In one embodiment, battery compartment 16 is provided with a protective cover having an interior 161 that matches the configuration of second battery 12, the protective cover being removably attached to battery compartment 16. For example, if the receptacle 162 of the battery compartment 16 is not sealed during the flight of the unmanned aerial vehicle, the batteries in the battery compartment 16 may be exposed and may be susceptible to environmental influences that may cause failure. The battery compartment 16 is therefore provided with a protective cover that will protect the batteries placed within the battery compartment 16. Secondly, if the first battery 11 and the second battery 12 are stacked to a length greater than the length of the inner cavity 161 of the battery compartment 16, the outermost portion of the second battery 12 is exposed outside the battery compartment 16. Considering the structure of the second battery 12 exposed outside the battery compartment 16, the structure of the inner cavity of the protective cover is designed to match with the structure of the second battery 12, and the protective cover can completely wrap the second battery 12 exposed outside the battery compartment 16. Specifically, the second battery 12 is a cube, and the inner cavity of the protective cover is also a cube. Further, the protective cover and the battery compartment 16 can be correspondingly provided with a female opening 15 and a buckle 14, so that the protective cover and the battery compartment 16 can be clamped through the female opening 15 and the buckle 14, and the connection between the protective cover and the battery compartment 16 is reinforced.

In one embodiment, the first battery 11 further comprises a smart battery management system, and the second battery 12 further comprises a smart battery management module, which is connected to the smart battery management system via the signal interface 134. The intelligent battery management module is configured to collect battery information corresponding to the second battery 12, and transmit the battery information to the intelligent battery management system through the signal interface 134; the intelligent battery management system is used for receiving the battery information of the second battery 12 and collecting the battery information of the first battery 11 so as to monitor the battery information of all the batteries. Illustratively, the battery information includes information such as battery capacity, remaining capacity, battery temperature, usage times and abnormal data, and after the intelligent battery management module collects the battery information corresponding to the second battery 12, the intelligent battery management module transmits the battery information to the intelligent battery management system through all signal interfaces 134 between the second battery 12 and the first battery 11. After receiving the battery information of each battery, the intelligent battery management system displays part of the battery information on the LED display screen of the first battery 11. The intelligent battery management system adds the residual electric quantity of all batteries in the battery bin 16 to obtain the total residual electric quantity, and sends the total residual electric quantity to the flight control system of the unmanned equipment, so that the flight control system can estimate the endurance time of the unmanned equipment according to the total residual electric quantity and the flight power. Further, the intelligent battery management system may determine, by receiving the battery information, which of the battery information of the second battery 12 is not normally uploaded, determine that the signal interface 134 of the second battery 12 is abnormal, and then start the backup signal interface 134 of the second battery 12, so as to continue to transmit the battery information through the backup signal interface 134, thereby ensuring communication reliability.

It should be noted that the intelligent battery management module configured by the second battery 12 does not have complete intelligent management power, and it is not usable alone, and needs to be used together with the intelligent battery management system of the first battery 11. The intelligent battery management system has the functions of voltage, current and temperature measurement, protection, communication, SOC and SOH estimation, balance management, abnormal protection and alarm, charge and discharge management, log recording and the like. When the intelligent battery management system is used with the intelligent battery management module in a matched mode, the intelligent battery management system can manage the states of all batteries in the battery bin 16, and the intelligent battery management system further comprises a function of communicating with the unmanned equipment and the intelligent remote control equipment so as to transmit the battery states to the unmanned equipment and the intelligent remote control equipment in real time. In order to prolong the service life of the battery, when the residual electric quantity of the battery is lower than a preset threshold value, the intelligent battery management system automatically locks the battery, and the battery can not supply power to the unmanned equipment any more.

Further, the intelligent battery management module includes a safety management unit for managing safety of the corresponding second battery 12, and has functions of charge and discharge management, log recording, and protection. When the smart battery management system and the smart battery management module are connected through the signal interface 134, the smart battery management system may read the log of each safety management unit to obtain information such as a battery code, an activation date, a number of times of use, a charge/discharge current, and a service life. It should be noted that the safety management unit has a function of independently recording the log, but does not have a function of directly reading the log, that is, the intelligent battery management module needs to be used in cooperation with the intelligent battery management system.

On the other hand, the present embodiment provides an unmanned aerial vehicle, where the unmanned aerial vehicle includes a flight control system and the unmanned aerial vehicle battery system mentioned in the foregoing embodiment, the flight control system is connected to the unmanned aerial vehicle battery system, and the flight control system can obtain battery information, such as the remaining power, uploaded by the unmanned aerial vehicle battery system in real time, so as to adjust flight parameters of the unmanned aerial vehicle according to the battery information. It should be noted that the socket 162 of the battery compartment 16 is upward arranged on the unmanned device in fig. 1, but in practice, the battery compartment 16 may also be transversely arranged on the unmanned device, and the corresponding first battery 11 and second battery 12 are stacked side by side when the battery compartment 16 is transversely arranged. The drone is able to fit one first battery 11 and at least one second battery 12, the threshold number of second batteries 12 fitted being dependent on the drone load threshold, the battery compartment 16 size and the charging capacity limit of the intelligent battery management system on the software. The unmanned equipment can freely configure the number of the second batteries 12 within the corresponding threshold value of the number of the assemblies according to the navigation requirement, so as to realize the function of adjusting the battery capacity according to the requirement.

In summary, according to the embodiment of the application, the first battery and the second battery are connected in parallel to expand the battery capacity of the large unmanned device, and the navigation capacity of the unmanned device is improved. The battery capacity can be adjusted according to the number of the second batteries connected in parallel, so that the battery capacity of the unmanned equipment can be adjusted according to requirements in different operation scenes, the time-flight capability of the unmanned equipment can be adjusted flexibly, and the operation flexibility of the unmanned equipment is improved.
