1. An energy storage system, comprising:

  • a capacitor system comprising one or more capacitors;

    a charging circuit configured to charge the capacitor system to a first target voltage; and

    a controller configured to detect a first condition and programmed, in response to the first condition, to instruct the charging circuit to charge the capacitor system to a second target voltage that is less than the first target voltage, and to provide a notification that the capacitor system is operating in a degraded state,wherein the controller is configured to select the value of the second target voltage based upon a type of the first condition.
