Description

Charging system for charging storage battery device in electronic equipment, and charging equipment and electronic equipment used in the system

technical field

The present invention relates to a charging system, and also to an electronic device and a charging device for the charging system.

Background technique

Electronic equipment with rechargeable batteries, whether portable measuring equipment, wireless computer keyboards, wireless mice, mobile terminals, simple electric batteries, or any other type of equipment, has means to attach and connect a charger for the battery. Therefore, the required charger is usually of a specific type or style, and is often provided to the user along with the electronic device.

In many cases, there is a need for more flexibility in choosing a charger for a device. For example, a user is unlikely to carry the charger that powers him with the device, and they may plan to bring another type or style of charger with the device, not knowing whether that charger's specifications apply to The need for the device to be charged.

On the other hand, there may be a need to be more selective in choosing a charger for a device in other situations. For example, a manufacturer of an electronic device may only require a certain type, model, or style of charger for use with that electronic device and not use others.

Certain electronic devices with rechargeable accumulators are adapted to be attached and connected to an external electronic unit, such as a PC, for data exchange between the electronic device and the external electronic unit. Consequently, the device has to be provided with a separate connector for attaching an external electronic unit, in addition to the connector provided for the charger for the battery. In mass production, including two separate connectors would require additional parts and materials, be time consuming, and thus increase cost.

Contents of the invention

It is an object of the present invention to provide greater flexibility for connecting electronic equipment comprising electric accumulators to a charger.

Another object of the present invention is to provide more options for connecting electronic equipment including electric accumulators to a charger.

These objects are achieved by means of a charging system comprising an electronic device and a charging device, the electronic device being adapted to be connected to the charging device for charging a storage battery device in the electronic device, thereby according to the Communication protocol for connection, the charging device is suitable for transmitting and the electronic device is suitable for receiving at least one signal, and/or the electronic device is suitable for transmitting and the charging device is suitable for receiving at least one signal, and in addition, the electronic device is suitable for connecting to an external electronic device unit such that according to the communication protocol the external electronic unit is adapted to transmit and the electronic device is adapted to receive at least one signal and/or the electronic device is adapted to transmit and the external electronic unit is adapted to receive at least one signal.

Thus, based on the physical attachment of the charging device to the electronics, specific properties of the structure can be established for the charging of the accumulator, or charging can be suspended if certain undesirable properties occur in the structure. Established performance may include maximizing charging power or current. Furthermore, the communication protocol can be used to determine whether the electronic device is connected to a charging device or an external electronic unit. Based on this determination, the connection structure can be configured for the transfer of power or for the exchange of data depending on the combination at hand, whether it is a charger-device combination or some other combination. In other words, when the charging device and the electronic device are connected, the communication protocol can be used to establish these capabilities, and based on this establishment, the electronic device can be constructed so that the storage battery device receives charging power from the charger in as efficient a manner as possible. . As a result, a charging device or some external electronic unit can be connected to the electronic device using the same connector behind. Usually, a more flexible system is provided with the electronics to be connected to the charger as well as the external electronics unit. This embodiment also simplifies the design of the electronic device by allowing one connector on the electronic device to be used for charging and other applications, reducing production time and materials required for production, thus reducing the production cost of the device.

Preferably, the communication protocol specifies at least one mechanical property of at least one connector for connecting the electronic device and the charging device, at least one electrical property of the electronic device interface and/or the charging device interface, and command settings used by the charging device, with to enumerate (identify) electronic devices. This provides a lot of flexibility or choice in the combination of devices and chargers. For example, the present invention may be used to allow charging of a battery device by a particular model or make or charger having specifically specified charging characteristics, such as a charging current.

Preferably, at least one application data set according to the communication protocol is stored in at least one electronic memory provided in the electronic device, the at least one application data set comprising data requested according to the communication protocol for charging the accumulator device with the charging device. Thus, the electronic device can be easily adapted for connection to a selected charger or other type through appropriate access in the electronic memory. For example, by augmenting the application data set, the device may be adapted to be connected to a charger that has a different specification than other chargers to which the device is suitable to be connected. The application data sets requested for charging the accumulator device can be arranged in the electronic memory of the device in any desired manner, for example by relevant entries. It is also possible to arrange at least two subsets of data distributed to different registers or to the same memory or memories so that the subsets are connected using subscripts or pointers.

Preferably, at least one application data set comprises a structured data set, whereby the charging device is adapted to send at least one signal to the electronic device for retrieving at least one structured data set or at least one of the charger's structured data set from the at least one electronic memory. subset of . Thus, the system has an efficient way to establish and implement a proper structure for charging the accumulator device.

Preferably, at least one of the application data sets includes at least one power delivery scheme for delivering power from an external electronic unit or a charging device to the electronic device. Thus, the power delivery is adapted to the needs of the electronic device when connected to the external electronic unit, and re-adapted to the needs of the electronic device when connected to the charging device. In the latter case, the need is often very different from the former. For example, if the external electronic unit is a PC, power may be delivered to the electronic device corresponding to various functions of the electronic device, but there may be a need due to limitations in the power delivery capability of the external electronic unit. This need may change when equipment and units are connected. Therefore, the power delivery scheme for the connection may allow the delivered power to be varied according to the charging needs. When the charger is connected to the electronic device, an alternative power delivery scheme is provided so that optimal charging power for the battery device can be ensured.

These objects of the invention are also achieved by an electronic device according to claims 14-16 and a charging device according to claims 17-24.

Description of drawings

Further advantages of the invention will be disclosed below, wherein the invention will be described in more detail with the help of the accompanying drawings, in which Figures 1 and 2 are block diagrams illustrating a system according to an embodiment of the invention.

Detailed ways

The block diagram of FIG. 1 schematically shows an electronic device 1 . The electronic device 1 comprises accumulator means in the form of one or more rechargeable batteries or accumulators. The electronic device 1 may be adapted to perform any of a number of functions related to computer applications, telecommunications or other various types of information technology whereby power from the battery means may be used to perform these functions. For example, it may be a portable measuring device, a wireless manual input device such as a wireless computer keyboard or a wireless mouse, or a mobile terminal.

The electronic device 1 includes a connector 3 for connecting an external electronic unit 4a, for example via a cord. For example, the external electronic unit 4a may be a personal computer (PC). Using the computing and storage capabilities in the electronic device 1 and the external electronic unit 4a described in more detail below, the connection via the connector 3, and according to the communication protocol that constitutes the connection between the electronic device 1 and the external electronic unit 4a, the external electronic unit 4a is adapted to transmit and the electronic device is adapted to receive at least one signal, and/or the electronic device is adapted to transmit and the external electronic unit 4a is adapted to receive at least one signal. The communication protocol can specify the mechanical properties of the electronic device 1 (including the connector 3 ) and the connectors in the external electronic unit 4a, the electrical properties of the electronic device interface and the interface of the external electronic unit 4a, and the frame format. The protocol can also specify the command set used by the external electronic device to enumerate (identify) the electronic device 1 and determine whether there are sufficient resources in the external electronic unit 4a, such as bandwidth and power, to accept the electronic device 1. This provides the attachment to the external electronic unit via the connector 3 making up the connection by means of a communication protocol and thereafter utilizing a connection for data transfer between the electronic device 1 and the external electronic unit for any application Such as an electronic device 1 on a PC.

The communication protocol may be USB specified by the Universal Serial Bus Specification. USB is a standard specifying a packet oriented communication protocol for simultaneously connecting a large number of devices, such as printers, modems, and keyboards, to a host computer, such as a PC. Generally as mentioned above, the USB standard specifies the mechanical properties of the device and host cable connectors, the electrical properties of the device and host interface, the frame format, and the command settings used by the host to enumerate (identify) the device and determine the bus Whether there are enough resources on the bus, such as bandwidth and power, to accept the device on the bus.

Referring to Fig. 2, according to the invention, the electronic equipment is adapted to be connected, for example via a cord, to a charging device 4b for charging the accumulator means 2 in the electronic equipment. Thus, the charging device 4 b is connected to the electronic device 1 using the same connector 3 that follows when the external electronic unit 4 a is connected to the electronic device 1 . The charging device 4b is configured with computing and data storage functions represented by the processing and storage means 4c. The processing and storage means 4c of the charging device can communicate with the electronic device 1 via a suitable connector 4d and bus. Thus, according to the communication protocol, the charging device 4b is suitable for transmitting and the electronic device 1 is suitable for receiving at least one signal, and/or the electronic device 1 is suitable for transmitting and the charging device 4b is suitable for receiving at least one signal.

Preferably, the communication protocol is specified by the USB standard. According to this, four wires are utilized to carry power and signals between the charging device 4b and the electronic device 1: Vbus5, which provides power, ground 6, which provides a power and signal return path, D+ and D-, which together act as a differential half-duplex signal pair. In the initial connection detection phase of the electronic protocol, D+ and D- are used by the external electronic unit 4a (see FIG. 1 ) or the charging device 4b (see FIG. 2 ) to detect the presence of the device 1 . D+ and D− are used by the external electronic unit 4a or the charging device 4b to detect the working speed of the electronic device 1 .

Of course, the means for transmitting power and signals may be represented in any alternative suitable form within the scope of the present invention, for example employing an alternative number of conductors.

In the preferred specification of the USB standard, the host is usually the power source and the device is usually the power sink. When USB is used in the present invention, according to the USB nomenclature, both the charging device and the external electronic unit, such as a PC, are regarded as hosts, and what is referred to as an electronic device herein is simply referred to in the USB nomenclature as as "device".

The electronic device 1 has at least one data processor 7 connected to the connector 3 and accesses at least one electronic memory 8 . The data processor 7 is a CPU, but alternatively it can be any processing unit implementing a communication protocol. In the memory 8 at least two application data sets 9, 10 according to the communication protocol are stored. Each application data set 9 , 10 includes a structure data set 91 , 101 . At least one of the application data sets 9, 10 is a unit application data set 9, including a unit structure data set 91, and at least one of the application data sets 9, 10 is a charger application data set 10, including a charger structure data set 101 . In the following, the structured data set is also referred to simply as a structure. In this article, only two application data sets and two structures are mentioned, but the memory can store a large number of application data sets and structures. Each structure 91, 101 includes a structure descriptor 9a, 10a, at least one interface descriptor 9b, 10b and any number of endpoint and function descriptors (not shown in the figure), each describing protocol parameters for the electronic device 1 some of the functions. Associated with each structure 91, 101 is a string descriptor 9c, 10c. The index in each structure descriptor 9a, 10a points to a string descriptor 9c, 10c, which is used to identify the respective structure descriptor 9a, 10a. For this representation, the structure descriptor 9 a , 10 a and the interface descriptor 9 b , 10 b are also referred to as subsets of the respective structure 91 , 101 . Furthermore, for this representation, the structures 91 , 101 , the structure descriptors 9 a , 10 a , the interface descriptors 9 b , 10 b and the string descriptors 9 c , 10 c are also referred to as subsets of the respective application data sets 9 , 10 .

The cell structure 9 includes a cell structure descriptor 9a, which includes an index to a cell string descriptor 9c. It should be noted that, as an option, the cell structure 9 may appear without the string descriptor 9c. In the latter case, the index in the structure descriptor can indicate the presence of a string descriptor, for example by reading "0". The unit structure 9 includes data requested according to a communication protocol for establishing a connection between the external electronic unit 4a and the electronic device 1 . In more detail, the interface descriptors in the structure determine the functions provided to the units or devices connected to the electronic device 1 . For example, an interface descriptor may contain communication parameters for a hand input device (HID).

Referring to FIG. 2, a charger structure 101 includes at least one interface descriptor 10b for charger functions, and a charger structure descriptor 10a including an index of a charger string descriptor 10c. The charger string descriptor 10c has a unique value, preferably a GUID (Unique ID in the world). The charger structure descriptor 10a and the interface descriptor 10b include data requested according to a communication protocol for connecting the charging device 4b and the electronic device 1 . Preferably, the interface descriptor 10b specifies a charger-specific protocol, and it takes at least terminal zero, since it is mandatory in all USB devices. The charger structure 101 may also include at least one charger protocol-specific function descriptor, which describes options in the charger protocol supported by the specific electronic device 1 . These options may include limits for power delivery, eg, higher limits than the 500mA limit in the USB specification. In the case of the USB standard, in order to exceed 500mA, the charger should be attached directly to the electronic device, ie without an intervening "hub".

Preferably, the charging device 4b has a command setup so that it is set to run the enumeration process so that it sends and receives signals to and from the device 1 so that the charger structure 101 is retrieved. Thus, the charging device sends the index from the processing and storage means 4c of the charging device 4b for retrieving the structure 91 , 101 corresponding to the index. The electronic device 1 then sends the structure corresponding to this index to the charging device, whereby the charging device retrieves the respective associated string descriptors 9c, 10c obtained in the same way. The string descriptor is compared with the search word 4e stored in the processing and storage means 4c of the charging device, and when the string descriptor matches the search word 4e, the charging device 4b sends a signal to the device 1, while the index is used for searching and matching The associated string descriptor matches the structure used to set or implement the structure corresponding to this index.

As an alternative enumeration process, the charging device 4b sends the search word 4e corresponding to the string descriptor 10c of the charger application data set 10 to the electronic device 1, so that the electronic device 1 sets or realizes the charger structure 101.

Preferably, prior to setting the structure, it is determined whether the power request in the structure is within the limits of the charger. If within the limit values, the charging device can select this configuration and the electronic device 1 can start charging its battery pack 2 . Otherwise, all processing on the bus is stopped, so that the electronic device 1 can turn off its interface and minimize its power consumption. In the latter case, if a charging indicator or other charging process display is provided, the indicator or other display may be turned off or indicate a non-charging state.

It should be noted that the system according to the invention can be modified so that the charger can accept various configurations stored in the memory of the electronic device. In other words, upon reading these structures or subsets thereof, any number of these structures or subsets thereof employed in the charging process can be identified.

Preferably, the structure descriptors are read according to a selected numbering order of the descriptors. Preferably, if the communication protocol is specified by the USB standard, the charger structure descriptor or descriptors should not have a minimum number, because the external electronic unit can be formed according to the naming rules herein. Some larger operating systems automatically choose the first read of the structure descriptor, ie choose the one with the lowest number.

Each structure descriptor 9a, 9b includes a power delivery scheme 9d, 1Od for delivering power from the external electronic unit 4a or the charging device 4b to the electronic device. Thus, as explained above, the power supply can be arranged in different ways according to different needs determined by the kind of unit or device to which the electronic device 1 is connected, i.e. the power requirements can be adapted to have the external electronic unit 4a or the charging Structure of device 4b. Of course, each power transfer scheme 9b, 10d could alternatively be arranged in the respective application data set, eg distributed to a separate subset of the respective application data set.

It should be noted that the application data sets 9, 10 may be arranged in any suitable alternative with or without string descriptors 9c, 10c for identifying the application data sets or structures. For example, each interface descriptor 9b, 10b in the structure 91, 101 may retrieve some unique value or code identifying a function for connecting a charging device to the device. Accordingly, coding of functions may be selected and implemented in any suitable manner. In each structure, these functions can be set according to the list. In the case where the communication protocol is specified by the USB standard, the interface descriptors 9b, 10b can be identified by interface class, interface subclass and interface protocol. In other words, all structures for interface descriptors specifying a particular classification and protocol encoding can be scanned. However, since it is a 24-bit value, this is a less reliable solution as the classification and protocol encoding may already be adopted by some pre-existing products. Alternatively, in any suitable communication protocol, the application data set or structure may identify the employed data by assigning the application data set itself or one or more portions of the structure itself to identify the application data set or structure. Furthermore, a list with a value or encoding identifying an application data set or structure can be scanned without reading the structure descriptor itself during the scan, so that once a match is reached, the entry in the list points to the corresponding structure data or the corresponding application dataset.

A default subset or all subsets of all application data sets may be scanned, or alternatively, scanning may continue until an application data set or structure corresponding to a predetermined need is found.

For manufacturers of electronic equipment, the described invention can support standard chargers by employing certain standard string descriptors with structures. A manufacturer can also utilize a vendor-specified string descriptor and thereby only support his or her own brand of chargers. Optionally, the electronic device 1 may even expose several structures, so that the device supports a variety of different chargers, standard and specified by the vendor.

Another advantage of the system according to the invention is that various functions of the electronic device 1 can be triggered when the device is connected to external electronic units such as OBEX (Object Exchange), modems and mass storage used on mobile terminals, while When the electronic device 1 is connected to the charging device, these functions will not be triggered because they will not appear in the charger structure 101 .

The system according to the invention is very small compared to existing systems, and the cost of design changes is small. The minimum significance on the electronic device 1 for supporting the solution according to the present invention is only to add an application data set 10 or a structure 101 in the memory 8 of the electronic device 1, for example, comprising a structure descriptor 10a and a string descriptor 10c . If the structure descriptor is within the standard USB protocol, the electronic device will be able to handle other descriptors, and there is no need to add specific encoding support for the charger protocol, and optional commands can be ignored in some functional descriptors support. If selected parts of the charger protocol are required, of course some coding must be written to support those parts. An optional charger command can provide functionality such as reading charge status from the device and can provide more than 500mA of power consumption for faster charging.

If USB is used to specify the communication protocol, the charging device can be implemented using a microcontroller with an embedded USB host. This enables easy realization of various functions of the charging device according to the present invention.

In the case of a USB interface, the present invention allows the electronic device to use a standard USB Type B, Mini-B or Mini-AB connector and allows the user to use a standard cable. This is advantageous over using a dedicated connector for the USB charging cable, which has the disadvantages of increased tooling costs, possibly increased space requirements, and inconvenience to the user.

The invention allows the use of standard electronics in the device and requires only a small amount of electronics added to the charging device compared to chargers according to the prior art. Additionally, chargers can be standardized and used across multiple devices, allowing economies of scale to reduce costs.

In addition to the advantages mentioned above, using the system according to the invention avoids certain specific problems that arise when connecting a charger to an electronic device, given that the communication protocol is specified by the USB standard. To illustrate this point the following example is given. Referring to the case of connecting the electronic device 1 to an external electronic unit, the following provides a case where USB is used as a communication protocol standard:

Compliant devices need to follow the power requirements given in the USB specification. These regulations can be summarized as follows: Although the host (external electronic unit 4a) provides a certain amount of power on Vbus pin 5 (Figure 1#5), the specification allows the host to follow certain principles to change the amount of power provided . If the equipment does not follow these principles, it may cause the system to malfunction. For example, an overcurrent protection in the host section may be triggered, rendering the host section inoperative. As another example, a system's power design constraints may be violated, preventing the system from waking up from a suspend state.

The specification defines the following device states when the device is physically connected to the host:

· Attached: The device is physically attached to the host, but the Vbus is not powered. With 4 USB cables, the device does not need to distinguish between this state and the physically disconnected state; but the device may have some non-prescriptive way of detecting this connected state.

· Power supply: The device is attached, Vbus is valid, but has not been reset.

Default: The device is attached, Vbus is valid, and the device has been reset at least once; but since the last time the device was reset, it has not been assigned a non-zero address.

· Addressing: The device is attached, Vbus is valid, and the device has been reset at least once; the device has been assigned a non-zero address, but the device has not been assigned a non-zero structure value.

Configuration: The device is attached, Vbus is valid, and the device has been reset at least once; the device has been assigned a non-zero address, and the device has been assigned a non-zero structure value.

Suspended: The device was most recently in one of the states (powered, default, addressed, or configured), but had no bus activity for at least 3 milliseconds. The device remains in this suspended state as long as there is no traffic. When business resumes, the device returns to its previous state.

Electrically, the device detects that it is powered by detecting the presence of Vbus relative to ground. The host detects the presence of the device by first supplying Vbus and then checking for specific voltages at points that will go to D+ and D-. Full-speed and high-speed devices signal the accessory by pulling D+ to Vbus with a 1500 ohm resistor. The low speed device signals the accessory by pulling D- to Vbus with a 1500 ohm resistor.

The specification also states that when switching between attached and powered states, Vbus may be provided to the device, but the device does not signal to the host that the device is attached, (i.e., the D+ or D- pull-up resistors are electrically disconnected or ground). The conformance test process requires that the device must connect D+/D- to Vbus within 100 milliseconds of detecting Vbus.

The USB conformance test process requires the device to follow the following principles:

1. Initially, when the device is connected to the host, the device enters the powered state. The device can draw 100mA from Vbus for up to 100ms; the device must then enter the "Powered" state.

2. In the "power supply", "default" and "addressing" states, the device can draw 100mA current, but must recognize the existence of bus traffic and the switch to the "pause" state.

3. In the "configured" state, the device can draw as much power as specified by the power delivery scheme 9d, 1Od in the fabric descriptor 9a, 10a corresponding to the fabric selected by the host.

4. In the "Suspend" state, the device can draw a maximum current of 500μA.

Now, consider a situation where an electronic device is attached to a charger according to the prior art using Vbus (Figure 2 #5), whereby the charger is connected to a standard USB socket on the device. This charger does not generate any traffic on the USB bus. The USB part of the device cannot distinguish between a charger and a normal USB host. Therefore, it is necessary to:

1. Signal the attach within 100 milliseconds of the cable being attached

2. Limit the drawn current to 100mA

3. Properly detects a suspend condition and reduces power consumption to 500 microamps within 3 milliseconds after transitioning to the "Powered" state. Of course, once the device draws less than 500 microamps, charging becomes ineffective.

Since the present invention provides a solution for connecting a device to a charger through the enumeration process described above, this problem is avoided and the battery pack of the device can be charged efficiently. In case the USB interface is used with the system according to the invention, a current of up to 500 mA can be supplied to charge the accumulator means in the electronic device.

It should be noted that the electronic device 1 could also just be an electric accumulator to be connected to a charging device which supplies power to the accumulator. Therefore, the connector 3 will actually only be used to attach the charging device 4b to the electronic device 1 . Thus, only one application data set according to the communication protocol can be stored in the electronic memory 8 provided in the electronic device 1 , so that the application data set includes the data requested according to the communication protocol for charging the accumulator device with the charging device. Alternatively, two or more application data sets according to the communication protocol may be stored in the electronic memory 8, so that at least two of the application data sets include data requested according to the communication protocol for charging the battery with the charging device The device is charging. Therefore, each application data set can include various functions for connecting to a charger with specific specifications. In this way, using the same connector in all cases, certain chargers with specific specifications, e.g. considering charging current, in one case can be connected to the device, while other chargers with different specifications in other cases It is also possible to connect to this device.

In the above, USB was taken as an example of the communication protocol constituting the connection between the electronic device and the charging device. However, other communication protocols of the so-called master-slave type can also be used.
