Abstract
Official abstract text for this publication.
A battery state estimation method and apparatus are provided. Sensing data of a battery is received, and feature information is acquired by preprocessing the sensing data. The preprocessed sensing data is selected based on the feature information, and state information of the battery is determined based on at least one of the selected preprocessed sensing data or previous state information of the battery.
First claim
Opening claim text (preview).
What is claimed is: 1. A battery state estimation method comprising: receiving sensing data of a battery; preprocessing the sensing data; calculating a difference value between each of sample values of the preprocessed sensing data and an adjacent sample value of the each of the sample values; determining statistic information of the calculated difference values; determining whether the preprocessed sensing data is suitable for battery state estimation based on the determined statistic information; determining state information of the battery based on the preprocessed sensing data in response to the preprocessed sensing data being suitable for the battery state estimation; and determining the state information based on a previous state information of the battery in response to the preprocessed sensing data not being suitable for the battery state estimation. 2. The battery state estimation method of claim 1 , wherein the statistic information comprises a variance of the calculated difference values. 3. The battery state estimation method of claim 1 , wherein the preprocessing of the sensing data comprises: filtering the sensing data; and downsampling the filtered sensing data. 4. A non-transitory computer-readable storage medium storing instructions, that when executed by a processor, causes the processor to perform the battery state estimation method of claim 1 . 5. A battery state estimation apparatus comprising: a memory; and a controller coupled to the memory, wherein the controller is configured to receive sensing data of a battery, preprocess the sensing data, calculate a difference value between each of sample values of the preprocessed sensing data and an adjacent sample value of the each of the sample values, determine statistic information of the calculated difference values, determine whether the preprocessed sensing data is suitable for battery state estimation based on the determined statistic information, determine state information of the battery based on the preprocessed sensing data in response to the preprocessed sensing data being suitable for the battery state estimation, and determine the state information based on a previous state information of the battery in response to the preprocessed sensing data not being suitable for the battery state estimation. 6. The battery state estimation apparatus of claim 5 , wherein the statistic information comprises a variance of the calculated difference values. 7. The battery state estimation apparatus of claim 5 , wherein the controller is further configured to: filter the sensing data; and downsample the filtered sensing data.
