He tirohanga whānui mō te utu waka hiko hou

Ngā tawhā pākahiko

1.1 Pūngao pākahiko

Ko te waeine o te pūngao pākahiko ko te kilowatt-haora (kWh), e mōhiotia ana ko te "tohu". Ko te tikanga o te 1kWh ko "te pūngao e pau ana i tētahi taputapu hiko he 1 kilowatt te kaha mō te kotahi hāora." Hei ngāwari ake te mārama, ko te tikanga o tēnei pūkete tūmatanui ko te "tohu" hei whakapuaki. Me mōhio noa ngā kaipānui he waeine o te pūngao hiko, ā, kāore e hiahiatia kia ruku hohonu ki tōna tikanga.

[Tauira] Ko te kaha o te pākahiko o ngā motuka me ngā SUV me te whānuitanga o te 500km he tata ki te 60 nekehanga me te 70 nekehanga. I tēnei wā, ka taea te whakamahi i ngā waka hiko parakore kua hangaia papatipu ki ngā pākahiko me te kaha mōrahi o te 150 kwh me te whānuitanga taraiwa arorau tae atu ki te 1,000km.

He papa ingoa kei te tatau o mua i te taha matau (te tatau o muri rānei i te taha matau) o tētahi waka hiko hou. Ka tatauhia te nui o te pākahiko mā te whakamahi i te ngaohiko whakatauranga × te kaha whakatauranga/1000. Tērā pea he rerekē te hua tatau mai i te uara mana o te kamupene waka.

1.2 SOC

Ko te SOC te whakarāpopototanga o "Te āhua o te kawenga", e pā ana ki te āhua o te utu o te pākahiko, arā, te toenga o te mana pākahiko, e whakaatuhia ana i te ōrau."

1.3 Momo pākahiko

Ko te nuinga o ngā waka hiko hou kei te mākete e whakamahi ana i ngā pākahiko lithium-ion, e taea te wehewehe ki ngā pākahiko lithium rino phosphate me ngā pākahiko lithium ternary.

I roto i ēnei, e rua ngā āhuatanga motuhake o te "koretake o te pumau" o ngā pākahiko lithium rino phosphate. Tuatahi, he hē te whakaaturanga SOC: hei tauira, i kite tata nei te kaituhi i te Xpeng P5, i roa te utu mai i te 20% ki te 99% mō te 50 meneti, i te wā e utu ana mai i te 99% ki te 30 meneti ka tae ki te 100%, he raruraru mārama tēnei ki te whakaaturanga SOC; tuarua, he koretake te tere whakaweto hiko (ka puta te nuinga ina utua katoatia): kāore ētahi waka e whakaatu i te huringa o te ora o te pākahiko i muri i te taraiwa 10km i muri i te utu katoa, ko ētahi waka kāore. I heke te ora o te pākahiko ki te 5km i muri i ētahi hikoinga noa iho. Nō reira, me utu katoa ngā pākahiko lithium rino phosphate kotahi i te wiki hei whakatika i te pumau o ngā pūtau.

I te ritenga kē, nā te āhua o te rauemi, kāore e pai ngā pākahiko lithium toru mō te tūnga waka i muri i te whakakī katoa (engari ka taea tonu e rātou te taraiwa ki raro iho i te 90% i muri tonu i te whakakī katoa).Hei tāpiritanga, ahakoa te momo pākahiko, kaua e whakahaerehia i raro i ngā āhuatanga pākahiko iti (SOC <20%), kaua hoki e utua i roto i ngā taiao tino kino (pāmahana neke atu i te 30°C, i raro iho rānei i te 0°C).

E ai ki te tere o te utu, ka taea te wehewehe i ngā tikanga utu ki te utu tere me te utu puhoi.

(1)Te utu tere

Ko te ngaohiko utu o te utu tere ko te ngaohiko mahi o ngā waka hiko (te nuinga o te wā tata ki te 360-400V). I te awhe mana teitei, ka taea e te iahiko te eke ki te 200-250A, e rite ana ki te 70-100kW o te mana. Ko ētahi tauira me te utu hei tohu hokohoko ka taea te eke ki te 150kW mā te ngaohiko teitei. i runga ake nei. Ka taea e te nuinga o ngā waka te utu mai i te 30% ki te 80% i roto i te hawhe haora.

[Tauira] Hei tauira, he waka he 60 nekehanga te kaha o te pākahiko (me te whānuitanga o te 500km), ka taea e te utu tere (mana 60kW) teutuhia he pākahikote roa o te haerenga 250km i roto i te hawhe haora (te whānuitanga mana teitei)
