"What used to take 10 hours can now be done in just 10 minutes. When this device is plugged into the fast charging port of an electric vehicle, we can know everything from battery stability to lifespan."
On the 6th, at the largest domestic battery exhibition 'InterBattery 2025' held at COEX in Gangnam, Seoul, Kim Ik-jeom, the Deputy Minister of MinTech, a company listed on the Korea Securities Dealers Automated Quotations (KOSDAQ) and a diagnostic company for electric vehicle batteries, explained the battery rapid diagnosis system.
MinTech's battery rapid diagnosis system is a device the size of a briefcase, fitting the definition of a portable device. When connected to a vehicle, information about the battery appears on a registered tablet.
The battery rapid diagnosis system is a portable diagnostic device that can determine the status of an electric vehicle battery without separating the battery pack from the vehicle body. Currently, maintenance companies or used car dealers must separate the battery pack from the vehicle body and connect it to equipment worth over 300 million won that charges and discharges the battery to determine capacity lifespan, charging status, output status, and balance status. This process takes about 10 hours.
However, MinTech's battery rapid diagnosis system does not require the battery to be separated from the vehicle body and can be diagnosed within 10 minutes, thanks to the 'electrochemical impedance spectroscopy (EIS)' that measures resistance by passing current through the battery.
Kim Ik-jeom noted, "If the inspection method based on EIS developed by MinTech becomes standardized in the electric vehicle market while battery diagnosis technology is still not commercialized, we can expect to see even greater benefits."
This product was co-developed by MinTech and the Korea Transportation Safety Authority, and they are also collaborating with domestic corporations H. The company foresees additional cooperation opportunities as the product is used in maintenance organizations under the Korea Transportation Safety Authority and H.
MinTech plans to launch the 'B-OnScope,' which can monitor the battery's status in real-time, within this year. Currently, MinTech is conducting a pilot operation of B-OnScope in collaboration with GS M-Biz, a mobile service company under the GS group. Drivers can know immediately if there is a problem with the battery through this service.
Officials from MinTech believe that the 'pre-performance evaluation system for electric vehicle battery removal' to be implemented by the government by the year after next will have a positive impact on the company. Once the system is in place, all battery manufacturers must distinguish reusable batteries when scrapping electric vehicles. Hong Young-jin, the CEO of MinTech, added, "The battery rapid diagnosis system will stand out more in the used car market."
Hong noted, "Excluding sales from the battery rapid diagnosis system, we expect sales to be between 40 billion and 45 billion won," and "we anticipate new orders to be around 60 billion won." However, he expressed that it is still too soon to predict the expected sales of the new products.
Meanwhile, participants agreed that the chasm in the electric vehicle market (temporary demand stagnation) would resolve naturally if the battery price, which accounts for 40% of electric vehicles, decreases. Hong remarked, "If parts prices decrease, making electric vehicles cheaper compared to internal combustion engine vehicles, the profitability for automobile companies will improve," adding, "As corporations flock to the profitable electric vehicle market, the chasm will be resolved."
He added, "The global market must move according to carbon neutrality plans, so the battery market will continue to grow."
