iimveliso

I-backup yebhetri yenzelwe ukugcina i-xPM egcwele ngokupheleleyo ubuncinane bemizuzu engama-20. Iya kucinywa xa i-voltage ifikelela kwi-38 volts ukuthintela ukunikezelwa kombane ekuphumeni kulawulo kwaye i-alamu iya kuveliswa. Iibhetri ezinokutshajwa kwakhona ziya kuphulukana namandla azo okutshaja ngokupheleleyo ekuhambeni kwexesha kwaye kuya kufuneka ukuba zivavanywe kwaye zitshintshwe xa ziwela ngaphantsi kweepesenti ezingama-60 zomthamo wazo wokuqala. Ugcino lwebhetri luyilelwe ukuba lusebenze kwinkonzo yokulinda (float) malunga neminyaka emihlanu. Iminyaka emihlanu isekelwe kwibhetri egcinwe kwi-20C (68F) kwaye i-voltage yentlawulo ye-float igcinwe phakathi kwe-2.25 kunye ne-2.30 volts ngeseli. Oku kuquka ukukhutshwa kwebhetri ngokupheleleyo kanye kwiinyanga ezintathu. Akukho bhetri kufuneka ishiywe isebenza kwiminyaka emihlanu, kwaye ukuba akukho lungiso lwenziwayo kufuneka itshintshwe rhoqo emva kweminyaka emithathu. Ubomi benkonzo buchatshazelwa ngokuthe ngqo kwinani lokukhutshwa, ubunzulu bokukhutshwa, ukushisa kwe-ambient, kunye ne-voltage yokutshaja. Ubomi benkonzo obulindelekileyo bunokufinyezwa nge-20% kwi-10C nganye apho i-ambient ingaphezu kwe-20C. Iibhetri akufuneki zishiywe kwimeko yokukhutshwa. Oku kuvumela ukuba i-sulfating yenzeke eya kwandisa ukuchasana kwangaphakathi kwebhetri kunye nokunciphisa umthamo wayo. Izinga lokuzikhupha limalunga ne-3% ngenyanga kwi-ambient ye-20C. Izinga lokuzikhupha ngokwakho liphinda-phinda kwi-10C nganye kwindawo ejikeleze i-20C. Umbane okhutshiweyo webhetri akufuneki uhambe ngaphantsi kwe-1.30 volts ukugcina obona bomi bebhetri bugqwesileyo. Ngaloo nto engqondweni kucetyiswa ukuba ngamaxesha athile kulayishwe uvavanyo lweebhetri ukuqinisekisa ukuba banesakhono esaneleyo sokugcina inkqubo ngexesha lokuphela kombane. Uvavanyo kufuneka lwenziwe rhoqo ngonyaka kwaye rhoqo njengoko bekhula kwaye beqala ukuphulukana namandla abo. Uvavanyo lomthwalo luyacetyiswa ukuba lungasebenzi xa kunokwenzeka njengoko akuyi kubakho i-backup yebhetri ekhoyo ngelixa usenza uvavanyo kunye nokutshaja ipakethi yebhetri kungathatha ukuya kwiiyure ze-16. Ukuba nesithuba esikhoyo sokutshintshana, ngakumbi xa usenza inkqubo, lukhetho lobulumko olukhokelela kwixesha elincinane ngaphandle kokugcinwa kwebhetri kwaye uvumele ibhetri evavanyiweyo ukuba itshajwe kwakhona kwibhentshi engaphandle kwenkqubo ukuze kutshintshelwe kwixa elizayo ngovavanyo olulandelayo. Ukuba ulondolozo lwarhoqo alwenziwanga isindululo kukutshintsha ubuncinane qho emva kweminyaka emithathu kunemihlanu.
