[0001] The embodiments disclosed herein generally relate to the field of robotic equipment technology, and more specifically, to a battery module and an autonomous mobile robot. Background Technology

[0002] In actual use, the battery pack of autonomous mobile robots may have a shortened lifespan due to changes in ambient temperature, long-term storage, and incorrect operation such as overcharging and over-discharging, thereby increasing the product's operating costs.

[0015] In some embodiments, the status information includes temperature information indicating the temperature value of the cell module, and the control module is further configured to disconnect the charging switch and the discharging switch in response to determining that the temperature value indicated by the temperature information is less than a protection threshold.

[0016] In some embodiments, the battery module further includes a heating switch and a heating assembly, the heating switch being electrically connected to the charger and the heating assembly being coupled to the cell module, and wherein a control module is electrically connected to the heating switch and configured to: turn on the heating switch based on a heating command received from an external load to allow the heating assembly to heat the cell module; and allow the charging switch and the discharging switch to turn on in response to determining that the temperature value indicated by temperature information is higher than a protection threshold.

[0033] As described above, conventional battery pack designs are relatively simple and only enable charging and discharging. The battery pack lacks independent charging and discharging interfaces, thus preventing separate control of the battery charging / discharging modes and resulting in a lack of intelligent management capabilities. Embodiments of this disclosure provide a battery module and an autonomous mobile robot to at least partially address the aforementioned problems. In the following sections, [further details will be provided]. Figure 1 The principles of this disclosure are described.

[0034] Figure 1 The illustration shows application diagrams of autonomous mobile robots according to some embodiments of the present disclosure. For example... Figure 1 As shown, the battery module 100 described herein includes a cell module 1. The cell module 1 serves as a unit for storing electrical energy, and the cell module 1 includes at least one cell 11.

[0035] refer to Figure 1In some embodiments, the charging switch 2 is electrically connected to the cell module 1 and the charger 200. When the charging switch 2 is turned on, the charger 200 is adapted to charge at least one cell 11 in the cell module 1. The discharging switch 3 is electrically connected to the cell module 1 and the external load 300. The discharging switch 3 is configured to be turned on simultaneously with the charging switch 2, so that when the discharging switch 3 and the charging switch 2 are turned on simultaneously, the charger 200 can charge the cell module 1 and the cell module 1 can supply power to the external load 300 simultaneously. In this way, the battery module 100 according to the embodiments of the present disclosure simultaneously supports a charge and discharge operating mode.

[0036] refer to Figure 1 In some embodiments, the control module 4 is electrically connected to the charging switch 2 and the discharging switch 3. The control module 4 serves as the core processing unit in the battery module 100. The control module 4 is adapted to acquire load permission information associated with the external load 300. The control module 4 is adapted to control the opening and closing state of the discharging switch 3 based at least on the load permission information and permission confirmation information for the load permission information.

[0037] The control module 4 according to embodiments of this disclosure can be any type of control device currently known or available in the future, and the embodiments of this disclosure do not limit this. For example, in some embodiments, the control module 4 can be a microcontroller unit (MCU). In other embodiments, the control module 4 can also be other programmable control devices such as a digital signal processor (DSP), a field-programmable gate array (FPGA), and a central processing unit (CPU). In still other embodiments, the control module 4 can also include a control board based on a DSP, FPGA, or CPU, etc.

[0038] According to the battery module 100 of the embodiments of this disclosure, since the control module 4 is electrically connected to the charging switch 2 and the discharging switch 3, and the discharging switch 3 is allowed to be turned on simultaneously with the charging switch 2, the control module 4 can separately control the charging working mode and the discharging working mode, and the battery module 100 supports both charging and discharging working modes simultaneously. Furthermore, since the control module 4 can control the opening and closing state of the discharging switch 3 based at least on load permission information and permission confirmation information for the load permission information, the battery module 100 can prevent the cell module 1 from supplying power to loads that have not passed permission confirmation, thereby realizing load permission management function and possessing intelligent management capabilities.

[0039] In some embodiments, the battery module 100 may further include a heating switch 81 and a heating component 82. The heating switch 81 may be electrically connected to the charger 200 and the heating component 82. The heating component 82 may be coupled to the cell module 1 and is adapted to heat the cell module 1 when the heating switch 81 is turned on. For example, in some embodiments, the heating component 82 may include a heating film that is capable of generating heat when energized.

[0040] The charging switch 2, discharging switch 3, and heating switch 81 according to embodiments of this disclosure can be various types of switches currently known or available in the future, and the embodiments of this disclosure do not limit this. For example, in some embodiments, the charging switch 2, discharging switch 3, and heating switch 81 may include a switching device composed of a metal-oxide-semiconductor field-effect transistor (MOSFET) and a controller. The switching device can be disconnected in the event of an open circuit and turned on in the event of a short circuit.

[0041] In some embodiments, the charging switch 2, discharging switch 3, and heating switch 81 may further include discrete devices such as reed switches, relays, solid-state relays, and MOSFETs. In other embodiments, the charging switch 2, discharging switch 3, and heating switch 81 may further include a switching circuit constructed from the aforementioned discrete devices. In still other embodiments, the charging switch 2, discharging switch 3, and heating switch 81 may also be a switching module integrated from multiple discrete devices, and the switching module is used to control the current flow.

[0042] refer to Figure 1 In some embodiments, the battery module 100 may further include a voltage monitoring module 5. The voltage monitoring module 5 can be electrically connected to the charging switch 2 and the charger 200. It can be seen that the voltage monitoring module 5 is located on the charging channel, therefore the voltage monitoring module 5 is adapted to monitor the charging voltage output by the charger 200. The voltage monitoring module 5 is adapted to transmit voltage information regarding the charging voltage to the control module 4 to wake up the control module 4.

[0043] refer to Figure 1In some embodiments, the control module 4 is electrically connected to the voltage monitoring module 5 and the power button 400. The control module 4 can be configured to respond to receiving monitoring information from the voltage monitoring module 5 indicating that a charging voltage has been detected. In some embodiments, alternatively or additionally, the control module 4 can be configured to control the discharge switch 3 to turn on in response to a power-on message indicating that the power button 400 of the external load 300 has been pressed. The external load 300 may include, for example, electronic components or motors of an autonomous mobile robot. It is understood that the control module 4 may be in a dormant state before the battery module 100 is powered on, and therefore typically needs to be woken up by a short press of the power button 400 or by detecting a charging voltage on the charging channel. In this way, the control module 4 can control the discharge switch 3 to turn on, so that the external load 300 can be powered by the cell module 1, and the external load 300 will undergo authorization verification after being powered on.

[0044] In some embodiments, the battery module 100 may further include a timer. The timer may be coupled to the control module 4. The timer may start timing based on a timing command from the control module 4, provided that at least one of the following conditions is met: the power button 400 of the external load 300 is pressed, or the control module 4 stops communication between the communication module 6 and the external load 300. In this way, when the power button 400 is pressed or when the control module 4 stops communication between the communication module 6 and the external load 300, the control module 4 can issue a timing command to the timer and begin timing. The purpose of the timer will be described below.

[0045] refer to Figure 1 In some embodiments, the communication module 6 can be electrically connected to the control module 4 and the external load 300 via a communication interface. For example, in some embodiments, the communication interface may include an RS485 interface. In other embodiments, the communication interface may also include an Ethernet (ETH) interface, a Controller Area Network (CAN) interface, a Local Interconnect Network (LIN) interface, a Thunderbolt interface, an Integrated Circuit Bus (IIC) interface, a Serial Peripheral Interface (SPI), RS232, a Peripheral Component Interconnect Fast Bus (PCIe) interface, a Universal Serial Bus (USB) interface, etc.

[0046] refer to Figure 1In some embodiments, the communication module 6 may be coupled to the control module 4 and is adapted to communicate with the external load 300 when the battery module 100 is connected to the external load 300, in order to at least obtain load permission information associated with the external load 300 and permission confirmation information for the load permission information. After the control module 4 is woken up, the control communication module 6 is in a listening state, waiting for the external load 300 to be powered before communicating with the external load 300. When the external load 300 is powered, the external load 300 and the control module 4 exchange keys through the communication module 6 for two-way permission confirmation.

[0047] refer to Figure 1 In some embodiments, the authorization confirmation information may include user authorization confirmation information and factory authorization confirmation information. When the power button 400 is pressed, the control module 4 can send a timing command to the timer and start timing. The control module 4 can also be configured to: in response to receiving user authorization confirmation information within a predetermined time, keep the discharge switch 3 on to allow the cell module 1 to continue supplying power to the external load 300. The predetermined time for the timer may, for example, include 3 minutes. If the control module 4 receives factory authorization confirmation information within the predetermined time, it keeps the discharge switch 3 on to continue supplying power to the external load 300, and the control module 4 also allows adjustment of the battery parameters of the battery module 100.

[0048] refer to Figure 1 In other embodiments, the control module 4 may also be configured to: in response to not receiving authorization confirmation information within a predetermined time, disconnect the discharge switch 3 to stop supplying power to the external load 300. Furthermore, the control module 4 may also be configured to: in response to not receiving authorization confirmation information within a predetermined time, stop the communication module 6 from communicating with the external load 300 for a first predetermined duration. The first predetermined duration of the timer may, for example, include 3 minutes. When authorization confirmation is not received within the predetermined time, the control module 4 disconnects the discharge switch 3 of the discharge channel to stop supplying power to the external load 300, and the control module 4 starts the timer. It is understood that since the control module 4 can issue a timing command to the timer and start timing while the communication module 6 is not communicating with the external load 300, the control module 4 can control the communication module 6 to be unable to communicate within the first predetermined duration, thereby preventing malicious use of the battery module 100 by repeatedly performing authorization confirmations.

[0049] In summary, the battery module 100 according to the embodiments of this disclosure implements load permission management function and has intelligent management capabilities. Furthermore, the battery module 100 has unique permission confirmation conditions and its circulation can be tracked.

[0050] refer to Figure 1In some embodiments, the control module 4 can also be configured to, upon receiving authorization confirmation information, provide battery parameters of the battery module 100 to the external load 300 in response to a query command from the external load 300. In this way, the control module 4 can identify and report the status of the battery module 100, and the external load 300 can query the battery parameters of the battery module 100 (e.g., voltage, current, temperature, etc. of the cell 11). Furthermore, the external load 300 can also query the status of the charging switch 2, discharging switch 3, and heating switch 81 of the battery module 100 via the communication module 6, and the external load 300 can control the opening and closing states of the charging switch 2, discharging switch 3, and heating switch 81 via commands.

[0051] refer to Figure 1 In some embodiments, the communication module 6 can also be electrically connected to the charger 200 via a communication interface, and the battery module 100 is adapted to communicate with the charger 200 when connected to the charger 200. For example, the control module 4 can transmit battery parameters of the battery module 100 to the charger 200, which can control its output charging voltage and current to avoid damaging the cell module 1.

[0052] refer to Figure 1 In some embodiments, the battery module 100 may further include a monitoring circuit 7. The monitoring circuit 7 may be electrically connected to the cell module 1 and the control module 4. The monitoring circuit 7 is adapted to acquire status information of at least one cell 11 and can transmit the status information to the control module 4. The control module 4 may also be configured to control the current and charge / discharge state in the cell module 1 based on the status information of at least one cell 11. For example, in some embodiments, when a voltage difference exists between at least one cell 11, the control module 4 may control the monitoring circuit 7 to regulate the current between at least one cell 11.

[0053] refer to Figure 1 In some embodiments, the control module 4 can also be configured to transmit status information to the external load 300 via the communication module 6. In this way, the external load 300 can query status information such as low temperature alarm information and low temperature alarm unlock information through the communication interface.

[0054] refer to Figure 1Furthermore, the status information may also include temperature information indicating the temperature value of the battery cell module 1. The control module 4 may also be configured to disconnect the charging switch 2 and the discharging switch 3 in response to determining that the temperature value indicated by the temperature information is less than a protection threshold. In this way, when the temperature of the battery cell module 1 is lower than the charge / discharge protection threshold, the control module 4 sets the low-temperature alarm register and disconnects the charging switch 2 and the discharging switch 3, thereby preventing the use of the battery cell module 1 in low-temperature environments. In addition, as mentioned above, the external load 300 can also query the low-temperature alarm information through the communication module 6.

[0055] refer to Figure 1 Furthermore, the control module 4 can also be electrically connected to the heating switch 81 and can be configured to turn on the heating switch 81 based on a heating command received from the external load 300, so that the heating component 82 heats the cell module 1. The control module 4 can also, in response to determining that the temperature value indicated by the temperature information is higher than a protection threshold, allow the charging switch 2 and the discharging switch 3 to turn on. According to embodiments of this disclosure, the battery module 100 can utilize external electrical energy to heat the cell module 1, achieving the purpose of actively intervening in the temperature of the cell 11, so as to quickly restore the charging and discharging function of the cell module 1 in a low-temperature environment. When the temperature of the cell module 1 is higher than the charging / discharging protection threshold, the control module 4 will deactivate the low-temperature alarm and reset the control register. Since the charging switch 2 and the discharging switch 3 are turned on, the battery module 100 can charge and discharge normally. In addition, as mentioned above, the external load 300 can also query the low-temperature alarm unlocking information through the communication module 6.

[0056] refer to Figure 1 In some embodiments, the control module 4 may also be configured to disconnect the discharge switch 3 to stop power supply to the external load 300 based on the satisfaction of at least one of the following conditions: and to start the inactive timer in the timer. For example, satisfying the condition may include determining that the duration for which the power button 400 has been pressed is equal to or greater than a second predetermined duration; and / or receiving a delayed disconnect command from the external load 300; and / or receiving a power-off command from the external load 300.

[0057] In the embodiments of this disclosure, when the power button 400 is pressed, the control module 4 receives the power button signal, and the timer starts counting when the power button 400 is pressed. On one hand, when the timer determines that the duration of the power button 400 being pressed is equal to or greater than a second predetermined duration (i.e., the duration of the long press), and the control module 4 does not receive a delayed disconnect command from the external load 300, then the control module 4 controls the discharge switch 3 to open and starts the no-operation timer. The second predetermined duration may, for example, include 15 seconds. On the other hand, when the timer determines that the duration of the power button 400 being pressed is equal to or greater than the second predetermined duration, and the control module 4 receives a delayed disconnect command from the external load 300, then the control module 4 controls the timer to restart counting the second predetermined duration. If the external load 300 does not issue a new delayed disconnect command, after the timer has recounted the second predetermined duration, the control module 4 controls the discharge switch 3 to open and starts the no-operation timer. If control module 4 receives another delayed disconnect command from external load 300, then control module 4 controls the timer to restart the second predetermined duration until no further delayed disconnect command is received from external load 300. On the other hand, if control module 4 receives a power-off command from external load 300, then control module 4 immediately controls discharge switch 3 to open and starts the no-operation timer.

[0058] refer to Figure 1 In some embodiments, the control module 4 may also be configured to enter a sleep state in response to the inactivity timer's duration being equal to or greater than a third predetermined duration. The third predetermined duration may, for example, include 7 days.

[0059] Continue to refer to Figure 1 The embodiments of this disclosure also provide an autonomous mobile robot, which includes: a battery module 100 according to any of the embodiments of this disclosure; an external load 300 electrically connected to the battery module 100; and a power button 400, a control module 4 electrically connected to the external load 300 and the battery module 100.

[0060] According to the embodiments of the autonomous mobile robot disclosed herein, since the control module 4 is electrically connected to the charging switch 2 and the discharging switch 3, and the discharging switch 3 is allowed to be turned on simultaneously with the charging switch 2, the control module 4 can separately control the charging working mode and the discharging working mode, and the battery module 100 supports both charging and discharging working modes simultaneously. Furthermore, since the control module 4 can control the opening and closing state of the discharging switch 3 based at least on load permission information and permission confirmation information for the load permission information, the battery module 100 can prevent the cell module 1 from supplying power to loads that have not passed permission confirmation, thereby realizing load permission management functions and possessing intelligent management capabilities.
