1. Isingeniso ku-DC ukushaja inqwaba
Eminyakeni yamuva, ukukhula okusheshayo kwezimoto zikagesi (evs) kuqhube isidingo sezixazululo ezisebenza kahle nezinobuhlakani. I-DC ishaja inqwaba, eyaziwa ngamakhono abo okushaja okusheshayo, ingaphambili lalolu shintsho. Ngentuthuko kwezobuchwepheshe, amashaja asebenzayo we-DC manje aklanyelwe ukwenza kahle isikhathi sokushaja, ukuthuthukisa ukusetshenziswa kwamandla, futhi anikeze ukuhlanganiswa komthungo namagridi ahlakaniphile.
With the continuous increase in market volume, the implementation of bidirectional OBC (On-Board Chargers) not only helps alleviate consumer concerns about range and charging anxiety by enabling fast charging but also allows electric vehicles to function as distributed energy storage stations. Lezi zimoto zingabuyisa amandla kugridi, zisize ekunikezelweni okuphezulu kanye nokugcwaliswa kwesigodi. Ukushaja okusebenzayo kwezimoto zikagesi nge-DC Fast Charger (DCFC) kuyindlela enkulu yokuqhakambisa izinguquko zamandla avuselelekayo. Iziteshi zokushaja ezisheshayo zihlanganisa izingxenye ezahlukahlukene ezifana namandla okusiza asizi, izinzwa, ukuphathwa kwamandla, namadivayisi wokuxhumana. Ngasikhathi sinye, izindlela zokukhiqiza eziguquguqukayo ziyadingeka ukuze zihlangabezane nezidingo zokushaja izimoto ezihlukile zikagesi, zingeza ukuxaka ekuklameni kwe-DCFC kanye neziteshi ze-Ultra-ezisheshayo.
Umehluko phakathi kokushaja kwe-AC kanye nokushaja kwe-DC, ngokushaja kwe-AC (uhlangothi lwesobunxele lwe-Figure 2), xhuma i-OBC ibe yi-AC aclet, futhi i-OBC iguqula i-DC efanelekile. Ngokushaja kwe-DC (ohlangothini lwesokudla sabalindi 2), okuthunyelwe ukushaja kukhokhisa ibhethri ngqo.
2. I-DC ishaja uhlelo lwezinhlelo zenqwaba
(1) Izakhi zomshini eziphelele
(2) Izingxenye zohlelo
(3) Umdwebo weBlock Block
(4) Ukushaja Inqwaba Subsystem
I-Level 3 (L3) I-DC Fast Charger Bypass The On-Board Charger (OBC) yemoto kagesi ngokushaja ibhethri ngqo ngohlelo lokuphathwa kwebhethri le-EV (BMS). Lokhu kudlula kuholela ekwandeni okukhulu kwejubane lokushaja, ngamandla okukhipha ishaja kusuka ku-50 KW kuya ku-350 kw. I-voltage kagesi evelayo ngokuvamile iyahluka phakathi kwe-400V ne-800V, nge-EVS entsha ethambekele ezinhlelweni zebhethri ezingama-800V. Kusukela ama-L3 DC asheshayo amashaja aguqula ama-voltage angu-AC amathathu wokufaka we-AC, asebenzisa ukulungiswa kwe-AC-DC Power Factor Factor (PFC), okubandakanya isiguquli se-DC-DC-DC. Lokhu kukhishwa kwe-PFC kuxhunyaniswa nebhethri lemoto. Ukufezekisa ukuphuma kwamandla aphezulu, amamojula amaningi wamandla amaningi avame ukuxhumeka ngokufana. Inzuzo enkulu ye-L3 DC Amashaja okusheshayo ukuncishiswa okukhulu ngesikhathi sokushaja izimoto zikagesi
I-Charging Pile Core iyisiguquli esiyisisekelo se-ACC. Siqukethe isigaba se-PFC, i-DC ibhasi nemodyuli ye-DC-DC

3. Ukushaja i-Ple Scenario Scheme
(1) Uhlelo lokushaja lwe-Optical Storage
Njengoba amandla okushaja kwezimoto zikagesi akhuphuka, umthamo wokusatshalaliswa kwamandla eziteshini zokushaja uvame ukulwa nokufunwa. Ukubhekana nalolu daba, uhlelo lokushaja olususelwa ekutoreji olusebenzisa ibhasi le-DC seluvele. Lolu hlelo lusebenzisa amabhethri e-lithium njengeyunithi yokugcina amandla futhi esebenzisa ama-EMS we-EMERE ENGECE AMS (ama-Energy Management System) ukuze alinganise futhi asebenzise ukulethwa kanye nokufunwa kukagesi phakathi kwegridi, amabhethri wokugcina, kanye nezimoto zikagesi. Ngokwengeziwe, uhlelo lungahlanganisa kalula nezinhlelo ze-Photovoltaic (PV), ukuhlinzeka ngezinzuzo ezibalulekile ku-Peak kanye ne-Off-Peak Electricity Priping kanye nokunwetshwa kwamandla wegridi, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwamandla.
(2) Uhlelo lokushaja lwe-V2G
Ubuchwepheshe bezimoto-to-grid (v2g) busebenzisa amabhethri e-eV ukugcina amandla, ukusekela igridi yamandla ngokunika amandla ukusebenzisana phakathi kwezimoto kanye negridi. Lokhu kunciphisa uhlobo olubangelwa ukuhlanganisa imithombo yamandla emikhulu evuselelwe kanye nokushaja okusakazekile kwe-eV, ekugcineni kwathuthukisa ukuqina kwegridi. Ngokwengeziwe, ezindaweni ezinjengomakhelwane bendawo yokuhlala kanye nezindawo ezihhovisi, izimoto eziningi zikagesi zingasebenzisa amanani entengo ephakeme kanye ne-off-peak, nikeza amandla ashukumisayo, futhi ahlinzeke ngamandla wesipele, konke ngohlelo lwe-EMCECED Management). Kwamakhaya, ubuchwepheshe bemoto-to-home (v2h) bungaguqula amabhethri e-EV abe yisixazululo sokugcina amandla ekhaya.
(3) ku-oda uhlelo lokushaja
Uhlelo lokushaja olu-odilwayo lusebenzisa iziteshi eziphakeme ezisheshayo zokushaja, ezilungele ukufakwa okuhlanganisiwe okudingayo njengeTransit yomphakathi, amatekisi, kanye namaketa wezinto. Amashejuli wokushaja angenziwa ngokwezifiso ngokuya ngezinhlobo zezimoto, ngokushaja okwenzeka ngesikhathi sokusebenza kukagesi okuphezulu kuya kwezindleko eziphansi. Ngokwengeziwe, uhlelo lokuphatha oluhlakaniphile lungasetshenziswa ukuhambisa ukuphathwa kwemikhumbi okumaphakathi.
4.Ukucabanga kwentuthuko yentuthuko
.
Iziteshi zokushaja ezisuselwa ekusatshalaliswe kuzo zizosebenza njengokungeza okubalulekile kwinethiwekhi yokushaja ethuthukisiwe. Ngokungafani neziteshi eziphakathi nendawo lapho abasebenzisi bafuna ngenkuthalo amashaja, lezi ziteshi zizohlangana ngezindawo abantu asevele bevakashele. Abasebenzisi bangakhokhisa izimoto zabo ngesikhathi sokuhlala eseluliwe (imvamisa ngaphezulu kwehora), lapho ukushaja okusheshayo kungabucayi. Amandla akhokhisa lezi ziteshi, ngokuvamile asukela ku-20 kuye kwangama-30 kW, anele izimoto zabagibeli, anikeze amandla afanelekayo okuhlangabezana nezidingo eziyisisekelo.

Ngokushintshwa kwezimoto eziphakeme zikagesi kagesi, kunesidingo esicindezelayo sokwandisa i-voltage ephezulu yokushaja kwenqwaba yokushaja kuya ku-1000v ukwamukela ukusetshenziswa okujwayelekile kwamamodeli aphezulu we-vol. Lokhu kuhamba kusekela ukuthuthukiswa kwengqalasizinda okudingekayo kweziteshi zokushaja. I-1000V ekhipha iVoltage Standard ithole ukwamukelwa okubanzi embonini yemodyuli yokushaja, futhi abakhiqizi ababalulekile bathuthuka ngokuqhubekayo amamojula wokushaja we-1000V aqhubekela phambili ngokuqhubeka kwalesi sicelo.
I-LinkPrower iye yanikezelwa ekuhlinzekeni i-R & D kufaka phakathi isoftware, i-Hardware nokubukeka kwe-AC / DC Electric Vehicle Courler Courler Piles iminyaka engaphezu kwengu-8. Sithole i-ETL / FCC / FCC / CE / CC / CB / CR25 / RCM CIREATE. Usebenzisa isoftware ye-OCPP1.6, siqede ukuhlolwa nabahlinzeki bePlatform ye-100 OCPP. Sithuthukise i-OCPP1.6J kwi-OCPP2.0.1, kanye nesosixazululo sezohwebo sezohwebo sifakwe module ye-IEC / iso15118, okuyisinyathelo esiqinile sokuthola ukushaja kwe-v2g bi-dethahali.
Esikhathini esizayo, imikhiqizo ephezulu yezobuchwepheshe njengezinqwaba zokushaja imoto kagesi, izinhlelo ze-solar photovoltaic, kanye ne-Lithium ye-Lithium Energy Storage Systems (Bess) izothuthukiswa ukuhlinzeka ngezinga eliphakeme lezixazululo ezihlanganisiwe zamakhasimende emhlabeni jikelele.
