Production features

◆Using high voltage DC lithium-ion battery system for telecommunication power supply directly, Can be alternative UPS in the communication core room, Internet data center (IDC), DC remote power supply and other communications, Multi machine parallel become easy, Non harmonic interference, No inuence of 0.6 to 0.8 of the power factor, no phase and frequency and other issues, the real implementation of the backup power of the "0" switch;
◆High voltage DC lithium-ion battery system for telecommunication saves the inverter, power eciency increased from 70% to more than 95%, greatly reducing the operating costs;
◆The charging current limiting technology and the discharge current sharing technology of High voltage direct current lithium-ion phosphate battery system, can directly use the N+1 redundancy design, Low investment cost, cost-eective, to avoid the UPS synchronous weaver complex technical problems;
◆Centralized monitoring module using CAN bus and the SNMP simple network management protocol, Achieve computer management and telemetry, remote control, remote control, remote adjustment and other functions, Through the RS485, to accept HMI (man-machine
interface) query system all the information, as shown in Figure 3.Can be remote communication with the dynamic loop system;
◆4.0C discharge performance of high voltage direct current DC lithium-ion battery system, Can use the smaller capacity of the lithium-ion phosphate battery system to meet the use of large current discharge occasions, reduce the one-time investment cost of power equipment;
◆Working temperature range - 20℃~ + 60℃, by air instead of air conditioning, annual electricity saving more than 30%, greatly reduce the cost of equipment investment and daily electricity consumption;
◆More than 3000 cycles for individual cells;
◆Higher volumetric specic energy and gravimetric specic energy,during installing, there is no special demand for space and bearing, greatly reducing the cost of renting the area;
◆LFP cell adopts leakproof structure, it can be put anywhere with no harmful gas release, non-pollution, green product.
