Dongosolo loyang'anira mabatire a BMS ndi chida champhamvu chosinthira moyo wa mabatire a solar system. Njira yoyendetsera batire ya BMS imathandizanso kuonetsetsa kuti mabatire ndi otetezeka komanso odalirika. Pansipa pali kufotokozera mwatsatanetsatane kachitidwe ka BMS ndi maubwino omwe ogwiritsa ntchito amapeza.
Momwe BMS System imagwirira ntchito
BMS ya mabatire a lithiamu imagwiritsa ntchito makompyuta apadera ndi masensa kuti aziwongolera momwe batire imagwirira ntchito. Masensa amayesa kutentha, kuchuluka kwa ma charger, kuchuluka kwa batire, ndi zina zambiri. Kompyuta yomwe ili m'gulu la BMS imawerengera zomwe zimayang'anira kuyitanitsa ndi kutulutsa batire. Cholinga chake ndikuwongolera moyo wa makina osungira batire a dzuwa ndikuwonetsetsa kuti ndi otetezeka komanso odalirika kuti agwire ntchito.
Zigawo za Battery Management System
Dongosolo loyang'anira batire la BMS lili ndi zida zingapo zomwe zimagwirira ntchito limodzi kuti zipereke magwiridwe antchito abwino kuchokera pa paketi ya batri. Magawo ake ndi:
Chojambulira Battery
Chaja imalowetsa mphamvu mu paketi ya batri pamagetsi oyenera komanso kuthamanga kwamagetsi kuti iwonetsetse kuti yachajitsidwa bwino.
Battery Monitor
Chojambulira cha batri ndi chojambulira chomwe chimayang'anira thanzi la mabatire ndi zidziwitso zina zofunika monga momwe akulipirira komanso kutentha kwake.
Wowongolera Battery
Wowongolera amayang'anira kulipiritsa ndi kutulutsa kwa paketi ya batri. Zimatsimikizira kuti mphamvu imalowa ndikusiya batire paketi bwino.
Zolumikizira
Zolumikizira izi zimalumikiza dongosolo la BMS, mabatire, inverter, ndi solar panel. Imawonetsetsa kuti BMS ili ndi mwayi wodziwa zonse kuchokera ku solar system.
Zomwe zili mu BMS Battery Management System
BMS iliyonse yamabatire a lithiamu ili ndi mawonekedwe ake apadera. Komabe, zinthu zake ziwiri zofunika kwambiri ndikuteteza ndikuwongolera kuchuluka kwa paketi ya batri. Kutetezedwa kwa paketi ya batri kumatheka poonetsetsa chitetezo chamagetsi ndi chitetezo chamafuta.
Kutetezedwa kwamagetsi kumatanthauza kuti makina oyendetsera batire adzatsekedwa ngati malo ogwiritsira ntchito otetezeka (SOA) adutsa. Kutetezedwa kwamafuta kumatha kukhala kogwira ntchito kapena kuwongolera kutentha kuti musunge batire mkati mwa SOA yake.
Ponena za kasamalidwe ka batire, BMS ya mabatire a lithiamu idapangidwa kuti iwonjezere mphamvu. Batire paketi pamapeto pake idzakhala yopanda ntchito ngati kasamalidwe ka mphamvu sikunachitike.
Chofunikira pakuwongolera mphamvu ndikuti batire iliyonse mu paketi ya batri imakhala ndi magwiridwe antchito osiyana pang'ono. Kusiyanasiyana kwa magwiridwe antchitowa kumawonekera kwambiri pamitengo yotayikira. Ikakhala yatsopano, paketi ya batri imatha kugwira bwino ntchito. Komabe, pakapita nthawi, kusiyana kwa magwiridwe antchito a batri kumakula. Chifukwa chake, zimatha kuwononga magwiridwe antchito. Zotsatira zake ndizovuta kugwiritsa ntchito paketi yonse ya batri.
Mwachidule, dongosolo la kasamalidwe ka batri la BMS lidzachotsa ndalamazo m'maselo omwe amadzaza kwambiri, zomwe zimalepheretsa kuwonjezereka. Zimathandizanso kuti ma cell omwe salipiritsidwa pang'ono alandire ndalama zambiri.
BMS ya mabatire a lithiamu idzawongoleranso zina kapena pafupifupi zonse zomwe zikulipiritsa kuzungulira ma cell omwe adayimbidwa. Chifukwa chake, ma cell omwe salipiritsidwa pang'ono amalandira ma charger kwa nthawi yayitali.
Popanda dongosolo loyang'anira mabatire a BMS, ma cell omwe amalipira poyamba amapitilirabe, zomwe zingayambitse kutenthedwa. Ngakhale mabatire a lithiamu amapereka ntchito yabwino kwambiri, amakhala ndi vuto la kutentha kwambiri akamaperekedwa. Kutentha kwambiri batire ya lithiamu kumawononga kwambiri ntchito yake. Muzochitika zoipitsitsa, zingayambitse kulephera kwa paketi yonse ya batri.
Mitundu ya BMS ya Mabatire a Lithium
Makina owongolera mabatire amatha kukhala osavuta kapena ovuta kwambiri pamakagwiritsidwe ntchito osiyanasiyana ndi matekinoloje. Komabe, onsewa amafuna kusamalira batire paketi. Magulu odziwika kwambiri ndi awa:
Centralized BMS Systems
BMS yapakati yamabatire a lithiamu imagwiritsa ntchito kasamalidwe ka batire la BMS limodzi pa paketi ya batri. Mabatire onse amalumikizidwa mwachindunji ku BMS. Phindu lalikulu la dongosololi ndilokuti ndilokhazikika. Kuphatikiza apo, ndi yotsika mtengo.
Choyipa chake chachikulu ndikuti popeza mabatire onse amalumikizana ndi gawo la BMS mwachindunji, pamafunika madoko ambiri kuti agwirizane ndi paketi ya batri. Zotsatira zake ndi mawaya ambiri, zolumikizira, ndi ma cabling. Mu paketi yayikulu ya batri, izi zitha kusokoneza kukonza ndi kuthetsa mavuto.
Modular BMS ya Mabatire a Lithium
Monga BMS yapakati, modular system imalumikizidwa ndi gawo lodzipereka la paketi ya batri. Ma module a BMS nthawi zina amalumikizidwa ndi gawo loyambirira lomwe limayang'anira momwe amagwirira ntchito. Ubwino waukulu ndikuti kuthetsa mavuto ndi kukonza kumakhala kosavuta. Komabe, choyipa ndichakuti ma modular kasamalidwe ka batire amawononga ndalama zambiri.
Active BMS Systems
Dongosolo loyang'anira batire la BMS lomwe limagwira ntchito limayang'anira mphamvu ya batri, yapano, komanso mphamvu yake. Imagwiritsa ntchito chidziwitsochi kuwongolera kuyitanitsa ndi kutulutsa makinawo kuti zitsimikizire kuti paketi ya batri ndiyotetezeka kuti igwire ntchito ndipo imachita izi pamlingo woyenera.
Passive BMS Systems
BMS yokhazikika ya mabatire a lithiamu sichidzayang'anira zamakono ndi magetsi. M'malo mwake, imadalira chowerengera chosavuta kuti chiwongolere kuchuluka kwa kuchuluka kwa batire ndi kutulutsa kwa paketi. Ngakhale kuti ndi dongosolo lochepa kwambiri, zimawononga ndalama zochepa kuti mupeze.
Ubwino Wogwiritsa Ntchito BMS Battery Management System
Makina osungira mabatire amatha kukhala ndi mabatire angapo kapena mazana a lithiamu. Makina osungira mabatire otere amatha kukhala ndi voteji mpaka 800V ndi 300A kapena kupitilira apo.
Kunyalanyaza paketi yamagetsi okwera ngati imeneyi kungayambitse masoka aakulu. Chifukwa chake, kukhazikitsa kasamalidwe ka batire la BMS ndikofunikira kuti mugwiritse ntchito batire paketi mosamala. Ubwino waukulu wa BMS wamabatire a lithiamu unganene motere:
Ntchito Yotetezeka
Ndikofunikira kuwonetsetsa kuti batire ikugwira ntchito motetezeka papaketi yapakati kapena yayikulu. Komabe, ngakhale mayunitsi ang'onoang'ono ngati mafoni amadziwika kuti akugwira moto ngati dongosolo loyendetsa bwino la batri silinakhazikitsidwe.
Kudalirika Kwambiri Ndi Moyo Wathanzi
Dongosolo loyang'anira batire limatsimikizira kuti ma cell omwe ali mkati mwa batire paketi amagwiritsidwa ntchito mkati mwa magawo otetezedwa. Chotsatira chake ndi chakuti mabatire amatetezedwa ku chiwongoladzanja chaukali ndi kutulutsa, zomwe zimatsogolera ku dongosolo lodalirika la dzuwa lomwe lingapereke zaka za utumiki wodalirika.
Great Range ndi Magwiridwe
BMS imathandizira kuwongolera kuchuluka kwa mayunitsi omwe ali mu batire paketi. Zimatsimikizira kuti kuchuluka kwa batire kwapaketi kumakwaniritsidwa. BMS imayang'anira kusiyanasiyana kwa kudziletsa, kutentha, ndi kutsika kwapang'onopang'ono, zomwe zingapangitse kuti batire ikhale yopanda ntchito ngati siyiyendetsedwa.
Diagnostics ndi Kulankhulana Kwakunja
BMS imalola kuwunika mosalekeza, munthawi yeniyeni ya paketi ya batri. Kutengera ndikugwiritsa ntchito pano, imapereka kuyerekezera kodalirika kwa thanzi la batri komanso moyo womwe ukuyembekezeka. Zomwe zaperekedwa zimatsimikiziranso kuti vuto lililonse lalikulu lizindikirika msanga lisanakhale lowopsa. Kuchokera pamalingaliro azachuma, zingathandize kuonetsetsa kukonzekera koyenera m'malo mwa paketi.
Kuchepetsa Mtengo Kwa Nthawi Yaitali
BMS imabwera ndi mtengo wokwera wokwera pamwamba pa mtengo wapamwamba wa paketi yatsopano ya batri. Komabe, kuyang'anira kotsatira, ndi chitetezo choperekedwa ndi BMS, zimatsimikizira kuchepetsa ndalama kwa nthawi yaitali.
Chidule
Dongosolo loyang'anira mabatire a BMS ndi chida champhamvu komanso chothandiza chomwe chingathandize eni ma solar system kumvetsetsa momwe banki yawo imagwirira ntchito. Zingathandizenso kupanga zisankho zabwino zachuma ndikuwongolera chitetezo cha batri, moyo wautali, ndi kudalirika. Chotsatira chake ndi chakuti eni ake a BMS a mabatire a lithiamu amapindula kwambiri ndi ndalama zawo.
