–Ngati mukufuna kuyitanitsa mwachangu galimoto yanu yamagetsi, simungalakwitse ndi ukadaulo wamagetsi amphamvu komanso wamphamvu woyitanitsa ma piles.

Ukadaulo wamagetsi amphamvu komanso okwera

Pamene kuchuluka kwa magetsi kukukwera pang'onopang'ono, pamakhala zovuta monga kufupikitsa nthawi yochaja ndikuchepetsa mtengo wa umwini, ndipo ntchito yoyamba ndikukonza kukula kwa module kuti pakhale kukweza mphamvu. Popeza mphamvu yamulu wolipiritsaMakamaka zimadalira mphamvu ya gawo lochaja, ndipo zimachepetsedwa ndi kuchuluka kwa chinthu, malo osungira pansi ndi mtengo wopangira, kungowonjezera kuchuluka kwa ma module sikulinso yankho labwino kwambiri. Chifukwa chake, momwe mungawonjezere mphamvu ya gawo limodzi popanda kuwonjezera voliyumu yowonjezera yakhala vuto laukadaulo lomweopanga gawo lolipiritsakufunika kugonjetsa mwachangu.

Zipangizo zolipirira za DCimapeza mphamvu yabwino kwambiri yochaja mwachangu kudzera muukadaulo wamagetsi amphamvu komanso amphamvu. Ndi kuwonjezeka pang'onopang'ono kwa magetsi ndi mphamvu, izi zimapangitsa kuti pakhale zofunikira kwambiri kuti pakhale ntchito yokhazikika, kuyeretsa bwino kutentha komanso kusintha bwino kwa gawo lochaja, zomwe mosakayikira zimayambitsa zovuta zazikulu zaukadaulo kwa opanga ma module ochaja.

Poyang'anizana ndi kufunikira kwa msika kwa mphamvu yayikulu yochaja mwachangu, opanga ma module ochaja ayenera kupitiliza kupanga zatsopano ndikukweza ukadaulo woyambira ndikumanga zopinga zawo zazikulu zaukadaulo. Izi zidzakhala chinsinsi cha mpikisano wamsika wamtsogolo, pokhapokha podziwa bwino ukadaulo woyambira, kuti asagonjetsedwe pampikisano waukulu wamsika.

1) Njira yamagetsi amphamvu: mlingo wokwezedwa ndi wotsika, ndipo zofunikira pakuwongolera kutentha ndizokwera. Malinga ndi lamulo la Joule (formula Q=I2Rt), kuwonjezeka kwa magetsi kudzawonjezera kutentha kwambiri panthawi yochaja, komwe kuli ndi zofunikira kwambiri pakutha kutentha, monga njira yochaja mwachangu ya Tesla, yomwe mulu wake wa V3 supercharging uli ndi mphamvu yogwira ntchito yoposa 600A, yomwe imafuna waya wolimba, ndipo nthawi yomweyo, ili ndi zofunikira kwambiri paukadaulo wotha kutentha, ndipo imatha kupeza mphamvu yayikulu yochaja ya 250kW mu 5%-27% SOC, ndipo kuchaja koyenera sikukuphimbidwa mokwanira. Pakadali pano, opanga magalimoto am'nyumba sanapange kusintha kwakukulu pa njira yotha kutentha, ndipomilu yochaja yamphamvu kwambirikudalira kwambiri machitidwe odzipangira okha, zomwe zimapangitsa kuti pakhale ndalama zambiri zotsatsira.

2) Njira yamagetsi amphamvu: Ndi njira yomwe imagwiritsidwa ntchito kwambiri ndi opanga magalimoto, yomwe ingaganizire zabwino zochepetsera kugwiritsa ntchito mphamvu, kukonza moyo wa batri, kuchepetsa kulemera, ndikusunga malo. Pakadali pano, chifukwa cha mphamvu yamagetsi yokhazikika ya zida zamagetsi za IGBT zochokera ku silicon, njira yolipirira mwachangu yomwe imagwiritsidwa ntchito ndi makampani oyendetsa magalimoto ndi nsanja yamagetsi amphamvu ya 400V, kutanthauza kuti, mphamvu yolipirira ya 100kW ikhoza kupezeka ndi mphamvu yamagetsi ya 250A (mphamvu ya 100kW ikhoza kulipiridwa kwa mphindi 10 kwa pafupifupi 100km). Kuyambira pomwe nsanja yamagetsi yapamwamba ya Porsche ya 800V idakhazikitsidwa (yopeza mphamvu ya 300KW ndikuchepetsa theka la chingwe chamagetsi chamagetsi amphamvu), makampani akuluakulu amagalimoto ayamba kufufuza ndikuyika nsanja yamagetsi yapamwamba ya 800V. Poyerekeza ndi nsanja ya 400V, nsanja yamagetsi ya 800V ili ndi mphamvu yocheperako yogwirira ntchito, yomwe imasunga kuchuluka kwa chingwe chamagetsi, imachepetsa kutayika kwamkati kwa dera, ndikuwonjezera kuchuluka kwa mphamvu ndi kugwiritsa ntchito bwino mphamvu zomwe zimabisika.

Pakadali pano, mphamvu yotulutsa mphamvu yokhazikika ya gawo lalikulu la 40kW mumakampani ndi 300Vdc ~ 1000Vdc, zomwe zimagwirizana ndi zosowa zochajira zamagalimoto apaulendo a 400V omwe alipo, mabasi a 750V ndi magalimoto apamwamba a 800V-1000V amtsogolo; Mphamvu yotulutsa mphamvu ya gawo la 40kW la Infineon, Telai ndi Shenghong imatha kufika 50Vdc ~ 1000Vdc, poganizira zosowa zochajira zamagalimoto otsika mphamvu. Ponena za magwiridwe antchito onse a gawoli, ma module amphamvu a 40kW aMphamvu ya BeiHaiGwiritsani ntchito zida zamagetsi za SIC, ndipo mphamvu yapamwamba kwambiri imatha kufika pa 97%, zomwe ndi zapamwamba kuposa avareji yamakampani.
