Ukukhetha i-Lithium yeBattery Management System (BMS) ibalulekile ekuqinisekiseni ukhuseleko, ukusebenza, kunye nobude benkqubo yebhetri yakho. Nokuba unika abathengi amandla ombane, iimoto zombane, okanye izisombululo zokugcina amandla, nasi isikhokelo esipheleleyo sokukunceda wenze isigqibo esinolwazi:
1. Misela iiNgcaciso zebhetri
Qala ngokuqonda ezona mpawu ziphambili zebhetri yakho ukuze uqinisekise ukuhambelana ne-BMS:
- Uhlobo Lwebhetri
Chonga ikhemistri yebhetri ye-lithium:I-Ternary Lithium (NCM/NCA),I-LiFePO4 (LFP), okanye abanye. Uhlobo ngalunye luneeprofayili zombane ezizodwa kunye neemfuno zokhuseleko.
Umzekelo: Iibhetri ze-Ternary lithium (3.7V nominal) zifuna ukhuseleko oluchanekileyo lwe-overcharge (≤4.25V), ngelixa i-LiFePO4 (3.2V nominal) isebenza ngokukhuselekileyo ukuya kwi-3.65V.
- Umthamo (Ah)
Tshatisa iiBMS'seqhubekayo kunye nencopho yokukhupha yangokukumthamo webhetri yakho. Iibhetri ezinomthamo ophezulu zifuna iiyunithi ze-BMS ezinamandla okuphatha ngoku.
- Uluhlu lwamandla ombane
Qinisekisa ukuba uluhlu lwamandla ombane lwe-BMS lugquma ibhetri yakhoamandla ombane aqhelekileyo,I-voltage yentlawulo epheleleyo, kwayeubuncinci bombane wokukhupha. Uluhlu olungahambelaniyo lomonakalo womngcipheko okanye ukunciphisa ukusebenza kakuhle.
I-BMS ethembekileyo kufuneka ikhusele kwaye yandise ukusebenza kwebhetri ngoku:
- uKhuseleko lwentlawulo egqithisiweyo
Icima ukutshaja ngokuzenzekelayo xa amandla ombane edlula imilinganiselo ekhuselekileyo (umzekelo, i-4.3V ye-ternary lithium).
- UKhuseleko lokuKhupha ngokuPheleleyo
Iyamisa ukukhutshwa ngaphambi kokuba i-voltage yehle ngaphantsi kwemilinganiselo ebalulekileyo (umzekelo, i-2.5V ye-lithium ye-ternary) ukuthintela ukuthotywa kweeseli.
- Ukhuseleko olugqithileyo kunye nolweSekethe emfutshane
Ifumanisa iisekethe ezigqithisileyo zangoku okanye ezimfutshane (ixesha lokuphendula: <100μs) ukuthintela ukubaleka kwe-thermal.
- Ukulinganisa iSeli
Ulungelelaniso olwenziwayoichitha amandla amaninzi njengobushushu (indleko-esebenzayo kwiipakethi ezincinci).
Ulungelelaniso olusebenzayoihambisa kwakhona amandla phakathi kweeseli (ezilungele iinkqubo ezinkulu, ukuphucula ubomi).
- Iimpawu eziphambili
UkuJonga iState-of-Charge (SOC).: Ukulandelela ngokuchanekileyo umthamo webhetri eseleyo.
Ulawulo lobushushu: Ubeka iliso kwaye ulawule ubushushu beeseli ukuthintela ukufudumeza.
IiNxibelelwano zoNxibelelwano: Ixhasa i-CAN ibhasi, i-UART, okanye iBluetooth yedatha yexesha langempela kunye nokuxilongwa.
3. Vavanya uMgangatho kunye nokuthembeka
Tyala imali kwi-BMS eqinisekisa ukuhlala kunye nokuthotyelwa:
- Iimpawu ezihloniphekileyo
Khetha abavelisi abasekiweyo abanobugcisa obuqinisekisiweyo kuyilo lwe-BMS kunye neziqinisekiso (umzekelo, UL, CE, ISO 26262 yeemoto).
- Yakha umgangatho
Umgangatho ophezuluIzinto zePCB, i-welding echanekileyo, kunye namacandelo e-premium (umzekelo, ii-MOSFET eziphezulu) ziqinisekisa uzinzo kunye nokusebenza kobushushu.
- Isoftware kunye ne-algorithms
Isoftware ye-BMS ephucukileyo yenza uqikelelo lwe-SOC oluchanekileyo, ukuxilongwa kwempazamo, kunye nohlaziyo lwe-firmware.
4. Tshatisa iiMfuno zokusiNgqongileyo kunye neSicelo
Lungisa ukhetho lwakho ngokwemiqathango yosetyenziso:
- Ubungakanani kunye nokudibanisa
Iiyunithi ze-BMS ezibambeneyo zilungele usetyenziso olubambeneyo kwindawo, ngelixa uyilo lweemodyuli lwenza lula ukukala kwiinkqubo zoshishino.
- Ukumelana Nobushushu
Khetha iiyunithi ze-BMS ezithelekelwe ubushushu obugqithisileyo (umzekelo, -40°C ukuya kwi-105°C) kusetyenziso lweemoto okanye ngaphandle.
- IiMfuno eziZodwa
Izisombululo ze-BMS zokungangeni manzi (IP67), zingangenwa luthuli, okanye zikwazi ukungcangcazela zikhulisa ukuthembeka kwimekobume erhabaxa.
Ukuqukumbela
Ukukhetha i-BMS ye-lithium efanelekileyo idinga ukulinganisa iinkcukacha zobugcisa, amandla okukhusela, ubukrelekrele besoftware, kunye nokuguquguquka kokusingqongileyo. I-BMS ehambelana kakuhle ayithinteli kuphela ukusilela kodwa yongeza ukusebenza kakuhle kwamandla kwaye yandisa ubomi bebhetri.
Ukufumana izisombululo ezilungiselelweyo, jonga iimveliso zethu ze-BMS eziqinisekisiweyo ezenzelwe usetyenziso lwebhetri ye-lithium eyahlukeneyo. Qhagamshelana neqela lethu ukuze ufumane umdlalo ogqibeleleyo kwiimfuno zakho!
