[0080] (First embodiment)
[0081] figure 1 (A)~figure 1 (C) shows an outline of a configuration example of a non-contact power transmission system that can switch between the switch mode and the automatic mode. figure 1 The non-contact power transmission system of (A) includes: a power transmission side device (for example, a charger (pallet)) 500; a power receiving side device (for example, a mobile phone terminal) 510, which is mounted on the power transmission side device 500 and passes through Contact power transmission charges the secondary battery (battery). The power transmission device 10 is built in the power transmission side equipment 500. In addition, the power receiving device 40 is built in the power receiving device 510. The power receiving device 40 can be mounted on the power receiving device 510 from the outside using an adapter or the like.
[0082] figure 1 (A) The non-contact power transmission system can switch between switch mode and automatic mode. A...
Example
[0151] (Second embodiment)
[0152] In this embodiment, the operation of the contactless power transmission system when the automatic mode is selected will be described.
[0153] (Outline of operation of power transmission device in automatic mode)
[0154] Figure 8 It is a schematic flowchart showing an example of the operation of the power transmission device in the automatic mode. As described above, the power transmission side control circuit 22 of the power transmission device 10 of the present invention can automatically detect the settings of the power receiving side equipment 510, and can also perform recharge management after a full charge. Therefore, the operation mode in which the power transmission device 10 automatically performs a series of operations is referred to as an automatic mode.
[0155] in Figure 8 As shown in the part enclosed by the thick dashed line, the operation of the power transmission device 10 in the automatic mode is roughly divided into "setti...
Example
[0297] (Third embodiment)
[0298] In this embodiment, the operation procedure of the non-contact power transmission system in the switching mode will be described.
[0299] (Outline of operation of power transmission device in switch mode)
[0300] Figure 24 It is a schematic flowchart showing an example of the operation of the power transmission device in the switch mode. As shown in the part enclosed by the thick broken line, the operation of the power transmission device 10 is roughly divided into "confirmation of the power transmission object (step SA)" before power transmission and "confirmation of the power transmission environment during power transmission (including before power transmission) (step SB)" .
[0301] As described above, the power transmission device 10 starts temporary power transmission when the switch (SW1) is turned on (steps S1, S2).
[0302] Next, it is confirmed whether the installation position of the power receiving device 510 is appropriate (step ...
