UmGaqo wokuSebenza we-DC wokuTshaja iiMfumba zeZithuthi zaMandla amatsha

1. Ukuhlelwa kweemfumba zokutshaja

II-AC yokutshaja imfumbaisasaza amandla e-AC ukusuka kwigridi yamandla ukuya kwiimodyuli yokutshajayesithuthi ngokusebenzisa ulwazi kunye nesithuthi, kunyeimodyuli yokutshajakwisithuthi silawula amandla okutshaja ibhetri yamandla ukusuka kwi-AC ukuya kwi-DC.

IUmpu otshajayo we-AC(Uhlobo1, Uhlobo2, GB/T) ngenxaIzikhululo zokutshaja ze-ACinemingxuma yesi-7 yesiphelo, imingxuma esi-7 ineetheminali zentsimbi ukuxhasa isigaba esithathuIzikhululo zokutshaja iimoto zombane ze-AC(380V), imingxuma esi-7 inemingxuma emi-5 kuphela enezitenari zentsimbi zinenqanaba elinyeAC ev tshaja(220V), i-AC yokutshaja imipu incinci kuneDC ukutshaja imipu(CCS1, CCS2, GB/T, Chademo).

IDC ukutshaja imfumbaiguqula amandla e-AC yegridi yamandla kumandla e-DC ukuhlawula ibhetri yamandla esithuthi ngokudibana nesithuthi ngolwazi, kwaye ilawula amandla okukhutshwa kwemfumba yokutshaja ngokomphathi webhetri kwisithuthi.

Kukho 9 imingxuma terminal kwi DC ukutshaja umpu forizikhululo zokutshaja ze-DC, kunye ne-DC yokutshaja umpu mkhulu kunompu wokutshaja we-AC.

2. Umgaqo osisiseko wokusebenza we-DC wokutshaja iimfumba

Kwimigangatho yoshishino "NB / T 33001-2010: Iimeko zobuGcisa kwiiTshaja zeNgcaciso ze-Non-on-board conduction for Electric Vehicles" ezikhutshwe yi-National Energy Administration, kucaciswa ukuba ukubunjwa okusisiseko kweDC ev tshajaibandakanya: iyunithi yamandla, iyunithi yokulawula, iyunithi yokulinganisa, ujongano lokutshaja, ujongano lonikezelo lwamandla kunye nojongano lokusebenzisana kwabantu nekhompyuter. Iyunithi yamandla ibhekisa kwimodyuli yokutshaja ye-DC, kwaye iyunithi yolawulo ibhekisa kumlawuli wengqumba yokutshaja. Njengemveliso yokudibanisa inkqubo, ukongeza kumacandelo amabini "Imodyuli yokutshaja yeDC” kunye “ukutshaja imfumba yesilawuli"ebandakanya i-core core, i-structural design nayo enye yezona ngongoma eziphambili zoyilo lokuthembeka kwemfumba yonke." Umlawuli we-pile "Ukutshaja" uyingxenye ye-hardware edibeneyo kunye nobuchwepheshe be-software, kwaye "imodyuli yokutshaja ye-DC" imele impumelelo ephezulu yeteknoloji yombane we-elektroniki kwintsimi ye-AC / DC.

Inkqubo esisiseko yokutshaja yile: layisha i-voltage ye-DC kuzo zombini iziphelo zebhetri, ukutshaja ibhetri ngesantya esiphezulu sangoku, amandla ombane ebhetri ngokuthe chu kwaye anyuke kancinci, anyuke ukuya kuthi ga kwinqanaba elithile, amandla ombane ebhetri afikelela kwixabiso eliqhelekileyo, i-SoC ifikelela kuma-95% (ngeebhetri ezahlukeneyo, ezahlukeneyo), kwaye iyaqhubeka nokutshaja ibhetri ngamandla ombane rhoqo kunye nencinci yangoku. "I-voltage iyenyuka, kodwa ibhetri ayigcwali, oko kukuthi, ayigcwali, ukuba kukho ixesha, ungatshintshela kumbane omncinci ukuze uyityebise." Ukuze uqonde le nkqubo yokutshaja, imfumba yokutshaja kufuneka ibe “nemodyuli yokutshaja ye-DC” ukunika amandla e-DC ngokomsebenzi; Kuyimfuneko ukuba ube "nomlawuli wemfumba yokutshaja" ukulawula "umbane, ukuvala, umbane ophumayo, kunye nombane ophumayo" wemodyuli yokutshaja; Kuyimfuneko ukuba ube ne "touch screen" njenge-interface yomshini womntu ukukhupha imiyalelo, kwaye umlawuli uya kukhupha imiyalelo efana ne "power on, shutdown, output voltage, output current" kunye neminye imiyalelo kwimodyuli yokutshaja. Eyona ilula imfumba yokutshaja isithuthi sombanekuqondwa ukusuka kwinqanaba lombane kuphela kufuneka ube nemodyuli yokutshaja, ibhodi yokulawula kunye nesikrini sokuchukumisa; Ukuba imiyalelo enje ngombane wokuvula, ukuvala kunye nemveliso yombane] imveliso yangoku yenziwa kwiibhodi zebhodi ezininzi kwimodyuli yokutshaja, ngoko imodyuli yokutshaja inokutshaja ibhetri.

Iinxalenye yombane yetshaja ye-DCiquka isekethe yokuqala kunye nesekethe yesibini. Igalelo lelophu ephambili yinqanaba elithathu elitshintshayo langoku, eliguqulwa libe langoku elithe ngqo elamkelekileyo kwimodyuli yokutshaja (imodyuli yokulungisa) emva kokuba igalelo le-breaker circuit kunye ne-AC smart imitha yamandla, kwaye emva koko idibanisa i-fuse kunyeev ishaja umpuukuhlawula isithuthi sombane. Isekethe yesibini ine-aimfumba yokutshaja imoto yombaneisilawuli, umfundi wekhadi, isikrini sokubonisa, imitha ye-DC, njl. Isiphaluka sesibini sikwabonelela ngolawulo lwe-"start-stop" kunye nomsebenzi "wokuyeka ngokukhawuleza"; Isibane somqondiso sinika imiqondiso yesimo "sokulinda", "ukutshaja" kunye "nokugcwala"; Njengesixhobo sokusebenzisana nekhompyutha yomntu, isiboniso sibonelela ngokuswayipha kwekhadi, ukusetwa kwemowudi yokutshaja kunye nemisebenzi yokulawula yokuqalisa.

Umgaqo wombane we-DC wokutshaja iimfumba ushwankathelwa ngolu hlobo lulandelayo:

• Imodyuli enye yokutshaja okwangoku i-15kW kuphela, engakwazi ukuhlangabezana neemfuno zamandla, kwaye idinga iimodyuli ezininzi zokutshaja ukuze zisebenze kunye ngokufanayo, kwaye kufuneka zibe nebhasi ye-CAN ukufezekisa ukwabelana kwangoku kweemodyuli ezininzi;
• Igalelo lemodyuli yokutshaja livela kwigridi yamandla, eyi-high-power power supply, ebandakanya igridi yamandla kunye nokhuseleko lomntu, ngokukodwa ukhuseleko lomntu, kuyimfuneko ukufakela iswitshi yomoya (igama lezenzululwazi yi "plastic shell circuit breaker"), umbane wokukhusela umbane okanye ukutshintshela ukuvuza ekupheleni kwegalelo;
• Ukukhutshwa kwemfumba yokutshaja i-voltage ephezulu kunye nephezulu yangoku, ibhetri i-electrochemical, kulula ukuqhuma, ukukhusela ukhuseleko lwe-misoperation, imveliso kufuneka ibe ne-fuse;
• Imiba yokhuseleko iyona nto iphambili, ngaphezu kwemilinganiselo ekupheleni kokufakwayo, ukukhiya oomatshini kunye nezitshixo ze-elektroniki kufuneka zibe khona, uvavanyo lwe-insulation kufuneka lube khona, kwaye ukuchasana nokukhutshwa kufuneka kube khona;
• Ukuba ibhetri iyakwamkela ukutshajiswa akumiselwa yingqumba yokutshaja, kodwa bubuchopho bebhetri, iBMS. I-BMS ikhupha imiyalelo kumlawuli "ukuba uvumele ukutshaja, nokuba ukuphelisa ukutshaja, ubungakanani be-voltage kunye ne-current enokwamkelwa", kwaye umlawuli emva koko uyikhuphe kwimodyuli yokutshaja. Ngoko ke, kuyimfuneko ukuphumeza unxibelelwano lwe-CAN phakathi komlawuli kunye ne-BMS, kunye nonxibelelwano lwe-CAN phakathi komlawuli kunye nemodyuli yokutshaja;
• Imfumba yokutshaja nayo ifuna ukujongwa kwaye ilawulwe, kwaye umlawuli kufuneka aqhagamshelwe ngasemva nge-WiFi okanye i-3G/4G kunye nezinye iimodyuli zonxibelelwano lwenethiwekhi;
• Intlawulo yombane yokutshaja ayisimahla, kwaye kufuneka kufakwe imitha, kwaye umfundi wekhadi kufuneka aqonde umsebenzi wokuhlawula;
• Kufuneka kubekho ukukhanya okucacileyo kwigobolondo lemfumba yokutshaja, ngokuqhelekileyo izibane zesalathisi ezintathu, ezibonisa ukutshaja, impazamo kunye nokunikezelwa kwamandla ngokulandelelanayo;
• Uyilo lombhobho womoya we-DC wokutshaja iimfumba ngundoqo. Ukongeza kulwazi lwesakhiwo, uyilo lwe-air duct lufuna ukuba ifeni ifakwe kwimfumba yokutshaja, nangona kukho i-fan ngaphakathi kwimodyuli nganye yokutshaja.
