Strict testing for safety and reliability requirements with all-round testing items, high test criteria, top-ranking testing equipment (a national testing center has been established, which is now under qualification formalities);
23 strict tests on battery pack such as fire and hammer; mature and developed electric and structural safety for relieved use.
Excellent battery cell gene: Life under room temperature of over 6,000 cycles; storage life for over 15 years; at least twice of current levels of similar products；
Solid mechanical structure design: All mechanical vibration and shock test are with reference to the installation position on the complete vehicle and requirements in GB/T 2423.43-2008; advanced mechanical reliability analogue simulation plus almost three days of accelerated fatigue test verification to ensure a service life of over 8 years；
BMS active equalization for automatic maintenance of the battery system, which guarantees the consistency of the battery system within the life cycle, extends the service life and greatly reduce manual maintenance；
Advanced service life testing technologies. Compared with other enterprise generally conducting constant current charging-discharging testing, CATL establishes testing plan simulating actual operations according to the mileage and service life of the customer; the overall mileage and service life available for the battery pack are calculated with service life curve model based on the testing data.
To satisfy the demands of variant design for new energy vehicles based on traditional vehicles and reduce the limitation of space arrangement for parts of the complete vehicle to the greatest extent；
V-model product development mode: The product development starts from the customer requirements , based on system requirements, which is then gradually iterated to subsystems and parts. Design, verification and production are organized by levels and stages to guarantee integrity, reliability and safety of product development.
Wide battery cell use temperature ranging from -30℃ to 60℃; capacity at -20℃may be over 90% of normal temperature and capacity at -30℃ may be over 80% of normal temperature, about 10% higher than industrial average levels；
The battery pack is suitable for all-weather environments; the enclosure Protection Grade may be IP67; pressure balance and emergency discharge units are provided to satisfy requirements related to air transportation, changes in elevation and temperature, emergent safety accidents, etc.；
