Check and solution for battery failure

Umbhali :Iflowpower-UMboneleli weSikhululo saMandla esiphathwayo

Okokuqala, ungakwazi ukudibanisa yomtya bamthethela ukuya yomtya zitshajwe, kwaye itshaja kufuneka itshintshwe ngokukhawuleza. Ibhetri owomileyo kufuneka zongezwe amanzi acocekileyo okanye 1,050 sulphuric acid ukugcina ezibiza, kunye namandla ibhetri incamatheliswe.

Ukuba kufumaniseke ukuba akukho sulfate Ngokufanayo, umthamo kufuneka ibuyiselwe. Okwesibini, izityholo yesondlo ibhetri owomileyo emva ukongeza ukuyibiza engamanzi kufuneka ilawulwe: i 1.8a eliphezulu ngoku ilawulwa, abizwa i-iiyure 10-15, iqela ngalinye (3, 4) Le ezibiza ombane ze battery lilawulwa 14 .

7V / kuphela okanye Yiba ngaphezulu. Ukwehluka ibhetri ibhetri deformation kungenxa gqolo inani iibhetri, kwaye amanzi ngaphantsi, kwaye ibonakala nebhetri: 1. Umthamo ubushushu lifinyele, indawo yokugcina iphezulu ubushushu amanzi sikhulu, ilahleko yamanzi, ibhetri umthamo ubushushu eliphantsi kakhulu, kwaye kukho kokuhluma ubushushu ukuze ukuzila ubushushu ibhetri okukhawulezayo; 2.

Isiteshi oxygen uba ezigudileyo, ioksijini ukuba ibonakala kwi electrode elungileyo kulula ukufikelela electrode elibi ngomzila; 3. Ibhetri adhesion ukuya nembasa ezintle nezimbi ke saxabana, kwa oku komelela kunye lwangaphakathi siyandiswa, kwaye ubushushu kwanda ngexesha intlawulo kunye nokukhutshwa inkqubo. Iqondo lobushushu eli ngokukhawuleza kakhulu, kusekwe isangqa engathethekiyo, oko kukuthi, i-ebizwa ngokuba waphuma thermal yolawulo, lobushushu lokugqibela kufika kumgomo we 80, nto leyo deformation le istili engaphandle.

Itshekhi nandzu kunye nokuchongwa: iseti iibhetri Ukuba ngaxeshanye gqitha, cinga ingxaki kokutshintsha kwitshaja. Inye kuphela okanye 2 kuhlenga-iseti iibhetri, kukho ithuba ezi iziphene: 1. Intlawulo Ibhetri awungqinelani, yaye ezinye kwentengo ibhetri ebangela deformation xa ugcwalisa.

Kusenokwenzeka ukuba short circuit kwezinye iimeko self-ekubhobhozeni-single wanika, okanye. 2. Battery Xa kwipleyiti polar na sulfate vuhlayiseki, kwa oku komelela kunye lwangaphakathi siyandiswa, kwaye nobushushu ehlaselayo deformation.

3. Battery Xa uqhagamshela, basabela sibangelwa ukuba shushu isizukulwana deformation. 4.

Ibhetri akuthethi nizalise kongezwe electrolyte ukuze yokunqongophala nkqubo, yaye ekugqibeleni kokukhanya okuluhlaza Ayibuyanga kwi ngenxa akuba, ebangela deformation. Solition nokuqhubela lweempazamo eziziisekondari: 1. Ngenxa yokuqinisekisa ulwelo unlilled, yongeza ulwelo kakhulu kangangoko kunokwenzeka ukwandisa okanye alinde xa kukuvela ufudumele.

2. Saziso isekethe yangaphakathi elifutshane okanye isiphaluka emfutshane micro, kwaye umkhwa ukuba badla. 3.

Ngexesha ukusetyenziswa, zama ukwenza ngokugqithiseleyo lubandakanywe nezenzo obhobhozayo ngokugqithiseleyo, uze ugcine yokugcina yakho ibhetri. 4. Talkually khangela kwitshaja, kufuneka kubekho izinto akukho zitshajwe ngakumbi.

Ukuba zibiza kwiqondo lobushushu eliphezulu, qiniseka ukuba ukuqinisekisa ukuba ibhetri dissolutely dissipated. Ukuza kuthi ga ngoku, kuyimfuneko ukuba indlela amanyathelo okupholisa okanye ukunqumlela ixesha Ukuvuya womserbia. Kungenjalo, ayeke ukutshaja.

Umqulu ibhetri esingangqinelaniyo ukusingatha intsalela imiqulwana ibhetri ingxaki ehlabathini ebomini. protocol yawo ezahlukeneyo. Uhlolo isisombululo iziphene 1.

Okokuqala usebenzisa ibhetri isigxina ngokupheleleyo, ngoko ndiyenza ezinereyithi iyure 2. Ngexesha lenkqubo obhobhozayo, lo lombane ibhetri kulinganiswa rhoqo, kwaye ibhetri umva yokumpompoza amandla ezikhethiweyo ukuba isonjululwe. 2.

Okokuqala yingozi sulfate 1,050 yaze yangxenga ifuthe lomanyano ukuze ubone nje ukuba kukho electrolyte flow, uze gqolo imali iiyure 12-15. Nika ingqalelo iqondo lobushushu battery mayingagqithi 50 ¡ã C ngexesha ukutshaja.

Emva kokuba abize liphelile, ume iiyure 0.5-4, kwakhona ukusetyenziswa-izinga 2 iyure nokukhutshwa. Ngexesha lenkqubo obhobhozayo, ixabiso ombane enye kulinganiswa.

Ukuba ixesha obhobhozayo alifikeleli umgangatho, okanye kukho umahluko ubuninzi phakathi kwexesha ukubhobhoza mde lonke ibhetri, umsebenzi isigxina kunye nenkqubo ukubhobhoza nayo iyafuneka ukuze zihambelane neemfuno. kude. Ukuba kuphindwe kwaye nomjikelo ukubhobhoza, amandla ibhetri akukho isibhengezo okanye ndashiyeka 0V kunye noxinzelelo ekunene ephantsi.

Le bhetri iqhelekile ukuba yi-short-circuited okanye imathiriyeli esebenzayo yohlulwe kanobom, i-sulfate engenakujikwa, njl. njl., ayinakulungiswa, kufuneka ichithwe. Kuba iibhetri ezihlangabezana neemfuno, kufuneka iphelelwe phantsi kwamandla ombane rhoqo 15V / iimeko intlawulo kuphela, kunye electrolyte equkuqelayo, zosula umphezulu ibhetri, ivalve hood, incamathelisa kunye PVC okanye chloroform adhesive Fit.

Enye into kubomi bebhetri kukubunjwa kweekhemikhali. Wonke umntu uvile ngeebhetri ze-lithium-ion, okanye iibhetri ze-lithium polymer, kodwa esi sigama sisasazeke kakhulu - njengokuchaneka okufanayo kwe-injini yomlilo yangaphakathi. Ngaba uthetha ngeenjini zepetroli okanye iinjini zedizili, okanye injini yegesi yendalo? Iiyoni zelithium (en.

wikipedia.org/wiki/lithium-ion_battery) ibhekisa kwibhetri esebenzisa i-lithium ion ukuhambisa iindleko. Oku kubandakanya ukwakheka kwekhemistri yebhetri yokwenyani uluhlu olubanzi kakhulu.

I-Lithium polymer (en.wikipedia.org/wiki/lithium_polymer_battery) okanye i-LIPO, ithetha kuphela iyunithi yokupakisha ibhetri enezithako zekhemikhali ze-lithium ion.

Eyona nto ibaluleke kakhulu yinto yokwenene yekhemikhali eyasabela kwibhetri. Ngokuqhelekileyo ibandakanyeka kwezi: i-lithium cobaltate (i-LiCoO2, i-ICR) i-lithium manganate (i-LiMn2O4, i-IMR) i-nickel-cobalt aluminium (i-liniMNCO2, i-NCA) i-Nickel manganese cobalt (liFePO4, LFP) i-lithium titanate (LTO) ) Okanye ube nolunye uhlobo lwale nto. . Emva koko, ukwakhiwa kweekhemikhali zebhetri, kukho ezinye izinto ezinempembelelo enkulu kumandla, amandla, kunye nexesha lokuphila.

Iinkcukacha ze-anode kunye nokwakhiwa kwe-cathode / ulwakhiwo, imixube ethile, kunye nezongezo (ezichaphazela kakhulu ukusebenza kwebhetri) ziyahluka kubavelisi abahlukeneyo, naphakathi kweemveliso zebhetri ezahlukeneyo zomenzi omnye. Ngelishwa, uninzi lwezi nkcukacha azifumaneki nje kwi-Intanethi. Ngokufanelekileyo, sinethemba lokuba ibhetri inoxinano lwamandla aphezulu e-ultraever x (amandla angaphezulu kwiyunithi yobunzima bobunzima okanye ugcino lwevolumu), ukuxinana kwamandla e-ultraruff X (amandla anokukhutshwa ngexesha leyunithi), kunye nobomi bomjikelezo obungenamkhawulo (bunokusetyenziswa. Abazange babe nayo nayiphi na ilahleko yamandla de kwaba sekupheleni kwendalo.

Kakade ke, kuloo ndalo iphela, i-unicorn iya kukhupha kwakhona i-ayisikrimu ye-rainbow (www.youtube.com/watch?v =ybywhdlo43q) ilishwa kakhulu, asihlali kwi-Utopian universe.

Asilandeli i-physics, umthetho weekhemikhali, kwindalo yethu yonke, ngokuqhelekileyo: unokuba nokunye oku, kodwa kwelinye icala, ngaphantsi. Ukuba ufuna intlanzi kunye nebhere, iindleko ziya kufa. Ke, asikho ngexesha, kukho into enkulu ekukhetheni iimoto zombane.

Akukho mntu uya kuchitha isigidi seedola zaseMelika ukuthenga imoto yombane kwiNissan Ukumamela umoya, nokuba ibhetri inekhemikhali. Ke ngoko, siyaqhubeka nokukhetha eyona, imveliso yeekhemikhali efikelelekayo.
