Lithium Iron Phosphate 218AH Large Aluminum Case

I. Excellent Electrical Performance

High-capacity design: The battery has a nominal capacity of up to 218Ah, which can store a large amount of electrical energy to meet the long-term power supply needs of various high-energy-consuming equipment and systems.

Whether it is large-scale energy storage power stations or electric vehicles, it can provide stable and long-lasting power support.
Stable voltage platform: The nominal voltage is 3.2V, and the working voltage range is 2.5V - 3.65V. It can maintain a relatively stable voltage output during charging and discharging, providing a stable working voltage for electrical equipment, reducing damage to equipment caused by voltage fluctuations, and prolonging the service life of equipment.
Low internal resistance characteristics: The battery has extremely low AC impedance resistance, with a typical value ≤ 0.28mΩ (slightly different under different working conditions).

Low internal resistance means that during charging and discharging, the internal energy loss of the battery is small, enabling fast charging and discharging, improving energy conversion efficiency, and reducing the risk of heat generation. Even under high-current charging and discharging conditions, it can operate efficiently and stably.
Wide temperature range adaptability: The charging temperature range is 0℃ - 45℃, and the discharging working temperature range is -20℃ - 55℃.

This wide temperature adaptation range allows the battery to work normally under various harsh environmental conditions, whether it is the cold winter in the north, the hot summer in the south, or the plateau areas with large temperature differences, it can stably output electrical energy and ensure the normal operation of equipment.

II. Excellent Cycle Life and Reliability

Long cycle life: After rigorous testing, the cycle life of the battery is ≥ 6000 times (under standard charging and discharging conditions, with 80% DOD deep discharge as the test benchmark).

This means that during long-term use, the battery can withstand a large number of charge-discharge cycles while maintaining good performance, greatly reducing the frequency and cost of battery replacement, and providing users with a long-term stable energy storage solution.
High reliability: CATL's advanced production technology and strict quality control system ensure that each battery has extremely high consistency and reliability. From the selection and procurement of raw materials, to the precise manufacturing in the production process, to the all-round inspection of finished products, every link is strictly controlled to ensure that the battery can operate stably under various complex working conditions, reduce the probability of failure, and provide users with reliable energy guarantee.

III. Ultimate Safety Performance

Lithium iron phosphate chemical system: It adopts lithium iron phosphate (LiFePO4) chemical system, which has extremely high thermal stability and chemical stability. Compared with other lithium battery chemical systems, lithium iron

phosphate batteries have a very low risk of safety accidents such as thermal runaway, fire, and explosion under abnormal conditions such as overcharge, over-discharge, and short circuit, fundamentally ensuring the safety during use.

Multiple safety protection designs: The battery integrates a variety of safety protection mechanisms, such as overcharge protection, over-discharge protection, over-current protection, short-circuit protection, and temperature protection.

When an abnormal situation occurs in the battery, these protection mechanisms can respond quickly, automatically cut off the circuit or take other protective measures to prevent further damage to the battery and ensure the safety of personnel and equipment.

IV. Wide Range of Application Fields

Energy storage systems: In renewable energy power generation systems such as solar and wind energy, the battery can be used as an energy storage unit to store excess electrical energy and release it when the energy supply is insufficient, playing a role in peak shaving and valley filling, stabilizing power output, and improving the utilization efficiency and stability of renewable energy. At the same time, it is also suitable for grid-side energy storage power stations, helping the grid adjust peak-valley differences and improving the power supply quality and reliability of the grid.

Electric vehicles: With its high capacity, long cycle life and excellent safety performance, CATL's lithium iron phosphate 3.2V 218Ah battery has become an ideal choice for electric vehicle power batteries. It can provide strong and long-lasting power for electric vehicles, extend the cruising range of vehicles, reduce the number of charges, improve the user's driving experience, and help the development of the electric vehicle industry.

Other fields: It is also widely used in various electric vehicles such as electric forklifts, electric golf carts, and electric ships, as well as in fields such as communication base station backup power supplies, emergency lighting systems, and UPS uninterruptible power supplies, providing stable and reliable power support for these equipment and meeting energy storage needs in different scenarios.

CATL's lithium iron phosphate 3.2V 218Ah battery brings reliable, efficient and safe solutions to the energy storage field with its excellent electrical performance, outstanding cycle life, ultimate safety performance and wide application adaptability. Whether in large-scale energy storage projects, or in various electric vehicles and backup power fields, it has shown strong advantages and potential, and is your trustworthy energy storage partner.
