Description

Technical Field

[0001] This invention relates to a management system for swappable batteries, and more particularly to a portable battery management system for use in energy cabinets. Background Technology

[0002] Modern electric vehicles all use portable battery systems, which can be recharged when their power is low. However, because portable batteries in electric vehicles have a large energy storage capacity, they require a relatively long charging time and cannot generally be fully charged quickly.

[0003] To address this situation, a battery swapping system has been developed. This system involves setting up battery swapping stations at fixed locations, each equipped with multiple battery storage slots to hold portable batteries from electric vehicles and to charge them. Users can exchange their depleted portable batteries for fully charged ones at the swapping station, thus quickly replenishing their electric vehicle's power and extending its range.

[0004] Battery swapping stations typically include a diagnostic module to diagnose whether portable batteries are malfunctioning. When a battery swapping station detects that a portable battery is malfunctioning, it will lock the malfunctioning portable battery to prevent the user from swapping in a malfunctioning portable battery.

[0005] When a faulty portable battery is locked, it occupies a battery compartment, which affects the battery exchange station's utilization rate of portable batteries and reduces the overall exchange rate. Summary of the Invention

[0006] [The technical problem the invention aims to solve]

[0007] Given that existing battery swapping stations lock up abnormal portable batteries when they are diagnosed, which affects the utilization rate of portable batteries in the operation of the battery swapping station and reduces the swapping rate of portable batteries, this invention proposes a portable battery management system for energy cabinets to address this problem.

[0008] [Technical means to solve the problem]

[0009] According to a technical means of the present invention, the portable battery management system of the energy cabinet of the present invention comprises:

[0010] One energy cabinet, comprising:

[0011] Multiple battery compartments for accommodating portable batteries;

[0012] One battery communication unit;

[0013] One charging unit;

[0014] One cloud communication unit;

[0015] A control unit is electrically connected to the charging unit, the battery communication unit, and the cloud communication unit; wherein, when the control unit receives a portable battery being placed in one of the battery receiving slots, the control unit receives battery information transmitted by the portable battery through the battery communication unit, generates association information based on the battery information, and sends the association information through the cloud communication unit.

[0016] A cloud server is connected to the energy cabinet. The cloud server determines whether the portable battery is abnormal based on the battery information in the associated information.

[0017] When the cloud server determines that the portable battery is abnormal, the cloud server sends an unlock command to the energy cabinet to unlock the abnormal portable battery.

[0018] Preferably, when the cloud server schedules the unlocking time, the cloud server determines the geographical location of the energy cabinet based on the energy cabinet serial number information in the associated information, and schedules the unlocking time based on the geographical location. Furthermore, after the cloud server schedules the unlocking time, it further schedules an abnormal battery maintenance sequence based on the unlocking time.

[0019] Preferably, the portable battery management system of the energy cabinet further includes an electronic device. This electronic device is communicatively connected to the cloud server. When the cloud server schedules the maintenance of the abnormal battery, it sends abnormal battery maintenance sequence information to the electronic device, which then displays this information.

[0020] [Effects of the invention]

[0021] When the cloud server determines that a portable battery in the energy cabinet is abnormal, the cloud server will send an unlock command to the energy cabinet to unlock the abnormal portable battery, thereby improving the utilization rate of the portable battery and the exchange rate of the portable battery in the energy cabinet.

[0022] Furthermore, the cloud server automatically sends the unlock command, allowing maintenance personnel to quickly and efficiently travel to the energy cabinet site to replace or repair the malfunctioning portable battery. Upon arrival, the malfunctioning battery is automatically unlocked, allowing maintenance personnel to directly remove it, thus improving operational efficiency. Moreover, the cloud server's scheduled maintenance sequence for the malfunctioning battery further enhances operational efficiency, and this sequence information can be displayed on an electronic device, making it easier for maintenance personnel to view and monitor maintenance information at any time.

[0055] refer to Figure 1 As shown, the portable battery management system for the energy cabinet provided by the present invention includes an energy cabinet 10 and a cloud server 20. The energy cabinet 10 is connected to the cloud server 20 via an Internet 40.

[0056] Please refer to Figure 2 , Figure 3A and Figure 3B As shown, the energy cabinet 10 includes multiple battery storage slots 11, a battery communication unit 12, a charging unit 13, a control unit 14, and a cloud communication unit 15. The control unit 14 is electrically connected to the battery communication unit 12, the charging unit 13, and the cloud communication unit 15. The battery storage slots 11 are for accommodating multiple portable batteries 30, enabling the control unit 14 to control the charging unit 13 to charge the portable batteries 30.

[0057] When the control unit 14 receives a new portable battery 20 inserted into one of the battery receiving slots 11, the control unit 14 receives battery information provided by the portable battery 30 through the battery communication unit 12, generates association information based on the battery information, and sends the association information through the cloud communication unit 15. The details of the battery information and the association information will be explained in more detail later.

[0058] The cloud server 20 is communicatively connected to the cloud communication unit 15 of the energy cabinet 10. When the cloud server 20 receives the associated information, it can determine whether the portable battery 30 is abnormal based on the associated information.

[0059] If the cloud server 20 determines that the portable battery 30 is abnormal, the cloud server 20 sends an unlock command to the energy cabinet 10.

[0060] Furthermore, when the control unit 14 of the energy cabinet 10 receives the unlocking command sent by the cloud server 20 through the cloud communication unit 15, the control unit 14 automatically unlocks the abnormal portable battery 10.

[0061] In this embodiment, the battery communication unit 12 may be a controller area network (CAN) unit or a near-field communication (NFC) unit, and the cloud communication unit 15 may be a fourth-generation (4G) mobile communication unit or a fifth-generation (5G) mobile communication unit.

[0062] Each portable battery 30 includes a Battery Management System (BMS) 301 and a battery pack 302. The Battery Management System 301 includes a control circuit 31, a communication module 32, a temperature sensing module 33, a voltage sensing module 34, and a current sensing module 35. The control circuit 31 includes a processing module 311, a charge / discharge switch 312, a fuse 313, and a storage module 314.

[0063] The battery cell assembly 302 includes multiple rechargeable battery cells, each of which can be a lithium battery. The multiple battery cells in the battery cell assembly 302 can be interconnected in series, parallel, or a combination of series and parallel to output a battery voltage, for example, providing a battery voltage below 60V.

[0064] The processing module 311 of the control circuit 31 is electrically connected to the communication module 32, the temperature sensing module 33, the voltage sensing module 34 and the current sensing module 35, and the processing module 311 is further electrically connected to the charge / discharge switch 312 and the storage module 314, and the storage module 314 stores the battery information.

[0065] Furthermore, the charge / discharge switch 312 is further connected to the battery cell assembly 302. When the portable battery 30 is placed into the battery housing slot 11 of the energy cabinet 10, the charge / discharge switch 312 and the communication module 32 of the portable battery 30 are respectively connected to the charging unit 13 and the battery communication unit 12 of the energy cabinet 10. When the portable battery 30 is placed into the energy cabinet 10, the control unit 14 of the energy cabinet 10 receives the battery information through the battery communication unit 12 and uploads the battery information to the cloud server 20 through the cloud communication unit 15. The cloud server 20 then verifies whether the battery identification code information of the portable battery 30 matches. When the cloud server 20 determines that the battery identification code information matches, the cloud server 20 sends a verification pass message to the energy cabinet 10, so that the energy cabinet 10 locks the portable battery 30 by a locking mechanism 111 of the battery receiving slot 11 and charges the portable battery 30.

[0066] The portable battery 30 has a fuse 313 installed in the control circuit 31 to protect the internal circuitry of the portable battery 30. For example, the fuse 313 can be located between the charge / discharge switch 312 and the battery cell assembly 302. In this embodiment, the processing module 311 is a microcontroller unit (MCU), and the charge / discharge switch 312 is a metal-oxide-semiconductor field-effect transistor (MOSFET).

[0067] The temperature sensing module 33, the voltage sensing module 34, and the current sensing module 35 are electrically connected to the battery cell module 302, respectively, for sensing the temperature, voltage, and current of the battery cell module 302 when it is charging in the energy cabinet 10, and generating temperature information, voltage information, and current information respectively. When the control circuit 31 receives the temperature information, voltage information, and current information, the processing module 311 further determines whether the battery cell module 302 is abnormal based on the temperature information, voltage information, and current information. When the battery cell module 302 is determined to be abnormal, the processing module 311 generates an abnormality information and stores the abnormality information in the storage module 314. For example, the abnormal status information may include information such as a portable battery overheating, a portable battery underheating, a portable battery undervoltage, a portable battery low health, a portable battery temperature sensing module malfunction, a portable battery charge / discharge switch malfunction, or a portable battery fuse blown. For instance, when the processing module 311 determines that the portable battery 30 is overheating while charging in the power cabinet 10 based on the temperature information, the control circuit 31 generates the portable battery overheating information. The portable battery health is calculated based on the internal resistance of the battery using the voltage and current information, thereby estimating the health of the battery cell assembly 302 and determining the overall battery health. In addition, the processing module 311 will determine whether the charge / discharge switch 312 and the fuse 313 are abnormal. When the charge / discharge switch 312 cannot be started or the fuse 313 is blown, it means that the charge / discharge switch 312 or the fuse 313 is abnormal, and the processing module 311 will also generate abnormal status information.

[0068] Furthermore, the processing module 311 is communicatively connected to the battery communication unit 12 of the energy cabinet 10 via the communication module 32 to form a communication loop. In this way, the processing module 311 can send battery information to the control unit 14 of the energy cabinet 10 through the communication loop. The battery information includes abnormal condition information and battery identification code information. Therefore, when the control unit 14 receives the battery information, it generates associated information based on the abnormal condition information and the battery identification code information.

[0069] The associated information includes battery information, a power cabinet serial number, and a battery compartment number. The power cabinet 10 itself has a power cabinet serial number, and each battery compartment 11 of the power cabinet 10 has a battery compartment number. Therefore, when the portable battery 30 is placed into one of the battery compartments 11, the control unit 14 can determine which battery compartment 11 has been used to insert the portable battery 30 based on the battery compartment number. The control unit 14 further combines the power cabinet serial number, the battery compartment number of the battery compartment 11 into which the portable battery 30 is placed, and the battery information received from the portable battery 30 to generate the associated information, and sends the associated information to the cloud server 20 for the cloud server 20 to determine if the portable battery is abnormal.

[0070] In a first embodiment of the present invention, when the cloud server 20 determines that the portable battery 30 placed in the battery receiving slot 11 is abnormal, the cloud server 20 schedules an unlocking time, and only when the unlocking time arrives will it send the unlocking command to the energy cabinet 10, so that the energy cabinet 10 unlocks the abnormal portable battery 30.

[0071] In a second embodiment of the present invention, when the cloud server 20 determines that the portable battery 30 placed in the battery housing 11 is abnormal, the cloud server 20 sends an unlock command to the energy cabinet 10, and the unlock command includes the unlock time scheduled by the cloud server 20. When the control unit 14 of the energy cabinet 10 receives the unlock command through the cloud communication unit 15, the control unit 14 starts timing, and the control unit 14 unlocks the abnormal portable battery 30 when the unlock time in the unlock command is reached.

[0072] Therefore, maintenance personnel can quickly and efficiently travel to the site of the energy cabinet 10 to replace or repair any unlocked, faulty portable batteries. Furthermore, by the time maintenance personnel arrive, the faulty portable batteries have already automatically unlocked, allowing for immediate removal, thereby improving the operational efficiency of the maintenance personnel.

[0073] Furthermore, upon receiving the association information, the cloud server 20 can also identify the battery identification code information of the portable battery 30 inserted into the energy cabinet 10 based on the battery information in the association information. When the battery identification code information is incorrect or cannot be verified, the cloud server 20 sends a control command to the energy cabinet 10 to remove the portable battery 30 from the energy cabinet 10.

[0074] Please see Figure 4As shown, the portable battery management system of the energy cabinet also includes an electronic device 50, which is connected to the cloud server 20 via the Internet 40. Regarding how the unlocking time should be scheduled, in a preferred embodiment, the cloud server 20 determines the geographical location of the energy cabinet 10 based on the energy cabinet serial number information and schedules the unlocking time accordingly. In the first embodiment, after the cloud server 20 schedules the unlocking time, it further schedules an abnormal battery maintenance sequence based on the unlocking time. In the second embodiment, the abnormal battery maintenance sequence is still scheduled by the cloud server 20 based on the unlocking time. After scheduling the abnormal battery maintenance sequence, the cloud server 20 sends abnormal battery maintenance sequence information to the electronic device 50, which then displays the abnormal battery maintenance sequence information. For example, the electronic device 50 series is the screen of a smart device, a tablet computer, a personal computer, or a laptop computer, used to display the abnormal battery maintenance sequence information.

[0075] For example, when an abnormal portable battery appears in energy cabinet 10, the cloud server 20 begins scheduling maintenance tasks, notifying personnel at the maintenance center to retrieve the abnormal portable battery from the location of energy cabinet 10. Therefore, the closer the location of energy cabinet 10 is to the location of the maintenance center, the shorter the scheduled unlocking time, and vice versa. For instance, for energy cabinet 10 located within 10 kilometers of the maintenance center, the scheduled unlocking time is 12 hours, while for energy cabinet 10 located more than 10 kilometers but within 20 kilometers, the scheduled unlocking time is 18 hours. Furthermore, when arranging the maintenance sequence of the abnormal batteries, the cloud server 20 can schedule them according to the remaining unlocking time. For example, if one of the abnormal portable batteries 30 in one energy cabinet 10 has only 6 hours left to unlock, while the other abnormal portable battery 30 in another energy cabinet 10 has 10 hours left to unlock, then the scheduled maintenance sequence requires maintenance personnel to first reach the abnormal portable battery with only 6 hours left to unlock, and then proceed to the abnormal battery with 10 hours left to unlock.

[0076] In other words, the cloud server 20 can determine the geographical location of the energy cabinet 10 and which battery compartment 11 of which energy cabinet 10 the portable battery 30 is placed in, based on the energy cabinet serial number and battery compartment number information in the associated information. This provides maintenance personnel with more accurate information, thereby improving operational efficiency. Furthermore, maintenance personnel can use the electronic device 50 to confirm the maintenance sequence information for abnormal batteries and arrange the maintenance sequence for abnormal portable batteries accordingly, thereby improving the efficiency of replacing or repairing abnormal portable batteries.

[0077] In another embodiment, the electronic device 50 is a mobile device 51, such as a smartphone, which can be carried by maintenance personnel. The mobile device 51 has an application (APP) installed on it for exchanging information with the cloud server. When maintenance personnel arrive at the energy cabinet 10 before the unlocking time, they can connect to the cloud server 20 via the application on the mobile device 51 and generate an early unlocking message, which is then sent to the cloud server 20. When the cloud server 20 receives the early unlocking message, it generates and sends an unlocking command to the energy cabinet 10 based on the message. The early unlocking message includes a battery identification code, an energy cabinet serial number, and a battery compartment number for the corresponding abnormal portable battery 30.

[0078] Furthermore, the unlock command includes a battery identification code, a power cabinet serial number, and a battery compartment number corresponding to the abnormal portable battery 30. In this second embodiment, the unlock command further includes the unlock time.

[0079] Furthermore, when maintenance personnel arrive at the location of the energy cabinet 10 before the unlocking time, they can manually unlock the energy cabinet 10 to remove the faulty portable battery 30. Since the energy cabinet 10 has a sensor switch to detect whether the battery compartment 11 of the energy cabinet 10 has been unlocked, when maintenance personnel manually unlock the battery compartment 11 of the energy cabinet 10, the control unit 14 receives a notification that the battery compartment 11 containing the faulty portable battery 30 has been unlocked. The control unit 14 generates a manual early unlocking message and sends this message to the cloud server 20 via the cloud communication unit 15, notifying the cloud server 20 that the maintenance personnel have arrived on site and removed the faulty portable battery 30. The manual early unlocking message includes a battery identification code, an energy cabinet serial number, and a battery compartment number corresponding to the faulty portable battery 30.

[0080] In this way, even if the maintenance personnel arrive at the location of the power cabinet 10 before the unlocking time, they can still unlock the battery compartment 11 by operating the application of the mobile device 51 or by using a physical key to remove the abnormal portable battery 30.

[0081] Furthermore, please refer to Figure 5As shown, the energy cabinet 10 further includes a recording unit 16 and multiple indicator units 17. The recording unit 16 of the energy cabinet 10 is electrically connected to the control unit 14 and is used to record the on-site condition of the energy cabinet 10 to confirm whether maintenance personnel have removed the abnormal portable battery 30. In the first embodiment, when the control unit 14 of the energy cabinet 10 receives an unlocking command through the cloud communication unit 15, the control unit 14 further activates the recording unit 16 to start recording, thereby generating monitoring recording information, and the control unit 14 sends the monitoring recording information to the cloud server 20 through the cloud communication unit 15. In the second embodiment, when the unlocking time arrives and the abnormal portable battery 30 is unlocked, the control unit 14 will activate the recording unit 16 to start recording, thereby generating the monitoring recording information, and the control unit 14 will send the monitoring recording information to the cloud server 20 through the cloud communication unit 15. In this way, the on-site condition of the energy cabinet 10 can be monitored through the recording unit 16, preventing the theft of the abnormal portable battery 30.

[0082] Furthermore, when maintenance personnel complete maintenance work, they can use the application on the mobile device 51 to generate maintenance completion information, which is then sent to the cloud server 20. Upon receiving this maintenance completion information, the cloud server 20 generates and sends a stop recording command to the energy cabinet 10. When the control unit 14 receives the stop recording command through the cloud communication unit 15, it controls the recording unit 16 to stop recording and cease transmitting the monitoring recording information to the cloud server 20. This suspends on-site monitoring of the energy cabinet 10, reducing energy consumption.

[0083] Please see Figure 3A and Figure 5 As shown, the indicator units 17 are respectively disposed next to the battery receiving slots 11 and electrically connected to the control unit 14. When the energy cabinet 10 receives an unlock command sent by the cloud server 20, the control unit 14, in addition to unlocking the abnormal portable battery 30, further controls the indicator unit 17 of the battery receiving slot 11 corresponding to the abnormal portable battery 30 to display a warning light. This is used to remind the user and prevent the user from accidentally taking the abnormal portable battery 30.

[0084] For example, under normal circumstances, the indicator units 17 display a green light. However, when the power cabinet 10 receives an unlock command sent by the cloud server 20, the power cabinet 10 will unlock the abnormal portable battery 30 and control the indicator unit 17 corresponding to the abnormal portable battery location to display a red light to warn the user and prevent accidental removal.

[0085] In summary, this description merely illustrates the implementation methods or embodiments of the technical means employed by the present invention to solve the problem, and is not intended to limit the scope of the present invention. That is, all equivalent changes and modifications made in accordance with the wording of the claims of the present invention, or within the scope of the present invention, are covered by the scope of the present invention.
