 2.5MW PV Charging System Case

项目简介 | Project Introduction

本项目为2.5MW光储充一体化智能充电站，由稳利达电力电子提供整体直流变换与充电系统解决方案。系统总功率2500kW，由10套250kW子系统并联构成，每套子系统配置9台30kW双向DCDC变换模块与1套双枪直流充电终端，全站共20把直流快充枪。光伏侧直流电经MPPT变换后直接供给电动汽车充电，实现"光伏发电—直流变换—车辆充电"**短能量链路，显著降低线损与变换损耗。系统配置10寸本地触摸屏与RS485远程通讯，支持遥控、遥测、遥调，具备完备的过压、欠压、过流、过温与通讯保护，运行稳定可靠。

This project is a 2.5MW PV-storage-charging integrated smart station, delivered by Wenlida Power Electronics as a complete DC conversion and charging solution. Total system power is 2500kW, composed of ten 250kW subsystems in parallel. Each subsystem is equipped with nine 30kW bidirectional DC-DC conversion modules and one dual-gun DC charging terminal, totaling 20 DC fast-charging guns across the station. DC power from the PV side is directly supplied to electric vehicles via MPPT conversion, achieving the shortest energy chain of "PV generation – DC conversion – vehicle charging" and significantly reducing line and conversion losses. The system features a 10-inch local touch screen and RS485 remote communication for telecontrol, telemetry and tele-adjustment, with comprehensive over-voltage, under-voltage, over-current, over-temperature and communication protections for stable and reliable operation.

整套系统配置10寸本地触摸屏，供客户监控数据并实现触摸操作；提供一路RS485接口，支持遥控、遥测、遥调功能。系统拓扑为单套250kW子系统，整个系统由10套子系统构成，共计2500kW。光伏侧直流电经DCDC模块MPPT变换后接入充电枪母线，双枪分别独立输出，支持GB/T 2015国标快充协议。

The system is equipped with a 10-inch local touch screen for on-site data monitoring and touch-based operation. One RS485 port is provided for remote telecontrol, telemetry and tele-adjustment. The topology is based on a single 250kW subsystem; the entire station consists of ten such subsystems totaling 2500kW. PV-side DC power is MPPT-converted by the DC-DC modules and fed to the charging-gun bus; the dual guns output independently and support the GB/T 2015 national fast-charging protocol.
