"24V BMS" imafotokoza ma paketi awiri osiyana m'makemikolo akuluakulu, ndipo chisankho choyamba ndi chomwe mukumanga. Phukusi la lithiamu la 24V-class ndi 7S li-ion (NCM) — maselo asanu ndi awiri motsatizana, 25.2V nominal — kapena 8S LiFePO4, maselo asanu ndi atatu pa 25.6V nominal. Kemistri imasankha kuchuluka kwa maselo, ndipo kuchuluka kwa maselo kumasankha zomwe BMS iyenera kuthandizira. Smart BMS (A Series) ya DALY imaphimba zonse ziwiri pa kasinthidwe kofanana kotsika: 8S ili pamwamba pa 4–8S LiFePO4 range, ndi 7S pamwamba pa 4–7S li-ion range, m'magawo apano kuyambira 40A mpaka 400A.
Nayi kufanana kwa chiwerengero cha maselo a chemistry onse awiri, kutsatiridwa ndi momwe bolodi limodzi limawaphimbira ndi momwe mungakhazikitsire gawo lomwe lilipo.
Kuyerekeza Chiwerengero cha Maselo pa 24V
| Kumanga kwa 24V | Maselo Otsatizana | Voteji Yodziwika | Kutsimikizira Kapangidwe |
|---|---|---|---|
| LiFePO4 (LFP) | 8S | 25.6V | Kapangidwe ka LFP ka 4–8S ✓ — kapamwamba kwambiri |
| Li-ion (NCM) | 7S | 25.2V | Kapangidwe ka li-ion ya 4–7S ✓ — yapamwamba kwambiri |
Ma cell onsewa amawerengedwa pamwamba pa ma configuration ranges awo, ndipo onse awiri ndi zinthu wamba — palibe sitepe yapadera pa 8S LFP kapena 7S NCM. Ngati wogulitsa watchula chimodzi mwa zinthuzi ngati kapangidwe kapadera, dziwani kuti zonse ziwiri zili mkati mwa ma configuration otsika a DALY.
Bolodi Limodzi, Ma Chemistry Onse
Kwa wopanga mapaketi omwe amapereka maoda osiyanasiyana a 24V — LFP ya makasitomala a solar ndi othandizira, NCM komwe kuchuluka kwa mphamvu ndikofunikira — funso lothandiza ndi zinthu zomwe zili mumndandanda. Mndandanda wa A umayankha ndi ntchito ziwiri pa bolodi limodzi.
Mabatire amatha kusinthidwa mu pulogalamu ya DALY podina kamodzi kokha: bolodi lomwelo limagwira ntchito ngati 8S LFP BMS sabata ino ndi 7S NCM BMS sabata yamawa. Ndipo kuwerengera kwa mndandanda kumadziwika zokha mkati mwa masekondi 45 kuchokera pomwe idayatsidwa koyamba — palibe ma switch a DIP, palibe kasinthidwe ka pa unit — kotero bolodi limazindikira ngati lili pa maselo 7 kapena 8 popanda kuuzidwa.
Zotsatira zake ndi chitsanzo chimodzi chodzaza ndi mzere wonse wa 24V, malinga ndi momwe oda iliyonse ikufotokozera. Magawo onse ali ndi ma UART awiri, RS485, ndi CAN ngati ma interfaces wamba, komanso Bluetooth yomangidwa mkati mwa pulogalamu ya DALY.
Kukhazikitsa Gawo Lamakono
Mndandanda wa A umaphimba zomangamanga za 24V m'magawo anayi:
| Gawo Lapano | Mosalekeza | Nsonga |
|---|---|---|
| 40A / 60A | 40A / 60A | 60A / 90A |
| 80A / 100A | 80A / 100A | 120A / 150A |
| 150A / 200A | 150A / 200A | 225A / 300A |
| 250A–400A | 250A / 300A / 400A | 375A–600A |
Macheke awiri amakhazikitsa gawo, mosasamala kanthu za momwe ntchito ikuyendera. Gwirizanitsani kuchuluka kosalekeza ndi kuchuluka kwa katundu komwe kumayesedwa kosalekeza — ntchito zoyendera monga mipando yamagetsi ndi ma scooter nthawi zambiri zimakhala m'magawo otsika, pomwe katundu wa mafakitale wa 24V monga ma AGV (magalimoto oyendetsedwa ndi makina) amafika pamwamba, koma muyeso umaposa zomwe anthu amaganiza. Kenako onetsetsani kuti mulingo wa pamwamba ndi wofanana ndi zomwe zimachitika chifukwa cha kuchuluka kwa kukwera kwa katundu; ngati kuchuluka kwa kukwera kwa katundu kuyandikira denga la pamwamba la gawo, kwezani gawo limodzi.
Pa mabanki osungira mphamvu a 24V, gawo lolumikizana lomwe limamangidwa mkati limathandizira ma paketi 10 nthawi imodzi ndi chitetezo cha kulowa pakati pa ma paketi - kuchuluka kwa mphamvu komwe kumatuluka pamene paketi yatsopano ilumikizidwa kumakhala kochepa m'malo mopanda kulamulirika - kotero banki ya 24V imatha kukula paketi yoyamba itatha.
Pamene Kusasinthasintha kwa Selo Ndiko Choletsa
Mndandanda wa A uli ndi 100mA passive balancing monga muyezo, womwe umasunga maselo atsopano ofanana bwino muutumiki wabwinobwino. Kumene kukhazikika kwa maselo ndiko chinthu choletsa — maselo akuluakulu okhala ndi kufalikira kwakukulu, kapena maselo achiwiri —BMS yogwira ntchito yolinganiza ya T Seriesimaphimba ma 4–8S LFP ndi 4–7S li-ion omwewo ndi 1A bidirectional transformer balance pa ma tiers a 40A–400A.
Mafunso Ofunsidwa Kawirikawiri
Q1Kodi 24V BMS 7S kapena 8S ndi yotani?
Zonsezi zilipo, ndipo chemistry imasankha: 8S ya LiFePO4 (25.6V nominal), 7S ya li-ion NCM (25.2V nominal). Choyamba tchulani chemistry; chiwerengero cha maselo chimatsatira kuchokera pamenepo.
Q2Kodi bolodi limodzi la BMS lingathe kupereka maoda a 7S NCM ndi 8S LFP?
Inde — chemistry imatha kusinthidwa mu pulogalamu ya DALY, ndipo bolodi limazindikira kuchuluka kwa ma series enieni mkati mwa masekondi 45 kuchokera pamene magetsi oyamba kuyatsidwa. Mtundu umodzi wodzaza umaphimba mzere wonse wa 24V m'ma chemistry onse awiri.
Q3Kodi pulogalamu ya 24V ikufunika gawo liti lamakono?
Ikani kuchokera ku miyeso iwiri, osati kuchokera ku gulu logwiritsira ntchito: kukoka kopitilira kwa katundu kumayika gawo lopitilira, ndipo chochitika choyipa kwambiri cha surge chiyenera kuchotsa chiŵerengero cha peak cha tier. Ngati surge ifika pa denga la peak, kwerani pamwamba pa top imodzi.
Zokhudza DALY
DALY imapanga ndikupanga makina oyang'anira mabatire a lithiamu kwa opanga mapaketi, ma OEM, ndi ophatikiza, ndi zinthu zomwe zimagwiritsidwa ntchito m'maiko opitilira 130. DALY idakhazikitsidwa mu 2015, imapereka chitsimikizo cha uinjiniya chisanagulitsidwe komanso chithandizo chofananiza mapulojekiti opanga.
Mukupempha Mtengo wa Phukusi la 24V?
Funsani mafunso awa — Gulu la akatswiri la DALY limayankha ndi chitsimikizo cha uinjiniya cha makonzedwe oyenera mkati mwa tsiku limodzi la bizinesi.
- Kuchuluka kwa maselo ndi mankhwala (8S LiFePO4 / 7S NCM)
- Mphamvu yopitilira yofunikira, komanso chochitika choipa kwambiri cha kukwera kwa madzi ngati chafotokozedwa
- Kulumikizana kumalumikizana ndi zosowa za pulogalamu (UART / RS485 / CAN)
