ISO 18243 is a standard for test specifications and safety requirements for lithium-ion battery systems for electric mopeds and Motorcycles. It specifies test procedures for lithium-ion battery packs and systems covering aspects such as performance, safety and Reliability. The test content includes Battery capacity, charge and discharge performance, temperature adaptability, overcharge and discharge protection, short circuit protection, etc., which aims to ensure the safety and Reliability of battery systems in vehicles. The standard also requires battery management systems (BMS) to have safety features such as overcharge and discharge protection, temperature protection, etc. ISO 18243 is suitable for manufacturers, suppliers, and testing organizations of electric mopeds and Motorcycles, providing uniform test methods and safety standards for the evaluation of battery systems.
