Ibipimo bya Batiri

1.1 Ingufu za Batiri

Igice cyingufu za batiri ni kilowatt-isaha (kilowat), izwi kandi nka "dogere". 1kWh bisobanura "ingufu zikoreshwa nigikoresho cyamashanyarazi gifite ingufu za kilowatt 1 kumasaha imwe." Kugirango byoroshye kumvikana, iyi konte rusange ikoresha "impamyabumenyi" kugirango igaragaze. Basomyi bakeneye kumenya gusa ko ari igice cyingufu zamashanyarazi kandi ntibakeneye gucengera mubisobanuro byacyo.

[Urugero] Ubushobozi bwa bateri yimodoka na SUV zifite intera ya kilometero 500 ni hafi dogere 60 na dogere 70. Kugeza ubu ibinyabiziga byamashanyarazi byakozwe cyane birashobora kuba bifite bateri zifite ubushobozi ntarengwa bwa kwh 150 hamwe nubushakashatsi bwo gutwara ibintu bugera kuri 1.000 km.

Hano hari icyapa cyanditseho amakuru yikinyabiziga kumuryango wiburyo (cyangwa umuryango winyuma winyuma) yikinyabiziga gishya. Impamyabumenyi ya batiri ibarwa ukoresheje voltage yagenwe capacity ubushobozi bwagenwe / 1000. Ibisubizo bibarwa birashobora gutandukana gato nagaciro kemewe nisosiyete yimodoka.

1.2 SOC

SOC ni impfunyapfunyo ya “Leta ishinzwe“, Bisobanura uko bateri imeze, ni ukuvuga ingufu za batiri zisigaye, ubusanzwe zigaragazwa nkijanisha.

1.3 Ubwoko bwa Bateri

Umubare munini wimodoka nshya zingufu kumasoko zikoresha bateri ya lithium-ion, ishobora kugabanywamo bateri ya fosifate ya lithium fer na batiri ya lithium.

Muri byo, hari ibintu bibiri byihariye byerekana “kutamenya neza” kwa batiri ya lithium fer fosifate. Ubwa mbere, kwerekana SOC ntabwo aribyo: kurugero, umwanditsi aherutse kwibonera Xpeng P5, byafashe iminota 50 yo kwishyuza kuva 20% kugeza 99%, mugihe kwishyuza kuva 99% kugeza Byatwaye iminota 30 kugirango ugere 100%, biragaragara ko bigaragara ikibazo hamwe no kwerekana SOC; icya kabiri, umuvuduko wamashanyarazi nturinganiza (nanone bibaho cyane cyane iyo byuzuye): imodoka zimwe zerekana ko nta gihinduka mubuzima bwa bateri nyuma yo gutwara kilometero 10 nyuma yo kwishyurwa byuzuye, mugihe imodoka zimwe zitabikora. Ubuzima bwa bateri bwaragabanutse kugera kuri 5km nyuma yintambwe nkeya. Kubwibyo, bateri ya lithium fer fosifate igomba kwishyurwa byuzuye rimwe mucyumweru kugirango ikosore ingirabuzimafatizo.

Ibinyuranye na byo, bitewe n'imiterere y'ibikoresho, bateri ya lithium ya ternary ntabwo ikwiriye guhagarara nyuma yo kwishyurwa byuzuye (ariko irashobora gukomeza gutwara kugeza munsi ya 90% ako kanya nyuma yo kwishyurwa byuzuye).Byongeye kandi, uko bateri yaba imeze kose, ntigomba gutwarwa mubihe bito bya batiri (SOC <20%), ntanubwo igomba kwishyurwa mubidukikije bikabije (ubushyuhe buri hejuru ya 30 ° C cyangwa munsi ya 0 ° C).

Ukurikije umuvuduko wo kwishyuza, uburyo bwo kwishyuza burashobora kugabanywa muburyo bwo kwishyuza byihuse no gutinda buhoro.

(1)Kwishyuza byihuse

Umuvuduko wamashanyarazi wumuriro wihuse mubisanzwe ni voltage ikora yimodoka yamashanyarazi (cyane cyane 360-400V). Mumurongo mwinshi w'amashanyarazi, ikigezweho gishobora kugera kuri 200-250A, bihuye na 70-100kW yingufu. Moderi zimwe hamwe no kwishyuza nkaho kugurisha bishobora kugera kuri 150kW binyuze mumashanyarazi menshi. hejuru. Imodoka nyinshi zirashobora kwishyurwa kuva 30% kugeza 80% mugice cyisaha.

[Urugero] Gufata imodoka ifite ubushobozi bwa bateri ya dogere 60 (ifite intera igera kuri 500km) nkurugero, kwishyuza byihuse (power 60kW) birashoborakwishyuza bateriubuzima bwa 250km mu gice cy'isaha (ingufu nyinshi)
