Mfundo Yogwirira Ntchito Yoyatsira Magalimoto Atsopano a Mphamvu ya DC

1. Kugawa milu yolipirira

TheMulu wochapira wa ACimagawa mphamvu ya AC kuchokera ku gridi yamagetsi kupita kugawo lolipiritsaya galimotoyo kudzera mu kulumikizana kwa chidziwitso ndi galimotoyo, ndigawo lolipiritsapa galimotoyo imalamulira mphamvu yochaja batire yamagetsi kuchokera ku AC kupita ku DC.

TheMfuti yochapira ya AC (Type1, Type2, GB/T) chifukwa chaMalo ochapira ma ACIli ndi mabowo 7 omalizira, mabowo 7 ali ndi ma terminal achitsulo othandizira magawo atatuMalo ochapira magalimoto amagetsi a AC(380V), mabowo 7 ali ndi mabowo 5 okha okhala ndi ma terminal achitsulo omwe ali ndi gawo limodziChojambulira cha AC ev(220V), mfuti zochapira za AC ndi zazing'ono kuposaMfuti zoyatsira za DC (CCS1, CCS2, GB/T, Chademo).

TheMulu wochapira wa DCImasintha mphamvu ya AC ya gridi yamagetsi kukhala mphamvu ya DC kuti ipereke mphamvu ya batri yamagetsi yagalimoto polumikizana ndi galimotoyo ndi chidziwitso, ndipo imayang'anira mphamvu yotulutsa ya mulu woyatsira malinga ndi woyang'anira batri pagalimotoyo.

Pali mabowo 9 omalizira pa mfuti ya DC yochapiraMalo ochapira a DC, ndipo mfuti yochapira ya DC ndi yayikulu kuposa mfuti yochapira ya AC.

2. Mfundo yoyambira yogwirira ntchito ya DC charging piles

Mu muyezo wamakampani "NB/T 33001-2010: Mikhalidwe Yaukadaulo ya Ma Charger Osayendetsa Magalimoto Amagetsi Osayendetsedwa" woperekedwa ndi National Energy Administration, zafotokozedwa kuti kapangidwe kake koyambiraChojambulira cha DC evzikuphatikizapo: gawo lamagetsi, gawo lowongolera, gawo loyezera, mawonekedwe ochajira, mawonekedwe operekera magetsi ndi mawonekedwe olumikizirana pakati pa anthu ndi makompyuta. Gawo lamagetsi limatanthawuza gawo lochajira la DC, ndipo gawo lowongolera limatanthawuza chowongolera chochajira. Monga chinthu chophatikiza dongosolo, kuwonjezera pa zigawo ziwiri za "Gawo lolipiritsa la DC"ndi"chowongolera cha mulu wochapira"Popanga maziko aukadaulo, kapangidwe ka kapangidwe kake ndi chimodzi mwazinthu zofunika kwambiri pakupanga kodalirika kwa mulu wonse. "Chowongolera mulu wochaja" ndi cha gulu la zida zolumikizidwa ndi ukadaulo wa mapulogalamu, ndipo "module yochaja ya DC" ikuyimira kupambana kwakukulu kwa ukadaulo wamagetsi pamunda wa AC/DC.

Njira yoyambira yolipirira ndi iyi: kuyika mphamvu ya DC kumapeto onse a batri, kuyika mphamvu yamagetsi ... mulu wochapira magalimoto amagetsiKumvetsetsa kuchokera pamlingo wamagetsi kumangofunika kukhala ndi gawo lochajira, bolodi lowongolera ndi sikirini yokhudza; Ngati malamulo monga kuyatsa, kutseka ndi voteji yotulutsa] mphamvu yotulutsa yapangidwa kukhala makiyibodi angapo pa gawo lochajira, ndiye kuti gawo lochajira limatha kuchajitsa batri.

Thegawo lamagetsi la chojambulira cha DCLili ndi dera loyambira ndi dera lachiwiri. Cholowera cha dera lalikulu ndi magetsi osinthasintha a magawo atatu, omwe amasinthidwa kukhala magetsi olunjika omwe amavomerezedwa ndi gawo lochaja (module yokonzanso) pambuyo pa cholowetsa dera lotsegula ndi mita yamagetsi yanzeru ya AC, kenako amalumikiza fuse ndimfuti yojambulira ya evkuti ayambe kuyatsa galimoto yamagetsi. Chigawo chachiwiri chimakhala ndimulu wochapira galimoto yamagetsichowongolera, chowerengera makadi, chophimba chowonetsera, choyezera DC, ndi zina zotero. Chigawo chachiwiri chimaperekanso ntchito yowongolera "kuyamba-kusiya" ndi "kuyimitsa mwadzidzidzi"; Kuwala kwa chizindikiro kumapereka zizindikiro za "standby", "charging" ndi "full"; Monga chipangizo cholumikizirana ndi munthu ndi kompyuta, chiwonetserochi chimapereka swiping ya khadi, kuwongolera mawonekedwe ochaja komanso ntchito zowongolera kuyambira-kusiya.

Mfundo yamagetsi ya DC charging piles yafupikitsidwa motere:

• Module imodzi yochaja ili ndi mphamvu ya 15kW yokha, yomwe singakwaniritse zofunikira za mphamvu, ndipo imafuna ma module angapo ochaja kuti agwire ntchito limodzi nthawi imodzi, ndipo imafunika kukhala ndi basi ya CAN kuti ikwaniritse kugawana ma module angapo pakali pano;
• Cholowera cha gawo lochapira chimachokera ku gridi yamagetsi, yomwe ndi magetsi amphamvu kwambiri, okhudzana ndi gridi yamagetsi ndi chitetezo chaumwini, makamaka chitetezo chaumwini, ndikofunikira kuyika swichi ya mpweya (dzina lasayansi ndi "pulasitiki shell circuit breaker"), swichi yoteteza mphezi kapena swichi yotulutsira madzi kumapeto kwa input;
• Mphamvu yotuluka mu mulu wochapira ndi yamagetsi ambiri komanso mphamvu yamagetsi yapamwamba, batire ndi yamagetsi, yosavuta kuphulika, kuti isagwiritsidwe ntchito molakwika, mphamvu yotuluka iyenera kukhala ndi fuse;
• Nkhani zachitetezo ndizofunikira kwambiri, kuwonjezera pa miyeso yomwe ili kumapeto kwa malo olowera, maloko amakina ndi maloko amagetsi ayenera kukhalapo, mayeso oteteza kutentha ayenera kukhalapo, komanso kukana kutulutsa madzi kuyenera kukhalapo;
• Kaya batire ivomereza kuyitanitsa sizimatsimikiziridwa ndi mulu wa kuyitanitsa, koma ndi ubongo wa batire, BMS. BMS imapereka malangizo kwa wolamulira kuti "kaya alole kuyitanitsa, kaya aleke kuyitanitsa, kuchuluka kwa magetsi ndi mphamvu zomwe zingavomerezedwe", ndipo wolamulirayo amawatumiza ku module yoyitanitsa. Chifukwa chake, ndikofunikira kukhazikitsa kulumikizana kwa CAN pakati pa wolamulira ndi BMS, ndi kulumikizana kwa CAN pakati pa wolamulira ndi module yoyitanitsa;
• Mulu wochapira uyeneranso kuyang'aniridwa ndi kuyang'aniridwa, ndipo chowongolera chikuyenera kulumikizidwa kumbuyo kudzera pa WiFi kapena 3G/4G ndi ma module ena olumikizirana ndi netiweki;
• Bilu yamagetsi yolipirira si yaulere, ndipo mita imafunika kuyikidwa, ndipo wowerenga khadi amafunika kuti agwire ntchito yolipirira;
• Pamafunika kuwala kowonekera bwino pa chipolopolo cha mulu wochajira, nthawi zambiri magetsi atatu owunikira, omwe amasonyeza kuchajira, vuto ndi magetsi motsatana;
• Kapangidwe ka njira zoyendetsera mpweya zomwe zimayikidwa mu DC charging piles ndikofunikira kwambiri. Kuwonjezera pa kudziwa kapangidwe kake, kapangidwe ka njira zoyendetsera mpweya kumafuna kuti pakhale fan mu mulu wa charging, ngakhale kuti pali fan mkati mwa gawo lililonse la charging.
