Amid growing concerns about electric vehicle fires, global battery manufacturer LG Energy Solution has suggested that 'safety diagnostic software' is essential for preventing and diagnosing battery fires.
On the 2nd, Kim Hyun-jun, head of BaaS (Battery as a Service) at LG Energy Solution, stated at the policy forum titled "How to Respond to Electric Vehicle Fires" held at the National Assembly in Yeongdeungpo-gu, Seoul, "We hope a system will be established that mandates the safety diagnostic software function and sets standards for signs of safety concerns," adding, "Along with monitoring by the Battery Management System (BMS), which checks voltage, current, temperature, etc., it is now time to have software that can interpret this data and detect abnormal signs."
The battery safety diagnostic software analyzes various types of defects such as ▲voltage drop during charging ▲battery tab defects ▲micro internal short circuits ▲abnormal degradation ▲abnormal discharge ▲specific cell capacity deviation ▲excessive lithium deposition. LG Energy Solution holds more than 8,000 patents in the BMS field where safety diagnostic software is installed.
This forum was co-hosted by the offices of Jeong Jun-ho of the Democratic Party of Korea, Moon Jin-seok of the People Power Party, and the Consumer Sovereignty Citizens' Association.
At the forum, Hong Ki-chul, Executive Director of Battery Performance Development at Hyundai Motor Company, also emphasized the establishment of fire prevention systems such as BMS. Director Hong explained, "Through a three-stage safety design to prevent overcharging and detect abnormalities in electric vehicle batteries, fires that may occur during charging are fundamentally blocked," adding, "The BMS monitors battery status in real time and provides functions to immediately limit vehicle output or stop charging when abnormalities are detected."
He also stressed that the system continuously monitors battery status even while parked, minimizing fire risks not only during driving but also while the vehicle is stationary.
Professor Han Se-gyeong of the Department of Electrical Engineering at Kyungpook National University, who presented at the event, pointed out the need to build a platform to check electric vehicle battery information in real time. He emphasized the necessity of a control system that shares information with vehicle owners and fire authorities to respond promptly in case of abnormal situations.
Professor Han said, "Data-based early diagnosis is the most practical solution to prevent battery fires," adding, "It should be possible to diagnose the current state based on data from the cell level of the battery and control it if abnormal signs appear."
He further noted, "Collecting and managing data systematically at every stage from battery manufacturing to reuse to enable precise diagnosis of battery status is increasingly recognized as an essential element of the electric vehicle ecosystem in major countries."
Kim Seong-tae, president of the Korea Electric Vehicle Users Association, also stated, "The Battery Management System (BMS) function that notifies vehicle owners and fire authorities when there is an abnormality in the battery should be installed in all electric vehicles."
