ABSTRACT:
A dual battery backup system which provides power to selected portions of a trip recorder according to a load shedding strategy to maximize duration of operation and data retention in the event of interruption of primary power supply. The trip recorder is divided into three subsystems; a central processing unit, input/output and memory/clock subsystems. In the event of interruption of power from the vehicle battery, backup power is supplied to all systems according to a load shedding strategy. Power supplied to the input/output subsystem and the central processing unit are interrupted after the passage of predetermined amounts of time. The memory subsystem receives power after all other subsystems have been shed enabling memory retention for a period of up to ten years.
