Abstract: A method and apparatus of detecting the states of a battery involve passing test-oriented charging and discharging pulse pair to a battery under test, and retrieving parameters of the battery, such as voltage, current, and temperature, which respond to the charging and discharging pulse pair, so as to estimate the battery states. The battery states include information pertaining to open-circuit voltage, internal resistance, capacitance, state of charge, and state of health of the battery. The battery state-related information is conducive to quick battery state detection and grading.
