1. A vehicle comprising:

  • a battery haying a state of charge (SOC) and a maximum SOC setpoint; and

    at least one controller programmed tocharge the battery with power from an electric power grid electrically connected with the vehicle to a SOC setpoint defined by a difference between the maximum SOC setpoint and a net maximum increase in the SOC predicted for a next vehicle route that includes a regenerative event responsive to the SOC setpoint being greater than the SOC,discharge the battery to the electric power grid responsive to the SOC setpoint, defined by the difference between the maximum SOC setpoint and the net maximum increase in the SOC predicted for the next vehicle route that includes the regenerative event, being less than the SOC, andoperate the vehicle, from a beginning of the next route until transition to a charge sustaining mode of operation that results from the SOC intersecting a minimum SOC level, such that the battery is only charged via regenerative braking energy capture.
