Technology Definition
Indawo yokuhlala eneVoltage ephantsi BESS (≤ 60 V)
I-architecture esasazwayo apho iimodyuli zebhetri ze-40-60 V zihambelana kumgangatho wekhabhinethi. Iqonga elikwanti le-DC-DC ngaphakathi kwi-inverter ye-hybrid yongeza amandla ombane ebhetri kwi-DC-bus yangaphakathi, apho idityaniswa namandla e-PV ngaphambi kokuguqulwa.
I-BESS yeNdawo yokuHlala enoMbane oPhezulu (85–600 V)
Uyilo olusembindini, olucwangcisiweyo loluhlu: iimodyuli ezininzi ziqhagamshelwe kuthotho ukwenza umtya webhetri we-85-600 V. Ibhokisi yokulawula i-high-voltage (i-fuses edibeneyo, i-contactors, i-pre-charge kunye ne-isolation monitoring) ityisa umtya ngokuthe ngqo kwi-inverter's DC-bus ngokusebenzisa i-buck / boost regulator.
Uthelekiso lweNtsebenzo
Umbane ophantsi
IiPros
- Ulawulo lokhuseleko lwe-Extra-low-low-voltage (ELV); umngcipheko omncinci wokuchukumisa
- Ufakelo lwemodyuli, iplagi kunye nomdlalo; iCapEx esezantsi kumakhaya acinezelekileyo
- I-algorithms ye-BMS eyenziwe lula ehambelanayo
Ububi
- Ilahleko ephezulu yokuxhathisa (I²R) → 3–5 % isohlwayo samandla
- Amandla okukhupha alinganiselwe; ayilungelanga imithwalo engaphezu kwe-3 kW ezinzileyo
- Umthamo wexesha elide wokukhukuliseka kwiibhloko ezinxuseneyo kwandisa imijikelo yolondolozo
Umbane oPhezulu
IiPros
- Ukuya kuthi ga kwi-96% yokusebenza kakuhle kohambo lokuya nokubuya (RTE) sibulela kwimisinga esezantsi kunye nokunciphisa umthwalo we-thermal
- Imveliso eqhubekayo ye-5-10 kW; ixhasa i-HVAC, impompo yobushushu okanye ukufudumeza kwamanzi ngoko nangoko
- Amacandelwana amancinci anqamlezayo → ikhaphukhaphu, intambo yokubopha intambo ehlangeneyo kunye nemagnethi yokuguqula
Ububi
- Ifuna amagcisa e-HV aqinisekisiweyo; ngqongqo IEC 63056 / UL 9540A uvavanyo lomlilo
- I-voltage yenqanaba leseli engqongqo kunye nobushushu obuhambelanayo; i-BMS ephucukileyo enolungelelwaniso olusebenzayo
- Iindleko eziphezulu zangaphambili (ibhetri + nezixhobo zokhuseleko zeHV)
Iimeko zeSicelo
Umbane ophantsi
- Amagumbi amancinci / izindlu zempelaveki ezinomthwalo we-< 10 kWh wemihla ngemihla kwaye akukho zixhobo zombane eziphezulu
- Iipropathi zokulinga okanye ezirentisayo apho ukususwa ngokukhawuleza kuxatyiswa ngaphezu kokusebenza okuphezulu
Umbane oPhezulu
- Amakhaya aphakathi ukuya kumakhulu anosapho olunye ajolise ekusetyenzisweni kwamandla > 90%
- Ubungqina bexesha elizayo be-V2H / indibaniselwano yejenereyitha okanye i-15 kWh–30 kWh iipakethi zokwandisa
Imveliso yexabiso lokuGcina (LCOS)
Umbane ophantsi
I-CAPEX esezantsi, kodwa i-5 % -8 % ilahleko yamandla eyongezelelweyo kumjikelo ngamnye kunye nokutshintshwa kweseli kwangaphambili kunokunyusa i-LCOS yeminyaka eyi-10 nge-12-15 % ngokuchasene ne-HV.
Umbane oPhezulu
20–30 % CAPEX premium offset by > 90 % RTE kunye 8 000–10 000 ubomi bomjikelo; ikhefu-kwaye ngokuqhelekileyo liphunyeziwe kunyaka wesi-5–6 phantsi kweerhafu zaseJamani okanye zaseCalifornia TOU.
Ukhuseleko kunye nokuThotyelwa kweKhowudi
Umbane ophantsi
Uwa phantsi kwe-SELV (uKhuseleko oloNgezelelweyo oluphantsi lombane); akukho ludibaniso lwe-arc-fault olunyanzelekileyo; I-DIY-friendly kwiindawo ezininzi.
Umbane oPhezulu
Kufuneka idibane ne-IEC 62109-1/2, UL 1973 kunye neekhowudi zokufakela zeHV zendawo; ukujongwa kwe-insulation mandatory, i-arc-fault circuit interruption (AFCI) kunye neeprotocol zokuvala < 5 s emva kokubona impazamo.
Isiphelo:
Khetha i-low-voltage xa inkunzi iqinile, imithwalo ilula kwaye isantya sokufakela sibalulekile. Cacisa i-high-voltage xa ufuna ukusebenza kakuhle, amandla aphezulu ngoko nangoko kunye nelona xabiso liphantsi lobomi ngekWh nganye. Nokuba yeyiphi na indlela, thelekisa ulwakhiwo kwiprofayile yomthwalo-hayi enye indlela-kwaye unyanzelise ukudityaniswa okuqinisekisiweyo ukuvula ixabiso elipheleleyo lewaranti ye-BESS yakho yokuhlala.
