BBAT
MISSION
The BBAT is an electronic module mounted
on the CAESAR® weapon system. The BBAT’s
mission is to perform the following functions:
• 
Backup when the vehicle is started,
• 
Power supply,
• 
Overcurrent protection,
• 
Tamper resistance,
• 
Testing.
The BBAT supplies the current drawn by downstream equipment at a voltage of over 20 V when
the engine is started for an on-board network voltage of 5 V < V < 20 V for 30 seconds.
The BBAT protects equipment connected downstream from voltage spikes from the on-board
network. It has built-in overcurrent (short-circuit) protection on each supply line. These protection
systems can be replaced or reset without having to remove or open the module.
