Abstract
A power management system is provided to manage internal and external power sources for an embedded electronic device. The power management system includes an internal power source and an external power source. The power management system determines when to power the internal embedded electronic device or devices from either the internal or external power source, when to recharge the internal power source, when to shut down the internal embedded electronic device so as not to over discharge and damage the internal power source when external power is not available.
