1. Amandla ebhetriukuxinana

Ukunyamezela ngomnye wemisebenzi ebalulekileyo yezithuthi zombane, kunye nendlela yokuthwala iibhetri ezininzi kwindawo elinganiselweyo yeyona ndlela ichanekileyo yokwandisa i-mileage yokunyamezela.Ke ngoko, isalathiso esiphambili sokuvavanya ukusebenza kwebhetri kukuxinaniswa kwamandla ebhetri, nto leyo ingamandla ombane aqulethwe kwibhetri ngeyunithi yobunzima okanye umthamo, phantsi komthamo ofanayo okanye ubunzima, Ukuphakama koxinano lwamandla, amandla ombane amaninzi aya kubonelelwa. , yaye okukhona unyamezelo lusiba lude;Kwinqanaba lamandla afanayo, kokukhona ubuninzi bamandla ebhetri, kokukhona bukhaphukhaphu ubunzima bebhetri.Siyazi ukuba ubunzima bunempembelelo enkulu ekusebenziseni amandla.Ngoko ke, kungakhathaliseki ukuba yeyiphi imbono, ukwandisa ubuninzi bamandla ebhetri bulingana nokunyusa ukunyamezela kwesithuthi.
Ukusuka kwitekhnoloji yangoku, ukuxinana kwamandla ebhetri ye-lithium ye-ternary ngokuqhelekileyo yi-200wh / kg, enokufikelela kwi-300wh / kg kwixesha elizayo;Okwangoku, ibhetri ye-lithium ye-iron phosphate ngokusisiseko ijikeleza kwi-100 ~ 110wh / kg, kwaye abanye banokufikelela kwi-130 ~ 150wh / kg.I-BYD ikhuphe isizukulwana esitsha se-lithium iron phosphate battery “blade battery” ngexesha."Ubuninzi bomthamo wamandla athile" yi-50% ephezulu kunebhetri ye-lithium yentsimbi ye-phosphate yendabuko, kodwa kunzima ukunqumla i-200wh / kg.

2. Ukumelana nobushushu obuphezulu

Ukhuseleko yenye yeengxaki eziphambili zezithuthi zombane, kwaye ukhuseleko lweebhetri luyiyona nto iphambili kwizithuthi zombane.Ibhetri ye-lithium ye-ternary ivakalelwa kakhulu kwiqondo lokushisa kwaye iya kubola malunga nama-degrees angama-300, ngelixa i-lithium iron phosphate impahla imalunga ne-800 degrees.Ngaphezu koko, ukuphendulwa kweekhemikhali ze-ternary lithium material kunamandla ngakumbi, okuya kukhulula iamolekyu ze-oksijeni, kwaye i-electrolyte iya kutshisa ngokukhawuleza phantsi kwesenzo sokushisa okuphezulu.Ke ngoko, iimfuno ze-ternary lithium ibhetri yenkqubo ye-BMS ziphezulu kakhulu, kwaye isixhobo sokukhusela ubushushu obugqithisileyo kunye nenkqubo yolawulo lwebhetri ziyafuneka ukukhusela ukhuseleko lwebhetri.

3. Ukulungelelaniswa kobushushu obuphantsi

Ukunciphisa i-mileage yesithuthi sombane ebusika yintloko kumashishini ezithuthi.Ngokuqhelekileyo, ubushushu benkonzo obuncinci be-lithium iron phosphate ayikho ngaphantsi kwe-20 ℃, ngelixa ubuncinane bokushisa kwe-ternary lithium bunokuba ngaphantsi kwe-30 ℃.Ngaphantsi kwendawo efanayo yobushushu obuphantsi, umthamo we-ternary lithium uphezulu kakhulu kune-lithium iron phosphate.Ngokomzekelo, kwi-minus 20 ° C, ibhetri ye-lithium ye-ternary inokukhupha malunga ne-80% yomthamo, Ibhetri ye-lithium ye-phosphate inokukhulula kuphela malunga ne-50% yomthamo wayo.Ukongeza, iqonga lokukhupha ibhetri ye-ternary lithium kwindawo yobushushu obuphantsi iphezulu kakhulu kunebhetri ye-lithium iron phosphate, enokunika umdlalo omkhulu kwisakhono semoto kunye namandla angcono.

4. Ukutshaja ukusebenza

Akukho mahluko ucacileyo phakathi komthamo wokutshaja oqhubekayo wangoku / umthamo opheleleyo webhetri ye-lithium ye-lithium kunye nebhetri ye-lithium ye-phosphate xa utshaja ungekho ngaphezu kwe-10 C. ibhetri ye-lithium iron phosphate incinci.Ubukhulu bezinga lokutshaja, kokukhona umahluko phakathi komthamo wokutshaja oqhubekayo wangoku / umlinganiselo womthamo opheleleyo kunye nebhetri ye-ternary, Oku kunxulumene ikakhulu notshintsho ombane omncinci we-lithium iron phosphate kwi-30% ~ 80% SOC.
5. Ubomi bomjikelo
Ukunciphisa umthamo webhetri yenye indawo yeentlungu zeenqwelo zombane.Inani lentlawulo epheleleyo kunye nemijikelezo yokukhupha ibhetri ye-lithium ye-iron phosphate ingaphezulu kwe-3000, ngelixa ubomi benkonzo ye-ternary lithium ibhetri bufutshane kunobo bebhetri ye-lithium iron phosphate.Ukuba inani lemijikelezo yentlawulo epheleleyo kunye nokukhupha ingaphezulu kwe-2000, ukuthotywa kuya kuqala ukubonakala.
6. Iindleko zemveliso
Izinto ze-nickel kunye ne-cobalt eziyimfuneko kwiibhetri ze-lithium ze-ternary zintsimbi ezixabisekileyo, ngelixa iibhetri ze-lithium iron phosphate aziqukethe izinto ezixabisekileyo zetsimbi, ngoko ke ixabiso leebhetri ze-ternary lithium liphezulu.

Ukuya kwiTotali: ibhetri ye-lithium ye-ternary okanye ibhetri ye-lithium iron phosphate ineenzuzo zabo kunye nokungalunganga.Okwangoku, banabameli abahlukeneyo.Abavelisi baphula kwizithintelo ezifanelekileyo zobugcisa kwaye bakhethe kuphela ibhetri yezinto ezihambelanayo ngokweemfuno ezithile
