Abstract: A discharging control method and a charging control method for a battery pack control system are provides. The battery pack control system includes a master battery management unit and multiple slave battery management units. The master battery management unit controls the slave battery management units. The slave battery management units controls battery packs to connect to an operating circuit or disconnect from the operating circuit. In the discharging control method and the charging control method, a loop current generated from connecting a battery pack to an operating circuit is predicted each time before a slave battery management unit controls the battery pack to connect to the operating circuit, and the battery pack is controlled to connect to the operating circuit with the generated loop current within a safe value range.
