Isikhululo sokuTjaja i-AC VS DC

Ukuba ukhe wazibuza ukuba kutheni ibizwa ngokuba "yi-DC yokutshaja ngokukhawuleza," impendulo ilula. I-“DC” ibhekisa “kumbane othe ngqo,” uhlobo lwamandla olusetyenziswa ziibhetri. Izitishi zokutshaja zeNqanaba lesi-2 zisebenzisa i-“AC,” okanye “alternating current,” oya kuyifumana kwiindawo zezindlu eziqhelekileyo. Ii-EV zineetshaja ezingaphakathi emotweni eziguqula amandla e-AC abe yi-DC kwibhetri. Iitshaja ezikhawulezayo ze-DC ziguqula amandla e-AC ukuya kwi-DC ngaphakathi kwesikhululo sokutshaja kwaye zihambise amandla e-DC ngqo kwibhetri, yiyo loo nto zihlawulisa ngokukhawuleza.

Izitishi zethu zeChargePoint Express kunye ne-Express Plus zibonelela nge-DC ngokukhawuleza. Khangela imaphu yethu yokutshaja ukufumana indawo yokutshaja ngokukhawuleza kufutshane nawe.

Ukutshaja ngokukhawuleza kwe-DC kucacisiwe

Ukutshaja nge-AC lolona hlobo lulula lokutshaja ukulufumana - iivenkile zikho kuyo yonke indawo kwaye phantse zonke iitshaja ze-EV odibana nazo ezindlini, kwiiplaza zokuthenga, nakwiindawo zokusebenza ziiTshaja zeLevel2. Itshaja ye-AC inika amandla kwitshaja esebhodini yesithuthi, iguqula la mandla e-AC abe yi-DC ukuze kungene ibhetri. Izinga lokwamkelwa kwetshaja ekwibhodi liyahluka ngokohlobo kodwa lilinganiselwe ngenxa yeendleko, indawo kunye nobunzima. Oku kuthetha ukuba ngokuxhomekeke kwisithuthi sakho kunokuthatha naphi na ukusuka kwiiyure ezine okanye ezintlanu ukuya ngaphezulu kweeyure ezilishumi elinesibini ukuhlawula ngokupheleleyo kwiNqanaba lesi-2.

Ukutshaja ngokukhawuleza kwe-DC kudlula yonke imida yetshaja ekwibhodi kunye nokuguqulwa okufunekayo, endaweni yoko ukubonelela ngamandla eDC ngokuthe ngqo kwibhetri, isantya sokutshaja sinakho ukwanda kakhulu. Amaxesha okutshaja axhomekeke kubungakanani bebhetri kunye nesiphumo se-dispenser, kunye nezinye izinto, kodwa iimoto ezininzi ziyakwazi ukufumana intlawulo ye-80% malunga okanye ngaphantsi kweyure zisebenzisa uninzi lweetshaja ezikhawulezayo zeDC ezikhoyo ngoku.

Ukutshaja ngokukhawuleza kweDC kubalulekile kumgama omde/ukuqhuba umgama omde kunye neenqwelo ezinkulu. Ukutshintsha ngokukhawuleza kwenza abaqhubi bakwazi ukutshaja kwakhona ngexesha lemini yabo okanye kwikhefu elincinci ngokuchasene nokuqhagamshelwa ngobusuku, okanye iiyure ezininzi, ngentlawulo epheleleyo.

Izithuthi ezindala zinemiqathango evumela ukuba zibize kuphela ama-50kW kwiiyunithi ze-DC (ukuba bezikwazi kwaphela) kodwa ngoku kuphuma izithuthi ezitsha ezinokwamkela ukuya kutsho kuma-270kW. Ngenxa yokuba ubungakanani bebhetri bonyuke kakhulu ukusukela oko ii-EVs zokuqala zifike kwimarike, iitshaja zeDC bezifumana iziphumo eziphezulu eziya kuhambelana - ezinye ngoku zikwazi ukuya kuthi ga kwi-350kW.

Okwangoku, eMntla Melika kukho iintlobo ezintathu zokutshaja ngokukhawuleza kwe-DC: i-CHAdeMO, iNkqubo yokuTshaja eDityanisiweyo (CCS) kunye neTesla Supercharger.

Bonke abavelisi abakhulu betshaja ye-DC banikezela ngeeyunithi ezisemgangathweni ezininzi ezinikezela ukukwazi ukuhlawula ngeCCS okanye i-CHAdeMO kwiyunithi efanayo. I-Tesla Supercharger inokusebenzisa kuphela izithuthi zeTesla, nangona kunjalo izithuthi zeTesla ziyakwazi ukusebenzisa ezinye iitshaja, ngokukodwa i-CHAdeMO ye-DC yokutshaja ngokukhawuleza, nge-adapter.

 4.Isikhululo sokutshaja se-DC

Isikhululo sokutshaja se-DC sintsonkothe ​​kakhulu ngokwethekhnoloji kwaye amaxesha amaninzi zibiza kakhulu kunesikhululo sokutshaja i-AC kwaye ngaphezu koko sifuna umthombo onamandla. Ukongeza, isikhululo sokutshaja se-DC kufuneka sikwazi ukunxibelelana nemoto endaweni yeshaja esebhodini ukuze sikwazi ukuhlengahlengisa iiparitha zamandla aphumayo ngokwemeko kunye nokukwazi kwebhetri.

Ikakhulu ngenxa yexabiso kunye nobunzima bobuchwepheshe, sinokubala izikhululo ze-DC ezimbalwa kakhulu kunezikhululo ze-AC. Okwangoku kukho amakhulu kwaye abekwe kwimithambo ephambili.

Amandla omgangatho wesikhululo sokutshaja se-DC ngama-50kW, okt ngaphezu kokuphindwe kabini kunesikhululo se-AC. Izikhululo zokutshaja ezikhawulezayo zinamandla ukuya kuthi ga kwi-150 kW, kwaye iTesla iye yaphuhlisa izitishi zokutshaja ezikhawulezayo ze-ultra-mega-fast ezinemveliso ye-250 kW.

Nangona kunjalo, ukutshaja okucothayo kusetyenziswa izitishi ze-AC kuthambile kwiibhetri kwaye kuyanceda ubomi bazo obude, ngoko ke elona qhinga lifanelekileyo kukuhlawulisa ngesikhululo se-AC kwaye usebenzise izikhululo ze-DC kuhambo olude kuphela.

Isishwankathelo

Ngenxa yokuba sineentlobo ezimbini zangoku (AC kunye ne-DC), kukho izicwangciso ezimbini xa utshaja imoto yombane.

Kuyenzeka ukuba usebenzise isikhululo sokutshaja se-AC apho itshaja ikhathalela ukuguqulwa. Olu khetho lucotha, kodwa luyabiza kwaye luthambile. Iitshaja ze-AC zikhupha ukuya kuthi ga kwi-22 kW kwaye ixesha elifunekayo lokutshaja ngokupheleleyo lixhomekeke kuphela kwimveliso yetshaja ekwibhodi.

Kwakhona kunokwenzeka ukusebenzisa izikhululo ze-DC, apho ukutshaja kubiza kakhulu, kodwa kuya kwenzeka kwimizuzu embalwa. Ngokuqhelekileyo, imveliso yabo yi-50 kW, kodwa kulindeleke ukuba inyuke kwixesha elizayo. Amandla eetshaja ezikhawulezayo yi-150 kW. Zombini zibekwe kufutshane neendlela eziphambili kwaye kufuneka zisetyenziselwe uhambo olude kuphela.

Ukwenza imeko ibe nzima ngakumbi, kukho iintlobo ezahlukeneyo zokuxhuma izixhumi zokutshaja, umboniso esiwubonisayo. Nangona kunjalo, imeko iyaguquka kwaye imigangatho yamazwe ngamazwe kunye nee-adapters zivela, ngoko kwixesha elizayo, akuyi kuba yingxaki enkulu kuneentlobo ezahlukeneyo zeesokethi kwihlabathi.
