1. Roj teeb lub zogceev

Endurance yog ib qho tseem ceeb tshaj plaws ntawm kev ua yeeb yam ntawm lub tsheb hluav taws xob, thiab yuav ua li cas nqa cov roj teeb ntau dua hauv qhov chaw txwv yog txoj hauv kev ncaj qha tshaj plaws los ua kom muaj zog mus ntev.Yog li, qhov ntsuas tseem ceeb los ntsuas cov roj teeb ua haujlwm yog lub zog hluav taws xob tsis muaj zog, uas yog qhov hnyav dua, lub zog hluav taws xob ntau dua , thiab qhov ntev ntawm kev ua siab ntev kuj yog;Nyob rau tib lub zog, qhov siab dua lub zog ntawm lub roj teeb, qhov sib dua ntawm lub roj teeb.Peb paub tias qhov hnyav muaj qhov cuam tshuam zoo rau kev siv zog.Yog li ntawd, tsis muaj teeb meem los ntawm qhov twg los ntawm qhov pom, ua kom lub zog ceev ntawm lub roj teeb yog sib npaug rau kev ua kom lub zog ntawm lub tsheb.
Los ntawm cov cuab yeej siv tam sim no, lub zog ceev ntawm ternary lithium roj teeb feem ntau yog 200wh / kg, uas yuav ncav cuag 300wh / kg yav tom ntej;Tam sim no, lub roj teeb lithium hlau phosphate pib hovers ntawm 100 ~ 110wh / kg, thiab qee qhov tuaj yeem ncav cuag 130 ~ 150wh / kg.BYD tau tso tawm lub cim tshiab ntawm lithium hlau phosphate roj teeb "hniav roj teeb" hauv lub sijhawm.Nws "ntim qhov tshwj xeeb lub zog ceev" yog 50% siab dua li cov roj teeb lithium hlau phosphate, tab sis nws kuj nyuaj rau kev tawg ntawm 200wh / kg.

2. Kub kub tsis kam

Kev nyab xeeb yog ib qho teeb meem tseem ceeb ntawm lub tsheb hluav taws xob, thiab kev nyab xeeb ntawm cov roj teeb yog qhov tseem ceeb tshaj plaws ntawm cov tsheb hluav taws xob.Lub roj teeb lithium ternary yog qhov kub thiab txias thiab yuav decompose ntawm li 300 degrees, thaum cov khoom siv lithium hlau phosphate yog li 800 degrees.Ntxiv mus, cov tshuaj tiv thaiv ntawm ternary lithium cov khoom yog khaus, uas yuav tso tawm cov pa oxygen molecules, thiab cov electrolyte yuav hlawv sai heev nyob rau hauv qhov kev txiav txim ntawm kub kub.Yog li ntawd, cov kev cai ntawm ternary lithium roj teeb rau BMS system yog siab heev, thiab tiv thaiv overtemperature tiv thaiv ntaus ntawv thiab roj teeb tswj system yog xav tau los tiv thaiv kev ruaj ntseg ntawm roj teeb.

3. Tsawg kub adaptability

Lub attenuation ntawm hluav taws xob tsheb mileage nyob rau lub caij ntuj no yog mob taub hau rau lub tsheb lag luam.Feem ntau, qhov tsawg kawg nkaus kev pabcuam kub ntawm lithium hlau phosphate tsis qis dua - 20 ℃, thaum qhov tsawg kawg nkaus ntawm ternary lithium tuaj yeem qis dua - 30 ℃.Nyob rau hauv ib puag ncig uas tsis tshua muaj kub, lub peev xwm ntawm ternary lithium yog siab dua li ntawm lithium hlau phosphate.Piv txwv li, ntawm rho tawm 20 ° C, ternary lithium roj teeb tuaj yeem tso tawm txog 80% ntawm lub peev xwm, Lub roj teeb lithium hlau phosphate tsuas tuaj yeem tso tawm li 50% ntawm nws lub peev xwm.Tsis tas li ntawd, qhov tso tawm platform ntawm ternary lithium roj teeb nyob rau hauv qhov kub thiab txias ib puag ncig yog ntau dua li ntawm lithium hlau phosphate roj teeb, uas tuaj yeem muab kev ua si ntau dua rau lub peev xwm ntawm lub cev muaj zog thiab lub zog zoo dua.

4. Kev them nqi ua haujlwm

Tsis muaj qhov sib txawv ntawm qhov tam sim no them lub peev xwm / tag nrho qhov muaj peev xwm piv ntawm ternary lithium roj teeb thiab lithium hlau phosphate roj teeb thaum them tsis tshaj 10 C. thaum them ntawm tus nqi siab tshaj 10 C, lub peev xwm them tam sim no / tag nrho lub peev xwm ratio ntawm lithium hlau phosphate roj teeb yog me me.Qhov loj dua tus nqi them, qhov pom tseeb dua qhov txawv ntawm qhov tam sim no them lub peev xwm / tag nrho cov peev txheej thiab cov khoom siv roj teeb ternary, Qhov no feem ntau cuam tshuam nrog kev hloov pauv me me ntawm lithium hlau phosphate ntawm 30% ~ 80% SOC.
5. Lub neej voj voog
Roj teeb muaj peev xwm attenuation yog lwm qhov mob ntawm lub tsheb hluav taws xob.Tus naj npawb ntawm tag nrho cov nqi thiab tawm mus ntawm lithium hlau phosphate roj teeb yog ntau dua 3000, thaum lub neej kev pab cuam ntawm ternary lithium roj teeb luv dua li ntawm lithium hlau phosphate roj teeb.Yog hais tias tus naj npawb ntawm tag nrho cov nqi thiab tawm mus ntau dua 2000, attenuation yuav pib tshwm.
6. Tus nqi tsim khoom
Nickel thiab cobalt cov ntsiab lus tsim nyog rau ternary lithium roj teeb yog cov hlau muaj txiaj ntsig, thaum lub roj teeb lithium hlau phosphate tsis muaj cov khoom siv hlau muaj txiaj ntsig, yog li tus nqi ntawm ternary lithium roj teeb kuj tseem siab.

Rau Tag Nrho: ternary lithium roj teeb lossis lithium hlau phosphate roj teeb muaj lawv tus kheej qhov zoo thiab qhov tsis zoo.Tam sim no, lawv muaj cov neeg sawv cev sib txawv.Cov neeg tsim khoom tau ua txhaum los ntawm cov kev txwv kev cuam tshuam thiab tsuas yog xaiv lub roj teeb ntawm cov khoom siv raws li cov kev xav tau tshwj xeeb
