    • The present invention refers to a power transfer system which comprises a power transfer device (10) as well as at least one portable device (20). The power transfer device (10) includes at least one coil arrangement (CA) for generating or receiving a magnetic field, and a first controller (15) coupled to the coil arrangement (CA) for driving the coil arrangement (CA) to supply power to the portable device (20) placed upon the power transfer device (10), via the generated magnetic field. The portable device (20) includes a further coil (23) for generating and receiving a magnetic field, a battery power source (21), and a second controller (22) coupled to the further coil (23) for supplying power received via the magnetic field generated by the power transfer device (10), to charge the battery power source (21). Specifically, the first controller (15) and the second controller (22) are adapted to respectively drive the coil arrangement (CA) of the power transfer device (10) and the further coil (23) of the portable device (20) to establish between the power transfer device (10) and the portable device (20) a near field communication link (NFC link) (32) for transferring data, and a power transfer link (31) for supplying power for charging the battery power source (21) of the portable device (20).

    • The present invention relates to a power transfer system which comprises a power transfer device (10) as well as at least one portable device (20), and to a method of controlling the power transfer system specifically in case of a dead battery condition of a battery (21) of the portable device (20). The power transfer device (10) for wireless charging of the battery (21) arranged in the portable device (20) and the power transfer device (10) each comprise a near field communication functionality for data communication by a data communication link (32) between the devices. The method includes a step of starting to establish the data communication link (32) between the power transfer device (10) and the portable device (20). When the establishment of the data communication link (32) is started, the power transfer device (10) requests the portable device (20) to transmit an identification information via the data communication link (32) to the power transfer device (10). It is then detected whether the identification information of the portable device (20) is received by the power transfer device (10). Depending upon whether the identification information is received a setting is performed for setting a charging power to be transferred from the power transfer device (10) to the portable device (20). The setting provides a reduced charging power not exceeding a first predetermined value when the identification information is not received. Depending upon this setting a power transfer link (31) is established by the power transfer device (10), and the charging power not exceeding the first predetermined value is transferred to the portable device (20) so that the portable device (20) can be powered by this transferred power to enable data communication and to charge the battery (21).
    • 本发明涉及一种包括功率传输设备(10)以及至少一个便携式设备(20)的功率传输系统,并且涉及特别是在电池电量不足的情况下控制功率传输系统的方法 便携式设备(20)的电池(21)。 用于对设置在便携式设备(20)和功率传输设备(10)中的电池(21)进行无线充电的功率传输设备(10)各自包括用于通过数据通信链路(32)进行数据通信的近场通信功能, 设备之间。 该方法包括开始建立功率传输设备(10)和便携式设备(20)之间的数据通信链路(32)的步骤。 当数据通信链路(32)的建立开始时,电力传输设备(10)请求便携式设备(20)经由数据通信链路(32)向电力传输设备(10)传输标识信息。 然后检测便携式设备(20)的识别信息是否被电力传输设备(10)接收到。 根据是否接收到识别信息,执行设置以设置要从电力传送装置(10)传送到便携式装置(20)的充电电力。 当未接收到识别信息时,该设置提供不超过第一预定值的降低的充电功率。 根据该设置,电力传输链路(31)由电力传输设备(10)建立,并且不超过第一预定值的充电电力被传输到便携式设备(20),使得便携式设备(20)能够 由该传输的电力供电以启动数据通信并为电池(21)充电。
