Abstract
There are provided a battery management apparatus, a battery management method and a battery pack. The battery management apparatus sets at least one of a plurality of external variables as a valid external variable for each internal variable using a plurality of input data sets associated with the external variables that can be observed outside a battery cell and a plurality of desired data sets associated with the internal variables that are not observed outside the battery cell.
Claims11
A battery management apparatus, comprising:
- a memory unit configured to store first to mth input data sets, first to nth desired data sets, and first to nth reference values, each of m and n being a natural number of two or greater;
- and
- a control unit operably coupled to the memory unit,
- wherein the first to mth input data sets are associated with first to mth external variables that are observable outside the battery cell, respectively,
- wherein each of the first to mth input data sets includes a predetermined number of input values,
- wherein the first to nth desired data sets are associated with first to nth internal variables, respectively,
- wherein the first to nth internal variables rely on a chemical state inside the battery cell, and are not observable outside the battery cell,
- wherein each of the first to nth desired data sets includes the predetermined number of target values, and
- wherein the control unit is configured to set at least one of the first to mth external variables as a valid external variable for each of the first to nth internal variables, based on the first to mth input datasets, the first to nth desired data sets, and the first to nth reference values.
