South Korea to tighten EV battery transparency rules
South Korea’s transport ministry has proposed rules that would require carmakers and sellers to disclose more details about EV batteries, including the manufacturer and country of origin, at the point of purchase.
The changes would amend two related laws, including the enforcement rules of the Motor Vehicle Management Act, and expand required battery disclosures to 10 items from six.
New public fields would include the battery maker, country of origin, product name, and manufacturing date, while current disclosures focus on specifications such as capacity and rated voltage.
The ministry also plans to raise penalties for missing disclosures to up to 10 million won (US$6,600) and tighten rules for revoking safety certifications after repeated defects within two years.
National Fire Agency data shows 334 EV battery fires in the year ending March 22, up from 270 in the prior 12 months.

🧠 Food for thought
Implications, context, and why it matters.
This rule fits into South Korea’s wider battery safety rules
- The disclosure rules arrive as South Korea moves from maker self-certification to mandatory, government-run EV battery safety certification, in force since February 2025 1.
- Officials are also rolling out a battery tracking system that gives each EV battery a unique ID number for lifetime monitoring, plus registration updates when a pack is replaced 1.
- High-profile fires pushed the government to act, including a Mercedes-Benz fire in Incheon tied to a battery from Chinese supplier Farasis (a battery manufacturer) and a separate lithium battery manufacturing plant fire in Hwaseong that killed 23 workers 2.
- A study of 148 documented EV fire cases in South Korea (2018–2024) reported statistically significant links between battery manufacturer and other fire characteristics 3.
Battery makers are becoming more visible to shoppers
- The change aligns with a global push for clearer supply chains, since Europe will require EV manufacturers to disclose battery suppliers to consumers starting in 2026 2.
- Hyundai, Kia, and BMW Korea have already started voluntary supplier disclosures after public pressure 2.
- This shift nudges battery firms, long focused on business-to-business sales, to build a reputation with car buyers 2.
- Consumer confidence has softened, alongside a 15% year-on-year drop in South Korea’s domestic battery-EV sales in the first half of the year 4.
