Description
TITLE - Improvements related to Battery-Powered Electronic Devices
The present invention relates to battery-powered electronic devices.
Many electronic devices, particularly portable electronic devices, incorporate rechargeable batteries which allow the device to be used for a limited period of time before the battery needs to be recharged. An example of such a device is an RFID reader, which is used to read information from RFID tags.
Commonly used rechargeable batteries include lithium ion batteries, which have a high energy density and low-self discharge. Although lithium ion batteries are popular for these reasons, lithium ion batteries are classified as dangerous goods in view of the pressurised flammable electrolyte contained therein. There are therefore strict regulations in place for the transport, for example by air, of lithium ion batteries, as well as electronic devices which contain lithium ion batteries. In particular, restrictions are in place which set an upper limit on the level of charge stored by a lithium ion battery to allow the battery to be transported.
There has now been devised an electronic device, and a method of discharging a battery of an electronic device, which overcome or substantially mitigate the aforementioned and/or other disadvantages associated with the prior art.
According to a first aspect of the present invention there is provided an electronic device comprising a battery and a controller having a mode in which the controller: a) receives at least one input command b) determines whether the at least one input command matches a predetermined discharge command, and c) causes operation of the electronic device to discharge the battery to a predetermined charge level where the at least one input command matches the pre-determined discharge command.
According to a second aspect of the present invention there is provided a method of discharging a battery of an electronic device, the method comprising providing a controller of the electronic device with at least one input command, and determining whether the at least one input command matches a pre-determined discharge command, such that the controller causes operation of the electronic device to discharge the battery to a pre-determined charge level where the at least one input command matches the pre-determined discharge command.
The device and method of the first and second aspects of the present invention may be beneficial principally as the controller of the electronic device has a mode in which the controller causes operation of the electronic device to discharge the battery to a pre-determined charge level where at least one input command matches a pre-determined discharge command. In particular, this dedicated mode may discharge the battery to an appropriate pre-determined charge level, without the need for further user input other than the initial input command. This may remove the need for the device to be monitored during discharge of the battery, thereby saving both time and labour costs.
Furthermore, the dedicated mode may allow automatic discharge of the battery of an electronic device in response to an input command, until the level of charge in the battery reaches a pre-determined level. This may simplify the procedure necessary to place an electronic device in a condition suitable for transport by air.
The mode in which the controller receives at least one input command, determines whether the at least one input command matches a pre-determined discharge command, and causes operation of the electronic device to discharge the battery to a pre-determined charge level where the at least one input command matches the pre-determined discharge command, may be referred to as a discharge mode. The discharge mode may differ from a normal mode of operation of the electronic device. For example, a normal mode of operation of the electronic device may be a mode in which the electronic device is operable to perform its intended function, whilst the discharge mode may be a mode in which the electronic device is operable to discharge its battery to a pre-determined charge level. The electronic device may not be operable in its discharge mode to perform its intended function, and may have increased power consumption relative to the normal mode of operation.
The pre-determined charge level may be less than, or equal to, 50%, 40%, 30%, 20%, or 10% of the total charge capacity of the battery. The pre-determined charge level may be greater than 0% of the total charge capacity of the battery.
The electronic device may comprise an electrical load, which consumes power.
The electrical load may be a resistive load, ie a resistor, and the controller may, for example, be configured to operate the electronic device to apply a voltage across the load in response to the at least one input command. Thus by applying a voltage across the load, the battery may be discharged to the pre-determined level.
The at least one input command may comprise an electronic signal derived from an authentication object or device. The at least one input command may comprise an electrical signal communicated through an electrical connection, eg a USB connection. Alternatively, the at least one input command may comprise an electronic signal derived from electromagnetic radiation. The at least one input command may comprise an electronic signal derived from any, or any combination, of radio waves, infra-red light, visible light, or ultra-violet light.
The electronic device may comprise a reader for reading an authentication object. The reader may comprise a source of electromagnetic radiation, and a sensor for sensing electromagnetic radiation emitted by the authentication object. The source of electromagnetic radiation may have a pre-determined frequency or range of frequencies, and electromagnetic radiation emitted by the authentication object may have a frequency that is similar to, or equal to, the frequency or range of frequencies of the electromagnetic radiation of the source.. The source of electromagnetic radiation may comprise a source of radio waves, infra-red light or visible light, for example. Similarly, the sensor may sense radio waves, infra-red light or visible light, for example.
The reader may comprise a camera, and the electronic device may comprise a processor configured to generate the at least one input command in response to an image and/or video of an authentication object captured by the camera.
The authentication object may comprise any or any combination of an RFID tag, a barcode, or a QR code.
The electronic device may comprise a user interface, and the at least one input command may be inputted by a user of the electronic device via the user interface. For example, the user interface may comprise a push-button or touch-screen interface, and the discharge mode may be selected by actuation of a push-button or a touch-screen.
The controller may be configured to operate the device in a normal mode of operation to discharge the battery to a pre-determined charge level in response to the at least one input command. For example, the controller may be configured to operate the electronic device to achieve the intended function of the electronic device, until the pre-determined charge level is reached. The controller may be configured to turn off the electronic device once the pre-determined level has been reached.
The controller may have a mode in which the controller receives a plurality of input commands, determines whether the plurality of input commands matches predetermined discharge commands, and causes operation of the electronic device to discharge the battery to a pre-determined charge level where the plurality of input commands match pre-determined discharge commands. The controller may have a mode in which each of the plurality of input commands must be received, and must match a plurality of pre-determined discharge commands, for the controller to cause operation of the electronic device to discharge the battery to the predetermined charge level. This may prevent accidental activation of the discharge mode of the electronic device.
The plurality of input commands may comprise input commands of differing formats including, for example, input commands of different type, duration, strength, etc. For example, the controller may have a mode in which the controller must receive an input command of a pre-determined form, for a pre-determined period of time, in order to cause operation of the electronic device to discharge the battery to the pre-determined charge level.
The plurality of input commands may comprise input commands derived from different authentication objects, or may, for example, comprise input commands derived from a single authentication object.
The battery may comprise a rechargeable battery, for example a lithium ion battery. The electronic device may comprise a portable electronic device, for example an RFID reader, or a mobile telephone.
The electronic device may comprise a monitor for monitoring the level of charge stored by the battery. The monitor may comprise a battery gas gauge. The monitor may be configured to monitor the level of charge contained in the battery continuously whilst the battery is discharging. The monitor may be configured to transmit battery charge level information to the controller.
The controller may comprise a microprocessor.
The method may comprise discharging the battery to a pre-determined charge level which is less than, or equal to, 50%, 40%, or 30%, of the total charge capacity of the battery.
The method may comprise applying a voltage across a load, eg a resistor, of the electronic device in response to the at least one input command. Thus by applying a voltage across the load, the battery may be discharged to the predetermined level.
The method may comprise reading an authentication object to generate the at least one input command. The method may comprise interrogating an authentication object with a source of electromagnetic radiation, and receiving a response in the form of electromagnetic radiation emitted by the authentication object, to generate the at least one input command.
The method may comprise interrogating an authentication object with a radio wave source, and receiving a response in the form of radio waves emitted by the authentication object, to generate the at least one input command. The electronic device may comprise an RFID reader, and the authentication object may comprise an RFID tag. The method may comprise scanning an RFID tag using an RFID reader, to generate the at least one input command.
The method may comprise interrogating an authentication object with an infra-red light source and/or a visible light source and/or an ultra violet light source, and receiving a response in the form of infra-red and/or visible and/or ultra violet light emitted by the authentication object, to generate the at least one input command. The electronic device may comprise a barcode and/or QR code scanner, and the authentication object may comprise a barcode and/or a QR code. The method may comprise scanning a barcode and/or a QR code using a barcode and/or QR code scanner, to generate the at least one input command.
The electronic device may comprise a camera, and a processor configured to generate the at least one input command in response to an image and/or video of an authentication object captured by the camera. The method may comprise using a camera of the electronic device to capture an image and/or video of an authentication image, and generating the at least one input command using the captured image and/or video.
The method may comprise providing a controller of the electronic device with a plurality of input commands, such that the controller causes operation of the electronic device to discharge the battery to a pre-determined charge level where the plurality of input commands match pre-determined discharge commands.
The method may comprise providing a controller of the electronic device with input commands of differing formats including, for example, input commands of different type, duration, strength, etc.
According to a third aspect of the present invention there is provided a data carrier comprising machine readable instructions for a controller of an electronic device, the electronic device comprising a battery, and a controller having a discharge mode, wherein the instructions cause operation of the controller to: a) receive at least one input command b) determine whether the at least one input command matches a predetermined discharge command, and c) cause operation of the electronic device to discharge the battery to a predetermined charge level where the at least one input command matches a pre-determined discharge command.
Preferential features of each aspect of the present invention may be applied equally to other aspects of the present invention, where appropriate.
Practicable embodiments of the invention will be described in further detail below with reference to the accompanying drawings, of which:
Figure 1 is a schematic diagram of an electronic device according to the first aspect of the present invention; and
Figure 2 is a schematic diagram illustrating a method of discharging a battery of an electronic device according to the second aspect of the present invention.
An electronic device according to the first aspect of the present invention, generally designated 10, is shown schematically in Figure 1. The device 10 as shown in Figure 1 is an RFID reader 10.
The RFID reader 10 comprises a microcontroller 12, a battery 14, a gas gauge 16, and a UHF transponder 18. The microcontroller 12, battery 14, gas gauge 16, and UFIF transponder 18 are conventional components which may typically be found in a conventional RFID reader. The microcontroller 12 is configured to receive information from both the gas gauge 16 and the UHF transponder 18, and is further configured to operate as will be described in more detail below, and with reference to Figure 2.
The RFID reader 10 is used to read 22 an RFID tag (which is a further UHF transponder) 20. The microcontroller 12 determines 24 whether the RFID tag 20 is a tag configured to send the microcontroller 12 into a discharge mode. If the RFID tag 20 is not a tag configured to send the microcontroller 12 into a discharge mode, then the RFID reader 10 performs its normal function 26 having regard to the RFID tag 20.
If the RFID tag 20 is a tag configured to send the microcontroller 12 into a discharge mode, then the microcontroller 12 configures 28 the RFID reader 10 to discharge the battery 14 by placing a load across a resistor (not shown). During discharge, the level of charge in the battery 14 is read by the gas gauge 16, and this information is fed to the microcontroller 12. The microcontroller 12 thus determines 31 the level of charge in the battery 14. If the level of charge in the battery is above a pre-determined threshold, in the present case 30%, then the microcontroller continues 32 to operate the discharge mode. If the level of charge in the battery is below a pre-determined threshold, in the present case 30%, then the microcontroller interrupts 34 the discharge mode, and shuts down 36 the RFID reader 10.
