Raws li cov cuab yeej tseem ceeb rau kev xa hluav taws xob thiab kev tswj hwm, kev tsim qauv ntawm lub tsheb hluav taws xob charger ncaj qha cuam tshuam rau kev them nqi, kev nyab xeeb, thiab kev ntseeg tau. Los ntawm tag nrho cov kev xav ntawm architecture, ib lub charger feem ntau muaj tsib qhov tseem ceeb: lub zog hloov pauv, kev tswj hwm, kev sib txuas lus, kev tiv thaiv kev nyab xeeb, thiab pab pawg. Cov khoom no ua haujlwm ua ke los tsim kom muaj kev ua haujlwm zoo.
Lub zog hloov pauv hloov pauv yog "lub siab" ntawm lub charger, lub luag haujlwm hloov AC lub zog los ntawm daim phiaj hluav taws xob mus rau DC lub zog ntawm lub tsheb (los yog lub zog AC xav tau los ntawm -board charger). Ua piv txwv li DC them ceev ceev, qhov module no feem ntau siv lub siab - zaus hloov hluav taws xob topology, nrog rau tus choj rectifier, DC - DC converter, thiab lub lim dej: tus choj rectifier converts peb -theem / ib zaug-theem AC fais fab los ntawm lub zog hluav taws xob hloov mus rau DC{6} hluav taws xob tam sim no, tswj lub zog tam sim no. tsis muaj, thiab thaum kawg, lim Circuit Court outputs ruaj khov DC fais fab mov kom tau raws li qhov ceev ceev them ntawm lub tsheb roj teeb. Lub module txuas nrog IGBT lossis SiC cov khoom siv hluav taws xob, thiab lawv qhov kev hloov pauv zaus thiab cov cua kub dissipation tsim ncaj qha txiav txim siab txog qhov txwv ntawm kev them lub zog thiab ntev - lub sijhawm ua haujlwm ruaj khov.
Tus tswj module yog "lub hlwb" ntawm lub charger, muaj xws li ib tug microcontroller (MCU), ib tug digital signal processor (DSP), thiab nplooj siab chips. Nws lub luag haujlwm tseem ceeb yog khaws cov ntaub ntawv tiag - lub sijhawm xws li cov khoom siv hluav taws xob / tso zis hluav taws xob / tam sim no thiab roj teeb xwm txheej (piv txwv li, SOC, qhov kub thiab txias), thiab hloov kho lub sijhawm hloov pauv ntawm lub zog hloov pauv los ntawm algorithms los xyuas kom meej tias cov txheej txheem them raws li lub roj teeb tus yam ntxwv nkhaus, zam kev puas tsuaj los ntawm overvoltage thiab overcurrent. Tib lub sijhawm, tus tswj module yuav tsum cuam tshuam nrog lub khoos phis tawj tswj hwm (xws li lub chaw them nyiaj ua haujlwm) txhawm rau ua tiav cov lus txib pib / nres thiab tshaj tawm cov ntaub ntawv tsis raug.
Qhov kev sib txuas lus sib txuas lus yog "ntxhais" txuas lub charger rau lwm lub tshuab, txhawb nqa ntau yam kev cai xws li CAN tsheb npav, Ethernet, thiab 4G / 5G. Nws tuaj yeem ua tiav bidirectional authentication thiab parameter sib tham nrog lub tsheb BMS (Battery Management System) kom ntseeg tau tias kev them nyiaj nyab xeeb; nws tseem tuaj yeem xa cov khoom siv raws li txoj cai thiab cov ntaub ntawv siv hluav taws xob rau kev ua haujlwm platform, txhawb kev ua haujlwm hauv chaw taws teeb thiab kev saib xyuas.
Kev tiv thaiv kev nyab xeeb permeates tag nrho cov qauv, npog cov hluav taws xob cais (xws li transformers, optocouplers), overvoltage / overcurrent tiv thaiv (fuses, hluav taws xob hloov), kev saib xyuas tam sim no, thiab ntsuas kub (NTC sensors + cua txias kiv cua / kua cua txias system). Ntau cov txheej txheem tiv thaiv tsim ib qho peb - qhov thaiv kev nyab xeeb ntawm daim phiaj hluav taws xob mus rau lub tsheb.
Cov pab pawg muaj xws li tib neeg- tshuab interface (ntsuab tshuaj ntsuam, cov nyees khawm), metering module (zog metering nti), thiab chassis qauv (waterproof thiab dustproof vaj tse). Cov qauv tsim no sib npaug yooj yim ntawm kev ua haujlwm nrog ib puag ncig kev hloov pauv, ua kom ruaj khov ntawm lub charger nyob rau hauv ib puag ncig nyuaj xws li cov chaw sab nraum zoov thiab chaw nres tsheb hauv av.
Cov qauv tsim ntawm lub tsheb fais fab chargers yog qhov tseem ceeb ntawm kev sib npaug ntawm lub zog hloov pauv qhov tseeb, tswj cov lus teb ceev, thiab kev nyab xeeb dua. Nrog rau kev siv cov khoom siv silicon carbide thiab kev txawj ntse algorithms, lawv cov qauv tau hloov zuj zus mus rau kev siv zog ntau dua thiab muaj zog yoog raws, muab kev txhawb nqa ntau zog rau kev siv tsheb tshiab.
