Unoda kufambisa bhatiri here?

Mhinduro ndeyokuti bhatiri rinoda kushandiswa, asi iri harisi basa remushandisi. Ndakashanyira fekitari iyoyo. Mumazuva ekutanga, mabhatiri e lithium akafamba nenzira dzinotevera:

Iyo electrolyte yerithium bhatiri shell inosanganiswa-kuna-chisimbiso, inochajirwa pamhepo isingaperi, uye yobva yaburitswa. Kutenderera uku kunodzokororwa kakawanda. Iyo electrolyte yakawanda uye inonyorovesa iyo electrode. Iko activation kugona kwakasimba uye inosangana nezvinodiwa. Kugona uku inzira inoshanda. Ongorora bhatiri Kukwanisa, sarudza bhatiri mutsauko wechikamu chechikamu chebhatiri nemabasa akasiyana (unyanzvi), kukwanisa kufanana, nezvimwewo. Iyo inoguma lithium bhatiri ikozvino inoshanda mumaoko evashandisi. Ni-Cd uye Ni-MH mabhatiri anogona zvakare kuvhurwa nekushandurwa kwefekitori. Mamwe mabhatiri anobatidzwa munzvimbo yakavhurika uye anonamwa mushure mekuita. Iyi nzira inogona kuitwa chete nemugadziri webhatiri.

★Iyo inonzi yechipiri activation inogonawo kuitwa. Mushandisi anoedza kuchaja uye kusiya bhatiri kakawanda sezvinobvira kana uchishandisa bhatiri nyowani kekutanga.

● Asi maererano nekuongorora kwangu (pamusoro pemabhatiri e-lithium), nguva yekuchengetedza ye lithiamu mabhatiri ndeye 1-3 mwedzi. Iyo yakadzika yekuchaja uye yakadzika kutenderera kugadzirisa, uye kugona kwayo kufamba chiitiko hachipo zvachose. (Ndine chirevo chekusimbisa bhatiri muchikamu chehurukuro.)

Zvinotora maawa gumi nemaviri kune nyaya nhatu dzekutanga here?

Dambudziko iri rakanyatsoenderana nedambudziko rekuita bhatiri rataurwa pamusoro apa. Tichifunga kuti bhatiri remufekitori rine electrode passivation paruoko rwemushandisi, zvinotora matatu akadzama kuchaja uye kuburitsa madhizaini kuti ivhure bhatiri. Muchokwadi, dambudziko rekuchaja kwakadzika harisi maawa gumi nemaviri ekusachaja. Saka chimwe chinyorwa changu “Mobile Phone Battery Charging Time” inopindura mubvunzo uyu.

Mhinduro haibhadharisi kwemaawa gumi nemaviri.

Mumazuva ekutanga, nekuda kwekudiwa muripo uye kudonhedza kuchaja maitiro enharembozha Ni-MH mabhatiri, zvinogona kutora anenge maawa mashanu kusvika kune yakakwana yekuchaja pachinzvimbo chemaawa gumi nemaviri. Iyo inogara iripo uye inogara ichichaja mabhatiri e lithium mabhatiri anoita kuti yakadzika yekuchaja nguva isingasviki maawa gumi nemaviri.

Semuenzaniso, kune bhatiri ye600ma, isa ikozvino ku 0.01C.6mA), nguva yekubhadhara 1C haipfuuri maminitsi e150, uye wozoisa ikozvino ku0.001 ° C (0.6mA), uye nguva yekuchaja maawa gumi. Izvi zvinogona kunge zviri nekuda kwekururama kwechiridzwa. Izvo hazvigone kuwanikwa nemazvo ikozvino, asi huwandu hunowanikwa kubva ku10 kusvika 0.01 madhigirii chete 0.001 mA, uye kugona kunowanikwa mukutsinhana kweanopfuura maawa manomwe kuri pasi pe1.7/7, iyo isingakoshi kukosha.

Mukuwedzera, kune dzimwe nzira dzekuchaja. Semuyenzaniso, kana pulse kuchaja nzira yelithium bhatiri yasvika 4.2V yekusunga voltage, haizopere padanho razvino, kazhinji 150 maminetsi mushure me100% yakazara chaji. Nharembozha zhinji dzinofambiswa nemapulses.

Vamwe vanhu vaishandisa mbozhanhare dzavo kuflasha mumakore ekutanga, vobva vashandisa chigaro kuchaja kubvuma huwandu hwenharembozha. Iyi nzira yekuongorora haina kungwarira.

Zvakakosha Chiedza chegirini chinoburitswa nechaja hachisi bvunzo yekuchaja chaiyo.

★★ Chengetedza magetsi apo lithiamu bhatiri inobhadharwa (kana kubudiswa) nzira yose mushure mekuona kana lithium battery yakazara.

Chinangwa chaicho chenguva dzose yekudonha kwemagetsi chikamu chezvino ndechekuderedza zvishoma nezvishoma kuwedzera kwemagetsi kunokonzerwa nekuchaja ikozvino kupikisa kwemukati kwebhatiri. Kana iyo ikozvino yakaderera se 0.01c, yakadai se6mA, chigadzirwa chezvino uye kupikisa kwemukati kwebhatiri (kazhinji mukati me200 milliohms) inongova 1mV, uye magetsi panguva ino anogona kuonekwa semagetsi ebhatiri pasina. current.

Chechipiri, iyo referensi voltage yenhare mbozha haina kuenzana nereferensi voltage yechigaro chekuchaja. Iyo nharembozha inofunga kuti bhatiri rakazara uye rinochaja chigaro, nepo chigaro ichifunga kuti bhatiri harina kuzara uye rinoramba richichaja.
