Inselele Yebhakede Leqhwa! Ingabe izinga lokushisa eliphansi lizokwehlisa umthamo webhethri?

Ezincwadini ezinemifanekiso ezisetshenziswa amadivaysi amaningi edijithali, singabona izinga lokushisa lokusebenza lomkhiqizo, iningi lawo elingama-degree Celsius angu-10 no-40 degrees Celsius. Siyazi ukuthi ibhethri ye-lithium iphephile ukusebenza ngesikhathi sokushaja nokushisa, futhi izinga lokushisa eliphansi le-electrolyte elibekwe endaweni yokushisa ephezulu kanye nemvelo yokushisa ephansi Ukusebenza kwangaphakathi kwamabhethri e-lithium kuphansi, okuthinta ukusetshenziswa kwabasebenzisi, futhi kubangele ngisho ne-low- ukwehluleka kwezinga lokushisa kwebhethri.

Uma usebenzisa omakhalekhukhwini abaningi noma amabhethri ebusika obusenyakatho, ungathola ukuthi lapho izinga lokushisa liphansi, ukusebenza kwebhethri kuyawohloka, ngisho nemikhiqizo kagesi ayikwazi ukuvulwa. Ake sibheke ukusebenza kwebhethri emazingeni okushisa aphansi.

Ibhethri elibaluleke kakhulu esilisebenzisa manje ibhethri le-lithium. Ngokombono, umphumela wokushisa wamabhethri e-lithium ahlukene ngokuyisisekelo uyafana. Ukuze siqhathanise umthelela wezinga lokushisa eliphansi ngendlela enembile, sikhethe ukuhlola ukusebenza okungalinganisa ibhange lamandla.

Ukunikezwa kwamandla okuphathekayo kubhekene nokuhlolwa kwezinga lokushisa eliphansi

Uma kucatshangelwa amabhethri ahlukene asetshenziswa emithonjeni yamandla eselula, siphinde sakha imithombo emibili yamandla ebhethri ye-lithium esetshenziswa kakhulu ukuze kwenziwe amasampula edatha, okuhlanganisa amabhethri e-lithium ephakethe ethambile (aziwa kakhulu).

Ibhethri inempilo ende yesevisi ezingeni lokushisa legumbi

Ukuze kube lula ukuqhathanisa okulandelanayo kokulinganisa, siqale sihlole ukusebenza kokukhishwa kwamandla kagesi weselula ezingeni lokushisa legumbi. Njengedatha yeqembu lokulawula, izinga lokushisa lendawo yokukhipha leqembu lokulawula lingu-30 ℃.

Sicela uqaphele ukuthi silapha ukuze siqhathanise ukusebenza kwebhethri elifanayo kumazinga okushisa ahlukene. Amabhange kagesi amabhethri ahlukene esiwahlolile awakakamiswa afane. Ngakho-ke, lezi zinhlobo ezimbili zamaseli aziqhathaniseka.

Khipha ijika lebhethri le-lithium eligqoke ngokuthambile ekamelweni lokushisa

Kungabonakala ukuthi ibhethri ye-lithium ye-soft-pack izinzile ekamelweni lokushisa elingu-30 ° C, i-voltage iyonke imayelana ne-4.95V, futhi amandla okukhishwa kwereferensi angama-35.1 watt-amahora.

18650 ijika lokukhipha izinga lokushisa lebhethri

Ibhethri le-18650 linokushintshashintsha okuncane ekamelweni lokushisa, i-voltage iyonke ingaphezulu kuka-4.9V, futhi ukuzinza kuhle. Amandla okukhipha isithenjwa angama-29.6 watt-amahora.

amandla eselula ekamelweni lokushisa

Kungabonakala ukuthi kokubili kunokusebenza okuhle kakhulu ekamelweni lokushisa, futhi ukukhipha okuzinzile ekamelweni lokushisa kunganikeza isiqinisekiso esihle kakhulu sempilo yebhethri. Yebo, lokhu futhi ukucaciswa kokuhlela kanye nesicelo samandla eselula namabhethri. Isinyathelo esilandelayo ukuhlola ukusebenza kokukhipha kwebhethri kumazinga okushisa aphansi.

indawo yokuqandisa ucezu lwekhekhe

0℃ izinga lokushisa elivamile lengxube yamanzi eqhwa, futhi izinga lokushisa okufanele libonwe ngaphambi kobusika enyakatho yezwe lami. Siqale sahlola indlela yokukhishwa kwamandla kagesi ku-0°C.

Umthombo wokugeleza kwamanzi usengxubeni yamanzi eqhwa

Nakuba izinga lokushisa elingu-0℃ liyizinga lokushisa eliphansi le-ambient, lisengaphakathi kwebanga lokushisa elisebenzayo lebhethri, futhi ibhethri kufanele likwazi ukusebenza ngendlela evamile. Sifaka ukunikezwa kwamandla kamakhalekhukhwini engxubeni yamanzi e-ice, sikhipha ngemva kokuthi izinga lokushisa lizinzile, sengeza iqhwa ukuze silondoloze izinga lokushisa, futhi ekugcineni sikhiphe idatha yokukhipha.

Ijika lokukhishwa kwebhethri le-lithium eligqoke ngokuthambile ekamelweni lokushisa kanye nendawo eyiziro

Kungabonakala ku-curve yokukhipha ukuthi ijika lokukhipha ibhethri ye-lithium ye-soft-pack ishintshile kakhulu, wonke ama-voltages nesikhathi sokukhipha sincishisiwe, futhi amandla okukhipha ancishisiwe abe ngama-watt-amahora angu-32.1.

Izinga lokushisa legumbi lebhethri elingu-18650 kanye nejika lokukhipha imvelo elinguziro

Ijika le-18650 lokukhipha alithinteki kakhulu, kodwa amandla okuqala kagesi ayanda, kodwa umthamo uthinteka kakhulu, kuze kufike ku-16.8 Wh.

Kungatholwa ukuthi ku-0°C, ibhethri alithinteki kangako futhi ububanzi bokushintsha i-voltage abukhulu, futhi inganikezwa umsebenzisi ukuze ayisebenzise okuvamile. Esimeni esinjalo, amandla ebhethri akufanele avikelwe ngokukhethekile.

Ukukhishwa kwekhabhoni ezindaweni ezibandayo kuyathinteka

khipha 20 degrees Celsius isimo sezulu esibanda kakhulu, futhi imisebenzi yangaphandle incipha kakhulu, kodwa ukusebenza kwebhethri nakho kubaluleke kakhulu kule ndawo enzima. Leli izinga lokushisa eliphansi esilihlolile.

Ijika lokukhipha lebhethri le-lithium elithambile emazingeni okushisa ahlukene

Ku-20°C, ukusebenza kokukhishwa kwebhethri ye-lithium ene-soft-clad kuyathinteka, futhi ijika lokukhipha libonakala ngokusobala li-jitter.
