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 an internal transceiver that receives commands from a remote control unit and controls the position of an internal relay. The wireless control module interfaces 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 wireless fuse switch includes either a two-blade or three-blade harness assembly that allows the wireless fuse switch to be received within the fuse socket of the vehicle.

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 an internal power supply and a control module transceiver that communicates with the transceiver of the control device to receive the control commands;

a relay contained within the wireless control module and movable between an open position and a closed position based upon the received control commands; and

a harness assembly including a fuse connector that is received in the fuse socket to connect the relay to the fuse socket of the vehicle electrical system and a harness fuse socket that receives the fuse removed from the fuse socket, wherein the wireless control module includes a module connector that removably connects to the harness assembly.

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 includes a relay controller in communication with both the control module transceiver and the relay to control the position of the relay based upon the control commands.

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

6. The system of claim 1 wherein the harness assembly includes either a three-blade fuse connector or a two-blade fuse connector.

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 control module transceiver that receives wireless control commands;

a relay contained within the wireless control module and movable between an open position and a closed position based upon the received control commands;

a power supply contained within the wireless control module to power both the control module transceiver and the relay; and

a harness assembly including a fuse connector that is received in the fuse socket to connect the relay to the fuse socket of the vehicle electrical system and a harness fuse socket that receives the fuse removed from the fuse socket, wherein the wireless control module includes a module connector that removably connects to the harness assembly.

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 wireless control module includes a relay controller in communication with both 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 further comprising a two-blade harness assembly and a three-blade harness assembly, wherein the relay is connected to either the two-blade harness assembly or the three-blade harness assembly based upon the configuration of the fuse socket.

11. The wireless fuse switch of claim 10 wherein the module connector selectively connects the wireless control module to either the three-blade harness assembly or the two-blade harness assembly.
