Interfaces between
battery and vehicle
Efficient interface between battery system and vehicle
To ensure the scalability of the Standardized Battery System, Webasto offers two different interfaces: the Vehicle Interface Box (VIB) and the Vehicle Interface Gateway (VIG). Learn more about the advantages of both products and find the right choice for you.
Vehicle Interface Box (VIB)
The Vehicle Interface Box ensures the scalability of the Webasto Standardized Battery System. It is not only a very efficient interface, but also combines the functions of power distributor, master BMS and fuses in one robust housing. As the main control unit of the entire battery system, the VIB enables the connection of up to 10 Standard Battery Systems. This creates a modular battery system that can be adapted to the requirements of many vehicle types.

Vehicle Interface Gateway (VIG)
In addition to the powerful and intelligent Vehicle Interface Box, Webasto also offers the Vehicle Interface Gateway (VIG). This gives customers even more power for on-road vehicles and with more compact dimensions. This offers greater flexibility when combined with the Standardized Battery System and when used in a limited installation space. At the same time, customers remain flexible in the design of the Power Distribution Unit (PDU).
For off-road use, Webasto offers the Vehicle Interface Gateway Plus (VIG Plus) in addition. The VIG Plus has a very robust housing for use in mobile machines and is CE certified for this purpose.
