1 Ngingabiza kanjani "ishaja esheshayo" lapho ishaja? Sikhokhisa isikhalazo esiyisisekelo: 1) Inkokhelo iyashesha; &39;2) Ungayithinti impilo yami yebhethri; 3) Zama ukonga imali, ingakanani imali kagesi ekhishwayo, zama ukuyishaja ebhethrini lami. Ngakho ungashayela ngokushesha kangakanani? Azikho izincwadi ezijwayelekile ezinikeza amanani athile, okwesikhashana sibhekiswa enanini lemikhawulo eshiwo kunqubomgomo yoxhaso edume kakhulu. Ithebula elilandelayo yizinga elisha lokuxhaswa kwemoto yomgibeli wamandla ka-2017.

Kuyabonakala ukuthi izinga lokungena elisheshayo liyi-3C. Eqinisweni, ezingeni loxhaso lwezimoto zabagibeli, azikho izidingo zokubonisa. Kusukela ezintweni ze-propaganda zemoto yomgibeli jikelele, ungabona ukuthi wonke umuntu angagcwaliswa nge-80% angasetshenziswa njengenkokhelo esheshayo, futhi azothuthukiswa.

Ngakho-ke, imoto yomgibeli engu-1.6c ingaba izinga lokungena Inani lereferensi Yenkokhelo. Ngokwalo mbono, ukukhushulwa imizuzu engu-15 kugcwele 80%, okulingana 3.

2C. 2 ukushaja okusheshayo ibhodlela? Kulo mongo, izinhlangothi ezifanele zilandela izihloko eziphathekayo, ezifaka amabhethri, amashaja, nezindawo zokusabalalisa amandla. Sixoxa ngokushajwa okusheshayo, sicabanga ngokuqondile ukuthi ibhethri izoba nezinkinga.

Eqinisweni, ngaphambi kokuba ibhethri libe nezinkinga, eyokuqala yinkinga yomshini wokushaja nemigqa yokusabalalisa. Sibalule inqwaba yokushaja ye-TSLA, igama layo yinqwaba yokushaja, amandla ayo angu-120KW. Ngokusho kwemingcele ye-Tslamodels85D, 96S75P, 232.

5ah, i-403V ephakeme kakhulu, i-1.6C ihambelana namandla adingekayo aphezulu ngu-149.9kW.

Kuyabonakala lapha ukuthi kukhona ukuhlolwa kwenqwaba yokushaja yemoto kagesi, 1.6C noma imizuzu engama-30. Ngamazinga kazwelonke, akuvunyelwe ukusetha isiteshi sokushaja ngokuqondile kunethiwekhi yokuqala yamandla okuhlala.

Inqwaba engu-1 egcwala ngokushesha amandla kagesi asetshenzisiwe idlule ugesi wezindlu eziyishumi nambili. Ngakho-ke, zombili iziteshi zokushaja kufanele zimise i-transformer engu-10kV ngokuhlukana, futhi inethiwekhi yokusabalalisa yesifunda ayilona inani elisha lesiteshi esincane esingu-10kV. Labe selisho ibhethri.

Ingabe ibhethri lingakwazi ukuthwala izidingo zokushaja okungu-1.6C noma okungu-3.2C, lingabukwa ngemibono emibili ye-macro ne-micro.

3 Isihloko sethiyori yokushaja ngokushesha yethiyori yokushaja ngokushesha ibizwa ngokuthi "ithiyori yokushaja okusheshayo e-Macroable" ngoba umthamo wokushaja osheshayo webhethri onqunywa ngokuqondile ubunjalo, i-microstructure, izithako ze-electrolyte zento yangaphakathi ye-electrode e-positive kanye ne-negative yamabhethri e-lithium ion. Izengezo, izakhiwo ze-diaphragm, njll., okuqukethwe kulawa mazinga amancane, sibekwe okwesikhashana ngaphandle kwebhethri, sibona ukushajwa okusheshayo kwamabhethri e-lithium-ion.

Ukuba khona kwebhethri ye-lithium-ion, ukushaja kwamanje okuhle kakhulu ngo-1972 usosayensi wase-US u-Jamas uphakamisa ukuthi ibhethri linejika lokushaja elingcono kakhulu ngesikhathi sokushaja, kanye ne-Mas San Law yakhe, kufanele kuqashelwe ukuthi lo mbono uhlongozwa amabhethri omthofu we-asidi, ichaza Isimo somngcele wesilinganiso esiphezulu esamukelekayo sokushaja samanje ukuvela kohlobo lwenani elincane, ngokusobala ukusabela okuncane. Kodwa uhlelo lunesixazululo esingcono kakhulu, kodwa yimibuzo ukuthi kunjalo. Ngokukhethekile ebhethrini le-lithium ion, ukuchaza izimo zomngcele wesilinganiso esiphezulu samanje esamukelekayo kungaba nenjongo futhi.

Ngokusekelwe kwezinye iziphetho zemibhalo yocwaningo, inani layo elilungile kusewumkhuba wejika ofana nomthetho. Kuyaphawuleka ukuthi umkhawulo ophezulu wesimo sebhethri ye-lithium-ion, ngaphezu kwezici ze-lithium ion battery monomer, ngaphezu kwezici zezinga lesistimu, njengekhono lokukhipha ukushisa, ukushaja okuphezulu okwamukelekayo okwamanje kwesistimu kuhlukile. Bese sizoqhubeka nokuxoxa phansi nalesi sisekelo.

Incazelo yefomula ka-Maszer: i = i0 * e ^ αt; I-I0 ukushaja kwamanje kwebhethri; α izinga lokwamukela ukushaja; T yisikhathi sokushaja. Inani lika-I0 no-α kanye nohlobo lwebhethri, isakhiwo kanye nentsha nendala. Kulesi sigaba, ucwaningo lwezindlela zokushaja ibhethri lubalulekile ngokusekelwe ejikeni lokushaja elifanele.

Njengoba kuboniswe emfanekisweni ongezansi, uma amandla okushaja edlula leli jika lokushaja elifanele, hhayi izinga lokushaja kuphela elingenakwenyuka, kodwa lizongeza ubuningi bebhethri; uma ingaphansi kwaleli jika lokushaja elingcono kakhulu, nakuba ingeke ilimaze ibhethri, izonweba isikhathi sokushaja, inciphise ukusebenza kahle kokushaja. Ukucaciswa kwalo mbono kuhlanganisa amaleveli amathathu, okungohambo lwe-Masz: 1 nganoma isiphi isikhathi esinikiwe sokukhipha, umthamo wamanje wokushajwa kwebhethri ebhethrini uhambisana ngokuphambene nomthamo womthamo we-α nebhethri; 2 Mayelana nanoma yikuphi ukukhishwa okunikezwayo Inani lenani, α kanye ne-ID yamanje yokukhipha ilingana; 3 Ibhethri ishajwa ngamanani ahlukene okuchithwa, futhi i-IT yamanje evunyelwe ukushaja (amandla amukelekayo) iyisamba samanje sokushaja esivunyelwe ngezinga lokukhipha ngalinye. Ithiyori engenhla futhi ingumthombo womqondo wokushaja ikhono lokwamukela.

Okokuqala qonda ukuthi yini ukwamukela ukushaja. Ngithole umbuthano futhi angizange ngibone incazelo esemthethweni ehlanganisiwe. Ngokuqonda kwakho, ikhono lokwamukela ukushaja ubukhulu bamanje bokushajwa kwebhethri ngenani elithile lenkokhelo ngaphansi kwezimo ezithile zemvelo.

Umthelela wokwamukeleka usho ukuthi awukho umthelela oseceleni okungafanele ube nawo, awukho umthelela omubi empilweni nasekusebenzeni kwebhethri. Ngaphezu kwalokho, qonda imithetho emithathu. Umthetho wokuqala, ngemva kokuba ibhethri selikhishiwe, ikhono lokwamukela ukushaja kanye nenani lamandla lamanje, ishaja ephansi, ikhono lokwamukela ukushaja liphezulu.

Umthetho wesibili, ngesikhathi sokushaja, ukukhishwa kwe-pulse kungasiza ibhethri ithuthukise inani lamanje lokwamukelwa kwesikhathi sangempela; umthetho wesithathu, ikhono lokwamukela ukushaja lizobekwa phezulu yisimo sangaphambi kokukhokhiswa nokukhipha ngaphambi kokushaja. Uma i-Mas ibuye ifanele amabhethri e-lithium-ion, ukushaja kwe-pulse reverse (igama elithile liyindlela yokushaja esheshayo ye-reflex kulokhu okulandelayo] Ngaphezu kombono we-polarization, kuyasiza ekucindezelweni kokukhuphuka kwezinga lokushisa, i-Massea nayo iyasebenza. Ukusekelwa kwezindlela ze-pulse.

Ngaphezu kwalokho, ngempela, kuyindlela yokushaja ehlakaniphile, okungukuthi, indlela yokushaja ehlakaniphile, okungukuthi, inani lamanje lokushaja belilokhu lishintsha ngenxa yejika le-Mascus lebhethri le-lithium-ion, ukuze ukusebenza kahle kokushaja kukhuliswe emngceleni wokuphepha. 4 Izindlela Ezivamile Zokushaja Ngokushesha Indlela yokushaja yamabhethri e-lithium-ion inezinhlobo eziningi zezinhlobo, ezidingweni zokushaja ngokushesha, izindlela zayo ezibalulekile zihlanganisa ukushaja ukushaya kwenhliziyo, ukushaja kwe-Reflex, nokushaja okuhlakaniphile. Izinhlobo zebhethri ezihlukene, izindlela zokushaja ezisebenzayo azifani ncamashi, futhi lesi sigaba asenzi umehluko othile kulesi sigaba.

Ukushaja kwe-Pulse Lena imodi yokushaja ishayela ezincwadini, futhi isigaba sokushaya kwenhliziyo sinikezwa ngemva kokuthinta ukushaja futhi umkhawulo ophezulu wevoltheji ngu-4.2V, futhi ngokuqhubekayo ungaphezu kuka-4.2V.

Ungasho ubuhlakani bezilungiselelo zayo ezithile zepharamitha, izinhlobo ezahlukahlukene zamaqoqo zinokuhluka. Siyayinaka inqubo yokuqaliswa kwe-pulse. Ngezansi kunejika lokushaja ishayela, futhi kubalulekile ukufaka izigaba ezintathu: ukushajwa kwangaphambili, ukushaja kwamanje okungaguquki kanye nokushajwa kweshayela.

Ishaja ibhethri ngamandla angaguquki ngesikhathi ishajwa njalo, ingxenye yamandla idluliselwa ngaphakathi kwebhethri. Lapho i-voltage yebhethri ikhuphukela ku-voltage yomkhawulo ophezulu (4.2V), faka imodi yokushaja ishayela: ukushaja ibhethri nge-pulse current engu-1C.

I-voltage yebhethri ilokhu ikhuphuka ngokuqhubekayo ngesikhathi sokushaja esingashintshi Tc, futhi i-voltage izokwehla kancane uma ukushaja kuyekiswa. Lapho i-voltage yebhethri yehla ifika ku-voltage yomkhawulo ophezulu (4.2V), ishaja ibhethri ngevelu efanayo yamanje, iqala umjikelezo wokushaja olandelayo, igaywe kabusha kuze kugcwale ibhethri.

Phakathi nenqubo yokushaja ishayela, isivinini se-voltage yebhethri sizohamba kancane, futhi isikhathi sokuma i-T0 sizoba side. Uma umjikelezo wokushaja oqhubekayo wamanje uphansi ngo-5% ~ 10%, kucatshangwa ukuthi ibhethri ligcwele futhi liyaphela ukushaja. Uma kuqhathaniswa nezindlela ezivamile zokushaja, ukushaja kwe-pulse kungashaja nge-current enkulu, futhi ukugxila kwebhethri kubhethri yesitobha kanye ne-ohmic polarization kuzoqedwa, ukuze umzuliswano olandelayo wokushaja uhambe kahle, isivinini sokushaja siyashesha, Izinga lokushisa lincane, lithinta impilo yebhethri, futhi okwamanje lisetshenziswa kabanzi.

Kodwa-ke, ububi bayo busobala: ukunikezwa kwamandla kumsebenzi wokusakaza okulinganiselwe, okwengeze izindleko zendlela yokushaja ishayela. Indlela yokushaja ngezikhathi ezithile, ibhethri ye-lithium-ion, ukushaja ngezikhathi ezithile, indlela kagesi yezikhawu, nezikhathi ezithile, kanye nokushajwa kwe-voltage eguquguqukayo. 1) Ukuguqulwa kwendlela yokudlulisa izikhawu ezidlulayo kuhlongozwe uprofesa wase-Chen Gongjia, eNyuvesi yase-Xiamen.

Ibonakala ngokushintsha ukushaja kwamanje okungaguquki kube intambo ekhawulelwe. Njengoba kuboniswe emfanekisweni ongezansi, isigaba sokuqala sokuguqulwa koshintsho ekushintsheni okokuqala, futhi ibhethri ikhokhiswa ngenani elikhulu lamanje. Lapho i-voltage yebhethri ifinyelela ku-cutoff voltage V0, ukushaja kuyamiswa.

Ngalesi sikhathi, i-voltage yebhethri yehle kakhulu. Ngemva kokugcina isikhathi sokuma, nciphisa amandla okushaja ayaqhubeka nokushaja. Lapho i-voltage yebhethri iphakanyiselwa ku-cutoff voltage V0, ukushaja kuyamiswa, ukuze isikhathi sokutakula (ngokuvamile cishe izikhathi ezi-3 kuya kwezi-4) ukushaja kwamanje kuzonciphisa inani lamanje lokunqamuka kwesethi.

Bese ufaka isigaba sokushaja i-voltage engaguquki, shaja ibhethri ebhethrini kuze kube yilapho ukushaja kuncipha kumkhawulo ophansi, ukuphela kokushaja. Ingqungquthela enkulu yoshintsho enkokhelweni yokushintsha ugesi ikhushulwa ngendlela yesikhashana eye yehla kancane kancane yamanje, okungukuthi, inqubo yokushaja iyasheshiswa, futhi isikhathi sokushaja siyafinyezwa. Kodwa-ke, le sekhethi yemodi yokushaja iyinkimbinkimbi kakhulu, ibiza kakhulu, imvamisa kucatshangelwa kuphela lapho ukushaja okushesha kwamandla aphezulu.

2) Ngokusekelwe ekushintsheni koshintsho kugesi, kunoshintsho enkokhelweni yesikhashana engazweli ugesi. Umehluko phakathi kwakho kokubili yinqubo yokushaja yesiteji sokuqala, futhi ukugeleza kwezikhawu kuyashintshwa kube ngezikhawu. Qhathanisa ukubuka okungenhla (a) kanye nomfanekiso (b), ukushaja okungapheli kwengcindezi ebonakalayo ehambisana kakhulu nejika lokushaja elingcono kakhulu.

Esigabeni ngasinye sokushajwa kwe-voltage engaguquki, ngenxa ye-voltage engaguquki, amandla okushaja ayancipha ngokwemvelo ngokuvumelana nomthetho wenkomba, futhi izinga lokwamukelwa kwamanje kwebhethri liyehla kancane kancane ngokushajwa. I-REFLEX indlela yokushaja esheshayo Indlela yokushaja esheshayo ye-Reflex, eyaziwa nangokuthi indlela yokushaja ekhanyayo noma indlela yokushaja "yokuhona". Umjikelezo ngamunye womsebenzi wale ndlela uhlanganisa ukushaja okuya phambili, ukuhlehla kokukhishwa ngokushesha kanye nezigaba ezintathu.

Ixazulula i-polarization yebhethri ngezinga elikhulu futhi isheshisa isivinini sokushaja. Kodwa ukukhishwa okubuyela emuva kuzofinyeza impilo yebhethri ye-lithium ion. Njengoba kuboniswe esithombeni esingenhla, emjikelezweni ngamunye wokushaja, isikhathi samanje sokushaja esingu-2C singu-10s we-TC, bese kuba ngu-TR1 ka-0.

5 s, isikhathi sokukhipha esihlanekezelwe yi-1 s TD, isikhathi sokuma singu-0.5 s TR2, isikhathi somjikelezo wokushaja ngasinye singu-12s. Njengokushaja, amandla okushaja kancane kancane azoba mancane.

Indlela yokushaja ehlakaniphile okwamanje iyindlela yokushaja ethuthuke kakhulu. Njengoba kukhonjisiwe esithombeni esingezansi, umgomo wayo obalulekile ukusebenzisa ubuchwepheshe bokulawula i-DU / DT kanye ne-DI / DT. Ngokubheka i-voltage yebhethri kanye nokunyuka kwamanje, ibhethri liyashajwa, ukulandelela okuguquguqukayo Umsinga wokushaja owamukelekayo webhethri wenza ukushaja kwamanje kusukela ekuqaleni kwebhethri kwamukeleke.

Izindlela ezihlakaniphile ezinjalo, ngokuvamile ezihlanganiswe nobuchwepheshe be-algorithm obuthuthukisiwe njengenethiwekhi ye-neural nokulawula okungaqondakali, okuqaphela ukulungiselelwa okuzenzakalelayo kwesistimu. 5 Imodi yokushaja Idatha yokuhlola ethinta izinga lokushaja iqhathaniswa nendlela yokushaja yamanje engashintshi kanye nokushaja okuhlanekezela kwenhliziyo. Ukushajwa kwamanje njalo kushajwa ibhethri ngendlela engashintshi kuyo yonke inqubo yokushaja.

Ukushaja kwamanje okungaguquki kungaba nokushaja okukhulu kwamanje, kodwa ngokuhamba kwesikhathi, ukumelana ne-polarization kancane kancane kuvela futhi kwengeze amandla engeziwe, okubangela amandla engeziwe ukushisa, kudla futhi kwenza izinga lokushisa lebhethri likhuphuke kancane kancane. Ukuqhathanisa indlela yokushaja ishayela yokushajwa kwamanje okungaguquki kanye nokushajwa kweshayela ijika elifushane lokushaja elibuyela emuva ngemva kwesikhathi sokushaja. Ifomu eliyisisekelo linjengoba kukhonjisiwe ngezansi.

Enqubweni yokushaja, ukwandisa ama-pulses okukhipha okwesikhashana, ukusetshenziswa kwe-depolarization, ukunciphisa imiphumela yokumelana ne-polarization ngesikhathi sokushaja. Ucwaningo luqhathanise ngokuqondile umthelela wokushaja kwe-pulse kanye nokushajwa kwamanje okungashintshi. Thatha isilinganiso samanje esingu-1c, 2c, 3c, kanye no-4c (c ngenani elilinganiselwe lebhethri), elisetshenziswe kumasethi angu-4 okuhlola okuqhathanisayo.

Inani lamandla akhishwe ngemva kokuba ibhethri seligcwaliswe ngebhethri. Isibalo sibonisa i-wave wave yamanje kanye nebhethri-eceleni kwe-voltage yamanje eshayelayo uma i-chargency charger ingu-2C. Ithebula 1 yidatha yokuhlola yokushaja ishayela egeleza njalo.

Isikhathi se-pulse yi-1s, isikhathi sokushaya kwe-positive ngu-0.9 s, isikhathi se-pulse negative singu-0.1s.

I-ICHAV iyisilinganiso samanje sokushaja, i-QIN iyashajwa; I-qo amandla okukhipha, η ukusebenza kahle okuvela emiphumeleni yokuhlola kuthebula elingenhla, ukushajwa kwamanje okuqhubekayo nokusebenza kahle kokushaja kweshayela kuyalinganiselwa, ukushaya kwenhliziyo kungaphansi kancane kunokwamanje okungaguquki, kodwa ngaphakathi Amandla aphelele ebhethri angaphezulu kakhulu kunemodi yamanje engaguquki. 6 Umjikelezo ohlukile womsebenzi we-pulse uthinta ukushajwa kwe-pulse Isikhathi sokuphuma esinegethivu samanje sihamba kancane, kuba nomphumela othile, futhi uma siba side isikhathi sokuphuma, ukushaja okunensayo; lapho iflethi elifanayo, iyunithi iyashajwa, isikhathi sokukhipha siba side. Njengoba kubonakala kuthebula elingezansi, umjikelezo wemisebenzi owehlukene uyasebenza futhi owamukelwe kugesi unomthelela ocacile, kodwa umehluko wezinombolo awumkhulu kakhulu.

Futhi lokhu okuhlobene, kunemingcele emibili ebalulekile, isikhathi sokushaja nezinga lokushisa akuboniswa. Ngakho-ke, ukukhethwa kokushaja kwe-pulse kuphakeme kunokushaja kwamanje okuqhubekayo okuqhubekayo, kanye nokukhetha okukhethekile komjikelezo womsebenzi, kufanele ugxile ekukhuphukeni kwezinga lokushisa kanye nesidingo sesikhathi sokushaja.
