Abstract: Responsive to a user request, a controller operates an engine of a vehicle while parked to charge a traction battery to a target state of charge that exceeds a maximum state of charge limit, used during drive of the vehicle by an electric machine, in advance of a predefined period of time.

Abstract: Charging guidance systems and methods for charging electrified vehicles may be configured to influence a user’s charging decisions in a manner that simplifies the vehicle charging experience. Exemplary charging guidance systems may be configured to coach the user to charge a traction battery pack of the vehicle at a lower level charging option as opposed to a higher level charging option. Charging at lower level charging options when certain conditions are met reduces the amount of times the vehicle is charged using more aggressive charging methodologies, thereby improving battery performance, reducing costs, and preserving the life/warranty and asset utilization of the traction battery pack over the entire usage life of electrified vehicles.

Abstract: A vehicle power testing system is described. The power testing system may provide power testing that displays maximum simultaneous power usage for multiple auxiliary devices drawing power from the vehicle power generation system over a span of time. The power testing system may initialize a power test using a simple user interface, determine a number of auxiliary devices predicted to be connected to the power generation system at a future time, and generate a power simulation profile for the multiple connected auxiliary devices. The power testing system may generate an indication of maximum aggregate power usage and an alert message indicating that multiple auxiliary devices may be simultaneously used while connected to the vehicle power generation system based on an aggregate power rating associated with the vehicle power generation system.

Abstract: A vehicle and control method include a traction battery having a first nominal voltage, an auxiliary battery having a second nominal voltage, a bi-directional voltage converter configured to convert voltage between the first nominal voltage and the second nominal voltage, an electric machine powered by the traction battery and configured to provide propulsive power to the vehicle, an internal combustion engine, a plurality of electric accessories, and a controller programmed to control the DC/DC converter and the electric machine to supply power from the auxiliary battery through the DC/DC converter to the electric machine for a specified period of time in response to electric machine power demand being between a first threshold and a second threshold, and to reduce power supplied to at least one of the plurality of electric accessories in response to the electric machine power demand exceeding the second threshold.
