They might not conform to any standard. You likely need to either pull apart the charger and look at where they are connected, or use a multimeter.

I would hazard a guess that the bare/shield is negative.

If the other wires are different sizes, the thickest might be positive. If they're all the same, there may be parallel conductors.
