Nekufarirwa kwemafambiro enzvimbo dzakasvibira uye pfungwa dzekusimudzira nharaunda, ngoro dzegorofu dzemagetsi dzave nzvimbo yakakosha yekutsigira nzvimbo dzegorofu pasi rese. Se "moyo" wemotokari yese, bhatiri rinosarudza zvakananga kutsungirira, mashandiro uye kuchengetedzeka. Kubva pabhatiri rekutanga re lead-acid kusvika kubhatiri re lithium iron phosphate (LiFePO4) razvino, shanduko yetekinoroji yakavandudza zvakanyanya ruzivo rwekushandiswa uye kushanda zvakanaka kwengoro yegorofu. Chinyorwa chino chichatarisa mabhenefiti eLiFePO4 zvichienzaniswa nemabhatiri ekare e lead-acid maererano nekuchengetedzeka, hupenyu hwekufamba, huwandu hwesimba, kuchinjika kwekupisa uye kumhanya kwekuchaja.
Miganhu yemabhatiri ane lead-acid
Mabhatiri ane lead-acid aimboshandiswa zvakanyanya mumagorofu nekuda kwemutengo wakaderera uye tekinoroji yakakura. Zvisinei, anewo matambudziko akawanda: anorema uye anogara munzvimbo yakawanda, zvichikonzera kudzikira kweruzivo rwekudzora mota yese; ane zvinodiwa zvakanyanya pakugadzirisa uye anoda kuwedzerwa mvura yakasanganiswa nguva nenguva, zvikasadaro anogona kupiswa nesulfur uye kupfupisa hupenyu hwawo. Pamusoro pezvo, hupenyu hwemabhatiri ane lead-acid hunowanzo kuve ka300-500, uye kutsiva kakawanda kunowedzera mutengo wekushandisa kwenguva refu.
Mabhenefiti eLiFePO4 Batteries
Kuchengetedzeka
Mabhatiri eLiFePO4 ane kugadzikana kwakanyanya kwekupisa uye makemikari, haawanzo putika kana kutsva, uye ane hushamwari kune nharaunda uye haana chepfu. Mumamiriro ezvinhu asina kujairika akadai sekupisa kwakanyanya kana short circuit, muganhu wekuchengetedza weLiFePO4 unopfuura zvakanyanya kune mamwe masystem emabhatiri e lithium, uye anogona kupa vimbiso yekushandiswa kwakavimbika kwengoro dzegorofu.
Hupenyu hweKutenderera
Hupenyu hwemabhatiri eLiFePO4 hwakakwira zvakanyanya kupfuura hwemabhatiri ane lead-acid. Kazhinji, anopfuura 2,000, uye zvigadzirwa zvemhando yepamusoro zvinogona kusvika 3,000-5,000 ka, zvinoreva kuti zvinogona kushandiswa nguva dzose kwemakore 5-10 kana zvichinge zvanyatsobuda kamwe chete pazuva. Kusiyana neizvi, kugona kwemabhatiri ane lead-acid kuchaora kusvika pasi pe80% yesimba rekutanga mushure me500 cycles, zvichida kutsiviwa kakawanda, uye zvichiwedzera zvakanyanya mari yekugadzirisa uye kurasikirwa nenguva yekushanda.
Kuwanda kweSimba
Kuwanda kwesimba chiratidzo chakakosha chetekinoroji yebhatiri. Pakugona kumwe chete, huremu hwebhatiri reLiFePO4 hunongova 1/3 yebhatiri re lead-acid, uye vhoriyamu yacho inenge 1/2, izvo zvinoderedza zvakanyanya huremu hwemotokari uye zvinovandudza huwandu hwekutyaira uye mutoro wemotokari. Pamusoro pezvo, kudzika kwakanyanya kwekuburitsa simba (DoD inogona kusvika 80-100%) kunoita kuti mwero wekushandiswa kwesimba ushande zvakanaka uwedzere, nepo DoD yakakwana yebhatiri re lead-acid iri 50% chete, zvichitambisa simba rakawanda.
Kuchinjika kweTembiricha
Munzvimbo ine tembiricha yakaderera, mashandiro ebhatiri rine lead-acid anodzikira zvakanyanya, uye kurasikirwa kwesimba kunogona kusvika kupfuura 50%; nepo bhatiri reLiFePO4 richiri kugona kuchengetedza simba rinodarika 80% uye voltage inobuda pa -10°C, uye tembiricha shoma inobvumirwa yekushanda inogona kusvika -20°C, iyo inogara yakagadzikana munguva yechando kana yemangwanani inotonhora.
Kukwanisa Kuchaja Nekukurumidza
Bhatiri reLiFePO4 rinotsigira mwero wekuchaja wakakwira (kusvika ku0.5C kana kunyange 1C), izvo zvinopfupisa nguva yekumirira kuchaja uye zvinovandudza kushanda zvakanaka kwemotokari. Kusiyana neizvi, mwero wekuchaja unokurudzirwa wemabhatiri ane lead-acid ingori 0.1C–0.2C, uye kazhinji zvinotora maawa 6-8 kuti uchaje zvizere, izvo zvakaoma kusangana nezvinodiwa nekushanda kwe-frequency yakakwira.
Mutengo Wakakwana uye Kukosha
Kunyangwe mari yekutanga yemabhatiri eLiFePO4 yakakwira ne30–50% kupfuura yemabhatiri ane lead-acid, nekuda kwehupenyu hwayo hwakanaka uye hunhu hwayo hushoma hwekuchengetedza, mutengo wekupedzisira unogona kuchengetwa wakafanana kana kutoderera mukati memakore mashanu. Nekufamba kwenguva, LiFePO4 inoderedza kuwanda kwemaawa ekutsiva nekugadzirisa, uye mutengo wese wekuva muridzi (TCO) unounzwa nawo unokwikwidza kupfuura wemabhatiri ane lead-acid.
Mhedziso
Kubva pakuchengetedzeka, hupenyu hwema cycle, huwandu hwesimba, kuchinjika kwekupisa kusvika pakuchaja nekukurumidza, mabhatiri eLiFePO4 aratidza mabhenefiti akazara mukushandiswa kwengoro dzegorofu. Nekugadziriswa kuri kuitwa tekinoroji uye kugadzirwa kukuru, mutengo wemabhatiri eLiFePO4 ucharamba uchiderera. Mune ramangwana, inotarisirwa kuve sosi yemagetsi yengoro dzegorofu dzemagetsi uye kunyange nzvimbo yakakura yeLSV (motokari inomhanya zvishoma), zvichibatsira mashandiro enhandare yegorofu kuti ave anoshanda zvakanyanya, akasvibirira uye agare kwenguva refu.
