BATTERY MONITORING APPARATUS AND BATTERY MONITORING METHOD |
摘要 |
A battery monitoring apparatus that monitors a state of a battery for driving an electric motor includes: a voltage measuring unit configured to measure an analog voltage of each of battery cells; an A/D converter configured to convert the measured analog voltage of each of the battery cells to a digital voltage; a filter configured to perform filtering on the digital voltage converted by the A/D converter; and a control unit configured to receive a cell voltage from the A/D converter or from the filter depending on a change in battery cell voltage and/or a battery use time. The battery monitoring apparatus has advantages in that measurement precision can be increased while data rate is maintained by employing a hybrid filter which is a combination of an average filter and an IIR filter, so that the measurement precision can be increased with minimum additional cost. |
