1. Matla a betritekano

Mamello ke e 'ngoe ea litšoantšiso tsa bohlokoa ka ho fetisisa tsa likoloi tsa motlakase, le mokhoa oa ho jara libeteri tse ngata sebakeng se lekanyelitsoeng ke tsela e tobileng ka ho fetisisa ea ho eketsa mileage ea mamello.Ka hona, index ea bohlokoa ea ho lekola ts'ebetso ea betri ke matla a matla a betri, e leng feela matla a motlakase a teng ka har'a betri ka boima ba yuniti kapa bophahamo, tlas'a molumo kapa boima bo tšoanang, Ha matla a matla a phahame, matla a motlakase a tla fanoa. , ’me mamello e lekanyelitsoe ka nako e telele;Boemong bo ts'oanang ba matla, ha matla a betri a phahame, boima ba betri bo fokotseha.Rea tseba hore boima bo na le tšusumetso e kholo tšebelisong ea matla.Ka hona, ho sa tsotellehe hore na ho na le pono efe, ho eketsa matla a matla a betri ho lekana le ho eketsa mamello ea koloi.
Ho tloha thekenoloji ea morao-rao, matla a matla a betri ea ternary lithium hangata ke 200wh / kg, e ka fihlang ho 300wh / kg nakong e tlang;Hajoale, betri ea lithium iron phosphate ha e le hantle e fofa ho 100 ~ 110wh / kg, 'me e meng e ka fihla ho 130 ~ 150wh / kg.BYD e lokolitse moloko o mocha oa betri ea lithium iron phosphate "blade battery" ka nako."Tekanyo e khethehileng ea matla" ea eona e phahame ka 50% ho feta ea betri ea setso ea lithium iron phosphate, empa ho thata ho phunyeletsa 200wh / kg.

2. Ho hanyetsa mocheso o phahameng

Tšireletseho ke e 'ngoe ea mathata a mantlha a likoloi tsa motlakase,' me polokeho ea libeteri ke eona ntho e tlang pele ho likoloi tsa motlakase.The ternary lithium battery e na le maikutlo a matla haholo mocheso 'me e tla bola ka likhato tse ka bang 300, ha thepa ea lithium iron phosphate e ka ba likhato tse 800.Ho feta moo, lik'hemik'hale tsa lik'hemik'hale tsa ternary lithium li matla haholo, tse tla lokolla limolek'hule tsa oksijene, 'me electrolyte e tla chesa ka potlako tlas'a ketso ea mocheso o phahameng.Ka hona, litlhoko tsa ternary lithium betri bakeng sa sistimi ea BMS li phahame haholo, 'me sesebelisoa sa tšireletso se khahlanong le mocheso le sistimi ea taolo ea betri lia hlokahala ho sireletsa polokeho ea betri.

3. Ho ikamahanya le maemo a tlaase a mocheso

Ho fokotseha ha lik'hilomithara tsa koloi ea motlakase nakong ea mariha ke hlooho e bohloko bakeng sa likhoebo tsa likoloi.Ka kakaretso, mocheso o fokolang oa tšebeletso oa lithium iron phosphate ha o tlase ho -20 ℃, ha mocheso o tlase oa ternary lithium o ka ba tlase ho -30 ℃.Tlas'a tikoloho e tšoanang ea mocheso o tlase, matla a ternary lithium a phahame haholo ho feta a lithium iron phosphate.Ka mohlala, ka ho fokotsa 20 ° C, ternary lithium betri e ka lokolla hoo e ka bang 80% ea matla, Betri ea lithium iron phosphate e ka lokolla hoo e ka bang 50% ea matla a eona.Ntle le moo, sethala sa ho ntša betri ea ternary lithium sebakeng sa mocheso o tlase se phahame haholo ho feta sa betri ea lithium iron phosphate, e ka fanang ka papali e kholo ho bokhoni ba motlakase le matla a betere.

4. Ts'ebetso ea ho tjhaja

Ha ho na phapang e totobetseng pakeng tsa matla a kamehla a ho tjhaja / kakaretso ea matla a ternary lithium betri le lithium iron phosphate battery ha e tjhaja ka mokhoa o sa feteng 10 C. ha e tjhaja ka tekanyo e ka holimo ho 10 C, matla a kamehla a ho tjhaja / matla a kakaretso. karo-karolelano ea betri ea lithium iron phosphate e nyane.E kholoanyane sekhahla sa ho tjhaja, phapang e totobetseng pakeng tsa matla a kamehla a ho tjhaja / kakaretso ea bokhoni ba karo-karolelano le betri ea thepa ea ternary, Sena se amana haholo le phetoho e nyenyane ea lithium iron phosphate ho 30% ~ 80% SOC.
5. Bophelo ba potoloho
Ho fokotsa matla a betri ke ntlha e 'ngoe e bohloko ea likoloi tsa motlakase.Palo ea litefiso tse felletseng tsa betri ea lithium iron phosphate e kholo ho feta 3000, athe bophelo ba ts'ebeletso ea ternary lithium betri bo khuts'oane ho feta ba betri ea lithium iron phosphate.Haeba palo ea lipotoloho tse felletseng tsa tefiso le ho tsoa li le kholo ho feta 2000, ho fokotseha ho tla qala ho hlaha.
6. Litšenyehelo tsa tlhahiso
Lintho tsa nickel le cobalt tse hlokahalang bakeng sa libeteri tsa ternary lithium ke litšepe tsa bohlokoa, athe libeteri tsa lithium iron phosphate ha li na lisebelisoa tsa tšepe tsa bohlokoa, kahoo theko ea libeteri tsa ternary lithium e batla e phahame.

Kakaretso: ternary lithium battery kapa lithium iron phosphate battery li na le melemo le mathata a tsona.Hona joale, ba na le baemeli ba fapaneng.Baetsi ba tlola lithibelo tse amehang tsa tekheniki mme ba khetha feela betri ea lisebelisoa tse tsamaellanang ho latela litlhoko tse ikhethang
