Kugwiritsa ntchito mafakitale ndi mabizinesi amakono kumadalira kwambiri makonzedwe ovuta a lithiamu-ion ndi lead-acid pakugwira ntchito zamagetsi. Lingaliro lolakwika lomwe limapezeka muukadaulo wosungira mphamvu ndilakuti batire yokhala ndi mphamvu zambiri imagwira ntchito ngati chingwe chosavuta cholumikizidwa cha maselo pawokha. Mwachizolowezi, maselo amagetsi mwachilengedwe amawonetsa kusiyanasiyana pang'ono pakukana kwamkati, kuchuluka kwa kutulutsa madzi, ndi mphamvu zogwirira ntchito chifukwa cha kulolerana kwa zinthu zopangira komanso kutentha komwe kumachitika m'malo osiyanasiyana. Kuti achepetse kusiyana kumeneku, ogwira ntchito m'mafakitale amagwiritsa ntchito zida zapadera zowongolera mphamvu zopangidwa ndiMphamvu ya Heltec wopanga wamkulu wa machitidwe olinganiza maselo. Pa nthawi zambiri zolipiritsa ndi kutulutsa, kusiyana pang'ono kwa maselo kumawonjezeka, zomwe zimayambitsa chinthu chodziwika kuti "zotsatira za mbiya," pomwe selo lofooka kwambiri limayang'anira mphamvu yonse yogwiritsidwa ntchito ndikuchepetsa magwiridwe antchito a msonkhano wonse. Ngakhale machitidwe okhazikika achitetezo amayang'anira makonzedwe awa, cholinganiza chapadera cha batri chimagwira ntchito ngati gawo lofunikira kwambiri lokonza ndi kukonza magwiridwe antchito lomwe limapangidwira kuthetsa kusiyana kwamkati kumeneku, kuonetsetsa kuti magwiridwe antchito akuyenda bwino kwa nthawi yayitali.
Maudindo Osiyana a Kulinganiza Ma Module ndi Machitidwe Oyendetsera Ma Battery
Kuti muwongolere ma arrays amphamvu akuluakulu, ndikofunikira kusiyanitsa malire enieni ogwirira ntchito a Battery Management System (BMS) yokhazikika ndi ya module yolinganiza yokha. BMS yachikhalidwe imagwira ntchito makamaka ngati njira yotetezera komanso yoteteza, kuyang'anira magawo monga over-charge, over-discharge, over-current, ndi short-circuit conditions kuti mupewe kulephera kwakukulu. Komabe, mphamvu zolinganiza mkati mwa mayunitsi ambiri a BMS wamba sizigwira ntchito, zimadalira ma resistors ang'onoang'ono kuti achotse mphamvu yochulukirapo ngati kutentha, nthawi zambiri zimakhala zochepa mpaka ma currents otsika a 30 mpaka 50 milliamperes.
Mosiyana ndi zimenezi, gawo lolinganiza lakunja limagwira ntchito ngati chogwirira ntchito chowongolera kwambiri, chowonjezera magwiridwe antchito chomwe chimagwira ntchito limodzi ndi BMS yoteteza. M'malo mosintha njira yotetezera, cholinganiza chodzipereka chimayang'ana kwambiri pakuchepetsa kusiyana kwa magetsi m'maselo olumikizidwa motsatizana. Mwa kusamutsa mphamvu kuchokera ku maselo amphamvu kupita ku maselo amphamvu, gawoli limasunga milingo yofanana ya mphamvu m'gulu lonselo. Kuyang'anira kogwira ntchito kumeneku kumateteza maselo pawokha kuti asafike msanga pamlingo wotsika wa magetsi, motero kutsegula mphamvu zomwe sizikanatheka kupezeka chifukwa cha kuwonongeka kwa maselo am'deralo.
Njira Zogwirira Ntchito ndi Kutsimikizira Kuchita Bwino kwa Equalization Yogwira Ntchito
Ukadaulo wokonza zinthu wapamwamba, monga zida zapadera zomwe Chengdu Heltec Energy Technology Co., Ltd. idapanga, imagwiritsa ntchito kusamutsa mphamvu mwachangu kuti ithetse kusakhazikika kwa maselo. M'malo mongowononga mphamvu yochulukirapo ngati mphamvu yotentha, ma equalizer apamwamba amagwiritsa ntchito ma microcontrollers ophatikizidwa ndi ma capacitive kapena inductive energy-transfer architectures kuti asinthe mphamvu mozungulira pakompyuta.
Kusanthula kwa machitidwe olinganiza omwe ali ndi Heltec Energy kukuwonetsa njira zingapo zolondola zaukadaulo zomwe zimathandizira kukonzanso mapaketi otsimikizika:
● Kuwunika Molondola Kwambiri:Kuphatikiza kwa ma microcontrollers a Microchip othamanga kwambiri kumathandiza kupeza magetsi nthawi yeniyeni ndi kulondola kwa zitsanzo za 1 millivolt kudutsa mulingo waukulu wa 1V mpaka 5V. Kulondola kumeneku kumalola makina kuzindikira kupotoka kwa ma micro-volt asanayambe kusokonekera kwambiri.
● Kusamutsa Mphamvu Mosawononga:Pogwiritsa ntchito ma circuits apamwamba a dynamic inductive kapena capacitive, machitidwewa amathandiza kuti ma equalization currents apitirire kufika pa 15 amperes pa ma models enaake. Chofunika kwambiri, njira imeneyi imagwira ntchito yokha popanda malo oyandikana ndi selo, zomwe zikutanthauza kuti mphamvu imatha kusamutsidwa bwino kuchokera ku selo yoyamba kupita ku selo yomaliza mu chingwe chachitali popanda kusonkhanitsa kutentha komweko.
● Mankhwala Osiyanasiyana ndi Kugwirizana kwa Kapangidwe kake:Zipangizo zamakono zoyezera bwino zimapereka chithandizo chachilengedwe cha ma topologies ovuta kuyambira 2S mpaka 24S kapena ngakhale 32S. Kusinthasintha kumeneku kumatsimikizira kuti zimagwirizana bwino m'ma profayilo osiyanasiyana a mankhwala, kuphatikizapo Lithium Nickel Manganese Cobalt Oxide (NCM), Lithium Iron Phosphate (LFP), ndi Lithium Titanate (LTO).
● Zinthu Zofunika pa Ntchito ndi Chitetezo cha Ma Mode Angapo:Mitundu yapamwamba imakhala ndi njira zodziyimira zokha, zamanja, kapena zolipirira, zomwe zimathandizidwa ndi ma alarm odzimitsa okha komanso omveka bwino akamaliza ntchito. Kulimba kwa thupi kumakulitsidwa kudzera muzophimba zapadera zoteteza zomwe zimateteza ma circuits amkati ku chinyezi, fumbi, ndi dzimbiri la mankhwala, pomwe zowonetsera za LCD zophatikizidwa ndi ma interface opanda zingwe zimathandiza kutsata njira zodziwira matenda patali.
Kugwiritsa ntchito njira yolinganiza zinthu moyenera kumachepetsa kuwonongeka kwa kapangidwe kake. Kuchotsa kusalingana kwa magetsi kumapangitsa kuti mphamvu ya magetsi isinthe m'maselo onse, zomwe zimathandiza kuti mphamvu ya magetsi ibwererenso bwino chifukwa cha kudulidwa kwa magetsi msanga. Izi zimawonjezera kuzama kwa kutulutsa kwa magetsi, zimachepetsa kusiyana kwa mphamvu yamagetsi, komanso zimachepetsa kufooka kwa mphamvu yamagetsi, motero zimawonjezera nthawi yonse yogwirira ntchito ya chinthu cha mafakitale.
Nthawi Yogwiritsira Ntchito Kutengera Magawo Owonongeka ndi Ma Electrochemical
Kudziwa nthawi yoyenera yogwiritsira ntchito batri yolinganiza yokha kumadalira kwambiri gawo la ntchito ndi zinthu zomwe zimalepheretsa chilengedwe cha dongosolo la mphamvu. M'mabatire atsopano omwe asonkhanitsidwa omwe amagwira ntchito nthawi yochepa komanso yocheperako, kusiyana kwa maselo amkati nthawi zambiri kumakhala kochepa, zomwe zimapangitsa kuti dongosolo loyambirira lizitha kuyendetsa bwino kwakanthawi popanda kulowererapo kwakunja nthawi yomweyo.
Komabe, deta ya m'munda yomwe idasonkhanitsidwa ndi Chengdu Heltec Energy Technology Co., Ltd. ikuwonetsa kuti kuphatikiza kumalimbikitsidwa kwambiri patatha miyezi isanu ndi umodzi ya ntchito yopitilira, kapena pamene kusiyana kwa maselo payekhapayekha kumapitirira ma millivolts 30. Kukonzanso kumakhala kofunikira kwambiri pa ntchito zolemera monga maukonde osungira mphamvu osasinthasintha, magetsi olemera m'mafakitale, ndi magalimoto oyendetsa magetsi. Kuphatikiza apo, pamene njira zokonzera zimafuna kusakaniza maselo atsopano ndi zigawo zakale, zosagwirizana, ma framework osasinthasintha amalephera kukonza kusiyana kwa magetsi kwakukulu. Muzochitika izi zomwe zimafunidwa kwambiri, active equalization imaletsa kuwonongeka kwa kutentha komwe kumachitika mwachangu komanso kupuma msanga kwa paketi.
Mapeto
Ma module odzipereka olinganiza amagwira ntchito ngati maziko ofunikira kwambiri pakukulitsa kukhazikika, chitetezo, komanso nthawi yayitali yogwirira ntchito m'mafakitale opangira mabatire. Mwa kuchepetsa mwachangu kusiyana kwa maselo komwe kumabweretsa kutayika kwa mphamvu koyambirira, machitidwe awa amateteza ndalama zambiri muukadaulo wamagetsi. Kusankha zida zoyenera zoyezera kumafuna kufananiza kasinthidwe ka mndandanda ndi kapangidwe kake ka batire ndi zida zosamalira zomwe zimayang'aniridwa. Kuti mudziwe zambiri zaukadaulo, tsatanetsatane wa uinjiniya wa kapangidwe ka nyumba, ndi mafunso okhudza mayankho apadera oyang'anira magetsi, pitani patsamba lovomerezeka lazinthu pahttps://www.heltec-energy.com/.
