Mhedziso yekuchaja kwemotokari nyowani

Battery parameters

1.1 Battery simba

Iyo unit yebhatiri simba ndeye kilowatt-awa (kWh), inozivikanwawo se "degree". 1kWh zvinoreva "simba rinoshandiswa nechinhu chemagetsi chine simba re1 kilowatt kweawa imwe." Kuti zvive nyore kunzwisisa, iyi account yeruzhinji inonyanya kushandisa "dhigirii" kuiburitsa. Vaverengi vanongoda kuziva kuti iyuniti yesimba remagetsi uye haidi kunyura mune zvarinoreva.

[Muenzaniso] Mabhatiri emagetsi emota uye maSUV ane huwandu hwe500km angangoita 60 madhigirii uye 70 madhigirii zvichiteerana. Parizvino motokari dzemagetsi dzakagadzirwa nemhando dzakawanda dzinogona kuve nemabhatiri ane huwandu hwe150 kwh uye dhizaini yekutyaira inosvika 1,000km.

Pane nameplate ine ruzivo rwemotokari pamusuwo wekurudyi wekumberi (kana wekurudyi kumashure kwemusuwo) wemota nyowani ine simba. Dhigirii yebhatiri inoverengerwa nekushandisa yakayerwa voltage × yakayerwa kugona/1000. Mhedzisiro yakaverengerwa inogona kunge yakasiyana zvishoma kubva kune yepamutemo kukosha kwekambani yemotokari.

1.2 SOC

SOC ndiyo chidimbu che "State of charge", iyo inoreva mamiriro ebhatiri, kureva, simba rebhatiri rasara, rinowanzoratidzwa sechikamu.

1.3 Bhatiri mhando

Iyo yakawanda yemotokari nyowani dzemagetsi pamusika dzinoshandisa lithium-ion mabhatiri, ayo anogona kukamurwa kuita lithium iron phosphate mabhatiri uye ternary lithium mabhatiri.

Pakati pavo, pane zviratidzo zviviri zvakananga zve "hurombo hutsika" hwe lithium iron phosphate mabhatiri. Kutanga, iyo SOC kuratidzwa haina kururama: semuenzaniso, munyori achangobva kuona Xpeng P5, iyo yakatora maminitsi makumi mashanu kubhadharisa kubva pa20% kusvika 99%, ichichaja kubva ku99% kuenda Kwakatora maminetsi makumi matatu kusvika ku100%, izvo zviri pachena. dambudziko neSOC kuratidza; chechipiri, simba-pasi rinomhanya harina kuenzana (zvakare rinonyanya kuitika kana rakazara zvakakwana): dzimwe motokari dzinoratidza kusachinja kwehupenyu hwebheteri mushure mekutyaira 10km mushure mekubhadhara zvakakwana, asi dzimwe motokari dzisingaiti. Upenyu hwebhatiri hwakadonha kusvika ku5km mushure mematanho mashoma. Nokudaro, mabhatiri e-lithium iron phosphate anofanira kubhadharwa zvakakwana kamwe chete pavhiki kugadzirisa kuwirirana kwemasero.

Pane zvinopesana, nekuda kwechimiro chechinhu, ternary lithium mabhatiri haana kukodzera kupaka mushure mekuchajiswa zvakakwana (asi anogona kuramba achityaira kusvika pasi pe90% pakarepo mushure mekuchajiswa zvizere).Mukuwedzera, zvisinei kuti imhando ipi yebhatiri, haifaniri kutungamirirwa pasi pemamiriro ebheteri yakaderera (SOC <20%), uye haifaniri kubhadharwa munzvimbo dzakanyanyisa (kupisa kunopfuura 30 ° C kana pasi pe0 ° C).

Zvinoenderana nekumhanya kwekuchaja, nzira dzekuchaja dzinogona kukamurwa kuita kukurumidza kuchaja uye kunonoka kuchaja.

(1)Kuchaja nekukurumidza

Iyo yekuchaja vhezheni yekuchaja nekukurumidza kazhinji ivoltage inoshanda yemotokari dzemagetsi (kunyanya kutenderera 360-400V). Mune simba repamusoro, ikozvino inogona kusvika 200-250A, inoenderana ne70-100kW yesimba. Mamwe mamodheru ane kuchaja sezvo nzvimbo yavanotengesera inogona kusvika 150kW kuburikidza nehigh voltage. kumusoro. Mota zhinji dzinogona kuchaja kubva pa30% kusvika pa80% muhafu yeawa.

[Muenzaniso] Kutora mota ine bhatiri rinokwana madhigirii 60 (ine huwandu hwe500km) semuenzaniso, kukurumidza kuchaja (simba 60kW) inogonakuchaja bhatirihupenyu hwe250km muhafu yeawa (yakakwirira simba renji)
