Nha ọkụ eletrik ziri ezi na Sistemụ Njikwa Batrị (BMS) na-ekpebi oke nchekwa maka batrị lithium-ion n'ofe ụgbọala eletriki na nrụnye nchekwa ike. Ọmụmụ ihe ụlọ ọrụ na-adịbeghị anya na-ekpughe na ihe karịrị 23% nke ihe mberede okpomọkụ batrị sitere na mgbanwe nhazi na sekit nchekwa.
Nhazi oge BMS na-eme ka a hụ na oke dị mkpa maka ọrụ nchekwa oke ibu, oke ibu, na obere sekit dịka e mere ya. Mgbe izi ezi nha belatara, batrị nwere ike ịrụ ọrụ karịa windo ọrụ nchekwa - nke nwere ike ibute mbelata okpomọkụ. Usoro nhazi gụnyere:
- Nkwenye NtọalaIji ọtụtụ mita asambodo iji chọpụta ọkụ eletrik na-ezo aka na ọgụgụ BMS. Ngwa nhazi ọkwa ụlọ ọrụ ga-enwerịrị ndidi ≤0.5%.

"BMS a na-agbanweghi agbanwe dị ka eriri oche nwere ebe a na-amaghị ama," ka Dr. Elena Rodriguez, onye nyocha nchekwa batrị na Munich Technical Institute kwuru. "Ekwesighi ịgbanwe nhazi ọkụ eletrik kwa afọ maka ngwa ike dị elu."
Omume kacha mma gụnyere:
