Kodi ubwino wa nsanja ya 800V yothamanga kwambiri yomwe aliyense amawotcha ndi yotani, ndipo ingayimire tsogolo la tramu?

Nkhawa zambiri ndiye cholepheretsa chachikulu pamsika wamagalimoto amagetsi, ndipo tanthawuzo la kusanthula mosamalitsa kwa nkhawa zosiyanasiyana ndi "kupirira kwakanthawi" komanso "kulipira pang'onopang'ono". Pakalipano, kuwonjezera pa moyo wa batri, n'zovuta kupita patsogolo, kotero "charge charge" ndi "supercharge" ndizo zomwe zimayang'ana pamakono amakampani osiyanasiyana agalimoto. Choncho a800V mkulu mphamvunsanja idayamba kukhalapo.

Kwa ogula wamba, 800V high-voltage nsanja yolimbikitsidwa ndi makampani amagalimoto ndi nthawi yaukadaulo, koma monga ukadaulo wofunikira m'tsogolomu, umagwirizananso ndi zomwe ogula amakumana nazo pamagalimoto, ndipo tiyenera kumvetsetsa bwino zaukadaulo watsopanowu. . Choncho, pepala ili lidzafufuza mozama nsanja ya 800V yothamanga kwambiri kuchokera kuzinthu zosiyanasiyana monga mfundo, zofuna, chitukuko ndi kutera.

Chifukwa chiyani mukufunikira nsanja ya 800V?

M'zaka ziwiri zapitazi, ndi kuwonjezeka kwapang'onopang'ono kwa magalimoto amagetsi, chiwerengero cha milu yolipiritsa chakwera nthawi imodzi, koma chiŵerengero cha mulu sichinachepe. Pofika kumapeto kwa 2020, "galimoto-mulu ratio" yamagalimoto atsopano amagetsi apanyumba ndi 2.9: 1 (chiwerengero cha magalimoto ndi 4.92 miliyoni ndi milu yolipiritsa ndi 1.681 miliyoni). Mu 2021, chiŵerengero cha galimoto ndi mulu chidzakhala 3: 1, chomwe sichidzachepa koma chidzawonjezeka. Zotsatira zake ndikuti nthawi ya pamzere ndi yayitali kuposa nthawi yolipirira.

Ndiye pankhani ya kuchuluka kwa milu yolipiritsa sikungapitirire, kuti muchepetse nthawi yamilu yolipiritsa, ukadaulo wothamangitsa mwachangu ndikofunikira kwambiri.

Kuwonjezeka kwa liwiro la kuthamanga kumatha kumveka bwino ngati kuwonjezeka kwa mphamvu yowonjezera, ndiko kuti, P = U · I mu P (P: mphamvu yowonjezera, U: magetsi othamanga, I: kuyendetsa magetsi). Chifukwa chake, ngati mukufuna kuwonjezera mphamvu yolipiritsa, sungani voliyumu imodzi kapena yamakono yosasinthika, kuwonjezera mphamvu yamagetsi kapena yapano kumatha kuwongolera mphamvu yolipirira. Kukhazikitsidwa kwa nsanja yamagetsi apamwamba ndikuwongolera kuyendetsa bwino kwagalimoto ndikuzindikira kuthamangitsanso kwagalimoto kumapeto.

Pulogalamu ya 800Vkwa magalimoto amagetsi ndiye chisankho chachikulu pakulipira mwachangu. Kwa mabatire amphamvu, kuthamangitsa mwachangu ndikofunikira kuti muwonjezere kuchuluka kwa ma cell, komwe kumatchedwanso kuchuluka kwacharge; Pakalipano, makampani ambiri amagalimoto ali mu dongosolo la makilomita 1000 oyendetsa galimoto, koma teknoloji yamakono ya batri, ngakhale itapangidwa kukhala mabatire olimba, imafunikiranso paketi ya batri yoposa 100kWh, yomwe idzatsogolera kuwonjezeka kwa chiwerengero cha maselo, ngati nsanja yaikulu ya 400V ikupitiriza kugwiritsidwa ntchito, chiwerengero cha maselo ofanana chikuwonjezeka, zomwe zimabweretsa kuwonjezeka kwa mabasi. Zimabweretsa zovuta zazikulu pamatchulidwe a waya wamkuwa ndi chubu cha chitoliro cha kutentha.

Choncho, m'pofunika kusintha ndondomeko yofanana ya maselo a batri mu paketi ya batri, kuchepetsa kufanana ndi kuonjezera mndandanda, kuti muwonjezere ndalama zomwe mumalipira ndikusunga nsanja panopa pamlingo woyenera. Komabe, kuchuluka kwa mndandanda kuchulukirachulukira, voliyumu yomaliza ya batri idzawonjezeka. Mphamvu yamagetsi yofunikira pa paketi ya batire ya 100kWh kuti ifike ku 4C mwachangu ndi pafupifupi 800V. Kuti zigwirizane ndi kuthamangitsa mwachangu kwamitundu yonse yamitundu, zomangamanga zamagetsi za 800V ndiye chisankho chabwino kwambiri.
