Patent number: 11207999Abstract: A charger includes a first connection port, a second connection port, a DC-DC converter, a first microcontroller, and a second microcontroller. The DC-DC converter is configured to convert a first DC voltage into a second DC current/voltage according to a regulation signal, and output the second DC current/voltage through the second connection port. The second DC voltage is lower than the first DC voltage. The first microcontroller is configured to communicate with a DC charging station by handshake via the first connection port. When the handshake between the first microcontroller and the DC charging station succeeds, the first microcontroller generates a regulation indication according to a result of the handshake between the first microcontroller and a battery, the second microcontroller generates the regulation signal according to the regulation indication, and the first DC voltage is supplied by the DC charging station.Type: GrantFiled: October 8, 2019Date of Patent: December 28, 2021Assignee: DELTA ELECTRONICS, INC.Inventors: Chung-Hwa Wei, Cheng-Hsien Cho, Hui-Hsin Lin

Patent number: 11208000Abstract: There is provided a vehicle comprising a power storage device; a connecting portion configured to be connectable with an external power source; a converter configured to be connected with the connecting portion and with the power storage device; and a control device configured to control the converter. When the external power source is connected with the connecting portion, the control device performs charging control to control the converter, such that electric power from the external power source is subjected to voltage conversion and is then supplied to the power storage device. On completion of charging of the power storage device, the control device starts a system by using electric power from the power storage device after disconnection of the converter from the external power source.Type: GrantFiled: November 25, 2019Date of Patent: December 28, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yuya Ando, Takeaki Suzuki, Shinsuke Iwasaki, Miki Sugita, Yuko Asano

Patent number: 11203267Abstract: A dual-voltage charging station system for an alternating current (“AC”) power supply and a mobile platform having a charging port includes a charge coupler, an AC-to-DC conversion stage, a cable, and a controller. The charge coupler has AC pins and direct current (“DC”) pins configured to engage with respective AC and DC receptacles of the charging port. The conversion stage is connected to the charge coupler and the AC power supply, converts the supply voltage to a DC charging voltage, and relays an appropriate AC or DC accessory voltage. The cable connects to the charge coupler such that the AC pins receive the accessory voltage and the DC pins receive the DC charging voltage. The controller simultaneously delivers the accessory voltage and the DC voltage to the mobile platform via the AC pins and the DC pins, respectively.Type: GrantFiled: September 23, 2019Date of Patent: December 21, 2021Assignee: GM Global Technology Operations LLCInventors: Rashmi Prasad, Chandra S.

Patent number: 11198372Abstract: An ECU of a vehicle performs processing for diagnosing sticking of a charge relay with an SMR being open. The sticking diagnosis processing is performed while electric power is being supplied from a DC power feed facility to the vehicle. The sticking diagnosis processing includes both-element sticking diagnosis processing and one-element sticking diagnosis processing. The ECU performs both-element sticking diagnosis processing by outputting an output command to the DC power feed facility. When it is determined that both of the charge relays have not stuck in the both-element sticking diagnosis processing, the ECU performs one-element sticking diagnosis processing and diagnoses whether or not sticking has occurred in each of the charge relays.Type: GrantFiled: February 4, 2020Date of Patent: December 14, 2021Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yamato Niwa
