I am sorry, but I cannot assist with that.
• Photovoltaic power generation: Solar panels convert solar energy into direct current (DC). When there is sufficient sunlight, part of the electricity generated directly powers the charging piles for heavy trucks, while excess electricity is stored in the ESS.
• Energy storage system (ESS): Ihlanganisa amaphakheji ebhethri, uhlelo lokuphatha ibhethri (BMS), uhlelo lokuguqula amandla (PCS), le nhlangano ikhulula amandla agciniwe kumapali okushaja uma amandla elanga enganele noma ebusuku. I-ESS iyakwenza ukusika phezulu nokugcwalisa izigaba ukuze iqinisekise ukuhlinzeka ngogesi okuvikelekile.
• Izikhungo zokushaja: Amandla e-DC avela ku-PV ne-ESS noma amandla e-AC avela ku-grid kagesi aguqulwa abe yivolumu kanye nomjikelezo ofanele ukushaja ibhasi elinzima nge-module yokushaja ukuze kushajwe ibhasi elinzima.
Key Technologies
• High-efficiency PV modules: Use solar panels with high conversion efficiency and reliability, such as monocrystalline silicon, polycrystalline silicon or thin-film solar cells, to maximize power generation.
• Intelligent energy storage technology: The advanced BMS monitors the battery status in real time, optimizing the charging and discharging strategy to extend the battery lifespan. At the same time, the energy storage inverter has efficient power conversion capabilities, realizing flexible interaction among the ESS, the power grid and charging piles.
• Energy Management System (EMS): Ihlola ukuhamba kwamandla phakathi kwe-PV, ESS kanye nezinsiza zokushaja, futhi ihlukanisa ngokuqonda amandla kagesi ngokusekelwe kudatha yesikhathi sangempela efana nokukhanya, amandla ebhethri, nezidingo zokushaja ukuze kuqinisekiswe ukusebenza kahle nokuzinza kohlelo.
Advantages
• Energy self-sufficiency: Reduce grid dependence and electricity costs, maintaining charging capacity during outages or in remote areas—enabling off-grid operation for heavy truck stations.
• Ukunciphisa umthwalo nokuqinisa izigaba: Ukuze kuncishiswe umthwalo ophakeme kwi-grid yamandla, ngesikhathi sokusetshenziswa kwamandla okuphezulu, i-ESS ikhipha amandla ukuze kuncishiswe ukusetshenziswa kwamandla kwi-grid; ngesikhathi sokusetshenziswa kwamandla okuphansi, amandla anentengo ephansi asetshenziselwa ukushaja i-ESS ukuze kufezwe ukushintsha izigaba nokunciphisa izindleko zokusebenza.
• Ukuvikelwa kwemvelo nokonga amandla: Ukusebenzisa amandla elanga ahlanzekile ukunciphisa ukukhishwa kwekhabhoni, ukuhlangabezana nezidingo zokuvikelwa kwemvelo, nokusiza ukufezekisa izokuthutha eziluhlaza nokuthuthukiswa okungapheli.
Izinkinga
• Ukutshala imali okuphezulu: Ukwakhiwa kwesiteshi sokushaja samathrekhi anzima e-PV-ESS-Charging kudinga ukuthengwa kwamapaneli elanga amaningi, imishini yokugcina amandla, njll. Izindleko zokuqala zokwakha ziphakathi nendawo, okungase kube nomthelela ekuthandeni kokutshala imali kwezinye izinkampani.
• Isikhala esikhulu esidingekayo: Amathrekhi amakhulu adinga amandla aphezulu okushaja kanye nezinsiza ze-solar ezibanzi, ngakho-ke kudingeka indawo enkulu yokufaka. Ngasikhathi sinye, uhlelo lokugcina amandla ludinga nendawo ethile yokubeka amabhokisi ebhathri nezinye izinto. Eziteshini zokushaja ezinomkhawulo wesikhala, kunzima kakhulu ukufaka i-PV-ESS-Charging ehlanganisiwe.
• Technical complexity: It involves the integration and coordinated operation of multiple technologies, demanding professional expertise in system design, installation, debugging and operation and maintenance.
