Gucukumbura neza DC Kwishyuza Ikirundo Ikoranabuhanga: Gukora Sitasiyo Yubwenge Yubusa

Itandukaniro riri hagati yo kwishyuza AC no kwishyuza DC, kugirango yishyure AC (uruhande rwibumoso rwishusho 2), shyira OBC mumasoko asanzwe ya AC, hanyuma OBC ihindure AC kuri DC ibereye kugirango yishyure bateri. Kumashanyarazi ya DC (uruhande rwiburyo rwishusho 2), post yishyuza yishyuza bateri muburyo butaziguye.

2. DC kwishyuza ikirundo cya sisitemu

(1) Ibikoresho byuzuye byimashini

(2) Ibigize sisitemu

(3) Igishushanyo mbonera cyo guhagarika

(4) Kwishyuza ikirundo

Urwego rwa 3 (L3) DC byihuta byihuta byuzuza amashanyarazi (OBC) yimodoka yamashanyarazi mukwishyuza bateri binyuze muri sisitemu yo gucunga bateri ya EV (BMS). Iyi bypass iganisha ku kwiyongera gukabije kwumuvuduko, hamwe nimbaraga ziva mumashanyarazi kuva kuri 50 kW kugeza 350 kW. Umuvuduko w'amashanyarazi usanzwe uratandukanye hagati ya 400V na 800V, hamwe na EV nshya igenda yerekeza kuri sisitemu ya batiri 800V. Kubera ko amashanyarazi ya L3 DC yihuta ahindura ibyiciro bitatu byinjiza amashanyarazi muri DC, bakoresha AC-DC imbaraga zo gukosora (PFC) imbere-impera, ikubiyemo DC-DC yihariye. Ibisohoka bya PFC noneho bihuzwa na bateri yimodoka. Kugirango ugere ku mbaraga zisohoka, imbaraga nyinshi modules zikunze guhuzwa. Inyungu nyamukuru ya L3 DC yamashanyarazi yihuta nigabanuka ryinshi ryigihe cyo kwishyuza ibinyabiziga byamashanyarazi

Kwishyiriraho ikirundo cyibanze ni shingiro rya AC-DC. Igizwe nicyiciro cya PFC, bus ya DC na module ya DC-DC

Igishushanyo mbonera cya PFC

DC-DC module ikora igishushanyo mbonera

3. Kwishyuza gahunda yikirundo

(1) Sisitemu yo kubika neza

Mugihe imbaraga zo kwishyiriraho ibinyabiziga byamashanyarazi ziyongera, ubushobozi bwo gukwirakwiza amashanyarazi kuri sitasiyo yumuriro akenshi biragoye guhaza ibyifuzo. Kugira ngo iki kibazo gikemuke, hagaragaye uburyo bwo kubika bushingiye ku bubiko bukoresha bisi ya DC. Sisitemu ikoresha bateri ya lithium nkigice cyo kubika ingufu kandi ikoresha EMS yo mu karere no kure (Sisitemu yo gucunga ingufu) kugirango iringanize kandi ihindure itangwa n’ibisabwa by’amashanyarazi hagati ya gride, bateri zibikwa, n’imodoka zikoresha amashanyarazi. Byongeye kandi, sisitemu irashobora guhuza byoroshye na sisitemu ya Photovoltaque (PV), itanga inyungu zikomeye mugiciro cyumuriro wamashanyarazi no hejuru yumuriro no kwagura ubushobozi bwa gride, bityo bikazamura ingufu muri rusange.

(2) Sisitemu yo kwishyuza V2G

Ikoranabuhanga rya Vehicle-to-Grid (V2G) rikoresha bateri ya EV kugirango ibike ingufu, ishyigikira umuyoboro w'amashanyarazi ushoboza imikoranire hagati yimodoka na gride. Ibi bigabanya imbaraga ziterwa no guhuza ingufu nini nini zishobora kongera ingufu hamwe no gukwirakwiza amashanyarazi ya EV, amaherezo bikazamura imiyoboro ihamye. Byongeye kandi, mu bice nko gutura hamwe n’ibigo bikoreramo, ibinyabiziga byinshi byamashanyarazi birashobora kwifashisha ibiciro byikirenga kandi bitari hejuru, gucunga imizigo yiyongera, gusubiza ibyifuzo bya gride, no gutanga ingufu zinyuma, byose binyuze muri EMS ikomatanyije (Sisitemu yo gucunga ingufu) kugenzura. Ku ngo, tekinoroji yimodoka-murugo (V2H) irashobora guhindura bateri za EV mubisubizo byo kubika ingufu murugo.

(3) Yategetse sisitemu yo kwishyuza

Sisitemu yo kwishyuza yatumijwe ikoresha cyane cyane sitasiyo yumuriro wihuta cyane, nibyiza kubikenerwa byokwishyurwa nkibicuruzwa rusange, tagisi, hamwe n’ibikoresho bya logistique. Gahunda yo kwishyuza irashobora gutegurwa hashingiwe ku bwoko bwimodoka, hamwe no kwishyuza bikorwa mugihe cyamasaha yumuriro wamashanyarazi kugirango ibiciro bigabanuke. Byongeye kandi, sisitemu yo gucunga ubwenge irashobora gushyirwa mubikorwa kugirango horoherezwe gucunga amato.

4.Iterambere ry'ejo hazaza

Icyerekezo gishingiye ku gukwirakwiza amashanyarazi kizaba nk'inyongera y'ingirakamaro ku muyoboro wongerewe wo kwishyuza. Bitandukanye na sitasiyo ikomatanyirijwe aho abakoresha bashakisha byimazeyo charger, izi sitasiyo zizahurira ahantu abantu basuye. Abakoresha barashobora kwishyuza ibinyabiziga byabo mugihe kinini (mubisanzwe birenze isaha), aho kwishyuza byihuse ntabwo ari ngombwa. Imbaraga zo kwishyiriraho ziriya sitasiyo, ubusanzwe ziri hagati ya 20 na 30 kW, zirahagije kubinyabiziga bitwara abagenzi, bitanga urwego rwingufu zingirakamaro kugirango zihuze ibikenewe byibanze.

Hamwe no guhindukirira ibinyabiziga byamashanyarazi biri hejuru, harakenewe cyane kongera ingufu zumuriro ntarengwa wamashanyarazi kugeza kuri 1000V kugirango habeho ikoreshwa rya moderi nini cyane. Uku kwimuka gushyigikira ibikorwa remezo bikenewe byo kuzamura sitasiyo. 1000V isohoka ya voltage isanzwe yemerewe cyane muruganda rwo kwishyuza module, kandi abayikora bambere bagenda bamenyekanisha buhoro buhoro 1000V yumuriro mwinshi kugirango babone iki cyifuzo.

Linkpower yitangiye gutanga R&D harimo software, ibyuma ndetse nigaragara kumashanyarazi ya AC / DC yishyuza ibirundo mumyaka irenga 8. Twabonye ibyemezo bya ETL / FCC / CE / UKCA / CB / TR25 / RCM. Dukoresheje software ya OCPP1.6, twarangije kwipimisha hamwe nabatanga porogaramu zirenga 100 OCPP. Twazamuye OCPP1.6J kuri OCPP2.0.1, kandi igisubizo cya EVSE cyubucuruzi cyahawe module ya IEC / ISO15118, iyi ikaba ari intambwe ikomeye yo kumenya kwishyurwa V2G byerekanwa.

Mu bihe biri imbere, ibicuruzwa byikoranabuhanga buhanitse nk'ibinyabiziga bikoresha amashanyarazi, ibirundo by'izuba, hamwe na sisitemu yo kubika ingufu za Lithium (BESS) bizashyirwaho kugira ngo bitange urwego rwo hejuru rw’ibisubizo bihuriweho ku bakiriya ku isi.
