Smart power outlet system
View Patent ↗A smart power outlet system for a vehicle has a power outlet control module and a plurality of power outlets. Each power outlet has an associated set of power switching devices with each power switching device of a set of power switching devices coupled to a different power source. The power outlet control module drives a display and is responsive to user input via the display. The power outlet control module energizes one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user.
1. A smart power outlet system for a vehicle, comprising:
a power outlet control module;
a plurality of power outlets, each power outlet having an associated set of power switching devices, each power switching device of a set of power switching devices coupled to a different power source;
the power outlet control module driving a display and responsive to user input via the display;
the power outlet control module energizing one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user; and
wherein each power outlet is coupled in series to its associated power switching devices through a resettable circuit protection device, the power outlet control module monitoring the state of each resettable circuit protection device and displaying on the display whether any of the resettable circuit protection devices is tripped.
2. The smart power outlet system of claim 1 wherein the power outlet control module is responsive to a user command entered by a user on the display to reset any of the resettable circuit protection devices that have been tripped.
3. The smart power outlet system of claim 2 wherein the power switching devices are relays.
4. The smart power outlet system of claim 2 wherein the relays are latching relays.
5. A smart power outlet system for a vehicle, comprising:
a power outlet control module;
a plurality of power outlets, each power outlet having an associated set of power switching devices, each power switching device of a set of power switching devices coupled to a different power source;
the power outlet control module driving a display and responsive to user input via the display;
the power outlet control module energizing one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user; and
wherein the power switching devices are high side drivers and when a power switching device is to be energized to couple one of the power outlets to a power source that is not a power source provided when an engine of the vehicle is on, the power outlet control module monitors whether a load is plugged into that power outlet and energizes that high side driver only when the load is plugged into that power outlet.
6. The smart power outlet system of claim 5 wherein the power outlet control module monitors the state of each power outlet and displays on the display whether a high side driver in the set of power switching devices associated with that power outlet has experienced an overload condition.
7. The smart power outlet system of claim 6 wherein the power outlet control module is responsive to a user command entered by a user on the display to reset power to any power outlet having a high side driver in the set of power switching devices associated with that power outlet that experienced an overload condition.
8. A smart power outlet system for a vehicle, comprising:
a power outlet control module;
a plurality of power outlets, each power outlet having an associated set of power switching devices, each power switching device of a set of power switching devices coupled to a different power source;
the power outlet control module driving a display and responsive to user input via the display;
the power outlet control module energizing one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user: and
wherein the power switching devices are high side drivers and the power outlet control module monitoring current flowing through each high side driver that has been energized and de-energizing any such high side driver in the event that it experiences an overload condition.
9. A smart power outlet system for a vehicle, comprising:
a power outlet control module;
a plurality of power outlets, each power outlet having an associated set of power switching devices, each power switching device of a set of power switching devices coupled to a different power source;
the power outlet control module driving a display and responsive to user input via the display;
the power outlet control module energizing one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user; and
wherein the power sources include a battery of the vehicle, power provided when an ignition switch of the vehicle is in an accessory position and power provided when the ignition switch is in an on position.
10. A smart power outlet system for a vehicle, comprising:
a power outlet control module;
a plurality of power outlets, each power outlet having an associated set of power switching devices, each power switching device of a set of power switching devices coupled to a different power source;
the power outlet control module driving a display and responsive to user input via the display;
the power outlet control module energizing one of the power switching devices in each set of power switching devices corresponding to a power source selected by a user via the display to provide power to the power outlet associated with that set of power switching devices from the power source selected by the user; and
wherein the power outlet control module displays on the display a menu in the form of a visual representation of a vehicle showing a location of each power outlet in the vehicle.
11. The smart power outlet of claim 10 wherein a user can select each power outlet by touching its location on the menu and the power outlet control module then displays commands on the vehicle by which the user can select to reconfigure or reset that power outlet control module.
