If you were in full brake when the battery connector came unplugged, then it probably blew some FET's when that happened. Then you plug it back in and poof here comes the smoke. The voltage generated by braking has to go somewhere, without a battery to dump it into then the controller takes the brunt of it. Battery coming unplugged on a heavy vehicle during a full brake is usually bad.
