  • Battery pack remaining charge balancing system
    Patent number: 11923704
    Abstract: A computer implemented method includes accessing a first status of a first battery pack interface coupled to a load via a first load switch and accessing a second status of a second battery pack interface coupled to the load via a second load switch. The first status and the second status are compared and the first and second load switches are controlled based on the comparing to balance remaining capacities of the first and second battery packs.
    Type: Grant

  • Receive and transmit coil pair selection
    Patent number: 11646606
    Abstract: A machine implemented method includes alternately energizing multiple transmit coils in a first device, receiving indications of received signal strength at receive coils in a second device, selecting a first pair of coils including a first transmit coil and a first receive coil having the greatest received signal strength, and transferring energy from the first transmit coil to the first receive coil.

  • Devices, systems, and methods for temperature based limiting of battery pack discharge
    Patent number: 10418836
    Abstract: Systems and methods for limiting battery discharge based on battery temperature are disclosed. In an example, a controller sets a current limit, using battery temperature, and provides corresponding current limits to a power management device and a system-on-chip (SOC). Upon battery discharge current exceeding the discharge current limit, the controller increases the discharge current limit, and provides updated current limits to the PM device and the SOC. Upon the battery temperature exceeding a battery pack maximum temperature, the controller issues a shutdown command to the PM device and the SOC.
