Description

A Charging System for Preventing a Fire of an Electric Vehicle and a Method for Preventing a Fire of an Electric Vehicle by the Same The present invention relates to an electric vehicle fire prevention charging system and a fire prevention method using the same. Specifically, it relates to an electric vehicle fire prevention charging system and a fire prevention method using the same that monitors various parameters capable of detecting fire during the charging process to prevent fires that may occur during the charging process. Electric vehicles require a significant amount of charging time, making it difficult to monitor the charging process directly with the naked eye. Therefore, the charging process of electric vehicles needs to be monitored automatically, and various means for such automatic monitoring must be installed at chargers or charging stations. For example, it is necessary to automatically monitor whether charging is proceeding under specified voltage or current conditions, or whether there is leakage current, and to take appropriate measures based on the monitoring results. However, fire risks that may arise from various causes during the charging process are difficult to detect automatically, and separate monitoring means need to be developed. In this regard, Patent Registration No. 10-2397479 discloses an electric vehicle charger fire detection system and method using a light-receiving lens and a detection sensor. Additionally, Patent Registration No. 10-2336030 discloses an electric vehicle fire detection and status anomaly prediction system. Since fire risks in electric vehicles can arise from various causes, it is advantageous to monitor them in real time and transmit various risk factors generated during the charging process to the electric vehicle owner in real time. However, the prior art does not disclose methods or means for this purpose. The present invention aims to solve the problems of the prior art and has the following objectives.
