Battery emulator and methods of use
First Claim
1. A dynamic battery emulator for replacing the battery in a portable electronic device when the device is located in or on a vehicle having an electrical system, the dynamic battery emulator comprising:
- a power control module capable of varying its output voltage to adapt to the voltage requirements of an attached portable electronic device;
an input for conveying electrical power from the vehicle'"'"'s electrical system to the power control module;
an output for providing electrical power to the portable electronic device;
an output for communicating a control signal from the power adaptor to the portable electronic device to selectively turn on and off the portable electronic device;
a battery replacement module configured to replace the battery in a portable electronic device and comprising battery replacement circuitry for transferring electrical power from the power control module to the portable electronic device via the output for providing electrical power;
an ignition sense controller for determining the power state of the vehicle'"'"'s electrical system; and
in communication with the ignition sense controller, at least one timer and switch for reducing the conveyance of electrical power from the vehicle'"'"'s electrical system to the portable electronic device at a predetermined time after the vehicle'"'"'s ignition or electrical system is turned off;
wherein, when connected to the portable electronic device and the vehicle'"'"'s electrical system, the battery emulator provides electrical power to the portable electronic device of between 90-110% of the same voltage, impedance, current, and capacitance as the portable electronic device'"'"'s battery.

10. A method of controlling the on/off state and a controllable power supply of a portable electronic device connected to a vehicle in response to a trigger signal indicating that the vehicle has been turned on, wherein the portable electronic device turns on when the vehicle'"'"'s electrical system is powered on, and wherein the portable electronic device comprises a plurality of active call states including an idle call state and active call state, the method comprising the steps of:
-
turning on the portable electronic device; turning on the vehicle'"'"'s ignition, and thereafter turning off the ignition and starting a first timer in response to the turning off of the ignition; automatically instructing the portable electronic device to turn off if the first timer expires and the portable electronic device is in the idle or active call state; thereafter, determining whether the portable electronic device was last turned off in response to the timer expiring; thereafter, turning off the controllable power supply connected to the portable electronic device after the signaling to turn off the portable electronic device has occurred; thereafter, based on a determination that the portable electronic device was last turned off in response to the timer expiring, either; automatically turning on the controllable power supply attached to the portable electronic device in response to the vehicle'"'"'s ignition being powered on, the automatically turning on including supplying a control signal to the portable electronic device instructing the portable electronic device to turn on;
orleaving the portable electronic device turned off state if the vehicle'"'"'s trigger signal does not indicate that the vehicle has been turned on.

11. A method of controlling the on/off state of a portable electronic device connected to a vehicle trigger comprising the steps of:
-
monitoring the voltage of the vehicle'"'"'s trigger; automatically turning on a controllable power supply that emulates a battery attached to the portable electronic device, sending signaling to the portable electronic device to turn the device “
ON”
, and continually monitoring the device to make sure it is continually “
ON”
; andupon detection of the vehicle'"'"'s trigger turning off, initiating a timer to count down, wherein, upon expiration of the timer and the vehicle'"'"'s trigger staying “
OFF”
, the portable electronic device is sent a signal to turn it “
OFF” and
the controllable power supply is shut “
OFF”
;
whereinthe voltage measured from the vehicle'"'"'s trigger and the state of the portable electronic device are constantly monitored. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
