Pfupiso yemamodule ebhatiri

Mamodule emabhatiri chikamu chakakosha chemotokari dzemagetsi. Basa rawo nderekubatanidza masero emabhatiri akawanda pamwe chete kuti aumbe zvese kuti ape simba rakakwana kuti mota dzemagetsi dzishande.

Mamodule emabhatiri zvikamu zvemabhatiri zvinoumbwa nemasero akawanda emabhatiri uye chikamu chakakosha chemotokari dzemagetsi. Basa rawo nderekubatanidza masero akawanda emabhatiri pamwe chete kuti aumbe simba rakakwana remotokari dzemagetsi kana mashandiro ekuchengetedza simba. Mamodule emabhatiri haasi chete sosi yemagetsi emotokari dzemagetsi, asiwo chimwe chezvinhu zvinonyanya kukosha pakuchengetedza simba.

Kuzvarwa kwemamodule ebhatiri

Kubva pamaonero eindasitiri yekugadzira michina, mabhatiri ane sero rimwe chete ane matambudziko akadai sehunhu husina kunaka hwemakanika uye ma interface ekunze asina hushamwari, anosanganisira:

1. Mamiriro ekunze akadai sehukuru nechitarisiko haana kugadzikana, uye achachinja zvakanyanya nekufamba kwenguva kwehupenyu;

2. Kushaikwa kwemuchina wekuisa nekugadzirisa zviri nyore uye zvakavimbika;

3. Kushaikwa kwekubatana kuri nyore kwezvinobuda uye chimiro chekutarisa mamiriro;

4. Dziviriro isina simba yemakanika uye insulation.

Nekuti mabhatiri e-single-cell ane matambudziko ari pamusoro apa, zvakakosha kuwedzera layer kuti uchinje uye ugadzirise, kuitira kuti bhatiri rigone kubatanidzwa nemota yese zviri nyore. Module iyi ine mabhatiri akawanda kusvika gumi kana makumi maviri, ane mamiriro ekunze akagadzikana, ari nyore uye akavimbika emakanika, anobuda, anotarisisa, uye anochengetedza zvakanyanya uye anodzivirira makanika imhedzisiro yesarudzo iyi yechisikigo.

Module yakajairika iripo inogadzirisa matambudziko akasiyana-siyana emabhatiri uye ine mabhenefiti makuru anotevera:

1. Inogona kuita kuti kugadzirwa kwega kuve nyore uye ine kugona kukuru kwekugadzira, uye mhando yechigadzirwa nemutengo wekugadzira zviri nyore kudzora;

2. Inogona kuumba mwero wepamusoro wekuenzanisa, izvo zvinobatsira kuderedza zvakanyanya mari yekugadzira uye kuvandudza kushanda zvakanaka kwekugadzira; ma interfaces akajairwa uye zvirevo zvinobatsira kukwikwidzana kwakazara kwemusika uye kusarudzwa kwemativi maviri, uye kuchengetedza kushanda kuri nani kwekushandiswa kwecascade;

3. Kuvimbika kwakanaka, izvo zvinogona kupa dziviriro yakanaka yemakanika uye insulation yemabhatiri muhupenyu hwese;

4. Mari shoma yezvinhu zvisina kugadzirwa haizonyanyi kumanikidza pamutengo wekupedzisira wekugadzira sisitimu yemagetsi;

5. Mutengo wepasi weyuniti inochengetedzwa idiki, izvo zvine mhedzisiro yakakura pakuderedza mari yekutengeswa mushure mekutengesa.

Maumbirwo emodule yebhatiri

Maumbirwo emodule yebhatiri anowanzo sanganisira bhatiri, sisitimu yekutarisira bhatiri, bhokisi rebhatiri, chinongedzo chebhatiri nezvimwe zvikamu. Bhatiri ndiro chinhu chakakosha chemodule yebhatiri. Rinoumbwa nemayuniti akawanda ebhatiri, kazhinji bhatiri re lithium-ion, rine hunhu hwesimba rakawanda, mwero wakaderera wekuzviburitsa uye hupenyu hurefu hwebasa.

Sisitimu yekugadzirisa mabhatiri iripo kuti ive nechokwadi chekuti bhatiri rakachengeteka, rakavimbika uye rinogara kwenguva refu. Mabasa ayo makuru anosanganisira kutarisa mamiriro ebhatiri, kudzora tembiricha yebhatiri, kudzivirira bhatiri kudzvanya/kuburitsa mvura yakawanda, nezvimwewo.

Bhokisi rebhatiri igoko rekunze remodule yebhatiri, iro rinoshandiswa kuchengetedza module yebhatiri kubva kunharaunda yekunze. Bhokisi rebhatiri rinowanzogadzirwa nesimbi kana purasitiki, rinodzivirira ngura, rinodzivirira moto, rinodzivirira kuputika nezvimwe zvinhu.

Chinobatanidza bhatiri chinhu chinobatanidza mabhatiri akawanda kuita chinhu chimwe chete. Chinowanzogadzirwa nezvinhu zvemhangura, chine simba rakanaka rekufambisa mvura, chinodzivirira kupera uye chinodzivirira ngura.

Zviratidzo zvekushanda kwemodule yebhatiri

Kuramba kwemukati kunoreva kuramba kwemagetsi ari kuyerera nebhatiri kana bhatiri richishanda, izvo zvinokanganiswa nezvinhu zvakaita sezvinhu zvebhatiri, maitiro ekugadzira uye chimiro chebhatiri. Yakakamurwa kuva ohmic internal resistance uye polarization internal resistance. Ohmic internal resistance inoumbwa nekuramba kwekubatana kwezvinhu zve electrode, electrolytes, diaphragms nezvimwe zvikamu zvakasiyana; polarization internal resistance inokonzerwa ne electrochemical polarization uye concentration difference polarization.

Simba rakati - simba rebhatiri pahuwandu kana huremu hweyuniti.

Kushanda zvakanaka kwekuchaja nekuburitsa magetsi - chiyero chekuti simba remagetsi rinoshandiswa nebhatiri panguva yekuchaja rinoshandurwa sei kuita simba remakemikari rinogona kuchengetwa nebhatiri.

Voltage - musiyano unowanikwa pakati pemaerekitironi akanaka neasina kunaka ebhatiri.

Voltage yedunhu rakavhurika: voltage yebhatiri kana pasina dunhu rekunze kana mutoro wekunze wakabatana. Voltage yedunhu rakavhurika ine hukama hwakati wandei nekugona kwasara kwebhatiri, saka voltage yebhatiri inowanzo kuyerwa kuti iongorore kugona kwebhatiri. Voltage yekushanda: musiyano uripo pakati pemaelectrode akanaka neasina kunaka ebhatiri kana bhatiri riri kushanda, ndiko kuti, kana paine magetsi anopfuura nemudunhu. Voltage yekubvisa magetsi: voltage inosvika mushure mekunge bhatiri rachajwa zvizere uye raburitswa (kana kuburitsa magetsi kukaramba kuripo, richaburitswa zvakanyanya, izvo zvinokanganisa hupenyu nekushanda kwebhatiri). Voltage yekubvisa magetsi: voltage kana magetsi asingaperi achichinja kuita magetsi asingaperi panguva yekuchaja.

Kuchaja uye kuburitsa simba - buritsa simba remagetsi ne1H, kureva 1C. Kana bhatiri re lithium rakaiswa pa2Ah, saka 1C yebhatiri i2A uye 3C i6A.

Kubatana kwakafanana – Kugona kwemabhatiri kunogona kuwedzerwa nekubatanidza pamwe chete, uye kugona = kugona kwebhatiri rimwe chete * huwandu hwekubatana kwakafanana. Semuenzaniso, module yeChangan 3P4S, kugona kwebhatiri rimwe chete i50Ah, uye kugona kwemodule = 50*3 = 150Ah.

Kubatana kwemabhatiri - Voltage yemabhatiri inogona kuwedzerwa nekubatanidza mu series. Voltage = voltage yebhatiri rimwe chete * nhamba yetambo. Semuenzaniso, Changan 3P4S module, voltage yebhatiri rimwe chete i3.82V, ipapo voltage yemodule = 3.82*4 = 15.28V.

Sechinhu chakakosha mumotokari dzemagetsi, mamodule emabhatiri emagetsi e-lithium anoita basa guru mukuchengetedza nekuburitsa simba remagetsi, kupa simba, uye kutarisira nekudzivirira mapaketi emabhatiri. Ane misiyano yakati wandei mukuumbwa, mashandiro, hunhu uye mashandisirwo, asi ese ane chekuita nekushanda uye kuvimbika kwemotokari dzemagetsi. Nekufambira mberi kuri kuramba kuchiita tekinoroji uye kuwedzera kwemashandisirwo, mamodule emabhatiri emagetsi e-lithium acharamba achikura uye achipa mipiro yakakura mukusimudzirwa nekufambiswa kwemotokari dzemagetsi.
