Lingaliro lacell balancingmwina ndizodziwika kwa ambiri a ife. Izi zili choncho makamaka chifukwa kusasinthasintha kwamakono kwa maselo sikokwanira, ndipo kusanja kumathandiza kuti izi zitheke. Monga momwe simungapeze masamba awiri ofanana padziko lapansi, simungapezenso maselo awiri ofanana. Chifukwa chake, pamapeto pake, kulinganiza ndikuthana ndi zofooka za maselo, kukhala ngati chiwongola dzanja.
Ndi Zinthu Ziti Zomwe Zimawonetsa Kusagwirizana Kwa Maselo?
Pali mbali zinayi zazikulu: SOC (State of Charge), kukana kwamkati, kudziletsa pakali pano, komanso kuthekera. Komabe, kulinganiza sikungathetseretu kusagwirizanaku zinayizi. Kulinganiza kumatha kubweza kusiyana kwa SOC, mwamwayi kuthana ndi kusagwirizana kodziletsa. Koma kwa kukana kwamkati ndi mphamvu, kulinganiza kulibe mphamvu.
Kodi Kusagwirizana Kwa Maselo Kumayambika Bwanji?
Pali zifukwa ziwiri zazikulu: chimodzi ndi kusagwirizana komwe kumachitika chifukwa cha kupanga ndi kukonza ma cell, ndipo china ndi kusagwirizana komwe kumachitika chifukwa cha malo ogwiritsira ntchito selo. Kusagwirizana kwa kupanga kumachokera kuzinthu monga njira zogwirira ntchito ndi zipangizo, zomwe ndi kuphweka kwa nkhani yovuta kwambiri. Kusagwirizana kwa chilengedwe n'kosavuta kumvetsa, popeza malo a selo lililonse mu PACK ndi osiyana, zomwe zimapangitsa kusiyana kwa chilengedwe monga kusinthasintha pang'ono kwa kutentha. M'kupita kwa nthawi, kusiyana kumeneku kumachulukana, kumayambitsa kusagwirizana kwa maselo.
Kodi Balancing Imagwira Ntchito Motani?
Monga tanena kale, kusanja kumagwiritsidwa ntchito kuthetsa kusiyana kwa SOC pakati pa maselo. Moyenera, imasunga SOC ya cell iliyonse kukhala yofanana, kulola ma cell onse kuti afikire malire apamwamba ndi otsika ndikutulutsa nthawi imodzi, motero amawonjezera mphamvu yogwiritsira ntchito batire. Pali zochitika ziwiri za kusiyana kwa SOC: imodzi ndi pamene mphamvu zama cell zimakhala zofanana koma ma SOC ndi osiyana; chinacho ndi pamene mphamvu zama cell ndi ma SOC onse ali osiyana.
Chochitika choyamba (chakumanzere kwenikweni m'chithunzichi) chikuwonetsa ma cell omwe ali ndi mphamvu zofanana koma ma SOC osiyanasiyana. Selo yokhala ndi SOC yaying'ono kwambiri imafikira malire otulutsa koyamba (poganiza kuti 25% SOC ngati malire apansi), pomwe selo lomwe lili ndi SOC yayikulu limafikira malire oyamba. Ndi kusanja, ma cell onse amakhala ndi SOC yofanana panthawi yolipira ndi kutulutsa.
Chochitika chachiwiri (chachiwiri kuchokera kumanzere mu chithunzi chomwe chili pansipa) chimakhudza maselo omwe ali ndi mphamvu zosiyana ndi ma SOC. Apa, selo ndi ang'onoang'ono mphamvu mlandu ndi kutulutsa poyamba. Ndi kusanja, ma cell onse amakhala ndi SOC yofanana panthawi yolipira ndi kutulutsa.
Kufunika Kogwirizanitsa
Kulinganiza ndi ntchito yofunikira pama cell apano. Pali mitundu iwiri ya kusanja:kulinganiza mwachangundikungokhala chete kusanja. Kusanjikiza kosalekeza kumagwiritsa ntchito zoletsa kutulutsa, pomwe kusanja mwachangu kumaphatikizapo kuthamanga kwapakati pakati pa ma cell. Pali kutsutsana kwina pa mawu awa, koma sitilowa mu izo. Kulinganiza kosagwira ntchito kumagwiritsidwa ntchito kwambiri pochita, pomwe kusanja mogwira mtima sikumakhala kofala.
Kusankha Balancing Current kwa BMS
Pa nkhani ya kusakhazikika, kodi mphamvu yoyendera iyenera kudziwidwa bwanji? Moyenera, iyenera kukhala yayikulu momwe ndingathere, koma zinthu monga mtengo, kutayika kwa kutentha, ndi malo zimafunikira kusagwirizana.
Musanasankhe kusanja pakali pano, ndikofunikira kumvetsetsa ngati kusiyana kwa SOC ndi chifukwa cha chochitika chimodzi kapena ziwiri. Nthawi zambiri, ndi pafupi ndi chochitika chimodzi: maselo amayamba ndi mphamvu yofanana ndi SOC, koma monga momwe amagwiritsidwira ntchito, makamaka chifukwa cha kusiyana kwa kudziletsa, SOC ya selo iliyonse imakhala yosiyana. Choncho, kuthekera kolinganiza kuyenera kuthetsa kusiyana kwa kudziletsa.
Ngati ma cell onse atakhala ndi kutulutsa kofanana, sikukanakhala kofunikira. Koma ngati pali kusiyana pakudziletsa pakali pano, kusiyana kwa SOC kudzabuka, ndipo kulinganiza ndikofunikira kuti kulipire izi. Kuonjezera apo, popeza nthawi yowerengera tsiku ndi tsiku imakhala yochepa pamene kudziletsa kumapitirira tsiku ndi tsiku, nthawiyo iyeneranso kuganiziridwa.
