Yintoni iBattery System Testing?
Umfo wenkonzo yasendle ufowuna esithi i-forklift ayiyi kuvulwa. I-BMS itshixelwe ngaphandle. Umthengi utyhola ibhetri. Kuvela ukuba umntu ushiye ipakethi ehleli kwindawo yokugcina impahla engatshisiyo ngeholide, iqondo lobushushu lehla ngaphantsi komqobo, kwaye inkqubo yala ukuvala abafowunelwa abaphambili. Ukusebenza njengoko kuyilwe. Olu luvavanyo lwenkqubo yebhetri lwenza umsebenzi walo.
Uvavanyo lwesixokelelwano sebhetri lubandakanya izinto ezintathu ezenzeka ikakhulu ngokungabonakali kumsebenzisi wokugqibela: self-ukuxilongwa phambi kokuba ipakethe iphile, uqwalaselo lwe-insulation ngelixa isebenza, kunye nokuqinisekiswa kwe-interlock eqinisekisa ukuba akukho nto ilahlekileyo. Ngamnye ukho ngenxa yokuba kukho into engahambanga kakuhle entsimini, ngokufuthi ngokwaneleyo ukuba ibe yimfuneko eqhelekileyo. I-GB 18384-2020 e-China, i-ISO 6469-3 kumazwe ngamazwe. Ayizongcebiso ezi.
Self -Diagnostics Phambi kwayo nayiphi na enye into
Xa ucofa isitshixo sokutshintsha kwiforklift yombane, i-BMS ayithethi nje ukubamba abafowunelwa bavalwe kwaye banethemba lokona. Kukho ulandelelwano olubaleka kuqala, ludla ngokugqibezela ngaphantsi kwemizuzwana emihlanu, ngamanye amaxesha ngokukhawuleza. Inkqubo yokuvota kwiqela ngalinye leseli yevoltage kunye nobushushu, ijonga ukuba iibhodi zamakhoboka ziyanxibelelana na, kwaye iqhuba ubhaqo wokunamathela kwi-contactor ngaphambi kokuzama ukuvala nantoni na.
Imiqobo yokuSebenza ebalulekileyo
Ifestile yombane
2.0V - 4.5V
Ngokwemida yeseli. Ngaphandle kolu luhlu luthintela ukusebenza.
Uluhlu lweTemp
-40 isidanga - 80 isidanga
Imida yokhuseleko lwemodyuli yokuthintela iziganeko ezishushu.
Ifestile yombane iqinile. Amandla ombane weseli kufuneka ahlale phakathi kwe-2.0V kunye ne-4.5V okanye ipakethe ayizukuphila. Uluhlu lobushushu bemodyuli yi-40℃ukuya kwi-80 degree. La ayingomanani angenasizathu atsalwa kwiphepha elithile. Ngaphantsi kwe-2V kuthetha ukuba iseli ikhutshwe ngokunzulu okanye yonakele, awufuni ukunyanzela okwangoku ngaloo nto. Ngaphezulu kwe-4.5V kuthetha intlawulo egqithisileyo okanye impazamo yomlinganiselo, nokuba yeyiphi na indlela kukho into engalunganga. Siye sabona iipakethi zibuya neseli enye kwi-4.6V ngelixa ezinye ziqhelekileyo. Isiphene sokuvelisa kwiseli, i-BMS yasibamba ngaphambi kokuba ibe sisiganeko esishushu.
Ubhaqo lokuncamathelisa umnxibelelanisi aluhoywa de kube lulutho. Uvavanyo lusebenza ngokulinganisa i-voltage kwi-contactor terminals xa i-contactor iyalelwa ukuba ivule. Umbane okhoyo uthetha ukuba umsinga uyaqukuqela, nto leyo ethetha ukuba isinxibelelanisi esidityanisiweyo sivalwe ngexesha lomsitho wangaphambili ophezulu{2}}wangoku. Ayikwazi ukulawula isinxibelelanisi esidityanisiweyo. Ayinakuqhawula ngokukhuselekileyo ipakethi. Iforklift engavumiyo ukuyivula iyacaphukisa. I-forklift engavumi ukucima iyingozi.
Ixesha lisebenza ngolu hlobo: I-BMU iqalisa, ilinde imizuzwana eyi-0.1, ingene{1}}yokuzijonga, iqhuba kuzo zonke iimeko. Ukuba yonke into idlula kwimizuzwana emi-5, abafowunelwa abaphambili bayavala. Ukuba akunjalo, impazamo yokuqalisa, ipakethe ihlala iqhawukile. Abanye abathengi bakhalaza malunga nokulibaziseka kokuqalisa. Sichaza ukuba imizuzwana emihlanu inexabiso eliphantsi kunomlilo webhetri.
Ukujongwa kwe-Insulation kumalunga nokuvuza kwangoku, hayi nje ukuchasana
Iinkqubo zebhetri zombane ophezulu zidada xa zithelekiswa nechassis yesithuthi. Akukho nxibelelwano ngabom phakathi kwebhasi ye-DC kunye nomhlaba. Xa isigqumathelo sisonakala-ukungena kokufuma, ukunxitywa kwentambo, ungcoliseko{3}}olukhoyo luqalisa ukuvuza kwi-chassis. Chukumisa indawo engalunganga ngexesha elingalunganga kwaye ube yinxalenye yaloo sekethi. Kungenxa yoko le nto i-GB 18384-2020 ifuna ubuncinci be-100Ω ngevolthi yombane wenkqubo. Ipakethi ye-500V ifuna ubuncinci i-50kΩ phakathi kwepali kunye nomhlaba we-chassis.
Izibalo zivela kwi-IEC/TR 60479-1, eyaseka i-2mA njengomqobo apho imbono yomntu yombane wombane iqala khona. Gcina ukuvuza ngaphantsi koko kwaye uqhagamshelwano alukho bungozi ngoko nangoko. Ngaphezu koko kwaye izinto ziba mandundu ngokukhawuleza. Umgangatho unika umda wobunjineli ukuba usebenze ngawo.
Zine iindlela ezikhoyo zokulinganisa ukunganyangeki kwe-insulation kwizicelo zemoto. Indlela yombane oncedisayo idinga umthombo wangaphandle we-110V DC, yenza nzima inkqubo, kwaye ayikwazi ukwahlula ukuba yeyiphi ipali enempazamo. Indlela yangoku yoluvo isebenza kuphela xa umthwalo wangoku uqukuqela, ayinamsebenzi ngexesha -lokuqala lokuhlola. Indlela yokuxhathisa ibhulorho yeyona nto isetyenziswa kakhulu yi-BMS yeemoto ngoku. Qhagamshela izixhasi ezilungelelanisiweyo phakathi kwebhasi ye-DC kunye ne-chassis, tshintsha phakathi kolungelelwaniso, ubale ukufakwa kwe-insulation ukusuka kwiziphumo zokwahlula amandla ombane. Isebenza ngokuqhubekayo ngexesha lokusebenza kodwa inendawo engaboniyo xa ukuchasana kwepali okulungileyo kunye nokubi kwenzeka ukuba kulingane.
Indlela yokutofa amandla ombane ilungisa loo ndawo ingaboniyo ngokubeka ngaphezulu-isignali ye-AC esezantsi{1}}idla ngokuba yi-10 ukuya kwi-100Hz-kwisekethi yombane ophezulu kunye nempendulo yokulinganisa kwireferensi ye-chassis. Isebenza kungakhathaliseki i-symmetry kwi-insulation degradation. Isebenza naxa ibhetri ivaliwe kumthwalo. Kunzima ngakumbi ukuphumeza, iziphumo ezichanekileyo.
Nokuba yeyiphi na indlela oyisebenzisayo, i-BMS kufuneka yenze okuthile ngolwazi. I-Insulation ngaphezu kwe-500Ω/V, ukusebenza okuqhelekileyo. Phakathi kwe-100Ω/V kunye ne-500Ω/V, isilumkiso kwideshibhodi, mhlawumbi inqande imisebenzi ethile. Ngaphantsi kwe-100Ω/V, imeko yempazamo. Nokuba inkqubo iwacima amandla kwangoko okanye ivumela umqhubi ukuba aqhwalele ekhaya kuxhomekeke kwisantya sesithuthi kunye nemo yokusebenza. Awufuni iforklift efa phakathi{9}}nephalethi emoyeni.
I-Voltage Interlock Loop ephakamileyo ibamba iiNgxaki zoomatshini
Ukujongwa kwe-insulation kuphatha ukuhla kancinci kancinci. I-HVIL iphatha uqhawulo lonxibelelwano ngesiquphe. Isidibanisi sitsalwe sakhululeka ngexesha longquzulwano. Ikhava yesondlo isusiwe ngaphandle kokulandela inkqubo yokutshixa. Intambo eshukumayo iphuma kwilatshi yayo.
Ukuphunyezwa kuqhuba isignali yokulinga umbane ophantsi ngezikhonkwane ezinikezelweyo kuzo zonke -isiqhagamshelo sevoltage ephezulu kwisistim. Ezi zikhonkwane zimfutshane ngoomatshini kunonxibelelwano lwamandla. Xa ukhulula isinxibelelanisi, i-interlock yesiphaluka ivula kuqala, abafowunelwa bamandla bahlula okwesibini. I-BMS ibona isekethe evulekileyo, iyalela bonke abafowunelwa ukuba bavuleke, amandla ombane aphezulu ahla phambi kokuba abafowunelwa bamandla bahlukane ngokwasemzimbeni. Akukho arc kubuso bokudibanisa. Akukho ngozi kwigcisa.
Ukubaluleka kwexesha
Oku kuvakala kulula de ucinge ngexesha. Ifestile yempendulo ilinganiswa ngeemilliseconds. Inkqubo idinga ukubona ikhefu, uthathe isigqibo malunga nokuba wenze ntoni, kwaye abafowunelwa bomyalelo bavule ngokukhawuleza kunokuba isinxibelelanisi sinokutsalwa ngokwahlukeneyo. Kwiziqhagamshelo ezingaphezulu kwe-400V kuhlala kukho uqhagamshelo lwesibini lomatshini olunyanzela ukuba unqumame ngabom{4}}kufuneka ucinezele ukhupho, ulinde, uze utsale{5}}ukunika inkqubo yolawulo ixesha lokusabela.
Zimbini ii-topology ezikhoyo. I-loop ye-Series idibanisa yonke indawo yokungena kwisekethe enye eqhubekayo. I-wiring elula, ikhefu elinye naphi na livula i-loop yonke, kodwa awukwazi ukuxelela ukuba yeyiphi ikhonkco enempazamo ngaphandle kokuhlolwa ngokomzimba. Ukubeka iliso okunxuseneyo ngaphezulu kwe-CAN kuvumela umnxibelelanisi ngamnye ukuba axele imeko yawo ngokuzimeleyo. I-wiring engaphezulu, intsonkothe ngakumbi, kodwa uyazi kakuhle apho ingxaki ikhoyo. Ukumbiwa kwemigodi kunye nezicelo zenkxaso yomhlaba wesikhululo seenqwelomoya zithande ukuya kwindlela enxuseneyo kuba isixhobo sikhulu kwaye isiphene salapha sigcina ixesha.
Iindlela zokungaphumeleli eziqhelekileyo esizibonayo: i-pin corrosion evela ekungeneni kokufuma, ukungonelanga kwamandla okulinganisa ukusuka kwizindlu ezidityanisiweyo zekhonkco, ukudinwa kwekhebula ukusuka kwindlela embi evumela ukuguquguquka okuphindaphindiweyo. Le yimiba yokufakela kunye nokugcinwa, kungekhona imiba yoyilo, kodwa ibonisa njengeempazamo ze-HVIL kungakhathaliseki ukuba ziziphi na iimpazamo.
Kutheni le nto ibalulekile kwiMisebenzi yeeFlethi
Ipakethi elayo ukuqala ayixhaphazi. Ipakethi eqala xa kungafanelekanga ukuba yingozi. Uvavanyo lwenkqubo yebhetri lukhona ukunqanda isiphumo sesibini ngokuvumela esokuqala.
Uxilongo longeza iindleko kwi-BMS. Iziqhagamshelo zokuqhagamshelwa zixabisa ngaphezulu kweziqhagamshelo eziqhelekileyo. I-insulation monitoring circuit ngokwayo yazisa indlela yokumelana ne-parallel ethoba kancinane ukugquma kwenkqubo. Olu lurhwebo lobunjineli olukhoyo ngenxa yokuba enye -iipakethi zokuthumela ngaphandle kolu khuseleko{4} idala uxanduva akukho mntu ufuna ukuyiphatha.
Kubathengi abavavanya ababoneleli ngebhetri, imibuzo omawuyibuze ayikho malunga nekhemistri yeseli okanye amabango obomi bomjikelo. Ezo zinto zibalulekile, kodwa zizikhonkwane zetafile. Imibuzo etyhila isakhono somthengisi imalunga neemeko ezibukhali. Kwenzeka ntoni nge - 30℃? Kwenzeka ntoni ukuba iqela leseli liyaphuma kwibhalansi ngexesha lokugcinwa? Kwenzeka ntoni ukuba umntu uthe ngempazamo wanqumla iingcingo zemvakalelo ngexesha lolungiso? Umthengisi oneempendulo-ezithile, iimpendulo zobugcisa ezinedatha yovavanyo-mhlawumbi uye wakha iipakethi ezaneleyo ukuze abone ezi ngxaki ebaleni.
Uvavanyo lwenkqubo yebhetri ayilophawu lokubhengeza. Ziziseko ezingundoqo ezisebenza ngokuchanekileyo xa kungekho nto ingahambi kakuhle kwaye zibambe iingxaki phambi kokuba zibe ziziganeko xa kukho into eyenzekayo. Isiphumo esihle kukuba awuyiboni ukuba iyasebenza.
