Embodiment Construction

[0046] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing embodiments of the invention. figure 1 is a schematic diagram showing an exemplary configuration of a communication system according to the present invention. figure 1 An example of applying the communication system of the present invention to a case where from a power supply device 2 such as a charging base or the like to a battery (power storage device) included in a vehicle 1 such as an electric car, a plug-in hybrid car, etc. 10 power supply.

[0047] Vehicle 1 and power supply device 2 can be connected to each other via charging cable 3 . The charging cable 3 includes a pair of power supply wires 31 and 32 for power supply, a ground wire 33 as a conductive wire for grounding, and a control signal for transmitting a control signal such as a control pilot signal (CPLT) for charging control. Line 34. One end of the charging cable 3 is connected to th...

Abstract

The present invention provides a communication system, a communication device, a power supply device, and a vehicle, wherein the communication system is used to connect the vehicle and the power supply device through a charging cable that accommodates a power supply line and a control line, and is used in such as using the control line as a medium In communication such as in-band communication in which communication signals are transmitted and received, it is possible to suppress the occurrence of communication abnormalities while keeping the noise applied to the power supply line at or below a prescribed upper limit. The power supply device (2) reads the settings related to the output of each frequency stored in the memory unit (221b) in advance, and based on the read settings, performs a function for adjusting the output waveform related to the communication signal transmission to the preset Mapping processing of amplitudes set for each frequency. Furthermore, by subjecting the mapped communication signal to inverse Fourier transform, the power supply device (2) converts the communication signal expressed as digital data in the frequency domain into digital data in the time domain, and D / A converts the digital data into an analog data.

Description

technical field [0001] The present invention relates to a communication system, a communication device, a power supply device, and a vehicle by means of a control for transmitting a control signal when a power supply line is used for power supply Wires are used as a medium to send and receive communication signals different from the control signals required to control power supply. Background technique [0002] In recent years, electric vehicles and hybrid vehicles have become popular, which include devices such as a motor and a battery, and travel by driving the motor using electric power stored in the battery. An electric vehicle charges its battery with electric power supplied from an external power supply device. As for hybrid vehicles, plug-in hybrid vehicles have actually been used, which allow their batteries to be charged by an external power supply. The external power supply device is a power supply device installed in ordinary houses or facilities such as commerc...
