Here is the professional English translation of your text regarding the ECE R136 standard:
Main Test Items under ECE R136 Regulation:
Vibration Test: Simulates the vibration environment encountered by vehicles during driving to ensure the performance and safety of the battery system under such conditions.
Thermal Shock Cycling: Tests the battery system's resistance to rapid temperature changes, ensuring performance and safety under extreme thermal fluctuations.
Drop Test: Simulates accidental drops of the battery system to evaluate structural integrity and safety.
Mechanical Shock Test: Assesses the safety performance of the battery system when subjected to mechanical shock.
Fire Resistance Test: Verifies the flame-retardant capability of the battery system, ensuring sufficient evacuation time for passengers in the event of an external fire.
External Short Circuit Protection Test: Validates the protective functions of the battery system against external short circuits to prevent severe subsequent incidents.
Overcharge Protection Test: Ensures the battery system possesses overcharge prevention features to avoid safety issues caused by excessive charging.
Over-discharge Protection Test: Verifies the protection function of the battery system when discharged to an excessively low level, preventing battery damage.
Overtemperature Protection Test: Evaluates the battery system's ability to prevent internal overheating in the event of cooling system failure.
Battery systems certified under ECE R136 are permitted for sale in the European market and are recognized by all European countries. This certification is crucial for battery manufacturers and electric vehicle producers aiming to enter the European market. Laboratories conducting these tests must possess the necessary qualifications and equipment to ensure the accuracy and authority of the test results. A battery system that passes ECE R136 certification is awarded the E-mark, which serves as a vital proof of compliance with European safety standards
