摘要： A battery charging method and corresponding apparatus include charging a battery based on an initial charging operation, and verifying whether a change event, with respect to a charging operation, occurs based on the charging of the battery. The battery charging method and corresponding apparatus also include changing the charging operation to an adjusted charging operation in response to verifying that the change event, with respect to the charging operation, occurs. The change event includes a physical quantity event in which a physical quantity of the battery sensed during a charging rest time of the initial charging operation is greater than or equal to a threshold physical quantity.

摘要： To generate a charging path for a battery, a method includes generating simulation data for charging currents based on a battery model indicating an internal state of a battery, generating an initial look-up table (LUT) for the charging currents and preset battery voltage limits based on the simulation data, the initial LUT representing initial charging limit conditions of the battery for stages corresponding to the charging currents, generating a modified LUT by adjusting at least one of the initial charging limit conditions of the initial LUT, in response to the initial LUT failing to satisfy a threshold, determining a final LUT based on the modified LUT, in response to the modified LUT satisfying the threshold, and generating a charging path for the battery based on the final LUT.
