Ice Bucket Dambudziko! Ko tembiricha yakaderera inoderedza huwandu hwebhatiri here?

Mumabhuku ane mifananidzo anoshandiswa nemidziyo yakawanda yedhijitari, tinogona kuona tembiricha yekushandisa yechigadzirwa, mazhinji acho ari 10 degrees Celsius uye 40 degrees Celsius. Isu tinoziva kuti lithium bhatiri yakachengeteka kushanda panguva yekuchaja uye kupisa, uye yakaderera tembiricha electrolyte yakaiswa mukupisa kwakanyanya uye yakaderera tembiricha mamiriro Kushanda kwemukati kwe lithium mabhatiri kwakaderera, kunokanganisa kushandiswa kwevashandisi, uye kunyange kukonzeresa- kutadza kwekushisa kwebhatiri.

Kana ukashandisa nharembozha dzakawanda kana mabhatiri muchando chekuchamhembe, unogona kuona kuti kana tembiricha yadzikira, kushanda kwebhatiri kunokanganisa, uye kunyange zvigadzirwa zvemagetsi hazvigone kuvhurwa. Ngatitarisei kushanda kwebhatiri pane tembiricha yakaderera.

Bhatiri rinonyanya kukosha ratinoshandisa ikozvino lithium bhatiri. Mune dzidziso, iyo tembiricha mhedzisiro yemabhatiri eti lithium yakangofanana. Kuti tienzanise kukanganisa kwekushisa kwepasi zvakanyanya intuitively, takasarudza bvunzo yekuita iyo inogona kuverengera bhangi remagetsi.

Portable power supply yakatarisana ne low tembiricha bvunzo

Tichifunga nezvemabhatiri akasiyana anoshandiswa munharembozha dzemagetsi, isu takamisawo maviri anowanzo shandiswa lithium bhatiri nhare dzemagetsi ekutora data sampling, kusanganisira soft pack lithium mabhatiri (anowanzo zivikanwa).

Bhatiri rine hupenyu hurefu hwebasa pane tembiricha yekamuri

Kuti tifambise kunotevera kuenzanisa kwekuenzanisa, isu tinotanga kuyedza kuburitsa mashandiro eiyo nharembozha yemagetsi pakudziya kwekamuri. Se data yeboka rekutonga, tembiricha yekuburitsa nharaunda yeboka rekutonga i30 ℃.

Ndapota cherechedza kuti tiri pano kuti tienzanise kushanda kwebhatiri rimwe chete pakupisa kwakasiyana. Mabhangi emagetsi emabhatiri akasiyana atakaedza haasati agadziriswa. Nokudaro, marudzi maviri aya emasero haana kuenzaniswa.

Discharge curve ye soft-clad lithium bhatiri pane tembiricha yekamuri

Zvinogona kuoneka kuti soft-pack lithium bhatiri yakagadzikana pakamuri tembiricha ye30 ° C, iyo yakazara voltage inenge 4.95V, uye referensi yekubuda simba ndeye 35.1 watt-maawa.

18650 bhatiri mukamuri tembiricha yekuburitsa curve

Bhatiri re18650 rine kushanduka kushoma patembiricha yekamuri, iyo voltage yakakwira kupfuura 4.9V, uye kugadzikana kwakanaka. Iyo referensi yekubuda simba ndeye 29.6 watt-maawa.

mobile power pakamuri tembiricha

Zvinogona kuoneka kuti ese ari maviri ane mashandiro akanaka pane tembiricha yekamuri, uye kubuda kwakadzikama pakudziya kwekamuri kunogona kupawo yakanakisa hupenyu hwebhatiri vimbiso. Ehe, uku ndikowo kuronga uye kutsanangurwa kwekushandisa kwemagetsi enhare nemabhatiri. Nhanho inotevera ndeyekuyedza kubuda kwebhatiri pakudziya kwakaderera.

freezing point ichidimbu chekeke

0 ℃ ndiyo tembiricha yakajairwa yemusanganiswa wemvura yechando, uye zvakare tembiricha inofanirwa kucherechedzwa chando chisati chasvika kuchamhembe kwenyika yangu. Takatanga kuyedza maitiro ekuburitsa emagetsi enhare pa 0 ° C.

Mvura inoyerera iri mumusanganiswa wemvura yechando

Kunyangwe tembiricha ye0 ℃ iri tembiricha yakadzika, ichiri mukati metembiricha yekushanda yebhatiri, uye bhatiri rinofanirwa kushanda zvakajairika. Isu tinoisa nharembozha musanganiswa wemvura yechando, kuburitsa mushure mekudzikama tembiricha, wedzera ice kuchengetedza tembiricha, uye pakupedzisira kutumira data rekuburitsa.

Iyo yekuburitsa curve ye soft-clad lithium bhatiri pane tembiricha yekamuri uye zero nharaunda

Zvinogona kuonekwa kubva pakubuda kwemhepo kuti kubuda kwevheti ye-soft-pack lithium bhatiri yakashanduka zvikuru, mavhiriji ose uye nguva yekubuda yakaderedzwa, uye simba rekubuda rakaderedzwa kusvika ku32.1 watt-maawa.

18650 bhatiri mukamuri tembiricha uye zero nharaunda discharge curve

Iyo 18650 discharge curve haina kunyanya kukanganiswa, asi yekutanga voltage inowedzera, asi simba rinonyanya kukanganiswa, kusvika ku16.8 Wh.

Inogona kuwanikwa kuti pa 0 ° C, bhatiri haina kunyanya kukanganiswa uye mhepo yekushandura magetsi haisi yakakura, uye inogona kupiwa kumushandisi kuti ishandiswe nguva dzose. Munzvimbo yakadai, bhatiri remagetsi harifanirwe kuchengetedzwa zvakanyanya.

Zvinobuda munzvimbo dzinotonhora zvinokanganiswa

minus 20 degrees Celsius inzvimbo inotonhora zvakanyanya, uye zviitiko zvekunze zvakaderedzwa zvakanyanya, asi kushanda kwebhatiri kwakakoshawo zvakanyanya munzvimbo iyi yakaoma. Iyi ndiyo tembiricha yakaderera yatakaedza.

Iyo yekuburitsa curve ye soft-clad lithium bhatiri pane tembiricha dzakasiyana

Pa -20 ° C, kubuda kweiyo nyoro-clad lithium bhatiri zviri pachena kukanganiswa, uye kubuda curve kunoratidzika sezviri jitter.
