9. Nceda ugcwalise ibhetri emva kokuyisebenzisa.
Qalisa ukutshaja amandla:
Nceda usebenzise umbane onikezelweyo okhethekileyo xa utshaja. Ngaphambi kokuyisebenzisa okokuqala, nceda ubize isixhobo iiyure ezili-12. Ibhetri ye-lithium-ion polymer ihlala ihlawuliswa ngokupheleleyo kwiiyure ezingama-4. Akude kube kudala kusithiwa kukude, kubangcono. Ukugcinwa kwe-asidi ye-asidi engenasondlo ifuna amaxesha ahlukeneyo okutshaja ngokuxhomekeka kumthamo wemveliso, kodwa ixesha lokutshaja lihlala lide kuneloo bhetri ye-lithium polymer.
Amanyathelo okutshaja kweLithium polymer:
1. Faka iplagi yabasetyhini etshajayo ebonelelweyo kwi "starter engxamisekileyo" yokutshaja izibuko lonxibelelwano kwaye uqinisekise ukuba ikhuselekile.

5. Ukusetyenziswa kokuqala, kuyacetyiswa ukuba ubize ixesha elide.
phinda usebenzise:
Ukuze ufikelele kubomi obuphezulu benkonzo yamandla okuqalisa kwamandla emoto, kuyacetyiswa ukugcina umatshini ugcwele ngokupheleleyo ngawo onke amaxesha.Ukuba umbane awugcinwanga ugcwele ngokupheleleyo, ubomi bonikezelo lwamandla luya kufutshane.Ukuba akunjalo iyasetyenziswa, nceda uqinisekise ukuba iyabizwa kwaye iyakhululwa kwinyanga nganye ezi-3.
Umgaqo osisiseko:
Uyilo lwamandla eemoto ezininzi kufuneka lulandele eyona migaqo isisiseko xa kuyilwa, kodwa ayizizo zonke izinto eziyiliweyo eziqonda kakuhle le migaqo. Oku kulandelayo yimigaqo esisiseko esithandathu ekufuneka ilandelwe xa kuyilwa uyilo lwamandla ezithuthi.
1. Igalelo levolthi yokufaka: uluhlu lwexeshana lwevolthi yebhetri ye-12V emisela uluhlu lwevolthi yokuguqula amandla IC
Uluhlu lwevolthi yebhetri yemoto eyi-9V ukuya kwi-16V.Xa injini icinyiwe, ombane ngegama ibhetri yeemoto yi-12V; xa injini isebenza, umbane webhetri ujikeleze i-14.4V. Nangona kunjalo, phantsi kweemeko ezahlukeneyo, umbane wethutyana unokufikelela kwi-100V. Umgangatho wecandelo le-ISO7637-1 uchaza ukuhla kwamandla ombane weebhetri zemoto. Iifomathi ezibonisiweyo kuMzobo 1 kunye noMzobo 2 ziyinxalenye yeefomathi ezinikwe ngumgangatho we-ISO7637. Eli nani libonisa iimeko ezinzima ekufuneka zifezekiswe ngabaguquli bamandla ezithuthi abakwizinga eliphezulu. Ukongeza kwi-ISO7637-1, kukho iindawo ezithile zokusebenza kwebhetri kunye nemeko ezichazwe kwiinjini zegesi. Uninzi lweenkcukacha ezintsha zicetyiswa ngabavelisi abahlukeneyo be-OEM kwaye ayilandeli imigangatho yemizi-mveliso. Nangona kunjalo, nayiphi na imigangatho emitsha ifuna ukuba inkqubo ibe ne-overvoltage kunye nokhuseleko lokungabikho kwamandla.
2. Ukutshiswa kobushushu: ukusasaza ubushushu kufuneka kuyilwe ngokokusebenza okusezantsi kwesiguquli seDC-DC
Ukusetyenziswa kokujikeleza komoya okungalunganga okanye ngaphandle kokuhamba komoya, ukuba ubushushu bemo ephezulu buphezulu (> 30 ° C) kwaye kukho umthombo wobushushu (> 1W) kwindawo ebiyelweyo, isixhobo siya kukhawuleza shushu (> 85 ° C) . Umzekelo, uninzi lwezandisi-lizwi kufuneka zifakelwe kwiindawo zokufudumeza ubushushu kwaye kufuneka zibonelele ngemeko efanelekileyo yokujikeleza komoya ukukhupha ubushushu. Ukongeza, izinto zePCB kunye nendawo ethile enxibe ubhedu inceda ekuphuculeni ubushushu bokuhambisa ubushushu, ukuze kufikelelwe kwezona meko zibalaseleyo zokuchithwa kobushushu. Ukuba isinki yobushushu ayisetyenziswanga, amandla okusasaza ubushushu kwiphedi eveziweyo kwiphakheji inqunyelwe kwi-2W ukuya kwi-3W (85 ° C). Njengoko ubushushu bemo yokuma benyuka, ubushushu bokusasazeka kwamandla buya kuncipha kakhulu.
Xa umbane webhetri uguqulwa ube ngumbane ophantsi (umzekelo: ukuphuma kwe-3.3V), umlawuli olawulayo uya kudla i-75% yamandla okufaka, kwaye ukusebenza kwawo kuphantsi kakhulu. Ukubonelela nge-1W yamandla okuphuma, i-3W yamandla iya kusetyenziswa njengobushushu. Inikwe umda bubushushu obugcweleyo kunye necala / indawo yokudibana, amandla e-1W aphezulu okuphuma kwamandla aya kuncitshiswa kakhulu. Uninzi lwabaguquli bevolthi ephezulu ye-DC-DC, xa iziphumo ezikhoyo zikuluhlu lwe-150mA ukuya kwi-200mA, i-LDO inokubonelela ngokusebenza kweendleko eziphezulu.
Ukuguqula umbane webhetri ube ngumbane ophantsi (umzekelo: 3.3V), xa amandla efikelela kwi-3W, isiphelo esiguquliweyo sokutshintsha kufuneka sikhethwe, esinokunika amandla okuphuma ngaphezulu kwe-30W. Esi sesona sizathu sokuba abavelisi bamandla eemoto bahlala bekhetha ukutshintsha izisombululo zonikezelo lwamandla kunye nokwala ubugcisa obusekwe kwi-LDO.
I-Quiescent yangoku (IQ) kunye nokucinywa kwangoku (ISD)
Ngokunyuka okukhawulezayo kwenani leeyunithi zolawulo lwe-elektroniki (ii-ECUs) kwiimoto, inani elipheleleyo elisetyenzisiweyo kwibhetri yemoto nalo liyanda. Nokuba injini icinyiwe kwaye ibhetri iphelile, ezinye iiyunithi ze-ECU zisasebenza. Ukuqinisekisa ukuba i-IQ esebenzayo yangoku ikuluhlu olulawulwayo, uninzi lwabenzi be-OEM baqala ukunciphisa i-IQ ye-ECU nganye. Umzekelo, imfuno ye-EU yile: 100μA / ECU. Uninzi lwemigangatho yeemoto ze-EU ichaza ukuba ixabiso eliqhelekileyo le-ECU IQ lingaphantsi kwe-100μA. Izixhobo ezihlala zihlala zisebenza, ezinje nge-CAN transceivers, iiwotshi zexesha lokwenyani, kunye nokusetyenziswa kwe-microcontroller ngoku zizinto eziphambili ze-ECU IQ, kunye noyilo lokuhambisa umbane kufuneka luqwalasele ubuncinci bebhajethi ye-IQ.
4. Ulawulo lweendleko: Ukuyekethisa kwabavelisi be-OEM phakathi kweendleko kunye nokubalulwa yinto ebalulekileyo echaphazela ukuhanjiswa kwamandla kwezixhobo
Kwiimveliso eziveliswe ngobuninzi, indleko yinto ebalulekileyo ekufuneka ithathelwe ingqalelo kuyilo. Uhlobo lwePCB, amandla okusasaza ubushushu, ukhetho lweephakeji kunye nezinye izithintelo zoyilo eneneni zinqunyelwe kuhlahlo-lwabiwo mali lweprojekthi ethile. Umzekelo, ukusebenzisa i-4-layer board FR4 kunye nebhodi yomaleko omnye we-CM3, amandla okusasaza ubushushu bePCB aya kwahluka kakhulu.
Uhlahlo-lwabiwo mali lweprojekthi luza kukhokelela kwesinye isithintelo.Abasebenzisi banokwamkela iindleko eziphezulu ze-ECU, kodwa abayi kuchitha ixesha nemali ekuguquleni uyilo lwesiko lokuhambisa umbane. Kumaqonga amatsha ophuhliso anexabiso eliphezulu, abayili benza uhlengahlengiso olulula kuyilo lwamandla emveli olungenakulinganiswa.
5. Ubume / ubeko: I-PCB kunye nolwakhiwo lwecandelo kuyilo lonikezelo lwamandla luya kunciphisa ukusebenza ngokubanzi kombane
Uyilo lolwakhiwo, ubeko lwebhodi yesekethe, ubuntununtunu bengxolo, imiba emininzi yokudibanisa ibhodi, kunye nezinye izithintelo zoyilo ziya kuthintela uyilo lwezixhobo zombane ezihlangeneyo eziphezulu. Ukusetyenziswa kwamandla okupakisha umthwalo wokuvelisa onke amandla ayimfuneko kuya kukhokelela kwiindleko eziphezulu, kwaye ayilunganga ukudibanisa izinto ezininzi kwi-chip enye. Abaqulunqi bamandla okuhambisa umbane kufuneka balungelelanise ukusebenza kwenkqubo yonke, imiqobo yoomatshini, kunye neendleko ngokweemfuno ezithile zeprojekthi.
6. Imitha yombane
Indawo eyahluka-hlukeneyo yombane iya kuvelisa imitha ye-electromagnetic radiation.Ubungqingqwa bemitha buxhomekeke kubude nobungakanani bentsimi.Ukuphazanyiswa kombane okwenziwe yisekethe enye kuya kuchaphazela ngqo enye isekethe. Umzekelo, ukuphazamiseka kwamajelo kanomathotholo kunokubangela ukuba i-airbag ingasebenzi kakuhle Ukuze kuthintelwe ezi ziphumo zingalunganga, abavelisi be-OEM bamisele ubuninzi bemida ye-electromagnetic radiation yeeyunithi ze-ECU.
Ukugcina i-electromagnetic radiation (EMI) kuluhlu olulawulwayo, uhlobo, itopology, ukhetho lwezinto zecandelo, ubeko lwebhodi yesekethe kunye nokukhusela isiguquli seDC-DC kubaluleke kakhulu. Emva kweminyaka yokuqokelelana, abaqulunqi bamandla e-IC baphuhlise iindlela ezahlukeneyo zokunciphisa i-EMI. Ungqamaniso lwewotshi lwangaphandle, ukusebenza kwamaxesha aphezulu kunebhendi yokumodareyitha ye-AM, eyakhelwe-ngaphakathi kwi-MOSFET, itekhnoloji yokutshintsha ethambileyo, ukusasaza itekhnoloji ye-spectrum, njl.njl.
