Ngamakhulu ezigidi zamaselula emhlabeni wonke, ukuzuza ukuphepha kudinga izinga lokwehluleka elingaphansi kwesigidi esisodwa kweziyikhulu. Kodwa-ke, izinga lokuhluleka kwamabhodi wesifunda ngokuvamile liphakeme kakhulu kunelilodwa kwezigidi eziyikhulu. Ngakho-ke, ukwakheka kwesistimu yebhethri kufanele kufake okungenani imigqa emibili yokuzivikela. Iphutha elivamile lokuklama ukushaja ngqo iphakethe lebhethri nge-adaptha. Lokhu kubeka wonke umthwalo wemfanelo wokuvikela ukukhokhiswa ngokweqile ebhodini lokuvikela ephaketheni lebhethri. Nakuba izinga lokuhluleka kwebhodi lokuvikela liphansi, ngisho nokukodwa esigidini, ukuqhuma kusenzeka nsuku zonke emhlabeni jikelele. Uma isistimu yebhethri ihlinzeka ngemigqa emibili yokuzivikela ngokumelene nokukhokhiswa ngokweqile,{6}}ukuphuma, kanye nokudlulela, ngokuzivikela ngakunye kunezinga lokuhluleka kokukodwa ezinkulungwaneni eziyishumi, imigqa emibili yokuzivikela inganciphisa izinga lokuhluleka libe linye ezigidini eziyikhulu.
Umsebenzi Wephakethe Lebhethri: Umkhawulo Wamanje. Uma sithatha isistimu yebhethri yomakhalekhukhwini njengesibonelo, isistimu yokuvikela ukushajwa ngokweqile isebenzisa amandla kagesi eshaja asethwe cishe ku-4.2V ukuze kuzuzwe isendlalelo sokuqala sokuvikela. Ngale ndlela, noma ngabe ibhodi lokuvikela ephaketheni lebhethri lihluleka, ibhethri ngeke lishajwe ngokweqile futhi libe yingozi. Isendlalelo sesibili sokuvikela umsebenzi wokuvikela ukukhokhiswa ngokweqile ebhodini lokuvikela, ngokuvamile elibekwe ku-4.3V. Lokhu kusho ukuthi ibhodi lokuvikela ngokuvamile alidingi ukunqamula umsinga wokushaja; isebenza kuphela lapho i-voltage yeshaja iphezulu ngokungavamile. Ukuvikelwa kwe-Overcurrent kuphathwa ibhodi lokuvikela kanye nomkhawulo wamanje, okunikeza izendlalelo ezimbili zokuvikela kumasekethe amafushane adlulele ngokweqile nangaphandle. Njengoba ukukhishwa ngaphezulu{8}}kuvela kuphela ngesikhathi sokusetshenziswa komkhiqizo we-elekthronikhi, ibhodi lesekhethi yomkhiqizo we-elekthronikhi ngokuvamile linikeza isendlalelo sokuqala sokuvikela, kuyilapho ibhodi lokuvikela kuphakethe lebhethri linikeza okwesibili. Uma umkhiqizo we-elekthronikhi uthola amandla kagesi angaphansi kuka-3.0V, kufanele uvale ngokuzenzakalelayo. Uma lo msebenzi ungafakiwe ekwakhiweni komkhiqizo, ibhodi lokuvikela lizovala isifunda sokukhipha lapho i-voltage yehla ibe ngu-2.4V.
