lifepo4 battery cells size

элементы аккумулятора lifepo4 имеет ряд уникальных преимуществ, таких как высокое рабочее напряжение, высокая плотность энергии, длительный срок службы, зеленая защита окружающей среды и поддерживает плавное расширение. После формирования системы хранения энергии ее можно использовать для крупномасштабного хранения электроэнергии. Система хранения энергии на основе литий-железо-фосфатной батареи состоит из литий-железо-фосфатной батареи, системы управления батареей (BMS), преобразовательного устройства (выпрямителя, инвертора), центральной системы мониторинга, трансформатора и т. д.

Moreover, lifepo4 battery cells supports stepless expansion and is suitable for large-scale energy storage. It has a good application prospect in the fields of power generation safety and grid connection of renewable energy power stations, peak regulation of power grid, distributed power station, UPS power supply, emergency power system and so on.

Electrical Characteristics

1、discharge capacity at normal temperature:After full charge, the experiment can be put on hold for 10 minutes; 0.5C discharge to 2.5V allows five repetitions. When the range of three consecutive experiments is less than 3% of the rated capacity, the experiment can be completed ahead of time and the maximum value of the test results can be obtaine。

2、Discharge performance at different temperatures:After standard charging of normal batteries, it should be stored at least 12 hours in the constant temperature environment of – 20 ℃, – 10℃, 0℃, 10 ℃ and 25 ℃, respectively, and 5 hours of 60 ℃. Then discharge with 0.5C current to the corresponding termination voltage. When the ambient temperature is more than 15 ℃, the termination voltage is 2.5V, if less than 15 ℃, which is 2.0V。
