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.
