AC VS DC Charging Station

Ngati munayamba mwadzifunsapo chifukwa chake imatchedwa "DC kuthamangitsa mwachangu," yankho ndi losavuta."DC" amatanthauza "kulunjika," mtundu wa mphamvu zomwe mabatire amagwiritsa ntchito.Malo ochajila a Level 2 amagwiritsa ntchito “AC,” kapena “alternating current,” yomwe mumapeza m’malo ogulitsira pakhomo.Ma EV ali ndi ma charger okwera mkati mwagalimoto omwe amasintha mphamvu ya AC kukhala DC ya batri.Ma charger othamanga a DC amasintha mphamvu ya AC kukhala DC mkati mwa malo ochapira ndikupereka mphamvu ya DC molunjika ku batri, chifukwa chake amalipira mwachangu.

Mawayilesi athu a ChargePoint Express ndi Express Plus amapereka DC kulipiritsa mwachangu.Sakani mapu athu olipira kuti mupeze malo ochapira mwachangu pafupi ndi inu.

Kufotokozera Kwachangu kwa DC Kufotokozera

Kulipiritsa kwa AC ndiye njira yosavuta kwambiri yopezera - malo ogulitsira ali paliponse ndipo pafupifupi ma charger onse a EV omwe mumakumana nawo kunyumba, malo ogulitsira, ndi malo antchito ndi Level2 Charger.Chaja ya AC imapereka mphamvu ku charger yomwe ili m'galimoto, kutembenuza mphamvu ya AC kukhala DC kuti ilowe mu batire.Mlingo wovomerezeka wa charger yomwe ili m'bwalo imasiyanasiyana malinga ndi mtundu wake koma ndizochepa pazifukwa zamtengo, malo ndi kulemera kwake.Izi zikutanthauza kuti kutengera galimoto yanu imatha kutenga kulikonse kuyambira maola anayi kapena asanu mpaka kupitilira maola khumi ndi awiri kuti ifike pa Level 2.

DC Fast Charging imadutsa malire onse a chojambulira pa bolodi ndikusintha kofunikira, m'malo mwake kupereka mphamvu ya DC molunjika ku batri, kuthamanga kwacharging kumatha kuchulukirachulukira.Nthawi zolipiritsa zimatengera kukula kwa batri ndi kutulutsa kwa chotulutsa, ndi zina, koma magalimoto ambiri amatha kupeza 80% mkati mwa ola limodzi kapena ola limodzi pogwiritsa ntchito ma charger othamanga a DC omwe alipo.

Kuthamangitsa mwachangu kwa DC ndikofunikira pakuyendetsa mtunda wautali / mtunda wautali komanso zombo zazikulu.Kutembenuka mwachangu kumathandizira madalaivala kuti aziwonjezera masana awo kapena panthawi yopuma pang'ono kusiyana ndi kulumikizidwa usiku wonse, kapena kwa maola ambiri, kuti alipirire.

Magalimoto akale anali ndi malire omwe amangowalola kuti azilipiritsa pa 50kW pamayunitsi a DC (ngati adatha nkomwe) koma magalimoto atsopano tsopano akutuluka omwe amatha kuvomereza mpaka 270kW.Chifukwa kukula kwa batire kwachulukirachulukira kuyambira pomwe ma EV oyamba adagundika pamsika, ma charger a DC akhala akupeza zotulutsa zambiri kuti zigwirizane - pomwe ena akutha mpaka 350kW.

Pakali pano, ku North America pali mitundu itatu ya DC yothamanga mofulumira: CHAdeMO, Combined Charging System (CCS) ndi Tesla Supercharger.

Onse opanga ma charger a DC amapereka mayunitsi osiyanasiyana omwe amapereka mwayi wolipiritsa kudzera pa CCS kapena CHAdeMO kuchokera pagawo lomwelo.Tesla Supercharger imatha kugwiritsa ntchito magalimoto a Tesla okha, komabe magalimoto a Tesla amatha kugwiritsa ntchito ma charger ena, makamaka CHAdeMO ya DC kulipira mwachangu, kudzera pa adapter.

Malo ochapira a DC ndizovuta kwambiri mwaukadaulo ndipo nthawi zambiri ndi okwera mtengo kuposa poyatsira AC komanso pamafunika gwero lamphamvu.Kuphatikiza apo, malo opangira magetsi a DC amayenera kulumikizana ndi galimoto m'malo mwa chojambulira pa bolodi kuti athe kusintha magawo amagetsi molingana ndi momwe batire ilili komanso kuthekera kwake.

Makamaka chifukwa chamitengo komanso zovuta zaukadaulo, titha kuwerengera masiteshoni ochepera a DC kuposa masiteshoni a AC.Pakali pano pali mazana a iwo ndipo ali pa mitsempha yaikulu.

Mphamvu yokhazikika ya siteshoni ya DC ndi 50kW, mwachitsanzo, kuwirikiza kawiri mphamvu ya siteshoni ya AC.Masiteshoni othamangitsa kwambiri ali ndi mphamvu zofikira 150 kW, ndipo Tesla yapanga masiteshoni othamangitsa kwambiri omwe ali ndi mphamvu ya 250 kW.

Komabe, kulipiritsa pang'onopang'ono pogwiritsa ntchito masiteshoni a AC ndikosavuta kwa mabatire ndipo kumathandizira moyo wawo wautali, kotero njira yabwino ndikulipiritsa kudzera pa AC station ndikugwiritsa ntchito masiteshoni a DC pamaulendo ataliatali.

Chidule

Chifukwa chakuti tili ndi mitundu iwiri yamakono (AC ndi DC), palinso njira ziwiri poyendetsa galimoto yamagetsi.

Ndi zotheka kugwiritsa ntchito malo opangira AC pomwe chojambulira chimasamalira kutembenuka.Njira iyi ndi yocheperako, koma yotsika mtengo komanso yofatsa.Ma charger a AC amakhala ndi mphamvu yofikira ku 22 kW ndipo nthawi yofunikira kuti ikhale yokwanira ndiye zimangotengera kutulutsa kwa charger yomwe ili pa board.

Ndikothekanso kugwiritsa ntchito masiteshoni a DC, komwe kulipiritsa kumakhala kokwera mtengo, koma kudzachitika mkati mwa mphindi zochepa.Kawirikawiri, zotsatira zake ndi 50 kW, koma zikuyembekezeka kuwonjezeka m'tsogolomu.Mphamvu ya ma charger othamanga ndi 150 kW.Onsewa ali mozungulira misewu ikuluikulu ndipo ayenera kugwiritsidwa ntchito maulendo ataliatali okha.

Kuti zinthu zikhale zovuta kwambiri, pali mitundu yosiyanasiyana ya zolumikizira zolipiritsa, mwachidule zomwe timapereka.Komabe, zinthu zikuyenda bwino ndipo miyezo yapadziko lonse lapansi ndi ma adapter akubwera, kotero m'tsogolomu, sipadzakhala vuto lalikulu kuposa mitundu yosiyanasiyana yazitsulo padziko lapansi.
