Kuchaja bhatiri uye kuyedza kubudainzira yekuedza inoshandiswa kuongorora zviratidzo zvakakosha zvakadai sekushanda kwebhatiri, hupenyu, uye kuchaja uye kubuda zvakanaka. Kuburikidza nekuchaja uye kuyedzwa kwekuburitsa, tinogona kunzwisisa mashandiro ebhatiri pasi pemamiriro akasiyana ekushanda uye kuderedzwa kwayo mukushandiswa kwenguva refu. Tevere, tevera heltec kuti udzidze nezve bhatiri kuchaja uye kuyedza kubuda.
Battery Charge uye Discharge Testing Gadziriro:
Test equipment: Professionalkuchaja uye kuburitsa bvunzo zviridzwazvinodiwa, zvinosanganisira mabhatiri anoedza, machaja, zvinoburitsa, uye masisitimu ekutema data. Midziyo iyi inogona kunyatso kudzora kuchaja ikozvino, voltage, uye kubuda ikozvino. Yedza bhatiri: Sarudza bhatiri kuti riongororwe uye uone kuti bhatiri riri muchimiro chisina chaji kana chakazara. Mamiriro ekunze: Tembiricha ine simba guru pakuita kwebhatiri. Muedzo unofanirwa kuitwa pane yakatarwa tembiricha yepakati, kazhinji 25 ° C.
Test method:
Constant current charge and discharge test: Shandisa inogara iripo kubhadharisa uye kuburitsa bhatiri, iro rinogona kuyera huwandu hwebhatiri, kuchaja uye kuburitsa kunyatsoshanda uye kutenderera hupenyu. Paunenge uchichaja, shandisa inogara iripo kubhadharisa kumuganhu wepamusoro webhatiri, senge lithium bhatiri kusvika 4.2V; paunenge uchiburitsa, shandisa inogara iripo kuburitsa kune yakaderera muganhu voltage, senge lithium bhatiri kusvika 2.5V.
Constant voltage charge test: Inowanzo shandiswa kune lithium bhatiri kuchaja kudzivirira kuwandisa. Chekutanga kuchaja neanogara aripo, uye mushure mekusvika payakagadzika voltage, ramba uchichaja pane iyi voltage kusvika ikozvino yadonha kune preset kukosha.
Constant power discharge test: Bvisa bhatiri pane simba rinogara richiripo kusvika iyo shoma voltage yebhatiri yasvika, kuitira kuti uedze kubuda kwebhatiri pasi pesimba risingaperi.
Cycle life test:Dzokorora kuchaja uye kuburitsa kutenderera kusvikira huwandu hwebhatiri hwadonha kune imwe kukosha, senge 80% yesimba rekutanga, kuyedza hupenyu hwebhatiri. Izvo zvinodikanwa kuseta mamiriro ekugumisira ehuwandu hwekuchaja uye kuburitsa matenderera kana kuparara kwesimba, uye kurekodha shanduko yehukwanisi hwega rega rega.
Fast charge uye discharge test:Shandisa zvazvino zvekuchaja nekukasira kuyedza kumhanyisa kuchaja uye kugona kubuda uye kuora kwekuita kwebhatiri. Inobhadhara nokukurumidza nepamusoro-soro, uye kana iyo yakagadziriswa yasvika, inokurumidza kuchinja kune nzira yekubuda.
Test zviratidzo:
Kugonazvinoreva huwandu hwemagetsi anogona kuburitswa nebhatiri mune mamwe mamiriro ekubuda, kazhinji mumaawa-ampere (Ah) kana kilowatt-maawa (kWh), iyo inotaridza zvakananga simba rekuchengetedza simba rebhatiri.
Kuramba mukati:Kupokana kunosangana kana ikozvino ichiyerera nemubhatiri, mumamiliohms (mΩ), kusanganisira ohmic yemukati kuramba uye polarization yemukati kuramba, iyo inokanganisa kuchaja kwebhatiri uye kuburitsa kushanda zvakanaka, chizvarwa chekupisa, uye hupenyu.
Energy density:yakakamurwa kuita huremu hwesimba uye vhoriyamu simba density, izvo zvichiratidza simba iro bhatiri rinogona kubuda pahuremu hweyuniti kana pavhoriyamu yeyuniti, ine mayuniti ekutanga eWh/kg uye Wh/L, zvichiteerana, zvichikanganisa chinhambwe chekutyaira kwemotokari dzemagetsi uye mimwe michina uye dhizaini isina kuremerwa yemotokari yese.
Charge uye discharge rate:Inoratidza chiyero chekuchaja kwebhatiri uye kubuda ikozvino, muC, ichiratidza kugona kwebhatiri kuchaja nekubuda nekukurumidza.
Battery Charge uye Discharge Test zvishandiso:
Bhatiri kuchaja uye discharge testerinogona kuita yakadzama kuchaja uye yekuburitsa bvunzo pamhando dzakasiyana dzemabhatiri, inobatanidza yakakwira-chaiyo kuyerwa, kutonga nehungwaru uye mabasa ekuongorora data, inogona kutevedzera chaiwo mamiriro ekushanda, uye kunyatsoongorora zvakakwana kugona kwebhatiri, kuramba kwemukati, kuchaja uye kuburitsa kushanda zvakanaka, kutenderera hupenyu nezvimwe. zviratidzo.
Heltec ine zvakasiyana-siyana zvebhatiri kuchaja uye discharge test equipment, inokwanisika uye yakanaka mhando, unogona kusarudza chigadzirwa chinokukodzera iwe zvinoenderana nebhatiri rako razvino voltage, nezvimwewo, kuti upe yakanaka data monitoring yebhatiri rako.
