Na ke Lokela ho Sebelisa AC kapa DC ho Tjhaja Koloi ea Ka ea Motlakase?

Ha likoloi tsa motlakase (li-EV) li ntse li ata haholo, e 'ngoe ea lipotso tse atisang ho botsoa ke beng ba bacha ke:"Na ke lokela ho tjhaja koloi ya ka ka AC kapa DC?"Karabo e itshetlehile ka mekgwa ya hao ya ho kganna, meralo ya motheo ya ho tjhaja, le dintho tse lokelang ho elwa hloko mabapi le bophelo bo botle ba betri. Tataiso ena e tebileng e hlahloba dipharologanyo pakeng tsa ho tjhaja AC le DC, melemo le mathata a tsona, le hore na ke kgetho efe e molemo bakeng sa ditlhoko tsa hao.

Ho utloisisa ho tjhaja ha AC khahlanong le DC

1. Ho tjhaja ha AC ke eng?

• Kamoo e sebetsang kateng:
  • Liphetolelo tsa tjhaja ea hau ea EVMotlakase o Fetolanang (AC)ho tloha gridi ho ea hoMotlakase o Otlolohileng (DC)bakeng sa betri.
  • Ho tjhaja butle ho feta DC hobane phetoho e etsahala ka hare ho koloi.
• Dikgetho tse Tloaelehileng tsa ho tjhaja AC:
  • Boemo ba 1 (120V, 1.4–2.4 kW)– Lebenkele le tloaelehileng la ntlo, le eketsaLik'hilomithara tse 3–5 ka hora.
  • Boemo ba 2 (240V, 7–19.2 kW)– Litjhaja tsa lapeng kapa tsa sechaba, lia eketsoaLik'hilomithara tse 20–60 ka hora.

2. DC Fast Charging ke eng?

• Kamoo e sebetsang kateng:
  • E feta tjhaja e ka hare ho koloi, e e fepaMotlakase o Otlolohileng (DC)ka ho toba ka betring.
  • Ka potlako haholo hobane phetoho e etsahala kantle seteisheneng sa ho tjhaja.
• Likhetho tse Tloaelehileng tsa ho tjhaja DC:
  • Boemo ba 3 (400V–800V, 50–350 kW)– E eketsaLik'hilomithara tse 100–200 ka metsotso e 15–30.
  • E Potlakileng ka ho Fetisisa (800V+, 350+ kW)– Di-EV tse ncha (mohlala, Porsche Taycan, Hyundai Ioniq 5) di ka tjhaja10–80% ka metsotso e ka bang 18.

U Lokela ho Sebelisa DC Fast Charging Neng?

⚡E ntle ka ho fetisisa bakeng sa maeto a malelele

• Maetong a tsela, DC e tjhaja ka potlakoeketsa dimaele tse fetang 200 ka metsotso e ka bang 30.
• Bohlokoa bakeng sa li-EV tse nang lelibeteri tse nyane(mohlala, Nissan Leaf, Chevy Bolt).

⚡Litlatsetso tsa maemo a tšohanyetso

• Haeba tefiso ea hau e le tlase 'me u hloka ho eketsoa kapele.

⚠Empa ela hloko:

• Ho tjhaja DC khafetsa ho ka senya bophelo ba betri(liphuputso li bontša hore ~ ​​tahlehelo ea bokhoni e potlakileng ea 10–15%).
• Hase li-EV tsohle tse tšehetsang ho tjhaja ka potlako haholo– Hlahloba tekanyo e phahameng ka ho fetisisa ea kW ea koloi ea hau (mohlala, Tesla V3 Supercharger = 250 kW).

Bophelo ba Betri: Na ho tjhaja DC ho senya EV ea hau?

• Mocheso ke sera– Ho tjhaja ka potlako ha DC ho hlahisa mocheso o mongata, o ka:
  • Potlakisaho senyeha ha electrolyte.
  • Sesosaho penta ka lithium(ho fokotsa bokgoni ha nako e ntse e ya).
• Li-EV tsa sejoale-joale li fokotsa sena ka:
  • Mekhoa e sebetsang ea ho pholisa(libetri tse phodisitsweng ke metsi).
  • Sekhahla sa tefiso sea fokotseha(e lieha ka mor'a 80%).
