Description

Technical Field

[0001] This utility model relates to the field of shared battery swapping cabinets, and in particular to an intelligent shared battery swapping cabinet. Background Technology

[0002] A battery swapping cabinet is a cabinet that can store electric vehicle batteries and automatically charge them. It looks similar to a locker and has many compartments, each of which can store one electric vehicle battery. Currently, electric vehicles generally use batteries for power. Once the electric vehicle battery is depleted, it needs to be charged in time. This can be done quickly by swapping the battery in the battery swapping cabinet.

[0003] The shared power supply and battery swapping cabinet needs to ensure the stability of IoT communication and the continuous operation of the low-voltage system (control motherboard, sensors, etc.). In the existing technology, single-card communication is prone to service interruption due to signal interruption, and the low-voltage system will directly lose power after the mains power is disconnected, causing the equipment to go out of control. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent shared battery swapping cabinet that solves the problems of communication redundancy and continuous power supply for weak current through dual-card automatic switching and reverse battery power supply mechanism, thereby improving system robustness and solving the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] A smart shared battery swapping cabinet includes a smart charging cabinet with several charging compartments distributed within it. Each charging compartment has a charging connection module installed inside its cavity. The top cover of the smart charging cabinet contains a main control board module, a battery reverse power supply module, and a low-voltage protection module. The battery reverse power supply module includes a reverse connection protection circuit unit and a DC-DC conversion unit. After the mains power is disconnected, the battery pack outputs low voltage to the main control board module of the battery swapping cabinet through the battery reverse power supply module for power supply. The low-voltage protection module monitors the battery level in real time during battery power supply and triggers a low-voltage alarm. The smart charging cabinet also includes a heat dissipation component for rapid heat dissipation during battery charging and power supply.

[0007] Preferably, the heat dissipation component includes a heat dissipation part provided on the right end face of the smart charging cabinet, a heat dissipation cavity provided in the heat dissipation part, a heat dissipation fan fixedly installed in the heat dissipation cavity, a heat dissipation channel provided in the smart charging cabinet, the bottom of each charging compartment being interconnected with the heat dissipation channel, and a fan mesh being installed at the connection point, and the heat dissipation channel being interconnected with the heat dissipation cavity.

[0008] Preferably, the bottom of the charging compartment is equipped with anti-scratch strips on the left and right sides of the air mesh.

[0009] Preferably, the main control board module integrates two IoT cards and adopts a heterogeneous operator design. Each IoT card is equipped with an independent communication unit. When the communication of one IoT card fails, it automatically switches to the other IoT card for communication.

[0010] Preferably, a partition window is installed on the outer surface of the heat dissipation part, and strip-shaped ventilation holes are evenly distributed in the partition window.

[0011] Preferably, the charging compartment opening is equipped with an electrically controlled door.

[0012] The advantages and positive effects of this utility model are:

[0013] This utility model uses a dual-card automatic switching and battery reverse power supply mechanism. When the mains power is normal, the battery reverse power supply module maintains a fully charged backup power supply. After the mains power is interrupted, the reverse connection protection circuit and DC-DC conversion module (efficiency ≥93%) seamlessly switch to battery power supply to ensure that the main control board, electric control door and other core components continue to operate for at least 4 hours, and the user's battery swapping process is not disturbed.

[0014] The dual IoT SIM (heterogeneous operator) design, combined with parallel signal monitoring algorithms, reduces communication link switching time to less than 150ms (traditional solutions ≥500ms), reduces packet loss rate by 82%, ensures 24 / 7 remote control stability, and supports remote dynamic adjustment of switching thresholds (such as signal strength and data plan optimization), thereby reducing operation and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0027] Please see Figure 1-5This utility model provides an embodiment of an intelligent shared battery swapping cabinet, comprising an intelligent charging cabinet 10. The intelligent charging cabinet 10 has several charging compartments 11 distributed within it. Each charging compartment 11 has a charging connection module 12 installed in its inner cavity for charging the battery pack. A main control board module 19, a battery reverse power supply module 20, and a low-voltage protection module 21 are respectively installed in the inner cavity of the top cover of the intelligent charging cabinet. These three modules work together to control the charging of the cabinet.

[0028] The main control board module 19 integrates dual SIM cards (supporting 4G / 5G) (dual patch cards, one patch card slot per SIM card slot, dual SIM card slots, etc.). The dual IoT cards adopt a heterogeneous operator design. The primary card and the backup card have independent communication modules that support parallel signal monitoring. When the primary card communication is abnormal (signal strength < -90dBm or packet loss rate > 5%), the control chip switches to the backup card within 150ms in the heat dissipation channel. There is no data loss during the switching process. The communication module has a built-in self-test program and supports remote configuration of switching thresholds and priorities (such as data plan optimization).

[0029] The battery reverse power supply module 20 includes a reverse connection protection circuit unit and a DC-DC conversion unit. When the mains power is normal, the lithium battery pack is kept fully charged through the charging circuit. After the mains power is disconnected, the battery pack outputs a 12V low voltage from the charging connection module to the main control board module 19 through the reverse connection protection circuit and the DC-DC conversion module. At the same time, priority control logic is adopted: after the mains power is disconnected, the battery reverse power supply is automatically activated, and an anti-reverse current diode is set at the output terminal to prevent current backflow.

[0030] The low-voltage protection module 21 monitors the battery power in real time during battery power supply and triggers a low power alarm (threshold ≤ 20% of battery reverse power supply module);

[0031] During battery charging, the heat in the charging compartment 11 needs to be dissipated in a timely manner. Therefore, the intelligent charging cabinet 10 is also equipped with a heat dissipation component for rapid heat dissipation during battery charging and power supply.

[0032] In another embodiment, the heat dissipation assembly includes a heat dissipation section 22 disposed on the right end face of the intelligent charging cabinet 10. The heat dissipation section 22 contains a heat dissipation chamber 16, and a heat dissipation fan 17 is fixedly installed in the heat dissipation chamber 16. The intelligent charging cabinet 10 contains a heat dissipation channel 15. The bottom of each charging compartment 11 is interconnected with the heat dissipation channel 15, and a ventilation net 14 is installed at the connection point. The heat dissipation channel 15 is interconnected with the heat dissipation chamber 16. Anti-scratch strips 13 are installed on the left and right sides of the ventilation net 14 at the bottom of each charging compartment 11. A partition window 18 is installed on the outer surface of the heat dissipation part 22. The partition window 18 is provided with strip-shaped ventilation holes evenly distributed. When the battery pack is being charged, it slides into the charging compartment 11 along the anti-scratch sliding strip 13 and connects the battery charging port to the charging connection module 12 for charging. At this time, the battery pack is located on the upper side of the air mesh 14. At this time, the heat exhaust fan 17 is activated to absorb heat, so that the heat in each charging compartment 11 is absorbed and discharged by the heat exhaust fan 17 along the heat dissipation channel 15, thereby ensuring that each charging compartment 11 does not overheat, and thus protecting the battery pack.

[0033] In another embodiment, an electrically controlled door 23 is installed at the opening of the charging compartment 11.

[0034] In practice, the battery is inserted into the empty charging compartment 11 and slid into the compartment along the anti-scratch strip 13. The charging connection module 12 connects to the battery's charging port, and the main control board module 19 starts the charging program. The temperature inside the charging compartment 11 rises to 42°C due to fast charging. The heat dissipation fan 17 starts the strong wind mode (speed 2500rpm) through the heat dissipation channel 15. The air mesh 14 guides the hot airflow through the heat dissipation cavity 16 and exhausts it through the strip-shaped holes of the partition window 18. Within 5 minutes, the compartment temperature drops to 32°C. The main control board module 19 detects that the signal strength of the main card (China Mobile) drops sharply to -95dBm (due to the failure of the surrounding base station). The self-test program triggers parallel monitoring. After confirming that the packet loss rate reaches 8%, the control chip switches to the backup card (China Telecom IoT card) within 122ms. The switching process caches data through an independent communication module, so the user terminal App is unaware of it, and the process of rider B scanning the code to obtain a fully charged battery is not affected.

[0035] In the event of a sudden power outage, the battery reverse power supply module 20 is immediately activated.

[0036] The reverse connection protection circuit unit blocks reverse current flow, and the DC-DC conversion unit steps down the 48V lithium battery pack to a low-voltage 12V. Priority is given to powering the main control board module 19, the electric control door 23, and the communication module, while the cabinet operation panel switches to power-saving mode. The low-voltage protection module 21 monitors the reverse-powered battery level in real time, and when the level drops to 22% (threshold 20%), it sends a low-battery warning to the maintenance platform.

[0037] Mains power will be restored in 30 minutes, and the system will execute automatically:

[0038] The main control board 19 switches back to AC power supply, and the battery reverse power supply module 20 enters the float charging state; the heat dissipation component starts the self-cleaning program, and the heat dissipation fan 17 blows the dust accumulated in the heat dissipation channel 15 in the reverse direction; the maintenance personnel remotely receive the status report and synchronously update the main and backup card switching threshold to the signal strength -85dBm.

[0039] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
