Description

Power supply

The present invention relates to a power supply device.

In recent years, with the spread of PLC (Power Line Communication), the demand for communication with external devices outside the home (for example, electric vehicles) has increased, but at the same time, the intrusion from the external power line network into the home power line network There is also an increased risk.

In recent years, there has been a great expectation for the spread of electric vehicles as a countermeasure against global warming. Here, the electric vehicle needs to be connected to a power line via a charging cable, for example, when charging at home or away from home. When connecting to this power line, there is a possibility that information may be transmitted through power line communication through this power line. Therefore, it is essential to separate and integrate the network with the home and the charging terminal.

Therefore, the following technologies have been reported to suppress the signal passage of power line communication.

For example, in the power line communication system described in (Patent Document 1), the power line communication system that constitutes a plurality of groups of local area networks does not hinder the transmission of commercial alternating current to the indoor distribution lines between the groups. A blocking filter that suppresses communication signals is provided. This blocking filter has a core formed of a magnetic material, and passes or passes through the electric lines of the indoor distribution line so that magnetic fluxes in the same direction in the core are generated by currents flowing simultaneously using these electric lines as the forward path and the return path. The signal of power line communication is suppressed by winding.

A capacitor (corresponding to C101) may be inserted.

Thus, the filter unit 11 includes at least one of an LPF (low-pass filter), an inductor (coil), or a capacitor.

(Embodiment 13)
Next, Embodiment 13 will be described below with reference to FIG. FIG. 17 is a diagram illustrating a specific example of the hardware configuration of the power supply device 1 according to the thirteenth embodiment. The same reference numerals are given to the same components as those of the embodiments described so far.

The external device 60 is an electrical device connected to the in-house power line network 31 and has a power line communication function. As an example of the external device 60, a home appliance or a personal computer (PC) having a power line communication function is conceivable.

The power receiving unit 1 is connected to the home power line network 31 and receives supply of commercial power (frequency power, AC power of 60 Hz). The electric vehicle 40 is connected to the outside connection unit 14 of the power supply device 1 via a power supply cable, and receives commercial power supplied from the in-home power line network 31. The electric vehicle 40 includes a power line communication unit 43, a charging circuit 44, and a battery 45. The charging circuit 44 performs AC / DC conversion on the commercial power received by the electric vehicle 40, and supplies power to the battery 45 using the DC power.

The filter unit 11 has a high impedance with respect to the power line communication signal (frequency: 2 to 30 MHz), and blocks the power line communication signal traveling between the home power line network 31 and the electric vehicle 40. The bypass unit 12 is installed in order to bypass the filter unit 11 with a power line communication signal traveling between the home power line network 31 and the electric vehicle 40. Since the specific circuit configuration of the bypass unit 12 is the same as that of the above-described embodiment, the description thereof is omitted.

The power line communication unit 22 is provided in the power supply device 1 and performs power line communication with the power line communication unit 43 of the electric vehicle 40. The control unit 13 performs control of whether or not the bypass unit 12 described above functions and authentication processing of the electric vehicle 40. The power line communication unit 43 of the electric vehicle 40 transmits a power line communication signal storing unique information of the electric vehicle to the power line communication unit 22 of the power supply device 1. The power line communication unit 22 reads the unique information from the power line communication signal and transmits the unique information to the control unit 13. The control unit performs authentication processing of the electric vehicle 40 using the specific information. When the authentication is successful, the control unit 13 transmits a signal to the bypass unit 12 and enables the function of the bypass unit 12. As a specific method for causing the bypass unit 12 to function, for example, it is conceivable to provide switches (relay switches or the like) in the bypass path of the power line communication signal.

The switch 80 is provided in a route between the filter unit 11 and the outside connection unit, and connects / disconnects the route. In the stage of starting up the power supply device 1, the switch 80 is maintained in a state of connecting paths.

The control unit 13 has a timer unit 70. The timer unit has a function of measuring a predetermined time (for example, several tens of seconds to several minutes). It is desirable that the predetermined period measured by the timer unit 70 is set to be longer than the time necessary for the authentication process of the power supply device 1 and the electric vehicle 40. If the authentication process is not completed even after the timer unit 70 finishes measuring the predetermined period, the control unit 13 regards that the authentication process has failed and transmits a signal to the switch 80. Control to disconnect.

By linking the switch 80 and the timer unit 70 as described above, it is possible to supply commercial power to the electric vehicle 40 during the period when the electric vehicle 40 and the power supply device 1 are performing the authentication process. Therefore, even when it is difficult to secure a power source for operating the power line communication unit 43 (for example, when the remaining amount of the battery 45 is low), the power line communication unit 43 can be stably operated, and the authentication is performed. It becomes possible to execute the processing reliably.

In addition, when the authentication fails, it is possible to reliably prevent power supply of an electric vehicle without a proper authority by turning off the switch 80.

Note that the place where the switch 80 is installed may be between the power receiving unit 10 and the filter unit 11.
