Incamake y'uburyo imodoka nshya ikoresha ingufu zisharija

Ibipimo bya bateri

1.1 Ingufu za batiri

Igice cy'ingufu za batiri ni kilowati-isaha (kWh), izwi kandi nka "degree". 1kWh bisobanura "ingufu zikoreshwa n'igikoresho cy'amashanyarazi gifite ingufu za kilowati 1 mu isaha imwe." Kugira ngo byorohe gusobanukirwa, iyi nkuru rusange ikoresha cyane cyane "degree" kugira ngo igaragaze. Abasomyi bakeneye kumenya gusa ko ari igice cy'ingufu z'amashanyarazi kandi ntibagomba gucengera ibisobanuro byacyo.

[Urugero] Ubushobozi bwa batiri z'imodoka na SUV zifite aho zikura uburebure bwa kilometero 500 ni dogere 60 na dogere 70. Ubu imodoka zikoresha amashanyarazi zikozwe mu buryo bunini zishobora gushyirwamo batiri zifite ubushobozi ntarengwa bwa 150 kwh n'uburebure bugera kuri kilometero 1.000.

Hari icyapa cy'izina kirimo amakuru y'ikinyabiziga ku muryango w'iburyo (cyangwa urugi rw'inyuma rw'iburyo) rw'ikinyabiziga gishya gifite ingufu. Ingano ya batiri ibarwa hakoreshejwe voltage ifite agaciro × ubushobozi buhanitse / 1000. Ibisubizo byabazwe bishobora kuba bitandukanye gato n'agaciro kemewe k'ikigo cy'imodoka.

1.2 SOC

SOC ni incamake ya "Leta y'ikirego", bivuga imiterere y'umuriro wa bateri, ni ukuvuga imbaraga za bateri zisigaye, ubusanzwe zigaragazwa nk'ijanisha."

1.3 Ubwoko bwa bateri

Inyinshi mu modoka nshya zikoresha ingufu ku isoko zikoresha bateri za lithium-ion, zishobora kugabanywamo bateri za lithium iron phosphate na bateri za ternary lithium.

Muri byo, hari ibimenyetso bibiri byihariye byerekana "ubudahinduka" bwa bateri za lithium iron phosphate. Icya mbere, ecran ya SOC ntabwo ari yo: urugero, umwanditsi aherutse guhura na Xpeng P5, yafashe iminota 50 kugira ngo ishyurwe kuva kuri 20% kugeza kuri 99%, mu gihe ishyuzwa kuva kuri 99% kugeza kuri Byatwaye iminota 30 kugira ngo igere kuri 100%, ibi bikaba bigaragara ko ari ikibazo kuri ecran ya SOC; icya kabiri, umuvuduko wo kugabanya ingufu ntungana (nanone bibaho cyane cyane iyo ishyuwe yuzuye): imodoka zimwe na zimwe nta mpinduka zigaragaza mu buzima bwa bateri nyuma yo gutwara kilometero 10 nyuma yo gushyuzwa yuzuye, mu gihe izindi modoka zitabifite. Uburambe bwa bateri bwagabanutse bukagera kuri kilometero 5 nyuma y'intambwe nke gusa. Kubwibyo, bateri za lithium iron phosphate zigomba gushyuzwa yuzuye rimwe mu cyumweru kugira ngo hakosorwe ubudahinduka bw'uturemangingo.

Ibinyuranye n'ibyo, bitewe n'imiterere y'ibikoresho, bateri za ternary lithium ntizikwiriye guparika imodoka nyuma yo gusharijwa yuzuye (ariko zishobora gukomeza gutwara imodoka kugeza munsi ya 90% nyuma yo gusharijwa yuzuye).Byongeye kandi, ubwoko bwose bwa batiri, ntigomba gukoreshwa mu gihe batiri ari nkeya (SOC <20%), kandi ntigomba no gushyushwa mu bidukikije bikabije (ubushyuhe buri hejuru ya 30°C cyangwa munsi ya 0°C).

Dukurikije umuvuduko wo gusharija, uburyo bwo gusharija bushobora kugabanywamo gusharija byihuse n'uburyo bwo gusharija buhoro.

(1)Gushyushya vuba

Umuvuduko wo gusharija vuba muri rusange ni umuvuduko w'imikorere y'ibinyabiziga bikoresha amashanyarazi (akenshi hafi 360-400V). Mu ngufu nyinshi, umuvuduko w'amashanyarazi ushobora kugera kuri 200-250A, bingana na 70-100kW by'ingufu. Hari ubwoko bumwe na bumwe bufite aho bugurishiriza bushobora kugera kuri 150kW binyuze mu muvuduko mwinshi. Imodoka nyinshi zishobora gusharija kuva kuri 30% kugeza kuri 80% mu gihe cy'iminota 30.

Urugero: Dufashe imodoka ifite ubushobozi bwa batiri ya dogere 60 (ifite intera ya kilometero 500) nk'urugero, gusharija vuba (ingufu za 60kW) bishoborashyira umuriro kuri batiriubuzima bwa kilometero 250 mu gice cy'isaha (ingufu nyinshi)
