US 12,761,280 B2 · Diagnosis device and method for battery system

Abstract

A diagnosing apparatus and method for diagnosing a failure of a component included in a battery system may monitor whether an abnormal state of the component occurs based on abnormal state data of the component, upon abnormal state occurring in the component, measure a time duration for which the abnormal state is maintained, compare the time duration for which the abnormal state is maintained to a preset reference time duration, and, upon the time duration for which the abnormal state is maintained being shorter than the reference time duration, check whether a predetermined early stage diagnosis condition is satisfied based on the time duration for which the abnormal state is maintained, and determine whether or not a component failure has occurred according to whether or not the early stage diagnosis condition is satisfied.

Dependent claims

A method of diagnosing a battery system, the method comprising:

monitoring whether a component included in the battery system is in an abnormal state based on abnormal state data of the component;
in response to the component being in the abnormal state, measuring a time duration for which the component is in the abnormal state;
comparing the time duration for which the component is in the abnormal state to a preset reference time duration;
and
in response to the time duration for which the component is in the abnormal state being shorter than the reference time duration, determining whether a predetermined early stage diagnosis condition is satisfied according to the time duration for which the component is in the abnormal state and determining whether or not a component failure has occurred based on to whether or not the early stage diagnosis condition is satisfied.

2 more elements

An apparatus of diagnosing a battery system, the apparatus comprising:

at least one processor;
and
a memory configured to store instructions executed by the at least one processor,
wherein the instructions cause the at least one processor to:
monitor whether a component included in the battery system is in an abnormal state based on abnormal state data of the component;
in response to the component being in the abnormal state, measure a time duration for which the component is in the abnormal state;
compare the time duration for which the component is in the abnormal state to a preset reference time duration;
and
in response to the time duration for which the component is in the abnormal state being shorter than the reference time duration, determine whether a predetermined early stage diagnosis condition is satisfied according to the time duration for which the component is in the abnormal state and determining whether or not a component failure has occurred based on to whether or not the early stage diagnosis condition is satisfied.
