Abstract
The present disclosure discloses a quick battery charging system including a lithium secondary battery having a negative electrode porosity of 25 to 35% and a negative electrode loading amount of x. The system includes a storage unit which stores a lookup table for mapping first coefficient information of an upper bound condition associated with a C-rate of a charge current represented by a quadratic function and information associated with the negative electrode loading amount (x). The system includes a charging control apparatus which reads the information associated with the negative electrode loading amount (x) from the storage unit, determines the first coefficient information of the quadratic function representing the upper bound condition from the lookup table, determines the C-rate range of the charge current using the first coefficient information, and supplies the charge current satisfying the determined C-rate range to the lithium secondary battery.
