Abstract
A battery power table setting method for using battery power efficiently and preventing battery overcharge includes: a first table generation operation for generating a first table by measuring a maximum charging power that prevents an output of a battery from being more than a maximum allowable voltage when the battery having a predetermined SOC value is charged at a predetermined temperature for a predetermined time; a second table generation operation for generating a second table by measuring an SOC value at the time point that the battery reaches the maximum allowable voltage when the battery is charged with a predetermined power value at a predetermined temperature; a third table generation operation for generating a third table by calculating a second maximum charging power according to a predetermined temperature and a predetermined SOC value based on the second table; and a derating table generation operation for generating a derating table.
