Kituo cha Kuchukua Namba na Suluhisho ya Kutoa Bei: Mwongozo Wa Kamili
I. Aina za Charging Pile na Uchaguzi wa Teknolojia
Mtaani ya AC vs. DC Charging Pile
AC Slow Charging Pile (7-22kW)
Hadhi za Matumizi: Nyumba, ofisi, jamii ya wakazi (muda wa charging 6-10 saa).
Ufafa: Gharama chache (¥1,000 - ¥4,000 kwa kitu), upungufu mdogo wa battery, usanidi rahisi.
Mizigo: Nishati chache, haiwezi kusaidia matarajio ya charging haraka.
DC Fast Charging Pile (30-480kW)
Hadhi za Matumizi: Steshoni za charging zinazotumika kwa umma, barabara, vituo vya biashara (charging hadi 80% kwenye ~30 dakika).
Ufafa: Kutoa nishati kubwa (mfano, 120kW dual-gun pile), inasaidia charging ya magari mengi kwa pamoja.
Mizigo: Gharama kubwa (¥50,000 - ¥200,000 kwa kitu), inahitaji msaada wa kupanua uwezo wa grid.
Mizizi Muhimu ya Performance
Daraja la Protection: Lazima kiwe ≥ IP54 (ing'ombe na maji).
Ulinzi wa Usalama: Overvoltage/overcurrent/leakage/lightning protection, funkiya ya kutokomesha darura (inatimiza standardi GB/T 18487.2).
Matalabu ya Efficiency: Conversion efficiency ≥ 94%, power factor ≥ 0.98.
Uongozaji Smart: 4G connectivity, monitoring mbali, malipo ya APP (mfano, QR code/RFID card).

Seremoni za Uchaguzi:
Efficiency First: Chagua AC piles kwa nyumba; chagua DC piles kwa hadhi za umma.
Safety & Reliability: Lazima ipitishwe CQC/CNAS certification.
Scalability: Rejelea interfaces za expansion ya nishati (mfano, 400kW split-type pile inasaidia ongezeko la uwezo baadaye).
III. Mipango muhimu ya Implementation & Cost Optimization
Infrastrakti ya Nishati
Grid Connection: DC piles inahitaji voltage ya three-phase 380V; AC piles inahitaji voltage ya single-phase 220V.
Capacity Expansion Cost: Power modification for commercial scenarios can cost ¥100,000 - ¥500,000 (incl. transformer/cables).
Installation & Operation/Maintenance (O&M)
Wiring Specifications: Use cables ≥10mm² for DC piles, use 6mm² BV wire for AC piles.
O&M Cost: Annual maintenance cost is approximately 5%-10% of equipment value.
Serikali & Subsidies
Serikali za mitaa zinatoa madukani ya vifaa (mfano, kusambaza hadi 30% ya gharama) na bei nzuri za umeme kwa steshoni za charging za umma.
IV. Mwenendo wa Teknolojia wa Baadaye
Nishati Kubwa: >11kW home AC piles and 480kW split-type DC piles become mainstream, adapting to 800V high-voltage platform vehicles.
V2G Technology: Enables bidirectional power flow between vehicles and the grid, requiring charging piles to support smart scheduling protocols.
Centralized Flexible Charging: Split-type DC piles dynamically allocate power, improving utilization (e.g., 400kW power cabinet supports flexible output to 10 charging guns).
