Abstract: In a vehicle (100), a power storage device (110) mounted thereon can be charged with electric power transmitted from an external power supply device (500, 500A) via a power cable (400, 400A). The vehicle (100) includes a PLC communication unit (230) for establishing PLC communication with the external power supply device (500, 500A) via the power cable (400).

Abstract: An electric powered vehicle is equipped with a main battery for storing electric power input to and output from a motor, and an auxiliary battery as a power source for an auxiliary system including a control system. A DC/DC converter converts an output voltage of the main battery to a level of an output voltage of the auxiliary battery. During operation, a BAT-ECU monitors states of charge of the main battery and the auxiliary battery and controls operation/stop of the DC/DC converter. When the electric powered vehicle is in a key-off state (running stop state), the BAT-ECU is intermittently operated, while an external charging system and a vehicle running system are stopped.

Abstract: A switch sets the voltage level of a control line to a first level corresponding to a first voltage by electrically coupling the control line with a first node when manual operation is not executed. The switch sets the voltage level of the control line at a second level corresponding to a second voltage by electrically coupling the control line with a second node during a period of time over which manual operation is executed. An ECU switches the operation mode of a hybrid vehicle having first and second power sources between a first mode in which the first power source is used having higher priority for the running of the hybrid vehicle, and a second mode in which said second power source is used having higher priority for the running of the hybrid vehicle, based on a change of the voltage level of the control line.

Abstract: A switch of a connecting circuit is connected between a signal line branched from an input terminal for a pilot signal in a charging inlet and a ground line connected to a vehicle earth, and is turned on/off in response to a control signal from a CPU. The CPU causes the switch to be turned on when a connector is not connected to the charging inlet, and detects a break in a control pilot line based on whether or not a change in the potential of the pilot signal occurs at that time.

Abstract: A device controls charging a battery with power supplied from a power supply located outside of a vehicle through a charge cable. The device includes a first microcomputer and a second microcomputer. The first microcomputer is configured to turn on a charge mode signal upon detecting a change in a pilot signal output through the charge cable, and to turn off the charge mode signal when a charge completion signal output from the second microcomputer is turned off. The second microcomputer is configured to charge the battery through the charge cable when the charge mode signal is turned on, and to turn off the charge completion signal when the charging is complete. When the charge completion signal is turned on at the time of the first microcomputer turning off the charge mode signal due to sudden fluctuations, the charge mode signal is turned on again.
