You can do this by setting their special ability and movement autonomy to high. Then if they're relatively close to a vessel they will try and repair it automatically. The AI picks the ship with the lowest defensive value to attack, so you may want to watch them so they aren't destroyed themselves when they move in to help.

Edit: A few things that would be helpful with repair ships as well. Set their alert status to green so they don't go off and attack something and get themselves killed, and you can keep them in a seperate group and use the guard command to have them follow one of the ships in your main fleet.
