Kungani amabhethri efa ngaphambi kwesikhathi?
Ngenxa yezizathu ezimbili - ukuphikisana kwabakhiqizi nokusetshenziswa okungalungile.
Amabhethri ezimoto ngokuvamile awalethwa - asebenza njalo iminyaka emihlanu, ngemva kwalokho ashintshwa amasha. Nokho, kukhona okuhlukile. Ngokuvamile, amabhethri "awafi" kusukela ekugugeni nhlobo, kodwa ngenxa yekhwalithi ephansi, izilonda eziningi emotweni, noma ukunganaki komnikazi wemoto.
Impilo yebhethri ngalinye inomkhawulo. Ikhiqiza ugesi ngenxa yokusabela okwenzeka ngaphakathi kudivayisi. Ukusabela kwamakhemikhali kanye ne-electrochemical kwenzeka ngokuqhubekayo ngisho nangemva kokuba ibhethri selakhiwe. Ngakho-ke, ukugcina amabhethri ukuze asetshenziswe esikhathini esizayo, uma sikubeka kancane, kuyisinqumo esinombono omfushane. Amabhethri ekhwalithi ephezulu asebenza ngokushelela amahora angama-5-7, ngemuva kwalokho ayeke ukubamba ukushaja futhi aphendule isiqalisi kabi. Yiqiniso, uma ibhethri ingaseyona eyangempela noma imoto isindala, konke kuhlukile.
Imfihlo yempilo yebhethri emfushane ngokujwayelekile ilula ngokweqile: imikhiqizo yezinhlobo ezaziwayo ezingena emakethe yesibili (okungukuthi, hhayi kumthwali wokuhambisa) zenziwa ngomgunyathi omkhulu, futhi izinkampani eziningi nezimboni zikhiqiza, noma kungokwasekuqaleni, kepha kuphezulu ngaphandle kuphela -quality factory amabhethri.
Ukuze kuncishiswe izindleko zokukhiqiza futhi ngesikhathi esifanayo intengo yokuthengisa yebhethri, abakhiqizi bebhethri banciphisa inani lamapuleti okuhola (amapuleti). Imikhiqizo enjalo, njengemisha, empeleni "ayikhi" futhi imoto iqala ngaphandle kwezinkinga ngisho nasebusika. Nokho, injabulo ayihlali isikhathi eside - ukunciphisa inani lamapuleti kuthinta kakhulu impilo yebhethri.
Ibhethri elinjalo lingahlolwa kuphela emithwalweni ezinyangeni ezimbalwa ngemuva kokuthengwa, ikakhulukazi ngomthwalo owandisiwe. Unganquma ukuthi usebenzisana nomkhiqizo wekhwalithi ephansi ngisho nasesigabeni sokukhetha nokuthenga. Umthetho ulula: lapho ibhethri lisinda, liba ngcono futhi lide. Ibhethri engasindi ayisebenzi.
Isizathu sesibili sokwehluleka okusheshayo kwamabhethri ukusetshenziswa okungalungile. Lapha, izimo ezahlukene sezingenzeka. Ukusebenza kwebhethri kuncike kakhulu kuzinga lokushisa le-ambient. Ebusika, amandla abo ehla kakhulu - babhekana nokukhishwa okujulile kakhulu lapho injini iqalwa, futhi ngesikhathi esifanayo ishajwa kabi yi-generator. Ukushaja okungaphansi okungamahlalakhona, kuhlanganiswe nokuphuma okujulile, kungacekela phansi ngisho nebhethri lekhwalithi ephezulu ngobusika obubodwa nje.
Amanye amadivaysi awakwazi ukwenziwa kabusha ngemva kokuhlanjululwa okukodwa kuphela kokuthi "zero" - isisindo esisebenzayo samapuleti avele agoqe. Lokhu kwenzeka, isibonelo, lapho umshayeli ezama ukuqala injini isikhathi eside emazingeni okushisa aphansi kakhulu noma lapho eshayela nge-generator ehlulekile.
Ehlobo, kuvame ukuba nenye inkathazo: ngenxa yokushisa ngokweqile, i-electrolyte ebhethri iqala ukubila ngamandla, izinga layo liyancipha futhi nobuningi buyashintsha. Amapuleti ngokwengxenye asemoyeni, ngenxa yalokho amandla namanje ancishisiwe. Isithombe esifanayo sibangelwa ukwehluleka kokudluliswa komlawuli we-generator: amandla kagesi kunethiwekhi yebhodi angakhuphukela kumanani aphezulu kakhulu. Lokhu, nakho, kuholela ekuhwamukeni kwe-electrolyte kanye "nokufa" okusheshayo kwebhethri.
Ezimotweni ezinohlelo lokuqala/lokumisa, kusetshenziswa amabhethri akhethekile enziwe kusetshenziswa ubuchwepheshe be-AGM. Le mishini ibiza kakhulu kunejwayelekile. Lapho ushintsha ibhethri, abanikazi bezimoto ngokuvamile bazama ukonga imali, kodwa bakhohlwe ukuthi amabhethri e-AGM ekuqaleni aba nempilo ende, njengoba enzelwe imijikelezo eminingi yokushaja. Ukwehluleka ngaphambi kwesikhathi kwebhethri “elingalungile” elifakwe ezimotweni ezinohlelo lokuqala/lokuma kuyinkambiso echazwa kalula.
