  • METHOD TO CONTROL MULTIPLE PARALLEL BATTERY PACKS
    Publication number: 20240227624
    Abstract: A method of operating a machine battery system having multiple battery packs connectable in parallel includes bringing a first battery pack with the highest offline pack voltage online for discharging, including a pack controller circuit of the first battery pack bringing one or more individual battery strings of the first battery pack online; bringing a next battery pack with a next highest offline pack voltage online when the next highest offline pack voltage is within a predetermined discharge threshold voltage of a load voltage, including the pack controller circuit bringing one or more individual battery strings of the next battery pack online; and waiting to bring the next battery pack online, when the next highest offline pack voltage is less than a predetermined discharge threshold voltage of the load voltage, until the next highest offline pack voltage is within the predetermined discharge threshold voltage.
    Type: Application
