The EU Battery Regulation (Regulation (EU) 2023/1542) applies in phases starting from 18 February 2024, covering all batteries entering the EU market, including those installed in products. The critical date is 18 February 2027: Light Means of Transport (LMT) batteries, industrial batteries with capacity of 2 kWh or above, and electric vehicle batteries must each have a "Battery Passport"—a digital dataset linked via QR code. E-bike batteries and electric scooter batteries fall under LMT batteries, directly applying to Taiwan's e-bike and battery module exporters.
