Sistemụ njikwa batrị (BMS) na-eje ozi dị ka netwọkụ akwara ozi nke ngwugwu batrị lithium ọgbara ọhụrụ, yana nhọrọ na-ezighi ezi na-enye aka na 31% nke ọdịda metụtara batrị dịka akụkọ ụlọ ọrụ 2025 si kwuo. Ka ngwa na-adịgasị iche site na EVs gaa na nchekwa ike ụlọ, ịghọta nkọwapụta BMS na-adị mkpa.
Akọwara ụdị BMS isi
- Ndị na-ahụ maka otu cellMaka ngwa eletrọnịkị enwere ike ibugharị (dịka ọmụmaatụ, ngwaọrụ ike), nyochaa sel lithium 3.7V na nchekwa nfefe/nfefe nfe.
- BMS ejikọrọ usoroEjikwa 12V-72V batrị batrị maka e-igwe igwe/skooters, na-egosipụta nguzozi voltaji n'ofe sel - dị mkpa maka ịgbatị ndụ ogologo oge.

Metrics Nhọrọ Dị Mkpa

- Ijikwa ugbu a30A+ mwepu ikike mkpa maka ike ngwaọrụ vs. 5A maka ọgwụ ngwaọrụ
- Usoro nkwekọrịtaỤgbọ ala CAN maka ụgbọ ala vs. Modbus maka ngwa mmepụta ihe
"Enweghị nhata voltaji cell na-akpata 70% nke mkpọ a na-adabeghị aka," ka Dr. Kenji Tanaka nke Ụlọ Ọrụ Na-ahụ Maka Ike nke Mahadum Tokyo na-ekwu. "Wepụta BMS na-arụsi ọrụ ike maka nhazi ọtụtụ cell."
Ndepụta mmejuputa iwu
✓ Dakọtara ọnụ ụzọ voltaji akọwapụtara na kemistri
✓ Nyochaa nso nsonazụ okpomọkụ (-40°C ruo 125°C maka ụgbọ ala)
✓ Kwenye ọkwa IP maka ikpughe gburugburu
✓ Kwado asambodo (UL/IEC 62619 maka nchekwa ọdụ)
Usoro ụlọ ọrụ na-egosi uto 40% na nkuchi smart BMS, nke amụma ọdịda algọridim na-ebelata ọnụ ahịa mmezi ihe ruru 60%.
