Pfupiso yekuchaja mota itsva yemagetsi

Maparamita ebhatiri

1.1 Simba rebhatiri

Chikamu chesimba rebhatiri chinonzi kilowatt-awa (kWh), chinozivikanwawo se "degree". 1kWh zvinoreva "simba rinoshandiswa nemudziyo wemagetsi une simba rekilowatt imwe kweawa imwe." Kuti zvive nyore kunzwisisa, nhoroondo iyi yeruzhinji inonyanya kushandisa "degree" kuitsanangura. Vaverengi vanongoda kuziva kuti chikamu chesimba remagetsi uye havafanirwe kunyura muzvinoreva.

[Muenzaniso] Kugona kwemabhatiri emota neSUV dzine daro remakiromita mazana mashanu (500km) kuri pamadhigirii makumi matanhatu (60 degrees) uye makumi manomwe (70 degrees) zvichiteerana. Parizvino mota dzemagetsi dzakagadzirwa nemagetsi dzakawanda dzinogona kunge dziine mabhatiri ane daro repamusoro re150 kwh uye daro repamusoro rekutyaira rinosvika chiuru (1,000km).

Pane zita rine ruzivo rwemotokari pamusuwo wekurudyi (kana musuwo wekumashure wekurudyi) wemotokari itsva ine simba. Dhigirii rebhatiri rinoverengerwa uchishandisa voltage yakayerwa × kugona kwakayerwa/1000. Mhedzisiro yakayerwa inogona kusiyana zvishoma nemutengo wepamutemo wekambani yemotokari.

1.2 SOC

SOC ipfupiso yeshoko rekuti “Nyika yekutongwa", zvinoreva mamiriro ekuchaja kwebhatiri, kureva simba rebhatiri rasara, rinowanzo ratidzwa sechikamu.

1.3 Rudzi rwebhatiri

Mota zhinji dzemagetsi dziri pamusika dzinoshandisa mabhatiri e lithium-ion, ayo anogona kukamurwa kuita mabhatiri e lithium iron phosphate uye mabhatiri e ternary lithium.

Pakati pazvo, pane zviratidzo zviviri chaizvo zve "kusagadzikana kwakashata" kwemabhatiri e lithium iron phosphate. Chekutanga, kuratidzwa kweSOC hakuna kururama: semuenzaniso, munyori achangobva kuona Xpeng P5, iyo yakatora maminetsi makumi mashanu kuti ichajiswe kubva pa20% kusvika pa99%, ukuwo ichichajiswa kubva pa99% kusvika paZvakatora maminetsi makumi matatu kuti isvike pa100%, izvo zviri pachena kuti idambudziko neSOC display; chechipiri, kumhanya kwemagetsi hakuenzaniswi (kunonyanya kuitikawo kana chajiswa zvizere): dzimwe mota hadziratidzi shanduko muhupenyu hwebhatiri mushure mekutyaira 10km mushure mekuchajiswa zvizere, nepo dzimwe mota dzisingachaji. Hupenyu hwebhatiri hwakaderera kusvika pa5km mushure mematanho mashoma chete. Nokudaro, mabhatiri e lithium iron phosphate anofanira kuchajiswa zvizere kamwe chete pasvondo kugadzirisa kugadzikana kwemasero.

Kusiyana neizvi, nekuda kwemhando yezvinhu zvacho, mabhatiri e-ternary lithium haana kukodzera kupaka mota mushure mekunge anyatsochajwa (asi anogona kuramba achityaira kusvika pasi pe90% mushure mekunge anyatsochajwa).Pamusoro pezvo, zvisinei nekuti bhatiri rerudzii, harifanirwe kufambiswa kana bhatiri rakaderera (SOC <20%), uye harifanirwe kuchajwa munzvimbo dzakanyanya (tembiricha dziri pamusoro pe30°C kana pasi pe0°C).

Zvichienderana nekumhanya kwekuchaja, nzira dzekuchaja dzinogona kukamurwa kuva dzekuchaja nekukurumidza uye dzekuchaja zvishoma nezvishoma.

(1)Kuchaja nekukurumidza

Voltage yekuchaja nekukurumidza inowanzo kuve voltage inoshanda yemotokari dzemagetsi (kazhinji dzinenge 360-400V). Mune simba rakawanda, simba remagetsi rinogona kusvika 200-250A, zvichienderana ne70-100kW yesimba. Mamwe mamodheru ane nzvimbo yekuchaja senzvimbo yavo yekutengesa anogona kusvika 150kW kuburikidza nevoltage yakakwira. Mota zhinji dzinogona kuchaja kubva pa30% kusvika 80% muhafu yeawa.

[Muenzaniso] Kana tikatora mota ine bhatiri remadhigirii makumi matanhatu (rine daro rinosvika makiromita mazana mashanu) semuenzaniso, inogona kuchaja nekukurumidza (simba re60kW).charger bhatirihupenyu hwemakiromita mazana maviri nemakumi mashanu (250km) muhafu yeawa (simba rakawanda)
