  • Patent number: 11233417
    Abstract: A rechargeable charger that includes a rechargeable battery and charging control circuitry for controlling a charging of at least one portable rechargeable device. The charging control circuitry is configured such that charging is automatically and periodically interrupted after reaching a charged state. During a charging phase energy is transferred from the rechargeable battery to the portable rechargeable device via interface circuitry until gauging circuitry indicates that a threshold value has been reached upon which a pause phase is entered where charging of the portable rechargeable device from the rechargeable battery is suspended. In the pause phase a timer is started, and when the timer has elapsed, the charging phase is started again. As a result, phases of charging the portable rechargeable device and phases of switching off the charging alternate.

  • 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.

    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.

  • 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.
