Dulmarka ku dallaca gaadhiga tamarta cusub

Halbeegyada baytariyada

1.1 Tamarta baytariga

Unugga tamarta baytarigu waa kilowatt-saac (kWh), oo sidoo kale loo yaqaan "degree". 1kWh macneheedu waa "tamarta uu isticmaalo qalab koronto oo leh awood 1 kilowatt ah hal saac." Si loo fududeeyo fahamka, xisaabtan dadweynuhu waxay badi isticmaashaa "shahaadada" si ay u qeexdo. Akhristayaashu waxa ay u baahan yihiin oo kaliya in ay ogaadaan in ay tahay unug tamarta korantada ah oo aan u baahnayn in ay u dhuuxaan macnaheeda.

[Tusaale] Awooda baytariga baabuurta iyo SUV-yada leh masaafo dhan 500km waxay ku dhow yihiin 60 darajo iyo 70 darajo siday u kala horreeyaan. Hadda baabuurta saafiga ah ee la soo saaray ee tirada badan waxa lagu qalabayn karaa baytari leh awoodda ugu badan ee 150 kwh iyo cabbir wadista aragti ahaan ilaa 1,000km.

Waxa jira taariko ay ku qoran tahay macluumaadka gaadhiga albaabka hore ee midig (ama albaabka dambe ee midig) ee gaadhiga tamarta cusub. Heerka batteriga waxaa lagu xisaabiyaa iyadoo la isticmaalayo danab la qiimeeyay × awoodda lagu qiimeeyay/1000. Natiijada la xisaabiyay ayaa laga yaabaa inay ka yara duwanaato qiimaha rasmiga ah ee shirkadda baabuurta.

1.2 SOC

SOC waa soo gaabinta "Xaalada xilka", taas oo tixraacaysa xaaladda batteriga, taas oo ah, awoodda batteriga ee hadhay, oo badanaa lagu muujiyey boqolkiiba.

1.3 Nooca baytari

Inta badan baabuurta tamarta cusub ee suuqa ku jirta waxay isticmaalaan baytariyada lithium-ion, kuwaas oo loo qaybin karo baytariyada fosfateed ee lithium iyo baytariyada lithium ternary.

Waxaa ka mid ah, waxaa jira laba astaamood oo gaar ah oo ah "joogteynta liidata" ee baytariyada fosfateed birta lithium. Marka hore, bandhigga SOC waa mid aan sax ahayn: tusaale ahaan, qoraagu wuxuu dhawaan la kulmay Xpeng P5, kaas oo qaatay 50 daqiiqo inuu ku dallaco 20% ilaa 99%, halka laga soo dallacay 99% ilaa Waxay qaadatay 30 daqiiqo si loo gaaro 100%, taas oo iska cad. dhibaato ka haysata bandhigga SOC; labaad, xawaaraha korontadu waa mid aan sinnayn (sidoo kale inta badan waxay dhacdaa marka si buuxda loo dallaco): baabuurta qaar ma muujiyaan wax isbeddel ah oo ku yimaadda nolosha batteriga ka dib markay 10km kaxeeyaan ka dib markii si buuxda loo dallacay, halka baabuurta qaarkood aysan dhicin. Cimrigii baytarigu waxa uu hoos ugu dhacay 5km dhawr tallaabo ka dib. Sidaa darteed, baytariyada fosfooraska birta ee lithium waa in si buuxda loo dallaci toddobaadkii hal mar si loo saxo joogteynta unugyada.

Taas beddelkeeda, dabeecadda maaddada awgeed, baytariyada lithium-ka ternary kuma habboona baarkinka ka dib marka si buuxda loo dallaco (laakiin waxay sii wadi karaan baabuur wadista in ka yar 90% isla markiiba ka dib marka si buuxda loo dallaco).Intaa waxaa dheer, iyada oo aan loo eegin nooca baytarigu, waa in aan lagu wadin xaaladaha batari hooseeya (SOC <20%), sidoo kale waa in lagu dallaco deegaan aad u daran (heerkulka ka sarreeya 30°C ama ka hooseeya 0°C).

Marka loo eego xawaaraha dallacaadda, hababka dallacaadda ayaa loo qaybin karaa dallacaadda degdegga ah iyo dallacaadda gaabis ah.

(1)Dallacaadda degdega ah

Korantada dallacaadda ee dallacaadda degdegga ah guud ahaan waa tamarta shaqada ee baabuurta korontada (inta badan agagaarka 360-400V). Awoodda sare ee awoodda, hadda wuxuu gaari karaa 200-250A, oo u dhiganta 70-100kW ee awoodda. Qaar ka mid ah moodooyinka leh dallacaadda sida barta wax lagu iibinayo waxay gaari karaan 150kW iyada oo loo marayo danab sare. sare. Baabuurta badankoodu waxay dalaci karaan 30% ilaa 80% nus saac gudaheed.

[Tusaale] Qaadashada baabuurka leh awoodda baytarigu yahay 60 darajo (oo leh qiyaastii 500km) tusaale ahaan, ku dallaca degdega ah (awood 60kW)ku qaado batarinolosha 250km nus saac gudaheed
