Uluhlu olubanzi losetyenziso lweebhetri

Injongo yokuphuhlisa itekhnoloji ephezulu kukuyenza isebenze ngcono uluntu. Ukususela ekuqalisweni kwayo kwi-1990, iibhetri ze-lithium-ion ziye zanda ngenxa yokusebenza kwazo kakuhle kwaye zisetyenziswe ngokubanzi kuluntu. Iibhetri zeLithium-ion ngokukhawuleza zahlala amasimi amaninzi kunye neenzuzo ezingenakuthelekiswa nezinye iibhetri, ezifana neefowuni eziphathwayo ezaziwayo, iikhompyutheni zekhompyutheni, iikhamera zevidiyo ezincinci, njl. Amazwe amaninzi asebenzisa le bhetri kwiinjongo zomkhosi. Isicelo sibonisa ukuba ibhetri ye-lithium-ion ngumthombo wamandla amancinci aluhlaza.

Isine, uhlobo lwebhetri ye-lithium kunye nokukhethwa kwamandla

Okokuqala, bala umbane oqhubekayo ofunekayo ibhetri ukubonelela ngokusekelwe kumandla emoto yakho (ifuna amandla okwenene, kwaye ngokubanzi, isantya sokukhwela sihambelana namandla okwenene ahambelanayo). Umzekelo, masithi i-injini inomjelo oqhubekayo we-20a (1000w motor kwi-48v). Kwimeko apho, ibhetri idinga ukubonelela nge-20a yangoku ixesha elide. Ukunyuka kwamaqondo obushushu akunzulu (nokuba iqondo lobushushu lingama 35 degrees ngaphandle ehlotyeni, ubushushu bebhetri bulawulwa ngcono ngaphantsi kwe 50 degrees). Ukongezelela, ukuba i-20a yangoku kwi-48v, i-overpressure iphindwe kabini (96v, njenge-CPU 3), kwaye ngoku okuqhubekayo kuya kufikelela malunga ne-50a. Ukuba uthanda ukusebenzisa i-over-voltage ixesha elide, nceda ukhethe ibhetri enokuthi ibonelele ngokuqhubekayo i-50a yangoku (usenake ingqalelo ekunyukeni kweqondo lokushisa). Uqhubekeko lwangoku lwesiphango apha ayingomthamo webhetri wokukhupha umrhwebi. Umrhwebi ubanga ukuba i-C embalwa (okanye amakhulu e-amperes) ngumthamo wokukhupha ibhetri, kwaye ukuba ikhutshwe ngoku, ibhetri iya kuvelisa ukushisa okukhulu. Ukuba ubushushu abuchithwanga ngokwaneleyo, ubomi bebhetri buya kuba bufutshane. (Kwaye indawo yebhetri yezithuthi zethu zombane kukuba iibhetri zixutywe kwaye zikhutshwe. Ngokwenene, akukho zithuba zishiywe, kwaye ukupakishwa kuqiniswe kakhulu, kungabikho indlela yokunyanzela ukupholisa umoya ukukhupha ukushisa). Indawo esiyisebenzisayo inzima kakhulu. Ukukhutshwa kwebhetri okwangoku kufuneka kuncitshiswe ukuze kusetyenziswe. Ukuvavanya amandla angoku okukhutshwa kwebhetri kukubona ukuba ibhetri ingakanani iqondo lobushushu elihambelana nalo ngoku.

Umgaqo kuphela oxutyushwa apha kukunyuka kweqondo lokushisa kwebhetri ngexesha lokusetyenziswa (ubushushu obuphezulu butshaba olubulalayo lwebhetri ye-lithium). Kungcono ukulawula ukushisa kwebhetri ngaphantsi kwe-50 degrees. (Phakathi kwe-20-30 degrees iyona nto ingcono). Oku kuthetha ukuba ukuba luhlobo lwebhetri ye-lithium (ekhutshwe ngaphantsi kwe-0.5C), ukukhutshwa ngokuqhubekayo kwe-20a kufuna umthamo ongaphezulu kwe-40ah (ngokuqinisekileyo, eyona nto ibalulekileyo ixhomekeke kwi-internal resistance yebhetri). Ukuba ibhetri ye-lithium yohlobo lwamandla, kuyinto yesiko ukukhupha ngokuqhubekayo ngokwe-1C. Nkqu A123 ultra-low yangaphakathi ukumelana amandla uhlobo lithium ibhetri idla ngokufanelekileyo ukususa kwi-1C (akukho ngaphezu kwe-2C ingcono, ukukhutshwa kwe-2C kungasetyenziselwa kuphela isiqingatha seyure, kwaye akuncedi kakhulu). Ukukhethwa komthamo kuxhomekeke kubukhulu bendawo yokugcina imoto, ibhajethi yenkcitho yomntu, kunye noluhlu olulindelekileyo lwemisebenzi yemoto. (Isakhono esincinci ngokubanzi sifuna ibhetri ye-lithium yamandla)

5. Ukuhlolwa kunye nokuhlanganiswa kweebhetri

I-taboo enkulu yokusebenzisa iibhetri ze-lithium kuthotho kukungalingani okuqatha kokuzikhupha kwebhetri. Logama wonke umntu engalingani ngokulinganayo, kulungile. Ingxaki kukuba le meko ingazinzanga ngequbuliso. Ibhetri elungileyo ine-self-discharge encinci, isivunguvungu esibi sinokuzikhupha okukhulu, kwaye imeko apho ukuzikhupha kuncinci okanye ngokuqhelekileyo kutshintshile ukusuka kokulungileyo ukuya kubi. Xela, le nkqubo ayizinzanga. Ngoko ke, kuyimfuneko ukukhupha iibhetri ngokuzikhupha okukhulu kwaye ushiye ibhetri kuphela ngokuzikhupha okuncinci (ngokubanzi, ukuzikhupha kweemveliso ezifanelekileyo kuncinci, kwaye umenzi uyilinganise, kwaye ingxaki kukuba. iimveliso ezininzi ezingafanelekanga zingena emarikeni).

Ngokusekelwe kwi-self-discharge encinci, khetha uchungechunge olunomthamo ofanayo. Nangona amandla awafani, akayi kuchaphazela ubomi bebhetri, kodwa iya kuchaphazela amandla okusebenza kwepakethi yebhetri yonke. Ngokomzekelo, iibhetri ze-15 zinomthamo we-20ah, kwaye ibhetri enye kuphela yi-18ah, ngoko ke umthamo opheleleyo weli qela leebhetri unokuba ngu-18ah kuphela. Ekupheleni kokusetyenziswa, ibhetri iya kufa, kwaye ibhodi yokukhusela iya kukhuselwa. I-voltage yebhetri yonke isephezulu kakhulu (kuba i-voltage yezinye iibhetri ze-15 isemgangathweni, kwaye kusekho umbane). Ke ngoko, amandla ombane okhuselo lokukhutshwa kwepakethi yebhetri iyonke anokwazi ukuba umthamo wepakethi yebhetri yonke uyafana (ngaphandle kokuba iseli yebhetri nganye kufuneka igcwaliswe ngokupheleleyo xa yonke ipakethi yebhetri itshajwe ngokupheleleyo). Ngamafutshane, umthamo ongalinganiyo awuchaphazeli ubomi bebhetri kodwa uchaphazela kuphela isakhono seqela lonke, ngoko zama ukukhetha indibano enedigri efanayo.

Ibhetri edibeneyo kufuneka ifezekise ukuchasana koqhagamshelwano lwe-ohmic phakathi kwee-electrode. Okuncinci ukuchasana koqhagamshelwano phakathi kocingo kunye ne-electrode, kungcono; ngaphandle koko, i-electrode enokumelana okubalulekileyo koqhagamshelwano iya kutshisa. Obu bushushu buya kudluliselwa ngaphakathi kwibhetri kunye ne-electrode kwaye buchaphazele ubomi bebhetri. Ngokuqinisekileyo, ukubonakaliswa kokumelana okukhulu kwendibano kukuhla kwamandla ombane okubalulekileyo kwipakethi yebhetri phantsi kokukhutshwa okufanayo kwangoku. (Inxalenye yokuhla kwamandla ombane kukuxhathisa kwangaphakathi kweseli, kwaye inxalenye kukuxhathisa okudityanisiweyo kunye nokumelana nocingo)

Isithandathu, ukukhethwa kwebhodi yokukhusela kunye nokutshaja kunye nokukhupha imiba yokusetyenziswa

(Idatha yeye lithium iron phosphate ibhetri, umgaqo webhetri ye-3.7v eqhelekileyo iyafana, kodwa ulwazi lwahlukile)

Injongo yebhodi yokukhusela kukukhusela ibhetri ekugqithiseni kunye nokukhutshwa ngokugqithiseleyo, ukukhusela umbane ophezulu ekonakalisweni kwesiphango kunye nokulinganisa umbane webhetri xa ibhetri ihlawuliswe ngokupheleleyo (ubuchule bokulinganisa ngokuqhelekileyo buncinci, ngoko ke ukuba kukho ibhodi yokukhusela ibhetri yokuzikhupha, iyingqayizivele Kungumngeni ukulinganisela, kwaye kukho neebhodi zokukhusela ezilungelelanisayo nakweyiphi na imeko, oko kukuthi, imbuyekezo yenziwa ukususela ekuqaleni kokutshaja, okubonakala kunqabile kakhulu).

Kubomi bepakethi yebhetri, kucetyiswa ukuba i-voltage yokutshaja ibhetri ingadluli kwi-3.6v nangaliphi na ixesha, oku kuthetha ukuba i-voltage yesenzo sokukhusela ibhodi yokukhusela ayikho ngaphezu kwe-3.6v, kwaye i-voltage elinganisiweyo iyacetyiswa ukuba ibe I-3.4v-3.5v (iseli nganye i-3.4v ihlawuliswe ngaphezu kwe-99% Ibhetri, ibhekisela kwi-static state, i-voltage iya kwanda xa ihlawulisa ngokuphezulu kwangoku). I-voltage yokukhusela ukukhutshwa kwebhetri ingaphezulu kwe-2.5v (ngaphezulu kwe-2v akuyona ingxaki enkulu, ngokuqhelekileyo kukho ithuba elincinci lokuyisebenzisa ngokupheleleyo ngaphandle kwamandla, ngoko ke le mfuneko ayiphezulu).

I-voltage ephezulu ephakanyisiweyo yeshaja (isinyathelo sokugqibela sokutshaja sinokuba yimowudi ephezulu yokutshaja i-voltage rhoqo) ngu-3.5 *, inani leentambo, ezifana ne-56v kwimigqa ye-16. Ngesiqhelo, ukutshaja kunokunqunyulwa kumndilili we-3.4v ngeseli nganye (ichajiwe ngokupheleleyo) ukuqinisekisa ubomi bebhetri. Sekunjalo, ngenxa yokuba ibhodi yokukhusela ingakaqalisi ukulinganisela ukuba i-core yebhetri ine-self-discharge enkulu, iya kuziphatha njengeqela lonke ngexesha; umthamo uyancipha ngokuthe ngcembe. Ke ngoko, kuyafuneka ukuba ubize rhoqo ibhetri nganye ukuya kwi-3.5v-3.6v (efana neveki nganye) kwaye uyigcine iiyure ezimbalwa (ukuba nje umndilili mkhulu kune-equalization yokuqalisa umbane), kokukhona uzikhupha. , ixesha elide ukulingana kuya kuthatha. I-self-discharge Iibhetri ezigqithisiweyo zinzima ukulinganisa kwaye zifuna ukupheliswa. Ngoko xa ukhetha ibhodi yokukhusela, zama ukukhetha ukhuseleko lwe-3.6v overvoltage kwaye uqale ukulinganisa malunga ne-3.5v. (Uninzi lwe-overvoltage yokukhusela kwimarike ingaphezulu kwe-3.8v, kwaye i-equilibrium yenziwe ngaphezu kwe-3.6v). Ukukhetha i-voltage elinganayo yokuqalisa i-balanced ibaluleke kakhulu kune-voltage yokukhusela ngenxa yokuba amandla ombane aphezulu anokulungelelaniswa ngokulungelelanisa umda we-voltage ephezulu yeshaja (oko kukuthi, ibhodi yokukhusela ayinalo ithuba lokukhusela i-voltage ephezulu). Sekunjalo, masithi i-voltage elinganayo iphezulu. Kwimeko apho, ipakethe yebhetri ayinalo ithuba lokulinganisa (ngaphandle kokuba i-voltage yokutshaja inkulu kune-voltage equilibrium, kodwa oku kuchaphazela ubomi bebhetri), iseli iya kuncipha ngokuthe ngcembe ngenxa yomthamo wokuzikhupha (iseli efanelekileyo ene- ukuzikhupha kwe-0 akukho).

Ukukhupha ngokuqhubekayo amandla akhoyo ebhodi yokukhusela. Le yeyona nto imbi kakhulu yokuphawula. Ngenxa yokuba amandla akhoyo okunciphisa ibhodi yokukhusela ayinantsingiselo. Umzekelo, ukuba uvumela ityhubhu ye-75nf75 iqhubeke idlula i-50a yangoku (ngeli xesha, amandla okufudumeza amalunga ne-30w, ubuncinane i-60w emibini ngokulandelelana kunye nebhodi ye-port efanayo), nje ukuba kukho ubushushu bokushisa ngokwaneleyo ukuba buchithe. ubushushu, akukho ngxaki. Inokugcinwa kwi-50a okanye nangaphezulu ngaphandle kokutshisa ityhubhu. Kodwa awukwazi ukuthetha ukuba le bhodi yokukhusela inokuhlala i-50a yangoku kuba uninzi lweepaneli zokukhusela zomntu wonke zifakwe kwibhokisi yebhetri kufuphi kakhulu nebhetri okanye ivale. Ngoko ke, ukushisa okuphezulu okunjalo kuya kutshisa ibhetri kwaye kushushu. Ingxaki kukuba ubushushu obuphezulu lutshaba olubulalayo lwesiphango.

Ngoko ke, indawo yokusetyenziswa kwebhodi yokukhusela inquma indlela yokukhetha umda wangoku (kungekhona umthamo wangoku webhodi yokukhusela ngokwayo). Masithi ibhodi yokukhusela ikhutshwe kwibhokisi yebhetri. Kwimeko apho, phantse nayiphi na ibhodi yokukhusela ene-heat sink inokusingatha i-current eqhubekayo ye-50a okanye nangaphezulu (ngeli xesha, kuphela amandla ebhodi yokukhusela aqwalaselwa, kwaye akukho mfuneko yokukhathazeka malunga nokunyuka kweqondo lokushisa okubangela umonakalo iseli yebhetri). Emva koko, umbhali uthetha ngendawo ehlala isetyenziswa ngumntu wonke, kwindawo enye evalelweyo njengebhetri. Ngeli xesha, amandla aphezulu okufudumeza kwebhodi yokukhusela alawulwa kakuhle ngaphantsi kwe-10w (ukuba ibhodi yokukhusela encinci, idinga i-5w okanye ngaphantsi, kwaye ibhodi yokukhusela ivolumu enkulu ingaba ngaphezu kwe-10w kuba inokutshatyalaliswa kokushisa okulungileyo. kwaye iqondo lobushushu aliyi kuba phezulu kakhulu). Ngokumalunga nokuba kungakanani okufanelekileyo, kuyacetyiswa ukuba uqhubeke. Ukushisa okuphezulu kwebhodi yonke akudluli kwii-degrees ezingama-60 xa kusetyenziswa ngoku (ii-50 degrees zingcono). Ngokwethiyori, iqondo lokushisa eliphantsi lebhodi yokukhusela, lingcono, kwaye lingaphantsi liya kuchaphazela iiseli.

Ngenxa yokuba ibhodi ye-port efanayo idibaniswe kwi-series kunye ne-mos yokutshaja yombane, ukuveliswa kobushushu bemeko efanayo kuphindwe kabini kwibhodi yebhodi eyahlukileyo. Kwisizukulwana esifanayo sokushisa, kuphela inani leetyhubhu liphindwe kane (phantsi kwesiseko semodeli efanayo ye-mos). Masibale, ukuba i-50a eqhubekayo yangoku, ngoko ukuchasana kwangaphakathi kwe-mos yi-milliohms ezimbini (ii-5 75nf75 iityhubhu ezifunekayo ukuze ufumane oku kufana nokuchasana kwangaphakathi), kwaye amandla okufudumala yi-50 * 50 * 0.002 = 5w. Ngeli xesha, kunokwenzeka (enyanisweni, umthamo wangoku we-2 milliohms ukuchasana kwangaphakathi ungaphezulu kwe-100a, akukho ngxaki, kodwa ubushushu bukhulu). Ukuba ibhodi efanayo yezibuko, i-4 2 milliohm yangaphakathi yokumelana mos iyafuneka (nganye ukuchasana kwangaphakathi ezimbini ezihambelanayo yi-miliohm enye, kwaye emva koko idityaniswe kuthotho, ukuchasana okupheleleyo kwangaphakathi kuyalingana ne-2 yezigidi ze-75 iityhubhu ezisetyenziswayo, inani lilonke 20). Masithi i-100a eqhubekayo yangoku ivumela amandla okufudumala ukuba abe yi-10w. Kwimeko apho, umgca kunye nokumelana kwangaphakathi kwe-1 milliohm kuyadingeka (ngokuqinisekileyo, ukuchasana kwangaphakathi okulinganayo okulinganayo kunokufumaneka ngoxhumo oluhambelanayo lwe-MOS). Ukuba inani lamazibuko ahlukeneyo lisaphindwe kane, ukuba i-100a eqhubekayo yangoku isavumela amandla aphezulu okufudumeza 5w, ke ityhubhu ye-0.5 milliohm kuphela ingasetyenziswa, efuna ngokuphindwe kane inani le-mos xa kuthelekiswa ne-50a eqhubekayo ngoku ukuvelisa okufanayo. umthamo wobushushu). Ngoko ke, xa usebenzisa ibhodi yokukhusela, khetha ibhodi enokuchasana nokungakhathali kwangaphakathi ukunciphisa ubushushu. Ukuba ukuchasana kwangaphakathi kuye kwagqitywa, nceda uvumele ibhodi kunye nobushushu bangaphandle buchithe ngcono. Khetha ibhodi yokukhusela kwaye ungamameli umthamo wangoku oqhubekayo womthengisi. Mane ubuze ukuchasana kwangaphakathi okupheleleyo kwesekethe yokukhutshwa kwebhodi yokukhusela kwaye uyibale ngokwakho (buza ukuba luhlobo luni lwetyhubhu esetyenzisiweyo, ubungakanani bobungakanani obusetyenzisiweyo, kwaye uhlolisise ukubala kwangaphakathi ukuchasana ngokwakho). Umbhali uvakalelwa kukuba ukuba ikhutshwe phantsi kwesigxina esiqhubekayo somthengisi, ukunyuka kweqondo lokushisa kwebhodi yokukhusela kufuneka kube phezulu. Ngoko ke, kungcono ukhethe ibhodi yokukhusela ene-derating. (Yithi i-50a eqhubekayo, ungasebenzisa i-30a, ufuna i-50a rhoqo, kungcono ukuthenga i-80a eqhubekayo). Kubasebenzisi abasebenzisa i-CPU ye-48v, kucetyiswa ukuba ukuchasana kwangaphakathi kwebhodi yokukhusela akukho ngaphezu kweemiliyoni ezimbini.

Umahluko phakathi kwebhodi yezibuko enye kunye nebhodi yezibuko eyahlukileyo: ibhodi yezibuko efanayo ngumgca ofanayo wokutshaja kunye nokukhupha, kwaye zombini ukutshaja kunye nokukhupha kukhuselwe.

Ibhodi yezibuko eyahlukileyo izimeleyo kwimigca yokutshaja kunye nokukhupha. I-port yokutshaja ikhusela kuphela kwi-overcharge xa ​​itshaja kwaye ayikhuseli ukuba isusiwe kwi-port yokutshaja (kodwa inokukhupha ngokupheleleyo, kodwa umthamo wangoku we-port yokutshaja uncinci kakhulu). I-port yokukhupha ikhusela ukukhutshwa ngokugqithisileyo ngexesha lokukhutshwa. Ukuba ukutshaja kwizibuko lokukhupha, intlawulo engaphezulu ayigqunywanga (ngoko ke ukutshajiswa okubuyela umva kwe-CPU kusetyenziswa ngokupheleleyo kwibhodi yezibuko eyahlukileyo. Kwaye intlawulo ebuyela umva incinci ngaphezu kwamandla asetyenzisiweyo, ngoko Sukuba nexhala malunga nokutshaja kakhulu Ibhetri ngenxa yokutshaja umva Ngaphandle kokuba uphuma nentlawulo epheleleyo, ziikhilomitha ezimbalwa ezantsi kwangoko. ukusuka kwindawo yokukhupha, ngaphandle kokuba uhlala ubeka iliso kwi-voltage yokutshaja (njengokutshaja okwexeshana ecaleni kwendlela kaxakeka ephezulu yangoku, unokuthembela kwizibuko lokukhupha, kwaye uqhubeke nokukhwela ngaphandle kokuhlawuliswa ngokupheleleyo, ungakhathazeki malunga nokutshaja kakhulu)

Bala ubuninzi obuqhubekayo bangoku bemoto yakho, khetha ibhetri enomthamo ofanelekileyo okanye amandla anokuthi ahlangabezane nale mihla yangoku, kunye nokunyuka kobushushu kulawulwa. Ukuchasana kwangaphakathi kwebhodi yokukhusela kuncinci kunokwenzeka. Ukhuseleko lwangoku lwebhodi yokukhusela lufuna kuphela ukhuseleko lweesekethe ezimfutshane kunye nolunye ukhuseleko lokusetyenziswa okungaqhelekanga (ungazami ukukhawulela okwangoku okufunwa ngumlawuli okanye i-motor ngokunciphisa idrafti yebhodi yokukhusela). Kuba ukuba injini yakho idinga i-50a yangoku, awusebenzisi ibhodi yokukhusela ukumisela i-40a yangoku, eya kubangela ukukhuselwa rhoqo. Ukungaphumeleli kwamandla ngokukhawuleza komlawuli kuya kulimaza ngokulula umlawuli.

Isixhenxe, uhlalutyo olusemgangathweni lwevoltage yeebhetri ze-lithium-ion

(1) Ivolthi yesekethe evulekileyo: ibhekisa kumbane webhetri ye-lithium-ion kwimeko engasebenziyo. Ngeli xesha, akukho kuhamba ngoku. Xa ibhetri ihlawuliswe ngokupheleleyo, umahluko onokuthi ubekho phakathi kwe-electrode echanekileyo kunye ne-negative yebhetri idla ngokumalunga ne-3.7V, kwaye ephakamileyo inokufikelela kwi-3.8V;

(2) Ngokuhambelana nombane ovulekileyo wesiphaluka ngumbane osebenzayo, oko kukuthi, i-voltage yebhetri ye-lithium-ion kwimeko esebenzayo. Ngeli xesha, kukho ukuhamba ngoku. Ngenxa yokuba ukuchasana kwangaphakathi xa ukuhamba kwangoku kuya kunqotshwa, i-voltage yokusebenza ihlala iphantsi kunomthamo opheleleyo ngexesha lombane;

3 ukukhutshwa kuphelile malunga ne-2.95V;

4 Umbane olinganisiweyo webhetri ye-lithium-ion yi-3.7V. Ingabonwa ukuba i-voltage esemgangathweni ngumbane osebenzayo oMgangatho;

Ukujonga kwi-voltage yeebhetri ezine ze-lithium-ion ezikhankanywe ngasentla, i-voltage yebhetri ye-lithium-ion ebandakanyekayo kwimeko yokusebenza ine-voltage eqhelekileyo kunye ne-voltage yokusebenza. Kwimeko engasebenziyo, i-voltage yebhetri ye-lithium-ion iphakathi kombane ovulekileyo wesiphaluka kunye nokuphela kombane ngenxa yebhetri ye-lithium-ion. Ukusabela kweekhemikhali kwebhetri ye-ion kunokusetyenziswa ngokuphindaphindiweyo. Ngoko ke, xa i-voltage yebhetri ye-lithium-ion ikwi-voltage yokuphelisa, ibhetri kufuneka ihlawulwe. Ukuba ibhetri ayihlawuliswanga ixesha elide, ubomi bebhetri buya kucuthwa okanye icinywe.
