A system for a boat includes a first guideway installed under a main deck of the boat, a first battery pack coupled to the first guideway under the main deck, and a first actuator configured to move the first battery pack along the first guideway. A controller is electrically and/or signally coupled with the first actuator. A user input device is electrically and/or signally coupled with the controller. The controller is configured to control the first actuator to move the first battery pack along the first guideway in response to an input to the user input device so as to relocate the weight of the first battery pack under the main deck.

System for distributing battery weight on a boat

A thermal management system for a marine vessel. The thermal management system includes an open loop circuit and a pump that pumps water from a body of water, through the open loop circuit, and back to the body of water. The thermal management system further includes a closed loop circuit and a pump that pumps a heat transfer fluid through the closed loop circuit. A heat exchanger is configured to exchange heat between the water and the heat transfer fluid. The thermal management system includes multiple components each cooled or heated by the heat transfer fluid. A valve has valve positions configured to vary a sequence that the heat transfer fluid is conveyed to the components so as to vary how the components share the heating and cooling from the heat transfer fluid and from the water from the body of water via the heat transfer fluid.

Thermal management systems and methods for thermally managing components for marine vessels

A marine battery pack including an enclosure defining a cavity, a plurality of cell modules within the cavity, each comprising a plurality of battery cells, and at least one sensor configured to sense at least one of a temperature, a pressure, a presence of water, and a gas content within the cavity. A controller is configured to detect an event warranting decommission of the battery pack based on the temperature, the pressure, the presence of water, and/or the gas content within the cavity, and then to automatically operate a pump to intake water from outside of the enclosure and pump water through the cavity from an inlet port in the enclosure to an outlet port in the enclosure so as to cool the plurality of battery cells.

Marine battery safety system and method

A system for draining a cooling system of a power generation system on a marine vessel includes a pump in fluid communication with the cooling system, the pump actively removing cooling water from the cooling system. An outlet drain discharges the cooling water. A controller starts the pump in response to an operator command to stop a prime mover of the marine power generation system and/or a speed of the prime mover being below a threshold speed. In one example, a temperature sensor determines a temperature of the cooling water in the cooling system, and the controller stops the pump in response to the temperature of the cooling water exceeding a threshold temperature. In another example, a sensor determines a pressure and/or a level of the cooling water in the cooling system, and the controller stops the pump in response to the pressure and/or the level of the cooling water dropping below a threshold pressure or a threshold level, respectively.
