Kusankha bwino lithiamu Battery Management System (BMS) ndikofunikira kuti mutsimikizire chitetezo, magwiridwe antchito, komanso moyo wautali wamagetsi anu. Kaya mukugwiritsa ntchito magetsi ogula, magalimoto amagetsi, kapena njira zosungira mphamvu, nali chitsogozo chokwanira chokuthandizani kupanga chisankho mozindikira:
1. Dziwani Zambiri za Battery
Yambani ndikumvetsetsa zomwe batri yanu ili nayo kuti muwonetsetse kuti ikugwirizana ndi BMS:
- Mtundu wa Battery
Dziwani chemistry ya batri ya lithiamu:Ternary Lithium (NCM/NCA),LiFePO4 (LFP), kapena ena. Mtundu uliwonse uli ndi mbiri yapadera yamagetsi komanso zofunikira zachitetezo.
Chitsanzo: Mabatire a Ternary lithiamu (3.7V mwadzina) amafunikira chitetezo chokwanira chacharge (≤4.25V), pomwe LiFePO4 (3.2V mwadzina) imagwira ntchito motetezeka mpaka 3.65V.
- Mphamvu (Ah)
Gwirizanani ndi BMSmosalekeza ndi pachimake kutulutsa panopaku mphamvu ya batri yanu. Mabatire amphamvu kwambiri amafunikira mayunitsi a BMS okhala ndi mphamvu zogwira pakali pano.
- Mtundu wa Voltage
Tsimikizirani kuchuluka kwa ma voliyumu a BMS kutengera batri yanumwadzina voteji,voteji yonse,ndivoteji yocheperako. Kuwonongeka kwachiwopsezo kosagwirizana kapena kuchepa kwachangu.
BMS yodalirika iyenera kuteteza ndi kukhathamiritsa magwiridwe antchito a batri kudzera:
- Chitetezo Chowonjezera
Imadula zokha kutchaja mphamvu ikadutsa malire otetezeka (mwachitsanzo, 4.3V ya ternary lithiamu).
- Chitetezo Chowonjezera Kwambiri
Imayimitsa kutulutsa mphamvu isanatsike pansi pazigawo zovuta (mwachitsanzo, 2.5V ya ternary lithium) kuteteza kuwonongeka kwa maselo.
- Kutetezedwa kwanthawi yayitali komanso kwakanthawi kochepa
Imazindikira mabwalo amakono kapena afupiafupi (nthawi yoyankha: <100μs) kuti mupewe kuthamanga kwamafuta.
- Kulinganiza Maselo
Kusasinthasinthaamataya mphamvu yochulukirapo ngati kutentha (yotsika mtengo pamapaketi ang'onoang'ono).
Kulinganiza mwachanguimagawanso mphamvu pakati pa maselo (oyenera machitidwe akuluakulu, kupititsa patsogolo moyo).
- Zapamwamba Mbali
State-of-Charge (SOC) Monitoring: Imalondola molondola kuchuluka kwa batire yotsala.
Kuwongolera Kutentha: Imayang'anira ndikuwongolera kutentha kwa maselo kuti isatenthedwe.
Communication Interfaces: Imathandizira basi ya CAN, UART, kapena Bluetooth pazidziwitso zenizeni zenizeni komanso zowunikira.
3. Unikani Ubwino ndi Kudalirika
Ikani mu BMS yomwe imatsimikizira kulimba ndi kutsata:
- Ma Brand Odziwika
Sankhani opanga okhazikika omwe ali ndi ukadaulo wotsimikizika pakupanga ndi ziphaso za BMS (mwachitsanzo, UL, CE, ISO 26262 yamagalimoto).
- Pangani Ubwino
WapamwambaZithunzi za PCB, kuwotcherera mwatsatanetsatane, ndi zigawo za premium (mwachitsanzo, ma MOSFET ochita bwino kwambiri) zimatsimikizira kukhazikika ndi kutentha.
- Mapulogalamu ndi ma algorithms
Mapulogalamu apamwamba a BMS amathandizira kuyerekezera kolondola kwa SOC, kuzindikira zolakwika, ndi zosintha za firmware.
4. Kufananiza Zosowa Zachilengedwe ndi Ntchito
Sinthani zomwe mwasankha kuti zigwirizane ndi momwe mungagwiritsire ntchito:
- Kukula ndi Kuphatikiza
Magawo a Compact BMS amagwirizana ndi ntchito zomwe zili ndi malo, pomwe ma modular ma modular amathandizira kuchulukira kwamakina opanga mafakitale.
- Kupirira Kutentha
Sankhani mayunitsi a BMS ovotera kutentha kwambiri (monga -40°C mpaka 105°C) pagalimoto kapena panja.
- Zofunikira Zapadera
Mayankho a BMS osalowa madzi (IP67), osagwira fumbi, kapena osagwedezeka amathandizira kudalirika m'malo ovuta.
Mapeto
Kusankha BMS yoyenera ya lithiamu kumafuna kugwirizanitsa mfundo zaumisiri, mphamvu zotetezera, luntha la mapulogalamu, ndi kusinthasintha kwa chilengedwe. BMS yofananira bwino sikuti imangolepheretsa kulephera komanso imakulitsa mphamvu zamagetsi ndikuwonjezera moyo wa batri.
Kuti mupeze mayankho ogwirizana, onani zinthu zathu zotsimikizika za BMS zopangidwira ma batire a lithiamu osiyanasiyana. Lumikizanani ndi gulu lathu kuti mupeze masewera oyenera pazosowa zanu!
