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.
Claims16
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.
A system for estimating a remaining useful life (RUL) of a battery, the system comprising:
- an RUL estimator;
- and
- a non-volatile memory comprising instructions,
- wherein the instructions are configured to cause the RUL estimator to:
- identify a class of data of the battery in real time;
- determine whether a second level RUL estimation is set for the class;
- estimate 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
- estimate a fine RUL of the battery in response to the second level RUL estimation being set for the class.
A remaining useful life (RUL) estimator, comprising:
- a processor;
- a classifier implemented by the processor and configured to identify a class of data of a battery in real time;
- a state of health (SOH) monitor implemented by the processor and configured to determine whether a second level RUL estimation is set for the class;
- a regression analyzer implemented by the process and configured to
- estimate 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
- estimate a fine RUL of the battery in response to the second level RUL estimation being set for the class.
