How to stop an electric car charger from frequently disconnecting?

 

Check and Secure the Charging Connector and Port

  One of the most common reasons your electric vehicle (EV) charger frequently disconnects can be loose or improperly seated connections. Inspect the electric car charging cable and connector and make sure it fits securely into both your car's charging port and the charging unit itself. If dirt, dust, or moisture is present within the connector or the port, clean carefully using a soft, dry cloth. Regularly verifying that connectors are undamaged, clean, and fully seated can significantly reduce instances of disconnections and interruptions.  

Inspect Charging Cable for Damage

  A compromised charging cable can frequently interrupt the charging process. Thoroughly examine your EV cable for visible physical damage like cuts, abrasions, worn insulation, or corrosion. A damaged or deteriorating cord is not only inconvenient but also poses a safety risk. If you find cable damage, consider replacing it immediately with an OEM (Original Equipment Manufacturer) or certified compatible cable.  

Avoid Overheating and Thermal Overload Issues

  EV chargers incorporate built-in protection mechanisms to handle overheating or overloading. A frequent disconnect might indicate your charger is experiencing thermal overload, particularly if you notice the cable, connectors or charging station getting excessively warm. Solutions include:

• Ensuring charging happens in a shaded, cooler area away from direct sunlight.
• Avoiding tightly coiled or bent cables which can build up heat during charging.
• Lowering your EV’s charge rate temporarily by adjusting charger settings (if your system allows charge rate adjustments).

 

Verify Proper Electrical Supply and Connections

  Intermittent power supply or electrical surges can trigger frequent charger disconnections. EV chargers require stable and sufficient power to function optimally. Confirm that your electrical panel and circuitry are properly rated for the EV charger’s capacity. If your home or commercial property experiences periodic electrical disruptions or irregularities, consulting a professional licensed electrician servicing St Louis or Nashville would be beneficial to stabilize your electrical infrastructure and avoid long-term charging interruptions.

• Check for adequate circuit breaker capacity aligned with your EV charger's specifications.
• Ensure your electric wiring and outlets meet standard EV charging requirements.
• If uncertain, engage professional electricians to inspect or upgrade electric components, ensuring reliable and secure charging.

 

Update Charger Software and EV Firmware

  Electric car chargers and vehicles often receive software updates to address glitches, enhance compatibility, and optimize charging performance. Outdated software or firmware could result in inconsistent charging behaviors and frequent disconnections. Consult your car manufacturer’s and charger manufacturer's online resources or contact the respective support lines for instructions on how to perform necessary updates.  

Assess Network and Connectivity Settings

  Smart EV chargers connected via Wi-Fi or cellular data might experience charge interruptions due to weak network signals or connectivity degradation. If your charger connects wirelessly, verify your Wi-Fi strength and stability:

• Place your wireless router closer or use a Wi-Fi extender to enhance signal coverage in your charging area.
• Consider utilizing wired connections wherever feasible for stable connectivity.
• Reset your router or modem if Wi-Fi connection appears to be disrupted.

 

Avoid Using Extension Cords and Adapter Plugs

  Using extension cords or unofficial adapters significantly increases the risk of disconnecting while charging your electric vehicle. These devices may introduce extra resistance in the circuitry, leading the charger to power down automatically as a safety measure. Always connect your EV charger directly into properly rated outlets or charging stations.  

Consider Quality and Compatibility Standards

  If charging problems continue even after looking at the above factors, consider the quality or compatibility of your charger hardware. Some vehicles may not reliably charge with certain aftermarket chargers or public charging stations. To operate smoothly, electric cars typically receive the best charging experience using OEM charging cables and station hardware tested and recommended by vehicle manufacturers.  

Consult a Professional Technician if Issues Persist

  When troubleshooting the EV charging interruptions proves unsuccessful or challenging, it's beneficial to consult with professional technicians experienced in EV charger installation and maintenance. A qualified electrician or EV charging specialist, especially in areas with established EV infrastructure like St Louis or Nashville, can provide diagnostics, expert advice, and precise solutions, ensuring consistent and reliable operation of your charging setup.
