1. Mphamvu ya batrikachulukidwe

Kupirira ndi chimodzi mwazinthu zofunika kwambiri zamagalimoto amagetsi, komanso momwe munganyamulire mabatire ambiri pamalo ocheperako ndi njira yolunjika kwambiri yowonjezerera kupirira mtunda.Chifukwa chake, cholozera chofunikira chowunika momwe batire imagwirira ntchito ndi kuchuluka kwa mphamvu ya batri, yomwe imangokhala mphamvu yamagetsi yomwe ili mu batri pa kulemera kwa yuniti kapena voliyumu, pansi pa voliyumu kapena kulemera komweko, Kuchuluka kwa mphamvu yamagetsi, mphamvu zamagetsi zambiri zidzaperekedwa. , ndipo pamene chipirirocho chimakhala chotalika;Pa mlingo womwewo wa mphamvu, mphamvu ya mphamvu ya batire imakwera kwambiri, mphamvu ya batire imapepuka.Tikudziwa kuti kulemera kumakhudza kwambiri kugwiritsa ntchito mphamvu.Choncho, ziribe kanthu kuti ndikuwona liti, kuwonjezereka kwa mphamvu ya batri ndikofanana ndi kuonjezera kupirira kwa galimotoyo.
Kuchokera zamakono zamakono, kachulukidwe mphamvu ya ternary lithiamu batire zambiri 200wh / kg, amene akhoza kufika 300wh / kg m'tsogolo;Pakali pano, batire ya lithiamu chitsulo mankwala kwenikweni imayenda pa 100 ~ 110wh / kg, ndipo ena akhoza kufika 130 ~ 150wh / kg.BYD idatulutsa m'badwo watsopano wa batri ya lithiamu iron phosphate "blade battery" mu nthawi."Kachulukidwe kake kachulukidwe kamphamvu" ndi 50% kuposa batire yachikhalidwe ya lithiamu iron phosphate, komanso ndizovuta kuthyola 200wh / kg.

2. Kukana kutentha kwakukulu

Chitetezo ndi chimodzi mwazovuta zazikulu zamagalimoto amagetsi, ndipo chitetezo cha mabatire ndichofunika kwambiri pamagalimoto amagetsi.Batire ya ternary lithiamu imakhudzidwa kwambiri ndi kutentha ndipo imatha kuwola pafupifupi madigiri 300, pomwe zinthu za lithiamu iron phosphate zimakhala pafupifupi madigiri 800.Kuphatikiza apo, zochita za mankhwala a ternary lithiamu zakuthupi ndizowonjezereka, zomwe zimamasula mamolekyu a okosijeni, ndipo ma electrolyte amawotcha mwachangu chifukwa cha kutentha kwambiri.Chifukwa chake, zofunikira za ternary lithiamu batire ya dongosolo la BMS ndizokwera kwambiri, ndipo chipangizo choteteza kutentha kwambiri ndi kasamalidwe ka batri ndizofunikira kuteteza chitetezo cha batri.

3. Kusinthasintha kwa kutentha kochepa

The attenuation wa magetsi galimoto mtunda m'nyengo yozizira ndi mutu kwa mabizinesi galimoto.Nthawi zambiri, kutentha kocheperako kwa lithiamu iron phosphate sikutsika kuposa -20 ℃, pomwe kutentha kwa ternary lithiamu kumatha kutsika kuposa -30 ℃.Pansi pa kutentha komweko, mphamvu ya ternary lithiamu ndiyokwera kwambiri kuposa ya lithiamu iron phosphate.Mwachitsanzo, pa opanda 20 ° C, ternary lithiamu batire akhoza kumasula pafupifupi 80% ya mphamvu, The lithiamu chitsulo mankwala batire akhoza kumasula pafupifupi 50% ya mphamvu zake.Komanso, kutulutsa nsanja ya ternary lithiamu batire mu malo otsika kutentha ndi apamwamba kwambiri kuposa lifiyamu chitsulo mankwala batire, amene angapereke kusewera kwambiri luso galimoto ndi mphamvu bwino.

4. Kulipira ntchito

Palibe kusiyana koonekeratu pakati pa nthawi zonse pakali pano kulipiritsa mphamvu / okwana mphamvu chiŵerengero cha ternary lithiamu batire ndi lithiamu chitsulo mankwala batire pamene kulipiritsa pa zosaposa 10 C. pamene nawuza pa mlingo pamwamba 10 C, zonse panopa kulipiritsa mphamvu / okwana mphamvu chiŵerengero cha batire ya lithiamu iron phosphate ndi yaying'ono.Kuchulukirachulukira kwa chiwongolero, kumakhalanso koonekeratu kusiyana pakati pa kuchuluka komwe kulipo / kuchuluka kwa mphamvu ndi batire ya ternary, Izi zimagwirizana kwambiri ndi kusintha kwamphamvu kwa lifiyamu chitsulo phosphate pa 30% ~ 80% SOC.
5. Moyo wozungulira
Kuchepetsa mphamvu ya batri ndi malo ena opweteka a magalimoto amagetsi.Chiwerengero cha amalipiritsa wathunthu ndi kutulutsa mkombero wa lithiamu chitsulo mankwala batire ndi wamkulu kuposa 3000, pamene moyo utumiki wa ternary lithiamu batire ndi lalifupi kuposa lifiyamu chitsulo mankwala batire.Ngati kuchuluka kwa ndalama zonse ndi kutulutsa kupitilira 2000, kutsitsa kumayamba kuwonekera.
6. Mtengo wopangira
Zinthu za Nickel ndi cobalt zofunika pa mabatire a ternary lithiamu ndi zitsulo zamtengo wapatali, pamene mabatire a lithiamu iron phosphate alibe zitsulo zamtengo wapatali, choncho mtengo wa mabatire a ternary lithiamu ndi wokwera kwambiri.

To Total: ternary lithiamu batire kapena lithiamu iron phosphate batire ili ndi zabwino ndi zovuta zake.Pakali pano, ali ndi oimira osiyanasiyana.Opanga akudutsa muzoletsa zofunikira zaukadaulo ndikusankha batire ya zinthu zomwe zimagwirizana malinga ndi zosowa zenizeni
