Ko Lithium-ion Battery Charge and Discharge sei?

Lithium-ion mabhatiri anofarirwa nekuda kwehuwandu hwesimba rawo, hupenyu hurefu hwekutenderera, uye mwero wakaderera wekuzviburitsa. Kunzwisisa kuti mabhatiri aya anoshanda sei kwakakosha.

Lithium-ion Battery Zvikamu

Zvinhu zvakakosha zvebhatiri ye lithium-ion zvinosanganisira anode, cathode, electrolyte, uye separator. Zvinhu izvi zvinoshanda pamwechete kuchengetedza uye kuburitsa simba nemazvo. Iyo anode inowanzogadzirwa negraphite, nepo cathode ine lithium simbi oxide. Iyo electrolyte ndeye lithium munyu mhinduro mune organic solvent, uye inoparadzanisa iine membrane yakatetepa inodzivirira mapfupi maseketi nekuchengeta anode uye cathode zvakaparadzana.

Charge uye Discharge Process

Iyo yekuchaja uye yekuburitsa mabhatiri e-lithium-ion yakakosha pakushanda kwavo. Aya maitiro anosanganisira kufamba kwe lithium ions pakati peanode uye cathode kuburikidza ne electrolyte.

The Charging Process

Kana lithium-ion bhatiri ichichaja, lithium ions inofamba kubva pacathode ichienda kune anode. Kufamba uku kunoitika nekuti simba remagetsi rekunze, rinoisa voltage pamaterminal ebhatiri. Iyi voltage inotyaira lithium ions kuburikidza ne electrolyte uye kupinda muanode, kwainochengeterwa. Maitiro ekuchaja anogona kukamurwa kuita matanho makuru maviri: iyo inogara iripo (CC) chikamu uye inogara voltage (CV) chikamu.

Munguva yeCC chikamu, ikozvino yakadzikama inopihwa kubhatiri, zvichiita kuti voltage iwedzere zvishoma nezvishoma. Kamwe bhatiri rasvika parinogumira voltage muganho, charger inochinja kune CV chikamu. Muchikamu ichi, voltage inobatwa nguva dzose, uye ikozvino inoderera zvishoma nezvishoma kusvikira yasvika pakukosha kushoma. Panguva ino, bhatiri rakazara zvakakwana.

The Discharging Process

Kuburitsa lithium-ion bhatiri kunosanganisira reverse process, uko lithium ions inofamba kubva kune anode ichidzokera kucathode. Kana bhatiri rakabatana nemudziyo, mudziyo unodhonza simba remagetsi kubva mubhatiri. Izvi zvinokonzera kuti lithium ions ibve pane anode uye ifambe kuburikidza ne electrolyte kusvika kune cathode, ichigadzira magetsi emagetsi anopa simba.

Magadzirirwo emakemikari panguva yekubuda anonyanya kupesana neaya panguva yekuchaja. Iyo lithium ions inopindirana (ipinza) mu cathode zvinhu, nepo maerekitironi achiyerera nepakati rekunze redunhu, achipa simba kune yakabatana mudziyo.

Aya maitirwo anoratidza kufambiswa kwelithium ion uye kuyerera kunoenderana kwemaerekitironi, ayo akakosha pakushanda kwebhatiri.

Lithium-ion Battery Hunhu

Lithium-ion mabhatiri anozivikanwa nehunhu hwawo hwakadai, senge yakakwira simba density, yakaderera kuzviburitsa, uye hupenyu hurefu hwekutenderera. Aya hunhu anoita kuti ave akakwana kune zvikumbiro apo simba rinogara kwenguva refu rakakosha. Akawanda makiyi ekuita metrics anoshandiswa kuongorora lithium-ion mabhatiri:

Energy Density: Inoyera huwandu hwesimba rakachengetwa muvhoriyamu yakapihwa kana huremu.

Cycle Hupenyu: Inoratidza huwandu hwekuchaja-kuburitsa madhizaini bhatiri rinogona kuitika risati radzikira zvakanyanya.

C-rate: Inotsanangura muyero wekuchajwa kana kubuda kwebhatiri zvichienderana nehukuru hwayo.

Kukosha Kwekutarisa Charge uye Discharge

Kutarisa kubhadharisa uye kuburitsa mabhatiri e-lithium-ion mabhatiri kwakakosha kuti uve nechokwadi chekugara kwavo kwenguva refu uye kuchengetedzeka. Kuwedzeresa kana kuburitsa kwakadzika kunogona kukonzera kukuvadzwa kwebhatiri, kudzikiswa kwehuwandu, uye kunyangwe njodzi dzekuchengetedza sekumhanya kwekupisa. Kunyatsoongorora kunobatsira kuchengetedza kushanda kwakakwana uye kuwedzera hupenyu hwebhatiri. Yepamberi yekutarisisa mhinduro senge DFUN Centralized Battery Monitoring Cloud System inoita basa rakakosha mukutarisa uye kutonga kubhadharisa uye kuburitsa maitiro. Iyo sisitimu inorekodha iyo yakazara yekuchaja uye yekuburitsa mamiriro, inoverengera iyo chaiyo huwandu, uye inova nechokwadi chekuti iyo yakazara bhatiri paki inoramba ichishanda uye yakachengeteka kushandisa.
