Kwiminyaka yakutshanje, ishishini leemoto lehlabathi liye lenza inkqubela phambili enkulu ekwamkeleni izithuthi zombane (ii-EV) njengeendlela ezinomtsalane kunezithuthi zepetroli eziqhelekileyo. Ngokuthandwa kwezithuthi zombane okwandayo, kukho isidingo esikhulayo sokuphuhlisa iinkqubo zolawulo lobushushu bebhetri yezithuthi zombane (ii-EVBTMS) ezomeleleyo nezisebenzayo ukuphucula ukusebenza kwebhetri nokuqinisekisa ubomi bayo bonke.
Enye yezona zinto ziphambili ze-EVBTMS kukusetyenziswa kwezifudumezi ze-positive temperature coefficient (PTC). Ezi zifudumezi ziphambili zidlala indima ebalulekileyo ekugcineni ubushushu bebhetri obufanelekileyo kwiimeko ezibandayo kakhulu nezishushu. Ngokusebenzisa iipropati ezizilawulayo zezinto ze-PTC, ezi zifudumezi zinokubonelela ngesisombululo sokufudumeza esithembekileyo nesisebenzayo kwiintlobo ngeentlobo zezicelo zezithuthi zombane.
Ngexesha lemozulu ebandayo, iinkqubo zebhetri kwizithuthi zombane ziyawohloka ngenxa yamaqondo obushushu aphantsi.Isifudumezi sePTC esipholileyo/Isifudumezi soMoya sePTC) lungisa le ngxaki ngokufudumeza ibhetri, ukuqinisekisa ukuba ibhetri isebenza kakuhle kwaye wonyusa ukusebenza kakuhle kwesithuthi. Ubushushu obuveliswa yi-PTC heater buhambelana ngqo nobushushu bebhetri, bulungisa ukumelana kwayo ukuze kugcinwe inqanaba lobushushu elihlala lihleli nelikhuselekileyo. Ngokusasaza ubushushu ngokufanelekileyo kuyo yonke ibhetri, ii-PTC heaters zinceda ekunciphiseni ukulahleka kwamandla kwaye zigcine umgama omde wokuqhuba nokuba kwiimeko zokubanda.
Ngokwahlukileyo koko, kwiindawo ezishushu, iibhetri ze-EV zinokutshisa kakhulu ngokukhawuleza, nto leyo ebangela ukusebenza kakuhle okunciphileyo, kwaye kwezinye iimeko, zinciphise ubomi bebhetri. I-EVBTMS esebenzayo ifaka ipompo yamanzi yombane ejikeleza ngokufanelekileyo i-coolant kwiphakheji yebhetri, ilawula ubushushu obuveliswa ngexesha lokutshaja nokukhupha. Oku kukhuthaza ubushushu obulinganayo nobuzinzileyo, ikhusela ibhetri kuxinzelelo lobushushu kwaye yandise ubomi bayo. Ukongezwa kwe-heater ye-PTC kongeza isenzo sepompo yamanzi yombane ngokubonelela ngokufudumeza nokupholisa ngaxeshanye, ukuqinisekisa ukuba iphakheji yebhetri ihlala ngaphakathi koluhlu lobushushu olufanelekileyo ukuze isebenze kakuhle.
Ukudibanisa izifudumezi ze-PTC kunye neempompo zamanzi zombane kwi-EVBTMS akupheleli nje ekuphuculeni ukusebenza kwebhetri, kodwa kukwabonelela ngeenzuzo ezininzi ezongezelelweyo. Okokuqala, ukhuseleko lulonke lwesithuthi luyaphuculwa njengoko inkqubo ithintela ukuba imida yobushushu ebalulekileyo ingagqithwa, nto leyo enciphisa umngcipheko wokubaleka kobushushu kunye nomonakalo onokubakho webhetri. Okwesibini, ngokugcina ukusebenza kakuhle kweseli, ubomi bebhetri bunokwandiswa, nto leyo ekhokelela kwiindleko zokulungisa eziphantsi kunye nokusetyenziswa okuzinzileyo kwezixhobo.
Ngaphezu koko, ii-EVBTMS ezisebenzayo zinegalelo ekusetyenzisweni kwamandla ngendlela ezinzileyo njengoko zinciphisa inkunkuma yamandla ngokulawula ngokuchanekileyo amanqanaba obushushu ngaphakathi kwepakethi yebhetri. Ngokunciphisa ukusetyenziswa kwamandla agqithisileyo okubangelwa kukulawulwa kobushushu okungasebenzi kakuhle, ii-EV zinokunyusa umgama wokuqhuba kwaye zinciphise ubuninzi bokutshaja kunye nobude bexesha, ekugqibeleni zincede okusingqongileyo kunye neengxowa zabanini be-EV.
Ngamafutshane, ukuhlanganiswa kwezifudumezi ze-PTC kunyeiimpompo zamanzi zombaneUkusebenzisa iinkqubo zolawulo lobushushu bebhetri ye-EV kubalulekile ukuphucula ukusebenza nokusebenza kakuhle kwee-EV. Ezi zinto zilawula kwaye zibonelela ngokufudumeza nokupholisa, ziqinisekisa ukuba ibhetri isebenza ngaphakathi komgangatho wobushushu ofanelekileyo, yandisa ubomi bayo kwaye iphucula ukhuseleko ngokubanzi. Ngokusebenzisa i-EVBTMS eqinileyo, izithuthi zombane zinokubonelela ngenye indlela ezinzileyo nethembekileyo kunezithuthi zenjini yokutsha yangaphakathi, ngaloo ndlela zikhawulezisa ukutshintshela kwikamva eliluhlaza.
