Ajụjụ Ndị A Na-ajụkarị
Q1Otu ụdị BMS ọ ga-ekpuchi 4S ruo 24S n'ezie?
Usoro A na-ekpuchi 4–24S site na nhazi usoro atọ (maka LiFePO4: 4–8S, 7–17S, na 7–24S). N'ime nhazi, a na-achọpụta ọnụọgụ usoro na akpaghị aka n'ime sekọnd 45 nke ike mbụ - ngwugwu 13S na ngwugwu 16S na-eji otu bọọdụ ahụ na-enweghị ntọala aka.

Q2Kedu ihe dị iche n'etiti nhazi nkịtị na nhazi ọrụ?
Nhazi arụ ọrụ na-agbapụta oke ibu site na mkpụrụ ndụ kachasị elu dị ka okpomọkụ, na 100mA na Usoro A - zuru oke maka mkpụrụ ndụ ọhụrụ dabara nke ọma. Nhazi arụ ọrụ na-ebugharị ike site na mkpụrụ ndụ dị elu gaa na mkpụrụ ndụ dị ala, ruo 1A na Usoro T - maka ngwugwu ebe nguzozi mkpụrụ ndụ na-agafe ngwa ngwa karịa ka mmezi arụ ọrụ na-ejide, dị ka mkpụrụ ndụ nwere ikike buru ibu ma ọ bụ nke abụọ.
Q3Kedu ka m ga-esi họrọ n'etiti ọkwa ugbu a na-aga n'ihu na ọkwa kachasị elu?
Kọwaa ọkwa na-aga n'ihu site na ndọta ibu ahụ na-aga n'ihu, ma chọpụta ọkwa kachasị elu megide ihe omume mmụba dị ka mmalite moto. Nyocha abụọ a ga-agaferịrị: nha BMS naanị na ọkụ na-aga n'ihu ga-akwụsị n'oge mmụba; nha nha naanị na oke na-ebu ọnụ na-enweghị isi.
