`Description |.
`
`~
`
`[0001] Thepresent invention relates to a chargingcir-
`cuit for charging a mobile terminal of a wireless telacom-
`munication system through a USB Interface of a com-
`. puter and to a mobile terminal for a wireless telecom-
`“munication system adapted to be connected to and
`charged by such a charging circult.
`[0002] Charging circuits for charging batteries of ac-
`cumulators of mobile terminals are knownin the art, For
`_' example, US 6,870,615 discloses a specially designed
`~ PCMCIA card comprising a charging cireuit for charging
`. the battery of a cellular phone and an adapter cable hav-
`Ing a battery characteristic encoder integrated at one
`“end. However, a POMCIA card can only be used with
`. portable computers, such as laptops, notebooks or the
`like so that the proposed way of charging a mobile ter-
`minal is limited to these applications.
`.
`[0003] . The object of the present invention Is therefore
`to propose a charging circuit for charging a mobile ter-
`_.
`. minal of a wireless telecommunication system and a
`' mobile terminal adopted to ba connected to and charged
`by such a charging circuit, which can be used with dif-
`. ferent kinds of computersina simple and effective way.
`[0004] The above objectis achieved by a charging elr-
`. suit for charging a mabile terminal of a wireless telecom- °
`' munication system through a USB interface of a com-
`' puter, with tirst connection means for a connection with
`“the USB Interface of a computer, second connection
`. Means for a connection with a mobile terminal to be
`’ charged, and adaptation means for adapting power re-
`_ ceived from said USB interface to the power require-
`_Ments of a mobile terminal to be charged.
`-, [0005] Most ofthe available computers, such as PCs,
`_ laptops, notebooks and the like, are equipped with a
`._ USB interface (universal serial bus interface} far con-
`'. nection with other devices. The USB interface is realised
`_ with a standardised USB port inthe computers, to which
`"a corresponding USB plug from a USB datacable is con-
`nected. The USB interfaca comprises fourlines, namely
`two data lines, one power line and one ground line, The
`charging clreult according to the present Invention there-
`fore presents a very flexible and universally usable way
`of charging a mobile terminal of a wireless telecommu-
`nication system, Particularly, the charging circuit ac-
`cording to the present invention has the advantage that
`a mobile terminal for a wireless telecommunication sys-
`tem can be charged at any place of the world with only
`a single charging cireult. Normal charging cables for mo-
`bile terminals are only adapted to the specific power
`supply system used in the respective country. A USB
`interface, however, is an internationally used and stand-
`ardised way of connecting devices to computers.
`[000s] Advantageously, the adaptation means of the
`charging circult according to the present invention com:
`prises a current limiter to limit the current received from
`the USB interface to a maximurn charging current of the
`mabile terminal, The current timiter Is advantageous |n

`
`respect of protection against TDMA bursts and other
`kinds of bursts used in the mobile terminal for the wire-
`less transmission of data. Further advantageously, the
`adaptation means camprises a short circuit protection
`means for protecting the mobile terminal and/or the
`computer against short circuits. Further advantageous-
`ly, the adaptation means comprises @ voltage regulator
`for regulating the voltage received from the USB inter-
`face to the charging requirements ofthe mobile terminal.
`The voltage regulator is particularly advantageous for
`stabilising the voltage supplied to the mobile terminal,
`[0007]
`(/thas to be understood, that in the present ap-
`plication,
`the expression charging a mobile terminal
`means charging of the battery cr the accumulator of a
`mobile terminal,
`(0008]
`Further advantageously, the first connection
`means is a USB cable for connection with a USB port
`of the computer and the second connection means Is a
`mobile terminal cable for connection with a correspond-
`ing data input/output and charge part of the mobile ter-
`minal. Here,
`the charging circuit according to the
`presentinvention Is an independent device with respec-
`tive cables for the connection with tha computer and the
`mobile terminal. Alternatively, the charging circult ac-
`cording to the present invention can be bullt in tha mo-
`bile terminal or the computerto that an integrated solu-
`tion is realised.
`In further alternative solutions,
`the
`charging circult according to the present invention could
`have a USB port as the first connection means and/or
`a respective mobile terminal cable port as the second
`connection means. Here. standardised cables and
`plugs could be used as the cable connections between
`the computer as a charging clroult and the charging cir-
`cult and the mobile terminal. A further advantage of this
`solution is that the charging circuit according to the
`present invention could be used with different kinds of
`mobile terminals having different kinds of data input/out-
`put and charge ports for the connection with the charg-
`ing clreuit.
`(0008]
`Further, the charging circuit according to the
`present invention advantageously comprises adataline
`for transmitting power supply status Information from the
`computer to the mobile terminal. The charging circuit ac-
`cording to the present invention as described above
`does not necessarily need to enable a data transfer be-
`tween the computer and the mobile terminal and the
`conversion and adaptation of power received from the
`computer to the power requirements for charging the
`mobile terminal is generally sufficient for the purpose of
`the present invention. However, the communication of
`data between the computer and the mobile terminalis
`necessary for embodiments in whichthe charging of the
`mabile terminal is controlled in dependence of the status
`of the power supply of the computer,
`[0010] The above objectis further achieved by a mo-
`bile terminal for a wireless telacommunication aystem
`according to claim 8, which comprises a battery provid-
`ing power supply, connection means adapted to be con-

`
`nected to a charging circuit of the above described kind,
`and control means for controlling the charging of the bal-
`tery from a USB interface of a computer.
`[o011] Thebattery of the mabile terminal according to
`the present invention which is to be charged by the
`charging circult as above described, is for example part
`" of a removable battery pack of accurnulater of the mo-
`. bile terminal. The connection means of the mobile ter-
`_ mina! adapted to be connected to the inventive charging
`_. Circuit is for example a data input/output and charge port
`of the mobile terminal, which serves also for other pur-
`poses, such as connecting a hands free kit or thelike.
`© The control meansfor controling the charging ofthe bat-
`- tery is for example the central control microchip or mi-
`_croprocessor af the mobile terminal responsible for can-
`- trolling the common functionalities. The wireless tele-
`" communication system, In which the mobile terminal ac-
`_ cording te the present invention operates, can for exam-
`‘ple be the GSMand/or the UMTS and/or anyother wire-
`_
`lees telecommunication systsem. .
`_ [0012] Advantageously, the contra! means of the mo-
`.. bile terminal detects the charge level of the battery and
`controls the charging of the battery froma USB interface
`through a connected charging circuit an the basis of the
`» detected charge level. Hereby, the control maans ad- —
`vantageously charges the battery if the detected charge
`level is below a pre-set value. This value can for exam-
`. ple be about 5% of the entire battery capacity.
`|n this
`', exampleof the mobile terminal according to the present
`"s, invention, charging of the battery is performed only on
`' the basis of the charge level of the battery and neo further
`other Information is used. Thus, the charging clreult can
`. be reduced to the pure power conversion and adapta-
`tlon function In order to deliver the specific voltage and
`_ current to the mobile terminal. The charging processis
`only controlled by the mobile terminal itself and not by
`the computer or the user. Alternatively, the charging elr-
`~ cuit can, additionally to the power lines, comprise data
`lines for communicating data between the computer and
`the mobile terminal. In this way, the mobile terminal can
`be charged via the USB interface, while atthesame time
`the data communication, for example for downloading
`oF uploading data from and to the computer, can be per-
`formed.
`In a further alternative example of the mobile
`(0013)
`terminal according to the present invention, the control
`means is adapted to receive a power supply status In-
`formation of a computer through a connected charging
`clroult and controls the charging of the battery from a
`USB Interface of the computer through the connected
`charging circuit on the basis of the received power sup-
`ply status information, Here, charging of the battery of
`the mobile terrninal
`is performed only if the received
`power supply status information indicates that the power
`supply status of the computer allows charging of the bat-
`tery of the mobile terminal. Advantageously, the control
`means charges the battery If the received power supply
`status information indicates that the computer is con-
`
`fed
`
`20
`
`a0
`
`40
`
`nected to and powered by an exterhal power supply, Ih
`this case,
`the battery of the mobile terminal js thus
`charged through the external power supply of the com-
`puter in any case in which the battery of the mobile ter-
`minal is not fully charged. Further advantageously, the
`control means is adapted to detect the charga level of
`the battery and charges the batteryif the received power
`supply status Information indicates that the computer is
`powered by an internal power supply and that the de-
`tected charge level is below a pre-set value, The pre-
`set value is acivantageously about 5% of the entire bat-
`tery capacity. Here, in order to save powerfor the com-
`puter, the battery is only charged If its charge level is so
`fow that there is a risk that the mobile terminal cannot
`be further operated dueto a lack of power. Thelast case
`is particularly appticable to mobile computers, such as
`laptops, notebooks and the like, which have an internal
`pewer supply In form of a detachable battery pack, an
`accumulator or the like. Here itis very important that the
`power resources of the computer as well as the mobile
`terminal are carefully controlled to ensure proper oper-
`ation.
`It is to be noted that in the example of the mo-
`[0014]
`bile terminal contralling the chargingofits battery on the
`bagls of a power supply status Information received from
`the computer, the computer needs an appropriate driver
`software which detacts the power status of the computer
`and transmits a corresponding Information via the USS
`interface to the mobile terminal. Hereby, the data line of
`the charging circuit according to the present invention
`usec for the transmission of the power supply status in-
`formation between the computer and the mobile terml-
`nal can also be used for the communication of down-
`load/upload data and the like.
