Obere voltaji
Uru
- Usoro nchekwa nchekwa oke-obere voltaji (ELV); obere ihe ize ndụ mmetụ aka
- Modular, nkwụnye nkwụnye na-egwu; CapEx dị ala maka ezinụlọ nwere nsogbu mmefu ego
- Algọridim BMS myirịta dị mfe
Cons
- Mfu ndị na-eguzogide ọgwụ dị elu (I²R) → 3–5% ntaramahụhụ ume ike
- Ike mwepu nwere oke; adịghị mma maka> 3 kW ibu na-akwado
