Abstract
A battery management apparatus includes a voltage sensor configured to measure a voltage of one or more battery cells, a control circuit configured to diagnose a defect in the one or more battery cells by determining a voltage change amount of the one or more battery cells using the voltage of the one or more battery cells measured by the voltage sensor, and a storage configured to store data and algorithms driven by the control circuit. The control circuit is configured to obtain a voltage for each battery cell by sequentially measuring the one or more battery cells, and to perform first voltage measurement on the one or more battery cells in a forward chronological order and to perform second voltage measurement on the one or more battery cells in a reverse chronological order.
