METHOD AND APPARATUS FOR AUTOMATICALLY ESTIMATING REMAINING USEFUL LIFE (RUL) OF BATTERY IN REAL TIME
First Claim
Patent Images
1. A method of estimating a remaining useful life (RUL) of a battery, the method comprising:
- identifying a class of data of the battery in real time;
determining whether a second level RUL estimation is set for the class;
estimating a gross RUL by performing a first level RUL estimation in response to the second level RUL estimation not being set for the class; and
estimating a fine RUL of the battery in response to the second level RUL estimation being set for the class.

Abstract
A method of estimating a remaining useful life (RUL) of a battery includes: identifying a class of data of the battery in real time; determining whether a second level RUL estimation is set for the class; estimating a gross RUL by performing a first level RUL estimation in response to the second level RUL estimation not being set for the class; and estimating a fine RUL of the battery in response to the second level RUL estimation being set for the class.
