1. A processor-implemented method of an electronic device, comprising:
generating relative cumulative cell resistance (RCCR) curve information of a target battery based on constant voltage (CV) phase data of the target battery recorded during a charging operation of the target battery; and
generating at least one of aging or shorting condition information of the target battery based on the generated RCCR curve information.
