Kuwona Ukadaulo Wabwino wa Mulu Wochulukira wa DC: Kukupangirani Malo Olipiritsa Anzeru

Kusiyana pakati pa AC charger ndi DC charger, pa AC charger (kumanzere kwa Chithunzi 2), pulagi OBC mu AC outlet wamba, ndipo OBC amasintha AC kukhala DC yoyenera kulipiritsa batire. Pakuyitanitsa kwa DC (mbali yakumanja kwa Chithunzi 2), positi yolipira imayitanitsa batire mwachindunji.

2. DC kulipiritsa mulu dongosolo zikuchokera

(1) Malizitsani zigawo zamakina

(2) Zigawo za dongosolo

(3) Chiwonetsero cha block block

(4) Kuthamangitsa mulu wocheperako

Ma charger othamanga a Level 3 (L3) DC amalambalala chojambulira chapa-board (OBC) chagalimoto yamagetsi potchaja batire mwachindunji kudzera pa EV's Battery Management System (BMS). Kudutsa kumeneku kumabweretsa kuwonjezeka kwakukulu kwa liwiro lacharging, ndi mphamvu yotulutsa ma charger kuyambira 50 kW mpaka 350 kW. Magetsi otulutsa nthawi zambiri amasiyana pakati pa 400V ndi 800V, pomwe ma EV atsopano akulowera kumayendedwe a batri a 800V. Popeza ma charger othamanga a L3 DC amasintha magetsi a magawo atatu a AC kukhala DC, amagwiritsa ntchito AC-DC power factor correction (PFC) kutsogolo, komwe kumaphatikizapo chosinthira cha DC-DC chakutali. Kutulutsa kwa PFC uku kumalumikizidwa ndi batire lagalimoto. Kuti mukwaniritse kutulutsa kwamphamvu kwamphamvu, ma module amphamvu angapo nthawi zambiri amalumikizidwa mofanana. Phindu lalikulu la ma charger othamanga a L3 DC ndikuchepetsa kwambiri nthawi yolipirira magalimoto amagetsi

Pachimake mulu wolipira ndi chosinthira choyambirira cha AC-DC. Ili ndi gawo la PFC, basi ya DC ndi module ya DC-DC

3. Kulipiritsa mulu zochitika chiwembu

(1) Optical storage charger system

Mphamvu yolipiritsa yamagalimoto amagetsi ikachulukirachulukira, mphamvu yogawa magetsi pamalo othamangitsira nthawi zambiri imavutikira kuti ikwaniritse zofunikira. Kuti tithane ndi vutoli, njira yolipirira yotengera kusungirako yomwe imagwiritsa ntchito basi ya DC yatulukira. Dongosololi limagwiritsa ntchito mabatire a lithiamu monga gawo losungiramo mphamvu ndipo limagwiritsa ntchito EMS (Energy Management System) yakumalo komanso yakutali kuti ikwaniritse bwino komanso kuwongolera magetsi pakati pa gululi, mabatire osungira, ndi magalimoto amagetsi. Kuphatikiza apo, makinawa amatha kuphatikizika mosavuta ndi makina a photovoltaic (PV), omwe amapereka zabwino zambiri pamitengo yamagetsi apamwamba komanso osakwera kwambiri komanso kukulitsa mphamvu ya grid, potero kumapangitsa kuti mphamvu zonse ziziyenda bwino.

(2) V2G charging system

Ukadaulo wa Vehicle-to-Grid (V2G) umagwiritsa ntchito mabatire a EV kusungira mphamvu, kuthandizira gridi yamagetsi pothandizira kulumikizana pakati pa magalimoto ndi gridi. Izi zimachepetsa kupsinjika komwe kumabwera chifukwa chophatikiza magwero akuluakulu amphamvu zongowonjezwwdwanso ndi kuchuluka kwa ma EV kulipiritsa, pamapeto pake kumapangitsa kukhazikika kwa gridi. Kuonjezera apo, m'madera monga malo okhalamo ndi maofesi, magalimoto ambiri amagetsi amatha kutengerapo mwayi pamitengo yamtengo wapatali komanso yosakwera kwambiri, kuyendetsa bwino kukwera kwa katundu, kuyankha zofuna za gridi, ndi kupereka mphamvu zosunga zobwezeretsera, kupyolera mu EMS (Energy Management System) kulamulira. Kwa mabanja, ukadaulo wa Vehicle-to-Home (V2H) ungasinthe mabatire a EV kukhala njira yosungiramo mphamvu yanyumba.

(3) Dongosolo loyitanitsa

Njira yolipirira yoyitanitsa imagwiritsa ntchito malo othamangitsira othamanga kwambiri, omwe ali abwino pazosowa zolipiritsa monga mayendedwe apagulu, ma taxi, ndi zonyamula katundu. Nthawi zolipiritsa zitha kusinthidwa malinga ndi mitundu yamagalimoto, ndipo kulipiritsa kumachitika nthawi yamagetsi yopanda mphamvu kuti muchepetse mtengo. Kuphatikiza apo, njira yowongolera mwanzeru imatha kukhazikitsidwa kuti ithandizire kuyendetsa bwino zombo zapakati.

4.Chitukuko chamtsogolo

(1) Kukula kogwirizana kwa zochitika zosiyanasiyana zomwe zikuphatikizidwa ndi malo othamangitsira apakati + ogawidwa kuchokera kumalo opangira ma charger apakati

Masiteshoni otengera komwe akupita adzakhala ngati chowonjezera pa netiweki yolipirira. Mosiyana ndi masiteshoni apakati pomwe ogwiritsa ntchito amafunafuna ma charger mwachangu, masiteshoniwa aziphatikizana ndi malo omwe anthu amapitako kale. Ogwiritsa ntchito amatha kulipiritsa magalimoto awo nthawi yayitali (nthawi zambiri kupitilira ola limodzi), pomwe kulipiritsa mwachangu sikofunikira. Mphamvu zolipiritsa za masiteshoniwa, nthawi zambiri kuyambira 20 mpaka 30 kW, ndizokwanira pamagalimoto onyamula anthu, zomwe zimapereka mphamvu zokwanira kuti zikwaniritse zofunikira.

(2) 20kW lalikulu gawo msika kuti 20/30/40/60kW zosiyanasiyana kasinthidwe msika chitukuko

Ndikusintha kupita ku magalimoto amagetsi okwera kwambiri, pakufunika kufunikira kowonjezera ma voliyumu othamangitsa a milu yolipiritsa mpaka 1000V kuti agwirizane ndi kufalikira kwamtsogolo kwa mitundu yothamanga kwambiri. Kusunthaku kumathandizira kukweza kwachitukuko kofunikira pamasiteshoni othamangitsira. Mphamvu yamagetsi ya 1000V yalandira kuvomerezedwa kwakukulu mumakampani opanga ma module, ndipo opanga makiyi akubweretsa pang'onopang'ono ma module a 1000V othamanga kwambiri kuti akwaniritse izi.

Linkpower yadzipereka kuti ipereke R&D kuphatikiza mapulogalamu, zida ndi mawonekedwe a milu yamagetsi yamagetsi ya AC/DC kwa zaka zopitilira 8. Tapeza ziphaso za ETL / FCC / CE / UKCA / CB / TR25 / RCM. Pogwiritsa ntchito mapulogalamu a OCPP1.6, tamaliza kuyesa ndi opereka nsanja oposa 100 a OCPP. Tapititsa patsogolo OCPP1.6J ku OCPP2.0.1, ndipo njira yamalonda ya EVSE yakhala ikugwiritsidwa ntchito ndi module ya IEC/ISO15118, yomwe ndi sitepe yolimba kuti tikwaniritse V2G bi-directional charger.

M'tsogolomu, zipangizo zamakono monga milu yamagetsi yamagetsi, photovoltaic ya dzuwa, ndi lithiamu batire mphamvu yosungirako mphamvu (BESS) zidzapangidwa kuti apereke mlingo wapamwamba wa njira Integrated kwa makasitomala padziko lonse.
