Chii chinonzi lithium bhatiri module?

Mhedziso yemamodule ebhatiri

Battery modules chikamu chakakosha chemotokari dzemagetsi.Basa ravo nderekubatanidza masero ebhatiri akawanda pamwechete kuti aumbe akazara kupa simba rakakwana kuti mota dzemagetsi dzishande.

Battery modules zvikamu zvebhatiri zvinoumbwa nemasero ebhatiri akawanda uye chikamu chakakosha chemotokari dzemagetsi.Basa ravo nderekubatanidza masero ebhatiri akawanda pamwechete kuti aumbe akazara kupa simba rakakwana kumotokari dzemagetsi kana mabasa ekuchengetedza simba.Battery modules haisi iyo chete magetsi emagetsi emotokari, asiwo imwe yeanonyanya kukosha ekuchengetedza simba.

Kuberekwa kwebhatiri modules

Kubva pamaonero eindasitiri yekugadzira michina, mabhatiri e-single-sero ane matambudziko akadai seasina kusimba emagetsi zvivakwa uye asina hushamwari ekunze ekunze, kunyanya kusanganisira:

1. Mamiriro ekunze ekunze akadai sehukuru uye chitarisiko haana kugadzikana, uye achachinja zvakanyanya nehupenyu hwekufamba;

2. Kushaikwa nyore uye yakavimbika mechanical installation uye kugadzirisa interface;

3. Kushaikwa kwekubatana kwakanakira kubuda uye chimiro chekutarisa chimiro;

4. Michina isina simba uye kudzivirira kudzivirira.

Nemhaka yokuti mabhatiri e-sero-sero ane matambudziko ari pamusoro apa, zvakakosha kuwedzera mutsara kuti uchinje uye ugadzirise, kuitira kuti bhatiri rigone kuunganidzwa uye rinosanganiswa nemotokari yose nyore nyore.Iyo module inoumbwa akati wandei kusvika gumi kana makumi maviri mabhatiri, ane yakagadzikana yekunze mamiriro, ari nyore uye akavimbika mashini, kuburitsa, yekutarisa interface, uye yakawedzera kuvharirwa uye kudzivirira kwemuchina mhedzisiro yekusarudzwa kwechisikigo.

Iyo yazvino chiyero module inogadzirisa akasiyana matambudziko emabhatiri uye ine anotevera mabhenefiti makuru:

1. Inogona kuona zviri nyore kugadzira otomatiki uye ine hunyanzvi hwekugadzira, uye mhando yechigadzirwa uye mutengo wekugadzira zviri nyore kudzora;

2. Inogona kuumba yakakwira dhigirii yekumisikidza, iyo inobatsira kudzikisa zvakanyanya mutsetse mutengo wekugadzira uye kuvandudza kugadzirwa kwekugadzira;yakajairwa machinjiro uye maratidziro anobatsira kumakwikwi akazara emusika uye kusarudzwa kwenzira mbiri, uye kuchengetedza kushanda kuri nani kwekushandiswa kwecascade;

3. Kuvimbika kwakanakisa, iyo inogona kupa yakanaka mechanical uye kudzivirira kudzivirira kwemabhatiri mukati mehupenyu hwese;

4. Zvine mari yakaderera mbishi mari haizoise yakawandisa kudzvanya pane yekupedzisira simba system gungano mutengo;

5. Iyo shoma inochengetedza unit value inenge iduku, iyo ine simba guru pakuderedza mushure mekutengesa mari.

Kuumbwa kwemaitiro ebhatiri module

Iyo yekuumbwa chimiro chebhatiri module kazhinji inosanganisira bhatiri cell, bhatiri manejimendi system, bhatiri bhokisi, bhatiri chinongedzo uye zvimwe zvikamu.Battery cell ndiyo inonyanya kukosha yebhatiri module.Iyo inoumbwa neakawanda mabhatiri mayuniti, kazhinji lithium-ion bhatiri, iyo ine hunhu hwepamusoro simba density, yakaderera yekuzviburitsa mwero uye hupenyu hurefu hwebasa.

Battery management system iripo kuti ive nechokwadi chekuchengetedza, kuvimbika uye hupenyu hurefu hwebhatiri.Mabasa ayo makuru anosanganisira kutarisa mamiriro ebhatiri, kudzora tembiricha yebhatiri, bhatiri kuwandisa / pamusoro pekudzivirira kuburitsa, nezvimwe.

Bhatiri bhokisi ndiro rekunze goko rebhatiri module, rinoshandiswa kuchengetedza bhatiri module kubva kune ekunze nharaunda.Bhokisi rebhatiri rinowanzo gadzirwa nesimbi kana epurasitiki zvinhu, ine corrosion resistance, moto kuramba, kuputika kuramba uye humwe hunhu.

Bhatiri yekubatanidza inhengo inobatanidza akawanda bhatiri maseru kuita akazara.Inowanzo gadzirwa nemhangura, ine conductivity yakanaka, kupfeka kusagadzikana uye kusagadzikana kwekuora.

Battery module performance zviratidzo

Kupikiswa kwemukati (Internal resistance) kunoreva kupikisa kwezvino kuyerera nemubhatiri kana bhatiri riri kushanda, izvo zvinokanganiswa nezvinhu zvakaita semidziyo yebhatiri, nzira yekugadzira uye chimiro chebhatiri.Iyo yakakamurwa kuva ohmic yemukati kushorwa uye polarization yemukati kuramba.Ohmic yemukati inopikisa inoumbwa nekusangana kwekupikisa kwezvinhu zve electrode, electrolytes, diaphragms uye zvikamu zvakasiyana;polarization yemukati kuramba inokonzerwa ne electrochemical polarization uye concentration musiyano polarization.

Simba chairo - simba rebhatiri pavhoriyamu yevhoriyamu kana huwandu.

Kubhadhara uye kuburitsa kushanda zvakanaka - chiyero chechiyero chekuti simba remagetsi rinoshandiswa nebhatiri panguva yekuchaja rinoshandurwa kuita kemikari simba iro bhatiri rinogona kuchengeta.

Voltage - mutsauko unokwanisa pakati peiyo yakanaka uye yakaipa electrode yebhatiri.

Open circuit voltage: voltage yebhatiri kana pasina dunhu rekunze kana mutoro wekunze wakabatana.Iyo yakavhurika yedunhu voltage ine humwe hukama nehuremu hwasara hwebhatiri, saka voltage yebhatiri inowanzoyerwa kuti ifungidzire huwandu hwebhatiri.Working voltage: musiyano unogona kuitika pakati peiyo yakanaka uye yakaipa electrode yebhatiri kana bhatiri riri kushanda mamiriro, ndiko kuti, kana paine ikozvino inopfuura nepadunhu.Discharge cut-off voltage: iyo voltage yakasvika mushure mekunge bhatiri yazara uye yakabudiswa (kana kubuda kunoramba kuchienderera mberi, kunenge kwakanyanyisa, izvo zvinokuvadza hupenyu nekushanda kwebheteri).Charge cut-off voltage: iyo voltage kana inogara ichichinja kune inogara ichichaja voltage panguva yekuchaja.

Kuchaja uye kuburitsa mwero - buritsa bhatiri neyakagadziriswa ikozvino ye1H, kureva, 1C.Kana iyo lithium bhatiri yakayerwa pa2Ah, ipapo 1C yebhatiri iri 2A uye 3C i6A.

Parallel connection - Kuwanda kwemabhatiri kunogona kuwedzerwa nekuvabatanidza pamwe chete, uye simba = kukwanisa kwebhatiri rimwechete * nhamba yekubatana kwakafanana.Semuenzaniso, Changan 3P4S module, huwandu hwebhatiri imwe chete ndeye 50Ah, ipapo iyo module inokwana = 50 * 3 = 150Ah.

Series yekubatanidza - Iyo voltage yemabhatiri inogona kuwedzerwa nekubatanidza iwo munhevedzano.Voltage = voltage yebhatiri rimwe * nhamba yetambo.Semuenzaniso, Changan 3P4S module, iyo voltage yebhatiri imwe ndeye 3.82V, ipapo iyo module voltage = 3.82 * 4 = 15.28V.

Sechikamu chakakosha mumotokari dzemagetsi, simba re lithium battery modules rinoita basa rinokosha mukuchengetedza uye kusunungura simba remagetsi, kupa simba, nekugadzirisa nekuchengetedza mabheti ebheteri.Vane mimwe misiyano mukuumbwa, basa, hunhu uye mashandisirwo, asi ese ane zvakakosha pakuita uye kuvimbika kwemotokari dzemagetsi.Nekuenderera mberi kwekufambira mberi kwehunyanzvi uye nekuwedzera kwezvishandiso, simba lithium bhatiri modules icharamba ichivandudza uye nekuita mipiro yakakura mukusimudzira uye kufarirwa kwemotokari dzemagetsi.
