An electric vehicle charging system comprising:
- a charger for an electric vehicle;
- a fire detection device including a temperature sensor and a gas detection sensor to detect a fire in an electric vehicle charging space for the electric vehicle;
- a frame of the electric vehicle charging space;
- a fireproof cover configured to cover both side surfaces, a rear surface, and an upper end of the electric vehicle charging space based on the frame;
- a rollable door at a front of the electric vehicle charging space;
- a fire extinguishing device for the electric vehicle charging space;
- a warning output device including a visual warning device and an auditory warning device;
- a transceiver;
- a memory;
- and
- a processor functionally connected to the charger, the fire detection device, the rollable door, the fire extinguishing device, the warning output device, the transceiver, and the memory,
- wherein the memory stores instructions for operations performed by the processor, and the operations include:
- detecting, by the fire detection device, the fire in the electric vehicle charging space;
- outputting, by the warning output device, a warning of the fire;
- cutting off power supply of the charger;
- closing the rollable door;
- after closing the rollable door, spraying, by the fire extinguishing device, a fire extinguishing agent into the electric vehicle charging space,
- wherein information output by the warning output device includes a visual sign and an auditory sign indicating that the electric vehicle charging system is an origin of the fire,
- wherein the electric vehicle charging system is one of a plurality of electric vehicle charging systems in a parking lot including the electric vehicle charging system,
- wherein each of the plurality of electric vehicle charging systems has the same structure as the electric vehicle charging system,
- wherein the operations further include:
- transmitting a message notifying other electric vehicle charging systems included in the plurality of electric vehicle charging systems of detection of the fire in the electric vehicle charging system and a position of the electric vehicle charging system;
- generating, by the fire detection device, state information of the fire at a preset period until the fire is extinguished, wherein the state information includes an extent of occurrence of the fire or an extent of extinguishment of the fire after the spraying, by the fire extinguishing device, the fire extinguishing agent;
- determining fire response stage information of each of the other electric vehicle charging systems based on the fire state information at the preset period;
- transmitting the fire response stage information to the other electric vehicle charging systems at the preset period;
- and
- transmitting a message notifying a management terminal of the parking lot, a fire station terminal, and one or more user terminals registered in relation to the parking lot of the detection of the fire and the position of the electric vehicle charging system,
- wherein the fire response stage information includes warning stage information of the fire and response operations to be performed by each of the other electric vehicle charging systems in response to receiving the warning stage information,
- wherein the response operations include one or more of an operation of outputting a warning of the fire, an operation of cutting off power supply of the charger in each of the other electric vehicle charging systems, an operation of closing the rollable door, and an operation of spraying the fire extinguishing agent, and
- wherein, in each of the other electric vehicle charging systems, the warning of the fire is output based on the warning stage information,
- wherein the memory further includes arrangement information of the plurality of electric vehicle charging systems in the parking lot,
- wherein the warning stage information is generated based on a hierarchy according to a distance from each of the other electric vehicle charging systems to the electric vehicle charging system, and a floor difference,
- wherein the warning stage information includes visual warning information and auditory warning information,
- wherein, as a tier in the hierarchy determined for each of the other electric vehicle charging systems becomes higher, brightness and a blinking frequency of the visual warning information are increased, and a color of the visual warning information is changed, and
- wherein, as the tier in the hierarchy determined for each of the other electric vehicle charging systems becomes higher, a volume or a frequency of the auditory warning information is increased.
