    • A power supply device includes battery equipment and voltage detecting circuitry. The battery equipment includes positive-side and negative-side battery blocks that are connected to each other at a reference midpoint. The voltage detecting circuitry detects the respective voltage values of serially-connected battery modules of the battery equipment. The voltage detecting circuitry includes positive-side and negative side voltage management ICs with respect to the reference midpoint. The positive-side and negative side voltage management ICs manage the voltage conditions of the battery modules in the positive-side and negative-side battery blocks, respectively. Positive-side and negative-side voltage power lines of each of the positive-side and negative side voltage management ICs are connected to positive-side and negative-side output terminals of the battery equipment so that all the battery modules supply electric power to each of the voltage management ICs. The voltage management ICs have a common ground line.

    • A battery pack having a contactless charging circuit (95) that rectifies power received by a receiving coil (1), and a battery pack control section (91) with a connection decision section. The battery pack control section (91) is configured to judge whether or not the battery pack is connected to the body of a battery powered device (101) based on the rectified voltage of the contactless charging circuit (95). This decision utilizes the fact that the charging circuit is in a no-load condition and the rectified voltage is high when the battery pack is not connected to the battery powered device, and allows reliable judgment of whether or not the battery pack (90) is attached to the battery powered device.
    • 一种电池组,具有对由接收线圈(1)接收的功率进行整流的非接触充电电路(95)和具有连接判定部分的电池组控制部(91)。 电池组控制部(91)被配置为基于非接触充电电路(95)的整流电压来判断电池组是否连接到电池供电装置(101)的主体。 该决定利用充电电路处于空载状态并且当电池组未连接到电池供电装置时整流电压高的事实,并且允许可靠地判断电池组(90)是否为 连接到电池供电设备。
