Siilinso "plug in the wall" chabe; ikukhala node mu gridi yamagetsi yogawidwa, yokhoza kulinganiza katundu, kulamulira ma frequency, komanso kubwezera mphamvu ku gridi (V2G). Kumvetsetsa mfundo za ukadaulo uwu—kuyambira pamlingo wa semiconductor mpaka ma spreadsheet azachuma a Charge Point Operator (CPO)—ndikofunikira kwa aliyense wokhudzidwa ndi gawo lamakono la mphamvu ndi kuyenda.

Chaputala 2: Fiziki ya Kutumiza Mphamvu Mwachangu: Momwe DC Imagwirira Ntchito Pochaja Mwachangu

Kuti mumvetse bwino ubwino wa DC Fast Charging, choyamba munthu ayenera kumvetsetsa zofooka zazikulu za Alternating Current (AC). Gridi yamagetsi imapereka mabatire a AC, koma mabatire a lithiamu-ion—njira yosungira mphamvu yomwe imasankhidwa ndi ma EV amakono—amasunga mphamvu ngati Direct Current (DC). Munthawi yokhazikika ya Level 1 kapena Level 2 AC charging, "charger" kwenikweni ndi Intelligent EVSE (Electric Vehicle Supply Equipment) yomwe imagwira ntchito ngati chipata chotetezeka. Chaja yeniyeni—kusintha kwa AC kukhala DC—kumachitika mkati mwa galimoto kudzera pa On-Board Charger (OBC).

OBC ndi vuto lalikulu. Chifukwa iyenera kunyamulidwa mgalimoto, imayendetsedwa ndi kukula, kulemera, ndi mtengo wake. Ma EV ambiri amakono ali ndi ma OBC omwe ali ndi mphamvu kuyambira 7kW mpaka 11kW, ndipo mitundu ina yapamwamba imafika 22kW. Kuchaja batire ya 100kWh pa 11kW kumatenga pafupifupi maola 10. Izi ndizovomerezeka pakuchaja usiku wonse kunyumba koma ndizowopsa paulendo wautali.

DC Fast Charging imasuntha njira yosinthira galimoto kuchoka pa malo ochajira osasuntha. Pochita izi, zoletsa "zoyikika" zimachotsedwa. Chaja ya DC ikhoza kukhala yayikulu ngati firiji kapena chidebe chotumizira, zomwe zimathandiza kuti pakhale malo otenthetsera ambiri, mafani ozizira kwambiri, komanso zamagetsi zamagetsi zamagetsi zomwe zimagwira ntchito bwino kwambiri.

Kapangidwe ka mkati mwa chojambulira cha DC mwachangu kali ndi magawo angapo ofunikira:

1. Chiyanjano cha Gridi:Siteshoniyi imalumikizana ndi gridi ya AC yamagetsi apakati kapena otsika, nthawi zambiri imafuna transformer yapadera kuti igwire ntchito yofunikira kwambiri yamagetsi.
