For safe EV charging, your electric vehicle is equipped with essential earthing safety features, as recommended by the EV manufacturer. These systems typically require an earthing resistance of 5 ohms or better for proper and safe operation. Importantly, lower resistance values indicate better earthing. WunderCurrent EV chargers are engineered to typically provide an even lower earthing resistance, averaging around 3 ohms. This superior grounding capability ensures an extra margin of safety and optimal charging performance. Be aware that if the earthing resistance slightly exceeds the recommended threshold, such as 5.1 ohms, your EV’s safety systems may prevent charging and could display a grounding error. If you encounter a grounding error, WunderCurrent will assist you in charging your EV with an external earthing mechanism.
