Patent number: 11916409Abstract: A power transmitting device includes a power transmission unit using contactless power supply, processing circuitry configured to switch a power transmission mode of the power transmission unit between a normal output mode and a limit mode, and a transmission-side communication unit configured to execute communication with a power receiving device. The processing circuitry is configured to determine whether the power receiving device is a registered power receiving device based on information related to the power receiving device obtained from the transmission-side communication unit, determine whether the registered power receiving device is located inside a power transmission range of the power transmission unit, set the power transmission mode to the normal output mode when determining that the registered power receiving device is located inside the range, and set the power transmission mode to the limit mode when determining that the registered power receiving device is not located inside the range.Type: GrantFiled: January 6, 2023Date of Patent: February 27, 2024Assignee: TOYODA GOSEI CO., LTD.Inventors: Atsushi Sugihara, Shinichiro Fuki, Kazuhito Kawamura, Yuki Tokuyama

Publication number: 20230246487Abstract: A power transmitting device performs power transmission to a power receiving device. The power receiving device is provided in a space that a person can enter or exit. The power transmitting device includes a power transmitting unit, a processing circuitry, and a reception unit. The power transmitting unit is configured to perform power transmission to the power receiving device through contactless power supply. The processing circuitry is configured to switch a power transmission mode of the power transmitting unit between a normal-output mode and a limit mode in which a transmitted power is more limited than in the normal-output mode. The reception unit is configured to receive a limit instruction for the power transmission given by the person. The processing circuitry is configured to set the power transmission mode to the limit mode when the reception unit receives the limit instruction.Type: ApplicationFiled: January 13, 2023Publication date: August 3, 2023Inventors: Yuki TOKUYAMA, Shinichiro FUKI, Tomokazu SAKAI, Atsushi SUGIHARA, Kazuhito KAWAMURA
