Abstract: A system for optimizing charging for a vehicle having a rechargeable energy storage unit and travelling on a route includes a controller. The controller has a processor and tangible, non-transitory memory on which instructions are recorded. Execution of the instructions by the processor causes the controller to obtain details of the route, including surveying local charging infrastructure to determine availability of one or more charging stations within a predefined radius of the route. The controller is adapted to obtain respective station parameters pertaining to the one or more charging stations. Based on user input, at least one session goal is selected from a predefined set of goals. The controller is adapted to generate a recommended charging profile respectively for one or more stops along the route, based in part on the session goal and the respective station parameters.

Abstract: 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.
