  • Patent number: 11411407
    Abstract: A battery system with a large-format Li-ion battery pack powers attached equipment by discharging battery cells distributed among a plurality of battery packs. A limp home notification is generated from a smart lithium-ion battery pack to one or more application devices using an analog signal. The battery pack may provide broadcast messages over electronic communication lines, that includes state of charge (SoC), fault status, etc. which can be read by one or more application devices to enter limp home mode. In another example, a “fully charged” notification is generated from the smart lithium-ion battery pack to one or more application devices using an analog signal. The end device powered by the battery pack system receives and reacts to the outputted fully charged signal by modifying the state of the circuitry on the end device.

  • Patent number: 11411415
    Abstract: A charging apparatus includes a main body including a charging electrode for charging a robot cleaner, a sensing unit for sensing that the robot cleaner is docked to the main body, and the robot cleaner is electrically connected to the charging electrode, a power supply unit for supplying charging current to the charging electrode, a measuring unit for measuring the magnitude of the charging current provided to the robot cleaner, and a MICOM for recognizing whether the robot cleaner is docked based on information on the magnitude of the charging current measured in the measuring unit. When the measured magnitude of the charging current is less than the magnitude of a set current, the MICOM transmits a first setting signal to the robot cleaner, and based on whether a second setting signal corresponding to the first setting signal is received, the MICOM checks whether the robot cleaner has been docked.
