A charging unit for wireless power transfer is described. The charging unit comprises at least one coil for inductive power transmission, an array of sensor coils sensing the presence of at least one foreign matter with a sensing field, and a controller. The controller is configured to move the sensor coil array and/or the sensing field such that the sensing field can scan a sensing area, and is configured to detect the presence of the at least one foreign matter in the sensing area based on a sensing array output. The array of sensor coils and/or the sensing field are movable such that the sensing field may: a) be positioned in the sensing area such that the sensing field does not overlap with the at least one foreign object, and b) be positioned within the sensing area such that the sensing field overlaps with the at least one foreign object.

    本发明描述了一种用于无线电力传输的充电单元。所述充电单元包括:至少一个用于感应电力传输的线圈、一个用感测场感测至少一个异物存在的的‑感测器线圈阵列以及控制器。所述控制器被配置为移动所述感测器线圈阵列和/或感测场,使得所述感测场可以扫描感测区域,且被配置为基于感测阵列输出而检测出所述感测区域中所述至少一个异物的存在。所述感测器线圈阵列和/或感测场是可移动的,使得所述传感场可以:a)定位在所述传感区域中,以使所述传感场不与所述至少一个异物重叠,以及b)定位在所述传感区域内,以使所述传感场与所述至少一个异物重叠。
