SEOUL—The uproar over a Mercedes-Benz electric vehicle that burst into flames in South Korea this month wasn’t only about fire safety. Outrage emerged over the lesser-known Chinese battery maker, Farasis Energy.
Now South Korea has a fresh proposal to ease public anxiety: advising carmakers to voluntarily divulge what brand of battery sits inside their EVs.
Such information isn’t generally public knowledge globally, despite the importance EV users place on battery life and driving range. At the same time, lithium-ion batteries—should they catch fire—burn at far higher temperatures than fires in conventional gas-powered cars and are uniquely challenging for firefighters to tackle.
It is rare for EV makers in the U.S. to disclose a car’s battery brand. The European Union last year approved the creation of a mandatory “battery passport” for EVs, which details the manufacturer and where the materials are sourced. It will take effect in 2027.
On Tuesday, South Korea’s top policy office for government ministries recommended that automakers provide more transparency about EV battery brands. The group plans to detail a comprehensive EV safety policy plan next month. In recent days, Hyundai Motor Co. , Kia Corp. , BMW Korea and Mercedes-Benz Korea have voluntarily disclosed on their websites who makes the batteries their EVs use.
