Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] See also Figure 1 The present invention provides a circuit diagram of a charging device for a vertical aircraft, the charging device for the vertical aircraft at least comprises: a control module 101, an input module 102, a rectifier module 103, a DC conversion module 104 and an output module 105, the input module 102 is connected to the DC conversion module 104 through the rectifier module 103, the DC conversion module 104 is also connected to the output module 105, the output module 105 at least comprises a plurality of different standard interfaces, wherein:

[0032] A switch module is provided between the control module and the input module. When the control module determines that the battery to be charged meets the charging requirements, the switch module is turned on and a charging start instruction is sent to the input module.

[0033] The input module 102 is used to input an AC voltage; after receiving a charge start instruction, an AC voltage of 380V is input.

[0034] The rectifier module 103 is used to convert the AC voltage into a first DC voltage; the AC voltage is converted into a DC voltage through full-bridge rectification or half-bridge rectification;

[0035] The DC conversion module 104 is used to convert the first DC voltage into a second DC voltage; according to the charging requirement, the first DC voltage is converted into a second DC voltage that meets the charging requirement.

[0036] The output module 105 is used to charge different types of vertical aircraft using different standard interfaces according to the second DC voltage.

[0037] Figure 2 A schematic diagram of a charging device for a vertical aircraft according to another embodiment of the present invention is shown in FIG. Figure 2 As shown, the AC mains is input into the AC / DC rectifier module to output voltage DC1, and then the voltage DC1 is input into the DC / DC converter to output voltage DC2, and the voltage DC2 is input into the output power flexible distributor, which is connected to the charging gun and includes various types of interfaces for connecting different types of vertical aircraft.

[0038] Figure 3 A schematic diagram of different types of interfaces provided for an embodiment of the present invention, wherein the different types of interfaces at least include a GB / T 20234 interface, a J1772 interface, an IEC 62196 interface, a NACS interface, and a GEACS interface.

[0039] The charging interface of the charger should have good compatibility and should include at least the five types of interfaces mentioned above to meet the charging needs of eVTOLs with different standard interfaces at the base station.

[0040] Optionally, the charging device further includes a monitoring module, which is connected to the output module and is used to monitor the charging status of batteries of different types of vertical aircraft.

[0041] After the charger is connected to the eVTOL power battery, the main parameters of the power battery can be quickly read through the BMS (monitoring module). The charger management system can manage the charging and adjust the voltage and current during the charging process according to these parameters, so that the charger will not cause thermal runaway of the power battery during the charging process.

[0042] Optionally, the charging device further includes a display module, which is connected to the control module, and is used to display the charging status and charging amount according to instructions of the control module.

[0043] Optionally, the display module is an LCD display screen.

[0044] Optionally, the rectifier module includes at least a full-bridge rectifier circuit.

[0045] Optionally, the input module is used to input 380V AC voltage.

[0046] Optionally, the output module is used to output a maximum voltage of 1000V and a maximum power of 600kW.

[0047] Optionally, a mobile module is installed at the bottom of the charging device, and the mobile module is used to move the charging device.

[0048] Optionally, the charging device is a mobile horizontal pile body, and an incoming cable and an outgoing cable are respectively provided on both sides of the pile body.

[0049] The eVTOL charger system is the charging device for vertical aircraft. It is generally mobile and can be easily pushed to the eVTOL parking position for charging. That is, the main unit is installed on a movable platform, one end of the AC cable is led to the AC power supply of the station, and the charging pile is installed on the mobile platform. The charging gun on the charging pile is pulled from the charging pile to the eVTOL power battery interface for plugging and charging. This is why eVTOL requires that all nearby equipment must be at a safe distance.

[0050] like Figure 4 As shown, the main structure is a mobile horizontal pile body. Both sides of the pile body are equipped with incoming cable (AC 380V) input and outgoing cable (DC 200-1000V) output. There are 5 pairs of output cables, each pair of cables corresponds to a standard charging gun, and different standard interfaces are detailed in Figure 3 shown.

[0051] The charger of the charging device of the vertical aircraft is a horizontal structure, which is composed of a rectifier box and a DC conversion power unit (box), and a load-bearing mobile body.

[0052] Main structure content: see Figure 2 As shown:

[0053] Mains input + rectifier device (cabinet): mainly composed of AC / DC rectifier module, AC input circuit breaker, controller, etc.; the cable length can be adjusted according to needs, and the standard configuration is 10 meters.

[0054] DC conversion and power distribution stack (cabinet): mainly composed of DC converter, power distribution stack, system monitoring device, and local display screen, etc.

[0055] The device is also equipped with a DC charging gun and cable, including a control panel for each gun operation, etc. The standard cable length is 5 meters;

[0056] Mobile body: The equipment carrier body, wheels and handles (intelligent mobile body can be configured according to customer needs);

[0057] During charging, any gun (all equipped with liquid-cooled gun heads) can output electrical energy with a maximum DC voltage of 1000V and a maximum power of 600kW to meet the eVTOL's charging requirements of 4C or 5C.

[0058] The one-machine, multiple-gun configuration can meet five standard interface configurations respectively. In addition to the sockets meeting different standards, the connection protocols can be automatically switched in the control system to meet the charging needs of different types of eVTOLs.

[0059] The charging gun has 5 standard interfaces, each of which corresponds to a DC charging power channel, meeting the eVTOL connection charging of 5 types of charging standards.

[0060] In the embodiment of the present application, if four charging guns with the same standard interface are configured, when the eVTOL is configured with 2 to 4 battery modules, the charging guns can charge their respective rotor power battery modules respectively.

[0061] like Figure 5 As shown in the figure, given that the eVTOL parking apron safety requirements are relatively large (clearance space), generally up to 10 to 15 meters, it is more convenient to use a mobile horizontal dedicated charger. When the eVTOL at the station needs to be charged, the charger can be pushed to about 3 meters away from the eVTOL (approximately in the FATO final approach and take-off area) and then the charging gun can be pulled to connect the eVTOL charging interface for charging.

[0062] like Figure 6 As shown, after the eVTOL charger system automatically connects according to the interface (corresponding to the corresponding interface standard), the charging device of the vertical aircraft can automatically select the corresponding standard (the monitoring system has 5 types of standard interface protocols) for charging.

[0063] like Figure 7 As shown, the eVTOL battery stack is first tested. When it is detected that the eVTOL meets the charging requirements (combined with basic parameter values ​​such as SOH and SOC), the monitoring system can issue a command to operate the DC power supply to charge the eVTOL; otherwise, a warning will be issued to check whether the plug is properly connected (charging gun). The charging process can only continue after the fault is eliminated.

[0064] like Figure 7As shown, the eVTOL charger control system feeds back the standard interface information on the plug to the monitoring device, and the monitoring device distributes the energy according to the EMS energy management (power stack execution) to the corresponding standard interface on the plug to give the charging channel a certain amount of electric power.

[0065] The embodiment of the present application achieves charging the battery from 30% to 80% within 5 to 10 minutes, meeting the needs of frequent takeoff and landing of the eVTOL aircraft.

[0067]

[0068] The embodiments of the present application meet the needs of eVTOLs with different standard interfaces to come to a dedicated apron for charging / recharging. After high-voltage and high-power charging / recharging by the charging equipment in the embodiments of the present application, the high-speed, fast, high-frequency, and short-distance takeoff and landing requirements of the eVTOL operation are met.

[0069] Since eVTOL runs frequently, it takes about 20 minutes to pick up and drop off customers at each station, which is also the time for eVTOL to recharge. In this limited time, the embodiment of the present application requires at least 80% or more of the eVTOL battery capacity to be recharged.

[0070] In addition, from the perspective of the cost of charging facility construction, the output module 105 has a larger power battery capacity and higher charging power requirements. It can be configured to form up to four groups of independently operating power batteries, each corresponding to a set of rotors, so that four groups of chargers are required to charge the battery packs simultaneously during charging.

[0071] The charging device for a vertical aircraft provided by the present invention comprises at least: an input module, a control module, a rectifier module, a DC conversion module and an output module, wherein the input module is connected to the DC conversion module via the rectifier module, the DC conversion module is also connected to the output module, and the output module comprises at least a plurality of different standard interfaces, wherein: the control module is used to detect the battery status and parameter indicators of the vertical aircraft to be charged, and when the battery status meets the charging requirements, the input module is controlled to start charging; the input module is used to input AC voltage; the rectifier module is used to convert the AC voltage into a first DC voltage; the DC conversion module is used to convert the first DC voltage into a second DC voltage; the output module is used to charge different types of vertical aircraft using different standard interfaces according to the second DC voltage, and by setting a plurality of different types of interfaces, it is used to charge different types of vertical aircraft and meet the charging requirements of vertical aircraft with a plurality of different standard interfaces.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
