Lithium BMS — sisitimu yekutarisira mabhatiri — ndiyo dunhu riri pakati pe lithium battery pack uye nzira dzinoita kuti lithium cells dzisashande. Chero pack yakakomba, ingave lithium-ion (NCM), LiFePO4, kana LTO (lithium titanate), ine imwe, uye kuitsanangura kunoenderana nezvisarudzo zvina: chemistry uye series count iyo inofanira kutsigira, continuous current yainofanira kutakura, kutaurirana kunobatanidza zvinodiwa neapplication, uye nzira yekuenzanisa inochengetedza masero akaenzana muhupenyu hwepack.
Peji rino rinotsanangura zvinoitwa nesystem yekutarisira mabhatiri yelithium-ion neLiFePO4 packs, uye sarudzo imwe neimwe inotevedzana, nematanho anotsanangurwa neDALY padanho rega rega.
Zvinoitwa neLithium BMS
BMS yega yega ye lithium ine dziviriro yekutanga: overcharge, over-discharge, overcurrent, tembiricha, uye short-circuit protection. Izvi hazvisi zvinhu zvepamusoro - ndizvo zvinotsanangurwa muchikamu chechigadzirwa. BMS inotarisa voltage yeboka rega rega uye current yepakiti uye tembiricha, uye inobvisa circuit huru kana kuverenga kupi zvako kwapfuura muganho wayo wekudzivirira; kupora kunotevera kana mamiriro ezvinhu adzokera kuhwindo rakachengeteka, nemaitiro chaiwo ekupora zvichienderana nerudzi rwekutadza.
Pamusoro peizvozvo, BMS yakangwara inowedzera chiyero chaunogona kuona uye marongero aunogona kuchinja: kuverenga kwemagetsi esero nesero, kufungidzira mamiriro echaji, kunyora nhoroondo, uye chinongedzo cheBluetooth kuapp yefoni yekutarisa uye kugadzirisa maparameter. Sarudzo ina dziri pazasi dzinosarudza kuti ndeipi bhodhi ine mabasa iwayo epakeji yako chaiyo.
Sarudzo 1 - Kuverengwa kweKemistri neNhevedzano
Chinyorwa chekutanga ndechekuti paki yacho yakagadzirwa nei. DALY's Smart BMS (A Series) inoshandisa dhizaini yepasi rose ye4–24S (masero mana kusvika makumi maviri nemana akatevedzana) ichifukidza matatu makuru emakemikari e lithium:
| Kemesitiri | Rudzi rweNhevedzano Runotsigirwa |
|---|---|
| LiFePO4 (LFP) | 4–8S / 7–17S / 7–24S |
| Lithium-ion (NCM) | 4–7S / 7–17S / 7–20S |
| LTO | 6–8S / 11–17S / 11–24S |
Mabasa maviri anoita kuti dhizaini yepasi rose ive inoshanda mukugadzirwa. Chemistry inogona kuchinjwa muDALY app nekudzvanya kamwe chete, saka bhodhi rimwe chete rinopa odha yeLFP mwedzi uno uye odha yeNCM mwedzi unouya. Uye huwandu hweseji hunoonekwa otomatiki mukati memasekonzi makumi mana nemashanu ekutanga kuvhurwa - hapana maDIP switches, hapana configuration yeyuniti - zvinoreva kuti 13S e-bike pack uye 16S 48V pack zvinogona kutumirwa kubva muBMS stock imwecheteyo.
Sarudzo 2 — Danho Remazuva Ano Rinoenderera Mberi
Chiyero chiripo parizvino ndicho chisarudzo chine mugumisiro wakananga wemutengo: kutsanangura zvakanyanya wobhadhara mhangura yausingamboshandisi; kutsanangura zvishoma uye BMS inodzima kana mutoro wacho wakakodzera. A Series inosanganisira matanho mana:
| Danho Razvino | Kuenderera mberi | Nhambwe yepamusoro-soro |
|---|---|---|
| 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 |
Macheki maviri anotsanangura tier. Chekutanga, enzanisa continuous rating ne load's sustained draw, kwete nameplate maximum yayo. Chechipiri, tarisa peak column uchienzaniswa ne surge events dze application — motor starts, inverter surges — nekuti ndiyo peak rating, kwete continuous speak, ndiyo inosarudza kana BMS ichifamba nepakati padzo. Kana zvinodiwa ne pack zvichidarika 400A continuous, iyomutsetse weBMS wemagetsi ane simba guruanotora nzvimbo.
Sarudzo 3 — Kutaurirana
Paketi inongodzivirira chete inenge yakakwana; paketi inoshuma inogona kutengeswa zviri nani. A Series inouya neUART mbiri, RS485, uye CAN senzvimbo dzakajairika, pamwe neBluetooth yakavakirwa mukati yeDALY app. Iyo application yako inoshandisa zvinoenderana nezviri kune rumwe rutivi rwewaya: ma inverter nema charger muma storage and mobility systems anowanzo tora RS485 kana CAN, nepo UART inowanzo shandira ma display units nema host controllers.
Mubvunzo unoshanda hausi wekuti "bhazi ripi rakanakisa" asi "chii chinoshandiswa nemudziyo unogamuchira" - uye nekuti ma interfaces ese matatu ari pabhodhi rimwe chete, modhi imwe chete yeBMS inovhara vatengi vari mumabhazi akasiyana pasina shanduko yehardware.
Sarudzo 4 — Kuenzanisa
Masero anopararira nekupatsanurwa kwemagetsi, uye nzira yekuenzanisa inosarudza kuti BMS inogona kugadzirisa kusvetuka kwakadii. A Series ine 100mA passive balancing seyakajairwa - yakakwana kuchengetedza masero matsva anoenderana zvakanaka mumutsara panguva yekushanda kwakajairika.
Kana masero achiramba akafanana — masero ane simba guru ane masero akapararira, ehupenyu hwechipiri, kana kuti mapaketi anotenderera zvakadzama zuva nezuva —T Series BMS inoshanda yekuyeraInofambisa simba pakati pemasero kusvika ku1A ichishandisa bidirectional transformer balancing, kuburikidza ne4-24S range yakafanana, mumatanho aripo kubva ku40A kusvika ku400A. Chigadziko che30A chine 0.5A inductive active balancing chinowanikwawo kune 12V LiFePO4 builds diki. Pfungwa yespecification iri nyore: passive balancing by default, active balancing apo masero, kwete current rating, ndiwo anogumira.
Kuisa Sarudzo Ina Pamwe Chete
Tsanangudzo yakazara ye lithium BMS inoverengwa seizvi: chemistry uye series count (semuenzaniso, 16S LiFePO4), continuous current ine peak check (semuenzaniso, 100A continuous / 150A peak), required interfaces (semuenzaniso, CAN to the inverter), uye balancing method (passive for new matched cells). Nema parameters mana iwayo akasimbiswa, bhodhi rinozvisarudzira — iyoMhando dzeSmart BMS (A Series)inofukidza huwandu hwakazara hwe4–24S / 40A–400A, uye T Series inofukidza huwandu hwakafanana nekushanda kwakarongeka.
Mibvunzo Inowanzo bvunzwa
Q1Ko modhi imwe chete yeBMS inogona kunyatso kwanisa kusvika pa4S kusvika pa24S here?
A Series inofukidza 4–24S kuburikidza nemagadzirirwo matatu emhando dzakasiyana (eLiFePO4: 4–8S, 7–17S, uye 7–24S). Mukati megadziriro, huwandu hwemagadzirirwo hunoonekwa otomatiki mukati memasekonzi makumi mana nemashanu ekutanga kuvhurwa - paketi ye13S neketi ye16S zvinoshandisa bhodhi rimwe chete pasina kuiswa nemaoko. Kubatsira kweinventory: magadzirirwo matatu anofukidza ma voltage epaketi kubva ku12V-class kusvika ku60V-class zvichikwira, pachinzvimbo chemodhi yakasiyana pamagetsi.
Q2Ndeupi musiyano uripo pakati pekuenzanisa zvinhu zvisina basa (passive balancing) nekuenzanisa zvinhu zvine simba (active balancing)?
Kuenzanisa kusingashande kunoburitsa simba rakawandisa kubva kumasero akakwirira sekupisa, pa100mA paA Series - yakakwana kumasero matsva akakodzerana zvakanaka. Kuenzanisa kunoshanda kunofambisa simba kubva kumasero akakwirira kuenda kumasero akaderera, kusvika ku1A paT Series - pamapaketi apo kuenderana kwemasero kunofamba nekukurumidza kupfuura kugona kwekugadzirisa kusingashande, senge masero ane simba guru kana ehupenyu hwechipiri.
Q3Ndingasarudza sei pakati pema "continuous current ratings" ne "peak current ratings"?
Taura chiyero chinoenderera mberi kubva pakudhonza kwemutoro kwenguva refu, uye simbisa chiyero chepamusoro-soro uchienzaniswa nezviitiko zvekukwira kwesimba senge kutanga kwemota. Kuongororwa kwese kunofanirwa kupasa: BMS inokura chete pamagetsi anoenderera mberi ichadzima panguva yekukwira kwesimba; imwe inokura chete pamakomo inotakura mari isingakoshi.
Nezve DALY
DALY inogadzira uye inogadzira masisitimu ekugadzirisa mabhatiri e lithium evagadziri vemapaketi, maOEM, uye vanobatanidza, nezvigadzirwa zvinoshandiswa munyika dzinopfuura 130. Yakavambwa muna 2015, DALY inopa kusimbiswa kweinjiniya isati yatengeswa uye rutsigiro rwekufananidza mapurojekiti ekugadzira.
