Group 1 - The new national standard for electric vehicle power batteries will be implemented starting July 1 next year, focusing on enhancing safety measures to prevent battery fires and explosions [1] - The new standard includes additional testing items such as bottom impact tests and safety tests after fast charging cycles, aiming to improve consumer safety [1] - Testing institutions have increased their testing activities significantly, with some even introducing tests that are more stringent than the new national standard [1] Group 2 - The testing process involves simulating extreme scenarios, such as puncturing the battery pack from below with multiple steel needles, to assess the safety of electric vehicles under complex conditions [1] - The battery pack drop test simulates a scenario where the battery pack falls from a height of 3 meters onto a steel fixture, ensuring that it does not catch fire or explode [2] - Various testing methods, including whole vehicle fire tests and collision tests, are being conducted to validate the safety of electric vehicle batteries [2]
