[0011] Aspects of the devices, systems and methods disclosed include methods for aggregating data relating to power consuming devices including connecting a plurality of charging device for delivering power to a plurality of portable power-consuming devices sensing, by a profile sensor in each charging device, information relating to the identity of the power-consuming device; sensing, by a profile sensor in each charging device, operational data of the power-consuming device; andtransmitting said information to a remote server over a communication channel.

[0012] operational data , in some instances is at least one of the date and / or time of each charging event, the voltage and / or current profile or 'signature' of each charging event, the geographical location of each charging event, and the condition of the charging device 1 at, before, during or after each charging event. In some instances the aggregated data is used to predict performance of power consuming device is in a variety of conditions.

[0013] Persons of ordinary skill in the art of computer programming will recognize that the disclosure herein references operations that are performed by a computer system. Operations which are sometimes referred to as being computer-executed. It will be appreciated that such operations are symbolically represented to include the

manipulation by a processor, such as a CPU, with electrical signals representing data bits and the maintenance of data bits at memory locations, such as in system memory, as well as other processing of signals. Memory locations wherein data bits are maintained are physical locations that have particular electrical, magnetic, optical, or organic properties corresponding to the data bits.

[0014] When implemented in software, elements disclosed herein are aspects of some of the code segments to perform necessary tasks. The code segments can be stored in a non-transitory processor readable medium, which may include any medium that can store information. Examples of the non-transitory processor readable mediums include an electronic circuit, a semiconductor memory device, a read-only memory (ROM), a flash memory or other non-volatile memory, an optical disk, a hard disk, etc. The term "module" may refer to a software-only implementation, a hardware-only implementation, or any combination thereof. Moreover, the term "servers" may both refer to the physical servers on which an application may be executed in whole or in part. The regular or periodic connection of a charging device to one or more power-consuming devices offers a useful mechanism by which to gather data from the power-consuming devices to which the charging device is connected, and to transmit that data to a central resource via a communication network. With reference to Figure 1 , a charging device 1 is periodically connected to a power-consuming device 2 by way of a detachable or otherwise disconnectable charging and data link 3. The charging device 1 is connected, via a data link 7 and data communication network 4, to a server 5 having a database 6.

[0015] The charging device 1 may comprise any device capable of supplying power to a portable power-consuming device 2 in sufficient quantity to facilitate recharging, or at least partial recharging, of a battery or other charge storage device in the power- consuming device 2, or for powering the power-consuming device for extended periods of normal operation when auxiliary power is available. The expression 'charging device' may therefore encompass devices commonly referred to as power adaptors. The expression 'recharging' is intended to encompass any form of providing electrical energy to a storage device capable of storing energy for later release and may include regeneration of device in which chemical reaction takes place. In some instances the device 1 is a fuel cell power source, e.g. a hydrogen-powered proton exchange membrane fuel cell system capable of generating electrical power for recharging a power-consuming device 2 or for generally providing auxiliary power thereto. In other instances the charging device 1 could be a mains power adaptor for converting the domestic mains or line voltage from a high voltage alternating current to a low voltage direct current suitable for recharging or powering the power-consuming device 2. The charging device 1 could comprise a DC-DC voltage converter for use in, for example, a vehicle taking its input from a 12 or 24V vehicle electrical system and providing a low voltage direct current suitable for recharging or powering the power-consuming device 2.

[0016] The power-consuming device 2 may comprise any portable, self-contained and/or autonomous device which relies on an internal, rechargeable power source for operation which must be periodically recharged. Particular examples of such power- consuming devices include: mobile telephones including so-called 'smart phones';

personal computing devices including notebook computers, netbooks, tablet computers, personal digital assistants, etc.; entertainment devices such as music players, game playing devices or consoles; electronic books or 'e-readers'; video players, etc.;

cameras or video recording devices; and many other items commonly referred to as consumer electronics.

[0017] The charging device has a permanent or an intermittent data link 7 to a data communication network 4. The data communication network 4 may be the Internet or a local area network, for example. The data link 7 may be a wired connection or a wireless connection, using any suitable technology and transport protocol. For example, a short range wireless connection to a local WiFi router may be used for data link 7. Alternatively, a power connection 8 (shown as a dashed line) to a utility power line 9 could be used for data transfer to a router connected to the utility power line and to the network 4. In another arrangement (shown in Figure 2), the power-consuming device 2 itself may provide the data link between the charging device 1 and the network 4. This arrangement is shown in Figure 2 as link 7a (i.e. the charging and data link 3) and a communication channel 7b between the power-consuming device 2 and the network 4. In such an arrangement, the direct link 7 between the charging device 1 and the communication network 4 could be omitted. In other instances, the data link may be separate from the charging link. In yet other instances, the data may be transmitted back via the mains (or other low voltage network, for example, a telephone network), Ethernet, or other low voltage wired systems.

[0018] In a particularly convenient arrangement, where the power-consuming device 2 is a mobile telephone, the link 7a may comprise a USB cable and the communication channel 7b may comprise a cellular telephone network. In such an arrangement, communication between the charging device 1 and the network 4 and server 5 can conveniently be controlled by an application program loaded onto the power-consuming device 2 (e.g. smart phone).

[0019] The data link 7a could be the combined charging and data link 3 itself (e.g. USB cable), or the data link 7a could be separate from the hardwired charging link 3. In this respect, the data link 7a could be a short range wireless communication channel such as Bluetooth.

[0020] The server 5 may be any suitable remote computing resource including a database 6 which is capable of receiving data relating to the relationship between the charging device 1 and the power-consuming device 2 as will be explained in more detail below. The server 5 is preferably capable of managing data received from many such charging devices 1 , the data relating to relationships between the many such charging devices 1 and the power consuming devices to which they are periodically connected. The server 5 may be capable of aggregating data from these many relationships and providing the data to other entities such as one or more service providers 10. [0021] The charging device 1 includes a profile sensor 1 1 which may be configured to collect environment data relating geolocation, altitude, pressure, temperature, humidity. Some of said data can be collected via local sensors, other dat may be collected or approximated via a weather database and the rules and decision engines within the server correlate such data. Those of ordinary skill in the art will recognize that such data may be important in system with batteries and fuel cell components as they performance characteristics will vary based on variations in same. In addition to the environment data the system will also collect the identity of some or all of the power- consuming devices 2 to which the charging device 1 is connected for charging or power supply. The data can be stored or buffered in an internal data log 12. The data can be transferred either in real time, or in periodic bursts, to the server 5 at suitable times consistent with the availability of the data link 7 or 7a, 7b.

[0022] The data can be technically and/or commercially useful to: (i) manufacturers and/or vendors of the power-consuming devices 2, (ii) manufacturers and/or vendors of the charging devices 1 ; and, (iii) vendors of consumer services and products associated with the power-consuming devices 2 and /or the charging devices 1.

[0023] For example, the service provider 10 could be a manufacturer or vendor of power-consuming devices 2, or a service provider connected with the use of such power-consuming devices 2, e.g. mobile telephones. The charging device 1 may provide useful information relating to the performance of the charging process, indicative of the technical performance of the battery or power management system of the power-consuming device, its identity and its patterns or mode of use. In another example, the service provider 10 could be a manufacturer or vendor of charging devices 1 , or a service provider connected with the use of such power-consuming devices 1 , e.g. a fuel cell power supply manufacturer. The charging device 1 may then provide the service provider 10 with useful information relating to the performance of the charging process as it relates to different types of power-consuming device, and to different modes of use.

By way of example, the data gathered by the charging device 1 may include any or all of the following types of data: (i) a unique identifier, e.g. the individual identity or serial number of any power-consuming device 2 that has been connected to the charging device 1 ; (ii) a generic type identifier, e.g. the device type or class of device any power- consuming device 2 that has been connected to the charging device 1 ; (iii) a

manufacturer identity, e.g. the identity of the manufacturer of any power-consuming device 2 that has been connected to the charging device 1 ; (iv) the date and/or time of each charging event; (v) the voltage and/or current profile or 'signature' of each charging event, e.g. a current-time profile, a voltage-time profile, a voltage-current profile, a charge state-time profile, which may be derived over time from a separate database which can match the profile of what is measured through the intelligence of the charging device comparing with other database records to match or approximate what the device is in the event that the device cannot be detected then and there by asking it "what it is" with a query from the charger to the device for instance; (vi) the geographical location of each charging event, which could be automatically sensed either by the charging device 1 or the power-consuming device 2, e.g. using GPS sensing, collected environment data, network address sensing or a combination thereof; (vii) the condition of the charging device 1 at, before, during or after each charging event (e.g. for a hydrogen fuel cell, the hydrogen level remaining or fuel cell

performance parameter); (viii) a usage profile of the power-consuming device 2 or the charging device 1 , e.g. time and frequency of use, power demand, modes of use etc.

[0024] The above list is not intended to be exhaustive but provides examples of information relating to the identity of the power-consuming device to which the charging device is connected.

[0025] Such information can be usefully deployed for a wide range of purposes.

[0026] The data can be used to authorize use of the charger 1 for a particular charging event (e.g. to prevent unauthorized or inappropriate use that could damage either the charger 1 or power-consuming device 2). Environment data may be provided to at least one of the device, charger and the server wherein system parameters and data may be correlated to the environment data.

[0027] The data can be used to control a mode of use of the charger, e.g. by ensuring use of a particular charging mode or operational profile of the charging device for each power-consuming device 2 to which it is connected to prevent damage to either device. Examples of a charging mode or operational profile could include determining maximum current or voltage as a function of time and/or existing charge state or voltage, or could include limiting current for some or all of a charging event.

[0028] The data can be used to provide information on the technical performance of either the charging device 1 or the power-consuming device 2 under varying conditions of use, including frequency of charging, location of charging, and conditions prevailing during charging. Such conditions could include local conditions of temperature or humidity or air pressure, for example. Environment data, as previously noted, may be derived locally, or acquired from remote locations (i.e. weather websites).

[0029] Such technical data may be useful in assessing the performance of devices over many hundreds or thousands of power-consuming devices in widely varying conditions of use. Such data when aggregated for particular types of power-consuming device, over many thousands or millions of charging events, can be used to very accurately identify problems with the technical design of the power-consuming device or te charging device, or with different users' modes of use of the devices. This can direct product improvement either to the existing devices or to future devices. The data could direct product improvement to existing devices by facilitating the re-design and download of, for example, software upgrades to either the charger 1 or the power- consuming device. The software could control power management in the devices.

[0030] The data may be used to indicate when device servicing or replacement is required, or to optimize service plans of the devices, including indicating when a fuel source (e.g. hydrogen source) for a charging device may need replenishment. The data may be used to manage such servicing, e.g. by enabling a service provider to indicate directly to the user how and where to effect such servicing, based on the gathered data. The data may be used to collect data on user choice of devices and such data may predict trends of use. The data may also track brand (device such as cell phone) to market dominance as well as success or decline in a brand.

[0031] Where the power-consuming device 2 has on-board intelligence, such as a data processing capability and/or data communication facility (e.g. USB connectivity), the charging device 1 may be able to interrogate the power-consuming device 2 to supply at least some if not all the required data directly, using a suitable data exchange protocol for connectivity of the charging device and the power-consuming device. This could be supported by USB protocols, for example.

[0032] In other arrangements, the charging device 1 may be configured to deduce some or all of the required data itself by monitoring an observable characteristic of the power-consuming device during operation or charging, such as the voltage and/or current profile as a function of time or 'signature' of the charging process. By collecting detailed information on charging per user, per location and per device(s) energy (or utility) packages may be narrowly tailored for the needs of the user.

[0033] As demanded by the power-consuming device during the charging or power supply event, the charging device 1 may be able to deduce an identity of, or a device type of, the connected power-consuming device 2 by comparing a voltage and/or current profile or signature with a set of templates each of which indicates a particular device type or device identity. The templates could be stored at a suitable location such as within the charging device 1 or at the remote server 5. The identities of the power- consuming devices 2 that are connected to the charging device 1 can therefore be determined either by the charging device, or by the server 5, or partially in both the charging device and server 5, for example.

[0034] In general, the data can be aggregated, analyzed and/or buffered either on the charging device 1 itself in the data log 12 for periodic upload to the central server 5 or can be transmitted unprocessed or partially processed and/or in real time to the central server 5, depending on the availability of a data communication link 7 or 7a, 7b.

[0035] The charging device 1 could be supplied to end users together with an application program for use on the power-consuming device 2 (e.g. mobile telephone, portable computer) which controls or monitors operation of the charging device 1 , particularly where this is a fuel cell charging device requiring sophisticated management for optimal performance. The application program then also serves as a suitable conduit, via communication channels 7a, 7b, for the data gathered by the charging device 1. The application program can readily be configured and authorized to use the telecommunication data channel 7b of a mobile phone, in order to transfer data to the server 5 over the communication network 4. In such a case, the communication network 4 can be a combination of the cellular telephone network and the Internet. The application program can also provide any required credentials required for access to the server 5.

[0036] In a general aspect, reference to the communication channels 7, 7a may include the transmit/receive components in each of the charging device 1 or power consuming device 2 as appropriate at the device level, and the data connections between them at the overall system level. Thus, in the context of a charging device 1 , the expression 'communication channel' can be understood to refer to the transmit and receive and interface components and connectors within the device necessary to achieve a communication with the network 4 or power consuming device 2. In the context of the overall system level, the expression 'communication channel' can be understood to refer to all elements in the communication chain between the charging device and the server 5.

It should be understood that this disclosure is intended to yield a patent covering numerous aspects of the disclosure both independently and as an overall system and in both method and apparatus modes.

[0040] Further, each of the various elements of the disclosure and claims may also be achieved in a variety of manners. This disclosure should be understood to encompass each such variation, be it a variation of an implementation of any apparatus

implementation, a method or process implementation, or even merely a variation of any element of these.

[0041] Particularly, it should be understood that as the disclosure relates to elements of the disclosure, the words for each element may be expressed by equivalent apparatus terms or method terms - even if only the function or result is the same.

[0042] Such equivalent, broader, or even more generic terms should be considered to be encompassed in the description of each element or action. Such terms can be substituted where desired to make explicit the implicitly broad coverage to which this disclosure is entitled.

[0043] It should be understood that all actions may be expressed as a means for taking that action or as an element which causes that action.

[0044] Similarly, each physical element disclosed should be understood to encompass a disclosure of the action which that physical element facilitates.
