SYSTEM FOR PREDICTING LIFETIME OF BATTERY

摘要

PURPOSE: A system for estimating the life time of a battery is provided to determine a design error before producing a battery cell. CONSTITUTION: A battery life time estimating system (1000) includes a learning data input unit (110), a target data input unit (120), a machine learning unit (210), and a life time estimating unit (220). The learning data input unit receives a learning measurement factor or a learning factor specific to a pre-produced learning battery cell. The target data input unit receives a target factor for a target battery cell in order to estimate the life time of the battery cell. The machine learning unit is connected to the learning data input unit, and gives a weight to each of the learning factors which are input through the learning data input unit. The life time estimating unit is connected to the target data input unit or the machine learning unit, and uses the weight applied by the machine learning unit in order to estimate estimation characteristics showing the life time of the target battery cell.
