I have a 48V battery bank using 8 Battle Born BB5024 (24V) mounted in a cargo trailer converted to a camper. Without getting into the details, there was a dead short on one of the batteries causing a total meltdown. There was a lot of smoke and no small amount of drama. Fortunately, other than the acrid smoke and mess from the discharge of a couple of fire extinguishers, there was no other damage.
My question: How should the internal BMS perform in this situation?
The BB website states (for a 12V battery): “Our internal battery management system is rated for three different levels.
- 100 amps continuous (1200 watts at 12 volts) – this means you can pull 100 amps out of the battery when you need it until the capacity is all used up.
- 200 amps for 30 seconds (2400 watts at 12 volts) – if your device has a surge, an individual battery can deliver 2,400 watts for 30 seconds.
- ½ second surge up to the max capacity of the battery. If you have a high moment over 200 amps, the battery will handle this for ½ second.”
Later on the same page, the website states: “The battery will disconnect during a moment of high currents in the system and try to establish reconnection again after 5 seconds.” So, could the scenario have been: max surge for ½ second, 5 second reset, max surge for ½ second, and so on until the battery melted down?
I guess what I am asking is given a very undesirable situation, what protection (if any) should be expected?
Thanks
