When charging your Jeep 4xe is the only way to get to work. Your Jeep 4xe is not charging, you are in one of the most frustrating situations where your Jeep is just a massive paperweight when the battery is below 1% or dead, and the panel state of charge indicator indicates problems with charging or nothing at all.
In our last post about the best Jeep 4xe chargers, we spent time testing and reviewing the top chargers available in the market today, including the #1 Grizzl-E Level 2 EV Charger, #2 JuiceBox 40 Smart charger, #3 ChargePoint Home Flex charger, and the #4 MUSTART Level 2 Portable EV Charger all of which we had purchased for the purpose on testing which one amongst the four chargers is the best if you are still wondering which is the best one read more here.
If you have purchased the above Jeep smart chargers we recommend or you are using the OEM charger that came with your Jeep and the charger is currently not charging don’t worry; we have analyzed some common problems that will lead to your Jeep 4xe not charging and some of the solutions we have to help you fix your Jeep 4xe not charging.
Jeep 4xe owners may encounter a range of challenges when it comes to charging their Jeep 4xe in public charging stations, we have highlighted in the chart below the most likely reasons why your Jeep 4xe is not charging.
As shown in the chart above, potential public EV charging issues include problems with station connectivity (55%), which can disrupt the smooth flow of charging sessions. Internal faults or errors within charging stations (38%) may also arise, posing obstacles to efficient charging. Additionally, problems related to charging connectors or cables (4%) could occur, affecting the effectiveness of the charging process. Moreover, credit card reader and display issues (1%) may impede payment transactions and overall user experience at charging stations.
If you are using a Home EV charger, and your Jeep 4xe is not charging, there are three main culprits; the first common one is the source of your electricity, followed by your Jeep 4xe charger, and finally, your Jeep 4xe charging system.
Jeep 4xe is not Charging – Check these first!
Here are some of the most common problems to help you diagnose your issue.
Incorrect insertion of the Jeep 4xe charging head.
When the charging head is inserted at the incorrect angle, and the con pin connecter is not making proper contact, then your Jeep 4xe will not charge; when testing various EV chargers, we found that Jeep hardware and software for charging have a low tolerance to errors during charging such as spec supply, voltage, waveform, etc. which might be impacted by not correctly inserting your Jeep 4xe charging head.
The simple solution is to start the charging process again, remove the Jeep 4xe charging head from the port, close the charging hatch, and start the process again. If the first solution doesn’t work, you might have dirt or debris that might prevent current flow in the charging port. We recommend inspecting the charging port or the Jeep 4xe charging head for any debris and removing them; another standard solution after trying all three solutions is to try and restart the Jeep 4xe.
NEMA plug-sharing circuit breaker with other devices
Another common issue is that you might have other devices sharing the circuit breaker with your Jeep 4xe charger. Another standard diagnostic is if your circuit breaker trips when charging your Jeep 4xe, which might also mean your connection is overloaded. You might also notice that your charging head will start overheating, and flashing yellow lights will start blinking on the EVSE, which means there is a grounding or overheating fault.
For this reason, your Jeep 4xe might start and stop charging or completely stop charging; we recommend first making sure that your charge power rating matches or exceeds the breaker capacity; we recommend a 50A 220v breaker connected to a level 2 charger.
If you are sharing a circuit breaker, we recommend that we use the Grizzl-E with a dedicated 50A 240v breaker, with adequately sized wires rated 40-50amps load, connected to a 240V 40amp outlet, and the charger charges perfectly.
We use an outlet tester to make sure the outlet is fine, and there is the correct power supply to the Jeep 4xe charger; this is all the item you need to make sure your outlet and wiring connection is working as they should:
Random voltage spikes or drops when charging your Jeep 4xe.
Another common problem is voltage spikes or drops when charging your Jeep 4xe; we first recommend checking what voltage you are getting; we use a Kill-A-Watt and will let you know how much power is being used by your home Jeep 4xe charger.
Test your Jeep 4xe home charger voltage
Now if you have a problem with voltage spikes or drops, which frequently happens with home chargers, you might experience a family of error codes (P0D-27) with the Jeeps 4xe system trying to protect itself from charging issues that may arise due to spikes or drops of voltage, some of the error codes reported to us include High Voltage System Interlock Circuit A (P0A0A), Implausible Data Received from TCM (U0402), HVIL Circuit Low (P0A0A, P1E73, P1E74)
The solutions to these errors are first seeing what voltage you are getting and making sure there are no significant voltage spikes or drops occurring in your home charging system, especially if you are using a Jeep charger extension cord; if you have tested with a Kill-A-Watt and the voltage is out of specs, contact the utility company to address the issue.
If your Jeep has thrown some error codes during the incident, you will need to clear the codes yourself using an OBD2 Scanner; we use the OBDLink MX+ that can connect to your phone or tablet; we recommend it for its compatibility with the 4xe and many of its module which enhance diagnostic of Jeep 4xe issues.
