Njengoko imakethi yezithuthi zombane yehlabathi isanda ngokukhawuleza, uphuhliso lweziseko ezingundoqo zokutshaja luye lwaba yeyona nto ibalulekileyo yokuqhuba. Phakathi kwezi, izikhululo zokutshaja ze-DC, njengeyona ndlela iphambili nefanelekileyo yokutshaja, ngokuthe ngcembe iba ngundoqo wothungelwano lokutshaja isithuthi sombane.
Isikhululo sokutshaja se-DC, njengoko igama libonisa, sisixhobo esibiza iibhetri zesithuthi sombane sisebenzisa umsinga othe ngqo. Xa kuthelekiswa nezikhululo zokutshaja ze-AC eziqhelekileyo, izikhululo zokutshaja ze-DC zineengenelo ezibalulekileyo zesantya sokutshaja ngokukhawuleza kunye nokusebenza okuphezulu. Banokuguqula ngokuthe ngqo amandla e-AC ukusuka kwigridi ukuya kumandla eDC, ukutshaja ibhetri yesithuthi ngokuthe ngqo, ngaloo ndlela behlisa kakhulu ixesha lokutshaja. Umzekelo, isikhululo sokutshaja i-150kW DC sinokubiza isithuthi sombane ukuya kuma-80% kwimizuzu engama-30, ngelixa isikhululo sokutshaja i-AC sinokuthatha iiyure ezininzi phantsi kweemeko ezifanayo.
Ngokwethekhinoloji, uyilo kunye nokuveliswa kwezikhululo zokutshaja ze-DC kubandakanya ubuninzi betekhnoloji eziphambili. Okokuqala, kukho itekhnoloji yokuguqula amandla, esebenzisa abaguquli abasebenzayo ukuguqula amandla e-AC abe ngamandla azinzileyo eDC. Okwesibini, kukho inkqubo yokupholisa; ngenxa yamandla aphezulu abandakanyekayo ekutshajisweni okukhawulezayo, inkqubo yokupholisa esebenzayo ibalulekile ekuqinisekiseni ukusebenza ngokukhuselekileyo nokuzinzileyo kwezixhobo. Ukongeza, izikhululo zokutshaja ze-DC zanamhlanje zidibanisa iinkqubo zokulawula ezinengqondo ezinokubeka iliso kwiiparamitha ezahlukeneyo ngexesha lokwenyani ngexesha lenkqubo yokutshaja, njengombane, okwangoku, kunye nobushushu, ukuqinisekisa ukutshaja okusebenzayo nokukhuselekileyo.
Ukwanda kwezikhululo zokutshaja ze-DC kubalulekile kungekuphela nje kubasebenzisi bezithuthi zombane kodwa nakuphuhliso lohlaza loluntu luphela. Okokuqala, amandla okutshaja ngokukhawuleza aphucula ukusebenziseka lula kokusebenzisa izithuthi zombane, ukuphelisa "ixhala loluhlu" lwabasebenzisi, kwaye ngaloo ndlela kukhuthazwa ukwamkelwa kwezithuthi zombane. Okwesibini, izikhululo zokutshaja zeDC zinokudityaniswa neenkqubo zokuvelisa amandla ahlaziyekayo (afana namandla elanga kunye namandla omoya). Ngokusebenzisa iigridi ezihlakaniphile, zenza ukusetyenziswa ngokufanelekileyo kombane oluhlaza, ukunciphisa ukuthembela kumafutha emveli, kunye nokukhutshwa kwekhabhoni ephantsi.
Okwangoku, amazwe amaninzi kunye nemimandla yehlabathi jikelele ikhuthaza ukwakhiwa kwezikhululo zokutshaja ze-DC. Umzekelo, iChina, njengeyona ntengiso inkulu yezithuthi zombane kwihlabathi, isasaze kakhulu izikhululo zokutshaja zeDC kwizixeko ezikhulu nakwiindawo zenkonzo yendlela. Amazwe aliqela aseYurophu nawo aseka uthungelwano lokutshaja olunesantya esiphezulu, ecwangcisa ukufezekisa ukhuseleko olubanzi kwiminyaka ezayo. EUnited States, intsebenziswano phakathi kukarhulumente namashishini abucala ikhawulezisa ukwakhiwa kwezikhululo zokutshaja zeDC kwilizwe lonke.
Ukujonga kwikamva, amathuba ophuhliso lwezikhululo zokutshaja ze-DC athembisa kakhulu. Ngophuhliso oluqhubekayo lwetekhnoloji, isantya sokutshaja siya kunyuka ngakumbi, kwaye iindleko zezixhobo ziya kuhla kancinci. Ngaphaya koko, indlela eya kubukrelekrele kunye nothungelwano lwezikhululo zokutshaja ziya kubenza badlale indima enkulu kwizixeko ezikrelekrele kunye nothutho olukrelekrele.
Ukuqukumbela, njengophambili kwitekhnoloji yokutshaja isithuthi sombane, izikhululo zokutshaja ze-DC ziguqula iindlela zethu zokuhamba kunye nokusetyenziswa kwamandla. Banikezela ngamava afanelekileyo okuhlawula kubasebenzisi bezithuthi zombane kwaye bafake isandla kuphuhliso lohlaza lwehlabathi. Kwixesha elizayo, sinesizathu sokulindela ukuba ngokwamkelwa ngokubanzi kwezikhululo zokutshaja ze-DC kunye nokwenziwa ngokutsha kobuchwepheshe obuqhubekayo, izithuthi zombane ziya kuzisa ngokwenene ixesha elitsha lophuhliso olukhawulezayo.
