DESCRIPTIONS OF THE PREFERRED EMBODIMENTS

[0017] Referring to the drawings and first to FIG. 1, there is shown a marine vessel 10 which is provided with a plurality of propulsion units which, in this example, are in the form of three outboard engines, namely, a port engine 12, a center engine 14, and a starboard engine 16. However, the propulsion units may be any number or form of propulsion units in other examples. The marine vessel 10 is also provided with a control station 18 that supports a steering wheel 20 mounted on a helm 22, a control head 24, and a joystick 26. The control station 18 is conventional and allows the port engine 12 and the starboard engine 16 to be steered using either the steering wheel 20 and the helm 22 or the joystick 26 as disclosed in PCT International Application Publication Number WO 20131123208 A1 which is incorporated herein by reference. The control station 18 further includes a first display interface 28 and a second display interface 30. In this example, the first display interface is a SIMRAD display interface which displays navigational information and the second display interface is a BEP display which displays onboard system information.

[0018] The marine vessel also includes a compact integration of digital distribution, analog distribution and battery management systems, namely, a battery management system 40 as part of a compact integration of which may be disposed in any suitable location on the marine vessel 10. The battery management system 40 is shown in greater detail in FIG. 2. The battery management system 40 includes a housing 42 which, in this example, has a bottom wall 44, a top wall 46, a first side wall 48, a second side wall 50, a third side wall 52, and a fourth side wall 54. The bottom wall 44 of the housing 42 is configured to be mounted to the marine vessel 10 and allows the battery management system 40 to be seated without shorting electrical circuits. The top wall 46 of the housing 42 is a hinged cover of the housing which allows access to an interior 56 of the housing which is shown in FIGS. 3. The interior 56 of the housing 42 may be sealed when the housing is covered. The housing may also be water resistant and/or fire resistant.

[0019] Referring to FIGS. 3A and 3B, the bottom wall 44 of the housing 42 has an interior mounting surface 60 and the top wall 46 has an interior mounting surface 62. The first side wall 48 of the housing 42 is a front of the housing and has an interior mounting surface 64 and an exterior mounting surface 66. The second side wall 50 of the housing 42 is a port side of the housing and has an interior mounting surface 68 and an exterior mounting surface 70. The third side wall 52 of the housing 42 is a starboard side of the housing and has an interior mounting surface 72 and an exterior mounting surface 74. The fourth side wall 54 of the housing 42 is a back of the housing and may be configured to be mounted to the marine vessel 10. The fourth side wall 54 of the housing 42 also has an interior mounting surface 76 and an exterior mounting surface 78. Electrical components are mounted on the interior mounting surface and the exterior mounting surfaces.

[0020] There are electrical components, for example a battery disconnect switch 80, mounted on the interior mounting surface 64 of the first side wall 48 of the housing 42 as shown in FIG. 3. There are also electrical components, for example a battery switch 82, a rocker type circuit breaker 84 and an LED indicator 86, mounted on the exterior mounting surface 66 of the first side wall 48 of the housing as shown in FIG. 4. There are electrical components, for example an electrical relay 88, mounted on the interior mounting surface 68 of the second side wall 50 of the housing 42 as shown in FIG. 3. There are also electrical components, for example a digital switching component 90, mounted on the exterior mounting surface 70 of the second side wall 50 of the housing 42 as shown in FIG. 5. There are electrical components, for example an feed through connector 92, mounted on the interior mounting surface 72 of the third side wall 52 of the housing 42 as shown in FIG. 3. There are also electrical components, for example an exterior 94 of the feed through connector 92, mounted on the exterior mounting surface 74 of the third side wall 52 of the housing as shown in FIG. 6. There is also cabling 96 which allow the battery management system 40 to be electrically connected to an electrical system of the marine vessel 10. There are electrical components, for example an electrical relay 98, mounted on an interior mounting surface 76 of the fourth side wall 54 as shown in FIG. 3. Electrical components mounted on the interior mounting surfaces are protected from foreign elements which allows for the use of components with lower corrosion resistance. Electrical components mounted on the exterior mounting surfaces allow for user interaction such as switching between modes and monitoring the status of the battery switches.

[0021] There may also be electrical components, for example wiring 100, mounted on the interior mounting surface 60 of the bottom wall 44 as shown in FIG. 3. There may also be electrical components, for example wiring 102, mounted on the interior mounting surface 62 of the top wall 46 of the housing 42 as shown in FIG. 3. Electrical components may also extend though the side walls. FIG. 4 shows the feed through connector 92 extending through the third side wall 52 of the housing 42 and FIG. 6 shows the battery switch 82 extending through the first side wall 48 of the housing 42. This allows for shorter wire routing to reduce resistance.

[0022] FIG. 7 is a schematic of an electrical system 200 of the marine vessel 10 showing the communication between the battery management system 40 the first display interface 28 and the second display interface 30. The battery management system 40 disclosed herein centralizes all electrical components in a single location to allow for easy installation, troubleshooting and maintenance of the electrical system 200 of the marine vessel 10. The pre-wired nature of the battery management system 40 reduces the risk of incorrectly configured electrical circuits.

[0023] In other examples, the housing of the battery management system may not have a bottom wall and the housing of the battery management system may be mounted to a surface of the marine vessel, for example the deck of the marine vessel, with said surface of the marine vessel functioning as the bottom wall of the housing of the battery management system. Alternatively, a side of the housing of the battery management system may not have a side wall and the housing of the battery management system may be mounted to a surface of the marine vessel, for example a bulkhead of the marine vessel, with said surface of the marine vessel functioning as the side wall of the housing of the battery management system.

[0024] It will be understood by a person skilled in the art that many of the details provided above are by way of example only, and are not intended to limit the scope of the invention which is to be determined with reference to the following claims.
