Yes it's a controlled fuse, more precisely it's called fusible link.

The fuse can melt, when large current flows through it like a normal fuse, extra it can melt with remote control as it has a in-built heater for melting the fuse.
If the BMS detects overvoltage, then it triggers the remote fuse blowing to prevent an explosion of the battery pack.
