1. Isingeniso senqwaba yokushaja ye-DC
Eminyakeni yamuva nje, ukukhula okusheshayo kwezimoto zikagesi (EVs) kuqhubekisele phambili isidingo sezixazululo zokushaja ezisebenza kahle nezihlakaniphile. Izinqwaba zokushaja ze-DC, ezaziwa ngamakhono azo okushaja ngokushesha, zihamba phambili kulolu shintsho. Ngokuthuthuka kwezobuchwepheshe, amashaja e-DC asebenza kahle manje aklanyelwe ukuthuthukisa isikhathi sokushaja, ukuthuthukisa ukusetshenziswa kwamandla, futhi anikeze ukuhlanganisa okungenazihibe namagridi ahlakaniphile.
Ngokukhula okuqhubekayo kwevolumu yemakethe, ukuqaliswa kwe-bidirectional OBC (Amashaja Asebhodini) akusizi nje kuphela ekudambiseni ukukhathazeka kwabathengi mayelana nebanga nokukhathazeka kokushaja ngokuvumela ukushaja okusheshayo kodwa futhi kuvumela izimoto zikagesi ukuthi zisebenze njengeziteshi zokugcina amandla ezisabalalisiwe. Lezi zimoto zingabuyisela amandla kugridi, zisize ekushebeni okuphezulu kanye nokugcwaliswa kwesigodi. Ukushajwa kahle kwezimoto zikagesi ngamashaja asheshayo e-DC (DCFC) kuwumkhuba omkhulu ekukhuthazeni ukushintshwa kwamandla avuselelekayo. Iziteshi zokushaja ezishesha kakhulu zihlanganisa izingxenye ezihlukahlukene ezifana nezinsiza zamandla ezisizayo, izinzwa, ukuphathwa kwamandla, namadivayisi okuxhumana. Ngesikhathi esifanayo, izindlela zokukhiqiza ezivumelana nezimo ziyadingeka ukuze kuhlangatshezwane nezidingo zokushaja eziguqukayo zezimoto ezihlukene zikagesi, okwengeza inkimbinkimbi ekwakhiweni kwe-DCFC neziteshi zokushaja ezishesha kakhulu.
Umehluko phakathi kokushaja kwe-AC nokushaja kwe-DC, ekushajweni kwe-AC (uhlangothi lwesobunxele loMdwebo 2), xhuma i-OBC endaweni yokuphuma evamile ye-AC, futhi i-OBC iguqule i-AC ibe yi-DC efanele ukuze ishaje ibhethri. Ngokushaja kwe-DC (uhlangothi lwesokudla loMdwebo 2), iposi lokushaja lishaja ibhethri ngokuqondile.
2. Ukwakheka kwesistimu yenqwaba yokushaja kwe-DC
(1) Qedela izingxenye zomshini
(2) Izingxenye zesistimu
(3) Umdwebo webhulokhi esebenzayo
(4) Uhlelo olungaphansi lwenqwaba yokushaja
Amashaja asheshayo eLeveli 3 (L3) DC adlula ishaja engaphakathi ebhodini (OBC) yemoto kagesi ngokushaja ibhethri ngokuqondile nge-EV's Battery Management System (BMS). Lokhu kudlula kuholela ekwenyukeni okukhulu kwejubane lokushaja, namandla okukhipha ishaja asukela ku-50 kW kuya ku-350 kW. Amandla kagesi okukhiphayo ngokuvamile ahluka phakathi kuka-400V kanye no-800V, nama-EV amasha athrenda kumasistimu ebhethri angu-800V. Njengoba amashaja asheshayo e-L3 DC aguqula amandla kagesi e-AC ezigaba ezintathu abe yi-DC, asebenzisa isiphetho sangaphambili se-AC-DC power factor correction (PFC), esihlanganisa isiguquli se-DC-DC esingasodwa. Lokhu okukhiphayo kwe-PFC kube sekuxhunyaniswa nebhethri lemoto. Ukuze kuzuzwe ukuphuma kwamandla aphezulu, amamojula wamandla amaningi avame ukuxhunywa ngokuhambisana. Inzuzo enkulu yamashaja asheshayo e-L3 DC ukwehla okukhulu kwesikhathi sokushaja ezimotweni zikagesi
Inqwaba yokushaja iyisiguquli esiyisisekelo se-AC-DC. Iqukethe isiteji se-PFC, ibhasi le-DC kanye ne-DC-DC module

3. Isikimu sesimo senqwaba yokushaja
(1) Isistimu yokushaja yesitoreji esibonakalayo
Njengoba amandla okushaja ezimoto zikagesi ekhula, umthamo wokusabalalisa amandla eziteshini zokushaja ngokuvamile udonsa kanzima ukuhlangabezana nesidingo. Ukuze kuxazululwe le nkinga, sekuvele uhlelo lokushaja olusekelwe kwisitoreji elisebenzisa ibhasi le-DC. Lolu hlelo lusebenzisa amabhethri e-lithium njengeyunithi yokugcina amandla futhi lusebenzisa i-EMS yasendaweni nekude (Uhlelo Lokuphathwa Kwamandla) ukuze lulinganise futhi lukhulise ukuhlinzekwa kanye nesidingo sikagesi phakathi kwegridi, amabhethri okugcina, kanye nezimoto zikagesi. Ukwengeza, isistimu ingakwazi ukuhlanganisa kalula nezinhlelo ze-photovoltaic (PV), inikeze izinzuzo ezibalulekile emananini kagesi aphezulu kanye ne-off-peak kanye nokwandiswa komthamo wegridi, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kwamandla jikelele.
(2) Isistimu yokushaja ye-V2G
Ubuchwepheshe be-Vehicle-to-Grid (V2G) busebenzisa amabhethri e-EV ukugcina amandla, ukusekela igridi yamandla ngokuvumela ukusebenzisana phakathi kwezimoto negridi. Lokhu kunciphisa ubunzima obubangelwa ukuhlanganisa imithombo emikhulu yamandla avuselelekayo kanye nokushajwa okusabalele kwe-EV, ekugcineni kuthuthukise ukuzinza kwegridi. Ukwengeza, ezindaweni ezifana nezindawo zokuhlala kanye nezakhiwo zamahhovisi, izimoto zikagesi eziningi zingasebenzisa ithuba lokubiza amanani aphezulu kakhulu, zilawule ukukhuphuka komthwalo oguquguqukayo, ziphendule isidingo segridi, futhi zinikeze amandla okulondoloza, konke ngokusebenzisa i-EMS (Energy Management System) ukulawula. Emizini, ubuchwepheshe be-Vehicle-to-Home (V2H) bungaguqula amabhethri e-EV abe yisixazululo sokugcina amandla ekhaya.
(3) Uhlelo lokushaja olu-odwe
Isistimu yokushaja e-oda ngokuyinhloko isebenzisa iziteshi zokushaja ezinamandla aphezulu, ezilungele izidingo zokushaja ezigxilile njengezokuthutha zomphakathi, amatekisi, nemikhumbi yezokuthutha. Amashejuli wokushaja angenziwa ngendlela oyifisayo ngokusekelwe ezinhlotsheni zezimoto, kanti ukushajwa kwenzeka ngesikhathi samahora kagesi ongaphakeme kakhulu ukuze kwehle izindleko. Ukwengeza, uhlelo lokuphatha oluhlakaniphile lungasetshenziswa ukuze kuqondiswe ukuphathwa kwemikhumbi okumaphakathi.
4.Isikhathi esizayo sokuthuthuka
(1) Ukuthuthukiswa okudidiyelwe kwezimo ezihlukene kulekelelwa iziteshi zokushaja ezimaphakathi + ezisabalalisiwe ezivela eziteshini zokushaja ezimaphakathi eyodwa
Iziteshi zokushaja ezisatshalaliswa ezisekelwe endaweni zizosebenza njengesengezo esibalulekile kunethiwekhi yokushaja ethuthukisiwe. Ngokungafani neziteshi ezimaphakathi lapho abasebenzisi befuna khona amashaja, lezi ziteshi zizohlanganiswa nezindawo abantu asebezivakashele kakade. Abasebenzisi bangashaja izimoto zabo ngesikhathi sokuhlala okunwetshiwe (imvamisa engaphezu kwehora), lapho ukushaja okusheshayo kungabalulekile khona. Amandla okushaja alezi ziteshi, ngokuvamile asukela ku-20 kuya ku-30 kW, anele izimoto zabagibeli, ahlinzeka ngezinga elifanelekile lamandla ukuze ahlangabezane nezidingo eziyisisekelo.
(2) 20kW imakethe yamasheya amakhulu ukuya ku-20/30/40/60kW ukuthuthukiswa kwemakethe yokucushwa okuhlukahlukene
Ngokushintshela ezimotweni zikagesi ezinamandla kagesi aphezulu, kunesidingo esicindezelayo sokwandisa amandla kagesi wokushaja aphezulu ezinqwaba zokushaja aye ku-1000V ukuze kuhlangatshezwane nokusatshalaliswa okubanzi kwesikhathi esizayo kwamamodeli anamandla kagesi. Lesi sinyathelo sisekela ukuthuthukiswa kwengqalasizinda edingekayo yeziteshi zokushaja. Izinga le-voltage ephumayo engu-1000V selithole ukwamukelwa okubanzi embonini yemojula yokushaja, futhi abakhiqizi abakhulu baqhubeka bethula amamojula okushaja angu-1000V aphezulu ukuze ahlangabezane nalesi sidingo.
I-Linkpower inikezelwe ekuhlinzekeni nge-R&D okuhlanganisa isofthiwe, ihadiwe nokubukeka kwezinqwaba zokushaja izimoto zikagesi ze-AC/DC iminyaka engaphezu kwengu-8. Sithole izitifiketi ze-ETL / FCC / CE / UKCA / CB / TR25 / RCM. Sisebenzisa isofthiwe ye-OCPP1.6, siqede ukuhlola ngabahlinzeki benkundla ye-OCPP abangaphezu kwe-100. Sithuthukise i-OCPP1.6J yaba yi-OCPP2.0.1, futhi isixazululo se-EVSE sezentengiselwano sifakwe imojula ye-IEC/ISO15118, okuyisinyathelo esiqinile ekufezeni ukushaja kwe-V2G bi-directional.
Esikhathini esizayo, imikhiqizo yobuchwepheshe obuphezulu efana nezinqwaba zokushaja imoto kagesi, i-solar photovoltaic, nezinhlelo zokugcina amandla ebhethri ye-lithium (BESS) izothuthukiswa ukuze inikeze izinga eliphezulu lezixazululo ezididiyelwe kumakhasimende emhlabeni jikelele.
