The present invention relates to a method and apparatus for preventing the spread of damage due to a fire in an electric vehicle charging station in a building parking lot in a communication system. Specifically, the present invention relates to a method and apparatus in which, when a fire is detected in one charging station of a plurality of electric vehicle charging stations installed in a building parking lot in a communication system, the charging station is closed, and a plurality of charging systems cooperate with each other to provide an optimal escape route as well as position information of the origin of the fire and a warning according to a fire situation, thereby minimizing the spread of damage and quickly responding to the fire.

There is described an actuator for a damper comprising an electrical circuit, a cable coupled to the electrical circuit, a lower housing supporting the electrical circuit, and an upper housing coupled to the lower housing. The electrical circuit controls positions of the damper. The cable provides power and control to the electrical circuit. The lower housing includes a first trough and a second trough to provide support for the cable in a first direction. The upper housing includes a first protuberance and a second protuberance to provide support for the cable in a second direction. The first and second protuberances are positioned offset from the first and second troughs of the lower housing.

A fire shutter control system and a fire shutter control method capable of effectively controlling a fire shutter in the event of a fire in a building are provided. The fire shutter control system may include a fire detector configured to detect a fire outbreak and generate a fire signal in the event of a fire; a fire shutter controller configured to apply a control signal to a fire shutter to enable a drive motor for operating the fire shutter to operate when the fire signal is generated by the fire detector; and a power supply unit configured to supply power to the fire detector, the fire shutter controller, and the drive motor for operating the fire shutter.

A fire and/or smoke curtain includes a roller, a fire and smoke curtain, and a retaining mechanism. The mechanism comprising an end plate for holding an end of the roller, a brake disc attached to the end of the roller. A connector attaches to the brake disc, the connector having a hook or ring element attached to a release mechanism comprising a lock element secured to the end plate at a proximal end, having a stop at its distal end and provided with a hook element onto which the hook or ring element of the connector is fitted, sliding lock element adapted to slide along a fixed plate, from a secure position in which the sliding lock is adapted to hold the hook or ring, and a release position, in which the hook or ring is released, releasing the brake to allow rotation of the roller and deploy the curtain.

The present invention discloses a thermal runaway monitoring and early warning system and method for a power lithium ion battery in a transport case. The system includes a monitoring unit, a data processing unit, a data transmission unit, a power supply unit, a display unit, and the like. The monitoring unit contains infrared array temperature sensors, gas sensors, smoke sensors, and pressure sensors, which are arranged using a distributed scheme to monitor the inside of the transport case. The data transmission unit sends early warning information to a terminal. According to a multi-information monitoring-based thermal runaway early warning method under different transport conditions, different transport condition data and data of the battery in the transport case are fused. A clustering algorithm and an ensemble learning algorithm are involved, and a lithium ion battery thermal runaway risk level is quantified, thereby improving the early warning accuracy.

A battery safety monitoring system includes a central controller, a fault detection sensor, a flame detection apparatus, and a fire extinguishing apparatus. The fault detection sensor is configured to detect a fault in a target battery module and send fault information to the central controller. The central controller is configured to control the flame detection apparatus to perform flame detection on the target battery module based on the fault information. The flame detection apparatus is configured to send, when detecting a fire in the target battery module, fire information to the central controller. The central controller is further configured to control the fire extinguishing apparatus to start a fire extinguishing operation for the target battery module. There is no need to deploy excessive sensors. Instead, the flame detection apparatus is controlled to perform flame monitoring on the target battery module, to implement low-cost and accurate battery safety monitoring.

A generator enclosure for an engine-generator includes multiple walls defining at least one air path. In one example, a first wall includes an exhaust path for the engine-generator, and a second wall includes an intake path for the engine-generator. The generator enclosure may include at least one air flow frame associated with the exhaust path or the intake path and at least one movable wall supported by the at least one air flow frame. At least one thermal fuse may be coupled to the at least one movable wall and configured to release the at least one movable wall to block the exhaust path or the intake path.

An upright sprinkler is disclosed. The sprinkler comprises a housing having a conduit extending therethrough, a heat-sensitive valve assembly configured above the conduit, and a nozzle arrangement configured below the conduit. The nozzle arrangement is fluidically connected to the conduit via the valve assembly, such that actuation of the valve assembly enables the flow of a fluid from the conduit to the nozzle arrangement via the valve assembly and further sprays the fluid at different downward-facing angles through the nozzle arrangement.
