Abstract
An RF asset tracking device for cargo containers that has an extended operational life, due to a power management system and multiple power sources. The device has a solar cell and high capacity supercapacitor as a principal power source and a rechargeable battery as an auxiliary power source. Control circuitries manage and regulate the usage of the primary and secondary sources. Together, these power sources provide sufficient power for the tracking device to operate for an extended period of time, thus increasing the period between needed maintenance and decreasing downtime and thus cost.
