Intshayelelo
Ukukhetha umlinganiselo wangoku wenkqubo yokulawula ibhetri (BMS) kwibhetri yokugcina amandla ekhaya akuyonto nje yokufanisa iBMS nomthamo webhetri kwiiyure ze-amp (Ah). Indawo yokuqala eluncedo ngakumbi ngumbane ophezulu ekufuneka ipaki yebhetri iwuzise okanye iwamkele ngexesha lokusebenza okuqhelekileyo, kubandakanya isiphumo samandla e-inverter, i-voltage yebhetri, kunye nokusebenza kakuhle kokuguqula.
Umzekelo, umthengi one-inverter ye-kilowatt (kW) ezi-5 unokucinga ukuba i-100 ampere (A) BMS yanele ibhetri yeklasi ye-48-volt. Loo ngcinga isenokuba ayichanekanga ukuba i-voltage yebhetri iwela phantsi komthwalo okanye ukuba i-inverter isebenza kufutshane nemveliso yayo elinganisiweyo ixesha elide.
Esi sikhokelo sichaza indlela yokuqikelela umbane ophumayo ecaleni kwebhetri, indlela yokujonga umbane wokutshaja ngokwahlukeneyo, kunye nendlela yokuthelekisa iziphumo novavanyo lwamandla oluqhubekayo lweemodeli ze-DALY's 4th Generation LK kunye ne-LM home energy storage BMS.
1. Qala ngeBattery-Side Current, kungekuphela nje ngeAh Rating
Umthamo webhetri, olinganiswa ngee-amp-hours (Ah), uchaza ukuba ibhetri inokugcina itshaja engakanani phantsi kweemeko ezithile. Ayikuxeleli, ngokwayo, ukuba ibhetri ifanele iwuthumele kwi-inverter.
Ibhetri ye-100 Ah ingasetyenziswa ngamanqanaba ahlukeneyo ombane we-inverter kunye neeprofayili zokusebenza. Umbane we-BMS ofunekayo ke ngoko uxhomekeke kwimfuno yamandla yenkqubo kunye nevolthi yokusebenza yebhetri, kunye nemida yeeseli kunye nayo yonke inkqubo yombane.
Kwi-inverter enika amandla e-alternating-current (AC) kwibhetri, qikelela i-direct-current (DC) current ethathwe kwibhetri usebenzisa:
- IDC= umlinganiselo oqikelelweyo we-DC current otsalwa kwibhetri, kwii-amperes (A)
- PAC= amandla okukhupha i-AC e-inverter, kwiiwatts (W)
- Vibhetri= i-voltage yebhetri kwimeko yokusebenza evavanywayo, kwii-volts (V)
- η = ukusebenza kakuhle kokuguqulwa kwe-inverter okuchazwe njengedesimali (umzekelo, 90% = 0.90)
Olu luqikelelo lwendlela yokukhupha. Sebenzisa iinkcukacha zomenzi we-inverter zamandla okukhupha alinganisiweyo, ukusebenza kakuhle, kunye ne-voltage yebhetri ephantsi yokusebenza naphi na apho ikhoyo. Ubalo olusebenzisa i-voltage yebhetri eqhelekileyo lodwa lunokunciphisa umbane xa i-voltage yebhetri iphantsi.
2. Umzekelo oSebenzayo: I-Inverter ye-5 kW kwiBhetri ye-V-Class engama-48
Umzekelo olandelayo ubonisa, awungomzekelo webhetri-voltage jikelele. Masithi i-inverter kufuneka inike ii-watts ezingama-5,000 (W) AC, i-voltage yebhetri kwindawo yokusebenza yi-44 volts (V), kwaye ukusebenza kakuhle kwe-inverter kuloo ndawo yokusebenza kucingelwa ukuba yi-90%. La maxabiso mabini okusebenza yimizekelo yokuqikelela, hayi iinkcukacha zemveliso ye-DALY.
Phantsi kwezi ziqikelelo zichaziweyo, umsinga wokukhupha umbane ecaleni kwebhetri oqikelelweyo umalunga ne-126 A. I-BMS ene-100 A continuous rating ayizukuhlangabezana nale meko yokusebenza ebaliweyo ukuba ibhetri kufuneka iqhubeke nokubonelela ngemveliso epheleleyo ye-5,000 W kwi-44 V eqikelelweyo kunye nokusebenza kakuhle kwe-90%. Ukhetho oluqhubekayo lwe-150 A lunokuba ngumviwa wovavanyo olongezelelweyo, kodwa aluvunywa ngokuzenzekelayo lolu balo.
