APPARATUS AND METHOD FOR ESTIMATING DETERIORATION OF BATTERY PACK

摘要

An apparatus for estimating a deterioration may include a battery pack, a state information sensing unit configured to sense a state of the battery pack to generate state information, a conversion operation unit configured to convert into an open circuit voltage (OCV) using the generated state information and estimate a state of charge (SOC) using the converted OCV, a first SOH estimation operation unit configured to estimate a first state of charge (SOH) using the estimated SOC, a battery aging factor calculation unit configured to calculate a battery aging factor using the estimated SOC, a second SOH operation unit configured to apply the calculated battery aging factor to a preset lookup table to calculate a second SOH, and a filtering unit configured to filter the first SOH and the second SOH to generate a final SOH.

1. An apparatus for estimating deterioration, comprising:
a battery pack; a state information sensing unit configured to sense a state of the battery pack to generate state information; a conversion operation unit configured to convert into an open circuit voltage (OCV) using the generated state information and estimate a state of charge (SOC) value using the converted OCV; a first SOH estimation operation unit configured to estimate a first state of charge (SOH) value using the estimated SOC value; a battery aging factor calculation unit configured to calculate a battery aging factor using the estimated SOC value; a second SOH operation unit configured to apply the calculated battery aging factor to a preset lookup table to calculate a second SOH value; and a filtering unit configured to filter the first SOH value and the second SOH value to generate a third SOH value.
