PRODUCT

“The fisherman’s friend at the early morning dark boat ramp.”

Announcing a novel solution for the wireless control of a vessel’s main battery banks. This solution checks all of the boxes!  It transfers also to the RV, collector, and street rod markets, as well as the marine market. The marine market is targeted towards trailer boats, tenders, and smaller center console type vessels.  In its present embodiment it is a stand-alone unit, perfect for the do-it-yourselfer to install.  It could also be sold into the OEM markets.  The solution is scalable; it can be made to control multiple banks, combinations, or just one bank.

The product has been through provisional patent status in the United States (#62205971), International Patent Cooperation Treaty opinion on patentability based on novelty, inventive step, and industrial applicability (PCT/US16/47171), and cleared the US national stage of patent prosecution with the USPTO.  A full U.S. Utility Patent was granted April 3, 2018.  U.S. Patent                   , with sixteen claims to the state of the art. The remaining term of the Utility Patent is until August 17, 2035.

The original unit is installed on my personal Boston Whaler and has functioned flawlessly for over three years.  The case has never been opened since installation. The vessel and unit are available at any time in the San Francisco Bay area for a sea trial demonstration.

I am seeking a company with a versatile product line looking to add an innovative new product.  If your company has a pipeline of allied products and has an aggressive growth plan, this may be the perfect addition to your product line.   The intellectual property and associated consulting is available for licensure or outright purchase. I would invite you to look over the product description, PowerPoint, and videos at our website:  www.morninglightmarine.com A traveling display unit is available that can be demonstrated at your location, at my expense, if desired.

MORNING LIGHT MARINE WIRELESS POWER CONTROL

Product Description

  • A wireless solution for control of the main power supply of small to medium sized boats.

  • Used to actuate multiple preset electrical devices on boat without having to board the vessel.

  • Cockpit lights, spreader lights, radios, electronics, blower, power tilt/trim can be powered up.

  • Increased security by instant one touch disconnect of all boat power, theft deterrent.

  • Long range wireless up to 500 ft. depending on installation.

Product Features

  • Wireless remote control of main vessel battery power supply via Key FOB.

  • Can be used with multiple battery bank configurations.

  • Does not interfere with manual battery disconnect switches on boat.

  • Retrofit on existing power supply with only four wires to install, easy DIY install.

  • OEM applicability.

  • Sealed ignition protected safe for bilge installation.

  • Manual over-ride feature.

  • Wireless control individually coded.

  • Ignition sense feature prevents accidental power disconnect if engine running.

  • Minimal current drain in “listen”mode (less than 10 nano amperes).

  • Switch relay requires no current to maintain on or off status.

  • Rated for 500 amperes momentary (30 sec.) and 100 amperes continuous load.

  • Key FOB controlled rather than Blue Tooth (range) or WiFi for ease of use (lack of WiFi many areas).

Connections

  • Device connects between existing battery control switch and existing boat power main.

  • Additional connection to ignition 12 vdc positive and to negative ground.

 

Working Description

A positive size 0 battery cable     from the existing battery switch     output connects to the line side of the main relay (R-1). A connection from the line side of the main relay supplies positive 12 vdc via a fused 3 ampere  supply      to a Pico relay     that is wired in a normally closed configuration.  In the closed mode power is passed to the wireless receiver    . This receiver controls a polarity reversing momentary 12 vdc circuit that feeds the main latching relay coil     . In operation, dependent on the polarity supplied by the wireless control relay, the main latching relay moves between open and closed positions. The load side     of the relay (R-1) is connected to the boat’s power main.  A 12vdc positive connection from the ignition(s)     to the coil of the Pico relay      causes the Pico relay to open, thus interrupting the current to the wireless receiver relay   . This prevents accidental disconnection of the boat’s power supply if the engine(s) is running. A negative common ground       ties the Pico relay     and the wireless receiver      to the boat’s negative ground. A manual over-ride switch       is connected from the line side to the load side of the main relay by size 1/0 cables to allow for manual bypass of the wireless control in the event of a failure of any part of the control system. The entire device is enclosed in a sealed weatherproof box with liquid tight stain relief fittings for all wires that penetrate the enclosure rendering it safe for wet locations or explosive environments.

 

When the boat’s existing battery disconnect switch      is in the off position all current to the wireless switch is also disconnected and the device is non-functional.  When the boat’s existing battery switch      is on the wireless receiver      is activated and listens for a Key FOB command. In listen mode the receiver consumes less than 10 nano amperes of current. When in momentary switching mode the receiver relay (R-1) consumes approximately 1.0 amperes of current, continuous coil current is 2.7 amp. No current is required to maintain the latching relay (R-1) in either the open or closed position. The Pico relay    is energized while the ignition is on and power is supplied during this time by the engine alternator supply.

 

Utilizing Peukert’s law, the current drain of 10 nanoampes estimated on a conservative one battery, group 27 lead acid flooded with a 100 AHr rating at full charge of 12.6 v, would discharge the battery below 10.6 volts in 26 weeks in “listen” mode. Passive or normal discharge rates for typical lead acid batteries, for the above battery, would be approximately 4% per week or 4 amps per week. To reach an 80% charge level would then take 5 weeks for passive self-discharge.Acknowledge that most boats have multiple batteries or banks that would significantly increase this “listen” discharge time. These calculations would indicate the device has minimal effect on battery discharge time.

 

Improvements to the State of the Art

  • Remote controlled battery disconnect switches already exist.

  • Wireless remote controlled battery disconnect switches already exist.

  • Remote controlled battery disconnect switches with manual over-rides already exist.

The primary improvement to the state of the art is to incorporate an ignition sense circuit to prevent accidental power disconnection from an inadvertent activation of a wireless control. This enhancement of the totality creates an inherently safer solution for the application intended.
