Eqinisweni, khulisa inkulumo-ze yeminye imikhiqizo emisha kanye nobuchwepheshe obusha, futhi kukhona cishe kuzo zonke izimboni. Kodwa lamasango amasha asetshenziselwa ini? Ingakanani inani elikhona? Ngemuva kokuthi umthengi ehlanganiswe nefu, kubonakala sengathi akakhathazeki kakhulu ngalezi zinkinga. Ngizwa nje ukuthi le nto iyinkomo kakhulu.

Namuhla sikhuluma ngobuningi bamandla ebhethri, ukuthi ungakanani umthelela kukhwalithi yezimoto ezihlanzekile zikagesi. Ingabe ukuminyana kwamandla? Okokuqala, simane siqonde ukuthi ukuminyana kwamandla ebhethri kuyinto ethile. Ukuminyana kwamandla kuhlukaniswe kabili, ukuminyana kwamandla esisindo kanye nokuminyana kwamandla evolumu.

Ireferensi yamanje ukuminyana kwamandla esisindo. Ifomula yokubala ithi: isisindo samandla esisindo = umthamo webhethri yesikhulumi / isisindo, iyunithi ngu-WH / kg (Watt / kg); Indlela yokubala yokuminyana kwamandla evolumu iguqula kuphela isisindo sefomula engenhla sibe ivolumu, iyunithi ithi WH / L (watt / ilitha). Kalula nje, ukuminyana kwamandla kuwukuhlola umthamo wokugcina amandla ebhethri.

Futhi ukuhlola okunjalo, kwakungekhona ukunquma izinga lezimoto zikagesi ezinhle noma ezimbi, kodwa inqubomgomo yomthamo wokugcina amandla wenqubomgomo kubhethri ye-lithium enikwe amandla yenkampani. Ngokwezidingo, inkampani idinga ngaphezu kuka-300 watts / kg kunamandla ku-2020 lithium battery monomer, futhi uhlelo lungaphezu kwama-watts angu-260 / kg. Ngokombono wokumaketha, njengoba lokhu kuyindinganiso yokuthuthukiswa kwenqubomgomo, ngokuqinisekile iyathandeka kubathengi, ngakho-ke isibe yi-plummer ohlelweni lokuthengisa izimoto ezihlanzekile zikagesi.

Ukuhlolwa kokuminyana kwamandla akuvuthwanga ngokuphelele, futhi ukuhlolwa kokuqina kwamandla akulungile ngokuphelele, ngoba lokhu kanye nezithakazelo zamabhizinisi ezimoto kuxhumene ngqo. Sesike sasho ngaphambili, futhi inqubomgomo izodinga ukuminyana kwamandla, futhi amandla angelinye lamazinga okubhekisela kuwo mayelana nokusekelwa kwamandla amasha. Uma kuphezulu ukuminyana kwamandla, kuyanda ukuxhaswa kwamandla amasha.

Lokhu kuye kwaholela emncintiswaneni wezempi ebhethri ye-lithium yamandla, futhi kusenamakati amaningi. Ukuze uqonde ukuthi inkampani yezimoto ithuthukisa kanjani ukuminyana kwamandla, kufanele usho kusuka kufomula manje: isisindo samandla wesisindo = isiteji sokukhipha amandla ebhethri / isisindo. Ukwandisa le fomula, kunezindlela ezimbili, indlela eqondile kakhulu, eyodwa ukukhulisa umthamo webhethri, kanti enye iwukunciphisa isisindo sebhethri.

Indlela yokukhulisa umthamo webhethri kuwumkhuba kanembeza. Ziningi izindlela zokwandisa umthamo, futhi iningi livela ezintweni zebhethri. Njengamanje, ibhethri ye-lithium-ion enezinhlangothi ezintathu iwuhlobo lwebhethri ye-lithium enamandla kakhulu e-China, kuyilapho ibhethri yensimbi ye-phosphate ishesha kakhulu.

Kodwa-ke, umkhuba kanembeza awunayo into enhle ezandleni zomuntu ongenampilo, ukuze kwandiswe umthamo webhethri, abanye abakhiqizi baye behlisa izidingo zokuzinza kwebhethri, futhi izingozi zokuphepha zanda. Ngakho-ke, kukhona abangaphakathi embonini, futhi umthamo webhethri muhle kakhulu, sizothinta ukuphepha kwezimoto zikagesi. Enye indlela ukunciphisa isisindo sayo yonke ibhethri ye-lithium yamandla, empeleni engelapheki.

Amanye amabhethri e-lithium ekhwalithi ephezulu aneseli ehlukile yebhethri ngalinye ukuze ahluleke ukuthinta lonke iphakethe lebhethri uma lehluleka. Ukunciphisa isisindo sebhethri ye-lithium yamandla, ukugijima kokuqala yilawa maseli. Ukwakha into entsha kuyenza yehlise isisindo ngaphandle kokuthikameze ukuvikeleka kwebhethri, noma okokusebenza kunciphisa ngokuqondile okubalulekile noma isisindo kodwa kuqine nakakhulu.

Ngakho-ke, kunezindlela eziningi zokwengeza ukuminyana kwamandla. Mayelana namabhizinisi ezimoto, izinto zokusika ziyindlela yokuwina, futhi izindaba zokuphepha zingamathani angama-60. Esimeni lapho ukwakheka nokokusebenza kwebhethri kungenayo imfuneko efanayo, amandla okuminyana kwamandla aphezulu asezingeni elifanelekile, elihle noma elihle kakhulu, futhi abathengi abanayo indlela yokulinganisa.

Bhala okokugcina kwangempela, esikalini sempilo yebhethri, indlela elula nengenanhlonipho, noma ubuke ngqo isamba somthamo webhethri. Uma ufuna ukucabangela ukuphepha kokuphepha kwebhethri, ikhwalithi yemoto, imoto kagesi iseyipeni endaweni yonke yobuchwepheshe obuvulekile, indawo yonke yezindleko zokukhiqiza ayinkulu. Ukukhuluma ngokuqondile, ngokuvamile, noma intengo yemoto inquma okuhle.

Uma ingxenye efanele ingathuthukisa ukulunga kwamazinga okuhlola imoto kagesi, kuhle kakhulu ngenqubekelaphambili yobuchwepheshe obushukumisayo kanye nokuvikelwa kwamalungelo abathengi. U-Sun Wei, umcwaningi we-Institute of Science, izwe lami, uhlanganise futhi wachaza kabanzi embikweni wobuchwepheshe bokubuyisela ibhethri ye-lithium-ion. Ukholelwa futhi ukuthi ukunaka ukugaywa kabusha kwebhethri ye-lithium-ion kusuka kumbono wokuphepha kokuhlinzekwa kwezinsiza kanye nokungcoliswa kwemvelo.

Ngokuzayo, ukuhlelwa kwemboni kuyahlanganiswa, kanye nokuthuthukiswa kobuchwepheshe kobuchwepheshe bemishini kanye namazinga okuvimbela nokulawula ukungcola, kuyilapho kuqondisa imigomo yezimboni ukuvimbela izimakethe zendawo ekushiseni ngokweqile, okubangela ukushintshashintsha kwezimakethe. UCui Dongshu, uchwepheshe wocwaningo kuchwepheshe wocwaningo lwemakethe yezimoto e-China, uveze ukuthi inkampani eqinile yebhethri ibambe ukuthuthukiswa kwemboni yezimoto zamandla amasha, futhi ukuthuthukiswa kwebhethri lesikhathi esizayo kulethe inkinga enkulu kanye nenselelo, ngakho ukugaywa kabusha kwebhethri Ngokusetshenziswa kwezinsiza kufanele kwenziwe izinkampani zamabhethri (kunokuba izinkampani zezimoto), ikakhulukazi izinkampani zabaholi bebhethri. U-Yang Qingyu, umeluleki omkhulu wezwe lami I-Battery Alliance, i-Beijing Green Zhihui Energy Technology Research Institute, u-Yang Qingwei, uveze ukuthi uchungechunge lwemboni yokuvuselela ibhethri ye-lithium eguquguqukayo luhlanganisa ukubuyiswa kwebhethri, ukusetshenziswa kwezitebhisi, ukwelashwa kusengaphambili, ukusetshenziswa kabusha kwezinto ezibonakalayo, njll.

, ukuhlanganiswa kochungechunge lwezimboni kuzoba yi-Development Trend, kodwa kunezithiyo zobuchwepheshe, imigoqo yedatha, futhi ukuhlelwa kwempahla kufanele kuqinise ukubambisana okukhuphukayo phakathi kwemboni. Kuyaqondakala ukuthi ngenkambiso yokuthuthukiswa kwesivinini esikhulu semakethe yezimoto zamandla amasha, ibhethri ye-lithium-ion yemoto yamandla entsha ingene enkathini ye-scrap enkulu. Ngakolunye uhlangothi, inkinga yokungcola nokungcoliswa kwemvelo, ngakolunye uhlangothi, ubuchwepheshe bokubuyisela kanye namazinga webhethri ye-lithium-ion, njll.

Ziningi izinkinga mayelana nezingxoxo ezengeziwe. U-Sun Xiaofeng, iPhini Likamongameli weBeijing Science and Technology, efingqa, ibhethri ye-lithium-ion enamandla ehilelekile kuzinsiza, ubuchwepheshe, imakethe, nezinqubomgomo, njll., iwubunjiniyela obuhlelekile, ochwepheshe kanye nezazi bazokwamukela i-Beijing Science and Technology Association izonikezwa kuhulumeni.

Ukubonisana ngesinqumo sesithenjwa. .
