1. A method for operating a battery system comprising:
storing battery charge usage data for a plurality of days in a memory;
obtaining usage data for a current day based on a past corresponding day;
comparing the usage data for the current day to a plurality of thresholds;
when the usage data is less than a first usage threshold, setting an operating state of charge range for the current day to a first state of charge range;
when the usage data is between the first usage threshold and a second usage threshold, setting the operating state of charge range for the current day to a second state of charge range greater than the first state of charge range;
when the usage data is greater than the second usage threshold, setting the operating state of charge range for the current day to a third state of charge range greater than the second state of charge range; and
charging and discharging the battery system based on the state of charge range during the current day.
