What Does the Blue Light on the Tesla Wall Charger Mean?

As Tesla owners embrace the convenience of home charging, the subtle nuances of the charging experience can sometimes raise questions.

A notable query that has surfaced revolves around the Tesla Wall Charger’s indicator light, particularly when it shifts from the familiar solid green to a solid blue.

In this article, we aim to demystify the meaning behind the blue light on the Tesla Wall Charger, providing clarity on its purpose and alleviating any concerns users may have.

The Scenario

Imagine the scenario: You, accustomed to the routine of seeing a solid green light when their vehicle is fully charged, notice an unexpected change to a solid blue light. Naturally, this prompts an inquiry into the significance of this shift in color.

Typically we associate a green light with a fully charged vehicle.

The solid blue light on the Tesla Wall Charger is indicative of the vehicle’s readiness or standby state. This state is often linked to scheduled charging or preparation for departure based on the user’s defined settings.

Essentially, the blue light communicates that the vehicle is not actively charging at that moment but is poised to do so according to the preset schedule.

Comparing with the Solid Green Light

To further contextualize this transition, it’s essential to understand the role of the solid green light. Historically, a solid green light on the charging port signifies that charging is complete.

The shift from green to blue, therefore, is not a cause for concern. Rather, it is a clear indication of the charging system’s readiness and adherence to the user’s scheduling preferences.

Managing the Blue Light

Now, let’s address what you can do to manage the blue light. If you find yourself wanting to return to the familiar solid green light, consider reviewing your scheduled charging or departure settings.

Adjusting these settings to align with your preferences can influence when the vehicle actively charges, potentially altering the color of the charging port light.
