At present, the number of shared electric bicycles is rapidly increased as the shared electric bicycles are rapidly popularized throughout the country. On the premise of ensuring the normal running of the vehicle, the number of the batteries is more than 2 times of the number of the vehicles, so that the number of the batteries is quite large. In this regard, the vehicle battery is typically charged by a charging cabinet having a plurality of charging compartments. However, if the battery is charged for a long time, there is a high safety risk, which also causes a waste of charging resources, and there is not enough charging grid to store the battery, which also causes a safety risk.

In view of the above, an embodiment of the present invention provides a charging cabinet, as shown in fig. 1, the charging cabinet includes: the charging module 100, the main control module 200 and the at least one switching module 300; the switching module 300 has a plurality of charging channels 300a, and each charging channel 300a is electrically connected with an interface 400; the charging module 100 is used for transmitting electric energy to the interface 400 through the charging channel 300 a; the main control module 200 is configured to control opening and closing of each charging channel 300a, so as to switch the working mode of the corresponding interface 400, where the working mode includes a charging mode and a non-charging mode. It is understood that the non-charging mode can also be regarded as a power storage mode, i.e. a mode in which the battery is stored and electric energy is stored to the battery.

The charging cabinet is used for charging electrical equipment, including but not limited to vehicles such as electric automobiles and electric bicycles. The interface 400 on each charging channel 300a may be electrically connected to a battery of the vehicle, so as to charge the battery of the vehicle. When the charging module 100 charges the battery of the vehicle through the interface 400, the interface 400 may determine as being in the charging mode; when the charging module 100 stops electrically charging the battery of the vehicle through the interface 400, the interface 400 may determine to be in the non-charging mode.

As an example, the interface 400 includes at least one of TYPE-A, TYPE-C, TYPE-micro, and the like.

As an example, the number of the switching modules 300 is plural, and the plural switching modules 300 are connected in parallel.

As described above, in the charging cabinet, when the main control module 200 detects that the battery is fully charged during the process of charging the battery by the interface 400, the charging channel 300a corresponding to the interface 400 in the switching module 300 is disconnected, so that the charging module 100 stops charging the battery through the interface 400, and the operation mode of the interface 400 is switched from the charging mode to the non-charging mode, and the fully charged battery can be stored in the charging cabinet. Therefore, the charging cabinet can automatically realize the switching between the charging mode and the non-charging mode of the interface 400, thereby increasing the function of battery storage, reducing the risk of battery storage, ensuring the safety of the battery, greatly reducing the storage cost of the battery and meeting the business requirements under the condition of meeting the storage requirements of the business battery; under the condition of the same quantity requirement of the interfaces 400, the plurality of interfaces 400 share one charging module 100 and one switching module 300, so that the utilization rates of the charging module 100 and the switching module 300 are improved, the quantity of the charging module 100 and the switching module 300 is obviously reduced, and the production cost of the whole cabinet is reduced.

In some embodiments of the present invention, the main control module 200 includes a detection unit, a determination unit and a trigger unit; the detection unit is used for acquiring and sending the charging amount or the temperature of the charged object to the judgment unit; the judging unit is used for judging whether the charged object is fully charged or whether the temperature is greater than a temperature threshold value and sending a judgment result to the triggering unit; the triggering unit is used for triggering an electric signal to the switching module 300 when the charged object is fully charged or the temperature is greater than the temperature threshold, so as to disconnect the corresponding charging channel 300 a. It is understood that the charged object includes a power storage device such as a battery. As an example, the main control module 200 may be configured to control the opening and closing of the charging channel 300a corresponding to the interface 400 based on how much power the interface 400 supplies to charge the battery of the vehicle. Specifically, when the main control module 200 detects that the battery of the vehicle is fully charged, the charging channel 300a corresponding to the interface 400 is disconnected, and at this time, the operating mode of the interface 400 is switched from the charging mode to the non-charging mode; on the contrary, when the main control module 200 detects that the battery of the vehicle is not fully charged, the charging channel 300a corresponding to the interface 400 is continuously closed, and at this time, the operation mode of the interface 400 is still the charging mode. In which, how the main control module 200 determines whether the battery of the vehicle is fully charged may be determined according to the magnitude of parameters such as current and voltage. As an example, the main control module 200 may be configured to control the closing and opening of the charging channel 300a corresponding to the interface 400 based on the temperature of the object to be charged.

Optionally, the charging cabinet further includes a plurality of grid plates, and each grid plate is configured to obtain parameters of voltage, current, temperature, and the like of the battery, and transmit the parameters to the main control module 200.

In some embodiments of the utility model, the switching module 300 comprises a relay. Further, as shown in fig. 2, the relay includes a plurality of sets of contacts 310 and a plurality of coil assemblies 320, each set of contacts 310 is electrically connected to the charging module 100 and the corresponding interface 400 to form a charging channel 300a, and each coil assembly 320 is electrically connected to the main control module 200 and is used for controlling the attraction or separation of the corresponding set of contacts 310. The relay may be a normally closed relay, and before the main control module 200 does not transmit an electrical signal to the coil assembly 320, the contacts 310 of the group corresponding to the coil assembly 320 are normally closed, so that the charging channel 300a corresponding to the coil assembly 320 is also in a closed state, and then the interface 400 corresponding to the charging channel 300a charges the battery; when the main control module 200 detects that the battery is fully charged, an electrical signal is transmitted to the coil assembly 320, and the armature 321 of the coil assembly 320 acts to separate the corresponding set of contacts 310, so as to cut off the charging channel 300a corresponding to the coil assembly 320, thereby stopping charging the battery through the interface 400 corresponding to the charging channel 300 a.

The number of the coil assemblies 320 in each switching module 300 may be the same as the number of the interfaces 400, and the number is not limited to a specific number, and may be selected according to requirements, for example, 2 or 3 are provided.

In some embodiments of the present invention, as shown in fig. 1, the charging module 100 includes at least one AC-DC conversion unit 110, and the AC-DC conversion unit 110 is electrically connected with the corresponding switching module 300. The AC-DC conversion unit 110 serves to convert the 220V alternating current into direct current.

The DC-DC conversion unit 120 serves to convert the direct current output from the AC-DC conversion unit 110 into a suitable charging voltage and supply the same to a corresponding battery. It should be noted that the ellipses in fig. 1 represent the repeated meanings of the modules or units.

In particular, in some embodiments of the present invention, each AC-DC conversion unit 110 is electrically connected to a plurality of DC-DC conversion units 120. The power of the AC-DC conversion unit 110 is much larger than that of the DC-DC conversion unit 120, and the normal use of the DC-DC conversion unit 120 can be satisfied without using complicated logic to distribute the power of each DC-DC conversion unit 120. In addition, 1 AC-DC conversion unit 110 drives a plurality of DC-DC conversion units 120, which may also reduce the number of AC-DC conversion units 110 and increase the number of interfaces 400. It can be understood that, the number of the AC-DC conversion units 110 is set to be n, and each AC-DC conversion unit 110 drives m switching modules 300, so that the number of the switching modules 300 is m × n. With regard to the setting of the size m, the embodiment of the present invention is not particularly limited, and may be selected according to the requirement.

In particular, in some embodiments of the present invention, each DC-DC conversion unit 120 is electrically connected to one switching module 300. Considering that the DC-DC conversion unit 120 has the characteristic of small power, 1 DC-DC conversion unit 120 drives only one switching module 300, and it is not necessary to adopt complicated logic to distribute the power of each switching module 300.
