CB safety certification for lithium batteries is based on IEC/EN 62133 testing standards. The test items are as follows:
Cell: low rate continuous charging, vibration, temperature cycle, external short circuit. free fall, impact (collision), thermal misuse (thermal shock), extrusion, low pressure, overload, forced discharge, high rate charge protection function (lithium system), labeling and packaging, incorrect installation (lithium system) nickel).
Battery: vibration, high temperature shell stress, temperature cycling, external short circuit, free fall, impact (collision), labeling and packaging, overload (nickel system).
I hope the above is helpful to you. If the answer is helpful to you or other passing friends, please accept and like it very much~
UN38 Battery. 3 and MSDS Test Report Differences
Duration Test Standardlithium battery life GB/T18287, IEC states that the standard lithium battery life test is: ?
The battery is discharged to 3.0 V at 0.2 C / After charging, charge with a constant current of 1 C and a constant voltage to 4.2 V with a cut-off current of 20 mA, leave it for 1 hour then discharge to 3.0 V with 0.2 C (a cycle). After repeated cycles 500 times, the capacity should be greater than 60% of the initial capacity.
The IEC states that the standard life test for nickel-cadmium and nickel-metal hydride batteries is: after the battery is discharged to 1.0 V/unit at 0.2 C. < /p>
According to the national standard for lithium batteries: GB/T18287-2000, the test items of lithium batteries include appearance, discharge performance, high and low temperature performance, capacity charge retention, life cycle life; vibration resistance and co resistancellisions, environmental adaptability with resistance to free fall; safety performance in overload protection, overvoltage protection and short circuit protection; safety performance in resistance to heavy object impacts, thermal shock, overload and short-circuit storage performance; etc. The following focuses on testing conditions and standards for discharge performance, high and low temperature performance, service life, and protection against overcharge, overdischarge, and short circuit.
1. Different references
1. UN38.3: Refers to the “United Nations Tests and Standards for the Transport of Dangerous Goods” specially formulated by the United Nations for the transport of dangerous goods. Part 3 of the manual, paragraph 38.3, requires that lithium batteries must passaltitude simulation, high and low temperature cycling, vibration testing, impact testing, external short circuit at 55°C, impact testing, overload testing and forced discharge testing before transportation. To ensure the safety of lithium battery transportation.
2. MSDS Test Report: This is a comprehensive regulatory document on the characteristics of chemicals that chemical production, trading and sales companies provide to downstream customers and the public in accordance with legal requirements. < p>2. Different requirements
1. UN38.3: High and low temperature impact test under conditions of 72±2℃ and -40±2℃, extreme temperature storage time ≥6h, high. and low temperature Conversion time ≤ 30 min, impact 10 times, keep at room temperature (20 ± 5 ℃) for 24 h, the total test time is at least one Zhou
2. MSDS Test Report: Provides 16elements, including physical and chemical parameters of chemicals, flammability and explosion properties, health hazards, safe use and storage, elimination of leaks, first aid measures and laws and relevant regulations.
3. Different symbols
1. UN38.3: In accordance with the requirements of civil aviation regulations, airlines and airport cargo collection and transportation services must review lithium battery transport documents. The most important thing is that each UN38.3 safety test report for each lithium battery model.
2. MSDS Test Report: The quality of MSDS is an important symbol to measure the strength, image and management level of a company. High-quality chemicals equipped with high-quality MSDS are bound to increase more business opportunities. .
