Yini imodyuli yebhethri ye-lithium?

Ukubuka konke kwamamojula webhethri

Amamojula webhethri ayingxenye ebalulekile yezimoto zikagesi. Umsebenzi wabo ukuxhuma amaseli ebhethri amaningi ndawonye ukwakha wonke ukuhlinzeka amandla anele ezimoto zikagesi asebenze.

Amamojula webhethri yizinto zebhethri ezakhiwa amaseli webhethri amaningi futhi ayingxenye ebalulekile yezimoto zikagesi. Umsebenzi wabo ukuxhuma amaseli webhethri amaningi ndawonye ukwakha wonke ukuhlinzeka amandla anele ezimoto zikagesi noma imisebenzi yokugcina amandla. Amamojula webhethri akuwona kuphela umthombo wamandla wezimoto zikagesi, kodwa futhi nelinye lamadivayisi awo abaluleke kakhulu ukugcinwa kwamandla.

Ukuzalwa kwamamojula webhethri

Ngokombono womkhakha wemishini yokukhiqiza imishini, amabhethri eseli elilodwa anezinkinga ezinjengezakhiwo ezingezinhle zemishini kanye nezindawo zokuxhumana zangaphandle ezingenabungane, ikakhulukazi kufaka phakathi:

1. Isimo sangaphandle esingokomzimba afana nosayizi nokubukeka kungazinzi, futhi sizoshintsha kakhulu ngenqubo yokujikeleza kwempilo;

2. Ukuntuleka kokufakwa okulula nokuthembekile kwemishini kanye nokulungisa isikhombimsebenzisi;

3. Ukuntuleka kokuxhumeka okulula kokukhipha kanye nesimo sokuqapha isimo;

4. Ukuvikelwa okubuthakathaka kwemishini nokuvikelwa.

Ngoba amabhethri eseli elilodwa anezinkinga ezingenhla, kuyadingeka ukwengeza ungqimba ukuze ushintshe futhi uzixazulule, ukuze ibhethri lingahlanganiswa futhi lihlanganiswe nemoto yonke kalula. Imodyuli eyakhiwe ngamabhethri ambalwa kuya kwayishumi noma angamashumi amabili, anesimo sangaphandle esizinzile, esikahle futhi athembekile, okuphumayo, isikhombimsebenzisi esibonakalayo, nokuvikelwa okuthuthukisiwe nokuvikelwa okuthuthukisiwe kungumphumela walokhu kukhethwa kwemvelo.

Imodyuli ejwayelekile yamanje ixazulula izinkinga ezahlukahlukene zamabhethri futhi inezinzuzo ezilandelayo ezilandelayo:

1. Kungakuthola kalula ukukhiqizwa okuzenzakalelayo okuzenzakalelayo futhi kunokusebenza kahle kokukhiqiza okuphezulu, kanye nekhwalithi yomkhiqizo nezindleko zokukhiqiza kulula ukulawula;

2. Kungakha izinga eliphakeme lokuma okujwayelekile, okusiza ukunciphisa izindleko eziphakeme kakhulu ukukhiqiza futhi kuthuthukise ukusebenza kahle kokukhiqiza; Izindawo ezijwayelekile kanye nokucaciswa zilungele ukuncintisana okugcwele kwemakethe nokukhethwa kwezindlela ezimbili, futhi kugcinwe ukusebenza okungcono kokusetshenziswa kwe-cascade;

3. Ukwethenjwa okuhle kakhulu, okunganikeza ukuvikela okuhle kwemishini nokufakwa kwamabhethri kuwo wonke umjikelezo wokuphila;

4. Izindleko eziphansi eziphansi ezingavuthiwe ngeke zibeke ingcindezi enkulu kakhulu kwizindleko zokugcina zohlelo lokusebenza kwamandla;

I-5. Ubuncane beyunithi yeyunithi elincane lincane, elinomthelela omkhulu ekunciphiseni izindleko ngemuva kokuthengisa.

Isakhiwo sokwakhiwa kwemodyuli yebhethri

Isakhiwo sokwakhiwa kwemodyuli yebhethri ngokuvamile kufaka phakathi iseli lebhethri, uhlelo lokuphathwa kwebhethri, ibhokisi lebhethri, isixhumi sebhethri nezinye izingxenye. Iseli yebhethri yingxenye eyisisekelo yemodyuli yebhethri. Ihlanganiswe namayunithi ebhethri amaningi, imvamisa ibhethri le-lithium-ion, elinezici zobuningi obuphezulu bamandla, izinga lokuzenzela eliphansi nempilo yenkonzo ende.

Uhlelo lokuphathwa kwebhethri lukhona ukuqinisekisa ukuphepha, ukuthembeka kanye nempilo ende yebhethri. Imisebenzi yayo eyinhloko ibandakanya ukuqapha isimo sebhethri, Ukulawulwa kokushisa kwebhethri, ukweqiwa kwebhethri / ukuvikelwa kokukhipha, njll.

Ibhokisi lebhethri liyigobolondo elingaphandle lemodyuli yebhethri, elisetshenziselwa ukuvikela imodyuli yebhethri kusuka endaweni yangaphandle. Ibhokisi lebhethri livame ukwenziwa ngensimbi noma ngezinto zepulasitiki, ngokumelana nokugqwala, ukumelana nomlilo, ukumelana nokuqhuma kwezinye nezinye izici.

Isixhumi sebhethri siyingxenye exhuma amaseli ebhethri amaningi aphelele. Imvamisa yenziwa ngezinto zethusi, ngokuvuselelwa okuhle, ukugqoka ukumelana nokuphikiswa kokugqwala.

Izinkomba Zokusebenza Kwebhethri

Ukumelana kwangaphakathi kusho ukumelana kokugeleza kwamanje ngebhethri lapho ibhethri lisebenza, okuthintwa yizinto ezifana nezezinto zebhethri, inqubo yokukhiqiza kanye nesakhiwo sebhethri nesakhiwo sebhethri. Ihlukaniswe ekumelaneni kwangaphakathi kwe-Ohmic nokumelana kwangaphakathi kwe-polarization. Ukumelana kwangaphakathi kwe-Ohmic kwakhiwa ngokumelana nokuxhumana kwezinto ze-electrode, ama-electrolyte, ama-diaphragms nezingxenye ezahlukahlukene; Ukumelana kwangaphakathi kwe-polarization kubangelwa yi-Electrochemical Polarization kanye nombala womehluko wokuhlushwa umehluko.

Amandla athile - amandla ebhethri ngevolumu ngayinye noma isisindo.

Ukushaja nokukhipha amandla - isilinganiso sezinga elithile amandla kagesi asetshenziswa yibhethri ngesikhathi sokushaja aguqulwa abe amandla amakhemikhali azowagcina ibhethri.

I-Voltage - umehluko ongaba khona phakathi kwama-elekthrothi amahle nengemuhle webhethri.

Vula i-Volcuity Voltage: The Voltage yebhethri lapho kungekho mjikelezo wangaphandle noma umthwalo wangaphandle oxhunyiwe. I-Open Circuity Voltage inobudlelwano obuthile nobuningi bebhethri, ngakho-ke i-voltage yebhethri ivame ukukalwa ukulinganisa umthamo webhethri. I-Voltage esebenzayo: Umehluko ongaba khona phakathi kwama-elekthrothi amahle nengemuhle webhethri lapho ibhethri lisesimweni sokusebenza, okungukuthi, lapho kudlula khona lapho. I-Det Cut-off-off-off-off-off Ukushaja i-voltage ka-cut-off

Izinga lokukhokhisa nokwehla - sula ibhethri nge-1h, okungukuthi, 1c. Uma ibhethri le-lithium lilinganiselwa ku-2Ah, khona-ke i-1C yebhethri ingu-2A no-3c ngu-6a.

Ukuxhumana okuhambisanayo - umthamo wamabhethri ungandiswa ngokuwaxhuma ngokufana, kanye namandla = umthamo webhethri elilodwa * Inani lokuxhunyaniswa okufanayo. Isibonelo, imodyuli ye-Chanan 3P4S, umthamo webhethri elilodwa ngu-50h, khona-ke amakhono we-module = 50 * 3 = 150h.

Ukuxhumeka kochungechunge - Amandla kagesi angakhushulwa ngokuwaxhuma ngochungechunge. I-Voltage = I-voltage yebhethri elilodwa * inani lezintambo. Isibonelo, imodyuli ye-Chanan 3P4S, i-voltage yebhethri elilodwa ngu-3.82V, bese-module Voltage = 3.82 * 4 = 15.28V.

Njengengxenye ebalulekile ezimotweni zikagesi, amamojula webhethri we-Lithium Lithium adlala indima ebalulekile ekugcinweni nasekunikezeni amandla kagesi, ukuhlinzeka amandla, nokuphatha nokuvikela amaphakethe ebhethri. Banomehluko othile ekwakhiweni, ekusebenzeni, izici kanye nesicelo, kepha bonke banomthelela obalulekile ekusebenzeni nasekuthembekeni kwezimoto zikagesi. Ngokuthuthuka okuqhubekayo kobuchwepheshe kanye nokwanda kwezicelo, amamojula webhethri we-Lithium azoqhubeka nokuthuthukisa futhi enze iminikelo enkulu ekunyuselweni nasekudumeni kwezimoto zikagesi.
