Detachable auxiliary power system
Detachable auxiliary power systems are disclosed. In some embodiments, the power system comprises a housing with a cavity, and a detachable portion configured to be received into the cavity. The detachable portion includes a power source such as a rechargeable battery, and may include additional electrical circuits to manage the charge and discharge of the battery. The housing includes a cable for electrically connecting the housing to an external electrical system, such as a vehicle electrical system. When the detachable portion is inserted into the housing, it is electrically connected to the cable, and so able to be charged from the external electrical system, and selectively provide power from the power source to the external electrical system, such as for jump-starting a vehicle.
1. A detachable auxiliary power system, comprising:
a housing, comprising:
a cavity;
a retaining mechanism; and
a first power connector disposed within the cavity;
a detachable portion, sized to fit within the cavity, the detachable portion comprising:
a power source,
a second power connector disposed so as to connect with the first power connector when the detachable portion is inserted into the cavity, and
power management circuitry electrically connected to the power source;
a sensor to verify the detachable portion is fully inserted into the housing; and
a power cable electrically connected to the first power connector, and adapted to be connected to an external electrical system;
wherein the power management circuitry is configured to selectively charge the power source from electricity received from the power cable.
2. The power system of claim 1 , wherein the power source is a Lithium-Ion or Lithium-Polymer battery.
3. The power system of claim 1 , wherein the power management circuitry is further configured to supply electricity from the power source to the power cable, and is selected to supply electricity from the power source by actuation of a button or switch.
4. The power system of claim 3 , wherein the electricity is supplied from the power source for a predetermined amount of time following actuation of the button or switch.
5. The power system of claim 1 , wherein the detachable portion is releasably retained in the cavity by the retaining mechanism.
6. The power system of claim 1 , wherein the detachable portion further comprises one or more signaling devices.
7. The power system of claim 6 , wherein one of the signaling devices comprises a plurality of flashing lights.
8. The power system of claim 6 , wherein the detachable portion further comprises a flashlight.
9. The power system of claim 8 , wherein the detachable portion further comprises at least one accessory power port.
10. The power system of claim 9 , wherein the at least one accessory power port is one of a USB port, a cigarette lighter port, and a wall socket.
11. The power system of claim 1 , wherein the external electrical system comprises a vehicle electrical system.
12. The power system of claim 1 , wherein the housing further comprises at least one mounting point for securing the housing to a substrate.
13. A detachable power pack, comprising:
a power source;
a power port;
power management circuitry electrically coupled to the power source and power port;
at least one auxiliary power port; and
at least one signaling device;
wherein the detachable power pack is configured to connect to a housing equipped with a socket to electrically connect to the power port, and
wherein the power management circuitry is configured to detect whether a jumper cable that detachably connects to the power port is incorrectly hooked up to a vehicle.
14. The detachable power pack of claim 13 , wherein the power source is either a lithium-ion or lithium-polymer battery.
15. The detachable power pack of claim 13 , wherein the power management circuitry is configured to selectively provide electricity from the power source to the power port.
16. The detachable power pack of claim 13 , wherein the at least one signaling device comprises a plurality of flashing lights.
17. The detachable power pack of claim 13 , further comprising a flashlight.
18. The detachable power pack of claim 13 , wherein the housing comprises a cavity, and the detachable power pack inserts into the cavity.
19. The detachable power pack of claim 13 , wherein the detachable power pack is configured to be retained to the housing by a latching mechanism.
