    • 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).
    • 电力传输系统技术领域本发明涉及一种电力传输系统,其包括电力传输装置(10)以及至少一个便携式装置(20),以及一种在电池电量不足的情况下特别地控制电力传输系统的方法 电池(21)。 布置在便携式设备(20)和电力传输设备(10)中的用于无线充电的电力(21)的电力传输设备(10)每个都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, 在设备之间。 该方法包括开始在电力传输装置(10)和便携式装置(20)之间建立数据通信链路(32)的步骤。 当数据通信链路(32)的建立开始时,电力传输装置(10)请求便携式装置(20)经由数据通信链路(32)向电力传送装置(10)发送识别信息。 然后检测便携式设备(20)的识别信息是否被电力传送装置(10)接收。 根据是否接收到识别信息,执行用于设置要从电力传送装置(10)传送到便携式装置(20)的充电电力的设定。 当未接收到识别信息时,该设置提供不超过第一预定值的减小的充电功率。 根据该设定,电力传送装置(10)建立电力传送连接(31),将不超过第一预定值的充电电力传送到便携式装置(20),使便携装置(20)能够 由该传送的电力供电,以实现数据通信并对电池(21)充电。
