Pali zabwino ndi zoyipa zomwe zimagwirizanitsidwa ndi kapangidwe ka mabatire awiri akuluakulu omwe amagwiritsidwa ntchito mu ntchito zosungiramo zinthu pogwiritsa ntchito mphamvu ya dzuwa ndi mphamvu ya dzuwa. Mabatire a lead-acid akhalapo kwa nthawi yayitali ndipo amamveka mosavuta koma ali ndi malire pa mphamvu yawo yosungira.Batri ya Lithium-ionZimakhala ndi moyo wautali ndipo zimakhala zopepuka koma zimakhala zodula kwambiri.

Malo osungira nthawi zambiri amakhala ndi batire imodzi, monga momwe zilili ndi LG Chem, apa. Chithunzi mwachilolezo cha GreenBrilliance

Kodi munthu angaphatikize ubwino wa mankhwala aliwonse kuti apange batire imodzi yotsika mtengo komanso yolimba kwambiri?

Kodi munthu ayenera kuswa batire yake ya lead-acid kuti agwiritse ntchito bwino batire yatsopano ya lithiamu-ion? Kodi munthu angawonjezere mabatire otsika mtengo a lead-acid ku dongosolo lake la lithiamu kuti akwaniritse mphamvu inayake ya kilowatt-hour?

Mafunso onse ofunikira okhala ndi yankho losamveka bwino: zimadalira. N'kosavuta komanso kopanda chiopsezo kugwiritsa ntchito njira imodzi, koma pali njira zina zothanirana nazo.

Gordon Gunn, mainjiniya wamagetsi ku Freedom Solar Power ku Texas, anati mwina n'zotheka kulumikiza mabatire a lead-acid ndi lithiamu pamodzi, koma kudzera mu AC coupling yokha.

“Simungathe kulumikiza mabatire a lead-acid ndi lithiamu pa basi imodzi ya DC,” iye anatero. “Komabe, zingawononge mabatire, ndipo zikawononga kwambiri…moto? Kuphulika? Kuwerenga kwa nthawi yopitilira? Sindikudziwa.”

K. Fred Wehmeyer, wachiwiri kwa nduna ya uinjiniya ku kampani ya mabatire a lead-acid ku US Battery Manufacturing Co., adapereka kufotokozera kwina.

"Itha kupangidwa, koma sizingakhale zosavuta monga kungowonjezera mabatire a lead-acid ku dongosolo la batri la lithiamu. Machitidwe awiriwa angachite zinthu pawokha," adatero Wehmeyer. "Dongosolo la batri la lithiamu liyenerabe kuyendetsedwa ndi BMS yake yokhala ndi chowongolera chake cha charger ndi charger. Dongosolo la batri la lead-acid lingafunike chowongolera chake cha charger ndi/kapena charger koma silingafunike BMS. Machitidwe awiriwa akhoza kupereka katundu wofanana nthawi imodzi koma pangafunike kukhala ndi ulamuliro wina kuti agawire bwino kugawa kwa katundu pakati pa mankhwala awiriwa."

Troy Daniels, manejala wautumiki waukadaulo wa kampani yopanga mabatire a LFP SimpliPhi Power, sakulimbikitsa kusakaniza mankhwala ofanana a batire osatinso mankhwala osiyanasiyana mu dongosolo limodzi, koma akuvomereza kuti zingatheke.

"Njira zingapo zophatikizira zingakhale njira yokhala ndi machitidwe awiri osiyana (onse awiri ochaja ndi inverter) omwe angagawire katundu wofanana kapena kugawa katundu wamagetsi wofunikira." Iye anati. "Chosinthira magetsi chingagwiritsidwenso ntchito; komabe, izi zikutanthauza kuti mabatire amodzi okha kapena mankhwala amatha kutchaja kapena kutulutsa mphamvu nthawi imodzi ndipo mwina ayenera kukhala kusamutsa kwamanja."

Kulekanitsa katundu ndi kukhazikitsa machitidwe awiri nthawi zambiri kumakhala kovuta kwambiri kuposa momwe ambiri amafunira.

"Sitinagwirizane ndi makina osakanikirana a lithiamu/lead-acid ku Freedom Solar chifukwa sangakhale chowonjezera chotsika mtengo, ndipo timayesetsa kuti mabatire athu azikhala osavuta pogwiritsa ntchito batire imodzi yokha komanso batire imodzi yokha," adatero Josh Meade, woyang'anira kapangidwe ka nyumba komanso wopanga mapulani.

Pali kampani imodzi yomwe ikuyesera kupanga kuphatikiza zinthu ziwirizi kukhala kosavuta pang'ono. Kampani yopanga zinthu zamagetsi zonyamulika, Goal Zero, ili ndi malo opangira magetsi otchedwa Yeti Portable Power Station omwe angagwiritsidwe ntchito posungira zinthu zina kunyumba. Yeti 3000 ndi batire ya lithiamu ya 3-kWh, 70-lb NMC lithium yomwe imatha kuthandizira ma circuits anayi. Ngati pakufunika mphamvu zambiri, Goal Zero imapereka Yeti Link Expansion Module yake yomwe imalola kuwonjezera mabatire okulitsa a lead-acid. Inde, ndizowona: Batire ya lithiamu Yeti ikhoza kugwirizanitsidwa ndi lead-acid.

"Thanki yathu yowonjezera ndi yozungulira modabwitsa, batire ya lead-acid. Izi zimakulolani kugwiritsa ntchito zamagetsi mu Yeti [dongosolo lochokera ku lithiamu] koma zimakulitsa batire," adatero Bill Harmon, GM ku Goal Zero. "Pa 1.25-kWh iliyonse, mutha kuwonjezera [mabatire a lead-acid] ambiri momwe mukufunira. Kasitomala amatha kungowalumikiza. Mwadzidzidzi mumapeza kuti batire ya lithiamu ndi mabatire otsika mtengo a lead-acid omwe ali kunyumba."

Mavuto akuluakulu poyesa kulumikiza lithiamu ndi lead-acid ndi ma voltage osiyanasiyana, ma charger profiles ndi malire a charge/discharge. Ngati mabatire ali ndi voltage yofanana kapena akutulutsa mphamvu mosagwirizana, mphamvuyo imayenda mwachangu pakati pawo. Mphamvuyo ikayenda mwachangu, mavuto otenthetsera amayamba ndipo amachepetsa mphamvu ya batri.

Goal Zero imathetsa vutoli ndi chipangizo chake cha Yeti Link. Yeti Link kwenikweni ndi njira yoyendetsera bwino batire yoyenera batire yoyambirira ya Yeti lithiamu yomwe imayang'anira ma voltage ndi chaji pakati pa mitundu yosiyanasiyana ya mankhwala.

“Yeti Link ikulamulira kusamutsa mphamvu pakati pa mabatire.” Harmon anatero. “Timateteza mwanjira yotetezeka, kotero kuti batire ya lithiamu sidziwa ngakhale kuti yalumikizidwa ndi batire ya lead-acid.”

Yeti 3000 ikhoza kukhala yaying'ono kuposa mabatire achikhalidwe a lithiamu kunyumba - LG Chem. Mitundu ya Tesla ndi sonnets nthawi zambiri imakhala ndi mphamvu zosachepera 9.8 kWh - koma ndicho chikoka chake, Harmon adatero. Ndipo ngati wina angathe kukulitsa mpaka kufika pa 9-kWh ndi mabatire otsika mtengo komanso kutenga batire ya lithiamu akamapita kukagona kapena kukwera m'mbuyo, bwanji osatero?

"Dongosolo lathu ndi la anthu onse mdziko muno omwe alibe $15,000 yoti agwiritse ntchito poyika magetsi. Kenako ndikamaliza, ndiyenera kukhala chinthu chokhazikika m'nyumba mwanga," adatero Harmon. "Yeti ndi ya iwo omwe ali pachiwopsezo cha zomwe akuwononga ndalama. Dongosolo lathu ndi $3,500 yonse."

Goal Zero tsopano ili pa m'badwo wake wachisanu wa malonda, kotero ili ndi chidaliro mu kuthekera kwake kophatikiza lithiamu-lead. Koma kwa ena ambiri omwe samasuka kusakaniza mankhwala a batri, makina awiri odziyimira pawokha komanso odziyimira pawokha amatha kukhazikitsidwa mu bizinesi imodzi kapena m'nyumba imodzi - bola ngati akhazikitsidwa ndi katswiri wamagetsi.

"Njira yosavuta komanso yotetezeka yowonjezera mphamvu yosungira yotsika mtengo ku dongosolo la lithiamu lomwe lilipo ndi kugawa katunduyo ndikugawa padera ku machitidwe awiri a mabatire." Wehmeyer wa US Battery adatero. "Mulimonsemo. Izi ziyenera kuchitidwa ndi katswiri wophunzitsidwa kuti asunge chitetezo."
