Disclosed is a fire prevention and control system for a rechargeable battery cabin of a ship, including a detection apparatus, a fire suppression apparatus, and a control apparatus. The detection apparatus includes a first detection apparatus and a second detection apparatus, the control apparatus includes a first control apparatus and a second control apparatus, the first control apparatus is connected to the first detection apparatus, the second control apparatus is connected to the second detection apparatus, and the first control apparatus and/or the second control apparatus is configured to control whether the fire suppression apparatus releases a fire extinguishing agent. Beneficial effects: This application provides a fire prevention and control system for a rechargeable battery cabin of a ship. Detection apparatuses and control apparatuses are redundantly disposed, to provide high reliability of detection and high reliability of control, and implement a dual-path monitoring-control process of detection apparatus-control apparatus-fire suppression apparatus.

A battery pack includes at least one battery module; and a pack case including a pack tray having an open top and an internal space in which the battery module is received, and a pack cover coupled to top of the pack tray, wherein the pack cover includes a bottom cover having a valve mounting hole which is open in a preset region and disposed on the pack tray; a top cover having a flow channel region which forms a movement path of cooling water and disposed on an upper surface of the bottom cover; and a valve which is rotatably mounted in the valve mounting hole in a clockwise or counterclockwise direction, and configured to supply the cooling water in the flow channel region to the internal space of the pack tray or stop the supply.

A system for neutralizing embers is disclosed. The system includes a laser turret with a sensor array and a laser emitter configured to dispense laser energy. The laser turret can also include a control system configured to move the laser emitter. The laser control system can receive information from the sensor array and sending signals to the control system to move the laser emitter. Using these features, the laser control system can select an incoming ember based on a thermal signature associated with the incoming ember, and the laser control system can issue commands to the control system to direct the laser emitter towards the incoming ember, and the laser emitter can direct laser energy at the incoming ember. The system can also include provisions to track an ember and determine if an ember has been depleted of fuel.

The disclosure relates a control panel of a fire protection system, and a method thereof, having multiple smoke controllers. The smoke controllers correspond to zones of a facility. An alarm condition of the fire protection system is detected. An exhaust mode for a first smoke controller is entered, including activating exhaust effects and deactivating supply effects, in response to determining that an exhaust cause of the first smoke controller is active. A pressurize mode for a second smoke controller is entered, including activating the supply effects and deactivating the exhaust effects, in response to determining that an exhaust cause of the second smoke controller is non-active and a pressurize cause of the second smoke controller is active. The exhaust mode of the first smoke controller and the pressurize mode of the second smoke controller are maintained in a stable active mode.
