System And Method For Controlling The State Of Charge Of A Battery To Increase The Useful Life Of A Battery Pack
26 May 22
A method and system for operating a battery system includes 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 threshold, when the usage data is less than a first usage threshold, setting an operating state of charge range for the current 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 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 to a third state of charge range greater the second state of charge range, and charging and discharging the battery system based on the state of charge range during the current.
