20120187905 | COMMUNICATION APPARATUS - A charging system supplies charging power from a charging station to an in-vehicle system through a power line. The charging station and the in-vehicle system further include communication devices, which communicate through the power line. The in-vehicle system includes a detecting circuit for detecting impedance of the power line. The in-vehicle system includes a control circuit, which controls switching-over of the communication device between a waiting state and an operating state based on the impedance detected by the detecting circuit. For example, the control circuit detects connection of the cable based on the impedance change of the power line. | 07-26-2012 |
20130218756 | CHARGING PAYMENT SYSTEM AND TARGET APPARATUS USED IN THE SAME - A charging fee payment system is used for a payment process for a payment of a charging fee to charge a target apparatus with a charging apparatus. The target apparatus includes a memory, a controller, and a communication section. When the charging apparatus does not have a function to communicate with an external server that performs the payment process, the memory stores an unique ID code of the charging apparatus and electricity usage data indicative of the amount of electricity used by the charging apparatus to charge the target apparatus. The controller allows the target apparatus to be charged with the charging apparatus on a condition that the ID code remains stored in the memory. When the communication section becomes able to communicate with the external server, the communication section sends the ID code and the electricity usage data stored in the memory to the external server. | 08-22-2013 |
20130260696 | VEHICULAR COMMUNICATION APPARATUS - A vehicular communication apparatus includes a communication device and an adjuster. The communication device exchanges a signal with an external communication device that is disposed external to the vehicle. The adjuster adjusts a transmission output of the communication device based on at least one of an operation mode of a vehicular device, which influences the communication device by generating a noise, or a classification of a signal exchanged between the communication device and the external communication device. The vehicular communication apparatus either prevents a deteriorated operation quality of the vehicular device or prevents a deteriorated communication quality of the communication device. | 10-03-2013 |
20130268159 | ENERGY GENERATION CONTROLLER - An energy generation controller for a vehicle includes: an internal combustion engine; an energy generating device for converting a driving force of the engine to a predetermined type of energy, an energy generating amount being controlled by a control signal; an energy storage device for storing the predetermined type of energy; an output device for determining and outputting the control signal for generating a target energy amount of the energy generating device when the internal combustion engine is in a predetermined operating state; a detector for detecting an energy accumulation amount stored in the energy storage device; a comparison device for comparing the energy accumulation amount with an assumption accumulation amount estimated by the control signal; and an adjustment device for adjusting the control signal according to a comparison result of the comparison device. | 10-10-2013 |
20140145503 | ELECTRIC POWER CONTROL SYSTEM - An electric power control system includes an electric power supply system, a load, a power source switching unit, a charge-discharge switching unit, a converting unit, an electric power storage device, a discharge detection unit, a power supply detection unit, and a control unit. The control unit controls the discharge detection unit to detect a state of a first AC power converted by the converting unit from a DC power charged in the electric power storage device, and controls the power supply detection unit to detect a state of a second AC power supplied from the electric power supply system. The control unit regulates the first AC power based on a phase difference between the first AC power and the second AC power, and supplies the first AC power to the load. | 05-29-2014 |
20150088354 | ELECTRIC POWER SUPPLY CONTROLLER FOR VEHICLE - A restart section in an electric powered vehicle restarts a controller from a sleep mode, when a voltage higher than a restart voltage is supplied for over a response time. In a charge mode, a stand controller provides a connection check function by using a normal CPLT (Control Pilot signal) method. In a normal CPLT method, an output terminal is supplied with DC voltage that exceeds the restart voltage. In a non-charge mode, the stand controller uses a monitor signal which will not cause a restart of the controller to provide a connection check function. The monitor signal for the non-charge mode has a voltage that is lower than the restart voltage and/or a pulse width that is shorter than the response time. As a result, it is possible to reduce power consumption. | 03-26-2015 |
20150155711 | AC POWER SUPPLY SOURCE SWITCHING APPARATUS - A mechanical switch and a semiconductor switch are connected between a load and a power supply system. A mechanical switch and a semiconductor switch are connected between the load and a secondary battery side. A control part turns on the mechanical switch, turns off the semiconductor switch, turns on the semiconductor switch and turns off the mechanical switch sequentially. In addition or alternatively, the control part turns on the mechanical switch, turns off the semiconductor switch, turns on the semiconductor switch and turns off the mechanical switch. | 06-04-2015 |
20150162783 | AC POWER SUPPLY SOURCE SWITCHING APPARATUS - An AC power supply source switching apparatus includes a switch and a switch connecting a load to an AC power supply system and a DC secondary battery, respectively. When one switch, which is driven to turn off, did not actually turn off, the switch is driven to turn off again after being turned on. When an impedance of the load decreases and a load current flows in a load line, no AC voltage is developed on the load line. As a result, it is determined that the switch has actually turned off. Then the other switch is turned on thereby to switch over connection of the load. | 06-11-2015 |
