Zomwe Zimapangitsa Mabatire a Lithium Anzeru?

M'dziko la mabatire, pali mabatire omwe ali ndi mayendedwe owunikira kenako pali mabatire opanda.Lithium imatengedwa kuti ndi batire yanzeru chifukwa imakhala ndi bolodi losindikizidwa lomwe limayang'anira magwiridwe antchito a batri ya lithiamu.Kumbali inayi, batire ya asidi yosindikizidwa yosindikizidwa ilibe ulamuliro uliwonse kuti ikwaniritse bwino ntchito yake.

Mu a Smart lithiamu batirepali magawo atatu owongolera.Gawo loyamba la kuwongolera ndikusintha kosavuta komwe kumangowonjezera ma voltages a ma cell.Mulingo wachiwiri wowongolera ndi gawo lodzitchinjiriza (PCM) lomwe limateteza ma cell a ma voliyumu apamwamba / otsika ndi mafunde pamalipiro ndi kutulutsa.Mulingo wachitatu wowongolera ndi kasamalidwe ka batri (BMS).BMS ili ndi kuthekera konse kwa gawo lozungulira komanso gawo loteteza dera koma ili ndi magwiridwe antchito owonjezera momwe batire imagwirira ntchito pa moyo wake wonse (monga kuyang'anira momwe ndalama zilili komanso thanzi).

LITHIUM BALANCING CIRCUIT

Mu batire yokhala ndi tchipisi chowongolera, chip chimangoyezera kuchuluka kwa ma cell omwe ali mu batire pomwe ikulipira.Batire imaonedwa kuti ndi yoyenera pamene ma voltages onse a selo ali mkati mwa kulolerana pang'ono kwa wina ndi mzake.Pali mitundu iwiri ya kulinganiza, yogwira ntchito ndi yongokhala.Kusanja bwino kumachitika pogwiritsa ntchito ma cell okhala ndi ma voltages okwera kuti azilipiritsa ma cell okhala ndi ma voltages otsika potero amachepetsa kusiyana kwa voteji pakati pa ma cell mpaka ma cell onse afananize bwino ndipo batire ili ndi charger yokwanira.Kusanjikiza kosalekeza, komwe kumagwiritsidwa ntchito pamabatire onse a Power Sonic lithiamu, ndi pamene selo lililonse lili ndi chopinga chofananira chomwe chimayatsidwa pamene magetsi a cell ali pamwamba pa chigawo.Izi zimachepetsa kuchuluka kwa magetsi m'maselo omwe ali ndi magetsi okwera kwambiri zomwe zimapangitsa kuti ma cell ena agwire.

N'chifukwa chiyani kulinganiza kwa maselo kuli kofunika?M'mabatire a lithiamu, pamene selo lotsika kwambiri lamagetsi likugunda mphamvu yamagetsi yodulidwa, idzatseka batire lonse.Izi zikhoza kutanthauza kuti maselo ena ali ndi mphamvu zosagwiritsidwa ntchito.Momwemonso, ngati ma cellwo sali bwino pochajisa, kulipiritsa kumasokonekera pomwe selo lomwe lili ndi voteji lalitali kwambiri lifika pamagetsi oduka ndipo ma cell onse sangamalizidwe mokwanira.

Choyipa chake ndi chiyani pamenepo?Kuchapira nthawi zonse ndi kutulutsa batire yosalinganiza kumachepetsa mphamvu ya batire pakapita nthawi.Izi zikutanthawuzanso kuti ma cell ena adzayimitsidwa kwathunthu, ndipo ena sadzatero, zomwe zimapangitsa batire lomwe silingafike ku 100% State of Charge.

Chiphunzitso chake ndi chakuti maselo oyenerera onse amatuluka pa mlingo wofanana, choncho amadulidwa pamagetsi omwewo.Izi sizowona nthawi zonse, chifukwa chake kukhala ndi chip chowongolera kumawonetsetsa kuti potchaja, ma cell a batri amatha kufananizidwa mokwanira kuti ateteze mphamvu ya batriyo komanso kuti ikhale yokwanira.

LITHIUM PROTECTIVE CIRCUIT MODULE

Protective Circuit Module ili ndi dera loyendera bwino komanso ma circuit ena omwe amayendetsa batire poteteza kuti isamangidwe komanso kuti isathe.Imachita izi poyang'anira zamakono, ma voltages, ndi kutentha panthawi yamalipiro ndi kutulutsa ndikuziyerekeza ndi malire omwe anakonzedweratu.Ngati ma cell a batri agunda limodzi la malirewo, batire imazimitsa kuyitanitsa kapena kutulutsa molingana mpaka njira yotulutsirayo yakwaniritsidwa.

Pali njira zingapo zoyatsiranso kuyitanitsa kapena kutulutsa chitetezo chikayimitsidwa.Yoyamba imatengera nthawi, pomwe chowerengera chimawerengera nthawi yochepa (mwachitsanzo, masekondi 30) kenako ndikutulutsa chitetezo.Chowerengera ichi chikhoza kusiyanasiyana pachitetezo chilichonse ndipo ndi chitetezo chamlingo umodzi.

Yachiwiri ndiyotengera mtengo, pomwe mtengo uyenera kutsika pansi pamlingo kuti utulutsidwe.Mwachitsanzo, ma voltages onse ayenera kutsika pansi pa 3.6 volts pa selo kuti chitetezo chowonjezera chitulutsidwe.Izi zikhoza kuchitika mwamsanga pamene chikhalidwe chomasulidwa chikakwaniritsidwa.Zitha kuchitikanso pakatha nthawi yodziwikiratu.Mwachitsanzo, ma voltages onse ayenera kutsika pansi pa 3.6 volts pa selo kuti atetezeke mopitirira malire ndipo ayenera kukhala pansi pa malirewo kwa masekondi a 6 PCM isanatulutse chitetezo.

Chachitatu ndi ntchito yokhazikitsidwa, pomwe chinthu chiyenera kuchitidwa kuti atulutse chitetezo.Mwachitsanzo, kuchitapo kanthu kungakhale kuchotsa katunduyo kapena kulipiritsa.Mofanana ndi kumasulidwa kozikidwa pa mtengo, kumasulidwa uku kungathenso kuchitika nthawi yomweyo kapena kutengera nthawi.Izi zitha kutanthauza kuti katunduyo ayenera kuchotsedwa mu batire kwa masekondi 30 chitetezo chisanatulutsidwe.Kuphatikiza pa nthawi ndi mtengo kapena ntchito ndi zotulutsidwa zotengera nthawi, ndikofunikira kuzindikira kuti njira zotulutsirazi zitha kuchitika muzophatikiza zina.Mwachitsanzo, voteji yotulutsa mopitilira muyeso imatha kukhala ma cell atsika pansi pa 2.5 volts koma kulipiritsa kwa masekondi 10 kumafunika kuti mufike pamagetsi amenewo.Kutulutsidwa kwamtunduwu kumakhudza mitundu yonse itatu ya zotulutsidwa.

Timamvetsetsa kuti pali zinthu zambiri zomwe zimatsogolera pakusankha zabwino kwambiri lithiamu batire, ndipo akatswiri athu ali pano kuti atithandize.Ngati muli ndi mafunso owonjezera okhudza kusankha batire yoyenera pa pulogalamu yanu, chonde khalani omasuka kulumikizana ndi mmodzi wa akatswiri athu lero.
