Patent number: 10320445Abstract: A communication system comprising: a control line transmitting a control signal for controlling charging of a battery mounted on a vehicle; a reference potential line connected to a reference potential of the vehicle serving as a reference for the control signal; a first PLC communication device connected to the control line and the reference potential line and superposing onto the control signal a differential signal having a higher frequency than the control signal so as to perform communication with an external power supply apparatus; and an inductive element which is provided at a point of connection between the reference potential line 1c and the reference potential or provided in the reference potential line and the inductive element having impedance for a noise having a higher frequency than the control signal is higher than the impedance for the control signal.Type: GrantFiled: November 6, 2015Date of Patent: June 11, 2019Assignees: AutoNetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd., Toyota Jidosha Kabushiki KaishaInventors: Ryo Okada, Takeshi Hagihara, Ryo Tanaka, Nobuyuki Nakagawa, Kengo Hayashizaki

Patent number: 10259328Abstract: When connection of a charging gun is detected, a charging-control ECU wakes up, and turns on a power supply relay to activate a charging-communication ECU. The charging-control ECU subsequently actives a power-control computer by communicating therewith. The power-control computer closes an SMR, and closes a power supply switch to activate a monitoring unit. If an abnormality occurs in inband communication, the charging-control ECU opens the power supply relay, instructs the power-control computer to shift into sleep mode, and subsequently shifts itself into sleep mode. The power-control computer opens the SMR and the power supply switch, and subsequently shifts into sleep mode.Type: GrantFiled: January 7, 2015Date of Patent: April 16, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kengo Hayashizaki, Nobuyuki Nakagawa, Ryo Tanaka

Publication number: 20160221455Abstract: A charging system of an in-vehicle battery (11) is configured to charge the in-vehicle battery with an external charging device (30) capable of performing quick charging. The charging system includes a rainfall information acquiring unit and a controller (15). The rainfall information acquiring unit is configured to acquire rainfall information that is information indicating whether it is raining. The controller is configured to control a charging mode of the in-vehicle battery with the external charging device. Furthermore, the controller is configured to inhibit performing of the quick charging or to reduce an amount of charging current in the quick charging based on the rainfall information, which indicates that it is raining, acquired by the rainfall information acquiring unit.Type: ApplicationFiled: September 8, 2014Publication date: August 4, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroya ANDO, Kengo HAYASHIZAKI, Yukihiro MIYASHITA, Yoshifumi OHMORI
