Mfundo Yogwira Ntchito ya DC Kulipiritsa Milu Yamagalimoto Atsopano Amagetsi

1. Gulu la milu yolipiritsa

TheAC yochapira muluamagawa mphamvu ya AC kuchokera pagulu lamagetsi kupita kucharger moduleya galimotoyo kudzera mu chidziwitso chokhudzana ndi galimoto, ndicharger modulepagalimoto amawongolera mphamvu yopangira batire yamagetsi kuchokera ku AC kupita ku DC.

TheMfuti ya AC (Type1, Type2, GB/T) zaMalo opangira ACili ndi mabowo 7, mabowo 7 ali ndi zitsulo zothandizira magawo atatuMalo opangira magalimoto amagetsi a AC(380V), mabowo 7 ali ndi mabowo 5 okha okhala ndi zitsulo zokhala ndi gawo limodziAC chojambulira(220V), mfuti zopangira AC ndizocheperako kuposaDC charger mfuti(CCS1, CCS2, GB/T, Chademo).

TheDC charger muluamasintha mphamvu ya AC ya gululi yamagetsi kukhala mphamvu ya DC kuti azilipiritsa batire yamagetsi yagalimoto polumikizana ndi galimotoyo ndi chidziwitso, ndikuwongolera mphamvu yotulutsa mulu wothamangitsa molingana ndi woyang'anira batire pagalimoto.

Pali mabowo 9 pamfuti ya DC yolipiritsaMalo opangira ma DC, ndipo mfuti yojambulira ya DC ndi yayikulu kuposa mfuti ya AC.

2. Mfundo yofunikira yoyendetsera milu ya DC

Muyeso wamakampani "NB/T 33001-2010: Technical Conditions for Non-on-board Conduction Chargers for Electric Vehicles" yoperekedwa ndi National Energy Administration, ikuwonetsa kuti zoyambira zaDC ev chargerzikuphatikizapo: gawo la mphamvu, unit control unit, metering unit, charger mawonekedwe, magetsi mawonekedwe ndi anthu-makompyuta mogwirizana mawonekedwe. Chigawo chamagetsi chimatanthawuza gawo la DC chojambulira, ndipo gawo lowongolera limatanthawuza wowongolera mulu wothamangitsa. Monga chida chophatikizira dongosolo, kuwonjezera pazigawo ziwiri za "DC charger module” ndi “kuwongolera mulu wowongolera"Kupanga maziko aukadaulo, kapangidwe kake ndi chimodzi mwazofunikira kwambiri pakupanga kodalirika kwa mulu wonsewo." "Charging mulu controller" ali m'gulu la zida zophatikizika ndiukadaulo wamapulogalamu, ndipo "DC charging module" imayimira kupindula kwakukulu kwaukadaulo wamagetsi amagetsi m'munda wa AC/DC.

Njira yoyambira yolipirira ndi: kunyamula voteji ya DC kumapeto onse a batri, kulipiritsa batire ndi mphamvu yayikulu nthawi zonse, voteji ya batire imakwera pang'onopang'ono komanso imakwera pang'onopang'ono, ikukwera mpaka pamlingo wina, mphamvu ya batri imafika pamtengo wodziwika bwino, SoC imafika 95% (kwa mabatire osiyanasiyana, mosiyana), ndikupitiliza kulipiritsa batire ndi voteji pafupipafupi komanso pang'ono. "Voteji imakwera, koma batire silimadzadza, ndiye kuti silikudzaza, ngati pali nthawi, mutha kusinthana ndi kamphindi kakang'ono kuti mulemeretse." Kuti muzindikire njira yolipirirayi, mulu wolipiritsa uyenera kukhala ndi "DC charging module" kuti apereke mphamvu ya DC potengera ntchito; Ndikofunikira kukhala ndi "charging mulu controller" kuti muwongolere "mphamvu-pa, shutdown, voltage output, and output current" ya charger module; Ndikofunikira kukhala ndi "screen touch" monga mawonekedwe a makina a anthu kuti apereke malangizo, ndipo wolamulira adzapereka malangizo monga "mphamvu pa, shutdown, output voltage, output current" ndi malangizo ena ku module yolipira. Zosavuta mulu wolipiritsa galimoto yamagetsizomveka kuchokera pamlingo wamagetsi zimangofunika kukhala ndi gawo lolipiritsa, bolodi lowongolera ndi chophimba chokhudza; Ngati malamulo monga mphamvu pa, shutdown ndi output voltage] output current apangidwa kukhala makiyibodi angapo pa charging module, ndiye charging module akhoza kulipiritsa batire.

Thegawo lamagetsi la charger ya DCimakhala ndi dera loyambira ndi gawo lachiwiri. Kulowetsa kwa chipika chachikulu ndi magawo atatu osinthira magetsi, omwe amasinthidwa kukhala ovomerezeka mwachindunji ndi gawo lacharging (rectifier module) pambuyo pa chowotcha dera lolowera ndi mita yamphamvu ya AC, kenako ndikulumikiza fuse ndiev charger mfutikulipiritsa galimoto yamagetsi. Dera lachiwiri lili ndi amulu wothamangitsa galimoto yamagetsiwolamulira, wowerengera makhadi, chinsalu chowonetsera, mita ya DC, ndi zina zotero. Dera lachiwiri limaperekanso "kuyambitsa" kulamulira ndi ntchito ya "emergency stop"; Kuwala kwa chizindikiro kumapereka "standby", "charging" ndi "full" zizindikiro; Monga chida cholumikizirana ndi makompyuta amunthu, chiwonetserochi chimapereka kusuntha kwamakhadi, kuyika ma modesedwe oyitanitsa ndi ntchito zoyambira kuyimitsa.

Mfundo yamagetsi ya milu yolipiritsa ya DC imafotokozedwa mwachidule motere:

• Ma module opangira okha pakali pano ndi 15kW okha, omwe sangathe kukwaniritsa zofunikira za mphamvu, ndipo amafuna ma modules ambiri opangira kuti agwire ntchito limodzi, ndipo amafunika kukhala ndi basi ya CAN kuti akwaniritse kugawidwa kwamakono kwa ma modules angapo;
• Kuthandizira kwa gawo lolipiritsa kumachokera ku gridi yamagetsi, yomwe ili ndi mphamvu yamagetsi, yomwe imakhudza gululi mphamvu ndi chitetezo chaumwini, makamaka chitetezo chaumwini, m'pofunika kukhazikitsa chosinthira mpweya (dzina la sayansi ndi "pulasitiki chipolopolo dera wosweka"), mphezi chitetezo lophimba kapena ngakhale kutayikira lophimba pamapeto athandizira;
• Kutulutsa kwa mulu wothamangitsa ndi voteji yayikulu komanso yaposachedwa kwambiri, batire ndi electrochemical, yosavuta kuphulika, kuteteza chitetezo cha misoperation, zotulutsa ziyenera kukhala ndi fuse;
• Nkhani zachitetezo ndizofunikira kwambiri, kuphatikiza pamiyezo yomwe ili kumapeto kwa zolowetsa, zokhoma zamakina ndi zotsekera zamagetsi ziyenera kukhalapo, kuyezetsa kwa kutchinjiriza kuyenera kukhalapo, ndipo kukana kutulutsa kuyenera kukhalapo;
• Kaya batire imavomereza kuyitanitsa sikudziwika ndi mulu wothamangitsa, koma ndi ubongo wa batri, BMS. BMS ikupereka malangizo kwa woyang'anira "ngati aloleza kulipiritsa, kuletsa kuyitanitsa, kuchuluka kwa magetsi ndi magetsi omwe angavomerezedwe", ndipo wolamulirayo amatumiza ku gawo lacharge. Chifukwa chake, ndikofunikira kukhazikitsa kulumikizana kwa CAN pakati pa wowongolera ndi BMS, ndi kulumikizana kwa CAN pakati pa wowongolera ndi gawo lolipira;
• Mulu wolipiritsa uyeneranso kuyang'aniridwa ndi kuyang'aniridwa, ndipo wolamulira ayenera kulumikizidwa kumbuyo kudzera pa WiFi kapena 3G / 4G ndi ma modules ena oyankhulana pa intaneti;
• Ndalama yamagetsi yolipiritsa si yaulere, ndipo mita iyenera kukhazikitsidwa, ndipo wowerenga khadi amafunikira kuti azindikire ntchito yolipira;
• Payenera kukhala chowunikira chowoneka bwino pa chipolopolo cha milu yolipiritsa, nthawi zambiri nyali zowunikira zitatu, zomwe zikuwonetsa kuyitanitsa, kulakwa ndi magetsi motsatana;
• Kapangidwe ka ma air duct a milu yolipiritsa ya DC ndiyofunikira. Kuphatikiza pa chidziwitso cha mapangidwe, mapangidwe a mpweya amafunikira kuti fani ikhale yoyikidwa mu mulu wothamangitsira, ngakhale pali fan mkati mwa gawo lililonse lacharging.
