Nekuzivikanwa kwekufamba kwakasvibira uye pfungwa dzekusimudzira, ngoro dzegorofu dzemagetsi dzave nzvimbo yakakosha yekutsigira makosi egorofu pasi rese. Sezvo "moyo" wemotokari yose, bhatiri rinotarisa zvakananga kutsungirira, kushanda uye kuchengeteka. Kubva pabhatiri rekutanga rinotungamira-asidhi kusvika kune yazvino bhatiri rethium iron phosphate (LiFePO4), shanduko yetekinoroji yakavandudza zvakanyanya ruzivo rwekushandisa uye kugona kushanda kwengoro yegorofu. Ichi chinyorwa chichatarisa pane zvakanakira LiFePO4 zvichienzaniswa neyakajairwa lead-asidhi mabhatiri maererano nekuchengeteka, kutenderera hupenyu, simba remagetsi, kushanduka kwekushisa uye kukurumidza kuchaja.
Kuganhurirwa kwemabhatiri e-lead-acid
Lead-asidhi mabhatiri aimboshandiswa zvakanyanya mungoro dzegorofu nekuda kwemutengo wakaderera uye tekinoroji yakakura. Zvisinei, vanewo mabhodhoro akawanda: anorema uye anotora nzvimbo yakawanda, zvichiita kuti kuderera kwechiitiko chekutonga kwemotokari yose; vane zvinodiwa zvekuchengetedza zvakanyanya uye vanoda kugara vachiwedzerwa nemvura yakasvibiswa, kana zvisina kudaro ivo vanowanzoita sulfation uye kupfupisa hupenyu hwavo. Pamusoro pezvo, hupenyu hwekutenderera kwemabhatiri e-lead-asidhi hunowanzo kutenderedza 300-500 nguva, uye kazhinji kutsiva kunowedzera mutengo wekushandisa kwenguva refu.
Zvakanakira LiFePO4 Mabhatiri
Safety
Mabhatiri eLiFePO4 ane kugadzikana kwakanyanya kwekushisa uye kwemakemikari, haatani kutonhora kana kupisa, uye ane ushamwari kwezvakatipoteredza uye asina chepfu. Pasi pemamiriro ezvinhu asina kujairika akadai sekushisa kwepamusoro kana kupfupika, muganhu wekuchengetedza weLiFePO4 unopfuura kupfuura weimwe lithium bhatiri masisitimu, uye inogona kupa zvakanyanya kuvimbika kushandiswa zvivimbiso zvegorofu.
Cycle Life
Hupenyu hwekutenderera kweLiFePO4 mabhatiri akakwira zvakanyanya kupfuura iwo e-lead-acid mabhatiri. Kazhinji, inopfuura nguva dze2,000, uye zvigadzirwa zvemhando yepamusoro zvinogona kusvika 3,000-5,000 nguva, zvinoreva kuti inogona kushandiswa nguva dzose kwemakore 5-10 pasi pemamiriro ekubuda kwakadzika kamwe chete pazuva. Kusiyana neizvi, simba remabhatiri e-lead-asidhi richaora kusvika pasi pe80% yehuwandu hwepakutanga mushure memazana mashanu, zvinoda kuchinjwa kakawanda, uye kuwedzera zvakanyanya mari yekugadzirisa uye kurasikirwa kwemaawa.
Energy Density
Simba density chiratidzo chakakosha chebhatiri tekinoroji. Pahuremu hwakafanana, huremu hweLiFePO4 bhatiri hunenge 1/3 chete yeiyo lead-asidi bhatiri, uye vhoriyamu inenge 1/2, iyo inoderedza zvakanyanya huremu hwemotokari uye inovandudza huwandu hwekutyaira uye huwandu hwemotokari. Pamusoro pezvo, kudzika kwepamusoro (DoD inogona kusvika 80-100%) inoita kuti simba rekushandisa rinoshanda riwedzere, nepo DoD yakakwana yebhatiri relead-acid inongosvika makumi mashanu muzana, ichirasa simba rakawanda rinogona kuitika.
Tembiricha Kuchinja
Munzvimbo yakadzika yekushisa, kushanda kwe-lead-acid bhatiri inodonha zvakanyanya, uye kurasikirwa kwesimba kunogona kusvika kupfuura 50%; nepo LiFePO4 bhatiri richiri kugona kuchengetedza kupfuura 80% yesimba uye voltage kubuda pa -10 ° C, uye tembiricha inotenderwa yekushanda inogona kusvika -20 ° C, iyo yakanyanya kugadzikana munguva yechando kana kutonhora kwemangwanani nhandare.
Kukurumidza Kuchaja Kugona
LiFePO4 bhatiri inotsigira yakakwira yekuchaja mwero (kusvika 0.5C kana kunyange 1C), iyo inopfupisa zvakanyanya yekuchaja nguva yekumirira uye inovandudza mashandiro emotokari. Kusiyana neizvi, mwero unokurudzirwa wekuchaja kwemabhatiri e-lead-asidhi ingori 0.1C–0.2C, uye kazhinji zvinotora maawa 6–8 kuti ichajise zvizere, zvinova zvakaoma kuzadzisa zvinodiwa zvekushanda kwepamusoro-soro.
Comprehensive Mutengo uye Kukosha
Kunyange zvazvo kutanga kwekudyara kweLiFePO4 mabhatiri ari 30-50% akakwirira kupfuura ayo e-lead-acid mabhatiri, nekuda kwehupenyu hwayo hwakanaka uye maitiro akaderera ekugadzirisa, mutengo wemari unogona kuchengetwa wakafanana kana kunyange kuderera mukati memakore mashanu. Mukufamba kwenguva, LiFePO4 inoderedza kuwanda kwekutsiviwa nekugadzirisa maawa, uye mari yose yevaridzi (TCO) yakaunzwa nayo inokwikwidza kupfuura iyo yebhatiri ye-lead-acid.
Mhedziso
Kubva pakachengeteka, hupenyu hwekutenderera, huwandu hwesimba, kuchinjika kwekushisa kusvika pakuchaja nekukurumidza, mabhatiri eLiFePO4 aratidza mabhenefiti akazara mumashandisirwo engoro dzegorofu. Nekuenderera mberi kwekugadzirisa tekinoroji uye kugadzirwa kwakakura, mutengo weLiFePO4 mabhatiri ucharamba uchiderera. Mune ramangwana, inotarisirwa kuve iyo yakajairwa magetsi sosi yemagetsi egorofu ngoro uye kunyange yakafara LSV (yakaderera-inomhanya mota) munda, zvichibatsira mashandiro egorofu kuti anyatsoita, akasvibira uye akasimba.
