Product catalog summary

Main Applications: The document outlines the primary applications for the battery technology, including renewable energy storage systems (wind and solar), peak shifting in electrical power systems, frequency regulation, smart-grid and micro-grid sites, and extreme environments such as off-grid and bad-grid sites.

Technical Parameters: The battery has a nominal voltage of 2V and a capacity of 300 Ah at 10 hours to 1.80 V at 25°C. It weighs 28.3 kg and has dimensions of 154 mm in length, 207 mm in width, and 358 mm in height. The internal resistance when fully charged is 0.28 mΩ, and it can handle a short-circuit current of 6400 A. The self-discharge rate is less than 7% after 90 days at 25°C.

Benefits: The battery technology offers exceptional fast charging acceptability, a long design life that reduces operating costs, ultra-high cycling performance in both PSoC and deep cycling, and super-fast charging performance that reduces charging time by 50%. It also offers less storage cost per kWh.

Technical Features: The battery adopts lead carbon technology to reduce sulphation of the cathode, making it ideal for PSoC cycle applications and delivering 7 to 8 times the cyclic life compared to normal VRLA batteries. It is designed for premium quality, high reliability, and stability.

Certifications: The battery is certified with ISO9001 (NO.03009Q10083R2M), ISO14001 (NO.03010E10145R0M), and GB/T28001 (NO.03010S10141 R0M).

Performance Characteristics: The document includes detailed performance curves and characteristics, such as constant current and power discharge characteristics at various voltages and times, self-discharge curves at different temperatures, and discharge performance at different rates at 25°C.

Environmental and Operational Conditions: The battery operates within a temperature range of -20°C to 45°C for discharge, charge, and storage. The recommended operating temperature is between 15°C and 30°C. The recommended charging current is 60 A, with a maximum charging current of 105 A.
