Yawancin takaddun bayanai na Smart BMS suna lissafa ka'idojin sadarwa a matsayin jerin abubuwan da za a duba: CAN, RS485, UART, Bluetooth, wani lokacin ƙari. Ma'anar tana da kwantar da hankali - da yawan jera su, da kyau. Amma jerin bai amsa tambayar siyan ba.

Na'urori biyu na BMS za su iya lissafa tallafin CAN kuma su ci gaba da kasancewa ba su dace da inverter iri ɗaya ba, saboda tsarin saƙonsu ya bambanta. Haka ya shafi nunin NMEA 2000, dashboards na RV-C, da dandamalin EMS (Energy Management System). Tallafin matakin yarjejeniya shine wurin farawa, ba ƙarshe ba.

Wannan labarin yana tafiya cikin tsarin: abin da kowace yarjejeniya ke yi, inda kowannensu ya dace, da kuma yadda ake ƙayyade sadarwa a matakin RFQ (Buƙatar Bayani) don "goyon baya" ya zama "mai jituwa" - bambanci tsakanin aikin da ya haɗu da kyau da wanda ya kai ga gibin aiki.

Abin da Waɗannan Ka'idoji Huɗu Ke Yi a Cikin Fakitin Baturi

Dangane da muhimman abubuwan da ake buƙata na siyan kaya, ga abin da kowace yarjejeniya ke yi a cikin fakitin batir:

Yarjejeniya	Tsarin sadarwa	Matsayin da aka saba	Inda yake zaune
