1 and 2, in the battery management method of the drone 100 according to the embodiment of the present application, the drone 100 includes a battery management module 10 and a power supply interface 20, and the connected battery electrically connected to the power supply interface 20 is The UAV 100 is powered, and the battery management method includes the following steps:

011: The battery management module 10 communicates with the connected battery to obtain battery information of the connected battery;

012: The battery management module 10 communicates with the battery to be connected to obtain battery information of the battery to be connected; and

013: When the battery information of the battery to be connected matches the battery information of the battery that has been connected, the battery to be connected is electrically connected to the power supply interface 20 and then the battery is connected and the battery is supplied to the drone together with the connected battery 100 power supply.

The drone 100 of the embodiment of the present application can be powered by multiple batteries 200. The battery 200 includes the connected battery 210 and the battery 220 to be connected. The connected battery 210 is electrically connected to the power supply interface 20 to provide power for the drone 100 The battery management module 10 communicates with the connected battery 210 to obtain the battery information of the connected battery 210; the battery management module 10 communicates with the to-be-connected battery 220 to obtain the battery information of the to-be-connected battery 220; When the battery information of 220 matches the battery information of the connected battery 210, the battery 220 to be connected is electrically connected to the power supply interface 20 and then the battery 230 is connected and the battery 210 is connected to power the drone 100. . In other embodiments, the drone 100 includes a battery management module 10, a power supply interface 20, and a plurality of batteries 200, and the plurality of batteries 200 includes a battery 210 that has been connected and a battery 220 to be connected.

In other words, step 011 can be implemented by the battery management module 10 in cooperation with the battery 210 that has been connected. Step 012 may be implemented by the battery management module 10 in cooperation with the battery 220 to be connected. Step 013 can be implemented by the battery 220 to be connected in cooperation with the power supply interface 20. The motor management module 10 may be one or more general-purpose or special-purpose processors that can realize battery management.

Specifically, the connected battery 210 is the battery 200 that has been connected to the power supply interface 20 and supplies power to the drone 100, and the to-be-connected battery 220 is not connected to the power supply interface 20 and does not provide power to the drone 100. Powered by battery 200. After the drone 100 is connected to the connected battery 210 and the connected battery 210 is connected to the power supply interface 20, it can be powered on normally. When you want to add a new battery 220 to be connected, the drone 100 can perform When supplying power, first install the battery 220 to be connected to the drone 100. At this time, the battery management module 10 of the drone 100 can be electrically connected to the battery 220 to be connected, so that the battery management module 10 can be connected to the battery 220 to be connected. The battery 220 communicates to obtain the battery information of the battery 220 to be connected, and the battery management module 10 may also communicate with the connected battery 210 to obtain the battery information of the connected battery 210.

Among them, the battery information may include battery type and electrical parameters. The battery type mainly includes material information used by the battery 200. For example, the battery 200 is a lithium battery, a lithium polymer battery, etc., and the drone 100 generally has requirements for the battery type. When the battery 200 of the battery type that does not meet the requirements is connected, various safety problems may be caused, such as the safety problems of the battery 200 such as failure to supply power, damage to the battery 200, or even explosion of the battery 200. The electrical parameters mainly include at least one of the voltage and power of the battery 200. Of course, the electrical parameters may also include more information such as current, power, etc. The present application takes the electrical parameters including voltage and power as an example for description. When the electrical parameters of the battery 220 to be connected and the electrical parameters of the battery 210 are too different, the power supply may be abnormal. For example, when the difference between the voltage of the battery 220 to be connected and the voltage of the battery 210 connected is too large, the battery 220 to be connected and the battery 210 connected to each other will be charged mutually, thereby causing unnecessary power loss. Reduce the use efficiency of the battery 200; for another example, when the power of the battery 220 to be connected and the power of the connected battery 210 are too large, one battery 200 (the battery 200 with less power, such as the battery 210 is connected ) Is almost exhausted. Another battery 200 (such as the battery 220 to be connected) consumes only a small amount of power. The connected battery 210 not only cannot continue to supply power, but also increases the weight of the drone 100 and increases the power. The consumption affects the endurance of UAV 100. Therefore, when the difference between the power of the battery 220 to be connected and the power of the battery 210 is too large, the battery 200 with less power can be replaced to ensure the endurance of the drone 100.

After the battery management module 10 obtains the battery information of the battery 220 to be connected and the battery 210 that has been connected, it matches the battery information of the battery 220 to be connected and the battery 210 that has been connected. When the battery information of 210 matches, the connected battery 220 can be connected to the power supply interface 20 and then connected to the battery 230 to power the drone 100 together with the connected battery 210, and then connected to the battery 230 and connected The input battery 210 is essentially a battery 200 that is connected to the power supply interface 20 and supplies power to the drone 100, that is to say, the battery 230 is also connected to the battery 210 after it is connected. For example, the battery 220 to be connected as shown in FIG. 2 becomes the battery 230 after being connected after being matched with the battery 210 already connected. The battery 220 to be connected subsequently connected not only needs to be matched with the connected battery 210, but also needs to be matched with the rear connected battery 230 that is actually the connected battery 210.

Wherein, the battery information matching between the battery 220 to be connected and the battery 210 connected includes: the battery type of the battery 220 to be connected and the battery 210 to be connected are matched, for example, the battery to be connected 220 and the battery of the battery 210 are connected The types need to be the same. The connected battery 210 is a lithium battery, and the battery 220 to be connected also needs to be a lithium battery; or the electrical parameters of the battery 220 to be connected and the battery 210 to be connected match, for example, the battery 220 to be connected The difference between the electrical parameters and the electrical parameters of the connected battery 210 needs to be within a predetermined range; or, the battery type of the battery 220 to be connected matches the battery type of the connected battery 210, and the electrical parameters of the battery 220 to be connected Match the electrical parameters of the connected battery 210, for example, the battery type of the connected battery 220 and the connected battery 210 should be the same, and the difference between the electrical parameters of the connected battery 220 and the connected battery 210 Within the predetermined range. When the battery 220 to be connected does not match the battery 210 that has been connected, the battery 220 to be connected cannot be connected to the power supply interface 20 to supply power to the drone 100, which avoids the battery to be connected that does not match the battery 210 that has been connected The abnormal problem of the UAV 100 caused by 220 power supply to the UAV 100 occurs.

It is understandable that if the existing drone 100 adopts a scheme similar to the multiple batteries 200 of the present application for power supply, due to the lack of a reasonable battery management strategy, after the first battery 200 is switched on, if the first battery 200 needs to be switched on again, Two batteries 200, generally need to power off the drone 100, connect the second and later batteries 200 inserted, and then turn on the power to prevent abnormal power supply, which seriously affects the convenience of using the multi-battery 200 The battery 200 cannot be dynamically plugged and unplugged, and when the battery 220 to be connected and the battery 210 to be connected do not match, it may also cause the drone 100 to have abnormal problems such as power failure, damage to the battery 200, and reduced power supply efficiency.

The battery management module 10 of the present application can obtain the battery information of the battery 220 to be connected and the battery 210 that has been connected. There is no need to power off the drone 100 and then connect to the battery 220 to be connected, but on the drone 100 It can be plugged in when it is in the power state. After plugging in, it will not supply power immediately, but first determine whether the battery 220 to be connected and the battery 210 to be connected match. When the battery information of the battery 220 to be connected and the battery 210 to be connected match (that is, the battery information to be connected) Connecting the battery 220 will not cause abnormal power supply problems). Only connect the battery 220 to be connected to the power supply interface 20, which can not only realize dynamic plugging and insertion, but also the convenience of using the multi-battery 200, and it can prevent the connection with the connected battery. The abnormal problem of the UAV 100 caused by the unmatched battery 220 to be connected to the UAV 100 when the battery 210 is not matched to power the UAV 100, thereby ensuring the safety of power supply.

2 and 3, in some embodiments, the battery information of the battery 220 to be connected matches the preset information of the battery 200 that can power the drone 100, and the battery information of the battery 220 to be connected When the battery information matches the battery information of the connected battery 210, the battery 220 to be connected is electrically connected to the power supply interface 20 and then the battery 230 is connected and the battery 210 is connected to power the drone 100 together.

Specifically, in order to further confirm whether the battery 220 to be connected is suitable for the current drone 100, in addition to determining whether the battery information of the battery 220 to be connected and the battery 210 to be connected match, it is also necessary to determine the battery information of the battery 220 to be connected Whether it matches the preset information of the battery 200 capable of supplying power to the drone 100, where the preset information includes preset battery types and preset electrical parameters. Of course, the preset information may also include more battery performance parameters. Relevant information is not limited here, and this application only describes the preset information including the preset battery type and preset electrical parameters. The preset battery type refers to the type of battery 200 that can power the drone 100. For example, the battery type required by the drone 100 is lithium battery, lithium polymer battery, etc., and the preset electrical parameters include voltage, power, etc. Information, for example, the power supply voltage required by the UAV 100 is 5V, and the required power amount is 4000 mAh. Since there may be a match between the battery information of the battery 220 to be connected and the battery 210 that has been connected, the battery 220 to be connected is not applicable to the current situation of the drone 100. For example, the preset electrical parameters required by the drone 100 include The preset voltage, the preset voltage is 9V (V) to 11V, it is required that the voltage difference between the battery 220 to be connected and the battery 210 to be connected does not exceed 2V, and the battery 210 is connected after the user has used the drone 100 for a period of time , Due to the power loss of the connected battery 210, the actual power supply voltage is changed from the original 11V to 10V. When the voltage of the battery 220 to be connected is 12V, the voltage difference between the battery 220 to be connected and the battery 210 to be connected is 2V , To meet the matching standard of the battery information of the battery 220 to be connected and the battery 210 that has been connected. However, the voltage of the battery 220 to be connected is not within the preset voltage range of the battery that can supply power to the drone 100. Therefore, the battery 220 to be connected should not supply power to the drone 100.

In order to prevent the occurrence of the above situation, the drone 100 can match the battery information of the battery 220 to be connected with the preset information of the battery 200 that can power the drone 100, and the battery information of the battery 220 to be connected is the same as that of the connected battery. When the battery information of the input battery 210 matches, it is determined that the battery 220 to be connected meets the requirements of the battery 200 of the drone 100. Wherein, the battery information of the battery 220 to be connected to match the preset information of the battery 200 that can power the drone 100 includes: the battery to be connected 220 matches the preset battery type, for example, the battery to be connected 220 and the preset information The battery types need to be the same. If the preset battery type is a lithium battery, the battery to be connected 220 also needs to be a lithium battery; or, the battery to be connected 220 matches the preset electrical parameters, for example, the battery to be connected 220 and the preset battery The difference of the electrical parameters needs to be within a predetermined range; or, the battery type of the battery 220 to be connected matches the preset battery type, and the electrical parameters of the battery 220 to be connected match the preset electrical parameters, for example, the battery to be connected The input battery 220 and the preset battery type must be the same, and the difference between the battery 220 to be connected and the preset electrical parameter is within a predetermined range. After the matching is completed, the battery 220 to be connected to the power supply interface 20 is electrically connected to the battery 230 to be connected and the battery 210 is connected to power the drone 100 together. When the battery information of the battery 220 to be connected matches the preset information of the battery 200 that can power the drone 100, and the battery information of the battery 220 to be connected matches the battery information of the battery 210 that has been connected, the battery is to be connected The battery 220 is electrically connected to the power supply interface 20, and then the battery 230 is connected to the battery 230 and together with the connected battery 210 to supply power to the drone 100, which can further improve the safety of battery use.

In addition, when the drone 100 is connected to the first battery 200 to be powered on, since the battery 210 is not connected at this time, it is only necessary to determine whether the battery 200 is compatible with the preset battery 200 that can power the drone 100 The information can be matched to ensure that all batteries 200 connected to the UAV 100 are suitable for the current UAV 100, and the safety of the battery 200 is ensured.

In some embodiments, the electrical parameters include voltage and power. The electrical parameters of the battery 220 to be connected and the electrical parameters of the connected battery 210 may match the electrical parameters of the battery 220 to be connected and the electrical parameters of the connected battery 220. The absolute value of the difference between the electrical parameters corresponding to the battery 210 is within a predetermined range.

Specifically, the predetermined range includes a predetermined voltage range and a predetermined power range. When determining whether the electrical parameters of the battery 220 to be connected and the electrical parameters of the battery 210 to be connected match, the voltage and the voltage of the battery 220 to be connected can be determined respectively. Whether the absolute value of the difference between the voltage of the connected battery 210 is within the predetermined voltage range, and then determine whether the absolute value of the difference between the power of the battery 220 to be connected and the power of the connected battery 210 is within the predetermined power range, The absolute value of the difference between the voltage of the connected battery 220 and the voltage of the connected battery 210 is within a predetermined voltage range, and the absolute value of the difference between the power of the connected battery 220 and the power of the connected battery 210 When it is within the predetermined power range, it is determined that the electrical parameters of the battery 220 to be connected match the electrical parameters of the battery 210 that has been connected. For example, the predetermined voltage range is 0V to 3V, and the predetermined power range is 0 milliampere hour (mAh) to 1000mAh. The voltage of the battery 220 to be connected is 5V, and the power is 3000 mAh. The voltage of the connected battery 210 is 7V, and the power is 3500mAh. The absolute value of the difference between the voltage of the battery 220 to be connected and the voltage of the battery 210 that has been connected |5-7|=2V, within the predetermined voltage range, the voltage of the battery 220 to be connected and the voltage of the battery 210 that have been connected Match. The absolute value of the difference between the power of the battery 220 to be connected and the power of the battery 210 that has been connected |3000-3500|=500mAh, which is within the predetermined power range, the power of the battery 220 to be connected and the power of the battery 210 that have been connected Match. Therefore, the electrical parameters of the battery 220 to be connected match the electrical parameters of the battery 210 that has been connected. In this way, the drone 100 can accurately determine whether the electrical parameters of the battery 220 to be connected and the electrical parameters of the battery 210 that have been connected match.

When any electrical parameter of the battery 220 to be connected does not match the corresponding electrical parameter of the battery 210 connected, it is determined that the battery 220 to be connected does not match the battery 210 connected. For example, the electrical parameters include voltage and power, the predetermined voltage range is 0V to 2V, and the predetermined power range is 0 milliampere hour (mAh) to 1000mAh. The voltage of the battery 220 to be connected is 5V, and the power is 3000 mAh. The voltage of the connected battery 210 is 6V, and the power is 4500 mAh. The absolute value of the difference between the voltage of the battery 220 to be connected and the voltage of the battery 210 that has been connected |5-6| = 1V, within a predetermined voltage range, the voltage of the battery 220 to be connected and the voltage of the battery 210 that have been connected Match. The absolute value of the difference between the power of the battery 220 to be connected and the power of the battery 210 that has been connected |3000-4500|=1500mAh, which is not within the predetermined power range, the power of the battery 220 to be connected and the power of the battery 210 that have been connected The electric quantity does not match. Since there is an electrical parameter mismatch, it can be determined that the battery 220 to be connected and the battery 210 to be connected do not match. In this way, the matching accuracy of the battery 220 to be connected and the battery 210 already connected can be guaranteed.

2 to 4, in some embodiments, each battery 200 includes a battery cell 201, a control chip 202, a voltage conversion module 203, and a control switch 204, and the battery cell 201 connected to the battery 210 is used for output For the first voltage, the control switch 204 connected to the battery 210 is turned on so that the battery cell 201 connected to the battery 210 provides the first voltage to the drone 100; the drone 100 further includes a power conversion module 30; step 011 includes:

0111: The voltage conversion module 203 connected to the battery 210 is used to convert the first voltage output by the cell 201 connected to the battery 210 into a second voltage to provide the control chip 202 connected to the battery 210, the second voltage Lower than the first voltage;

0112: The power conversion module 30 converts the first voltage provided by the battery cell 201 connected to the battery 210 into a third voltage and provides it to the battery management module 10, the third voltage is lower than the first voltage; and

0113: The battery management module 10 communicates with the control chip 202 connected to the battery 210 to obtain battery information of the connected battery 210.

In other words, step 0111 and step 0112 can be implemented by the voltage conversion module 203 connected to the battery 210 in cooperation with the battery cell 201 connected to the battery 210, and step 0113 can be controlled by the battery management module 10 and the connected battery 210 The chip 202 is implemented in cooperation. Wherein, the voltage conversion module 203 and the power conversion module 30 may be any device capable of realizing high and low voltage conversion, and the voltage conversion module 203 and the power conversion module 30 may include a transformer or a voltage conversion chip.

Specifically, the battery 200 of the present application is a smart battery 200 with a control chip 202 (such as a Microcontroller Unit (MCU)). The control chip 202 can obtain battery information of the battery 200 in real time (such as the aforementioned battery type, Information such as electrical parameters). The voltage conversion module 203 (hereinafter referred to as the first voltage conversion module) that has been connected to the battery 210 can convert the first voltage provided by the battery cell 201 (hereinafter referred to as the first battery) that has been connected to the battery 210 The second voltage is converted into the second voltage and provided to the control chip 202 (hereinafter referred to as the first control chip) that has been connected to the battery 210, so that the first control chip is energized to work. Since only the normal operation of the first control chip needs to be maintained, the second voltage can be used. Lower than the first voltage, for example, the first voltage is a strong current, such as 11.5V, and the second voltage can be a weak current, such as 5V. The power conversion module 30 can convert the first voltage output by the first cell into a third The voltage is used to supply power to the battery management module 10 of the drone 100. Since the battery management module 10 is separately supplied, the third voltage can be lower than the first voltage. For example, the first voltage is a strong current, such as 11.5V. The third voltage can be a weak current, such as 5V. The third voltage can be the same as or different from the second voltage. The battery management module 10 that works after power on can communicate with the first control chip that works after power on (the battery management module 10 It will not work if it is not powered on, and the first control chip will not work if it is not powered on), so the battery management module 10 can obtain the battery information of the connected battery 210 in the first control chip. In this way, the battery management module 10 and the control The chip 202 can communicate when it is connected to the weak current, so that the battery management module 10 can quickly obtain the battery information of the connected battery 210, only when the battery information of the battery 220 to be connected matches the battery information of the connected battery 210 , The battery 220 to be connected to the power supply interface 20 is electrically connected to the battery and then the battery 210 is connected to provide strong power to the drone 1000; or, only the battery information of the battery 220 to be connected is the same as that of the connected battery 210. When the preset information of the battery 200 that can supply power to the drone 100 matches, and the battery information of the battery 220 to be connected matches the battery information of the battery 210 already connected, the battery 220 to be connected is electrically connected to the power supply interface 20. The battery 230 is connected to the connected battery and the unmanned aerial vehicle 100 is supplied with power together with the connected battery 210.

Referring to FIG. 2, FIG. 3, and FIG. 5, in some embodiments, before the battery 200 is used as the connected battery 210 to power the drone 100, the battery 200 management method includes:

014: The voltage conversion module 203 of the battery 200 converts the first voltage output by the cell 201 of the battery 200 into a second voltage to provide the control chip 202 of the battery 200 and the battery management module 10;

015: The battery management module 10 communicates with the control chip 202 of the battery 200 to obtain battery information of the battery 200;

016: When the battery information of the battery 200 matches the preset information of the battery 200 that can power the drone 100, the control switch 204 of the battery 200 is turned on to connect the battery 200 to power the drone 100.

In other words, step 014 can be implemented by the voltage conversion module 203 in cooperation with the battery cell 201, step 015 can be implemented by the battery management module 10 and the control chip 202, and step 016 can be implemented by the control switch 204.

Specifically, before the battery 200 is used as the connected battery 210 to power the drone 100 (that is, there is no connected battery 210 at this time, and the drone 100 is ready to be connected to the first battery 200 for power-on), the battery The first voltage (strong current) provided by the battery cell 201 of the 200 will be converted into the second voltage (weak current) by the voltage conversion module 203 of the battery 200 and provided to the control chip 202 of the battery 200 so that the control chip 202 is at the second voltage Work down. The control chip 202 controls the control switch 204 of the battery 200 to be turned off, so that the cell 201 of the battery 200 is disconnected from the power supply interface 20 of the drone 100, so as to prevent the battery 200 from directly supplying power to the drone 100 at the first voltage. The control switch 204 may be a field effect transistor, such as a metal-oxide semiconductor FET (MOS-FET for short). At this time, since the cell 201 of the battery 200 does not directly supply power to the drone 100 with the first voltage, the power conversion module 30 cannot convert the first voltage to the third voltage to provide to the battery management module 10. At this time, the battery The voltage conversion module 203 of the 200 can convert the first voltage (strong current) provided by the cells 201 of the battery 200 into a second voltage (weak current), and provide the second voltage (weak current) to the battery management module 10 of the drone 100 to form the battery management module 10 Supply weak electricity. After the battery management module 10 works under the second voltage (weak current), the battery management module 10 can communicate with the control chip 202 to obtain battery information from the control chip 202, and determine whether the battery information is compatible with the power supply for the drone 100 The preset information of the battery (such as the aforementioned preset battery type and preset electrical parameters) matches. When the battery information matches the preset information, the battery management module 10 can issue a switch-on instruction to the control chip 202. The control chip 202 controls the control switch 204 of the battery 200 to be turned on, so that the cell 201 of the battery 200 is connected to the power supply interface 20 of the drone 100, so that the cell 201 of the battery 200 uses the first voltage as the drone 100. Power supply (power supply), at this time, the first battery 200 is used as the connected battery 210 to power the drone 100 (power supply), and the voltage conversion module 203 of the battery 200 does not need to be the drone 100 anymore The battery management module 10 provides a weak current at the second voltage. After that, if the battery management module 10 still needs to communicate with the control chip 202 of the first battery 200 to obtain the battery information of the first battery 200, the power conversion module 30 of the drone 100 will The voltage is converted into a third voltage to supply weak current to the battery management module 10. In a weak current environment, the battery management module 10 communicates with the control chip 202 of the first battery 200. In this way, the battery management module 10 may first determine whether the battery information matches the preset information of the battery 200 that supplies power to the drone 100 before the battery cell 201 of the battery 200 uses the first voltage to supply power to the drone 100, so as to ensure Only the battery 200 applicable to the drone 100 can supply power to all the components of the drone 100 with the first voltage.

In addition, when the first battery 201 provides the first voltage to supply power to the drone 100, the power conversion module 30 provided inside the drone 100 can convert the first voltage into the voltage required by the components inside the drone 100 In this way, the various components in the drone 100 operate normally at their respective operating voltages. For example, if the first voltage is 11.5V, the power conversion module 30 can convert the first voltage into 5V, 7V, 12V, etc., and provide them to the battery management module 10, flight control system, power unit and other components of the drone 100 respectively to enable They work normally.

0121: The voltage conversion module 203 of the battery 220 to be connected is used to convert the fourth voltage output by the cell 201 of the battery 220 to be connected into a fifth voltage to provide to the control chip 202 of the battery 220 to be connected, the fifth voltage Lower than the fourth voltage;

0122: The battery management module 10 communicates with the control chip 202 of the battery 220 to be connected to obtain battery information of the battery 220 to be connected.
