Charging slow

Charging is slow - Reduced charging effect

Zaptec · Go

What does Charging slow mean?

The Zaptec Go charger is delivering a slower-than-expected charging speed. This can be due to various limiting factors in the electrical system or charger configuration.

Common Causes

  • Limitations imposed by the main power grid.
  • The circuit breaker's rating is too low or incorrectly set in the charger's configuration.
  • The charging cable or the vehicle's On-Board Charger (OBC) has a lower current capacity.
  • The charger is operating in Eco Mode, which intentionally reduces charging speed.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check the standalone current setting for the charger in the Zaptec App by repeating the 'Install Zaptec Go' procedure and ensure it's set to the correct maximum value.

  2. 2

    Review the installation and charger power management settings within the Zaptec Portal (zendesk.zaptec.com) to optimize charging parameters.

  3. 3

    Verify that your electrical installation and circuit breaker are rated to support the desired higher charging speed.

  4. 4

    Ensure your charging cable is rated for the maximum current you expect, and that Eco Mode is not inadvertently activated in the app.
