Estimating the term…
A communication system, a communication device, a power supply device, and a vehicle are provided, which can suppress occurrence of communication abnormality while suppressing noise applied to a power supply line to be lower than a predetermined upper limit value of a standard, in communication such as inband communication in which a vehicle and a power supply device are connected to each other via a charging cable containing the power supply line and a control line, and a communication signal is transmitted and received using the control line as a medium. A power supply device 2 reads setting relating to an output for each frequency which is previously stored in a memory 221b, and performs a mapping process of adjusting, based on the read setting, an output waveform relating to transmission of the communication signal to an amplitude previously set for each frequency. Then, the power supply device 2 executes inverse fast Fourier transform on the mapped communication signal to convert the communication signal represented as digital data on a frequency domain into digital data on a time domain, and converts the digital signal into analog signal to be transmitted.
A communication system in which a vehicle including a power storage device and a power supply device that supplies power to the power storage device are connected to each other via a power supply line used for power supply and a control line for transmitting a control signal required for control of the power supply using the power supply line, and a communication signal different from the control signal is transmitted and received using the control line as a medium, wherein
A communication device which is connectable to a control line for transmitting a control signal required for control of power supply using a power supply line, and transmits a communication signal different from the control signal by using the control line as a medium, and
A power supply device which is connectable to an external object to be supplied with power, via a power supply line used for power supply and a control line for transmitting a control signal required for control of the power supply using the power supply line, and transmits a communication signal different from the control signal by using the control line as a medium, and
A vehicle which includes a power storage device, is connectable to an external power supply device that supplies power to the power storage device, via a power supply line used for power supply and a control line for transmitting a control signal required for control of the power supply using the power supply line, and further includes a communication device that transmits a communication signal different from the control signal by using the control line as a medium, wherein
