Vuto la dongosolo la 800V: mulu wolipiritsa pamakina opangira

800V Kulipira mulu "Zoyambira Zoyambira"

Nkhaniyi makamaka ikukamba za zofunika zina zoyambirira za 800Vkulipiritsa milu, choyamba tiyeni tione mfundo ya kulipiritsa: Pamene nsonga yolipiritsa ikugwirizana ndi mapeto a galimoto, mulu wothamangitsira udzapereka (1) mphamvu ya DC yothandizira magetsi otsika mpaka kumapeto kwa galimoto kuti atsegule BMS yomangidwa (kasamalidwe ka batri) ya galimoto yamagetsi Pambuyo poyambitsa, (2) gwirizanitsani kusinthanitsa kwa galimoto mpaka kumapeto kwa chiwongoladzanja chamagetsi, mwachitsanzo, kuthamangitsidwa kwa galimoto yamagetsi. kutha kwagalimoto ndi mphamvu yayikulu yotulutsa mulu, mbali ziwirizo zitafananizidwa bwino, BMS (kasamalidwe ka batri) yomaliza yamagalimoto imatumiza chidziwitso chofuna mphamvu kwaev charging station, ndimulu wothamangitsa galimoto yamagetsiidzasintha voteji yakeyake ndi yapano malinga ndi chidziwitsochi, ndikuyamba kulipiritsa galimotoyo, yomwe ndi mfundo yayikulu yakugwirizana kwacharge, ndipo tiyenera kudziŵa kaye.

Kuthamanga kwa 800V: "kuwonjezera mphamvu kapena magetsi"

Mwachidziwitso, ngati tikufuna kupereka mphamvu yolipirira kuti muchepetse nthawi yolipira, nthawi zambiri pali njira ziwiri: mwina mumawonjezera batri kapena kuwonjezera mphamvu; Malinga ndi W=Pt, ngati mphamvu yolipiritsa ichulukitsidwa kawiri, nthawi yolipiritsa mwachilengedwe idzakhala ndi theka; Malingana ndi P = UI, ngati magetsi kapena magetsi akuwirikiza kawiri, mphamvu yowonjezera imatha kuwirikiza kawiri, yomwe yatchulidwa mobwerezabwereza ndipo imatengedwa ngati yanzeru.

Ngati panopa ndi yaikulu, padzakhala mavuto awiri, zazikulu zamakono, zazikulu ndi zazikulu chingwe chomwe chimafuna panopa, chomwe chidzawonjezera waya wa waya ndi kulemera kwake, kuonjezera mtengo, ndipo sikoyenera kuti ogwira ntchito azigwira ntchito; Kuphatikiza apo, malinga ndi Q=I²Rt, ngati magetsi ali apamwamba, kutayika kwa mphamvu kumakhala kokulirapo, ndipo kutayika kumawonekera mu mawonekedwe a kutentha, komwe kumawonjezeranso kupanikizika kwa kayendetsedwe ka kutentha, kotero palibe kukayikira kuti sikoyenera kuonjezera mphamvu yolipiritsa powonjezera mphamvu yamagetsi mosalekeza, kaya ikulipira kapena galimoto yoyendetsa galimoto.

Poyerekeza ndi kulipiritsa kwanthawi yayitali,kuthamanga kwamagetsi okwera kwambirizimapanga kutentha pang'ono ndi kutayika kochepa, ndipo pafupifupi makampani oyendetsa galimoto atengera njira yowonjezera voteji, pankhani ya kuthamanga kwamagetsi othamanga kwambiri, nthawi yothamanga imatha kufupikitsidwa ndi 50%, ndipo kuwonjezeka kwa voteji kungathenso kuwonjezera mphamvu yowonjezera kuchokera ku 120KW mpaka 480KW.

Kulipiritsa kwa 800V: "Zotsatira zamatenthedwe zomwe zimagwirizana ndi magetsi komanso zamakono"

Koma kaya ikuwonjezera magetsi kapena kuwonjezereka kwamakono, choyamba, ndi kuwonjezeka kwa mphamvu yanu yolipiritsa, kutentha kwanu kudzawoneka, koma mawonetseredwe a kutentha kwa kuwonjezeka kwa voliyumu ndi kuonjezera panopa ndi zosiyana. Komabe, yoyambayo ndiyabwino poyerekeza.

Chifukwa cha kukana kutsika komwe kumakumana ndi pano podutsa pa kondakitala, njira yowonjezeretsa voteji imachepetsa kukula kwa chingwe, ndipo kutentha komwe kumayenera kutayidwa kumakhala kochepa, ndipo pomwe magetsi akuchulukirachulukira, kuwonjezereka kwa gawo lomwe lili ndi gawo lomwe lilipo kumabweretsa kukula kwakunja ndi chingwe chokulirapo, ndipo kutentha kumawonjezeka pang'onopang'ono ndikuwonjezera kwa batire, yomwe imakhala pachiwopsezo chokulirapo, chomwe chimakhala chowopsa kwambiri.

Kulipiritsa kwa 800V: "Zovuta zina zaposachedwa ndi milu yolipiritsa"

Kuthamangitsa mwachangu kwa 800V kumakhalanso ndi zofunikira zina kumapeto kwa mulu:

Ngati kuchokera ku thupi, ndi kuwonjezeka kwa voteji, kukula kwa mapangidwe a zipangizo zogwirizana ziyenera kuwonjezeka, mwachitsanzo, malinga ndi mlingo wa kuipitsidwa kwa IEC60664 ndi 2 ndi mtunda wa gulu la zinthu zotetezera ndi 1, mtunda wa chipangizo chokwera kwambiri chiyenera kukhala kuchokera ku 2mm mpaka 4mm, ndipo zofunikira zomwezo zotchinjiriza zomwezo zidzawonjezekanso, zomwe zimafunikanso kukonzanso mtunda, zomwe zimafunikanso kuti zisinthe. kamangidwe poyerekeza ndi kamangidwe ka voteji yapita dongosolo, kuphatikizapo zolumikizira, mipiringidzo mkuwa, zolumikizira, etc. Komanso, kuwonjezeka voteji kudzachititsanso apamwamba zofunika kuzimitsa arc, ndipo m'pofunika kuonjezera zofunika zipangizo zina monga fuse, mabokosi lophimba, zolumikizira, etc., zomwe zimagwiranso ntchito pa kapangidwe ka galimoto, zomwe zidzatchulidwa m'nkhani zotsatila.

Dongosolo lacharging lamphamvu kwambiri la 800V liyenera kuwonjezera makina oziziritsira amadzimadzi akunja monga tafotokozera pamwambapa, ndipo kuzirala kwachikhalidwe sikungakwaniritse zofunikira kaya kuzizira kapena kuzizira, komanso kasamalidwe ka matenthedwe.malo opangira magalimoto amagetsiMzere wa mfuti mpaka kumapeto kwa galimoto ndi wapamwamba kwambiri kuposa kale, ndi momwe mungachepetsere ndi kuwongolera kutentha kwa gawo ili la dongosolo kuchokera pa mlingo wa chipangizo ndi mlingo wa dongosolo ndilofunika kuwongolera ndi kuthetsedwa ndi kampani iliyonse m'tsogolomu; Kuonjezera apo, mbali iyi ya kutentha si kutentha kokha komwe kumabwera chifukwa cha kuchulukitsitsa, komanso kutentha komwe kumabwera ndi zipangizo zamagetsi zothamanga kwambiri, kotero momwe mungachitire nthawi yeniyeni yowunikira komanso yokhazikika, yogwira mtima komanso yotetezeka kuti mutenge kutentha ndikofunika kwambiri, zomwe sizongowonjezereka muzinthu, komanso kufufuza mwadongosolo, monga nthawi yeniyeni komanso kuyang'anitsitsa kutentha kwa kutentha.

Pakali pano, linanena bungwe voteji waDC yopangira milupa msika kwenikweni 400V, amene sangathe mwachindunji mlandu batire 800V mphamvu, kotero kulimbikitsa zina DCDC mankhwala chofunika kuukitsa 400V voteji kuti 800V, ndiyeno kulipira batire, chimene chimafuna mphamvu apamwamba ndi kusintha kwakukulu pafupipafupi, ndi gawo limene limagwiritsa ntchito silicon carbide m'malo IGBT chikhalidwe ndi kusankha panopa waukulu carbide canconbide ndi carconbide. kuchepetsa kutayika, koma mtengo wake ndi wokwera kwambiri, ndipo zofunikira za EMC ndizokweranso.

Kuti tifotokoze mwachidule. Kwenikweni, kuwonjezereka kwamagetsi kuyenera kukulitsidwa pamlingo wamakina ndi mulingo wa chipangizocho, kuphatikiza makina owongolera matenthedwe, makina oteteza ma charger, ndi zina zambiri, ndipo mulingo wa chipangizocho umaphatikizapo kukonza kwa zida zina zamaginito ndi zida zamagetsi.
