  • Patent number: 10847835
    Abstract: A battery management system monitors and controls the state of charge of a plurality of battery cells with a single data transceiver line. A sense board coupled to each cell monitors the battery cell voltage and temperature and reports the cell voltage in series, according to the location in series. A data request signal is sent by the control device of the battery management system through the single data transceiver line to initiate battery cell data transmission. The first battery cell in the series sends the first battery data upon receiving the data request signal and each subsequent battery cell in the series sends their respective battery data after a predetermined delay time set by two quaternary bits formed by a pair of voltage dividers. The state of charge may be displayed in real time on a graphical or numerical display.

  • Patent number: 10797534
    Abstract: A wireless power transmission system has a wireless power receiving device that is located on a charging surface of a wireless power transmitting device. The wireless power receiving device has a wireless power receiving coil and the wireless power transmitting device has a wireless power transmitting coil array. Signal measurement circuitry coupled to the coil array may make measurements while the control circuitry uses the inverter circuitry to apply excitation signals to each of the coils. Foreign objects on the coil array such as metallic objects without wireless power receiving coils can be detected using foreign object detection. When multiple wireless power receiving devices are present on the wireless power transmitting device, steps may be taken to isolate measurements from the coils associated with each wireless power receiving device. Foreign object detection may then be performed on these modified measurements.
