-Ngati mukufuna kuyitanitsa mwachangu galimoto yanu yamagetsi, simungapite molakwika ndi ukadaulo wapamwamba kwambiri, wapamwamba kwambiri wamakono opangira milu

Ukadaulo wapamwamba wamakono komanso wokwera kwambiri

Pamene mitundu ikuwonjezeka pang'onopang'ono, pali zovuta monga kufupikitsa nthawi yolipiritsa ndi kuchepetsa mtengo wa umwini, ndipo ntchito yoyamba ndiyo kukhathamiritsa kukula kwa gawoli kuti mukwaniritse kukweza mphamvu. Popeza mphamvu yakulipira mulumakamaka zimadalira mphamvu ya superposition ya gawo lolipiritsa, ndipo lili ndi malire ndi kuchuluka kwazinthu, malo apansi ndi mtengo wopanga, kungowonjezera kuchuluka kwa ma module sikulinso njira yabwino kwambiri. Chifukwa chake, momwe mungakulitsire mphamvu ya gawo limodzi popanda kuwonjezera voliyumu yowonjezera yakhala vuto laukadaulo lomweopangira ma modulekufunika kogonjetsa mwachangu.

Zida zolipirira DCimakwanitsa kuthamangitsa mwachangu kudzera muukadaulo wamakono komanso wothamanga kwambiri. Ndi kuwonjezeka kwapang'onopang'ono kwa voteji ndi mphamvu, izi zimayika patsogolo zofunikira zowonjezereka kuti zigwire ntchito yokhazikika, kutentha kwachangu komanso kusinthika kwa gawo loyendetsa, zomwe mosakayikira zimakhazikitsa zovuta zamakono zopangira ma module opanga.

Poyang'anizana ndi kufunikira kwa msika kwa kuthamanga kwamphamvu kwambiri, opanga ma module othamangitsa amayenera kupitiliza kukonza ndi kukweza ukadaulo woyambira ndikumanga zotchinga zawo zaukadaulo. Ichi chidzakhala chinsinsi champikisano wamsika wam'tsogolo, pokhapokha podziwa luso lamakono, kuti mukhale osagonjetseka pampikisano woopsa wa msika.

1) Njira yamakono: mlingo wa kukwezedwa ndi wotsika, ndipo zofunikira zoyendetsera kutentha ndizokwera. Malinga ndi lamulo la Joule (chilinganizo cha Q = I2Rt), kuwonjezeka kwamakono kudzawonjezera kwambiri kutentha pa nthawi yolipiritsa, yomwe ili ndi zofunikira zazikulu zowonongeka kwa kutentha, monga njira yothetsera vutoli ya Tesla, yomwe V3 supercharging mulu ili ndi ntchito yapamwamba yoposa 600A, yomwe imafuna makina opangira mawaya ochulukirapo, omwe amafunikira nthawi yotentha, ndipo amatha kukwaniritsa zofunikira pa nthawi yomweyo. Kuthamanga kwakukulu kwa 250kW mu 5% -27% SOC, ndipo kulipira koyenera sikukuphimbidwa mokwanira. Pakalipano, opanga magalimoto apanyumba sanasinthe kwambiri makonda pa chiwembu chowotcha kutentha, ndimilu yothamanga kwambirikudalira kwambiri machitidwe odzipangira okha, zomwe zimapangitsa kuti pakhale ndalama zambiri zotsatsa.

2) Njira yothamanga kwambiri: Ndi njira yomwe imagwiritsidwa ntchito kwambiri ndi opanga magalimoto, omwe amatha kuganizira za ubwino wochepetsera mphamvu, kukonza moyo wa batri, kuchepetsa kulemera, ndi kusunga malo. Pakalipano, malire ndi mphamvu yamagetsi yamagetsi yamagetsi a silicon-based IGBT magetsi, njira yothamangitsira mofulumira yomwe imatengedwa ndi makampani agalimoto ndi nsanja ya 400V yothamanga kwambiri, ndiko kuti, mphamvu yowonjezera ya 100kW ikhoza kupindula ndi 250A (100kW mphamvu ikhoza kulipiritsa kwa 10km pafupifupi 100). Chiyambireni kukhazikitsidwa kwa nsanja ya Porsche's 800V high-voltage (kupeza mphamvu za 300KW ndikuchepetsa theka la ma waya okwera kwambiri), makampani akuluakulu amagalimoto ayamba kufufuza ndikuyika nsanja ya 800V yothamanga kwambiri. Poyerekeza ndi nsanja ya 400V, nsanja yamagetsi ya 800V ili ndi kachipangizo kakang'ono kogwiritsa ntchito, komwe kumasunga kuchuluka kwa ma waya, kumachepetsa kutayika kwamkati kwa dera, komanso kumathandizira kachulukidwe wamagetsi ndi mphamvu zamagetsi pobisalira.

Pakali pano, nthawi zonse mphamvu linanena bungwe voteji osiyanasiyana gawo lalikulu 40kW mu makampani ndi 300Vdc ~ 1000Vdc, amene n'zogwirizana ndi kulipiritsa zosowa panopa 400V nsanja magalimoto onyamula, 750V mabasi ndi tsogolo 800V-1000V mkulu-voteji nsanja magalimoto; Kutulutsa kwamagetsi kwa gawo la 40kW la Infineon, Telai ndi Shenghong kumatha kufika 50Vdc ~ 1000Vdc, poganizira zofunikira zolipirira magalimoto otsika. Pankhani ya magwiridwe antchito onse a gawoli, ma module a 40kW apamwamba kwambiri aMphamvu ya BeiHaigwiritsani ntchito zida zamagetsi za SIC, ndipo magwiridwe antchito apamwamba amatha kufikira 97%, omwe ndi apamwamba kuposa kuchuluka kwamakampani.
