The invention provides a charging and discharging device, a charging and discharging control method thereof and flight equipment. The charging and discharging device comprises a plurality of battery packs and a second control unit. The plurality of battery packs are respectively located on a plurality of arms of the flight equipment. Each battery pack comprises a plurality of battery cell groups, a plurality of switch units arranged among the plurality of battery cell groups, and at least one first control unit; and the second control unit is located in the fuselage of the flight equipment, is connected with the at least one first control unit, and is used for controlling the connection or disconnection of the plurality of switch units through the at least one first control unit so as to control the series connection or parallel connection of the plurality of battery cell groups. The charging and discharging device can be charged in a high-voltage and small-current mode and discharged in a low-voltage and large-current mode, so that heating damage caused by large current in the charging process of the battery pack in the flight equipment is effectively avoided, and the service life of the battery pack is effectively prolonged.

    本申请提供了一种充放电装置及其充放电控制方法、飞行设备,该充放电装置包括多个电池组和第二控制单元。多个电池组分别位于飞行设备的多个机臂上。每个电池组包括多个电芯组、设置在多个电芯组之间的多个开关单元、以及至少一个第一控制单元。第二控制单元位于飞行设备的机身内,且与至少一个第一控制单元连接,用于通过至少一个第一控制单元控制多个开关单元的连通或断开来控制多个电芯组的串联或并联。本申请中的充放电装置能够以高电压小电流的方式进行充电,以低电压大电流的方式进行放电,因而有效避免飞行设备中的电池组在充电过程中因电流较大而造成的发热损坏,有效提高电池组的使用寿命。
