Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
Fig. 1 is a schematic structural diagram of a charging cabinet according to an embodiment of the present application. Referring to fig. 1, the charging cabinet includes: a first number of charging modules 100 and a second number of charging bays 200 for receiving rechargeable batteries;
each charging module 100 includes:
an energy storage device 110 for charging the charging battery in the connected charging bin 200;
and a charging switching module 120 connected between the energy storage device 110 and the charging bin 200, for switching the connection relationship between the energy storage device 110 and the charging bin 200, wherein the same energy storage device 110 can be connected with at most one charging bin 200 at the same time.
Specifically, the charging cabinet is a power change cabinet or a power rental cabinet and is used for charging rechargeable batteries of electric bicycles and other equipment. The first number of the charging modules 100 and the second number of the charging bins 200 may be equal or different.
The energy storage device 110 is a chargeable and dischargeable energy storage and supply device. The energy storage device 110 is used for storing electric energy during charging and charging the battery to be charged during discharging. The energy storage device 110 may be specifically a charger.
The charging bin 200 is a cabin or a box of the charging cabinet, and is used for accommodating the rechargeable battery and receiving the electric energy provided by the energy storage device 110 connected with the rechargeable battery to charge the rechargeable battery.
Each charging module 100 includes an energy storage device 110 and a charging switching module 120 corresponding to each other. The energy storage device 110 can be connected to different charging bays 200 through the charging switching module 120. The charging switching module 120 is used for controlling the connection relationship between the energy storage device 110 and the charging bin 200 in the same charging module 100. Through the switching function of the charging switching module 120, one energy storage device 110 can be connected with different charging bins 200, but one energy storage device 110 can be connected with only one charging bin 200 at the same time and charges the rechargeable batteries accommodated in the connected charging bins 200.
The charging bays 200 to which different energy storage devices 110 may be connected may be partially identical, for example, a first energy storage device 110 may be connected to the 1 st and 2 nd charging bays 200, a second energy storage device 110 may be connected to the 2 nd and 3 rd charging bays 200, a third energy storage device 110 may be connected to the 1 st and 3 rd charging bays 200, and so on, without being limited thereto. Charging bays 200 to which different energy storage devices 110 can be connected may also be identical, i.e., each energy storage device 110 may be connected to any one of charging bays 200. For example, first energy storage device 110, second energy storage device 110, and third energy storage device 110 may each be coupled to the 1 st, 2 nd, and 3 rd charging bays 200.
In this embodiment, the energy storage device 110 can be switched to connect different charging bins 200 through the charging switching module 120, so as to charge different charging bins 200, thereby breaking the one-to-one single relationship between the energy storage device 110 and the charging bins 200 in the prior art, realizing the one-to-many relationship between the energy storage device 110 and the charging bins 200, and solving the problem that the energy storage device 110 is damaged in the one-to-one configuration relationship and cannot charge the battery in the charging bin 200, so that the configuration between the energy storage device 110 and the charging bin 200 is more flexible and various, after a certain energy storage device 110 is damaged, other energy storage devices 110 can be flexibly called to charge the battery, a plurality of backup switchable energy storage devices 110 are configured for each charging bin 200, thereby effectively ensuring the normal operation of the charging function of the charging cabinet, and saving the energy storage device 110.
In one embodiment, the same charging bin 200 may be connected to at least one energy storage device 110 at a time.
Specifically, under the condition that the circuit has no abnormality, the same energy storage device 110 can only be connected with one charging bin 200 at the same time, but at least one energy storage device 110 can be connected with the same charging bin 200 at the same time to charge the rechargeable batteries in the same charging bin 200. At this time, the charging current of the rechargeable battery is the sum of the charging currents of the energy storage devices 110 connected in parallel. For example, at the same time, the first energy storage device 110, the second energy storage device 110, and the third energy storage device 110 are all connected to the 1 st charging bin 200 to charge the rechargeable battery in the 1 st charging bin 200, and at this time, the charging current of the rechargeable battery in the 1 st charging bin 200 is the sum of the charging currents provided by the first energy storage device 110, the second energy storage device 110, and the third energy storage device 110.
Of course, the first energy storage device 110, the second energy storage device 110, and the third energy storage device 110 may also be separately connected to the 1 st charging bin 200, respectively, to separately charge the rechargeable batteries in the 1 st charging bin 200. Any 2 of the first energy storage device 110, the second energy storage device 110 and the third energy storage device 110 can also be selected to be connected with the 1 st charging bin 200, so as to charge the rechargeable batteries in the 1 st charging bin 200 at the same time. The more energy storage devices 110 that are charged simultaneously, the faster the rechargeable battery charges.
The charging compartments 200 to which each energy storage device 110 can be connected, and the energy storage devices 110 to which each charging compartment 200 can be connected at most at the same time can be configured according to practical application scenarios, which is not limited in this application.
Preferably, the charging switching module 120 can switch the energy storage device 110 of the same charging module 100 to be connected with any one charging bin 200 of the second number of charging bins 200. Thus, each energy storage device 110 can be used as a backup power supply device for different charging bins 200, so that charging is spare and free, and more options are available.
In the embodiment, the same charging bin 200 is configured to be connected with at least one energy storage device 110, so that various different choices of high-power quick charging and low-power slow charging of the battery are realized, charging modes with different charging speeds can be flexibly realized, and various different requirements are met.
In one embodiment, the charge switching module 120 includes at least one relay, each relay including a common contact, a normally closed contact, and a normally open contact;
if the charging switching module 120 includes a relay, a common contact of the relay is connected to the energy storage device 110 of the same charging module 100, a normally closed contact is connected to one charging bin 200, and a normally open contact is connected to another charging bin 200, and the common contact can be controlled to be connected to the normally closed contact or the normally open contact, so as to switch the connection relationship between the corresponding energy storage device 110 and the charging bin 200;
if the charging switching module 120 includes at least two relays, the common contact of the first relay is connected to the energy storage device 110 of the same charging module 100, the previous relay is connected to the common contact of the next relay through the normally closed contact of the previous relay, the normally closed contact of the last relay is connected to a charging bin 200, the normally open contact of each relay is connected to a charging bin 200, the common contact of the same relay can be controlled to be connected to the normally closed contact or to the normally open contact, so as to switch the connection relationship between the corresponding energy storage device 110 and the charging bin 200, wherein the charging bins 200 connected to the normally closed contact and the normally open contact are different.
Specifically, the number of relays determines how many different charging bays 200 one energy storage device 110 can be switched to connect. The number of relays included in each charge switching module 120 may or may not be equal. For example, if the first charging switching module 120 includes 1 relay, its corresponding energy storage device 110 may be connected to 2 different charging bays 200; the second charging switching module 120 includes 2 relays, and its corresponding energy storage device 110 can be connected to 3 different charging bays 200; the third charging switching module 120 includes 3 relays, and the corresponding energy storage device 110 can be connected to 4 different charging bays 200, and so on.

The common contact 31 is also controlled to connect with the normally closed contact 32 or with the normally open contact 33.
And so on:
the common contact of the relay RL4 is connected with the energy storage device 2, the normally closed contact is connected with the common contact of the relay RL5, and the normally open contact is connected with the charging bin 1.

The common contact of the relay RL6 is also controlled to be connected with its normally closed contact or with its normally open contact.
The common contact of the relay RL7 is connected with the energy storage device 3, the normally closed contact is connected with the common contact of the relay RL8, and the normally open contact is connected with the charging bin 1. The common contact of the relay RL7 is also controlled to be connected with its normally closed contact or with its normally open contact.
The common contact of the relay RL8 is connected with the normally closed contact of the relay RL7, the normally closed contact is connected with the common contact of the relay RL9, and the normally open contact is connected with the charging bin 2.

The anode of the energy storage device 110 is connected to the common contact of the first electronic relay, and the cathode of the rechargeable battery in the charging bin 200 is connected to the cathode of the energy storage device 110 connected to the charging bin 200 through the terminal row.
Fig. 2 is only a specific exemplary example of the present application, the number of relays included in each charging switching module 120 in the charging cabinet of the present application may be equal or different, and the charging cabinet to which the normally open contact or the normally closed contact of each relay is connected may be configured in a customized manner according to an actual application scenario, which is not limited in the present application.
Preferably, the number of relays included in each charging switching module 120 is a third number, the third number is smaller than the second number, and the difference is 1. In this way, it is ensured that each energy storage device 110 can be connected to any one charging bin 200 of the second number of charging bins 200. Each charging bin 200 is ensured to be configured with the maximum number of standby energy storage devices 110, so that the charging battery of each charging bin 200 can be normally charged, and the possibility of charging delay is reduced.
In the embodiment, the connection relationship between the energy storage device 110 and the charging bins 200 is flexibly switched by using the characteristics of the normally closed contact and the normally open contact of the electronic relay, so that each charging bin 200 is ensured to have a plurality of standby energy storage devices 110, and the batteries in the charging bins 200 can be normally charged; in addition, the public contact is connected with the normally closed contact or the normally open contact, and the uniqueness of the connection of the relay can not lead to the parallel connection of the two groups of batteries even when the electronic relay is abnormally adhered, so that the safety of the switching circuit and the whole charging cabinet is improved.
In one embodiment, in a default state, the common contact of the same relay is connected with the normally closed contact.
Specifically, in a default state, the common contact of each relay is connected to the normally closed contact thereof, and then the corresponding energy storage device 110 is connected to one charging bin 200 sequentially through the common contact and the normally closed contact of all the relays. Thus, by default, the energy storage device 110 is connected to the charging chamber 200 and charges the battery of the charging chamber 200.
Specifically, as shown in fig. 2, in the default state, the energy storage device 1 is connected to the charging bin 1 sequentially through the common contact 11 of the relay RL1, the normally closed contact 12, the common contact 21 of the relay RL2, the normally closed contact 22, the common contact 31 of the relay RL3, and the normally closed contact 32. Therefore, in the default state, the energy storage device 1 charges the rechargeable battery in the charging bin 1.
Similarly, in a default state, the energy storage device 2 is connected with the charging bin 2 sequentially through the common contact and the normally closed contact of the relay RL4, the common contact and the normally closed contact of the relay RL5 and the common contact and the normally closed contact of the relay RL 6. Thus, in the default state, the energy storage device 2 charges the rechargeable battery in the charging bin 2.
In a default state, the energy storage device 3 is connected with the charging bin 3 sequentially through the common contact and the normally closed contact of the relay RL7, the common contact and the normally closed contact of the relay RL8, and the common contact and the normally closed contact of the relay RL9. Thus, in the default state, the energy storage device 3 charges the rechargeable battery in the charging bin 3.
Certainly, under the default state, same storehouse of charging can be connected with a plurality of different energy memory, and the storehouse of should charging can realize acquiescent quick charge function under the default state like this.
Fig. 2 is an exemplary example, and a fourth charging module 100 (not shown) may be added to fig. 2, where the fourth charging module 100 includes the energy storage device 4, the relays RL10, RL11, and RL12. The connection of energy storage device 4, relays RL10, RL11, and RL12 is as shown above for the first charging module 100 through the third charging module 100. Under a default state, the energy storage device 4 is connected with the charging bin 4 sequentially through the common contact and the normally closed contact of the relay RL10, the common contact and the normally closed contact of the relay RL11 and the common contact and the normally closed contact of the relay RL12. Thus, in the default state, the energy storage device 4 charges the rechargeable battery in the charging bin 4. Therefore, each charging bin 200 can be provided with the connected energy storage device 110 at the same time, and the charging function of the charging cabinet is met.
In addition, a fifth charging module 100 (not shown) may be added to fig. 2, where the fifth charging module 100 includes the energy storage device 5, and relays RL13, RL14, and RL15. The connection of energy storage device 5, relays RL13, RL14, and RL15 is as shown above for the first charging module 100 through the fourth charging module 100. In a default state, the energy storage device 5 is connected with any one of the charging bin 1-the charging bin 4 through a common contact and a normally closed contact of the relay RL13, a common contact and a normally closed contact of the relay RL14, and a common contact and a normally closed contact of the relay RL15 in sequence. Therefore, in the default state, the energy storage device 5 charges the rechargeable battery in any one of the charging bays 200 of the charging bay 1-the charging bay 4.
For example, in the default state, the energy storage device 5 is connected to the charging bin 1, so that the energy storage device 1 and the energy storage device 5 are both connected to the charging bin 1 in the default state, and the charging speed of the charging bin 1 in the default state is faster than that of the other charging bins 200. Therefore, the charging bin 200 with different charging speeds can be configured for the charging cabinet, and different charging requirements are met.
In the embodiment, the normally closed contacts of the electronic relay are fully utilized to connect a group of batteries as a default state to charge the batteries, and when other batteries need to be charged, the normally closed contacts of the other electronic relays can be correspondingly disconnected or closed so as to disconnect the loop of default connection and switch to other loops to charge other charging bins 200.
By ensuring that the energy storage device 110 is connected with one charging bin 200 in a default state, the connection relationship does not need to be switched, and quick charging can be realized. Under the actual charging requirement, the default state can be broken through, the connection relation between the energy storage device 110 and the charging bin 200 is switched, a plurality of energy storage devices 110 are connected with one charging bin 200, the charging bin 200 with higher charging speed is configured, and the quick charging function of the charging cabinet is realized.
