    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.

    Abstract: A charging control method includes the following. (a) An electrical state of a battery set is obtained. (b) Whether the electrical state is greater than a first electrical state threshold is determined and charging control based on a first charging mode or a second charging mode on the battery set is performed accordingly. (c) During the charging control on the battery set, at least one temperature difference value is determined based on temperature values of the battery set at different times. (d) Whether the temperature difference value is greater than a first temperature difference threshold is determined and whether to temporarily stop or continue the charging is determined accordingly. (e) During the charging control on the battery set, the electrical state is obtained, and whether the electrical state satisfies a fully-charged criterion is determined and whether to stop or continue the charging control is determined accordingly.
