Beihai Powder, moetapele oa litharollo tse ncha tsa ho tjhaja tsa EV, e motlotlo ho hlahisa "Tjhajara e nyane ea DC ea 20kw-40kw“–tharollo e fetolang papali e etselitsoeng ho koala sekheo pakeng tsa ho tjhaja butle ha AC leho tjhaja ka potlako ha DC e matla haholo. E entsoe ka lebaka la ho tenyetseha, theko e tlase, le lebelo, tjhaja ena e matlafatsa dikgwebo le ditjhaba ho amohela ho tsamaya ho tsitsitseng ntle le ho beha bokgoni kotsing.
Litjhajara tse nyane tsa DC(20kW-40kW) e fana ka melemo e meholo ho feta matla a tloaelehileng a matla a phahamengLitjhaja tsa DC(120kW+). Li theko e tlase ebile li fokotsa litšenyehelo tsa ho kenya ka lebaka la ntlafatso e fokolang ea gridi. Tšebeliso ea tsona ea matla e itekanetseng e fokotsa litšenyehelo tsa ts'ebetso, e fana ka ROI e potlakileng (likhoeli tse 6-18). Litjhaja tse nang le matla a phahameng li bitsa chelete e ngata 'me li hloka meralo ea motheo e pharaletseng 'me li na le linako tse telele tsa ROI (lilemo tse 2-5).
Litjhaja tse nyane tsa DC li tenyetseha haholo, li sebetsa ho lipotoloho tse tloaelehileng tsa 220V-380V le libaka tse nyane tse lekanang (0.5-1).㎡). Li sebetsa ka matsatsi a 1-3, li loketse mabenkele a maholo, liofisi le lihotele. Litjhaja tse matla li hloka lipotoloho tse nang le motlakase o phahameng 'me li nka likhoeli tse 1-3 ho li kenya, li li fokotsa litseleng tse kholo le liteisheneng tse khethehileng.
Ka lebelo la ho tjhaja la 20-50kW (100-250 km/h), ditjhaja tse nyane tsa DC di loketse di-EV tse nyane ho isa ho tse mahareng (≤80kWh) mme o sebelise ditsamaiso tse bonolo tsa ho phodisa, ho netefatsa botshepehi le bophelo ba dilemo tse 8-10.Seteishene sa ho tjhaja sa DC(120-350kW, 500-1000 km/h) e sebetsana le di-EV tse kgolo (≥100kWh) empa e itshetlehile ka ho phodisa metsi ho rarahaneng, ho eketsa sekgahla sa ho hloleha le ho fokotsa nako ya bophelo ho fihlela dilemong tse 5-8.
Litjhajara tse nyane tsa DC li ipabola libakeng tsa khoebo le tsa sechaba, li fana ka ho tjhaja ka theko e tlase bakeng sa likepe (mohlala, litekesi, thepa) le libaka tse hole tse nang le bokhoni bo fokolang ba gridi. Li fana ka boiphihlelo bo bonolo ba ho li sebelisa ka linako tsa ho tjhaja tsa lihora tse 1-3, litefiso tse tlase, le ts'epo e phahameng. Litjhajara tse matla a phahameng, leha li potlakile, li betere bakeng sa ho eketsa maemo a tšohanyetso empa li tla le litšenyehelo tse phahameng.
Ka tikoloho, litjhajara tse nyane tsa DC li tsamaisana le maano a eneji ea litoropo, li na le tšilafalo e tlase ea harmonic, 'me li hokahana le litsamaiso tsa letsatsi/poloko. Litjhajara tse nang le matla a phahameng hangata li hloka mangolo a tumello ea indasteri 'me li ka hatella li-grid tsa lehae.
Ka bokhutšoanyane, litjhajara tse nyane tsa DC li theko e tlase, li tenyetseha ebile lia tšoarella, e leng se etsang hore li be ntle bakeng sa tšebeliso ea litoropo le ea khoebo, ha li le matla a holimo.litjhaja tsa koloi ea motlakasee ntse e le ea bohlokoa bakeng sa maemo a sephethephethe se phahameng le a hole.
