Lifiyamu chitsulo mankwala batire: makhalidwe, ntchito

zida zamakono tsiku lililonse ndi kukhala zovuta wamphamvu. Mkulu mfundo luso kukakamira mkulu mabatire kuti tsopano muyenera kuphatikiza ntchito yapamwamba, mphamvu Mwachangu, ndipo ndi kuchuluka ya magetsi.

Mawu oyamba a mitundu yatsopano ya ulimi magetsi zipangizo, mathamangitsidwe kwa ndondomekoyi - zonsezi kumawonjezera atawalamula magetsi, ndipo mabatire ano sangathenso nthawi kukakumana nawo. Kuti athetse vutoli, opanga asankha bwino luso lifiyamu-ion. Choncho anabadwa lifiyamu chitsulo mankwala batire (LiFePO4), lomwe ndi mbeu maganizo a mabatire Li-ion.

nkhani za m'mbiri

LiFePO4, kapena LFP, - mchere zachilengedwe olivine banja, anali woyamba anatulukira mu 1996 asayansi ku University of Texas, John Goodenough, amene anali kufunafuna njira zopititsira patsogolo Li-ion magwero mphamvu. Lodziwika n'chakuti mchere ali ndi kawopsedwe m'munsi ndi apamwamba matenthedwe bata kuposa chilichonse kudziwika panthawi maelekitirodi.

Kuwonjezera izo anakumana mu chilengedwe, ndipo anali ndi mtengo wotsika. The drawback waukulu maelekitirodi pa maziko a LiFePO4 ina yaing'ono mphamvu ya magetsi, nchifukwa chake lifiyamu batire chitsulo mankwala watha kuphunzira.

Research umenewu anali adapitiriza mu 2003 pa Institute of Technology Massachusetts. A gulu la asayansi ntchito pa chilengedwe cha batire wachibadidwe watsopano kuti akhale wogwirizira kwa patsogolo kwambiri pa mabatire nthawi, Li-ion. polojekiti chidwi makampani akuluakulu monga LG ndi Qualcomm, amene anabweretsa zikamera wa batire ndi zinthu LiFePO4 cathode.

LiFePO4 batire pamaziko a

Mtundu wa mabatire amagwiritsa ntchito luso yomweyo kutulutsa magetsi, ndipo mwachizolowezi maselo lifiyamu-ion kwa ife. Komabe, pali kusiyana kwambiri pakati pawo. Choyamba, ndi kugwiritsa ntchito mtundu yakeyake BMS - kasamalidwe dongosolo amateteza batire magetsi kuchokera overcharging ndi kumaliseche kwambiri, bwino kwake ndipo zimapangitsa gwero mphamvu wolimba kwambiri.

Kachiwiri, LiFePO4, mosiyana LiCoO2, si poizoni. Zimenezi analola kupewa mavuto ena amagwirizana ndi kuwonongeka kwa malo. Makamaka kuchepetsa mpweya wa cobalt chifukwa zosayenera kutaya mabatire.

Pomaliza, chifukwa chosowa mfundo logwirizana zinthu LFP ndi nyimbo osiyana mankhwala, zomwe zimabweretsa zitsanzo kusintha Magwiridwe pa osiyanasiyana. Komanso, zonsezi mphamvu yokonza kovuta zizichitidwa zoletsedwa ndi malamulo.

makhalidwe luso

Akuti lifiyamu chitsulo mankwala batire 48 volts, volts 36 60 volts amapangidwa ndi sequentially interconnecting maselo limodzi, chifukwa voteji pazipita mu LFP-gawo limodzi mwina upambana 3,65 V. Choncho, ntchito iliyonse batire mulole kwambiri amasiyana mzake - izo zidalira pa msonkhano ndi makamaka mipweya.

Yoganizira Magwiridwe azipereka mtengo mwadzina la selo mmodzi.

Kuzindikira bwino za angathe mukachipinda munthu mu batire wakhala anafika Everexceed. Lifiyamu chitsulo mankwala batire Everexceed amasiyana ndi moyo wautali. Onse angathe kupirira mpaka 4 zikwi m'zinthu Lamulira-kumaliseche. Imfa ya mphamvu kuti 20%, ndi kubwezeretsa yosungirako mphamvu kumachitika mu mphindi 12. Popeza ichi, tinganene kuti Everexceed mabatire ndi m'modzi wa ophunzira bwino za LFP-zinthu.

Ubwino ndi Kuipa

The mwayi waukulu kuti mu kuwala yabwino likusonyeza lifiyamu chitsulo mankwala batire, mwa oimira ena a CRA, ndi moyo wautali. Amenewa amafotokozera ndi amatha kupirira oposa 3 zikwi mlandu-kumaliseche m'zinthu pa mlingo mphamvu akutsikira 30%, ndipo oposa 2 zikwi - .. Ngati amagwa 20%. Chifukwa cha ichi pafupifupi moyo batire pafupifupi zaka 7.

Khola nawuza panopa ndi zofunika mwayi wachiwiri wa LFP-zinthu. The linanena bungwe voteji amakhalabe wofanana 3.2 V mpaka mtengo ndi kutopa kotheratu. Izi zimatithandiza Kulumikizana, kuchotsa kufunika owongolera voteji.

Apamwamba pachimake apano - wachitatu wa awo mwayi. Mbali imeneyi zimathandiza batire kuwapatsa mphamvu pazipita ngakhale pa otsika kutentha kwambiri. Mundawu upezeke opanga galimoto ntchito lifiyamu chitsulo mankwala batire monga mphamvu limatiphunzitsa poyambitsa mafuta ndi dizilo injini.

Pamodzi ndi ubwino onse, LiFePO4 mabatire ndi yaikulu drawback - misa lalikulu ndi miyeso. Izi zimasokoneza ntchito zawo mitundu ina ya makina ndi zipangizo zamagetsi.

Features ntchito

Ngati inu kugula okonzeka zopangidwa mabatire lifiyamu-mankwala, mavuto ndi kukonza ndi ntchito mulibe. Tikuthokoza kwambiri chakuti opanga zinthu amenewa anaikapo mu BMS gulu kuti kuteteza overcharging ndi kuteteza kumaliseche mchitidwe msinkhu wa kuthungo.

Koma ngati inu kugula maselo munthu (mabatire penlight Mwachitsanzo), ndiye inu kusunga diso pa mphamvu batire yekha. Pamene woyang'anira akutsikira pansi pa yovutayi (2.00 V pansipa) mofulumira adzagwa ndi capacitance, kupanga n'zosatheka recharge maselo. Ngati inu M'malo mwake, ingalemetsedwe (pamwamba 3,75 V), selo chabe bulges chifukwa mpweya wa anamasulidwa.

Ngati mumamwa batire zimenezo ndi galimoto magetsi, pambuyo 100% nawuza muyenera kusagwirizana naupereka batire. Apo ayi, batire amawonjezereka chifukwa supersaturation ya magetsi.

malamulo opaleshoni

Ngati mukufuna kugwiritsa ntchito mabatire lifiyamu-mankwala mu mode ozungulira ndi gawo lotetezedwa, mwachitsanzo, monga gwero la mphamvu akuluakulu kapena molumikizana ndi batire dzuwa, muyenera kusamalira kutsitsa mlingo mlandu kwa 3.40-3.45 V. kupirira ntchito zimenezi zimathandiza 'wanzeru' chargers kuti basi woyamba kwathunthu zoperewerazo kotunga mphamvu, ndiyeno kuchepetsa mlingo nkhawa.

Pa ntchito, muyenera kuwunika bwino maselo kapena kugwiritsa ntchito ndalama zapadera kugwirizanitsa (mu batire, iwo anamanga galimoto magetsi). selo vutoli wotchedwa boma zimenezi, pamene voteji okwana chipangizo ndi pa mlingo mwadzina, koma selo voteji amakhala osiyana.

zodabwitsazi ndi chifukwa kusiyana kwa resistances zigawo munthu, osauka kukhudzana therebetween. Ngati maselo ndi voltages osiyana, ndipo m'goli awo mlandu-kumaliseche, amene kwambiri kuchepetsa moyo utumiki wa batire la.

Kuika batire ntchito

Musanagwiritse ntchito mabatire lifiyamu mankwala anasonkhana ku maselo osiyana, chisamaliro ayenera kumwedwa dongosolo akusamala, monga magawo angakhale ndi mlandu mlingo wosiyana. Chifukwa chaichi zigawo zonse cholukanalukana mu kufanana ndi olumikiza rectifier, ndi naupereka. United Choncho ndikofunikira mlandu selo 3.6 V.

Ntchito batire lifiyamu chitsulo mankwala kwa njinga magetsi, inu mwina anaona kuti mu mphindi loyamba batire amapereka mphamvu pazipita, kenako mlandu mofulumira kugwa kwa mlingo wa 3.3-3.0 V. Usaope izi, chifukwa izo ndi ntchito za masiku onse batire la . chakuti kwambiri za kukula kwake (90%) mabodza osiyanasiyana izi.

Pomaliza

Mwachangu lifiyamu-mankwala mabatire ndi 20-30% kuposa wa mabatire ena. Pa nthawi yomweyo iwo atumikire kwa zaka 2-3 yaitali kuposa zina mphamvu, komanso kupereka panopa khola pa nthawi yonse imene ntchito. Onse limeneli likusonyeza zinthu kwake kuwala yabwino.

Komabe, anthu ambiri amanyalanyaza ndi lifiyamu chitsulo mankwala batire. Ubwino ndi kuipa kwa batire wotumbululuka pamaso mtengo - ndi nthawi 5-6 kuposa alipidwa kwa ife maselo-asidi kutsogolera. batire Izi galimoto ndalama avareji pafupifupi 26 chikwi. Rubles.
