Isikhululo sokutshaja se-AC VS DC

Ukuba wakha wazibuza ukuba kutheni ibizwa ngokuba yi-“DC fast charging,” impendulo ilula. Igama elithi “DC” libhekisa “kumbane othe ngqo,” uhlobo lwamandla asetyenziswa ziibhetri. Izitishi zokutshaja zeNqanaba lesi-2 zisebenzisa “i-AC,” okanye “umbane otshintshanayo,” oza kuzifumana kwiindawo eziqhelekileyo zokuthengisa iimoto zasekhaya. Ii-EV zinetshaja ezingaphakathi emotweni eziguqula amandla e-AC abe yi-DC yebhetri. Iitshaja ezikhawulezayo ze-DC ziguqula amandla e-AC abe yi-DC ngaphakathi kwisitishi sokutshaja kwaye zihambisa amandla e-DC ngqo kwibhetri, yiyo loo nto zitshaja ngokukhawuleza.

Izikhululo zethu zeChargePoint Express kunye neExpress Plus zibonelela ngokutshaja ngokukhawuleza kweDC. Khangela imephu yethu yokutshaja ukuze ufumane indawo yokutshaja ngokukhawuleza kufutshane nawe.

Ichaziwe ngokuTshaja okuKhawulezayo kweDC

Ukutshaja kwe-AC lolona hlobo lulula lokutshaja olufumanekayo - iindawo zokuthengisa zikho kuyo yonke indawo kwaye phantse zonke iitshaja ze-EV odibana nazo emakhaya, kwiindawo zokuthenga, nakwiindawo zokusebenza ziitshaja zeLevel2. Itshaja ye-AC inika amandla kwitshaja ekwinqwelo, iguqula loo mandla e-AC abe yi-DC ukuze ingene ebhetrini. Izinga lokwamkelwa kwetshaja ekwinqwelo liyahluka ngokwegama kodwa lilinganiselwe ngenxa yeendleko, indawo kunye nobunzima. Oku kuthetha ukuba kuxhomekeke kwisithuthi sakho kunokuthatha naphi na ukusuka kwiiyure ezine okanye ezintlanu ukuya kwiiyure ezilishumi elinambini ukutshaja ngokupheleleyo kwiLevel 2.

Ukutshaja okuKhawulezayo kwe-DC kudlula yonke imida yetshaja ekwibhodi kunye nokuguqulwa okufunekayo, endaweni yoko kunika amandla e-DC ngqo kwibhetri, isantya sokutshaja sinokunyuswa kakhulu. Amaxesha okutshaja axhomekeke kubungakanani bebhetri kunye nemveliso ye-dispenser, kunye nezinye izinto, kodwa izithuthi ezininzi ziyakwazi ukufumana itshaja ye-80% malunga okanye ngaphantsi kweyure zisebenzisa iitshaja ze-DC ezikhawulezayo ezikhoyo ngoku.

Ukutshaja ngokukhawuleza kweDC kubalulekile xa uqhuba iimayile ezininzi/umgama omde kunye neenqwelo-mafutha ezinkulu. Ukukhawuleza kuvumela abaqhubi ukuba batshaje ngexesha lasemini okanye ngexesha lekhefu elincinci endaweni yokuba bafakwe kwi-intanethi ubusuku bonke, okanye iiyure ezininzi, ukuze batshaje ngokupheleleyo.

Iimoto ezindala zazinemida eyayizivumela ukuba zitshaje kwi-50kW kuphela kwiiyunithi zeDC (ukuba bezinako konke konke) kodwa ngoku kuvela iimoto ezintsha ezinokwamkela ukuya kuthi ga kwi-270kW. Ngenxa yokuba ubungakanani bebhetri bunyuke kakhulu ukusukela oko ii-EV zokuqala zafika kwimarike, iitshaja zeDC ziye zafumana amandla aphezulu ngokuthe ngcembe ukuze zihambelane - ezinye ngoku zinamandla okufika kwi-350kW.

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

Bonke abavelisi abakhulu beetshaja zeDC banikezela ngeeyunithi ezisemgangathweni ophezulu ezibonelela ngokukwazi ukutshaja ngeCCS okanye iCHAdeMO ukusuka kwiyunithi enye. I-Tesla Supercharger inokubonelela kuphela ngeenkonzo kwiimoto zeTesla, nangona kunjalo iimoto zeTesla ziyakwazi ukusebenzisa ezinye iitshaja, ngakumbi iCHAdeMO yokutshaja ngokukhawuleza kweDC, nge-adaptha.

 4.Isikhululo sokutshaja seDC

Isikhululo sokutshaja se-DC sintsonkothile kakhulu ngokwetekhnoloji kwaye sibiza kakhulu kunesikhululo sokutshaja se-AC kwaye ngaphezu koko sifuna umthombo onamandla. Ukongeza, isikhululo sokutshaja se-DC kufuneka sikwazi ukunxibelelana nemoto endaweni yetshaja esebhodini ukuze sikwazi ukulungisa iiparameter zamandla okukhupha ngokwemeko kunye namandla ebhetri.

Ngenxa yexabiso kunye nobunzima betekhnoloji, singabala izitishi zeDC ezimbalwa kakhulu kunezitishi ze-AC. Okwangoku kukho amakhulu azo kwaye zikwimithambo ephambili.

Amandla aqhelekileyo esikhululo sokutshaja se-DC yi-50kW, oko kukuthi, ngaphezulu kokuphindwe kabini kunalawo esikhululo se-AC. Izikhululo zokutshaja ezikhawulezayo kakhulu zinamandla afikelela kwi-150 kW, kwaye iTesla iphuhlise izikhululo zokutshaja ezikhawulezayo kakhulu ezinemveliso ye-250 kW.

Nangona kunjalo, ukutshaja kancinci usebenzisa izitishi ze-AC kuthambile kwiibhetri kwaye kunceda ukuhlala ixesha elide, ngoko ke icebo elifanelekileyo kukutshaja ngesitishi se-AC kwaye usebenzise izitishi ze-DC kuphela xa uhamba uhambo olude.

Isishwankathelo

Ngenxa yokuba sineentlobo ezimbini zamandla ombane (i-AC kunye ne-DC), kukwakho neendlela ezimbini zokutshaja imoto yombane.

Kunokwenzeka ukusebenzisa isikhululo sokutshaja se-AC apho itshaja ijongana notshintsho. Olu khetho lucothayo, kodwa lubiza kancinci kwaye luthambile. Iitshaja ze-AC zinamandla okukhupha amandla afikelela kwi-22 kW kwaye ixesha elifunekayo lokutshaja ngokupheleleyo lixhomekeke kuphela kumandla okukhupha itshaja ekwibhodi.

Kunokwenzeka nokusebenzisa izitishi zeDC, apho ukutshaja kubiza kakhulu, kodwa kuya kwenzeka kwimizuzu embalwa. Ngokwesiqhelo, imveliso yazo yi-50 kW, kodwa kulindeleke ukuba inyuke kwixesha elizayo. Amandla eetshaja ezikhawulezayo yi-150 kW. Zombini zikufutshane neendlela eziphambili kwaye kufuneka zisetyenziswe kuhambo olude kuphela.

Ukuze imeko ibe nzima ngakumbi, kukho iintlobo ezahlukeneyo zezihlanganisi zokutshaja, esizichaza ngokubanzi. Nangona kunjalo, imeko iyatshintsha kwaye imigangatho yamazwe ngamazwe kunye neeadaptha ziyavela, ngoko ke kwixesha elizayo, ayizukuba yingxaki enkulu kuneentlobo ezahlukeneyo zeesokhethi ehlabathini.
