Battery Interface Box (BIB)
The Battery Interface Box (BIB) connects or disconnects a battery/battery bank to the DC bus (load or charger) to protect Li-ion batteries against improper use. It communicates with the batteries’ BMS to ensure operation within limits before enabling the main relay. Available variants: 12V350A, 24V350A, 48V350A, 12V600A, 24V600A and 48V600A.
