Description

Technical Field

[0001] This utility model relates to the field of battery charging and discharging technology, and in particular to a charging and discharging system. Background Technology

[0002] Traditional power tool battery packs have evolved into multi-functional adapters to power 3C electronic devices such as mobile phones and tablets, as detailed in patent TWM584567U. These adapters charge the battery pack when connected to AC power and also feature a USB port for reverse power output when not connected to AC power, thus powering mobile phones, tablets, and other 3C electronic devices. However, with the development of new battery packs in the power tool industry, more and more tool battery packs are designed with built-in USB ports. Therefore, without a multi-functional adapter, the battery pack itself can power 3C electronic devices. This leads to functional overlap between these tool battery packs with built-in USB ports and multi-functional adapters; they only need to be compatible with a single-function charging adapter. In summary, powering 3C electronic devices with power tool battery packs is a major trend, leading to two common charging / discharging combinations / systems on the market: 1. A single-function adapter paired with a new battery pack with a built-in USB port; 2. A multi-functional adapter paired with a traditional battery pack without a USB port. In addition to the two common charging / discharging combinations / systems mentioned above, many more new charging / discharging combinations / systems are constantly being explored and developed to meet the diverse needs of users.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0033] This utility model embodiment provides a charging and discharging system, the structure of which is as follows: Figures 1 to 5 As shown, it includes battery pack 1 and adapter 2;

[0034] The battery pack 1 is provided with a power tool output interface 11 for supplying power to power tools and an adapter interface 12 for connecting adapter 2;

[0035] The adapter 2 is provided with a battery pack interface 21 for connecting the battery pack 1, a power input interface 22 for connecting an external power source, and a first USB interface 23 for outputting DC power.

[0036] Adapter interface 12 is used to connect to battery pack interface 21, and then

[0037] When the power input interface 22 is connected to an external power source, the battery pack 1 can be connected to the adapter 2 for charging; at the same time, the first USB interface 23 can be connected to an external 3C electronic device and powered by the external power source.

[0038] When the power input interface 22 is not connected to an external power source, the battery pack 1 can be connected to the adapter 2 to discharge and output its own power through the first USB interface 23.

[0039] The battery pack 1 is also equipped with a second USB port 13. When the battery pack 1 is connected to the adapter 2 and the power input port 22 is not connected to an external power source, the second USB port 13 is not blocked by the adapter 2, and the first USB port 23 is not blocked by the battery pack 1. This allows the power of the battery pack 1 to be output to the outside world through the first USB port 23 and the second USB port 13 at the same time, and can charge at least two 3C electronic devices at the same time.

[0040] In addition, when the power input interface 22 is connected to an external power source and the battery pack 1 is not connected to the adapter 2, the first USB interface 23 can also be connected to an external 3C electronic device to power it.

[0041] Optionally, the power tool output interface 11 and the adapter interface 12 are the same interface, that is, the power tool output interface 11 or the adapter interface 12 on the battery pack 1 is essentially a bidirectional interface that can be input / output.

[0042] In this embodiment, the interface for connecting the power tool and the adapter 2 on the battery pack 1 is the same, which saves the need to set up one interface on the battery pack 1, similar to most tool battery packs on the market.

[0043] Optionally, the power input interface 22 is an AC input interface and / or a DC input interface. When the power input interface 22 is an AC input interface, the adapter 2 needs to have a built-in AC to DC power module.

[0044] In this embodiment, the power input interface 22 is an AC input interface. The adapter 2 needs to be connected to the mains power with an AC power cord. For the adapter 2, there is no need to connect an external AC to DC power module. The adapter 2 has a higher degree of integration and stronger unity.

[0045] Optionally, the number of battery pack interfaces 21 is multiple, so that the adapter 2 can be connected to multiple battery packs 1 at the same time. In particular, when the power input interface 22 is not connected to an external power source, it can ensure that the entire system has more power available for 3C electronic devices.

[0046] In this embodiment, the number of battery packs 1 is preferably two. In this case, the adapter 2 can be understood as a dual-pack charger. This setting is the best solution after considering the size of the adapter 2 and the total available power of the system.

[0047] Optionally, the adapter 2 is also provided with a switching button 24. When the power input interface 22 is not connected to an external power source, the switching button 24 is used to control the output of the battery pack 1's power to the first USB interface 23. It can be understood that the function of the battery pack 1 to output its own power to the outside through the first USB interface 23 is activated only when the switching button 24 is pressed.

[0048] In this embodiment, the switching button 24 is provided to improve the safety of the charging and discharging system. In addition, when the switching button 24 is pressed, the discharge circuit of the battery pack 1 is actually in a dormant state, which can save some power consumption.

[0049] Optionally, the number of first USB ports 23 is multiple, including USB-A ports and / or USB-C ports, which can meet the charging needs of more 3C electronic devices.

[0050] In this embodiment, there are three first USB ports 23, including one USB-A port and two USB-C ports, which can be adapted to most 3C electronic devices on the market.

[0051] Optionally, at least one of the first USB interfaces 23 is a bidirectional input / output interface. When the first USB interface 23 is a bidirectional input / output interface, it can not only power 3C electronic devices, but also input power to charge the battery pack 1. At this time, the power input interface 22 can be connected to another power source or not connected to a power source.

[0052] In this embodiment, one USB-A interface is a bidirectional input / output interface, and two USB-C interfaces are unidirectional output interfaces. While satisfying the input / output functions of the first USB interface 23, the cost is reduced as much as possible.

[0053] Optionally, there may be multiple second USB ports 13, including USB-A ports and / or USB-C ports, to meet the charging needs of more 3C electronic devices.

[0054] In this embodiment, there are two second USB ports 13, both of which are USB-C ports.

[0055] Optionally, at least one of the second USB ports 13 is a bidirectional input / output port. When the second USB port 13 is a bidirectional input / output port, it can not only power 3C electronic devices, but also input power to charge the battery pack 1. At this time, the adapter port 12 can be connected to another power source or not.

[0056] In this embodiment, one of the two USB-C ports is a bidirectional input / output port, and the other is a unidirectional output port. The cost is minimized while still satisfying the input / output function of the second USB port 13.

[0057] Optionally, at least one second USB port 13 is connected to the battery pack 1 via a charging cable 14, one end of which is connected to the battery pack 1 and the other end is connected to a bidirectional input / output USB-C port.

[0058] In this embodiment, the built-in charging cable 14 of the battery pack 1 enables the battery pack 1 or the charging and discharging system to more conveniently power 3C electronic devices.

[0059] Optionally, the adapter 2 also includes a wireless charging module for wirelessly charging 3C electronic devices.

[0060] In this embodiment, the wireless charging module configured in adapter 2 can save the use of data cables, add a charging position, and provide another charging method for 3C electronic devices, thus meeting the diverse needs of users.

[0061] Optionally, the adapter 2 includes a first controller, and the external output of the first USB interface 23 is controlled by the first controller; the battery pack 1 includes a second controller, and the external output of the second USB interface 13 is controlled by the second controller.

[0062] Optionally, each interface between the adapter 2 and the battery pack 1 is equipped with a detection unit to detect the status of the battery pack 1 in real time.

[0063] In this embodiment, the state parameters of the battery pack 1 may include electrical parameters such as voltage and current. The charging and discharging state of the battery pack 1 can be fed back in real time by collecting these electrical parameters.

[0064] Optionally, the first controller and the second controller communicate with each other to synchronize the state of battery pack 1 in real time. The state of battery pack 1 can be reflected by measuring electrical parameters such as voltage and current at the interface.

[0065] In this embodiment, the states of the two battery packs 1 connected to the adapter 2 may differ. The states of the two battery packs 1 are synchronized in real time through communication between the first controller and the second controller, so that the charging and discharging of the battery packs 1 is more efficient.
