1. A battery management apparatus, comprising:
- a battery information collector, implemented by a processor or a computer, configured to collect battery information;
a capacity estimator, implemented by a processor or a computer, configured to estimate residual capacity of a battery at an operating temperature based on the collected battery information;
a capacity converter, implemented by a processor or a computer, configured to convert the estimated residual capacity of the battery into capacity of the battery at a reference temperature; and
a state of health (SOH) estimator, implemented by a processor or a computer, configured to estimate SOH of the battery based on the converted capacity.

Abstract
A battery management apparatus and method to estimate a state of a battery is provided. The battery management apparatus includes a processor configured to collect battery information, to estimate a residual capacity of a battery at an operating temperature based on the collected battery information, to convert the estimated residual capacity of the battery into a capacity of the battery at a reference temperature, and to estimate a state of health (SOH) of the battery based on the converted capacity.

10. A battery management method employing a capacity estimator implemented by a processor or a computer, a capacity converter implemented by a processor or a computer, and a state of health (SOH) estimator implemented by a processor or a computer, the method comprising:
-
estimating, using the capacity estimator, a residual capacity of a battery at an operating temperature based on collected battery information; converting, using the capacity converter, the estimated residual capacity of the battery at the operating temperature into a capacity of the battery at a reference temperature; and estimating, using the SOH estimator, a state of health of the battery based on the converted capacity. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
