Njengomthombo oyintloko wamandla ezithuthi ezintsha zamandla, iibhetri zamandla zibaluleke kakhulu kwizithuthi ezintsha zamandla. Ngexesha lokusetyenziswa kwesithuthi, ibhetri iya kujongana neemeko zokusebenza ezinzima nezitshintshayo. Ukuze kuphuculwe uluhlu lokuhamba ngenqanawa, isithuthi kufuneka silungiselele iibhetri ezininzi kangangoko kwindawo ethile, ngoko ke indawo yebhetri kwisithuthi incinci kakhulu. Ibhetri ivelisa ubushushu obuninzi ngexesha lokusebenza kwesithuthi kwaye iqokelelana kwindawo encinci ngokuhamba kwexesha. Ngenxa yoxinano lweeseli kwibhetri, kunzima ngakumbi ukukhupha ubushushu kwindawo ephakathi ukuya kwinqanaba elithile, nto leyo eya kwandisa ukungangqinelani kobushushu phakathi kweeseli, nto leyo eya kunciphisa ukusebenza kakuhle kokutshaja nokukhupha ibhetri kwaye ichaphazele amandla ebhetri; Iya kubangela ukubaleka kobushushu kwaye ichaphazele ukhuseleko kunye nobomi benkqubo.
Ubushushu bebhetri yamandla bunempembelelo enkulu ekusebenzeni kwayo, ubomi kunye nokhuseleko. Kubushushu obuphantsi, ukumelana kwangaphakathi kweebhetri ze-lithium-ion kuya kwanda kwaye amandla aya kuncipha. Kwiimeko ezigqithisileyo, i-electrolyte iya kubanda kwaye ibhetri ayinakukhutshwa. Ukusebenza kobushushu obuphantsi kwenkqubo yebhetri kuya kuchaphazeleka kakhulu, okubangela ukusebenza kombane wezithuthi zombane. Ukuncipha kobushushu kunye nobubanzi. Xa utshaja izithuthi zamandla amatsha phantsi kweemeko zobushushu obuphantsi, i-BMS eqhelekileyo iqala ifudumeze ibhetri kubushushu obufanelekileyo ngaphambi kokuba itshaje. Ukuba ayiphathwanga kakuhle, iya kukhokelela ekutshajisweni kombane ngoko nangoko, okubangela ukujikeleza okufutshane kwangaphakathi, kwaye umsi omninzi, umlilo okanye ukuqhuma kunokwenzeka. Ingxaki yokhuseleko lokutshaja kobushushu obuphantsi kwenkqubo yebhetri yezithuthi zombane ithintela ukukhuthazwa kwezithuthi zombane kwiindawo ezibandayo kakhulu.
Ulawulo lobushushu bebhetri ngomnye wemisebenzi ebalulekileyo kwi-BMS, ikakhulu ukugcina iphakheji yebhetri isebenza kuluhlu lobushushu olufanelekileyo ngamaxesha onke, ukuze kugcinwe imeko yokusebenza engcono kakhulu yephakheji yebhetri. Ulawulo lobushushu bebhetri luquka ikakhulu imisebenzi yokupholisa, ukufudumeza kunye nokulinganisa ubushushu. Imisebenzi yokupholisa kunye nokufudumeza ihlengahlengiswa kakhulu ngokwempembelelo enokubakho yobushushu obungaphandle kwibhetri. Ukulinganiswa kobushushu kusetyenziselwa ukunciphisa umahluko wobushushu ngaphakathi kwephakheji yebhetri kunye nokuthintela ukubola ngokukhawuleza okubangelwa kukushisa kakhulu kwenxalenye ethile yebhetri.
Ngokubanzi, iindlela zokupholisa iibhetri zamandla zahlulwe kakhulu zibe ziindidi ezintathu: ukupholisa umoya, ukupholisa ulwelo kunye nokupholisa ngokuthe ngqo. Indlela yokupholisa umoya isebenzisa umoya wendalo okanye umoya opholileyo kwigumbi labakhweli ukuze udlule kumphezulu webhetri ukuze kufezekiswe ukutshintshiselana kobushushu kunye nokupholisa. Ukupholisa ulwelo ngokubanzi kusebenzisa umbhobho ozimeleyo wokupholisa ukufudumeza okanye ukupholisa ibhetri yamandla. Okwangoku, le ndlela yeyona iphambili yokupholisa. Umzekelo, iTesla kunye neVolt zombini zisebenzisa le ndlela yokupholisa. Inkqubo yokupholisa ngokuthe ngqo isusa umbhobho wokupholisa webhetri yamandla kwaye isebenzisa ngokuthe ngqo i-refrigerant ukupholisa ibhetri yamandla.
1. Inkqubo yokupholisa umoya:
Kwiibhetri zamandla zokuqala, ngenxa yomthamo wazo omncinci kunye nobuninzi bamandla, iibhetri ezininzi zamandla zazipholiswa kukupholisa umoya.Isifudumezi soMoya sePTC) yahlulwe yangamacandelo amabini: ukupholisa umoya wendalo kunye nokupholisa umoya ngokunyanzelwa (kusetyenziswa ifeni), kwaye isebenzisa umoya wendalo okanye umoya obandayo kwikhabhathi ukupholisa ibhetri.
Abameli abaqhelekileyo beenkqubo ezipholisiweyo ngumoya yiNissan Leaf, iKia Soul EV, njl.njl.; okwangoku, iibhetri ze-48V zezithuthi ze-48V micro-hybrid zihlala zibekwe kwindawo yabakhweli, kwaye zipholiswa ngumoya opholileyo. Ulwakhiwo lwenkqubo yokupholisa umoya lulula, iteknoloji ikhulile, kwaye ixabiso liphantsi. Nangona kunjalo, ngenxa yobushushu obuncinci obuthathwa ngumoya, ukusebenza kwayo kotshintshiselwano lobushushu kuphantsi, ubushushu obufanayo bangaphakathi bebhetri abulungile, kwaye kunzima ukufikelela kulawulo oluchanekileyo lobushushu bebhetri. Ke ngoko, inkqubo yokupholisa umoya ngokubanzi ifanelekile kwiimeko ezinomgama omfutshane wokuhamba ngenqanawa kunye nobunzima besithuthi esilula.
Kuyafaneleka ukukhankanya ukuba kwinkqubo epholisiweyo ngumoya, uyilo lwe-air duct ludlala indima ebalulekileyo kwisiphumo sokupholisa. Ii-air ducts zahlulwe ngokubanzi zibe zii-air ducts ezilandelelanayo kunye nee-air ducts ezilandelelanayo. Ulwakhiwo lwe-serial lulula, kodwa ukumelana likhulu; ulwakhiwo oluhambelanayo luyinkimbinkimbi ngakumbi kwaye luthatha indawo engakumbi, kodwa ukufana kokusasazwa kobushushu kulungile.
2. Inkqubo yokupholisa yolwelo
Imo yokupholisa ulwelo ithetha ukuba ibhetri isebenzisa ulwelo lokupholisa ukutshintshiselana ubushushu (Isifudumezi sePTC esipholileyo). Isipholisi singahlulwa sibe ziintlobo ezimbini ezinokuqhagamshelana ngqo neseli yebhetri (ioyile yesilicon, ioyile yecastor, njl.njl.) kwaye ziqhagamshelane neseli yebhetri (amanzi kunye ne-ethylene glycol, njl.njl.) ngeetshaneli zamanzi; okwangoku, isisombululo esixutyiweyo samanzi kunye ne-ethylene glycol sisetyenziswa ngakumbi. Inkqubo yokupholisa ulwelo ngokubanzi yongeza i-chiller ukuze ihambelane nomjikelo wokufriji, kwaye ubushushu bebhetri bususwa nge-refrigerant; izinto zayo eziphambili yi-compressor, i-chiller kunye ne-impompo yamanzi yombaneNjengomthombo wamandla okupholisa, i-compressor imisela amandla okutshintshiselana kobushushu kwenkqubo yonke. I-chiller isebenza njengotshintshiselwano phakathi kwe-refrigerant kunye nolwelo lokupholisa, kwaye ubungakanani botshintshiselwano lobushushu bumisela ngokuthe ngqo ubushushu bolwelo lokupholisa. Ipompo yamanzi imisela isantya sokuhamba kwe-coolant kwipayipi. Okukhona isantya sokuhamba sikhawuleza, kokukhona ukusebenza kokudlulisa ubushushu kuphucuka, kwaye ngokuchaseneyo.
