If your EV charger is blinking red, it typically indicates a fault or error. This warning sign should not be ignored as it can affect the charging process.
When an electric car charger displays a red light, it often signals a problem that needs immediate attention. This could range from a simple issue like a loose connection to more complex faults in the charger or the vehicle’s charging system. For lithium battery chargers, a blinking red light usually points to issues such as overheating, overcharging, or a potential fault with the battery itself. It’s essential to refer to the specific user manual for precise troubleshooting steps.
EV charger faults can vary. A steady red light might indicate a different issue than a blinking one. For instance, in the case of a Polestar charger flashing red, it could be a sign of a communication error between the charger and the vehicle. Similarly, power wheelchair and gel blaster chargers flashing red often denote a charging error or a battery fault. It’s crucial to understand the specific meanings of these indicators for your device.
In some cases, the red light could simply mean the battery is charging, and it will turn green or off when the battery is fully charged. However, if the light is blinking, it’s advisable to consult the manual or contact customer support for your specific charger model.
For a more detailed understanding of what a red light on your EV or battery charger means and how to address it, we invite you to read the detailed article below. This will provide you with a deeper insight into the potential issues and their solutions.
