This article addresses common reasons why owners of the Electric Mini may experience reduced charging speeds when using the zappi or another AC charger.
Overview
Many Electric Mini owners have reported that when they plug in their car to a zappi or another AC charger, they are not achieving the expected 7 kW charge rate. To diagnose this issue, check the Menu > Readings on the zappi. If the MIN PWM shows 53%, the zappi is offering a full charge speed to the vehicle (7 kW at 230 V). A lower PWM rate might indicate an issue. Below, we explore two common reasons for this problem.
Reason 1: Vehicle Settings
We have found that Electric Mini vehicles often come from dealerships set to a slower charge rate. Fortunately, this is a quick fix from myenergi’s perspective.
- Check Vehicle Settings: The menu for adjusting the charging rate is typically found within the charging current settings on the vehicle’s display.
- Set Charging Cable Mode to MAX: Ensure the charging cable mode is set to MAX to allow for maximum charging speed.

Reason 2: Charging Cable Specification
Another common issue is the use of a charging lead that does not support the full charging capacity of the zappi.
- Check Charging Cable Rating: Many vehicles are supplied with a 16-amp cable, which limits charging to approximately 3.6 kW.
- Use a 32-Amp Cable: To achieve the full 7 kW charging rate, ensure your charging lead is rated at 32 amps. This rating is usually indicated on the plug.
Conclusion
To maximise your Electric Mini’s charging speed, ensure that both the vehicle settings and the charging cable are configured correctly. The zappi is capable of providing up to 32 amps (7 kW), so verifying these aspects can help resolve charging speed issues.
