Njengoba imakethe yezimoto zikagesi yomhlaba wonke ikhula ngokushesha, ukuthuthukiswa kwengqalasizinda yokushaja sekuyinto ebalulekile ekushayeleni. Phakathi kwalezi, iziteshi zokushaja ze-DC, njengendlela yokushaja ethuthuke kakhulu futhi elula, kancane kancane ziba yingqikithi yenethiwekhi yokushaja izimoto zikagesi.
Isiteshi sokushaja se-DC, njengoba igama lisho, yidivayisi eshaja amabhethri ezimoto kagesi isebenzisa i-direct current. Uma kuqhathaniswa neziteshi zokushaja ze-AC zendabuko, iziteshi zokushaja ze-DC zinezinzuzo ezibalulekile zesivinini sokushaja esisheshayo kanye nokusebenza kahle okuphezulu. Zingaguqula ngqo amandla e-AC kusuka kugridi abe amandla e-DC, zishaje ibhethri lemoto ngqo, ngaleyo ndlela zinciphise kakhulu isikhathi sokushaja. Isibonelo, isiteshi sokushaja se-DC esingu-150kW singashaja imoto kagesi ibe ngu-80% ngemizuzu engama-30, kanti isiteshi sokushaja se-AC singathatha amahora amaningana ngaphansi kwezimo ezifanayo.
Ngokuphathelene nobuchwepheshe, ukwakheka nokukhiqizwa kweziteshi zokushaja ze-DC kuhilela ubuchwepheshe obuningi obubalulekile. Okokuqala, kukhona ubuchwepheshe bokuguqulwa kwamandla, obusebenzisa abaguquli abaphumelelayo ukuguqula amandla e-AC abe amandla e-DC azinzile. Okwesibili, kukhona uhlelo lokupholisa; ngenxa yamandla aphezulu ahilelekile ekushajeni okusheshayo, uhlelo lokupholisa olusebenzayo lubalulekile ekuqinisekiseni ukusebenza okuphephile nokuzinzile kwemishini. Ngaphezu kwalokho, iziteshi zokushaja ze-DC zanamuhla zihlanganisa izinhlelo zokulawula ezihlakaniphile ezingaqapha amapharamitha ahlukahlukene ngesikhathi sangempela ngesikhathi senqubo yokushaja, njenge-voltage, i-current, kanye nezinga lokushisa, ukuqinisekisa ukushaja okusebenzayo nokuphephile.
Ukwanda kweziteshi zokushaja ze-DC kubalulekile hhayi nje kuphela kubasebenzisi bezimoto zikagesi kodwa futhi nasekuthuthukisweni okuluhlaza komphakathi wonke. Okokuqala, ikhono lokushaja okusheshayo lithuthukisa ukusebenziseka kalula kwezimoto zikagesi, kuqede "ukukhathazeka kobubanzi" babasebenzisi, ngaleyo ndlela kukhuthaze ukwamukelwa kwezimoto zikagesi. Okwesibili, iziteshi zokushaja ze-DC zingahlanganiswa nezinhlelo zokukhiqizwa kwamandla avuselelekayo (njengamandla elanga nawomoya). Ngamagridi ahlakaniphile, enza kube lula ukusetshenziswa kukagesi oluhlaza, kunciphise ukuthembela kumafutha endabuko, kanye nokunciphisa ukukhishwa kwekhabhoni.
Njengamanje, amazwe amaningi nezifunda emhlabeni wonke zikhuthaza ngenkuthalo ukwakhiwa kweziteshi zokushaja ze-DC. Isibonelo, iShayina, njengemakethe yezimoto zikagesi enkulu kunazo zonke emhlabeni, isakaze kakhulu iziteshi zokushaja ze-DC emadolobheni amakhulu nasezindaweni zesevisi yemigwaqo emikhulu. Amazwe amaningana aseYurophu nawo asungula ngenkuthalo amanethiwekhi okushaja ngesivinini esikhulu, ehlela ukufeza ukumbozwa okuphelele eminyakeni ezayo. E-United States, ukubambisana phakathi kukahulumeni namabhizinisi azimele kusheshisa ukwakhiwa kweziteshi zokushaja ze-DC ezweni lonke.
Uma sibheka esikhathini esizayo, amathuba okuthuthukiswa kweziteshi zokushaja ze-DC athembisa kakhulu. Ngokuthuthuka okuqhubekayo kwezobuchwepheshe, isivinini sokushaja sizokhula kakhulu, futhi izindleko zemishini zizoncipha kancane kancane. Ngaphezu kwalokho, ukuthambekela kobuhlakani kanye nokuxhumana kweziteshi zokushaja kuzozenza zikwazi ukudlala indima enkulu emadolobheni ahlakaniphile kanye nezokuthutha ezihlakaniphile.
Ekuphetheni, njengezindawo ezihamba phambili kwezobuchwepheshe bokushaja izimoto zikagesi, iziteshi zokushaja ze-DC ziguqula amaphethini ethu okusebenzisa ukuhamba namandla. Zihlinzeka ngolwazi lokushaja olulula kubasebenzisi bezimoto zikagesi futhi zinegalelo ekuthuthukisweni okuluhlaza emhlabeni jikelele. Esikhathini esizayo, sinesizathu esizwakalayo sokulindela ukuthi ngokwamukelwa kabanzi kweziteshi zokushaja ze-DC kanye nokusungula izinto ezintsha zobuchwepheshe okuqhubekayo, izimoto zikagesi zizoletha ngempela inkathi entsha yentuthuko esheshayo.
