If your vehicle allows you to schedule charge sessions, if you are outside of the scheduled charge window then your vehicle will not charge.
Some smart tariffs such as Intelligent Octopus Go, take over the charging process and control your vehicle directly to dynamically schedule charge sessions for specific times. Outside of these times, you may need to "nudge" your vehicle to commence charging, this would most likely be controlled by your energy providers app.
Make sure your vehicles software is up to date and check for any errors. Vehicles can encounter various errors while charging, these might be signified by colour coded error states, or pop up messages on the infotainment system.
Is there power?
Check your charger for any signs of life. If your charger is powered, the status LED should be illuminated (unless you have toggled off the "always on" setting). Check what colour the LED is, refer to the *manual* to find out what each colour corresponds to.
If the status LED is set to always on in the settings and it is not illuminated, this usually means your charger is not powered. Check the fuse to see if the breaker has tripped and reset it if so. Nuisance tripping can occur if the installed breaker is not rated 40 A. Please contact your installer if the tripping continues.
If the breaker hasn't tripped, move it to the OFF position and leave it for 2 minutes. Move the switch back to the ON position, and check your charger, if there is still no sign of life there may be an issue with the installation, so please contact your installer to check the installation to ensure the charger is powered.
If the status LED is white, this means your charger is in standby and ready to charge. If your cable is plugged in, it might not be fully inserted.
If the status LED is blue, the charger and vehicle are connected and the charger is waiting for a signal from the vehicle to commence charging.
A yellow status LED indicates the charger is scheduled to charge, it will not charge outside of the scheduled window, unless you press the override button on the app or the charger.
A red status LED means your charger is locked, unlock it via the app to charge.
If you see red flashing LED, there is a fault somewhere, please check the Simpson app for further information.
The Simpson app will give you information about any errors the charger encounters. There are a few errors that limit or stop charging.
If your charger is not charging as expected, check the app for any error information. Some of these charge preventing errors are : insufficient supply voltage, high loading, PEN faults, overheating.
The padlock button on the app locks your charger, indicated by a solid red LED. While locked, your charger will not charge.
