1. Brief introduction Communication LFP battery module is a high-tech product.The product many merits, mainly including: integration, miniaturization, light-weight, intelligent centralism monitoring, the battery maintenance and management, unattended, standardization installation and easy operation, at the same time, environment friendly. Now the product has been widely used as backup power in telecommunication field such as access network equipment, far-end telephone exchange,...
signal. When discharge voltage is below the protect parameter, the battery will automatically turn off. The battery module has fine electromagnetic compatibility. Fully intelligent design, equipped with centralized monitoring module and telemeters, telesignalisation, remote regulating, remote control function, realizes intelligent management, and can correspond with the far-end central monitoring center.
In order to satisfy Telecom Operator’s new demands on the power-supply system, developed the integrative backup battery module solution based on LFP battery, BM S, DC switch power module or ups (uninterrupted power system). Higher gravimetric specific energy, during installing, there is no extra demand for space and bearing compared with VRLA battery, greatly reducing the cost of the area rented.
