  • Patent number: 11112844
    Abstract: A Universal Serial Bus (USB) Type-C and power delivery port with scalable power architecture is disclosed. In one aspect, at least two circuits for a USB port are consolidated into a single integrated circuit (IC). At least one of the at least two circuits is part of a Type-C port controller (TCPC) group of circuits including sensors associated with detecting whether a voltage and current are present at pins of a USB receptacle. At least the other one of the at least two circuits is selected from a battery-related group of circuits including a battery charging circuit, an over-voltage protection circuit, and a conditioning circuit. The more circuitry integrated into the single IC the more readily scalable the end product is for a multi-port device. Additional circuitry such as a light emitting diode (LED) driver may also be included in the single IC.

  • Patent number: 11114872
    Abstract: A charging device includes: a connector that protrudes from a placement surface; a protective plate; a wall surface intersecting with the placement surface; a support member capable of moving to be in a first orientation in which the protective plate is supported and a second orientation in which the protective plate is not supported; and a lock mechanism that locks the support member in the first orientation. The lock mechanism includes a first protruding part that, when the support member is locked, releases the locking of the support member by being pushed. The support member (i) includes a second protruding part, and (ii) moves from the first orientation to the second orientation by the second protruding part being pushed toward the wall surface in a state where the locking is released. When the support member has moved, the protective plate is capable of moving to the placement stand.

  • Patent number: 11107964
    Abstract: A TEG system is attached to a rotating shaft and generates electricity from radiant energy that is substantially radiatively transmitted through the atmosphere from a stationary source to the TEG system that is rotating with the shaft. The rotation of the shaft provides cooling to the TEG system, but not heat energy. The TEG system includes at least one TEG, each TEG equipped with an energy receiving and heat containment window and an energy conversion system in combination with controlled convection cooling enhanced by an airflow moving in response to the rotation of the rotating shaft. Individual TEGs having controlled convection cooling also are described.

  • Patent number: 11095140
    Abstract: A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

  • Patent number: 11088561
    Abstract: The PWM signal corresponding to the at least one switch is output by reducing the output frequency of the PWM signal to be lower than that of the pervious PWM signal output immediately before the output of the PWM signal so as to prevent overheating during the on/off operation of the at least one switch corresponding to the at least one battery cell so that the at least one switch may perform the cell balancing function without being overheated and thus a voltage and current of a noise component during on/off switching of the at least one switch (e.g., an FET) may be reduced to prevent overheating of the at least one switch (e.g., an FET) and other circuit components (e.g., a capacitor, etc.) near the switch due to the voltage and current of the noise component, thereby preventing a malfunction of the battery management system.
