Embodiment 1

[0100] This embodiment provides a charging and discharging control method for a battery pack, which is applicable to mobile electronic devices such as mobile phones and IPADs, unmanned aerial vehicles, electric vehicles, and other devices with battery packs for power supply, such as figure 1 As shown, the charging and discharging control method of the battery pack includes the following steps:

[0101] S1. Judging whether a battery pack is detected; when a battery pack is detected, proceed to step S2; when a battery pack is not detected, control to disconnect all circuits. Preferably, judging whether a battery pack is detected can be judged based on the voltage at the access point. When a battery pack is connected, since the battery pack itself always has a certain amount of power, the The voltage will increase, so that it can be judged that a battery pack is connected.

[0102] S2. Determine whether the number of battery packs currently connected is greater than or equal to ...

Embodiment 2

[0131] Corresponding to Embodiment 1, this embodiment provides a charging and discharging control device for a battery pack, such as image 3 shown, including:

[0132] A first judging unit 1, configured to judge whether a battery pack is detected;

[0133] The second judging unit 2 is configured to judge whether the number of battery packs currently connected is greater than or equal to 2 when battery pack access is detected;

[0134] The multi-battery pack charging / discharging unit 3 is used to perform multi-battery pack charging / discharging mode when the number of currently connected battery packs is greater than or equal to 2.

[0135] The charging / discharging unit 4 of the single battery pack is used for performing the charging / discharging process of the single battery pack when the number of currently connected battery packs is less than 2.

[0136] The battery pack charge and discharge control device described above selects the battery pack charge / discharge mode by ju...

Embodiment 3

[0159] This embodiment provides a charging and discharging control system for a battery pack, including a memory and a processor, and the processor is used to read instructions stored in the memory to execute the steps of the method for controlling the charging and discharging of a battery pack in Embodiment 1.

[0160]Those skilled in the art should understand that the embodiments of the present invention may be provided as methods, systems, or computer program products. Accordingly, the present invention can take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) having computer-usable program code embodied therein.

[0161] The present invention is described with reference to flowch...

Abstract

The invention discloses a charging-discharging control method and device of a battery pack and a balanced charging and discharging box, and belongs to the technical field of balanced charge and discharge. The balanced charging and discharging box comprises a fuse inserting port, an AC-DC converter, a back-flow preventer, a battery pack charging and discharging control device and at least two charging-discharging jacks, wherein one end of the fuse inserting port is connected with a 220V AC joint, and the other end of the fuse inserting port is connected with the input end of the AC-DC converter; the output end of the AC-DC converter is connected with the first input end of the back-flow preventer; the second input end of the back-flow preventer is connected with a 10-32V DC joint, and the output end of the back-flow preventer is connected with the first input end of the battery pack charging and discharging control device; the first output end of the battery pack charging and discharging control device is connected with all the charging-discharging jacks; and the charging-discharging jacks are connected with a battery pack. According to the invention, multiple battery packs can be charged and discharged simultaneously, the fuse inserting port is additionally arranged to overcome the defect that the box needs to be returned to a factory or discarded when a fuse is burned out, and temperature protection and display of charging time are realized.

Description

technical field [0001] The invention relates to the technical field of balanced charging and discharging, in particular to a battery pack charging and discharging control method, device and balanced charging and discharging box. Background technique [0002] The application of battery packs in the market is becoming more and more extensive. For example, electric vehicles, hybrid vehicles and other models currently use power battery packs as energy sources in whole or in part in order to reduce energy consumption and exhaust emissions. Most of the portable equipment such as portable welding machines and cutting machines also use battery packs as the power supply to facilitate movement. Mobile electronic devices such as mobile phones and IPADs are also powered by battery packs. Therefore, the charging / discharging technology of the battery pack is more and more widely used, which will affect the service life of the battery pack and other indicators. [0003] However, most of ...
