Incamake: RoyPow truck nshya yakozwe na All-Electric APU (Auxiliary Power Unit) ikoresha bateri za lithium-ion kugira ngo ikemure ibibazo bya APU z'truck ziri ku isoko.
Ingufu z'amashanyarazi zahinduye isi. Ariko, ibura ry'ingufu n'ibiza bikabije biriyongera mu buryo bukabije. Hamwe n'izamuka ry'ingufu nshya, icyifuzo cy'ibisubizo by'ingufu binoze, bitekanye kandi birambye kiriyongera cyane. Ni nako bimeze ku ikenerwa rya camion All-Electric APU (Auxiliary Power Unit).
Ku batwara amakamyo benshi, amakamyo yabo afite amapine 18 aba iwabo kure y'iwabo mu gihe cy'ingendo ndende. Kuki abatwara amakamyo mu muhanda batagomba kwishimira umwuka mwiza wo gukonjesha mu mpeshyi n'ubushyuhe mu gihe cy'itumba nk'uko bigenda mu rugo? Kugira ngo babone iyi nyungu, ikamyo igomba kuba ikora iyo idafite lisansi iyo ifite ibisubizo bisanzwe. Mu gihe amakamyo ashobora gukoresha litiro 0.85 kugeza kuri 1 za lisansi ku isaha yo gukora iyo idafite lisansi. Mu gihe cy'umwaka, ikamyo itwara abagenzi benshi ishobora gukora amasaha agera ku 1800, ikoresha litiro zigera kuri 1500 za mazutu, bingana n'imyanda ya lisansi ya $8700. Gutwara imyanda mu gihe cyo gukora iyo idafite lisansi ntibitwara amafaranga gusa, ahubwo bigira ingaruka zikomeye ku bidukikije. Ingano nini ya dioxyde de carbone isohorwa mu kirere irushaho kwiyongera uko igihe kigenda kandi ikagira uruhare runini mu mihindagurikire y'ikirere n'ibibazo by'ihumana ry'ikirere hirya no hino ku isi.
Niyo mpamvu Ikigo cy’Ubushakashatsi ku Bikorwa by’Ubwikorezi cy’Abanyamerika kigomba gushyiraho amategeko n’amabwiriza arwanya ihindagurika ry’imodoka, aho amashanyarazi y’inyongera ya mazutu (APU) aba ingirakamaro. Iyo moteri ya mazutu yongewe ku ikamyo itanga ingufu zikoreshwa mu gushyushya no mu gikoni, zimya moteri y’ikamyo kandi wishimire ko ikamyo nziza ihinduka impamo. Iyo ukoresheje ikamyo ya mazutu, hafi 80% by’ikoreshwa ry’ingufu rishobora kugabanuka, ihumana ry’ikirere rikagabanuka cyane icyarimwe. Ariko APU yo gutwika irakoreshwa cyane - isaba guhindurwa amavuta buri gihe, kuyungurura lisansi, no kubungabunga muri rusange (imiyoboro, imigozi, na valve). Kandi umushoferi w’ikamyo ntashobora gusinzira neza kuko ijwi ryayo rirenga irya kamyo nyayo.
Bitewe n’ubwiyongere bw’ibyifuzo by’ibikoresho bikonjesha mu ijoro n’abatwara imizigo mu turere ndetse n’uburyo bidakoreshwa cyane, APU y’amakamyo akoresha amashanyarazi iraza ku isoko. Ikoresha andi mapaki y’amabateri ashyirwa muri iyo kamyo kandi agasharishwa na alternator iyo ikamyo irimo kugenda. Mbere na mbere bateri za aside ya lead, urugero bateri za AGM zitoranywa kugira ngo zikoreshe sisitemu. Bateri zikoresha bateriikamyo APUbitanga ihumure ryinshi ry’abashoferi, kuzigama lisansi cyane, gushaka/gufata abashoferi neza, kugabanya ikiguzi cyo kubungabunga. Mu gihe tuvuze imikorere ya APU y’ikamyo, ubushobozi bwo gukonjesha buri imbere no hagati. APU ya mazutu itanga hafi 30% by’ingufu zo gukonjesha kurusha sisitemu ya APU ya batiri ya AGM. Byongeye kandi, igihe cyo gukora ni cyo kibazo gikomeye abashoferi n’amato bafite ku byerekeye APU z’amashanyarazi. Muri rusange, igihe cyo gukora cya APU y’amashanyarazi ni amasaha 6 kugeza kuri 8. Ibyo bivuze ko traktori ishobora gukenera gutangizwa amasaha make kugira ngo batiri zishyuhe.
Mu minsi ishize, RoyPow yashyize ahagaragara imodoka ya bateri ya lithium-ion imwe ifite ingufu zose (Auxiliary Power Unit). Ugereranyije na bateri zisanzwe za aside lead, iyi bateri ya LiFePO4 irusha izindi imbaraga mu bijyanye n'ikiguzi, ubuzima bwa serivisi, imikorere myiza y'ingufu, kubungabunga no kurengera ibidukikije. Imodoka nshya ya bateri ya lithium All-Electric APU (Auxiliary Power Unit) yagenewe gukemura ibibazo biri mu bisubizo bya APU bya mazutu n'amakamyo y'amashanyarazi. Muri ubu buryo harimo alternator y'ubwenge ya 48V DC, iyo ikamyo ikora mu muhanda, alternator izamura ingufu za moteri y'ikamyo ku mashanyarazi ikabikwa muri bateri ya lithium. Kandi bateri ya lithium ishobora kwishyuzwa vuba mu gihe cy'isaha imwe cyangwa ebyiri kandi igaha HVAC ingufu zihoraho kugeza ku masaha 12 kugira ngo ihaze ikibazo cyo gutwara amakamyo mu modoka ndende. Muri ubu buryo, 90% by'ikiguzi cy'ingufu gishobora kugabanuka kuruta gukoresha inzoga kandi yakoreshaga ingufu z'icyatsi kibisi n'izisukuye aho gukoresha mazutu. Ibyo bivuze ko hazabaho imyuka ihumanya ikirere ku nshuro ya 0 n'urusaku rudahagije. Bateri za lithiyumu zirangwa no gukoresha ingufu nyinshi mu buryo buhagije, kumara igihe kirekire kandi nta n'isukura, ibi bifasha abatwara amakamyo kwirinda impungenge z'ibura ry'ingufu n'ibibazo byo kubungabunga. Ikindi kandi, ubushobozi bwo gukonjesha bwa 48V DC air conditioner y'ikamyo All-Electric APU (Auxiliary Power Unit) ni 12000BTU/h, hafi ya APU za mazutu.
Ikamyo nshya ya batiri ya lithium isukuye, APU y'amashanyarazi yose (Auxiliary Power Unit) izaba ari yo nzira nshya yo gusimbura APU ikoreshwa ku isoko, bitewe n'ingufu zayo nke, igihe kirekire cyo gukora no kutagira imyuka ihumanya ikirere.
Nk'umuti ukoreshwa mu “kuzimya moteri no kurwanya imyuka idakora”, sisitemu ya RoyPow y'amashanyarazi yose irinda ibidukikije kandi irambye kuko ikuraho imyuka ihumanya ikirere, ikurikiza amabwiriza yo kurwanya imyuka ihumanya ikirere mu gihugu hose, arimo ibisabwa n'Ikigo gishinzwe imicungire y'ikirere cya California (CARB), byashyizweho kugira ngo birinde ubuzima bw'abantu no guhangana n'ihumana ry'ikirere muri leta. Byongeye kandi, iterambere mu ikoranabuhanga rya bateri ririmo kongera igihe cy'imikorere y'iyi sisitemu y'ikirere, bigafasha kugabanya impungenge z'abaguzi ku bijyanye n'ihungabana ry'amashanyarazi. Icya nyuma ariko kitari gito, gifite akamaro kanini ko kunoza ubuziranenge bw'ibitotsi by'abatwara amakamyo kugira ngo bigabanye umunaniro w'abashoferi mu nganda zitwara amakamyo.
