Dongosolo la lithiamu BMS — njira yoyendetsera mabatire — ndi dera lomwe lili pakati pa paketi ya batire ya lithiamu ndi momwe maselo a lithiamu amalephera. Kapangidwe kalikonse ka paketi, kaya lithiamu-ion (NCM), LiFePO4, kapena LTO (lithium titanate), kamakhala ndi imodzi, ndipo kuifotokoza kumadalira zisankho zinayi: kuchuluka kwa mankhwala ndi mndandanda womwe iyenera kuthandizira, mphamvu yopitilira yomwe iyenera kunyamula, kulumikizana komwe kumalumikizana ndi zosowa za pulogalamuyo, ndi njira yolinganiza yomwe imasunga maselo molingana ndi moyo wa paketiyo.
Tsamba ili likufotokoza zomwe makina oyendetsera mabatire a lithiamu-ion ndi LiFePO4 packs amachita, kenako chilichonse mwa zisankho zinayi motsatizana, ndi magawo omwe DALY imaphimba pa sitepe iliyonse.
Kodi Lithium BMS Imachita Chiyani?
Lithium BMS iliyonse imakhala ndi chitetezo choyambira: chowonjezera mphamvu, chotulutsa mphamvu mopitirira muyeso, chowonjezera mphamvu, kutentha, ndi chitetezo chafupikitsa. Izi sizinthu zapamwamba - ndizo tanthauzo la gulu la zinthu. BMS imayang'anira magetsi a gulu lililonse la selo ndi mphamvu ndi kutentha kwa paketi, ndipo imachotsa magetsi akuluakulu pamene kuwerenga kulikonse kudutsa malire ake otetezera; kuchira kumachitika zinthu zikabwerera ku zenera lotetezeka, ndi momwe kuchira kumakhalira kutengera mtundu wa cholakwika.
Kuphatikiza pa maziko amenewo, BMS yanzeru imawonjezera muyeso womwe mungawone ndi makonda omwe mungasinthe: kuwerenga kwa voteji ya selo ndi selo, kuyerekezera momwe chaji ilili, kulemba mbiri, ndi ulalo wa Bluetooth ku pulogalamu ya foni kuti muwunikire ndikusintha magawo. Zisankho zinayi zomwe zili pansipa zimatsimikizira bolodi lomwe lili ndi ntchito zimenezo pa paketi yanu.
Chisankho 1 - Chiwerengero cha Chemistry ndi Mndandanda
Choyamba ndi chomwe phukusili lapangidwa. DALY's Smart BMS (A Series) imagwiritsa ntchito kapangidwe ka 4–24S (maselo 4 mpaka 24 mu mndandanda) komwe kumaphatikizapo mankhwala atatu akuluakulu a lithiamu:
| Ukadaulo | Mndandanda Wothandizidwa |
|---|---|
| LiFePO4 (LFP) | 4–8S / 7–17S / 7–24S |
| Lithium-ion (NCM) | 4–7S / 7–17S / 7–20S |
| LTO | 6–8S / 11–17S / 11–24S |
Ntchito ziwiri zimapangitsa kuti kapangidwe kake kakhale kothandiza popanga. Chemistry imatha kusinthidwa mu pulogalamu ya DALY podina kamodzi, kotero bolodi lomwelo limapereka oda ya LFP mwezi uno ndi oda ya NCM mwezi wamawa. Ndipo kuwerengera kwa mndandanda kumadziwika zokha mkati mwa masekondi 45 kuchokera pomwe idayatsidwa koyamba - palibe ma switch a DIP, palibe kusinthidwa kwa unit - zomwe zikutanthauza kuti paketi ya njinga yamagetsi ya 13S ndi paketi ya 16S 48V zitha kutumizidwa kuchokera ku BMS yomweyo.
Chisankho 2 — Gawo Lopitilira la Pakadali Pano
Chiyeso cha panopa ndi chisankho chomwe chili ndi zotsatira za mtengo mwachindunji: tchulani mopitirira muyeso ndipo mumalipira mkuwa womwe simunagwiritse ntchito; tchulani moperewera ndipo BMS imasiya kugwira ntchito mukalandira katundu wovomerezeka. Mndandanda wa A umakhudza 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 amatchula gawo. Choyamba, gwirizanitsani mlingo wopitilira ndi kukwera kosalekeza kwa katundu, osati kuchuluka kwake kwa dzina. Chachiwiri, onani gawo la peak motsutsana ndi zochitika za surge ya pulogalamuyo — kuyambitsa kwa mota, kukwera kwa inverter — chifukwa ndi mlingo wa peak, osati wopitilira, womwe umasankha ngati BMS imadutsamo. Pamene kufunikira kwa paketi kupitirira 400A kosalekeza,Mzere wa BMS wamagetsi amphamvu kwambiriamatenga ulamuliro.
Chisankho 3 — Kulankhulana
Phukusi lomwe limateteza lokha limakhala lokwanira; phukusi lomwe limalengeza limatha kugulitsidwa bwino. A Series imabwera ndi ma UART awiri, RS485, ndi CAN ngati ma interfaces wamba, komanso Bluetooth yomangidwa mkati ya pulogalamu ya DALY. Chimene pulogalamu yanu imagwiritsa ntchito chimadalira zomwe zili kumapeto kwa waya: ma inverter ndi ma charger mu makina osungira ndi oyenda nthawi zambiri amatenga RS485 kapena CAN, pomwe UART nthawi zambiri imapereka ma display units ndi ma host controllers.
Funso lofunika kwambiri si lakuti "basi iti yabwino kwambiri" koma "chipangizo cholandirira chimalankhula chiyani" — ndipo chifukwa chakuti ma interfaces onse atatu ali pa bolodi limodzi, chitsanzo chimodzi cha BMS chimaphimba makasitomala m'mabasi osiyanasiyana popanda kusintha zida.
Chisankho 4 — Kulinganiza
Maselo amayendayenda mosiyanasiyana panthawi yamagetsi, ndipo njira yolinganiza imatsimikiza kuchuluka kwa kusuntha komwe BMS ingakonze. A Series imakhala ndi 100mA passive balancing monga muyezo - yokwanira kugwirizira maselo atsopano ofanana bwino pamzere nthawi zonse.
Pamene kusinthasintha kwa maselo kuli choletsa — maselo okhala ndi mphamvu yayikulu okhala ndi maselo ofalikira, maselo achiwiri, kapena mapaketi omwe amazungulira mozama tsiku lililonse —BMS yogwira ntchito yolinganiza ya T SeriesImasuntha mphamvu pakati pa maselo mpaka 1A pogwiritsa ntchito bidirectional transformer balancing, kudutsa 4–24S yomweyo, m'magawo amakono kuyambira 40A mpaka 400A. Gawo la 30A lokhala ndi 0.5A inductive active balancing likupezekanso pakupanga kwa 12V LiFePO4 kakang'ono. Mfundo yofotokozera ndi yosavuta: passive balancing mwachisawawa, active balancing pamene maselo, osati current rating, ndi omwe ali ndi malire.
Kuyika Zisankho Zinayi Pamodzi
Mafotokozedwe athunthu a lithiamu BMS amawerengedwa motere: kuchuluka kwa mankhwala ndi mndandanda (monga, 16S LiFePO4), mphamvu yopitilira ndi peak check (monga, 100A continuous / 150A peak), ma interfaces ofunikira (monga, CAN kupita ku inverter), ndi njira yolinganiza (yopanda ntchito ya maselo atsopano ofanana). Ndi magawo anayi amenewo okhazikika, bolodi limasankha lokha —Mitundu ya Smart BMS (A Series)imaphimba mitundu yonse ya 4–24S / 40A–400A, ndipo T Series imaphimba mitundu yomweyi ndi kulinganiza kogwira ntchito.
Mafunso Ofunsidwa Kawirikawiri
Q1Kodi mtundu umodzi wa BMS ungakwaniritsedi 4S mpaka 24S?
Mndandanda wa A umaphimba 4–24S kudzera m'makonzedwe atatu a mndandanda (a LiFePO4: 4–8S, 7–17S, ndi 7–24S). Mkati mwa kasinthidwe, kuwerengera kwa mndandanda kumadziwika zokha mkati mwa masekondi 45 kuchokera pamene magetsi oyamba kuyatsidwa — paketi ya 13S ndi paketi ya 16S zimagwiritsa ntchito bolodi lomwelo popanda kukhazikitsa pamanja. Ubwino wa zinthu zomwe zili m'sitolo: makonzedwe atatu amaphimba ma voltage a paketi kuyambira 12V-class mpaka 60V-class ndi kupitirira apo, m'malo mwa chitsanzo chosiyana pa voltage iliyonse.
Q2Kodi kusiyana pakati pa kulinganiza zinthu mopanda chidwi ndi kuchita zinthu mogwira mtima n'chiyani?
Kulinganiza zinthu mopanda mphamvu kumachotsa mphamvu yochulukirapo kuchokera ku maselo apamwamba kwambiri ngati kutentha, pa 100mA pa A Series — yokwanira maselo atsopano ofanana bwino. Kulinganiza zinthu mopanda mphamvu kumasuntha mphamvu kuchokera ku maselo apamwamba kupita ku maselo otsika, mpaka 1A pa T Series — pa ma paketi omwe kusinthasintha kwa maselo kumapita mofulumira kuposa momwe kukonza mopanda mphamvu kungagwirire, monga maselo okhala ndi mphamvu yayikulu kapena maselo achiwiri.
Q3Kodi ndingasankhe bwanji pakati pa ma rating a continuous ndi peak current?
Tchulani kuchuluka kwa mphamvu zomwe zimachokera ku mphamvu zomwe zimakokedwa ndi katundu, ndipo tsimikizirani kuchuluka kwa mphamvu zomwe zimachokera ku mphamvu zomwe zimachokera ku mphamvu zomwe zimayikidwa pa injini. Macheke onsewa ayenera kuvomerezedwa: mphamvu ya BMS yokha pa mphamvu zomwe sizimayikidwa pa mphamvu zomwe zima ...
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 wogulitsidwa kale komanso chithandizo chofananiza mapulojekiti opanga.
Mukufuna mtengo wa phukusi lanu la Lithium?
Fotokozani zisankho zinayi zomwe mwafunsa — gulu laukadaulo la DALY limayankha ndi chitsimikizo cha uinjiniya cha makonzedwe wamba mkati mwa tsiku limodzi lantchito.
- Kuchuluka kwa mankhwala ndi mndandanda (monga, 16S LiFePO4 / 13S NCM)
- Mphamvu yopitilira yofunikira komanso katundu uliwonse wofunikira wa pachimake
- Kulumikizana kumalumikizana ndi zosowa za pulogalamu (UART / RS485 / CAN)
