Chii chinonzi high-voltage power distribution unit yemotokari?
Chiyuniti chekugovera mota ine simba guru (PDU) chinhu chakakosha muhurongwa hwemagetsi makuru emotokari itsva, chinonyanya kukosha pakugovera magetsi nekutarisira kuti zvive nechokwadi chekuti zvikamu zvemotokari zvine simba guru zvinoshanda zvakachengeteka uye zvakagadzikana.
Mabasa makuru
Youdaoplaceholder0 Kugoverwa kwesimba uye manejimendi: Govera zvakachengeteka high-voltage direct current kumidziyo yakasiyana-siyana yemagetsi, senge madrive motors, macharging systems, nezvimwewo.
Youdaoplaceholder0 yekuchaja uye yekudzora kuburitsa: Inotarisira maitiro ekuchaja uye kuburitsa system ine voltage yakawanda, kusanganisira kudzivirira overload, short-circuit dziviriro uye high-voltage sampling function.
Youdaoplaceholder0 kudzora kwevoltage yakaderera : kudzora simba-pa-on uye kutarisa mamiriro ezvikamu zvevoltage ine simba rakawanda kuburikidza nemasekete ane voltage shoma.
Dhizaini yekubvisa kupisa yeYoudaoplaceholder0: Mamwe maPDU anoshandisa magadzirirwo ekutonhodza mvura kana kutonhora kwemhepo kuti ave nechokwadi chekuti zvinodiwa zvekuparadza kupisa kwezvikamu zvine simba guru.
Zvimiro zvechivako
PDU inogona kubatanidza mabasa akadai seDC-DC conversion modules, kuchaja mamodules eOBC, uye BMS main control, zvichiita kuti pave nedhizaini yakabatana zvikuru. Semuenzaniso, mamodules matatu-mu-mumwe uye mana-mu-mumwe anogona kubatanidza mayuniti akawanda anoshanda kuti agutse zvinodiwa zvemhando dzakasiyana dzemotokari.
Chigadziko chemotokari chinopa simba guru (PDU) ndicho chinhu chikuru chinodzora simba guru mumotokari itsva, chichiita mabasa ekugovera simba uye kuchengetedza kuchengetedzeka. Aya ndiwo mabasa ayo makuru:
Kugoverwa kwesimba remagetsi rine simba guru
PDU inogovera simba remagetsi rinobuda nemagetsi (300-800V) rinobuda nebhatiri remagetsi kuzvinhu zvakakosha zvakaita semota inofambisa, charger iri mubhodhi (OBC), DC/DC converter, uye electric air conditioning compressor. Semuenzaniso, drive motor controller inoita 60% yemagetsi anobuda, uye imwe yose inoiswa kune masisitimu ekuwedzera akadai sekuchaja nekudziyisa.
Nzira yekudzivirira kuchengetedzeka
Kusanganisira overcurrent, short circuit, overvoltage uye overheat dziviriro:
Dziviriro ye Youdaoplaceholder0 overcurrent : Kana magetsi adarika 120% yemutengo wakayerwa kwemasekondi maviri, contactor huru inobviswa uye fuse inoputika
Youdaoplaceholder0 Dziviriro yepfupi-yedunhu : Kana impedance yakaderera pane 100mΩ, dunhu rinogurwa muma microseconds
Youdaoplaceholder0 Dziviriro yekupisa kwakanyanya: Kana tembiricha yebhazi remhangura ikadarika 110℃, zvishoma nezvishoma inoderedza mutoro kana kudzima simba
Kuona insulation yeYoudaoplaceholder0: inogona kuona njodzi yekukundikana kweinsulation <500Ω/V uye kukonzera alarm
Kubatanidzwa uye kutonga kwehurongwa
Inobatanidza DC/DC conversion module, charging control unit uye BMS main control function, uye inotsigira modular design. Mirayiridzo yeVCU inogamuchirwa kuburikidza neCAN bus kuti iwane power-on/power-off sequence control ye high-voltage circuit (nguva yekupindura <50ms), uye hurongwa hwekugovera simba hunogadziriswa nenzira inochinja (sekukoshesa kuvharwa kwemitoro isiri yakakosha panguva yekuchaja).
Zviratidzo zvekushanda
Kushanda zvakanaka kwekugovera ≥98% (mutoro wakaderera)
Simba rekudzivirira rinogona kumira 2500V AC kwemasekonzi makumi matanhatu pasina kukanganiswa
Hupenyu hwemuchina hwe relay ine voltage yepamusoro hunopfuura 100,000 cycles
Inotsigira basa rekufananidza mutoro unochinjika (kuderedza kushandiswa kwesimba ne5-8%)
Kukanganisika kweyuniti yekugovera mota ine voltage yakawanda kunowanzo tungamira kumasisitimu emagetsi asina kujairika, kukanganiswa kwekuchaja kana kukuvara kwezvikamu zvemagetsi, izvo zvinoratidzwa se:
Chiitiko chemhosva
Youdaoplaceholder0 Kukundikana kwesimba remagetsi: Mota haigone kumhanya zvakanaka, uye kumhanya kwakanyanya kwakaganhurirwa (semuenzaniso, kumhanya mubhokisi iri i40km/h chete)
Youdaoplaceholder0 Kuchaja zvisina kujairika : Kuchaja kweAC/DC kwakanganiswa kana kuti hakugone kutanga (tarisa zvikanganiso mumutsara wecontactor wekuchaja kana sensor)
Youdaoplaceholder0 Alarm yezviridzwa : Inoratidza "High voltage system fault" kana "power system fault" prompt
Youdaoplaceholder0 Dziviriro yezvikamu zvemagetsi : Sisitimu iyi inodzima yega circuit ine voltage yakawanda kudzivirira kukuvara kwakawanda (senge ma controllers emota, mabhatiri emagetsi, nezvimwewo)
Zvikonzero zvakajairika
Youdaoplaceholder0 high-voltage interlock circuit open circuit : zviratidzo zvekutarisa zvisina kujairika zvinokonzera kukiya kwesisitimu (senge kusabatana zvakanaka kwemutsetse, kuputsika kwecircuit breaker)
Zvikanganiso zvemukati zvebhokisi rekugovera: contactor yebhokisi rekugovera rine voltage yakawanda inonamira, uye kuona kwekubuda kwemvura kunokundikana
Youdaoplaceholder0 Kutenderera kwenguva pfupi kana kuwandisa zvakanyanya: kukuvara kwechikamu chekudzivirira chewaya ine simba guru kunokonzera kutenderera kwenguva pfupi pasi
Nzira dzekuongorora chirwere
Youdaoplaceholder0 Verenga kodhi yekukanganisa : Wana kodhi yekukanganisa chaiyo (yakadai seP1E0300, B042900) kuburikidza nedhikodha
Kuedzwa kwechiratidzo cheYoudaoplaceholder0 : Tarisa kana chiratidzo cheduty cycle che high-voltage interlock circuit chakajairika (zvishandiso zvehunyanzvi zvinodiwa)
Kuongororwa kwekuyedzwa kwedunhu reYoudaoplaceholder0 : Tarisa maitiro ezvikamu zvemagetsi (senge mamiriro emagetsi emutongi wemota) mumamiriro ezvinhu ekutadza akaedzwa
Zvinokurudzirwa kubata sangano renyanzvi rekugadzirisa zvinhu kuti riongorore macircuit ane simba guru kudzivirira njodzi dzinogona kukonzerwa nekuzviparadzanisa.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
