Huddersfield Town's James Vaughan and Joel Lynch scored as the Terriers sealed a third Championship win of the season.
Striker Vaughan made it nine goals in as many matches with a header in first-half stoppage time before defender Lynch drilled in his second
of the campaign from distance after 65 minutes.
Charlton pulled one back though substitute Cameron Stewart - another long ranger - in the 79th minute to make it a tense finish for home
fans in a 12,248 crowd.
