1. A vehicle comprising:

  • a battery having a battery electrical storage capacity and a state of charge;

    an electrical motor, connected to the battery, to provide motive force;

    a controller to provide battery state of charge, ambient temperature, and vehicle-off time;

    a display to provide data representing a display image presenting information related to a battery-capacity-degradation state;

    a display generator to generate visual data for display in the display image to provide visual stimulation, representing the battery-capacity-degradation state, which is based on the state of charge (SOC), ambient temperature, and vehicle-off time, and user selected options to reduce battery capacity degradation, to the user;

    wherein the battery has a battery type and the visual data is based on usage data of the vehicle and the battery type; and

    wherein the display generator generates a visual display from the visual data using the vehicle off time that includes extended vehicle parking time and the controller sets a charging time of the battery based on the extended vehicle parking time, a current SOC, a battery degradation indication as a function of the current SOC and temperature, and a desired SOC for the next vehicle usage.
