Kunyangwe paine nhau dzeakasimba-state mabhatiri nguva pfupi yadarika, kuchine matambudziko mazhinji ekugadzirisa mabhatiri ehurumende. Pachine rwendo rurefu rwekuenda kune yayo yekutengeserana misa kugadzirwa uye kushandiswa mumotokari itsva simba. 48VAGV lithium battery.jpg

Ikozvino hukuru hwemabhatiri emagetsi ichiri ternary mabhatiri uye lithium iron phosphate mabhatiri. Munguva yakapfuura, mabhatiri e-lithium iron phosphate anga achiwedzera simba, uye mota zhinji dzinotakura vanhu dzakachinja kubva kumabhatiri e-ternary kuenda ku lithium iron phosphate mabhatiri.

Ichi chinyorwa chinotarisa mutsauko uripo pakati pemabhatiri eternary uye lithium iron phosphate mabhatiri kubva pamaonero mashanu: chengetedzo, simba remagetsi, kuderera-kupisa kuburitsa, kunyatsochaja, uye kutenderera hupenyu.

1. chibatiso

Iyo blade bhatiri i lithium iron phosphate bhatiri. Iyo blade bhatiri yakaratidza kuti inogona kupasa yakaoma acupuncture bvunzo, nepo ternary bhatiri haigone. Naizvozvo, iyo lithium iron phosphate bhatiri ibhatiri rakachengeteka kupfuura ternary bhatiri.

Uye zvakare, iyo yekudziya kugadzikana kwelithium iron phosphate cathode zvinhu pachayo iri nani kupfuura iyo yeternary lithium. Iine kugadzikana kwakanyanya mukati me500 degrees Celsius. Thermal runaway inoitika kana ichipfuura 800 degrees Celsius. Mukuwedzera, kunyange kana kupisa kunopisa kunoitika, Kubudiswa kwekushisa kwe lithium iron phosphate bateri kunononokawo, uye hakuzosununguri okisijeni kana yakaora, kuderedza ngozi yemoto.

Kusiyana neizvi, ternary lithium mabhatiri anotanga kunyungudika panosvika 300 degrees Celsius. Mukutsva kwemagetsi emagetsi matsva, ternary lithium bhatiri modhi inotora chikamu chakakura.

2. Kuwanda kwesimba

Zvinoenderana neruzhinji ruzivo kubva kumakambani epamba, zvakajairika kuti mabhatiri epamusoro-soro ave nesimba rimwechete re 250Wh/kg kana kupfuura, nepo bhatiri remukati relithium iron phosphate rine simba rimwechete rinosvika 180Wh/kg.

Kubva pane iyi maonero, ternary bhatiri ine nani simba density kupfuura lithium iron phosphate bhatiri.

Kunyangwe blade bhatiri rakagadzirwa neBYD rakavandudza kubatanidzwazve kwesero rebhatiri, uye volumetric simba density yakawedzera kusvika 50%, uku kushanduka kwemaitiro. Iyo yega simba density ye lithium iron phosphate bhatiri haina kuwedzera.

3. Kubuda kwekushisa kwakadzika

Mukuenzanisa, paminus 20 degrees Celsius, ternary lithium mabhatiri ane mabhenefiti ari pachena pane lithium iron phosphate mabhatiri.

4. Kuchaja kushanda zvakanaka

Parizvino, nzira yakajairika yekuchaja pamusika inogara iripo uye inogara ichichaja voltage. Inowanzoitwa pakutanga kwekuchaja. Constant current kuchaja ndiyo inotanga kushandiswa. Panguva ino, ikozvino yakakura uye kukwanisa kuchaja kwakawedzera. Kana iyo voltage inosvika pane imwe kukosha, inoderera. Ikozvino inoshandurwa kuti igare ichichaja voltage, kuitira kuti bhatiri rigone kubhadharwa zvizere.

Muchiitiko ichi, chiyero chehuwandu hwehuwandu hwekuchaja huwandu hwebhatiri huwandu hunonzi chiyero chemazuva ese, iyo yakakosha kukosha kuyera kubhadharisa kwechikwata chebhatiri panguva yekuchaja. Kazhinji, iyo yakakura iyo muzana, iyo yakawanda yemagetsi inochajirwa muchikamu chinogara chiripo. Iyo yakakwirira, iyo yakakwirira yekuchajisa kwebhatiri kunoratidzwa.

Chiyero chehuwandu hwekuchajisa uye kubuda ikozvino kune yakazara bhatiri ndiyo yekuchaja uye yekuburitsa mwero. Inogona kuonekwa kubva kune data iyo apo ternary lithium bhatiri uye lithium iron phosphate bhatiri inobhadharwa pachiyero pasi pegumi gumi, hapana misiyano inokosha muhuwandu hwemazuva ose. Iyo inogara iripo ikozvino chiyero chesimbi-lithium bhatiri inokurumidza kuderedzwa, uye iyo yekuchaja inoshanda inokurumidza kuderedzwa. Zvinogona kuoneka kuti ternary lithium bhatiri ine mukana wakakura maererano nekuchaja kunyatsoita.

5. Kutenderera hupenyu

Kana iyo yakasara simba iri 80% yehutano hwekutanga sekuguma kwekuedzwa, ikozvino laboratory test ye lithium iron phosphate bateri ine hupenyu hwehupenyu hunopfuura 3,500 nguva, uye vamwe vasvika 5,000 nguva.

Hupenyu hwekuyedza kutenderera kweternary lithium bhatiri ingangoita 2500 nguva. Padanho rehupenyu hwekutenderera, iyo lithium iron phosphate bhatiri ine hupenyu hwechokwadi hwakareba kupfuura iyo ternary lithium bhatiri.

Pasi pehuwandu hwakafanana hwekutenderera, huwandu hwasara hwelithium iron phosphate bhatiri inongowanda kupfuura iyo yeternary lithium bhatiri. Iyo ternary lithium bhatiri inotenderedzwa 3900 nguva uye yakasara inokwana 66%. Iyo lithium iron phosphate bhatiri inotenderera 5000 nguva uye yakasara inokwana 84%. Lithium iron phosphate bhatiri ine zviri pachena zvakanakira.

Kubva pakuongorora kwepamusoro, zvinogona kuonekwa kuti lithium iron phosphate ine mabhenefiti ari pachena maererano nekuchengetedza uye kutenderera hupenyu; mabhatiri e-ternary akakwirira mukuwanda kwesimba, kubuda-kudzika-tembiricha, uye kunyatsochaja.

Ehe, hazvireve kuti ndeipi yemabhatiri maviri ari nani, nekuti ivo vese vane yavo yakanakisa yekushandisa mamiriro.
