Dongosolo loyendetsera mabatire a BMS ndi chida champhamvu chowongolera moyo wa mabatire a dongosolo la dzuwa. Dongosolo loyendetsera mabatire a BMS limathandizanso kuonetsetsa kuti mabatirewo ndi otetezeka komanso odalirika. Pansipa pali kufotokozera mwatsatanetsatane kwa dongosolo la BMS ndi zabwino zomwe ogwiritsa ntchito amapeza.
Momwe Dongosolo la BMS Limagwirira Ntchito
BMS ya mabatire a lithiamu imagwiritsa ntchito kompyuta yapadera ndi masensa kuti iyang'anire momwe batire imagwirira ntchito. Masensa amayesa kutentha, kuchuluka kwa chaji, mphamvu ya batire, ndi zina zambiri. Kompyuta yomwe ili mu dongosolo la BMS imapanga mawerengedwe omwe amayang'anira kuyatsa ndi kutulutsa batire. Cholinga chake ndikuwongolera nthawi yogwiritsira ntchito makina osungira mabatire a dzuwa ndikuwonetsetsa kuti ndi otetezeka komanso odalirika kugwira ntchito.
Zigawo za Dongosolo Loyang'anira Mabatire
Dongosolo loyang'anira mabatire a BMS lili ndi zigawo zingapo zofunika zomwe zimagwira ntchito limodzi kuti zigwire bwino ntchito kuchokera ku paketi ya mabatire. Zigawo zake ndi izi:
Chojambulira Batri
Chojambulira chimayika mphamvu mu batire pa voltage yoyenera komanso liwiro loyenera kuti chitsimikizire kuti chayikiridwa bwino.
Chowunikira Batri
Chowunikira batire ndi gulu la masensa omwe amawunika thanzi la mabatire ndi zina zofunika monga momwe amalipirira komanso kutentha.
Chowongolera Mabatire
Chowongolera chimayang'anira kuyitanitsa ndi kutulutsa batire. Chimaonetsetsa kuti magetsi alowa ndikutuluka bwino mu batire.
Zolumikizira
Zolumikizira izi zimalumikiza makina a BMS, mabatire, inverter, ndi solar panel. Zimaonetsetsa kuti BMS ili ndi mwayi wopeza chidziwitso chonse kuchokera ku makina a solar.
Makhalidwe a BMS Battery Management System
BMS iliyonse ya mabatire a lithiamu ili ndi mawonekedwe ake apadera. Komabe, zinthu ziwiri zofunika kwambiri ndikuteteza ndikuwongolera mphamvu ya batire. Chitetezo cha batire chimatheka poonetsetsa kuti batire imatetezedwa ndi magetsi komanso kutentha.
Chitetezo chamagetsi chimatanthauza kuti makina oyendetsera mabatire adzazimitsidwa ngati malo ogwirira ntchito otetezeka (SOA) apitirira. Chitetezo cha kutentha chingakhale chogwira ntchito kapena chopanda kutentha kuti batire likhale mkati mwa SOA yake.
Ponena za kasamalidwe ka mphamvu ya batri, BMS ya mabatire a lithiamu idapangidwa kuti iwonjezere mphamvu. Batire lidzakhala lopanda ntchito ngati kasamalidwe ka mphamvu sikuchitika.
Chofunika pakuwongolera mphamvu ya batri ndichakuti batri iliyonse mu paketi ya batri ikhale ndi magwiridwe antchito osiyana pang'ono. Kusiyana kwa magwiridwe antchito kumeneku kumaonekera kwambiri pa kuchuluka kwa kutayikira kwa madzi. Batri ikangoyamba kugwiritsidwa ntchito, paketiyo imatha kugwira ntchito bwino kwambiri. Komabe, pakapita nthawi, kusiyana kwa magwiridwe antchito a batri kumakula. Chifukwa chake, kungayambitse kuwonongeka kwa magwiridwe antchito. Zotsatira zake zimakhala mikhalidwe yosatetezeka yogwirira ntchito ya paketi yonse ya batri.
Mwachidule, njira yoyendetsera batire ya BMS idzachotsa mphamvu yolipirira m'maselo omwe ali ndi mphamvu zambiri, zomwe zimaletsa kudzaza kwambiri. Zimathandizanso kuti maselo omwe ali ndi mphamvu zochepa alandire mphamvu yolipirira yowonjezera.
BMS ya mabatire a lithiamu idzatumizanso mphamvu yochaja yozungulira maselo omwe ali ndi mphamvu. Chifukwa chake, maselo omwe ali ndi mphamvu yochepa amalandira mphamvu yochaja kwa nthawi yayitali.
Popanda njira yoyendetsera mabatire a BMS, maselo omwe amachaja poyamba amapitiliza kutchaja, zomwe zingayambitse kutenthedwa kwambiri. Ngakhale mabatire a lithiamu amapereka magwiridwe antchito abwino kwambiri, ali ndi vuto la kutenthedwa kwambiri akaperekedwa mphamvu yowonjezera. Kutenthetsa batire ya lithiamu kwambiri kumawononga magwiridwe antchito ake. Pazovuta kwambiri, zimatha kupangitsa kuti paketi yonse ya batire ilephere kugwira ntchito.
Mitundu ya BMS ya Mabatire a Lithium
Machitidwe oyendetsera mabatire akhoza kukhala osavuta kapena ovuta kwambiri pazochitika zosiyanasiyana zogwiritsira ntchito ndi ukadaulo. Komabe, onsewa cholinga chake ndi kusamalira paketi ya mabatire. Magulu odziwika kwambiri ndi awa:
Machitidwe a BMS Okhazikika
BMS yolumikizidwa pakati pa mabatire a lithiamu imagwiritsa ntchito njira imodzi yoyendetsera batire ya BMS pa paketi ya batire. Mabatire onse amalumikizidwa mwachindunji ku BMS. Phindu lalikulu la dongosololi ndilakuti ndi laling'ono. Kuphatikiza apo, ndi lotsika mtengo.
Vuto lake lalikulu ndilakuti popeza mabatire onse amalumikizana mwachindunji ndi chipangizo cha BMS, pamafunika ma doko ambiri kuti alumikizane ndi batire. Zotsatira zake zimakhala mawaya ambiri, zolumikizira, ndi mawaya. Mu batire lalikulu, izi zitha kusokoneza kukonza ndi kuthetsa mavuto.
BMS Yokhazikika ya Mabatire a Lithium
Monga BMS yolumikizidwa pakati, makina oyendetsera magetsi amalumikizidwa ku gawo lodzipereka la batire. Magawo a BMS a module nthawi zina amalumikizidwa ku module yoyamba yomwe imayang'anira momwe amagwirira ntchito. Ubwino waukulu ndikuti kuthetsa mavuto ndi kukonza kumakhala kosavuta. Komabe, vuto ndilakuti makina oyendetsera magetsi oyendetsera magetsi amawononga ndalama zambiri.
Machitidwe Ogwira Ntchito a BMS
Dongosolo logwira ntchito loyang'anira mabatire a BMS limayang'anira magetsi, mphamvu, ndi mphamvu ya paketi ya batire. Limagwiritsa ntchito izi kuwongolera kuyatsa ndi kutulutsa mphamvu kwa dongosololi kuti litsimikizire kuti paketi ya batireyo ndi yotetezeka kugwira ntchito ndipo limatero pamlingo woyenera.
Machitidwe a BMS Osasinthika
BMS yopanda mphamvu ya mabatire a lithiamu sidzayang'anira mphamvu ndi magetsi. M'malo mwake, imadalira nthawi yosavuta kuti ilamulire kuchuluka kwa mphamvu ndi kutulutsa mphamvu kwa paketi ya batire. Ngakhale kuti ndi njira yocheperako, imawononga ndalama zochepa kuti igulidwe.
Ubwino Wogwiritsa Ntchito BMS Battery Management System
Dongosolo losungira mabatire likhoza kukhala ndi mabatire angapo kapena mazana ambiri a lithiamu. Dongosolo losungira mabatire lotereli likhoza kukhala ndi mphamvu yamagetsi yofika pa 800V ndi mphamvu yamagetsi ya 300A kapena kuposerapo.
Kusayendetsa bwino paketi yamagetsi amphamvu chonchi kungayambitse mavuto aakulu. Motero, kukhazikitsa njira yoyendetsera mabatire a BMS ndikofunikira kuti pakhale batire yotetezeka. Ubwino waukulu wa BMS wa mabatire a lithiamu ukhoza kufotokozedwa motere:
Ntchito Yotetezeka
Ndikofunikira kuonetsetsa kuti batire yapakatikati kapena yayikulu ikugwira ntchito bwino. Komabe, ngakhale mayunitsi ang'onoang'ono monga mafoni amadziwika kuti amayaka moto ngati njira yoyenera yoyendetsera batire siyikidwa.
Kudalirika Kwambiri ndi Nthawi Yamoyo
Dongosolo loyang'anira mabatire limaonetsetsa kuti maselo omwe ali mkati mwa paketi ya batire akugwiritsidwa ntchito motetezeka. Zotsatira zake n'zakuti mabatire amatetezedwa ku mphamvu yamphamvu komanso kutulutsa mphamvu, zomwe zimapangitsa kuti pakhale dongosolo lodalirika la dzuwa lomwe lingapereke ntchito yodalirika kwa zaka zambiri.
Kuchuluka Kwambiri ndi Kuchita Bwino
BMS imathandiza kuyendetsa bwino mphamvu ya mayunitsi payokha mu paketi ya batri. Imaonetsetsa kuti mphamvu yabwino kwambiri ya paketi ya batri ikupezeka. BMS imayang'anira kusiyanasiyana kwa kutulutsa madzi, kutentha, ndi kutsika kwa madzi, zomwe zingapangitse kuti paketi ya batri ikhale yopanda ntchito ngati siilamulidwa.
Kuzindikira Matenda ndi Kulankhulana Kwakunja
BMS imalola kuyang'anira batire nthawi zonse komanso nthawi yeniyeni. Kutengera momwe imagwiritsidwira ntchito pakadali pano, imapereka ziwerengero zodalirika za thanzi la batire komanso nthawi yomwe ikuyembekezeka kukhalapo. Chidziwitso chodziwitsa matenda chomwe chaperekedwa chimatsimikiziranso kuti vuto lililonse lalikulu lizindikirika msanga lisanawonongeke. Malinga ndi ndalama, zingathandize kuonetsetsa kuti pakukonzekera bwino kusintha batire.
Ndalama Zochepetsedwa Pakapita Nthawi Yaitali
BMS imabwera ndi mtengo woyambira wokwera kwambiri kuposa mtengo wokwera wa paketi yatsopano ya batri. Komabe, kuyang'anira komwe kumachitika, komanso chitetezo chomwe BMS imapereka, zimatsimikizira kuti ndalama zomwe zimawonongeka pakapita nthawi zichepa.
Chidule
Dongosolo loyendetsera mabatire a BMS ndi chida champhamvu komanso chothandiza chomwe chingathandize eni ake a solar system kumvetsetsa momwe banki yawo ya mabatire imagwirira ntchito. Ingathandizenso kupanga zisankho zabwino zachuma pomwe ikukweza chitetezo cha paketi ya mabatire, moyo wautali, komanso kudalirika. Zotsatira zake n'zakuti eni ake a BMS ya mabatire a lithiamu amapindula kwambiri ndi ndalama zawo.
