Pali zabwino ndi zoyipa zomwe zimalumikizidwa ndi ma chemistry awiri akulu a batri omwe amagwiritsidwa ntchito pama projekiti a solar + yosungirako.Mabatire a asidi okhala ndi lead akhalapo kwa nthawi yayitali ndipo amamveka mosavuta koma ali ndi malire pakusunga kwawo.Batire ya lithiamu-ions amakhala ndi moyo wautali komanso wopepuka koma wokwera mtengo.

Kuyika kosungirako kumakhala ndi mtundu wa batri limodzi, monga LG Chem, apa.Chithunzi mwachilolezo cha GreenBrilliance

Kodi munthu angaphatikize zabwino za chemistry iliyonse kuti apange banki imodzi yotsika mtengo, yokhala ndi batire yapamwamba kwambiri?

Kodi wina amayenera kugwetsa banki ya batri ya acid-acid kuti agwiritse ntchito batri yatsopano ya lithiamu-ion?Kodi wina angawonjezere mabatire a lead-acid otsika mtengo pang'ono ku makina awo a lithiamu kuti akwaniritse mphamvu inayake ya ola la kilowatt?

Mafunso onse ofunikira omwe ali ndi yankho lodziwika bwino: zimatengera.Ndikosavuta komanso kowopsa kukhala ndi chemistry imodzi, koma pali ntchito zina.

Gordon Gunn, injiniya wamagetsi ku Freedom Solar Power ku Texas, adanena kuti n'zotheka kugwirizanitsa mabatire a lead-acid ndi lithiamu pamodzi, koma kupyolera mu kugwirizana kwa AC.

"Simungathe kulumikiza mabatire a lead-acid ndi lithiamu pa basi yomweyo ya DC," adatero."Chabwino, zitha kuwononga mabatire, ndipo poyipa kwambiri ... moto?Kuphulika?Kuwerenga kwanthawi yopitilira mumlengalenga?Sindikudziwa."

K. Fred Wehmeyer, VP wamkulu wa engineering pa kampani ya lead-acid battery US Battery Manufacturing Co., anapereka kufotokozera kwina.

"Itha kupangidwa, koma sizingakhale zophweka monga kungowonjezera mabatire a lead-acid ku batire ya lithiamu.Machitidwe awiriwa akadakhala akudziyimira pawokha, "adatero Wehmeyer."Batire ya lithiamu ikadafunikabe kuyendetsedwa ndi BMS yake yokhala ndi charger yake komanso chowongolera.Batire ya lead-acid ingafunike charger yake ndi/kapena chowongolera koma sichingafune BMS.Makina awiriwa atha kukhala akupereka katundu wofananira koma pangafunike kuwongolera kuti pakhale kugawa bwino pakati pamakampani awiriwa. ”

Troy Daniels, woyang'anira ntchito zaukadaulo wa LFP wopanga batire SimpliPhi Power, samalimbikitsa kusakaniza chemistry ya batri yomwe imangosiya kusiyanitsa chemistry mu dongosolo limodzi, koma amavomereza kuti zitha kuchitika.

"Njira zingapo zophatikizira zitha kukhala njira yokhala ndi zida ziwiri zodzipatula (zosefera ndi ma inverter) zomwe zimatha kugawana katundu wamba kapena kugawa magetsi ofunikira.” adatero.“Siwichi yosinthira itha kugwiritsidwanso ntchito;komabe, izi zingatanthauze kuti batire imodzi yokha kapena chemistry ingathe kulipiritsa kapena kutulutsa panthawi imodzi ndipo kuyenera kukhala kusamutsa pamanja.

Kulekanitsa katundu ndi kukhazikitsa machitidwe awiri nthawi zambiri ndi ntchito yovuta kwambiri kuposa momwe ambiri amafunira.

"Sitinachitepo ndi hybrid lithiamu / lead-acid system ku Freedom Solar chifukwa sichingakhale chowonjezera chotsika mtengo, ndipo timayesetsa kuti makhazikitsidwe athu a batri akhale osavuta pogwiritsa ntchito chemistry imodzi yokha ndi batri imodzi, "Anatero Josh Meade, PE komanso woyang'anira mapangidwe.

Pali kampani imodzi yomwe ikuyesera kuti kuphatikiza chemistry ziwirizi kukhala kosavuta.Opanga magetsi onyamula Goal Zero ali ndi lithiamu yochokera ku Yeti Portable Power Station yomwe ingagwiritsidwe ntchito posungirako pang'ono kunyumba.Yeti 3000 ndi 3-kWh, 70-lb NMC lithiamu batire yomwe imatha kuthandizira mabwalo anayi.Ngati pakufunika mphamvu zambiri, Goal Zero ikupereka Yeti Link Expansion Module yomwe imalola kuti mabatire owonjezera a acid-acid awonjezere.Inde, ndiko kulondola: Batire ya lithiamu Yeti ikhoza kuphatikizidwa ndi asidi wotsogolera.

"Thanki yathu yokulirapo ndi njira yodabwitsa, batire ya acid-acid.Izi zimakupatsani mwayi wogwiritsa ntchito zamagetsi mu Yeti [lithium-based system] koma mumakulitsa batire, "atero a Bill Harmon, GM ku Goal Zero."Pa 1.25-kWh iliyonse, mutha kuwonjezera [mabatire a asidi a lead] momwe mungafunire.Makasitomala amatha kungowalumikiza. Mwadzidzidzi mumapeza kusuntha kwa batri ya lithiamu ndi mabatire otsika mtengo a asidi okhala kunyumba.

Zovuta zazikulu poyesa kulumikiza lithiamu ndi asidi wotsogolera palimodzi ndi ma voltages awo osiyanasiyana, ma profiles olipira ndi malire amalipiro / kutulutsa.Ngati mabatire atuluka mumagetsi omwewo kapena akutuluka pamitengo yosagwirizana, mphamvuyo imathamanga mwachangu pakati pawo.Mphamvu ikathamanga mwachangu, zovuta zimayamba ndikuwonjezera mphamvu ya batire.

Goal Zero imayang'anira izi ndi chipangizo chake cha Yeti Link.Yeti Link kwenikweni ndi njira yotsogola yoyendetsera batire yoyenera batire yoyambirira ya Yeti lithiamu yomwe imayendetsa ma voltages ndi kulipiritsa pakati pa chemistry zosiyanasiyana.

"Yeti Link ikuwongolera kutumiza kwamagetsi pakati pa mabatire.” adatero Harmon."Timateteza m'njira yotetezeka, kotero kuti batri ya lithiamu sadziwa nkomwe kuti yakwatiwa ndi batri ya acid-acid."

Yeti 3000 ikhoza kukhala yaying'ono kuposa mabatire anyumba a lithiamu - LG Chem.Mitundu ya Tesla ndi ma sonnet nthawi zambiri imakhala ndi mphamvu ya 9.8 kWh - koma ndichojambula chake, adatero Harmon.Ndipo ngati wina angayikulitse mpaka chizindikiro cha 9-kWh ndi mabatire otsogola otsika mtengo komanso kutenga batri ya lithiamu pomanga msasa kapena kutsamira, bwanji osatero?

“Dongosolo lathu ndi la anthu onse mdziko muno omwe alibe $15,000 kuti agwiritse ntchito posungira mphamvu.Ndiyeno ndikamaliza, zonse ndiyenera kukhala chinachake chokhazikika mnyumba mwanga,” adatero Harmon."Yeti ndi ya iwo omwe ali pachiwopsezo cha zomwe amawononga ndalama.Dongosolo lathu ndi $3,500 yonse yoyikidwa. ”

Goal Zero tsopano pa m'badwo wachisanu wa mankhwala, choncho ndi chidaliro mu mphamvu zake lifiyamu-kutsogolera osakaniza.Koma kwa ena ambiri omwe sakhala omasuka kusakaniza chemistry ya batri, makina awiri odziyimira pawokha amatha kukhazikitsidwa mubizinesi imodzi kapena m'nyumba - bola atakhazikitsidwa ndi katswiri wamagetsi.

"Njira yosavuta komanso yotetezeka yowonjezerera kusungirako zotsika mtengo ku kachitidwe ka lithiamu kamene kalipo ingakhale kugawa katundu ndi kuwagawa padera ku machitidwe awiri a batri.” US Battery a Wehmeyer adatero."Mwanjira zonse.Izi ziyenera kuchitidwa ndi akatswiri ophunzitsidwa bwino kuti akhale otetezeka.
