Description

Distributed Electric Energy Pods Network and Associated Elec trically Powered Vehicle
The present application relates to an external pod for a vehi cle and to a vehicle with a network of pods.
US 9845158 B2 shows a battery containment pod. The pod in cludes a body that is formed of a lightweight material. The body has an aerodynamic exterior shape and has an interior cavity formed in the lightweight material. The size and shape of the interior cavity are designed to accommodate one or more battery packs. A smooth exterior coating covers the exterior shape of the body. An attachment structure is formed in or on the body for allowing the body to be coupled to a flight vehi cle .
US 20120160957 A1 shows an external pod for an aircraft.
It is an object of this application to provide an improved pod for a vehicle, such as an aircraft.
The vehicle can refer to, though is not limited to, an elec tric unmanned aerial vehicle (UAV) , an electrically powered aircraft, an electric vertical take-off and landing (VTOL) flying passenger car, and a UAV that can operate in air, on land, or underwater.
It is believed that a network of interchangeable distributed external hydrogen fuel cell/battery hybrid electrical energy systems containment pods, also called as Distributed Electric Energy Pod (DEEP) can be used to support multiple improved ve hicle designs, such as aircraft designs. The distributed electric energy pods are also called inter changeable external hydrogen fuel cell/battery hybrid electri cal energy system containment pods, or fuel cell/battery pods for short.
The network of interchangeable distributed external hydrogen fuel cell/battery hybrid electrical energy systems containment pods enables smart and efficient power generation architec tures for different vehicle platforms, which in return yields an improved vehicle concept. The fuel cell/battery hybrid based distributed electric energy pods can be utilised as mul tiple systems in parallel, that is multiple pods operated in parallel, or as a single powering system to move and power an electrically powered vehicle.
The network of distributed electric energy pods also provides an enhanced power generation architecture for a vehicle with electric propulsion. The electric propulsion reduces the over all power required to move the vehicle. By combining of dif ferent sources of electric power with different technologies having different corresponding benefits and characteristics, in terms of specific energy, electrical current density, weight, and high efficiency, the network of distributed elec tric energy pods allows the vehicle to have extended opera tional flying range and extended operational flight autonomy as well as having greater part redundancy and back-up power sources to improve safety. Moreover, the network of distrib uted electric energy pods allows electrical flying solutions to reduce noise and carbon emissions as compared to vehicle designs with an internal combustion engine.
The application provides an interchangeable, distributed ex ternal hydrogen fuel cell/battery hybrid electrical energy systems containment pod for moving and propelling a vehicle, such as an aircraft, while the vehicle is in flight or on the ground .
The pod includes a nacelle and an energy storage and powering machine .
The nacelle comprises an enclosure for surrounding the energy storage and powering machine and a vehicle joining structure.
In detail, the enclosure is streamlined to allow the enclosure to move easily through the air. Put different, the shape of the enclosure is adapted for reduced drag.
The joining structure is attached to the enclosure for fixing the enclosure to a part of the vehicle, such as a wing, a body, or a fuselage of the vehicle. The wing refers to a hori zontal structure that sticks out from a side of the body of the vehicle. The wing supports the vehicle when the vehicle is flying .
The joining structure can attach the enclosure to an external part of the wing or attach the enclosure to the wing such that the enclosure forms a part of the wing. Similarly, the joining structure can attach the enclosure to an external part of the body or attach the enclosure to the body such that the enclo sure forms a part of the body.
This attachment is also done such that the pod can be removed easily and quickly from the vehicle. This is useful when the pod needs to be replaced.
Referring to the energy storage and powering machine, it in cludes a power generation module, a propulsion module, and an electronics module. The propulsion module includes an electric motor with a pro peller module, wherein the electric motor is connected to the propeller module.
In use, the electronics module activates the power generation module, wherein the power generation module provides electri cal energy to the electric motor.
The energised electric motor then moves and rotates blades of the propeller module, wherein the rotating blades draw air for moving the vehicle.
The pod is useful in that different numbers of the pod can be attached to the vehicle according to the power requirement of the vehicle. The pod can also be removed easily or quickly from the vehicle for maintenance or replacement of the pod when the pod is spent. In short, the pod can be utilised by the vehicle in different ways, according to the size, weight, and power requirement of the vehicle.
According to one aspect of the application, the power genera tion module includes a fuel cell stack with an energy storage module, and/or a hybrid battery pack.
In use, the fuel cell stack, together with the energy storage module, supplies electrical energy to the parts of the pod. In detail, the energy storage module provides hydrogen gas to the fuel cell stack, wherein the fuel cell stack uses the hydrogen gas to generate electrical energy and to transmit the gener ated electrical energy to the vehicle, namely to the electric motor of the propulsion module of the vehicle. The hybrid battery pack also supplies electrical energy to the electric motor.
Operationally, the power generation module provides two oper ating modes, namely a standalone mode and a hybrid mode. In the standalone mode, the electronics module activates either the fuel cell stack with the energy storage module or the hy brid battery pack to supply electrical energy to the electric motor. In the hybrid mode, the electronics module activates both the fuel cell stack with the energy storage module and the hybrid battery pack to supply electrical energy to the electric motor.
The hybrid battery pack can include different parts. It can include a lithium polymer (LiPo) battery, or a super-capaci tor, or an air-breathing battery, or other chemical energy storage technology, or combinations of the earlier-mentioned parts .
Referring to the propeller module, it can include one or more propellers or one or more electric ducted fans (EDF) .
The electronics module often includes an embedded processor, at least one health monitoring sensor, and/or an electrical and communication connectivity unit. In use, the health moni toring sensor measures a characteristic of the pod, such as temperature and later sends the measurement to the embedded processor. The embedded processor then generates an environ mental control signal according to the measurement of the health monitoring sensor. After this, the embedded processor sends the signal via the electrical and communication connec tivity unit for adjusting an environmental characteristic of the enclosure. The pod often includes a heat control module for controlling an internal temperature of the enclosure of the nacelle. In use, the pod is often subjected to extreme temperatures. The heat control module then controls and adjusts the enclosure internal temperature to ensure that parts within the enclosure are operating within a predetermined operating temperature range .
The heat control module can include a thermal isolation mate rial, and a ram air circulating device, and/or a heat recover ing system. In use, the thermal isolation material acts to shield parts within the enclosure from external extremely high or low temperature. The ram air circulating device is provided for circulating air within the enclosure for cooling equipment that is placed inside the enclosure. The heat recovering sys tem is used for transferring heat into the enclosure to pre vent the temperature within the enclosure from falling below a predetermined lower limit temperature .
The pod can include an electrical connector for receiving en ergy from an external power source.
In one implementation, the external power source comprises a solar power source, such as solar panels being mounted on top of the vehicle for receiving sunlight.
In another implementation, the external power source refers to an energy source of another pod. This energy source provides electrical power to supplement the energy supply of the pre sent pod.
Different configurations of attaching the pod to the vehicle are shown below. The application provides an improved vehicle, such as an air craft. The vehicle includes two wings and one or more of the above-mentioned pods. The pod is attached to the respective wing .
The vehicle often includes even number of pods. The pods are also often distributed such that vehicle is aerodynamically balanced .
The application provides a further vehicle. The vehicle in cludes a body or a fuselage, and one or more of the above pods, wherein each pod is attached to the body.
The vehicle often includes a centralized energy management unit. The centralized energy management unit is provided for activating the pod to supply electrical energy to a propulsion module of the pod.
In a case wherein the vehicle has more than one pod, the cen tralized energy management unit often activates the pods such that the pods provide an even distribution of electrical en ergy. As an example, the vehicle can include two pods. The centralized energy management unit activates each pod such that each pod supplies the same amount of electrical energy.
The application provides another vehicle. The vehicle includes two wings, a body or a fuselage, at least one of the above- mentioned first pod, and at least one of the above-mentioned second pod. The first pod is attached to a part of the wing while the second pod is attached to a part of the body.
The vehicle often includes an energy management unit for acti vating the first pod to provide electrical energy to a first propulsion module of the first pod and for activating the second pod to provide electrical energy to a second propulsion module of the second pod.
The activation can be done such that each pod provides the same amount of electrical energy.
The application also provides a method of providing electrical power to a vehicle.
The method includes a step of attaching one or more pods to wings or to a body or fuselage of the vehicle. Each pod con tains a hydrogen fuel cell, a hybrid battery and a propulsion module .
After this, one member of a group of each pod is activated to provide electrical power to the propulsion module. The group consisting of the hydrogen fuel cell, the hybrid battery, and a combination of the hydrogen fuel cell and the hybrid battery of each pod. In other words, the hydrogen fuel cell, or the hybrid battery, or both the hydrogen fuel cell and the hybrid battery are then activated to provide electrical power to the propulsion module.
In one aspect of the application, the attaching of the pods to the vehicle includes a step of attaching two or more pods to the vehicle.
The activating of the two or more pods can be performed such that the pods provide an even distribution of electrical power to the vehicle. In other words, each pod is activated to pro vide the same amount of electrical power to the vehicle.

The electrical and commu nication connectivity unit can refer to electrical signal wires, to electrical power wires, to means of connecting with avionics, to Controller Area Network (CAN) communication chan nels, or to command and control channels being connected to the centralized energy management unit 18.
The distributed energy nacelle modules 15 can be utilized in different ways depending on the size/airframe of the aircraft. Certain large electrical aircraft would require the use of multiple energy nacelle modules 15 being arranged in parallel and other smaller aircraft may only need a single system.
Hence, the nature/size of the aircraft plays a major role in determining the power output specifications for each of the distributed energy nacelle modules 15 and the followings are only examples for this disclosure, though this disclosure is not limited to the power and energy values provided below.
In one implementation, the energy nacelle module 15 is adapted to provide a predetermined power (W) and energy (Wh) combina tion each in the following range: configurations are fixed within a nominal power range from 0.1 watts (W) to 1000 kilo watts (kW) of nominal power, and from 1 watt-hour (Wh) to 10,000 kilowatt-hours (kWh) of stored energy.
In use, the multiple energy nacelle modules 15 serve to power and to move the aircraft 10.
The centralized energy management unit 18 provides an even en ergy distribution of energy supply by the different energy na celle modules 15, wherein the aircraft 10 can function stably even if one or more energy nacelle modules 15 fail.
In detail, the centralized energy management unit 18 sends in structions to the different energy nacelle modules 15 for ac tivating the respective energy nacelle modules 15.
The embedded processor of each electronics module 33 receives the instructions from the centralized energy management unit 18. The embedded processor then sends corresponding instructions to the power generation module 25 for activating the power generation module 25.
The activated power generation module 25 later provides elec trical energy to the propulsion module 27.
In particular, the electronics module 33 can activate the en ergy storage module 25-2 of the power generation module 25 to provide hydrogen gas to the fuel cell stack 25-1, wherein the fuel cell stack 25-1 uses the hydrogen gas to generate elec trical energy and transmits the electrical energy to the elec tric motor 27-1 of the propulsion module 27.
The electronics module 33 can also activate the battery pack 25-3 to provide electrical energy to the electric motor 27-1 of the propulsion module 27.
The energised electric motor 27-1 then provides mechanical en ergy to turn the propeller 27-2 for moving the aircraft 10.
The centralized energy management unit 18 is also adapted to provide safety through active system health management. Put differently, the centralized energy management unit 18 is adapted to ensure safe and continuous power supply with redun dant, automated and controlled distribution, and adapted to resolve emergency conditions. The centralized energy manage ment unit 18 controls and manages energy from different energy sources of the power generation module 25. These energy sources can include solar panels. As an example, the central ized energy management unit 18 activates an energy system of one energy nacelle module 15 to provide power to a propeller and a motor of an aircraft. In a case of an issue with the en ergy system, the centralized energy management unit 18 can then activate a second energy system of another energy nacelle module 15 to provide power to the propeller and the motor.
In a special embodiment, the energy nacelle module 15 is adapted for connecting to additional external power sources, such as solar.
The embodiment provides a network of distributed electric en ergy sources that provides an enhanced distributed energy ar chitecture for an aircraft or an unmanned aerial vehicle (UAV) . The energy nacelle modules 15 can be distributed or placed on top or beneath wings of the aircraft or the UAV. The number and configurations of the energy nacelle modules 15 can be chosen based on specific requirements of the aircraft or the UAV.
The embodiment also provides a network of interchangeable dis tributed external hydrogen fuel cell/battery hybrid electrical energy systems containment pods that enables smart and effi cient power generation architectures for different aircraft or unmanned aerial vehicles platforms, which in return yields an improved aircraft concept. The fuel cell/battery hybrid based distributed electric energy pods can be utilized as multiple systems in parallel that is multiple pods operated in paral lel, or as a single powering system to move and power an elec trically powered aircraft, or as a single system to move and power an unmanned aerial vehicle.
In a general sense, the energy nacelle module 15 can be con figured for adding to existing or future aircraft fuselage to serve as an electric energy range extender unit.
