Hari ibyiza n'ibibi bifitanye isano n'ubuhanga bubiri bw'ingenzi bwa bateri bukoreshwa mu mishinga yo kubikamo imirasire y'izuba n'iy'amazi. Bateri za aside ya lead zimaze igihe kirekire kandi zoroshye kumva ariko zifite aho zigarukira ku bushobozi bwazo bwo kubika.Bateri ya Lithium-ions zifite ubuzima burebure kandi zifite ibiro byoroshye ariko zihenze cyane.

Ahantu ho kubika ibintu hakunze kuba hari ubwoko bumwe bwa bateri, nk'uko bimeze kuri LG Chem. Ifoto yatanzwe na GreenBrilliance

Ese umuntu ashobora guhuza ibyiza bya buri shimi kugira ngo akore bateri imwe ihendutse kandi ifite ubushobozi bwo hejuru?

Ese umuntu agomba gusenya bateri ye ya aside ya lead kugira ngo amenye imikorere ya bateri nshya ya lithium-ion? Ese umuntu ashobora kongeramo bateri ya aside ya lead ihendutse kuri sisitemu ye ya lithium kugira ngo ihuze n'ubushobozi runaka bwa kilowatt-saa?

Ibibazo byose by'ingenzi bifite igisubizo kitarasobanuka neza: biterwa. Biroroshye kandi nta ngaruka mbi bifite gukomeza gukoresha shimi imwe, ariko hari ibyo wakora.

Gordon Gunn, injeniyeri w’amashanyarazi muri Freedom Solar Power muri Texas, yavuze ko bishoboka guhuza bateri za lead-acid na lithium, ariko binyuze mu guhuza AC gusa.

Yagize ati: “Ntabwo ushobora guhuza bateri za aside ya lead na lithium kuri bisi imwe ya DC. “Mu buryo bwiza, byangiza bateri, kandi mu buryo bubi… umuriro? Guturika? Isesengura ry’igihe n’igihe bikomeza? Simbizi.”

K. Fred Wehmeyer, Visi Perezida Mukuru w’Ubwubatsi muri sosiyete ya bateri ya US Battery Manufacturing Co., yatanze ibisobanuro birambuye.

Wehmeyer yagize ati: “Birashobora gukorwa, ariko ntibyaba byoroshye nko kongeramo bateri za aside ya lead kuri sisitemu ya bateri ya lithium. Sisitemu zombi zaba zikora ku giti cyazo. Sisitemu ya bateri ya lithium izaba ikomeje gusabwa kugenzurwa na BMS yayo ifite charger na charger controller. Sisitemu ya bateri ya aside ya lead yakenera charger yayo cyangwa charge controller ariko ntabwo yakenera BMS. Sisitemu zombi zishobora gutanga imizigo ingana mu buryo bumwe ariko hashobora kuba hakenewe uburyo bwo kugenzura kugira ngo hamenyekane neza ikwirakwizwa ry’imizigo hagati y’ibinyabutabire byombi.”

Troy Daniels, umuyobozi ushinzwe serivisi za tekiniki mu ruganda rwa bateri rwa LFP SimpliPhi Power, ntasaba kuvanga shimi imwe ya bateri, tutibagiwe no kuvanga shimi itandukanye muri sisitemu imwe, ariko yemera ko bishobora gukorwa.

Yagize ati: “Uburyo bubiri bwo guhuza bwaba ari ukugira sisitemu ebyiri zitandukanye (zombi zikoresha charger na inverter) zishobora gusangira umutwaro umwe cyangwa se zigabanye imitwaro ikenewe y’amashanyarazi.” “Hashobora kandi gukoreshwa icyuma cyo kohereza umuriro; icyakora, ibi byasobanura ko bateri imwe cyangwa shimi imwe gusa ari yo ishobora gusharija cyangwa gusohora umuriro icyarimwe kandi ishobora kuba iyo kohereza umuriro hakoreshejwe intoki.”

Gutandukanya imizigo no gushyiraho sisitemu ebyiri akenshi ni akazi katoroshye kurusha uko benshi bifuza.

“Ntabwo twigeze dukorana na sisitemu ya litiyumu/aside ikomoka kuri leta muri Freedom Solar kuko atari inyongera ihendutse, kandi tugerageza koroshya uburyo dushyiramo bateri dukoresheje uburyo bumwe gusa bwa bateri n’ikintu kimwe cya bateri,” ibi ni ibyatangajwe na Josh Meade, ushinzwe ikoranabuhanga n’imiterere y’ibikoresho.

Hari ikigo kimwe kigerageza koroshya guhuza ibi bintu bibiri. Uruganda rukora ibikoresho by'amashanyarazi bitwara imizigo, Goal Zero, rufite sitasiyo y'amashanyarazi ya Yeti ikoresha litiyumu ishobora gukoreshwa mu gushakisha igice cy'ibikoresho byo mu rugo. Yeti 3000 ni bateri ya lithiyumu ya NMC ya 3-kWh, 70-lb ishobora gushyigikira imiyoboro ine. Niba hakenewe ingufu nyinshi, Goal Zero itanga module yayo ya Yeti Link Expansion Module yemerera kongeramo bateri zo kwagura zikoresha lead-acid. Yego, nibyo: Bateri ya lithiyumu Yeti ishobora guhuzwa na lead-acid.

“Ikigega cyacu cyo kwagura ni uruhererekane rw’amayobera, batiri ya aside ya lead. Ibi bigufasha gukoresha ibikoresho by’ikoranabuhanga biri muri Yeti [sisitemu ishingiye kuri lithium] ariko bikongera batiri,” ibi byavuzwe na Bill Harmon, GM kuri Goal Zero. “Ku gipimo cya 1.25-kWh, ushobora kongeramo batiri nyinshi [za aside ya lead] uko ushaka. Umukiriya ashobora kuzishyiramo gusa. Uhita ubona uburyo bwo gutwara batiri ya lithium hamwe na batiri za aside ya lead zihendutse ziri mu rugo.”

Ibibazo bikomeye iyo ugerageza guhuza lithium na aside lead hamwe ni voltage zitandukanye, imiterere ya charger hamwe n'imipaka ya charge/decharger. Iyo bateri zidafite voltage imwe cyangwa zisohora charger ku gipimo kidahuye, ingufu zihita zikorana vuba. Iyo ingufu zikora vuba, ibibazo byo gushyushya bivuka kandi bigatuma imikorere ya bateri irushaho kuba myiza.

Goal Zero ikemura iki kibazo ikoresheje igikoresho cyayo cya Yeti Link. Yeti Link ni uburyo bugezweho bwo gucunga bateri bukwiriye bateri ya lithium ya Yeti y’umwimerere icunga voltages no charger mu bindi bintu bitandukanye.

“Yeti Link irimo kugenzura uburyo umuriro ukoreshwa hagati ya bateri.” Harmon yagize ati: “Turinda mu buryo bwizewe, ku buryo bateri ya lithium itamenya ko ifitanye isano na bateri ya aside ya lead.”

Harmon yavuze ko Yeti 3000 ishobora kuba ntoya ugereranyije na bateri zisanzwe za lithium zo mu rugo - LG Chem. Tesla na sonnets models akenshi zigira nibura 9.8 kWh z'ingufu - ariko ibyo ni byo bikurura, kandi niba umuntu ashobora kuyigura kugeza kuri 9-kWh hamwe na bateri zihendutse kandi akanajyana bateri ya lithium mu gihe cyo gukambika cyangwa gusimbuka inyuma, kuki atabikora?

Harmon yagize ati: “Uburyo bwacu ni ubw’abantu bose bo mu gihugu badafite $15,000 yo gushora mu bubiko bw’ingufu. Hanyuma nindangiza, icyo ngomba gukora ni ikintu gihoraho mu rugo rwanjye.” “Yeti ni ubw’abantu bashobora gutakaza amafaranga. Ubu buryo bwacu bugizwe n’amadolari 3,500 yose.”

Goal Zero ubu iri ku gisekuru cya gatanu cy’umusaruro wayo, bityo ikaba yizeye ubushobozi bwayo bwo guhuza litiyumu n’umusemburo. Ariko ku bandi benshi batagorwa no kuvanga ikoranabuhanga rya batiri, sisitemu ebyiri zihariye kandi zigenga zishobora gushyirwa mu bucuruzi bumwe cyangwa mu rugo rumwe - igihe cyose byashyizweho n’inzobere mu by’amashanyarazi.

“Uburyo bworoshye kandi bwizewe bwo kongera ubushobozi bwo kubika ibintu buhendutse kuri sisitemu ya lithium isanzweho ni ukugabanya imizigo no kuyishyira ukwayo muri sisitemu ebyiri za bateri.” Wehmeyer wo muri US Battery yagize ati: “Uko byagenda kose. Bigomba gukorwa n’inzobere yabyigiye kugira ngo umutekano ukomeze kubungabungwa.”
