Dear forum members,
I need some information regarding the battery short circuit protection. I have a 48V lithium-ion battery, connected to it is a battery management system named the (TinyBMS 150A version). Link to the BMS is here. I want to perform a short circuit test of my battery but I am afraid that this short circuit will destroy the BMS. The manual of the BMS says that the BMS or the terminals of the battery should be avoided from a short circuit. My question is how can perform the short circuit test without damaging the BMS. The BMS of course is an expensive device. I am planning to use a fuse with the specification given below:
Rated voltage: 125V
Rated current: 15A
Breaking capacity: 300A @ 125Vdc
Switch-off characteristic: Fast
Melting integral, (I²t): 103.5 A²s
Will this fuse be fast enough to protect the BMS from damage? The rated current of the fuse is 15A, while the maximum output current from the battery for the load would be around 10A.
So, my question is using this fuse or any other fuse would be capable to protect the BMS or should I look for some other way? A schematic of the battery with BMS is attached. Looking forward to handy comments. Thank you very much.
