In one embodiment, theexternal power supply 200 is an alternating current power supply, for example, a main supply.

supply conversion unit 12 includes an alternating current-direct current (AC-DC)conversion unit 121 and a direct current-direct current (DC-DC)conversion unit 123.

The AC-DC conversion unit 121 converts an alternating current, which is provided by theexternal power supply 200 and output by the power input interface 11, to a direct current and output the direct current to the DC-DC conversion unit 123. The DC-DC conversion unit 123 is electrically connected with the AC-DC conversion unit 121 and thecontrol circuit 15. Under the control of thecontrol circuit 15, the DC-DC conversion unit 123 processes the direct current output by the AC-DC conversion unit 121 and converts the direct current to a charging signal required by thebattery 20. In one embodiment, the charging signal required by thebattery 20 may include at least one of the followings: a charging voltage and a charging current. - It can be understood that, in some embodiments, the
external power supply 200 may be a direct current power supply. That is, theexternal power supply 200 may output a direct current having a constant voltage or constant current to the power input interface 11. In this way, the AC-DC conversion unit 121 may not be required. That is, the powersupply conversion unit 12 may only include the DC-DC conversion unit 123.

Thecontrol circuit 15 controls the DC-DC conversion unit 123 in accordance with the charging information of thebattery 20 obtained by thesignal interface 14, and intelligently adjusts the charging signal output by the DC-DC conversion unit 123 to safely charge thebattery 20. For example, thecontrol circuit 15 may intelligently adjust the charging signal output by the DC-DC conversion unit 123 in accordance with the maximum charging voltage and with the maximum charging current of thebattery 20. For another example, if thecontrol circuit 15 acquires, through thesignal interface 14, a current temperature of thebattery 20 higher than a preset temperature value, thecontrol circuit 15 can control the DC-DC conversion unit 123 to temporarily stop outputting the charging signal, until the temperature of thebattery 20 is restored to a normal range. For still another example, thecontrol circuit 15 may acquire current battery capacity of thebattery 20 in real time through thesignal interface 14, and re-adjust the charging signal output by the DC-DC conversion unit 123, until thebattery 20 is fully charged. - It can be understood that the
control circuit 15 may further intelligently identify and authenticate thebattery 20 in accordance with the charging information of thebattery 20. That is, only identifiedbattery 20 can be charged or be charged with a large current. When thecontrol circuit 15 determines, in accordance with the charging information of thebattery 20, that thecharger 10 cannot charge thebattery 20, that is, thecharger 10 does not match the model of thebattery 20, thecontrol circuit 15 may control the DC-DC conversion unit 123 to stop outputting the charging signal, thereby protecting thebattery 20 and preventing damages to or explosions of thebattery 20. - The
charger 10 further includes a voltage andcurrent collection unit 16. In one embodiment, the voltage andcurrent collection unit 16 electrically connects the powersupply conversion unit 12 and thepower output interface 13. Further, the voltage andcurrent collection unit 16 electrically connects to the DC-DC conversion unit 123, thepower output interface 13, and thecontrol circuit 15. The voltage andcurrent collection unit 16 collects voltage information and current information of a charging signal output by the DC-DC conversion unit 123 and sends the collected voltage information and the current information to thecontrol circuit 15, so that thecontrol circuit 15 can monitor, in real time, the charging signal output by the DC-DC conversion unit 123. In some embodiments, the voltage andcurrent collection unit 16 may not be connected to thepower output interface 13. That is, the voltage andcurrent collection unit 16 may only connect to the DC-DC conversion unit 123 and thecontrol circuit 15. - The
charger 10 may further be compatible with a non-smart battery. For example, thebattery 20 may not have a self-balancing function. The non-smart battery includes multiple sets of battery cores connected in series or in parallel. At this point, thecharger 10 further includes abalance charging interface 17 and a battery corevoltage collection unit 18. Thebalance charging interface 17 electrically connects to the non-smart battery through a cable, and then performs balance charging control over respective sets of battery cores of the non-smart battery. The battery corevoltage collection unit 18 electrically connects thecontrol circuit 15 and thebalance charging interface 17. In this way, the battery corevoltage collection unit 18 may electrically connects to the non-smart battery through thebalance charging interface 17, and then communicates with the non-smart battery to enable the battery corevoltage collection unit 18 to acquire charging voltage information of the non-smart battery through thebalance charging interface 17. In this way, thecontrol circuit 15 can configure a corresponding charging signal in accordance with the charging voltage information of the non-smart battery collected by the battery corevoltage collection unit 18, then control the DC-DC conversion unit 123 to output the set charging signal through thepower output interface 13 to charge the non-smart battery. - In some embodiments, if the non-smart battery includes battery design information, the
control circuit 15 may also communicate with the non-smart battery through thesignal interface 14, then acquire charging information of the non-smart battery, and identify and authenticate the non-smart battery. That is, only when it passes through identification, the non-smart battery may be charged or charged with a large current. However, when thecontrol circuit 15 determines in accordance with charging information of the non-smart battery that thecharger 10 cannot charge the non-smart battery, that is, thecharger 10 does not match the model of the non-smart battery, thecontrol circuit 15 may control the DC-DC conversion unit 123 to stop outputting the charging signal, thereby protecting the non-smart battery, and preventing damages to or explosions of the non-smart battery. - In some embodiments, the
control circuit 15 may further control current voltages of respective sets of battery cores of the non-smart battery through thebalance charging interface 17 in accordance with the charging voltage information of the non-smart battery collected by the battery corevoltage collection unit 18. For example, when thebattery 20 is a non-smart battery, thecharger 10 further includes a batterycore balancing unit 19. The batterycore balancing unit 19 electrically connects thecontrol circuit 15 and thebalance charging interface 17. The non-smart battery may cause charging voltages of the respective sets of battery cores to be inconsistent with each other in the process of charging. Therefore, after the battery corevoltage collection unit 18 collects the voltage information of the respective sets of battery cores in the non-smart battery, thecontrol circuit 15 may start the batterycore balancing unit 19 in accordance with the voltage information of the respective sets of battery cores. For example, thecontrol circuit 15 causes the batterycore balancing unit 19 to discharge battery cores with higher voltages in the non-smart battery, to balance the charging voltages of the respective sets of battery cores in the non-smart battery, so that the respective sets of battery cores in the non-smart battery can have the fullest capacity. - The
aforementioned charger 10 may be work with a smart battery and a non-smart battery at the same time, that is, thecharger 10 can charge the smart battery and can also charge the non-smart battery. In this way, it is not necessary to set a correspondingcharger 10 for each type ofbattery 20, and thus the charger has more practical usage. In addition, thecharger 10 may further intelligently identify and authenticate the smart battery and the non-smart battery, to ensure that thecharger 10 only charges a matchingbattery 20, effectively protecting thebattery 20, extending the service life of thebattery 20, and preventing incidents. - The
charging system 100 is not limited to charging thebattery 20 of theaerial vehicle 300, which may also be applied to any other apparatuses with a battery, for example, vehicles, ships, and so on. - The foregoing disclosure is merely illustrative of the embodiments of the disclosure but not intended to limit the scope of the disclosure.
