Intangiriro: Catherine von Berg, Umuyobozi Mukuru wa California Battery Company, yaganiriye ku mpamvu atekereza ko fosifate y'icyuma ya lithium izaba ari yo ikoreshwa cyane mu gihe kizaza.
Umusesenguzi w’umunyamerika Wood Mackenzie yavuze ko mu cyumweru gishize, fosfeti y’icyuma ya lithiamu (LFP) izasimbura oxide ya lithiamu manganese cobalt (NMC) nk’ikintu gikomeye gikomeza kubika ingufu. Nubwo iki ari igitekerezo gikomeye, Simpliphi irashaka guteza imbere iyi mpinduka vuba.
Umuyobozi Mukuru wa Simpliphi, Catherine Von Burg, yagize ati: “Hari ikintu gikomeye cyane kirimo kugira ingaruka ku nganda, gishobora kugorana kugipima cyangwa kucyumva. Ibi bifitanye isano n’ibyago bikomeje kubaho: inkongi z’umuriro, guturika, nibindi bikomeje kubaho bitewe n’ibinyabutabire bya lithium ion bikomoka kuri NMC, cobalt.”
Von Burg yizera ko akaga ka kobalti mu bijyanye na batiri katavumbuwe vuba aha. Mu myaka icumi ishize, abantu bafashe ingamba zo kugabanya ikoreshwa n'ibyangirika bya kobalti. Uretse ibyago bifitanye isano na kobalti nk'icyuma, uburyo inganda zibona kobalti akenshi si bwo bwiza.
Nyiri ikigo gitunganya ingufu gifite icyicaro muri California yagize ati: "Ikigaragara ni uko udushya twa mbere muri iyoni ya lithium twashingiye kuri okiside ya kobalti. Ubwo inganda zatangiraga gutera imbere, zinjira mu mwaka wa 2011/12, (abakora batangiye) kongeramo manganese na nikeli n'ibindi byuma kugira ngo bifashe mu kugabanya cyangwa kugabanya ibyago by'ibanze biterwa na kobalti."
Ku bijyanye n'iterambere ry'impinduramatwara mu by'ubutabire vuba kurusha uko byari byitezwe, Simpliphi yatangaje ko nubwo icyorezo cyagize ingaruka, ibicuruzwa byacyo byiyongereyeho 30% uko umwaka utashye mu 2020. Iyi sosiyete ivuga ko ibi biterwa n'abakiriya bashaka umutekano n'ubudahangarwa bw'uburozi ndetse n'amashanyarazi yo kubafasha mu mutekano. Hari kandi abakiriya benshi kuri uru rutonde. Simpliphi yatangaje uyu mwaka umushinga wo kubika ingufu za batiri hamwe n'ibigo by'imari AEP na Pepco.
AEP na Southwest Electric Power Company bashyizeho uburyo bwo kwerekana uburyo bwo kubika ingufu hakoreshejwe ingufu zikomoka ku mirasire y'izuba, butarimo cobalt. Muri ubu buryo, hakoreshwa bateri ya Simpliphi 3.8 kWh, inverter na Heila controller nk'uburyo bwo gucunga bateri n'ingufu. Iyi miterere igenzurwa na Heila Edge hanyuma igashyirwa hamwe mu buryo bw'ikoranabuhanga bukwirakwizwa, bushobora gukoreshwa n'umugenzuzi uwo ari we wese.
Mu guteganya kwihutisha impinduramatwara ya bateri, Von Burg yerekanye ibicuruzwa bishya by’ikigo cye, bateri ya amplifier ya 3.8 kWh, ifite uburyo bwihariye bwo gucunga ibintu bukoresha imiterere y’ibipimo, uburinzi, igenzura, n’itanga raporo. Kugenzura, kwemeza no kuringaniza imikorere.
Umuyobozi Mukuru yagize ati: "Iyo twinjiye ku isoko, buri bateri zacu zifite BMS (Sisitemu yo Gucunga Bateri), kandi uburyo bwo kuyikoresha bushingiye ku muyoboro w'amashanyarazi." Mu yandi magambo, ubu ni uburyo bwo gucunga bateri z'imbere mu buryo bw'ubwenge kugira ngo twongere imikorere. Uko isoko rigenda ritera imbere kandi rigakora imishinga y'ingirakamaro, tugomba kugira uburyo bwinshi bwo guhuza no gushyiramo ubwenge muri BMS, kugira ngo bateri zacu zishobore kurenga umuyoboro w'amashanyarazi wa inverter na set point charge controller hamwe n'amakuru ya digitale n'uburyo bwo kuyihuza Ibikoresho, urugero, micro-smart grid" site controller.
Muri icyo gihe, Umuyobozi Mukuru yagize ati: "BMS y'iyi bateri ya amplifier ni ikintu tumaze hafi umwaka twiga. Bateri ihuzwa mu buryo bwikora. Si ngombwa kutubwira niba bateri ari No. 1 cyangwa No. 100. Hari inverter ishaja aho ikorera. Igenzura, ryateguwe mbere kugira ngo rivuge ururimi rwa inverter kandi rishobora guhuzwa."
