Kuyini Ukuqapha Izinga lokushisa?
Ngichithe iminyaka emithathu ngenza ukuqinisekiswa kwephakethe kumhlinzeki we-Tier 1 ku-metro Detroit. Ukuqapha izinga lokushisa mhlawumbe kwakungu-40% walokho engangibhekana nakho usuku nosuku. Hhayi ngoba kuyinkimbinkimbi. Ngoba abantu baqhubeka beyibhixa ngendlela efanayo.
Ukuhlolwa kokuqinisekisa endaweni yelebhu.
Umbono oyisisekelo ukuthi unamathisele ama-thermistors kumaseli futhi ubuke izinombolo. Yilokho kuphela. Ama-NTC kakhulu. Kushibhile, kunembile ngokwanele, wonke umuntu uyazi ukuthi asetshenziswa kanjani. Izinkinga ziqala lapho ubuza ukuthi uzibeke kuphi nokuthi zingaki ozidingayo ngempela.
Ingcindezi yezindleko inonya. Abaphathi bohlelo bafuna izinzwa ezimbalwa. Onjiniyela abashisayo bafuna okwengeziwe. Ngahlala phakathi kwalezo zingxabano eziningi. Ngokuvamile ukuvumelana kuhlale endaweni ethile okungagculisi kuwo wonke umuntu. Izinzwa eziyisishiyagalombili zemojuli enamaseli angu-12. Wabeke kumaseli ocabanga ukuthi azoshisa kakhulu futhi uthemba ukuthi uqagele kahle.
Ukulingisa okushisayo kuhlangabezana-nezingqinamba zomhlaba zangempela.
Ukulingisa vs. Reality
Ungakwazi ukumodela lezi zinto nge-ANSYS noma ku-STAR-CCM+ kuze kuphume igazi. Ukulingisa kukutshela ukuthi amaseli amaphakathi kumojuli asebenza ngokushisa kakhulu kunomphetho. Amathebhu ashisa kakhulu kunemizimba. Akukho kulokhu okumangazayo. Lokho ukulingisa okungakutsheli ukuthi kwenzekani uma ulayini wakho wokukhiqiza ufaka unamathisele oshisayo ngokungahambisani. Noma uma iseli elivela kuqeqebana elibi linokumelana okuphakeme kancane kwangaphakathi kunamanye. Noma uma ikhasimende lifaka iphekhi emotweni enomoya odonsayo eduze kwe-multifold exhaust. Babone bobathathu.
I-Thermal Runaway ithola ukunakwa. Kuyazwakala. Iseli eliya ebalekile lilahla amandla amaningi ngokushesha okukhulu. Isistimu yokuqapha idinga ukubamba ukukhuphuka kwezinga lokushisa kusenesikhathi ukuze yenze okuthile ngakho. Vula abathintwayo. Yenza kusebenze ukucindezela uma unayo. Okungenani log yonke into ukuze ukwazi ukuthola ukuthi kwenzekeni kamuva.
Nansi into kodwa. Ukubaleka akuvamile. Okubulala amaphakethe ensimini iminyaka yokusebenza ngo-5 noma 10 degrees ukufudumala kunalokho amaseli afuna ukuba yikho. Amandla ayafiphala. Amandla ayaphela. Ngeke uwubone umlilo. Uzobona izimangalo zewaranti ngonyaka wesi-4 lapho ububanzi behla ngaphansi kokucaciswa. Ukuqapha izinga lokushisa nakho kuyabaluleka ngalokho kodwa akudli kakhulu ukuze abantu bangacabangi ngakho kakhulu.
I-BMS isampula izinga lokushisa kokuthile okufana no-1 Hz. Kwesinye isikhathi kancane. Imicimbi eshisayo kumaseli yenzeka ngamasekhondi kuya kumaminithi ngakho lokho kushesha kakhulu. Okubaluleke kakhulu ukuthi imikhawulo ibekwa kuphi.
Ukonga kakhulu futhi unciphisa amandla lapho iphekhi isenayo i-headroom. Unolaka kakhulu futhi upheka amaseli. Yonke i-OEM inamafilosofi ahlukene kulokhu. Abanye bahlose ukusebenza kahle kakhulu, abanye babeka phambili impilo ende. Ungakwazi ukubona ukuthi imoto iziphatha kanjani ngosuku olushisayo ngeshaja esheshayo.
I-Cold Reality
Isimo sezulu esibandayo empeleni sinzima kakhulu ukubhekana naso kunokushisa. Iphakethe eliku-minus 20 C cishe alinawo amandla atholakalayo. Ukumelana kwangaphakathi kuya phezulu. Amaseli awakwazi ukwamukela ukushajwa okuningi kwamanje ngaphandle kokufaka i-lithium plating engozini. Ngakho-ke udinga ukushisisa, okusho ukushisa amandla okufudumeza iphakethe ngaphambi kokuthi ulisebenzise. Ezinye izimoto ziba nemibandela ngokuzenzakalelayo lapho usetha isikhathi sokusuka. Abanye bakwenza uhlale lapho ulindile.
Ukuqapha izinga lokushisa kulowo mongo kusho ukwazi ukuthi iphekhi lifudumele ngokwanele ukuze ulisebenzise ngempela. Nokuqinisekisa ukuthi isistimu yokushisisa ayidali izindawo ezishisayo. Ukusebenzisa ihitha ye-PTC eduze kweseli eyodwa kuyilapho abanye behlala bebanda akukuhle. Ukubonile lokho futhi.
Ukuvela kobuchwepheshe bezinzwa.
Imboni iqhubekela kuzinzwa eziningi, hhayi ezimbalwa. Ngokwengxenye ngoba ama-NTC aqhubeka eshibha. Ngokwengxenye ngenxa yokuthi abantu bezibalo bafuna idatha eyengeziwe ukuze baphakele amamodeli abo okwehlisa isithunzi. Kunenkulumo mayelana ne-fiber optics ngaphakathi kwamaseli kodwa ngizokholwa ukuthi lokho sekulungile ukukhiqizwa uma ngikubona kulayini. Okwamanje zingama-thermistors kuma-cell cans nasezindaweni zokudayisa, njengoba sekuyiminyaka eyi-15.
Lonke iphakethe elibuya ensimini linenkinga eshisayo, into yokuqala esiyenzayo ukudonsa idatha yelogi. Bheka amaphrofayili okushisa aholela emcimbini. Izikhathi eziyisishiyagalolunye kweziyishumi ungabona kahle ukuthi konakelephi. I-Cell 23 ibifudumala kunomakhelwane bayo amasonto ngaphambi kokuthi yehlule. Bekumele umuntu akubambe lokho. Kodwa i-threshold yayibekwe ku-45 C futhi ayizange ibe ngaphezu kuka-42. Ngakho-ke i-BMS ayizange imake futhi akekho owabheka.
Lokho ukuqapha izinga lokushisa. Hhayi izinzwa ngokwazo. Isinqumo mayelana nokuthi wenzeni ngedatha abakunika yona.
