Abstract

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes a wireless control module having an internal power supply and an internal transceiver that receives commands from a remote control unit. A separate fuse module includes an outer housing and fuse blades that extend from the outer housing and interface with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The fuse module includes a fusible link, a relay controller and a relay in the outer housing. The fuse module receives power from and communicates with the wireless control module.

Claims

1. A system for remotely controlling the operation of at least one electrical subsystem that receives power from a vehicle battery through a fuse mounted within a fuse socket of a vehicle electrical system, the system comprising:

a control device having a transceiver for transmitting control commands;

a wireless control module including a first outer housing enclosing an internal power supply and a control module transceiver that communicates with the transceiver of the control device to receive the control commands;

a fuse module connected to the wireless control module to receive control signals from the wireless control module, the fuse module including a second outer housing surrounding a relay controller, a relay movable between an open position and a closed position based upon relay control commands from the relay controller, a plurality of fuse blades extending from the second housing and sized for receipt in the fuse socket of the vehicle electrical system, and a fusible link positioned between the fuse blades; and

a wired connection between the wireless control module and the fuse module such that the internal power supply provides power to the relay controller and the relay.

2. The system of claim 1 wherein the internal power supply is a battery.

3. The system of claim 1 wherein the relay is a latching relay.

4. The system of claim 1 wherein the wireless control module is in communication with both the control module transceiver and the relay to control the position of the relay based upon the received control commands from the control device transceiver.

5. The system of claim 1 wherein the control device is a smart phone.

6. The system of claim 1 wherein the self-contained fuse module includes either a three fuse blades or two fuse blades.

7. A wireless fuse switch for use with an electrical system of a vehicle having a vehicle battery connected to provide power to at least one electrical subsystem through a fuse contained within a fuse socket, the wireless fuse switch comprising:

a wireless control module including a first outer housing enclosing an internal power supply and a control module transceiver that receives wireless control commands;

a fuse module connected to the wireless control module by a wired connection to receive control signals from the wireless control module and to receive power from the internal power supply, the fuse module including a second outer housing;

a relay controller located within the second outer housing;

a relay located within the second outer housing, wherein the relay and relay controller are powered by the internal power supply;

a plurality of fuse blades extending from the second outer housing and sized for receipt in the fuse socket of the vehicle electrical system; and

a fusible link positioned within the second outer housing between the fuse blades.

8. The wireless fuse switch of claim 7 wherein the relay is a latching relay.

9. The wireless fuse switch of claim 7 wherein the relay controller is in communication with the control module transceiver and the relay to control the position of the relay based upon the received control commands.

10. The wireless fuse switch of claim 7 wherein the fuse module includes either three fuse blades or two fuse blades.

11. A wireless fuse switch for use with an electrical system of a vehicle having a vehicle battery connected to provide power to at least one electrical subsystem through a fuse contained within a fuse socket, the wireless fuse switch comprising:

a wireless control module including a first outer housing enclosing an internal power supply and a control module transceiver that receives wireless control commands;

a fuse module connected to the wireless control module by a wired connection to receive control signals from the wireless control module and to receive power from the internal power supply, the fuse module including a second outer housing;

a controller located within the second outer housing;

a switching device located within the second outer housing and movable between an open position and a closed position based upon command signals from the controller

a plurality of fuse blades extending from the second outer housing and sized for receipt in the fuse socket of the vehicle electrical system; and

a fusible link positioned within the second outer housing between the fuse blades.

12. The wireless fuse switch of claim 11 wherein the switching device is a latching relay.

13. The wireless fuse switch of claim 12 wherein the controller is in communication with the control module transceiver and the latching relay to control the position of the latching relay based upon the received control commands.

14. The wireless fuse switch of claim 11 wherein the fuse module includes either three fuse blades or two fuse blades.
