"Ukuhlaziywa" Kwexesha Elizayo Kokutshaja Kwe-EV

Ngenxa yokukhuthazwa kancinci kancinci kunye nophuhliso lwemizi-mveliso yezithuthi zombane kunye nophuhliso olukhulayo lwetekhnoloji yezithuthi zombane, iimfuno zobugcisa zezithuthi zombane zokutshaja iinqwaba ziye zabonisa umkhwa oqhubekayo, zifuna ukuba iinqwaba zokutshaja zisondele kangangoko kwiinjongo ezilandelayo:

(1) Ukutshaja ngokukhawuleza

Xa kuthelekiswa neebhetri zamandla ze-nickel-metal hydroxide kunye ne-lithium-ion ezinamathuba amahle ophuhliso, iibhetri zemveli ze-lead-acid zinezibonelelo zobuchwepheshe obuvuthiweyo, iindleko eziphantsi, umthamo omkhulu webhetri, iimpawu ezilungileyo zokukhupha ezilandela umthwalo kwaye azinasiphumo sememori, kodwa zikwanazo neenzuzo. Iingxaki zamandla aphantsi kunye nomgama omfutshane wokuqhuba ngetshaja enye. Ke ngoko, kwimeko apho ibhetri yamandla yangoku ingenakubonelela ngokuthe ngqo ngomgama ongaphezulu wokuqhuba, ukuba ukutshaja kwebhetri kunokufezekiswa ngokukhawuleza, ngandlela thile, kuya kuyisombulula isithende se-Achilles soluhlu olufutshane lokuqhuba lwezithuthi zombane.

(2) Ukutshaja Okuqhelekileyo

Phantsi kwemvelaphi yemarike yokubakho kweentlobo ezahlukeneyo zeebhetri kunye namanqanaba amaninzi e-voltage, izixhobo zokutshaja ezisetyenziswa kwiindawo zikawonke-wonke kufuneka zibe nakho ukuziqhelanisa neentlobo ezahlukeneyo zeenkqubo zebhetri kunye namanqanaba ahlukeneyo e-voltage, oko kukuthi, inkqubo yokutshaja kufuneka ibe nokuguquguquka kokutshaja kwaye I-algorithm yokulawula ukutshaja yeentlobo ezahlukeneyo zeebhetri inokufanisa iimpawu zokutshaja zeenkqubo ezahlukeneyo zebhetri kwizithuthi ezahlukeneyo zombane, kwaye inokutshaja iibhetri ezahlukeneyo. Ke ngoko, kwinqanaba lokuqala lokuthengiswa kwezithuthi zombane, kufuneka kwenziwe imigaqo-nkqubo kunye namanyathelo afanelekileyo ukuze kwenziwe umgangatho we-interface yokutshaja, iinkcukacha zokutshaja kunye nesivumelwano se-interface phakathi kwezixhobo zokutshaja ezisetyenziswa kwiindawo zikawonke-wonke kunye nezithuthi zombane.

(3) Ukutshaja okukrelekrele

Enye yezona zinto zibalulekileyo ezithintela uphuhliso kunye nokusasazwa kwezithuthi zombane kukusebenza kunye nenqanaba lokusetyenziswa kweebhetri zokugcina amandla. Injongo yokwenza ngcono indlela yokutshaja ibhetri ekrelekrele kukufezekisa ukutshaja ibhetri engonakalisiyo, ukujonga imeko yokukhutshwa kwebhetri, kunye nokuphepha ukukhupha ibhetri kakhulu, ukuze kufezekiswe injongo yokwandisa ubomi bebhetri kunye nokonga amandla. Uphuhliso lwetekhnoloji yesicelo sobukrelekrele bokutshaja lubonakala kakhulu kwezi zinto zilandelayo: itekhnoloji yokutshaja ekrelekrele, ephuculiweyo kunye neetshaja, izitishi zokutshaja; ukubala, isikhokelo kunye nolawulo olukrelekrele lwamandla ebhetri; itekhnoloji yokuxilonga ngokuzenzekelayo kunye nokugcinwa kokusilela kwebhetri.

(4) Ukuguqulwa kwamandla okusebenzayo

Izalathi zokusetyenziswa kwamandla ezithuthi zombane zinxulumene kakhulu neendleko zazo zokusebenza kwamandla. Ukunciphisa ukusetyenziswa kwamandla okusebenza kwezithuthi zombane kunye nokuphucula ukusebenza kakuhle kweendleko zezinye zezinto eziphambili ezikhuthaza uphuhliso lwemizi-mveliso yezithuthi zombane. Kwizikhululo zokutshaja, xa kujongwa ukusebenza kakuhle kokuguqulwa kwamandla kunye neendleko zokwakha, kufuneka kubekwe phambili izixhobo zokutshaja ezineenzuzo ezininzi ezifana nokusebenza kakuhle kokuguqulwa kwamandla kunye neendleko eziphantsi zokwakha.

(5) Ukudibanisa ukutshaja

Ngokuhambelana neemfuno ze-miniaturization kunye nokusebenza ngeendlela ezininzi kweenkqubo ezingaphantsi, kunye nokuphuculwa kokuthembeka kwebhetri kunye neemfuno zozinzo, inkqubo yokutshaja iya kudityaniswa nenkqubo yolawulo lwamandla ezithuthi zombane iyonke, idibanise ii-transistors zokudlulisa, ukufunyanwa kwangoku, kunye nokukhuselwa kokukhupha umva, njl. Umsebenzi, isisombululo sokutshaja esincinci nesidibeneyo sinokufezekiswa ngaphandle kwezixhobo zangaphandle, ngaloo ndlela songa indawo yoyilo lwezixhobo ezisele zezithuthi zombane, inciphisa kakhulu iindleko zenkqubo, kwaye iphucule isiphumo sokutshaja, kwaye yandise ubomi bebhetri.
