The basic structure of the lithium iron phosphate power battery pack used in the base station of the computer room is shown in the figure below. The battery pack includes two parts: battery module and BMS.
(Basic structure of iron-lithium battery pack)
(1) Battery module
The specifications of Chineng lithium iron batteries are shown in the table below. For example, a 50Ah lithium Iron battery requires 16 cells with a single 3.2V battery. The battery of this model has a height of 4U and can be embedded in a machine room-less cabinet. A single battery pack can be used in parallel to form a larger capacity battery pack. For example, two groups of 50Ah battery packs can form a 100Ah battery pack.
2) Battery Management System (BMS)
BMS is mainly used to manage the battery charging and discharging process, improve the service life of the battery, and provide users with relevant information. BMS generally consists of monitoring, protection circuits, electrical, communication interfaces, thermal management devices, and other parts. Its main functions include intelligent charge management, battery balance management, intelligent intermittent charge, and discharge management, thermal system management, and communication management.
