摘要:
One or more embodiments provide a charging control device including a storage device configured to store tables defining a correlation between a change in capacity and a change in voltage of a cell, and map and store lifespan states and temperatures corresponding to the tables, and a control device configured to obtain a table corresponding to a current state of a battery module from the tables based on a lifespan state and a temperature of the battery module at a charging start time point, obtain a predicted voltage value for the battery module using the table and an accumulated current amount obtained by accumulating charging currents detected while charging is in progress, and control a charging current according to a comparison result of comparing a measured voltage value that is measured in the battery module with the predicted voltage value.
