Certain embodiments of the present invention relate to a dynamic power
management system. The system includes a power input providing power to
an imaging system, measurement unit(s) for measuring current and/or
voltage in the imaging system, and a power management controller
allocating available power among components in the imaging system. The
power management controller may allow a battery to charge at a maximum
rate based on current used by the imaging system components. The
measurement unit(s) may measure a voltage and a current for the power
provided to the imaging system. The power management controller may
control current drawn by the imaging system components. The system may
also include a limit sensor for detecting when current consumption
exceeds a certain limit. Additionally, the system may include at least
one switching unit controlled by the power management controller. The
switching unit(s) control an amount of power routed to imaging system
components.
