The present disclosure provides a method and system for ground fault detection. The method may include obtaining an input voltage and a null-ground voltage; determining whether the null-ground voltage is less than a voltage threshold; if yes, further determining whether the null-ground voltage is less than a preset voltage; if yes, determining that the grounding state is normal; if the null-ground voltage is greater than or equal to the preset voltage, determining that the grounding state is abnormal; if the null-ground voltage is greater than or equal to the voltage threshold, determining that the live wire and the null wire are reversed; in the case that the live wire and the null wire are reversed, determining whether the difference between the input voltage and the null-ground voltage is less than the preset voltage; if yes, determining that the grounding state is normal; if no, determining that the grounding state is abnormal.

A system and method are provided for a feed-forward control of an inverter to reduce, and potentially minimize, a DC link capacitor of a wireless power transfer system. The feed-forward control may be utilized to reduce the capacitance of the DC link capacitor in a single-phase series-series compensated WPT system.

A computer-implemented method for increasing safety during charging of a vehicle battery of a vehicle by a charging station, the method comprising the steps of calculating a forecast value for a maximum safe charging current by the controller of the vehicle based on sensor data generated by sensors of the vehicle and adjusting the charging current provided by the charging station in response to the forecast value of a maximum safe charging current.

Systems and methods may coordinate and provide bidirectional energy transfer events between electrified vehicles and other vehicles, devices, and/or structures. A power outage map can automatically be generated in response to a power outage condition of a grid power source. Both a power outage zone and a predicted power outage zone may be identified within the power outage map. A notification, alternative drive route recommendation, etc. may be sent to users of the bidirectional energy transfer system who are operating their vehicles near the power outage zone or the predicted power outage zone.
