Chotsitsa: RoyPow truck yatsopano yotchedwa All-Electric APU (Auxiliary Power Unit) yoyendetsedwa ndi mabatire a lithiamu-ion kuti ithetse mavuto a ma APU a truck omwe alipo pamsika.
Mphamvu zamagetsi zasintha dziko lapansi. Komabe, kusowa kwa mphamvu ndi masoka achilengedwe zikuchulukirachulukira komanso moopsa. Chifukwa cha kubwera kwa mphamvu zatsopano, kufunikira kwa njira zothetsera mphamvu zogwira mtima, zotetezeka, komanso zokhazikika kukuwonjezeka mofulumira. Ndi momwemonso kufunikira kwa magalimoto onse amagetsi (Auxiliary Power Unit).
Kwa oyendetsa magalimoto ambiri, magalimoto awo okhala ndi mawilo 18 amakhala kutali ndi kwawo panthawi ya maulendo ataliatali. N’chifukwa chiyani oyendetsa magalimoto pamsewu sayenera kusangalala ndi mpweya wabwino nthawi yachilimwe komanso kutentha nthawi yozizira ngati kunyumba? Kuti asangalale ndi izi, galimotoyo iyenera kukhala ikugwira ntchito ngati ili ndi njira zamakono. Ngakhale magalimoto akuluakulu amatha kugwiritsa ntchito magaloni 0.85 mpaka 1 a mafuta pa ola limodzi logwira ntchito. Pakatha chaka, galimoto yayitali imatha kugwira ntchito kwa maola pafupifupi 1800, ikugwiritsa ntchito magaloni pafupifupi 1500 a dizilo, zomwe ndi pafupifupi 8700USD mafuta otayidwa. Sikuti kungotaya mafuta kokha komanso kumawononga ndalama, komanso kumawononga kwambiri chilengedwe. Mpweya woipa kwambiri umatulutsidwa mumlengalenga pakapita nthawi ndipo umathandizira kwambiri kusintha kwa nyengo ndi mavuto oipitsa mpweya padziko lonse lapansi.
Ichi ndichifukwa chake bungwe la American Transportation Research Institute liyenera kukhazikitsa malamulo ndi malangizo oletsa kulephera kugwira ntchito komanso komwe mayunitsi amphamvu othandizira a dizilo (APU) ndi othandiza. Ndi injini ya dizilo yowonjezeredwa pagalimoto imapereka mphamvu makamaka pa chotenthetsera ndi choziziritsira mpweya, zimitsani injini ya galimoto ndikusangalala ndi galimoto yabwino. Ndi APU ya galimoto ya dizilo, pafupifupi 80 peresenti ya mphamvu zomwe zimagwiritsidwa ntchito zimatha kuchepetsedwa, kuipitsidwa kwa mpweya kumachepa kwambiri nthawi imodzi. Koma APU yoyaka ndi yochuluka kwambiri - imafuna kusintha mafuta nthawi zonse, zosefera mafuta, ndi kukonza koteteza (mahose, ma clamp, ndi ma valve). Ndipo woyendetsa galimoto sangagone mokwanira chifukwa imamveka kwambiri kuposa galimoto yeniyeniyo.
Popeza kufunikira kwa mpweya woziziritsa usiku kukuchulukirachulukira kwa oyendetsa magalimoto m'deralo komanso zinthu zosakonza bwino, APU yamagalimoto amagetsi ikupezeka pamsika. Amayendetsedwa ndi mabatire ena omwe amaikidwa mgalimoto ndipo amalipiridwa ndi alternator galimoto ikamayenda. Poyamba mabatire a lead-acid, mwachitsanzo mabatire a AGM, amasankhidwa kuti aziyendetsa makinawo. Batire imayendetsedwa ndi batire.galimoto ya APUamapereka chitonthozo cha madalaivala, kusunga mafuta ambiri, kulemba/kusunga madalaivala bwino, kuchepetsa kusagwira ntchito, kuchepetsa ndalama zokonzera. Ponena za magwiridwe antchito a APU yamagalimoto, mphamvu zoziziritsira zimakhala patsogolo ndi pakati. APU ya dizilo imapereka mphamvu yozizira pafupifupi 30% kuposa dongosolo la APU ya batri ya AGM. Kuphatikiza apo, nthawi yogwirira ntchito ndiye funso lalikulu lomwe madalaivala ndi magulu ankhondo amakhala nalo pa ma APU amagetsi. Pafupifupi, nthawi yogwirira ntchito ya APU yamagetsi yonse ndi maola 6 mpaka 8. Izi zikutanthauza kuti, thirakitala ingafunike kuyatsidwa kwa maola angapo kuti mabatire ayambe kugwira ntchito.
Posachedwapa RoyPow yatulutsa galimoto ya batri ya lithiamu-ion imodzi yotchedwa All-Electric Power Unit (Auxiliary Power Unit). Poyerekeza ndi mabatire achikhalidwe a lead-acid, mabatire a LiFePO4 awa ndi opikisana kwambiri pankhani ya mtengo, nthawi yogwirira ntchito, kugwiritsa ntchito bwino mphamvu, kukonza komanso kuteteza chilengedwe. Teknoloji yatsopano ya batri ya lithiamu All-Electric APU (Auxiliary Power Unit) yakonzedwa kuti ithetse zofooka za mayankho a APU a dizilo ndi magalimoto amagetsi omwe alipo. Chosinthira chanzeru cha 48V DC chimaphatikizidwa mu dongosololi, pamene galimoto ikuyenda pamsewu, chosinthira chimasamutsa mphamvu yamakina ya injini ya galimoto kupita ku magetsi ndikusungidwa mu batri ya lithiamu. Ndipo batri ya lithiamu imatha kuchajidwa mwachangu pafupifupi ola limodzi kapena awiri ndipo imapereka mphamvu ku HVAC nthawi zonse mpaka maola 12 kuti ikwaniritse kufunikira kwa magalimoto ataliitali. Ndi dongosololi, 90 peresenti ya ndalama zamagetsi zitha kuchepetsedwa kuposa kungokhala chete ndipo idagwiritsa ntchito mphamvu zobiriwira komanso zoyera m'malo mwa dizilo. Izi zikutanthauza kuti, padzakhala mpweya woipa 0 mumlengalenga ndi kuipitsa phokoso 0. Mabatire a lithiamu amadziwika ndi mphamvu zambiri zogwiritsira ntchito, nthawi yayitali yogwira ntchito komanso yosakonza, zomwe zimathandiza oyendetsa magalimoto kuti asadandaule ndi kusowa kwa mphamvu komanso mavuto okonza. Kuphatikiza apo, mphamvu yoziziritsira ya 48V DC air conditioner ya galimoto ya All-Electric APU (Auxiliary Power Unit) ndi 12000BTU/h, yomwe ili pafupi kwambiri ndi ma APU a dizilo.
Galimoto yatsopano ya batire ya lithiamu yoyera All-Electric APU (Auxiliary Power Unit) idzakhala njira yatsopano yomwe msika ukufuna m'malo mwa APU ya dizilo, chifukwa cha mtengo wake wotsika wamagetsi, nthawi yayitali yogwira ntchito komanso kusakhala ndi mpweya woipa.
Monga chinthu chopangidwa ndi "kuletsa injini ndi kuletsa kuimitsa magalimoto", makina onse a RoyPow a lithiamu ndi abwino komanso okhazikika pochotsa mpweya woipa, kutsatira malamulo oletsa kuimitsa magalimoto ndi kuimitsa magalimoto mdziko lonse, omwe akuphatikizapo zofunikira za California Air Resources Board (CARB), zomwe zapangidwa kuti ziteteze thanzi la anthu komanso kuthana ndi kuipitsidwa kwa mpweya m'boma. Kuphatikiza apo, kupita patsogolo kwaukadaulo wa mabatire kukuwonjezera nthawi yogwirira ntchito ya makina a nyengo, kuthandiza kuchepetsa nkhawa za ogula zokhudzana ndi nkhawa zamagetsi. Chomaliza koma chocheperako, chili ndi phindu lalikulu pakukweza kugona kwa oyendetsa magalimoto kuti achepetse kutopa kwa oyendetsa magalimoto m'makampani oyendetsa magalimoto.
