Okokuqala, ibhethri ye-lithium-ion enamandla kakhulu ingamandla amakhulu, ihlangabezana nezingozi, ibangela ukuphuma kwamandla okushisa, kanye nokusabela okukhulu kwangaphakathi ebhethrini. Esikhathini esifushane, amandla amaningi kakhulu akukho ndawo yokukhulula, kuyingozi kakhulu. Ikakhulukazi kumakhono okuphepha, abaphathi abakwazi ukuthuthukisa, wonke umthamo webhethri kufanele uvinjelwe.

Okwesibili, amandla ahlanganiswe yizindlu zebhethri ze-lithium-ion, lapho kwethulwa izingozi, izicishamlilo, ama-ejenti okucima umlilo awakwazi ukuthinta, amandla awaveli enhliziyweni, angakwazi ukuhlukanisa indawo yesehlakalo lapho ukuhlaselwa, ibhethri ibuyile, ukuvutha kwamandla kumisiwe. Yiqiniso, ngenxa yezizathu zokuphepha, ibhethri ye-lithium-ion ngaleso sikhathi ihlele amasu amaningi okuphepha. Thatha ibhethri eliyisilinda njengesibonelo.

I-valve yokuphepha, lapho ukusabela kwangaphakathi kwebhethri kudlula ubukhulu obujwayelekile, izinga lokushisa liyakhuphuka, futhi lihambisane nokukhiqizwa kwegesi ye-sub-reverb, ukucindezela kufika enanini elihleliwe, i-valve yokuphepha ivuliwe ngenkuthalo, ikhishwe ekucindezelweni. Uma kuvulwa ivalvu yokuphepha, ibhethri alisebenzi nhlobo. I-Thermistor, amanye amaqoqo afakwe i-thermistor.

Uma ukuchichima kukhona, ngemva kokufinyelela ekushiseni okuthile, ukumelana kuye kwanda kancane, ukwehla kwamandla wesifunda, ukwanda okuqhubekayo kokushisa kokuvinjelwa. I-fuse, ibhethri ifakwe i-fuse enomsebenzi we-overflow-fuse, uma ingozi ye-overcurrent, isekethe inqanyuliwe, kanye nokuhlasela kokufudumala.

Ngalesi sikhathi, kuyadingeka ukubhekana nenkinga kanye nokujwayelekile. Okuhlangenwe nakho kwethu kwansuku zonke ukuthi amabhethri amabili omile, okuhle nokubi kuxhunyiwe, futhi ithoshi lingakhanya, futhi noma ubani ongasebenzi ndawonye. Futhi ukusetshenziswa okukhulu kwebhethri ye-lithium-ion, isimo asilula kangako.

Amapharamitha ebhethri ye-lithium-ion awabelani ngomthamo, ukumelana kwangaphakathi, ne-voltage evulekile. Intambo yebhethri engajwayelekile isetshenziswa ndawonye, ​​izokwethula inkinga elandelayo. I-1) Ukulahlekelwa umthamo, i-cell monomer yakha iphakethe lebhethri, umthamo uhambisana nesimiso sebhakede lezinkuni, umthamo webhethri omubi kakhulu unquma lonke iphakheji yebhethri.

Ukuze uvimbele ukugcwala kwebhethri ngokweqile, i-logic yebhethri ivunyelwe: ukukhipha, lapho i-voltage ye-monomer ephansi kunazo zonke ifinyelela ku-voltage cutoff yokukhipha, lonke iphakethe lebhethri liyeka ukukhipha; lapho ishaja, lapho i-voltage ye-monomer ephakeme kakhulu ithinta i-cutoff yokushaja, Misa ukushaja. Thatha amabhethri amabili ngochungechunge. Umthamo webhethri owodwa 1c, omunye umthamo ubude obungu-0.

9c. Ubudlelwano bochungechunge, amabhethri amabili adlula i-current giant current. Uma ishaja, ibhethri elinomthamo omncane kufanele lichichime ngokugcwele, lifinyelele umnqamulajuqu wokushaja, isistimu ayisaqhubeki nokushaja.

Lapho ukukhishwa kukhishwa, ibhethri lincane, futhi kufanele kuqala libeke ukukhanya, futhi uhlelo lungasetshenziswa, futhi uhlelo kufanele lumise ukukhipha. Ngale ndlela, amaseli ebhethri anamandla amancane ahlala eshajwa ngokweqile, futhi ibhethri elinomthamo omkhulu belilokhu lisetshenziswa ngokwengxenye umthamo. Umthamo ophelele wephakethe lebhethri uyingxenye yesimo sokungenzi lutho 2) Ilahlekile, efanayo, iphakethe lebhethri, ingqikithi yebhethri kunqunywa inani elifushane kakhulu lempilo.

Ibhethri elikhulu kakhulu, ibhethri elifushane kakhulu, ibhethri elincane. Ibhethri elinamandla amancane, isikhathi ngasinye sigcwele ukukhiqizwa ngokweqile, okubanzi, kwafika kakhulu enanini lokuzalwa. Ukuphela kwenani lamaqoqo amaseli ebhethri, isethi yamaqoqo athengiswayo, alandelwa umhlaba.

I-3) Ukumelana kwangaphakathi kuyanda, ukumelana okuhlukile kwangaphakathi, ukugeleza okwamanje okufanayo, ukumelana kwangaphakathi kweseli kagesi kuqhathaniswa kakhulu. Izinga lokushisa lebhethri liphezulu kakhulu, futhi isivinini sokuwohloka komthethosisekelo siyasheshiswa, futhi ukumelana kwangaphakathi kuzokwanda nakakhulu. Ukumelana kwangaphakathi nokwenyuka kwezinga lokushisa, kuhlanganisa ipheya lempendulo engemihle, ukuze ibhethri likwazi ukumelana nangaphakathi liwohloke.

Imingcele emithathu engenhla ayizimele ngokuphelele, futhi ukumelana kwangaphakathi kwezinga lokuguga kukhulu kakhulu, futhi ukuncishiswa kwamandla kungaphezulu. Chaza ngokwehlukana, nje ufuna ukuliveza ngokucacile ithonya labo. Indlela yokubhekana nokuhluleka kwamaseli angabonakali, kwenziwa ngenqubo yokucubungula, ejulile phakathi nenqubo yesicelo.

Ibhethri elisephaketheni lebhethri elifanayo alinamandla, futhi alinamandla. Izinga lokuhlukanisa phakathi kwama-agumenti phakathi kwamayunithi amaseli, futhi linyusa izinga lokuguga. Ngaleso sikhathi, unjiniyela akakwazanga ukusebenza ndawonye nebhethri le-monomer.

Ukuhlunga kwebhethri ye-Monomer, ngemva kweqembu, yisikhathi sokuphatha, futhi inombolo encane yokucubungula ibhethri yesikhathi esingavamile kuyalinganiswa. 1) Usayizi wamaqoqo ahlukene wamaqoqo, ngokwethiyori awahlangani. Ngisho noma iqoqo elifanayo likhethiwe, faka amapharamitha kuphakethe lebhethri, kuphakethe lebhethri elifanayo.

Inhloso yokuhlunga ukukhetha ibhethri elifana namapharamitha. Indlela yokuhlunga sekuxoxwe ngayo iminyaka eminingi, ukuhlukaniswa okuyinhloko kokuhlunga okumile kanye nokuhlunga okuguquguqukayo izigaba ezimbili. Ukuhlunga okungaguquki, ukukhethwa kwamapharamitha wesici afana nogesi wesekethe ovulekile, ukumelana kwangaphakathi, umthamo webhethri, khetha imingcele yenqubomgomo, wethula ama-algorithms ezibalo, setha ukucaciswa kokukhetha, futhi ekugcineni uhlukanise iqoqo elifanayo lama-cores kagesi abe ngamaqembu amaningana.

Ukukhetha okunamandla ukukhethwa kwezici eziboniswa ngesikhathi sokushaja nokukhipha. Abanye bakhetha inqubo eqhubekayo yokushaja ingcindezi yamanje, kanti enye ishaja yokushaja kwe-pulse kanye nenqubo yokukhipha, ezinye iziqhathanise phakathi kokuhlobana kwejika lokushaja nokukhipha. Inhlanganisela eguquguqukayo ikhethiwe, futhi ukuqoqa kokuqala kwenziwa ngokukhetha okumile.

Ngalesi sisekelo, ukukhethwa okuguquguqukayo kwenziwa, okungaphezu kweqembu, kodwa ukunemba kuphakeme, kodwa izindleko zizokhuphuka ngokufanele. Lokhu ukubonakaliswa okuncane kwesikali sokucubungula ibhethri le-lithium-ion esiguqukayo. Ukuthunyelwa kwenani elikhulu kwenza abakhiqizi benze ukuhlunga okuhlungwe kakhulu, bathole iphakethe lebhethri.

Uma okukhiphayo kukuncane kakhulu, maningi kakhulu amaphakethe, futhi inqwaba ayikwazi ukuhlonyiswa ngephakethe lebhethri, futhi indlela enhle ayikwazi ukuboniswa. I-2) I-thermal ngeke ifane nokumelana kwangaphakathi, futhi ukushisa akufani. Ukujoyina isistimu eshisayo kungalungisa umehluko wezinga lokushisa wephakethe lonke lebhethri ukuze uligcine esikalini esincane.

Khiqiza amaseli ashisayo amaningi, amazinga okushisa amile, kodwa ngeke adonse ibanga ukusuka kwamanye amaseli, futhi izinga lokuwohloka ngeke lilethe ibanga elibalulekile. I-3) Ukulinganisa ukungalingani kwe-module, enye i-voltage yokuphela komgogodla kagesi, njalo kusengaphambili, ifika embundwini wokulawula, okuholela kumthamo omncane. Ukuze kuxazululwe le nkinga, isistimu yokuphatha ibhethri ye-BMS ihlele umsebenzi olinganiselayo.

Umongo othile ungowokuqala ukufinyelela i-voltage yokushaja enqamukile, futhi yonke ingxenye kagesi engumongo kagesi ixega kakhulu, i-BMS iqala ukushaja ukulinganisa, noma ukumelana nokufinyelela, ingxenye yeseli ye-voltage ephezulu, noma idlulise ukudluliswa kwamandla, ikubeka Ibhethri le-voltage ephansi. Ngakho, umnqamulajuqu wokushaja uyakhululwa, inqubo yokushaja iqala kabusha, futhi iphakethe lebhethri lishajwa ngamandla engeziwe.
