Host system with AC charging inlet and method for identifying an electrical device connected thereto

A controller of a host system executes a method for detecting an external AC electrical device. While an AC charging inlet of the host system is electrically connected to the device via different vehicle-to-live (V2L) and jump-charge connections, the controller detects a control pilot voltage and a proximity voltage. When the control pilot voltage is 0V, the controller determines whether entry conditions are satisfied indicative of a desire to offload power from the host system to the device. When the entry conditions are satisfied, the proximity or control pilot voltage are modulated to generate a modulated voltage signal, which the controller compares to an expected voltage indicative of the device. Power is offloaded to the device when the modulated voltage signal matches the expected voltage.
