Imashini zishyuza imodoka zivuga ibya: 800V Sisitemu yo Kwishyuza Amashanyarazi

Uruganda rukora amamodoka: Sisitemu ya 800V yumubyigano mwinshi + kwihuta cyane kubinyabiziga byamashanyarazi birashobora kugera kumwanya wo kwishyuza muminota 10 hamwe na kilometero 300, bishobora gukemura neza impungenge zo kuzura, kandi biteganijwe ko bizaba inzira nyamukuru yo kwishyurwa byihuse. Isosiyete ikora amamodoka yo mu gihugu ndetse n’amahanga yamaze gukora imiterere ijyanye, kandi moderi nyinshi za 800V zizakorwa cyane mu 2022. Ariko ifite ibikoresho bya 800V byumuvuduko mwinshi wimodoka yishyuza mumashanyarazi asanzwe yishyuza ikirundo, umuvuduko wo kwishyurwa ntabwo ugera kubiteganijwe, birashoboka ntugere kubintu byihuta byishyurwa, bityo ikirundo cyuruhererekane rwurunigi rwinganda rugomba kuvugururwa hamwe nimpera yimodoka, ibice byinshi byumuhanda bizabyungukiramo.

Ubwa mbere, niki kwishyuza voltage nyinshi

Abakora amamodoka yimodoka: Kwishyuza byihuse ni kwishyuza byihuse, igice cyo gupima gishobora kwishyurwa inshuro (C). Ninini yo kugwiza inshuro nyinshi, igihe gito cyo kwishyuza.

Kwishyuza kugwiza (C) = kwishyuza amashanyarazi (mA) / ubushobozi bwa batiri (mAh)

Kurugero, niba ubushobozi bwa bateri ari 4000mAh naho amashanyarazi akagera kuri 8000mAh, kugwiza amashanyarazi ni 8000/4000 = 2C.

Uruganda rukora amamodoka: Kwishyura hejuru ntabwo 0% -100% yishyurwa bikorwa nubushakashatsi bugezweho. Uburyo bwiza bwo kwishyuza bugabanijwemo ibyiciro bitatu, icyiciro cya 1: mbere yo kwishyuza leta; icyiciro cya 2: amashanyarazi menshi ahoraho yishyurwa; icyiciro cya 3: kwishyuza amashanyarazi buri gihe.

Abakora amamodoka yimodoka: Icyiciro cya 1 mbere yo kwishyuza igira uruhare mukurinda selile ya bateri, icyiciro cya 2 nicyo twita icyiciro cyo kwishyuza hejuru, ingufu ziyi nzira akenshi ziri muri 20% -80%; icyiciro cya 3 guhora kwishyuza bigamije kugabanya ingufu za voltage, kubuza selile ya bateri kurenza voltage, ishobora kwangiza imiterere ya bateri.

1, Abashinzwe kwishyiriraho imodoka: kwishyuza byihuse bigomba kunoza imbaraga zumuriro wanyuma hamwe na bateri yishyuza / kugwiza

Hariho uburyo bubiri bwingenzi bwo kwishyuza kuri EVS: DC kwishyuza byihuse na AC gutinda buhoro.

Abakora amamodoka yimodoka: Kwishyuza gahoro gahoro bihuye nuburyo bwo kwishyiriraho murugo cyangwa muri parikingi yimodoka, imbaraga zo kwishyuza ni nto kuva kuri kilowati nkeya kugeza kuri kilowat nyinshi, mubisanzwe bifata amasaha 8-10 kugirango yishyurwe byuzuye. Kwishyuza gahoro gahoro ikoresha ingufu za 220V AC kuva kuri gride, ikayihindura mumashanyarazi ya DC ikoresheje imashini ya AC / DC imbere mumashanyarazi ya OBC kugirango itange bateri ya EV. Abakora amamodoka yimodoka: Bitewe nububasha buke bwo kwishyuza, imbaraga za AC / DC zihindura zubatswe mubwato bwa OBC muri rusange ziri hasi, kandi igiciro kiri hasi.

Uruganda rukora amamodoka: DC kwishyuza byihuse mubisanzwe bihuye na sisitemu yo kwishyiriraho mumihanda minini / ingendo ndende, aho amashanyarazi agera kuri kilowati amagana kandi bigatwara amasaha 1-2 gusa kugirango yishyure byuzuye. Intangiriro yumuriro wa DC ni uguhindura ingufu nyinshi AC / DC kumwanya wogushiraho byihuse, aho poste ya DC ihindura ingufu za AC ziva mumashanyarazi zikaba zifite ingufu nyinshi DC ikoresheje ikosora kugirango yishyure bateri yikinyabiziga mu buryo butaziguye. Imbaraga zo hejuru zo kwishyurwa byihuse zishobora kugera kuri 350kW cyangwa ndetse na 480kW, kandi igihe cyihuta cyo kwishyurwa giteganijwe kugabanuka kugeza munsi yiminota 30, kandi mugihe kizaza gishobora guhagarikwa kugeza munsi yiminota icumi.
