The MBB module MBB works in 2 Ways :
In « Smart Connect » mode (on the original line of the vehicle)
-If présence of D+ (engine on) = DC/DC charge from +IN to +OUT / 50A
-If cutoff of D+ (engine off) = bypass allowing the cell to be powered by the Lithium / 0-60A battery.
In dedicated line mode, the bypass is never activated. All consumers are connected directly to the battery.
