Abstract: A charge system and corresponding method for maintaining an available state-of-charge above a predetermined threshold during an extended charging session and/or restarting a charging session if said charging session terminates and the resulting available state-of-charge remains below the predetermined threshold. Additionally, a charge system and corresponding method for tracking metrics of a charge session to allow for accessibility in reviewing and/or troubleshooting charging session-related events.

Abstract: A control system for controlling a powertrain of an electric or hybrid electric vehicle is disclosed. The powertrain comprises a battery and a traction motor and is operable in a regenerative braking mode. The control system is configured to generate a deceleration target for the vehicle in the regenerative braking mode, and to generate a torque command for the traction motor based on the deceleration target. By generating a deceleration target for the vehicle during regenerative braking and using the deceleration target to control the torque of the traction motor, more consistent regenerative braking may be provided, particularly when the vehicle is used to carry different loads.

Abstract: Methods, apparatuses, and systems for controlling regenerative braking of a vehicle are disclosed. A user interface facilitates a user to provide an input to select an operating mode for the vehicle, the operating mode selected from one of selectable modes comprising: (i) manually controlled regenerative braking mode and (ii) automatically controlled regenerative braking mode. When the (i) mode is selected, the controller applies a scaling factor to the regenerative torque capability curve of the vehicle based on additional user input. When the (ii) mode is selected, the controller automatically applies the scaling factor based on one or more traction control events and environmental factors.
