  • SYSTEM AND METHOD FOR DYNAMIC SWITCHING BETWEEN BATTERIES IN A DUAL BATTERY SYSTEM
    Publication number: 20230376099
    Abstract: A system and method for dynamically switching power supply in a dual battery system to minimize unbalanced wear levels in the primary and secondary batteries. If the operating temperature of the primary battery reaches a reliability temperature threshold but the operating temperature of the secondary battery is less than the reliability temperature threshold, the controller switches a primary battery indicator to designate the secondary battery as the primary battery. If the operating temperature of the primary battery and the operating temperature of the secondary battery exceed the reliability temperature threshold, embodiments may switch based on a time the operational temperature of the first battery is equal to or greater than the reliability temperature threshold and a time the operational temperature of the second battery is equal to or greater than the reliability temperature threshold.

  • System and method for dynamic switching between batteries in a dual battery system
    Patent number: 11755088
    Abstract: A system and method for dynamically switching power supply in a dual battery system to minimize unbalanced wear levels in the primary and secondary batteries. If the operating temperature of the primary battery reaches a reliability temperature threshold but the operating temperature of the secondary battery is less than the reliability temperature threshold, the controller switches a primary battery indicator to designate the secondary battery as the primary battery. If the operating temperature of the primary battery reaches a pre-shutdown temperature but the operating temperature of the secondary battery is less than the pre-shutdown temperature, the controller switches a primary battery indicator to designate the secondary battery as the primary battery. If a difference between the wear levels of the batteries exceeds a wear level difference threshold, the controller switches a primary battery indicator to designate the secondary battery as the primary battery.
