Trasformazzjonijiet ta' Distribuzzjoni f'Faż Unika: Il-Ħelu għal Skidetta u Efffettivament tal-Infrastruttura ta' Ħarġ tal-Elettromobili
Single-Phase Distribution Transformers: The Key to Flexible and Efficient Deployment of EV Charging Infrastructure
Flieħet tal-infrastruttura ta’ ċarġa tal-vaħħal elettriku, l-ġilb tas-soluzzjonijiet ta’ fornitura ta’ potenza tri-faċi tradizzjonali solit stabbilixxu sfide kif l-ċikli tal-installazzjoni tajjin u modifiki estensivi, speċjalment f’skenariji distributivi mhux imbilanżati. Il-transformatori ta’ distribuzzjoni single-phase qed jiġu konsidrati bħala soġġoż importanti ma’ avantaggi uniki.
Application Pain Points: Value Anchors of Single-Phase Transformers
- Low-Voltage Grid Capacity Bottlenecks
- Il-transformatori residenzjali/kommerċjali jiġu saturati skont u jissopportaw tikka 2–3 postijiet ta’ ċarġa veloċi qabel ma jiġu rraggiunti l-limiti.
- L-upgrades tal-kapaċità jiżvilupaw fl-6–12 xahar, ma jkunux kapabili li jisoddisfaw id-demanġ għal ċarġa li qiegħed tieħel.
- Distributed Power Supply Challenges
- L-postijiet ta’ komunità taċ-ċadis jew parking mill-mall disperżi huwa aktar minn 500m minn sors tas-silġ.
- Iċ-ċost ta’ tiftix tal-kabli tri-faċi huwa ¥800–1,200/m, li mhux ekonomika viabili.
- Legacy Urban Grid Constraints
- ID-distretti storici għandhom wirjiet komplikati infeħles minn 50mm².
- Iċ-ċhanges tri-faċi fiexu rikiedu scavi (approvazzjonijiet >3-xahar).
- North America/Japan-South Korea Demands
- Id-dominanza ta’ 120V/240V single-phase tgħaqqad il-kompattibilità.
- Il-15–25kW DC fast chargers ikunu aktar minn 60% ta’ share tal-mercant (data 2023 North American Charging Alliance).
