System and method for supplying power to communication base station through new energy vehicle

Abstract

The invention reveals a system and method for supplying power to a communication base station through a new energy vehicle, and the system comprises the new energy vehicle, a power supply unit and the communication base station. The new energy vehicle, the power supply unit and the communication base station are connected sequentially. The new energy vehicle comprises a vehicle-mounted battery and a BMS (battery management system), wherein the vehicle-mounted battery is connected with the BMS. The power supply unit comprises a protocol conversion unit, a slow start unit, a V / I monitoring unit, a real-time charging unit, a DC / DC unit, and a control management unit. The communication base station comprises a base station battery and a power environment monitoring system. The vehicle-mounted battery is connected with the slow start unit, and the DC / DC unit is connected with the slow start unit, the V / I monitoring unit and the control management unit. According to the invention, the system and method enable a two-stage working mode of power supply (inversion and rectification) to be changed into a DC / DC single-stage mode of power supply, and greatly improves the efficiency. The system can achieve the protocol conversion and interconnection between a communication power supply 485 interface and a CAN interface of a vehicle, achieves the direct protocol hand-shaking, and improves the safety.

Description

technical field [0001] The invention belongs to the technical field of base station power supply, and relates to a base station power supply system, in particular to a system for using a new energy vehicle to supply power to a communication base station; meanwhile, the invention also relates to a method for using a new energy vehicle to supply power to a communication base station. Background technique [0002] With the development of mobile communications and the continuous deepening of China Tower's co-construction, sharing and integration of the base station facilities of the three major communication operators, each communication base station is not only three stations in one, but also the only communication facility in the area, which has risen to the The importance level of "super base station" and "VIP base station". Electricity is the "blood" of modern communication systems. Once there is a problem with the power supply, it will lead to a complete interruption of the...

AI Technical Summary

Problems solved by technology

[0007] (1) After multi-level inverter (DC / AC) and rectification (AC / DC) conversion, the power supply efficiency is only 75%, and the waste of electric energy is serious;

[0008] (2) New energy vehicles (electric vehicles) need to be retrofitted, and external inverters (DC / AC) need to be installed, which has higher costs and increased vehicle electrical risks;

[0009] (3) The power supply system of the base station and the BMS system of the vehicle work independently, making the operation and maintenance of the site very professional, and it is impossible to realize the convenient sharing of various electric vehicles;
